Cement and concrete mortars are used to carry out construction activities and improve the territory. The process of manually preparing mixtures is labor-intensive and time-consuming. It does not guarantee uniformity working mixture. But purchasing an expensive concrete mixer for a one-time batch is impractical. The way out of this situation is to make your own concrete mixer. It will allow you to independently prepare a solution with a uniform consistency at minimal cost.

Example of a concrete mixer suitable for home use

Construction of a household concrete mixer and classification of mixers

Units designed for mixing concrete solutions are offered to enterprises and manufactured by home craftsmen in various options. Let's consider the design of the mixer, which consists of the following components:

• a metal frame or bed that combines the units into a single structure. The frame absorbs dynamic and static loads, ensuring the stability of the equipment. For heavy units the frame is stationary, and for small-sized mixers it is equipped with wheels to facilitate transportation. To make a metal frame, you can use a corner or steel profile different section;
• working body designed to increase the homogeneity of the batch. The activator, in contact with the stirred solution, affects the components of the mixture. As a result, the concrete solution acquires a uniform consistency. Blades of complex configuration, special blades, augers and other types of activators are used as mixing organs;
• tank in which concrete is mixed. Such a container is called a barrel and can be made from various materials. For self-made working capacity, you can use those that have lost their relevance and performance household devices– from washing machines to metal barrels. The containers used differ in size and volume, which affect performance;
• unloading device that facilitates and accelerates the drainage of the prepared solution. Design drain mechanism determined by the layout of the concrete mixer, the design and dimensions of the barrel, as well as the weight concrete mortar. Various technical solutions are used to facilitate the unloading process;
• drive station. An electric motor is used as the driving unit. The transmission of torque from the electric motor can be carried out through a reduction gearbox or a belt drive. The gear ratio and power of the transmission must allow the heavy container filled with solution to rotate smoothly.

The concrete mixer differs not only in its design, but also in its mixing methods. According to the principle of operation, mortar mixers are divided into the following types:

• gravitational Distinctive feature of these mechanisms - the presence of a rotating container and a stationary screw activator. Stirable cement mixture under the influence of gravity, without applying any effort, it falls onto the screw axis. Uniform mixing of ingredients is ensured by the action of blades welded inside the rotating tank. The gravity mixing method allows you to prepare concrete with the required degree of mobility;
• forced. They mix cement mortar inside a permanently fixed tank due to the action of moving elements. Performance characteristics and the homogeneity of the working solution prepared in such mixers is much higher when compared with gravity units. The forced mixing principle is rarely used in private housing construction. It is relevant in concrete mixers intended for industrial use.

Gravity concrete mixers 120l

According to the duration of operation, mixers are divided into the following types:

• periodic action, used for private use. They are equipped with a low-power electric motor;
• constant functioning. They are used for industrial purposes and are equipped with a powerful electric drive.

Let us dwell in more detail on the design of devices, the independent production of which is quite simple.

Do-it-yourself homemade concrete mixer - popular designs

Homemade concrete mixer from a barrel

When planning your own production, it is advisable to familiarize yourself with proven designs. Possible various schemes devices, of which the most popular are the following units:

• mechanical concrete mixer. It is a barrel cut along the longitudinal axis, hinged on a metal frame. Inside the container there is a movable shaft with blades. Torque is transmitted from the electric motor through a V-belt drive and gearbox. Unloading of the prepared solution is carried out by tilting the tub. The advantage of this mortar mixer is the reduced mixing time. The disadvantage of the unit is that the solution splashes at an increased rotation speed;
• concrete mixer made from a barrel, equipped with an activator. According to the layout solution, this version of the mortar mixer is similar to the previously described one. The main difference is the use of a whole barrel, in which there is a sealed hatch for loading ingredients and unloading the solution. Torque transmission can be carried out either manually or using an electric drive. In this embodiment, the container rotates, inside of which longitudinal combs are fixed. The quality of the kneading is determined by the number of revolutions, and not by the duration of mixing. Despite the complexity of the design, such mechanisms are mass-produced;
• homemade concrete mixer with mixer. When planning to make a concrete mixer with your own hands, you should pay attention to this option. Despite the complexity of the design of such a mortar mixer, it is worth working on. The device provides increased mixing homogeneity concrete mixture due to the additional degree of freedom. The container with the activator is mounted on a metal frame and can rotate about the longitudinal axis. The frame assembled with the tank has an additional degree of freedom due to the hinged mounting on the supporting frame of the unit. It is important to ensure the tightness of the tank and ease of unloading;
• household vibrating concrete mixers. To create a mortar mixer with a vibration operating principle, you will need a hammer drill increased power, in the chuck of which a metal shaft is fixed. The hammer drill should be rigidly fixed to the frame, ensuring that the shaft is coaxially positioned with the center of the container. On the opposite side of the shaft, a car disk with a smaller diameter should be firmly fixed internal size barrels. The vertically mounted barrel is then filled with ingredients. The components of the cement-concrete mixture are evenly mixed under vibration. When deciding how to make a concrete mixer with your own hands from a car wheel, use this option.

Any design option is suitable for making a concrete mixer yourself.

Problematic points associated with independent production of mortar mixers:

• complexity of manufacturing living conditions without professional training;
• the need to adjust components and elements to ensure trouble-free operation;
• splashing cement mortar at increased stirring frequency.

DIY concrete mixer - pros and cons

Analyzing the advantages and disadvantages, many developers prefer to manufacture concrete mixers themselves. It is necessary to take into account that if you are making a concrete mixer from a barrel with your own hands, you must use drawings only that have been tested in practice.

How to make a concrete mixer from a barrel with your own hands

When thinking about how to make a concrete mixer with your own hands, prepare drawings or sketches in advance. For production, you can sketch a full-scale sample that has proven itself positively under operating conditions. Let's consider the features of self-production of various options.

How to make a manual and electric concrete mixer

The manual version of the mortar mixer is the simplest. It is best suited for preparing small volumes of mixture and is cheaper than electric models. The mixing process is carried out by filling the reservoir with components and then transmitting torque by turning the handle.

Design hand-held device It is a metal frame on which a rotary shaft with a mixing container is mounted in hinged supports. A handle is attached to one side of the drive shaft.

The assembly algorithm involves performing the following operations:

• Welding of metal structures. It consists of two triangular sidewalls connected by jumpers. In the upper part there are bushings for fastening the rotary shaft.
• Preparing the mixing tank. You can use a barrel, milk can or washing machine body as a container. The blades must be secured inside.
• Installing the container on the rotary shaft. It is important to ensure rigid connection and seal the gaps in the shaft mounting areas.
• Fixing the mixing handle and monitoring the tightness of the mixer. For testing, it is necessary to fill the container with water and make sure there are no leaks.

Preparing the Mixing Tank

By following the specified sequence of operations, you can easily make a concrete mixer with your own hands. Drawings or sketches can be adjusted to provide the possibility of using milk can or other container.

If you fasten a V-belt drive pulley or a chain drive sprocket on the side of the shaft opposite the handle, you can ensure the transmission of torque from the gearbox connected to the electric motor. A DIY concrete mixer made from a barrel, driven by an electric motor, will provide increased mixing efficiency.

Homemade concrete mixer with a washing machine engine

Using a 0.18 kW motor with a rotation speed of 1500 rpm, you can assemble an electric drive for a mortar mixer. To transmit torque, a starter gear and a flywheel from a passenger car are used.

Mobile concrete mixer made of washing machine made with your own hands in the following order:

• Weld the frame with the axles for the gear drive.
• Secure the wheels.
• Install the drive gears on the axles.
• Attach the motor and pulley.
• Assemble the belt drive.
• Attach the barrel to the end of the flywheel.

All that remains is to connect the power supply and check how the homemade concrete mixer from the washing machine works.

Conclusion

Based on the recommendations given, it is easy to make a concrete mixer with your own hands. Before starting self-production, it is important to decide on the design of the device. When figuring out how to make a concrete mixer with your own hands, prepare the drawings first. They will help prevent mistakes.

To improve a site, either mortar or concrete is often needed. Kneading it by hand is difficult and time consuming, and the quality of the solution is far from the best: it is difficult to achieve uniformity. Not everyone wants to buy a concrete mixer for periodic use. A good solution is a DIY concrete mixer. You don’t need much money; in terms of performance, homemade units are no worse than Chinese ones, and sometimes even better.

Manual concrete mixer

At a construction site there is not always electricity, and large volumes of mortar and concrete are not always required either. The solution is to make a small-volume concrete mixer that will rotate manually (with a manual drive). The designs of these models are simple and straightforward.

From a milk flask

The simplest manual concrete mixer can be made with an ordinary metal flask (milk used to be sold in these). You will also need pipe cuttings or other scrap metal. The design is simple, such a concrete mixer can be built with your own hands in a couple of hours. The main thing is to weld the frame. Assembling the concrete mixer itself will take a couple of tens of minutes.

Make a frame from round pipe bend the handle. In the upper part of the frame, weld two water couplings (for example). Their internal diameter is slightly larger than the diameter of the pipe used for the handle. The pipe is passed through the flask and welded to the body.

In order for the barrel to spin easily, you need to find the center of gravity. To do this, you can put it on some thin object, and move it forward/backward to find this very center. This is where you will need to pass the handle. Having passed the handle, it is attached to the walls of the case. This is where difficulties can arise: flasks are usually made from aluminum alloy, and the handle can be made of steel. It will not be possible to connect them by welding. The only available way out is cold welding. He is quite real. The remaining modes - with bimetallic gaskets or argon-arc welding at home - are not implemented. Another way out is to weld plates onto the handle, which are riveted to the sides of the flask.

To prevent the handle from playing too much and falling out during operation, nuts are welded to it on both sides of the coupling.

In general, this is all about making a manual concrete mixer with your own hands. For one batch in a 40 liter can you can get 2.5-3 buckets of solution. For use in a country house or on a plot near a house (without construction) it is more than enough.

If there is no can, you can adapt a barrel (thick-walled). Then the problem with welding the handle disappears, but you will have to come up with a system for fixing the lid. You can make something similar to the one that the can has.

The video shows an example of a handmade homemade concrete mixer made from a milk flask. The design is a little different, but not too different. Eat interesting idea— inside the container, dividers are welded to the pipe, which speed up mixing.

From a barrel (manual and electric)

The author called this design a “drunk barrel” because of its unique trajectory. The whole point is that the axis of rotation goes obliquely through the container. Because of this, the solution rolls over from one wall to another. The design is also simple and effective. What is important is that there are no problems with welding dissimilar metals. A drawing of a manual concrete mixer made from a barrel is shown below.

In the upper part of the frame, bearings are installed in the center, into which the handle is threaded. Thanks to them it spins 200 liter barrel easily. Just choose a container with thick walls - it will last longer. No additional blades are welded inside: they only retain the components, interfering with mixing and complicating unloading.

IN original design The loading/unloading hatch is located in the bottom. This is a cut-off part (about 1/3), attached with hinges to the bottom, equipped with rubber sealing around the perimeter and closed with two locks. When loading the barrel, turn it so that the hatch is at the top. When unloading, turn down. The solution moves by gravity into the substituted container, and the stuck one can be removed by knocking on the body with a hammer or sledgehammer.

This design served the author for 10 years, although it was made for a one-time job, but it turned out to be very successful: 2.5 buckets of solution are mixed well in 20-30 revolutions. During this time, it was repeated and improved by neighbors and acquaintances. Most of the modifications concerned the hatch. Experimentally, its most successful design was identified - similar to the one used in a milk flask. This “neck” is welded to the body of the barrel on one side (look at the photo above). They also make handles on both sides so that two people can work.

This design can easily be converted into an electric homemade concrete mixer. A not very powerful engine is installed - 1 kW is enough for a 200 liter barrel, a small sprocket is attached to the axis of which, a larger sprocket is welded to the axis-pipe (to reduce the number of revolutions), they are connected using a chain (from a scooter, for example).

DIY electric concrete mixer from a barrel and a washing machine engine

This concrete mixer is gear type. To make this model you needed:

• galvanized steel barrel 180 liters (diameter 560 mm, height 720 mm);
• washing machine motor - 180 W, 1450 rpm;
• flywheel and starter gear from Moskvich 412;
• two pulleys from a washing machine with a diameter of 300 mm and 60 mm;
• wheels from a garden cart;
• scrap metal for the frame.

Gears, wheels - everything is old, everything was in the garage

First of all, we clean everything from rust, treat it with a rust converter and cover it with primer.

We make a frame from pipes and channels. We strengthen the corners of the frame by welding metal plates. Everything must be tough and reliable. We are making a serious crossbar: a barrel of solution will “hang” on it, and everything will vibrate and spin.

The frame is the basis of the structure. The pipes are almost new))

We weld the pins and the seat for the transmission gears. We remove rust, treat it with a rust converter, and prime it.

We fasten the wheels from the cart. They have wide treads and they have justified themselves: it is not difficult to drag a concrete mixer even just across the site.

We also make structures from pipes for support and installation of all the “filling”.

The second is for greater stability

We begin to assemble the drive. First we place the large gear on the previously welded pin.

We install an assembly in the seat - a small gear connected to a wheel for a belt drive.

We attach the engine to the plate welded in advance.

We hang it so that the two wheels of the belt drive are at the same level. It is also necessary to ensure normal belt tension.

All that remains is to attach the barrel. We make a hole in the center for a large pulley and drill a hole for fasteners. Let's put it in place.

All that remains is electrical part. We connect the cable via

Several photos of the main components. Maybe someone needs to take a closer look.

The second transfer option is from a car disk

The barrel is 200 liters, its edges were cut, bent and welded, forming the usual “pear”.

They made a “pear” from a barrel

The car disk was bolted to the bottom (with rubber gaskets). It was selected so that a recess was formed for the belt drive. A hub was pre-attached to the disk.

Blades were welded inside the barrel to mix the solution more efficiently.

All this equipment was attached to the frame.

Where the plate is welded is the place for the engine. We set it so that the belt runs smoothly. Power was supplied through a toggle switch, and a timer from the washing machine from which the motor was removed was turned on in series.

In general, the rotation speed was 35-40 rpm. Should be enough.

Homemade mixers in video version

If clear general principle How to make a concrete mixer with your own hands, you can modernize and remake it, adjusting it to the existing parts. The videos collected in this section will help.

Crown type

Another option, but not a gear type, but a crown type. By the way, you can buy a crown (cast iron or plastic) and install it on the barrel.

With rollers as support

With a limited budget, buying equipment that will only be needed for one construction project is unprofitable. If companies offering tool rental have not yet opened in the neighborhood, a DIY concrete mixer will be a great way to save money! If you approach homemade device with care, it will last for many years.

Types of concrete mixers

Having previously studied the mechanism of operation of concrete mixers and their characteristics, it will be possible to select a design suitable for the needs of a specific construction. After all, why complicate your work if you can get by with a simple mechanical device?

On the other hand, by loading the concrete mixer to capacity, it will not be possible to finish pouring the foundation faster - this will lead to a banal overload of the engine and its rapid failure.

Mechanical or electrical?

When choosing the design of the future “assistant”, you should immediately decide on the way it will work:

• mechanical concrete mixers - they operate from a manual drive; when mixing a large amount of concrete, two people need to turn the gate;
• electric concrete mixers - work from the mains, but require a motor to be connected good knowledge auto mechanics.

If several strong and resilient people are involved in the construction site, you can get by with a manual concrete mixer. The mixture ingredients are loaded either simultaneously or alternately. The only inconvenience is that designs with a movable barrel, rather than an internal shaft, do not allow adding water during the mixing process. You must stop the barrel, open the hatch and fill it with water. The hatch closes and the mixture is stirred again.

Electric concrete mixers allow you to mix large volumes of concrete in the shortest possible time, but one person does the job perfectly. It should be taken into account that high-power motors require a three-phase network, therefore, when choosing the volume of the tank, the power of the motor should be calculated in advance. If only a 220 V line is connected to the yard, you will have to forget about heavy solutions.

Forced, gravitational or vibration?

Its design will also depend on the operating principle of the concrete mixer:

• forced-action concrete mixers are distinguished by a stationary container in which blades mounted on a shaft rotate;
• gravity concrete mixers mix concrete by rotating the container itself, in which the blades are rigidly fixed to the walls;
• Vibrating concrete mixers cannot boast of great productivity, but they provide a high-quality and homogeneous mixture without bubbles.

At the same time, both gravitational and forced-action concrete mixers can be either mechanical or electrical. The whole difference is that a mechanical forced-action concrete mixer has a horizontal axis, while an electric one can have a vertical one.

To make them you will need metal container. The most basic option is a metal barrel with walls at least 2.5 mm thick.

Vibrating homemade concrete mixers are available to every hammer drill owner. And although it won’t be possible to fill the foundation with their help, it is quite possible to make a poured floor in the bathroom or mix mortar for tiles. At the same time, the design couldn’t be simpler and does not require direct human participation. So even a woman can handle the job.

Concrete mixer volume

An important selection criterion is the capacity of the future concrete mixer. For example, for pouring a foundation, a minimum capacity of 200 liters will be required. It should be taken into account that the finished mixture will be 15-25% less - depending on the loading capabilities.

This volume of concrete can be mixed manually, although it is quite difficult - your hand will get tired.

The homemade device has one more significant drawback– the mixture is often discharged in full. Therefore, it is better to take care of a wheelbarrow of appropriate capacity in advance. If it is possible to make a partial reset mechanism, it is better to take the time to create it. This will significantly simplify the operation of spacious electric concrete mixers and will allow two people to work, loading two wheelbarrows each.

Drawings and design of simple concrete mixers

If the construction volumes are small, you can get by with simple concrete mixers, the creation of which will not require serious labor and financial costs.

Vibrating concrete mixer from a hammer drill

The presence of a mixer attachment is mandatory for any construction work. But holding the drill while it mixes the solution in the bucket is difficult and time is wasted. If you have a manually operated hammer drill impact mechanism, you can quickly make a vibrating concrete mixer:

1. You will need a hammer drill with a power of 1-1.3 kW. Less powerful ones will be ineffective.
2. A vibrator is being manufactured - the main operating part of the concrete mixer. An incorrectly made vibrator simply will not mix concrete. Its shape should resemble a biconvex lens - flat edges and a convex middle. For example, these could be metal plates folded together and fixed. The diameter of the disk is calculated based on 20 cm per 1 kW. For a 1.3 kW hammer drill you will need a vibrator with a diameter of 25 cm.
3. A round container is selected. The distance from its walls to the vibrator should be equal to its radius. So, for a vibrator with a diameter of 25 cm, you will need a container with a diameter of 50 cm.
4. The bracket for the hammer drill is installed. The position of the vibrator is calculated so that its distance to the bottom is equal to its diameter, in in this example this is 25 cm. The amount of solution above the vibrator should be the same.

The readiness of the solution when operating such a concrete mixer is determined by the absence of rising bubbles and the formation of small waves on the surface. If the cement or sand is of poor quality, the solution may not form waves. Then the mixture is ready when it stops moving and gurgling.

Manual concrete mixer made from a barrel

You will need a two-hundred-liter metal barrel itself, metal pipe 2-3 cm in diameter, flanges, grinder and welding machine:

1. A loading hole and two opposite holes for the pipe, which will be the axis, are cut in the barrel. The axle can be threaded either through the center of the barrel or diagonally. In the second case, the mixture will be mixed more efficiently.



2. From the inside of the barrel, 2-3 blades are welded to the walls so that the mixture does not stick to the walls and mixes better. The blades should run along the entire barrel, but not lie close to the walls - otherwise the solution will constantly accumulate in the seams.



3. A pipe is threaded through, its ends are welded and secured with flanges.
4. A stand for a concrete mixer is being manufactured. Its height should be such that it is convenient to load the ingredients of the mixture without raising them too high, but also so that you do not have to get in the way by bending over. On the supports under the axle you need to make oarlocks that will allow the axle to rotate freely. You can use either a hollow tube of larger diameter or bearings.



5. It is imperative to provide a wide, strong and stable base connecting the legs of the supports. This will prevent the concrete mixer from wobbling during operation.
6. The levers are welded to the axle. Do not forget that they should be located opposite each other. The longer the lever, the easier it is to move the barrel. But a lever that is too long is not convenient to use, so you should stick to the golden mean.



7. The loading hatch lid must be tightly closed so that the mixture does not leak out. You can cut a larger lid from the same barrel and glue it around the perimeter with thick rubber. Or you can use part of the same barrel left over from cutting out the loading hole. To do this, you just need to weld a centimeter-long metal strip along the edge and also seal it with rubber.

The concrete mixer has a similar design. open type. Only instead of a moving barrel, blades rotate inside, which are also driven by human effort. To make it, you will need the barrel itself, and pipes of round and rectangular cross-section. The barrel is laid on its side and the top is cut off. It is better to leave as much of the barrel as possible so that you can mix more concrete.

Holes for the shaft are cut on the sides. But, unlike a gravity concrete mixer, the blades are welded onto the shaft itself. You can use any parts, even blades from a combine!

The mixture is also unloaded by turning the entire barrel over.

Such concrete mixers are very budget option, but requires the constant participation of two workers. If you have to work alone, you will need a device with an electric motor. For example, the open type option can be quickly improved by connecting a motor to it.

Electrically driven “factory” concrete mixers

Without having confident welding skills, it is better not to try to replicate factory models of concrete mixers yourself. But if you have an experienced neighbor, you can make excellent equipment from almost nothing! Moreover, such a concrete mixer will serve for more than 10 years, helping in the construction of the entire holiday village.

Homemade gravity concrete mixer made from scrap metal

After this, you will have to travel to recycling collection points and auto dismantling yards in search of the necessary parts:

• metal sheets with a thickness of 2.5 mm for the walls and 5 mm for the bottom of the pear;
• a flywheel from a car, for example, from a Volga or MAZ, a hub and a bendix - for the pear rotation mechanism;
• bearings for tipping the pear (you can get by with the “pipe-to-pipe” system, generously lubricating the rowlock);
• metal pipes square section And different diameters- for the base, seat and a swivel wheel.

When all the materials have been collected, you can proceed directly to the manufacture of a concrete mixer:

1. The body elements are bent and welded together. You can bend steel with a sledgehammer, even if the individual parts do not turn out perfectly even, when welded together they will take the desired shape.



2. While the bulb is not welded together, a rotation mechanism is attached to the lower part, cut from 5mm steel. It is advisable to make it removable - it is easier to transport a collapsible concrete mixer.



3. The parts of the pear are welded together. First, the central and lower parts are combined. To do this, the edges of the central rim are cut and bent inward to limit the exit of the lower part. The lower part is inserted through the top into the central rim and, using tapping with a sledgehammer, is pressed all the way down. Once the edges are aligned, they can be welded.



4. The upper part of the pear is lowered into the central one, the edges of the central rim are also trimmed and bent inward. Using a nail puller, the top is also “picked out” until it stops and is also welded.
5. Blades are welded inside the pear to help mix the mixture. To prevent the solution from accumulating in the seams, the blades are attached to a short distance from the walls.
6. You can start making a seat that will ensure the pear is tipped over. Considering the large weight of even an empty container, you need to take care of the high reliability and strength of the frame.



7. The tipping mechanism must be done on a flywheel with a gear - so even one person can tip over a full container. You can weld a hexagonal wheel or fit any other one.



8. A gearbox is made that will transmit torque from the engine to the pear. The pulleys on the shaft and motor are designed to produce up to 25 revolutions of the pear per minute.



9. To prevent large parts of the mixture from getting into the rotation mechanism, a strip can be welded over the crown, but this step is not necessary.

In principle, the concrete mixer is ready. If desired, it can be painted to protect the metal from corrosion, although during operation it will still acquire a classic gray color.

Forced type concrete mixer made from a tin pan

If you don’t have it, you can order a pan with a diameter of 60 cm and a depth of 50 cm from a familiar tinsmith. After this, all that remains is to fit the mechanism, blades and make a hatch:

1. The center of the container is marked - this is where the shaft will be located. A hatch is cut for unloading the mixture. It’s easier to cut a rectangular one, but then the whole mixture will break into a wheelbarrow. It is better to make a rotating semicircular hatch.



2. To do this, a rod is welded in the center of the cut out semicircle, on which the hatch will rotate. To prevent the mixture from leaking out, a strip is welded above the cut of the hatch, under which the curtain will move.





3. In an inverted state, a motor with a gearbox is attached to the installed bearing. To securely fix the engine and ensure the required belt tension, the engine is installed on slats welded to the bottom of the container.



4. To strengthen the frame of a container made of 2 mm thick steel, a rim of steel rod or pipe must be welded along the upper edge. You can also make stiffening ribs on the sides and bottom of the container.



5. Once the wheels, support and rotation mechanism are installed, the entire structure can be turned over. The blades are attached to the shaft and everything is fixed with one bolt - so that the structure can be easily disassembled. It is important to correctly think through the position of the paddle blades - one should remove the solution from the walls, the second should separate it from the bottom, and several more should mix the middle.





6. You can get by with a construction made from scrap and a cross from a plumbing flange. If the blades are made movable, their position can be adjusted depending on the type of mixture.

The forced action concrete mixer is ready! You can mix almost any mixture in it, make them liquid or dense, add crushed stone of large and small fractions. The same concrete mixer, but of a horizontal type, can be made using the drawing.

The process of assembling a concrete mixer from a steel barrel is clearly shown in the video:

This is one of the simplest ways to make the necessary construction equipment with a minimum of cost!

Many people like to carry out repairs on their own plot with their own hands. To fix the foundation of a house, fill paths, or install fences on posts, you need a machine such as a concrete mixer. There is no point in purchasing an industrial model, because it will be very expensive. In this case great solution You will be able to make a concrete mixer yourself, which will not require large financial costs. So how to make a concrete mixer yourself? Thanks to the presented video, you can clearly see the entire manufacturing process.

Why is a concrete mixer needed?

Many people think that it is not large number The solution can be easily mixed with a shovel. However, this results in a very low quality mixture. The fact is that it is very difficult to stir the solution in a trough with a shovel. Such physical activity not everyone can do it, so easier to install the concrete mixer, assembled with your own hands from a barrel. In addition, if you mix a large amount of the mixture, the composition will end up dry. The solution begins to lose moisture much faster than it can be stirred to the required consistency.

Concrete good quality It won’t work even if you use a drill. When you attach it to the bracket, lumps of sand remain in the mixture. The drill must not only spin, but also move back and forth and in a circle. Often the tool cannot withstand such stress and breaks.

To understand the principle of operation of a homemade concrete mixer with your own hands, which is made for a small amount of work, it is necessary to consider the process of mixing the solution. There are 3 ways:

• gravity method;
• vibration method;
• mechanical method.

Gravity method . This method is not used in industry, because the resulting cement has low quality. As a result of gravitational mixing, the container tumbles over, the components begin to “plop” on top of each other and mix into a relatively homogeneous mass.

Vibration method. Counts the most reliable production method concrete in industry. In the fixed tub, a vibrating mixer begins to move, resulting in a high-quality solution.

Mechanical method. Can only be used in conjunction with gravity. In this case, either the mixer begins to rotate in a stationary tub, or the tub with protrusions inside rotates.

Concrete mixer manufacturing technology

There is a large number homemade units, which are adapted for the production of concrete. The simplest design can be made from an ordinary milk can, a large saucepan, or old boiled milk. Its drawing is quite simple, and its manufacturing technology is even simpler:

• weld the container to the axis;
• insert a stick, a piece of pipe or a rubber band into the lid and pull the lid very tightly towards the handles;
• to simplify the design couplings are not used, and cut arc-shaped recesses in the frame and lay the axle on them.

To make a more practical unit, it is necessary to use other drawings.

Stages of making a concrete mixer with your own hands

Making a container

Before you start creating a concrete mixer with your own hands, you should choose a container. Best to use for this metal barrels, which can hold at least 200 liters. Exactly this volume is considered optimal in order to knead required quantity concrete at a time. It is better not to use plastic tanks, as they will not last long.

To make a concrete mixer you will need a barrel with a lid and a bottom. If the container initially does not have a lid, then it should be welded by cutting it out of a sheet of metal. After this, flanges with bearings should be attached to the bottom and lid of the barrel. A hatch is cut out in the side, through which the components of the solution will subsequently be poured. It is best to make such a hole closer to the end of the container, which will be lower during operation of the concrete mixer. The cut out part of the barrel will be used as a hatch cover. It is secured using hinges and some kind of locking device.

In order for the solution to mix better, blades are welded to the inner walls of the barrel at an angle of 30 - 40 degrees. The angle of inclination is calculated in such a way that during the mixing process the concrete can be “pushed” outward. In addition, such the blades can be fixed not on the walls, but on the shaft of the device itself.

If suitable container If you can’t find it, you can make it yourself. To do this you will need the following tools and materials:

• sheet metal 1.5 - 2 mm thick;
• welding machine;
• rollers;
• wooden mallet or hammer.

Before you start cutting metal, drawings should be prepared indicating the required dimensions. To make the body of a concrete mixer, you will need a central round section, the bottom of the container and two truncated cones that make up the bottom and top part designs. Parts cut according to the markings must be bent into rings. It is more convenient to do this using rollers. After all parts have been adjusted, the seams are securely welded.

Base installation

A homemade concrete mixer must have a reliable and stable base. Otherwise, the structure may tip over during operation. If it is not intended to load a large amount of concrete into it, then it is better to make the frame out of a square one wooden beam , having a cross-section of 10x10 or 15x15 cm. To ensure that the base of the structure does not suffer from vibration during operation, you should use “half-tree” or “tenon” type connections. After assembly, all joints must be properly glued and tightened with self-tapping screws.

If you want to create a more reliable and durable unit, you should give preference to a frame that welded from metal corner size no less than 45x45 mm. You can also use a channel. If there is no gas welding machine, then the frame is secured using rivets or nuts and bolts.

If there is such a desire, the base can be equipped with wheels. This will require an axle without bearings and the wheels themselves. This concrete mixer is easy to turn over and move. When assembling the base, it is necessary to provide handles. With their help, the device can be moved.

During the assembly process, the frame must provide space for the engine. Also a counterweight will be needed so that when unloading concrete the structure does not tip over. If you plan to unload the solution with a shovel, then in this case a counterweight will not be needed. All these points must be provided for during the creation of the drawing.

Engine installation

To make the concrete mixer more efficient, you need any single-phase motor whose rotation speed is no more than 40 rpm.

Many masters who create homemade design, it is advised to use electric motors from old washing machines that have failed, such as “Volna” or “Chaika”. Such motors can operate long time and don't overheat. When choosing a motor, you should remember that the optimal rotation speed of the tub is 20 - 30 rpm. For this, various gearboxes are used. However, optimal and simple option is the use of a pulley and a drive belt.

Instead of a washing machine motor, You can use a motor from a motorcycle or a gasoline-powered moped. In this case, the concrete mixer will not require power supply and can be used in any conditions. The engine is mounted using 4 bolts to the bracket or frame, which are welded to the gearbox housing.

However, a homemade concrete mixer can also operate using manual control. In this case, neither electricity nor gasoline will be needed. Such a simple device is mobile, easy to assemble, and anyone can operate it. Its only drawback is the presence of an assistant to mix the solution.

Finally, a shaft is threaded through the container of the structure. To make the device more stable, it should be dug into the ground at an angle of 30 degrees.

Thus, to make a concrete mixer with your own hands, no special skills are needed. The manufacturing process can be seen more clearly in the video. Before you start assembling such a device, you should use the drawings. They will help you correctly and accurately create a homemade design without major financial investments.

No construction project of any scale is complete without a high-quality concrete mixer. The device is not cheap, but it is periodically necessary at the dacha or in the household, so many people think about buying it even in cases where the question of global construction is not at issue. You can get out of this situation by building a high-quality concrete mixer yourself. Today we’ll look at several options on how to make this easier and cheaper.

Concrete mixer. Why is it needed?

A homemade concrete mixer with your own hands opens up a lot of prospects for working with concrete and not only with it, but with everything construction mixtures. After spending some time building a device of any complexity level, you can get reliable design, which will help out not only its owner, but also its neighbors more than once.

It is useful for preparing mortar when laying brick, foam block, stone, and for building foundations different types, for the manufacture of decorative elements and landscape design, for example, garden paths. The price of the most inexpensive concrete mixer is about 8 thousand rubles.

Prices for concrete mixers

On average it will have 20-25 liters of batch, and the power can be from 150 W. Not the best choice even for periodic use, especially for construction. The mixing drum in such concrete mixers is belt driven by an electric motor, and this is the most simple design, which you can buy.

More advanced and productive models are in more serious price category. About 22 thousand piglets for a concrete mixer with a rim driven mixing drum. Its volume will be from 120 to 140 liters, which is approximately 80 kg of the finished mixture. It's not yet professional model, but this can already be used for not very large-scale construction. Now that we are guided by the prices and characteristics of ready-made concrete mixers, we can consider options for building it ourselves, and the design can be chosen depending on how many cubes we need in a ready-mixed concrete mixer.

Choosing a concrete mixer design

For a summer residence or personal plot everyone will be able to choose a device of such productivity that they need it, and not overpay for extra cubic meters of ground air. This is the main advantage of building a concrete mixer yourself. The second advantage is that you can use literally everything you have at hand and build a concrete mixing plant with minimal costs in terms of money and time.

That is why the choice of the device concept remains with the owner. We publish photos of the most interesting and simple devices, but you can always complicate the design.

Required design elements

Be that as it may, any concrete mixer must have the following elements in its design so that it can minimally perform its functions:

How to make a frame and select an electric motor

The frame and frame of a concrete mixer can be made of wood, but there are many questions about the practicality of such a design. As a temporary option, you can use 15x15 timber, but whether this makes sense is for everyone to judge individually. The optimal option for durability and strength is a welded frame made from angle or rolled steel of any profile. We have presented several drawings in the photo as an example.

If you decide to install an electric motor, usually you use a motor from a household washing machine. Empirically, it has long been calculated that 25-30 revolutions per minute at the outlet of the gearbox is quite sufficient for high-quality mixing of any mixture. The electric motor from a washing machine can provide good torque, the motor is quite durable, especially if it is used in a gentle operating mode. For more productive and high-volume concrete mixers, three-phase electric motors are used.

Mandatory geometric parameters for a cylindrical type concrete mixer - the angle of inclination of the main axis is about 40-45 degrees. In this case, a folding mechanism is needed to unload the finished mixture. There are options for homemade concrete mixers made from a barrel with a horizontal mixing drum. In this case, a hinged hatch is installed in the barrel, which closes tightly during the preparation of the concrete mixture, and opens during unloading, and the finished mixture falls into a container prepared in advance.

There are many designs and types of homemade concrete mixers. The main thing when designing and building it is patience and the ability to use basic tools and welding, which is what we wish for you. Good luck to everyone!
