Electric cement mixer with their hands

mixer device

this device system elements is not a big deal, so it will be the establishment of the power of man, have minimal knowledge in engineering.

So mixer mechanism including your device as follows:

• drum;
• support elements;
• motor.

main thing - to connect all the parts to ensure smooth operation of the machine.But do not forget that the engine in the mixer solution is quite powerful, and the design includes movable components.Therefore, when working is to observe safety precautions.

Manufacturing kneading drum

Step 1. Produce drum mixer

frequently used for such purposes, the iron barrel, which shall be not less than 200 liters.It is also possible to use a similar container made of plastic only.The downside of using the barrel as a mixing chamber is its high altitude, which in turn can complicate the final solution extraction process from the machine after cooking.

The best option would be - cook mixing chamber made of sheet steel, while trying as much as possible to repeat the form of purchased vehicles.The drum dimensions can range from 200 to 300 liters.

electric mixer blades

also concrete mixer drum unit includes blades that are located inside the chamber.If the mixing container is constructed of metal, the blades need to be welded to the inner surface of the drum.If the kneading chamber is made of plastic barrels, you should attach them to the bottom of an iron drum.The blades can be made of iron profile or corner.

connection to the motor

Next, you need to make an element with which to set up the drum docked with the motor, which can be gear or belt.For this purpose the housing chamber kneading welded connecting ring (in the case of the belt connection) or teeth (if a compound gear).

Mounting support elements

frame for concrete mixing mechanism can be built of wood or metal.At constant vibration may shatter a wooden base that will not happen with welded metal base.For iron base suitable cutting channels, pipes or corner.It is better to make the frame directly to the wheels for mobility devices.

also in the construction necessary to provide PTZ mechanism that is mounted from a metal pin and a bearing.It is worth to him priladit handle design for comfort and control.

Motor selection

rotating mechanism must have the capacity speed of 20 to 50 units per minute.For this fit the engine of the washing machine, you can also use single-ended low-power motors.The specifics of working with concrete mixer requires that the engine was equipped with a connection to the network and switch.There is also a requirement for the number of revolutions.If the motor will spin the drum faster than 50 revolutions per minute, the solution is sprayed.

Assembling

now is to connect all the selected items together.This process consists of several sequential steps:

• drum kit on the frame and securing it.It is necessary to make sure that the foundation can withstand the weight of kneading chamber.
• Engine installation under the frame and securing according to the chosen system of motor connection with mixing chamber.
• Mains power connection and trial run idle.

the presence of obvious errors in the design, which emerged during a trial run, is to fix them.

Useful tips for

When used in the construction of a homemade cement mixer should pay attention to several important aspects:

• You can not run the machine if it is in a solution which needs further stirring.It is best to remove the remains of the building mass, and then re-throw them into an already running drum.
• In the process of mixing the solution filling chamber is not more than 2 thirds of its volume.
• solution ingredients should be added in the following sequence Before kneading process: water, sand, cement and other ingredients.
• After each complete day of work should not be left drum is not washed.The solution may freeze on the chamber walls and rendered unusable the entire structure.
