# How to make a concrete mixer manual and electric drive

Almost one in three knows from personalexperience that roach with a shovel over the old trough for kneading the mixture - is not the most pleasant experience. And every second is aware of this from the stories of their friends. Therefore, the question of how to make the mixer with their hands not idle. After a little strained at the beginning, you can significantly simplify your life later on. Consider how easy it is to implement this venture in life, and what pitfalls may be encountered in the process.

## Existing embodiments of the devices and their differences

The basic division is by the way exactly how the process of kneading the mixture. There are the following four basic ways that are used in different models.

• The gravity method

Implemented by the auxiliary forces of ourPlanet Earth. Rotating drum raises a certain number of the mixture, which then falls back to the bottom of the remaining remnants of its walls. So, striking again and again on itself, and the mixture is stirred and appears to result in a sufficiently satisfactory for the form builder. Use this option in a large-scale construction project impossible. The quality of the finished product is far from perfect, and the volume of the mixture is kneaded at one time a small (otherwise will suffer quality).

• Mechanical method

The fixed capacity required backfilledcomponents are mixed together by rotating around its screw axis. In addition to the designated motion should move on the screw periphery capacitance if its diameter is much smaller than the final diameter. This option is not used for large volumes of work, as the cost of electricity has a very large. When attempting to use in the home of a simplified version (drill with paddle mixer) can also comprehend the failure. The device is not designed for continuous operation, and if to take breaks, a mixture hardens.

• Vibration method

The mixture was kneaded in a stationary container atusing a special mixer that creates a wave in it. When using this method eventually get a very high quality solution. The most commonly used in the works related to the construction of complex structures (eg dams). The home is almost never used.

• Combined methods

They are the most common. Combined mechanical and gravitational kneading method. Either this rotating container with rotating nozzles within it for mixing, or is a rotating container with rigid edges at its interior walls. The quality of the finished product is several times higher than that of a gravitational method, and power consumption is several times smaller than when using only a mechanical method.

## The process of assembling a manual actuator

Before you begin to understand how to make a concrete mixer, clarify what tools and parts we need while working.

• Vessel with a volume of about 200 liters. The material has a special meaning not, it may even be a durable plastic.
• The metal rod of circular cross section, which will play the role of an axis.
• Nails 200 mm, which will be part of the comb is used for a more thorough mixing.
• Two metal rack, the length of which is equal to the height of the container.
• Metal shaped tubes, which are necessary to create a support frame and arms.
• The crown of the crankshaft to fix the axle.
• Door hinges.
• Two loops (on-hook lock).
• Rubber compressor.

The photo does not show one very importantelement. To design lasts as long as possible, it is necessary to strengthen the abutment with the drum axis. On the top and on the bottom of the container lid is better to weld two metal rails that crisscross each other

Almost all the connections are made by welding but attachment to the crown of the tank and side cover.

The assembly is made in the following sequence:

• Welding pedestals.

The height of the racks is adjustable in its sole discretion,but it is desirable that the finished structure is not less than 1.2 m. Otherwise, the process of filling the tank and release it from the mix is ​​problematic. Width perpendicular to the poles should be about twice the width of the tank. Oblique props welded at an angle of 45 degrees.

• The keying holes for doors.

Dimensions of holes are determined individually, butmost appropriate indicators -. 30x30 cm cut-out portion to reduce the necessary bit, not more than 0.5 cm (one on each side). By opening the perimeter glued rubber seal. At the very door and a tank near the edges of the holes are attached the two rings to the castle, which will be stapled wiring.

• Securing the rake inside the tank.

By the metal rails welded nails in increments of 5-10 cm. Reiki is welded inside the tank opposite to each other.

• Mounting axis.

To the sides of the container with screws and nutsattached crowns. The threaded hole axis, which is welded to the joints of the Convention. Fastening strengthened welded crosswise strips.

• Fastening handles to the tank and support frame.

The top of the pedestal should be betweencapacity and the edge axis. The uprights are drilled hole axis. Mounting is by two metal washers, which are fixed with screws and nuts. Handles in the form of "T" letters are welded to the axle ends.

## The process of assembly of the electric drive unit

The framework itself together with the tank can be made almost the same as previously described. But instead of sticks, we performed a manual kneading, set a special device with a motor.

Commonly used in plant cellsring gear, but for us it will not be the best solution. Firstly, its cost is quite high. Secondly, to make such a self is also not everyone's strength.

A worthy replacement can serve as a device assembled from the following components:

• flywheel (from any, even the very old, the car);
• gear-bending (using its starter motor is connected to a flywheel).
• wheel hub.

To provide the desired speed, it is necessary to supplement even gearing and belt

In addition, there is another difference. The axis is not welded to the tank, it will rotate using the motor and the capacity itself will remain stationary. Inside the tank is not welded ridges, instead welded to the blade axis, which will carry out kneading.

The photo shows the open design, but it is inconvenient fact that when a great rotational speed greatly sprayed mixture. Preferably after mounting blades welded on top of the second part of the tank

Separate production of concrete mixerIt will help speed up the construction work at least three times (in the case where the manual option is used). In addition, you get rid of the need not only to buy and expensive but also less expensive not rent the unit.
