Structural Principle of Concrete Mixer Truck

Concrete mixer truck concrete mixing by the transport vehicle chassis and special equipment components. China produced more concrete mixer truck chassis with two types of vehicle manufacturers to provide universal chassis. The private sector including power take off, the mixing tube before and after the brackets, gearbox, hydraulic system, the mixing tube, the control mechanism, cleaning system. Working principle is to take power by the power plant will remove the vehicle chassis, and variable drive pump hydraulic system, the mechanical energy into hydraulic energy to pass quantitative motor, motor and then drive reducer, speed reducer driven by a stirring device, on the concrete for stirring.

1. Take power plant

Domestic mixer truck to take power by way of the main vehicle engine. Take the role of power plant to take power through the manipulation of power switch out the engine, hydraulic system driven by the mixing tube, mixing the feed tube in the forward rotation and transport in order to facilitate the feeding and mixing of concrete, the material time in the anti- to the rotation, after the end of the work and the engine cut off the power connection.

 

2. Hydraulic system

Will be removed by the power take off engine power, into hydraulic energy (displacement and pressure), and then the motor output to mechanical energy (speed and torque), provide the impetus for the rotating mixing drum.

3. Reducer

The hydraulic system, motor output speed slows down to pass the mixing tube.

 

4. Control mechanism

(1) control the mixing tube rotation, so that the feed and transport in the forward rotation, reverse rotation when the material.

(2) control the speed of mixing tube.

5. Agitator

Mixing device consists of the mixing tube and the auxiliary support components. Is the concrete mixing drum containers, rotating spiral concrete direction along the blade, in the continuing process of improvement and changes the subject to mixing and stirring. In the process of charging and transport, the mixing tube is transferred, concrete movement along the blade to the inside, the material, the mixing tube inversion, concrete discharged outward along the blade.

Leaf is the main component mixing device, damaged or badly worn concrete mixing will lead to uneven. In addition, the blade is unreasonable if the design point of view, but also segregation of the concrete occurs.

6. Cleaning system

 

The main function of washing system mixing tube is clean, and sometimes also used to dry materials in transit mix tube. Cleaning system is also a cooling effect on the hydraulic system.
