Forced action concrete mixer: types of concrete mixers,

Concrete mixer is an important element in the performance of any construction work, as it allows not only to save time and effort in preparing the mortar, but also to improve the quality of concrete. True, not everyone can afford it, as the price of good concrete mixers is quite high. However, you can save money and do it yourself.

Next, we take a look at the most common constructions of forced-action concrete mixers and consider in detail how they can be made independently.

Types of concrete mixers

To date, no construction can do without concrete mixers, because, physically, it is physically very difficult to mix the solution of cement, sand and rubble with your own hands. Therefore, it is not surprising that this process has long been automated.

I must say that on construction sites you can see a variety of designs of concrete mixers.

However, they are all conditionally divided into two types:

• Gravitational action;
• Forced action.

Now consider the features of each species.

Gravity type concrete mixer

The principle of operation of the gravitational apparatus is that the mixture is placed in a special drum, which rotates. In this case, the solution rotates with it and falls away from the walls under the force of gravity. On the walls of the drum there are blades that improve the quality of the batch, and also do not allow the solution to stick.

This type of concrete mixers is good because they can be used to stir not only concrete solutions, but also any other types of liquid and dry mixes.

Forced type concrete mixer

The main difference of this type of apparatus is that the drum in them remains stationary, and stirring occurs due to the rotation of the blades. Such concrete mixers can be used when mixing any type of concrete mixes.

Not even the most powerful mixer of this type is capable of producing 0.1-0.45 cubic meters of solution in five minutes of work. Moreover, the concrete will be more homogeneous than the mixture made in other types of machines. Performance depends largely on the volume of the drum, as well as on the design of the blades.

Main construction details

Forced Concrete Mixer своими руками изготавливается из нескольких основных узлов:

• Engine;
• Gearbox;
• Grandma at 200 l;
• Vala;
• Blades;
• Frames
• Bearings.

In addition, to collect all the details in a single structure, you need the following tools:

• Bulgarian;
• Drill;
• Welding machine.

Training

Before starting work, you should prepare drawings of a forced-action concrete mixer. This will facilitate the work somewhat, and also allow you to avoid mistakes and alterations.

I must say that there are various designs of such units and first of all they differ in the location of the drum. He might be:

Drawings of a forced-type concrete mixer can be performed independently by looking at the finished structures, or found on the Internet.

Assembly of the mixer with a horizontal arrangement of a drum

Now let's look at how a forced concrete mixer is going to do with a horizontal tank:

• The first step is to assemble the frame, for this you can use the metal corners.. The easiest way is to make two identical triangles. Corners are interconnected by welding.

Since the design will be quite heavy, on the one hand it is possible to provide an axle with wheels. In this case, one frame triangle should be smaller than the other. Its size is selected depending on the radius of the wheel.

• Next, on one side of the triangle, it is necessary to weld the platform for mounting the gearbox.
• After that, an axle with two brackets is attached to the frame, which are welded to the gearbox.

• Then the sidewall of the barrel is cut off to load the drum, after which it is mounted on the frame. The drum can be rigidly fixed by welding, or rotate around an axis, for easy unloading of the finished mixture. In this case, the design is more complex, in addition, it is necessary to provide for the fixation of the drum during operation of the mixer.
• Next, in the lower part of the frame, a platform for the engine is performed and the unit is installed.. Mounting the engine is best done by bolting.
• After that, the blades are welded to the mixer axis, which will stir the solution.
• At the end of the work, the gearbox should be connected to the engine using a belt that drives the drive.. For this, the pulleys of both mechanisms should be located in the same vertical plane.

Tip! For the manufacture of the frame, you can use the corners of the old bed.

Now the self-made concrete mixer of forced action is ready, it remains only to check it in work.

Tip! In the manufacture of such a concrete mixer, you can perform a handle that will allow the axis to rotate mechanically. Thanks to this, it will be possible to use a concrete mixer even in the absence of electricity. After all, it is much easier to turn the handle than to knead a concrete solution with a shovel.

Assembling a concrete mixer with a vertical arrangement of the drum

The design of the device of this type differs significantly from the above described machine.

To make a similar forced concrete mixer with your own hands, you must perform the following steps:

• The first step is to cut the bottom of the barrel and cut the neck to provide a hole for the axis.
• Next to the barrel must be welded four corners to create a support. The lower part of the "legs" strengthened jumpers, which will serve as the basis for the platform of the engine and gearbox.

• Next, you need to install the shaft in the tank and perform the system of its mounting. As a result, the shaft must be rigidly fixed at least two points. For example, in a barrel it is possible to provide a bearing that will hold the axis.
• Next to the shaft you need to weld the blades, which ensure the mixing of the solution.
• After that, at the bottom you need to perform a platform for the installation of the remaining mechanisms.
• The next step is to install the gearbox and the engine, after which a belt is put on their pulleys that drives the drive. When installing the engine, it is desirable to provide a belt tension adjustment system.

Tip! When performing concrete work, care should be taken not only of the concrete mixer, but also tools for further material processing. The most common operation is cutting of reinforced concrete with diamond circles, as well as diamond drilling of holes in concrete.

Here, perhaps, all the main points of manufacturing concrete mixers. Of course, its productivity will not be as high as in the case of pre-fabricated machines, which in the first 20 seconds stir the solution to readiness about 80 percent, but it is quite enough to carry out private construction work. Moreover, it is possible to mix with it using a concrete solution with rubble, and without coarse filler.

Conclusion

Having at least a little experience with metal and welding machine, it is quite possible to make a concrete mixer on your own. Of course, we considered only the main points of manufacturing the structure, so before starting to work you should consider all the technical points to the smallest detail, or use ready-made drawings.

The result of such work will be significant savings, and at the same time, simplifying the construction process. From the video in this article, you can get more information on this topic.
