cement mixer truck also known as concrete mixer truck, is used to transport concrete mixing construction special truck;Because of its appearance, it is often called a field snail car.These trucks are equipped with cylindrical mixing cylinders to carry the mixed concrete.During transportation, the mixing drum will be kept rotating to ensure that the concrete transported will not solidify.After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent hardened concrete from occupying space and making the volume of the mixing drum smaller and smaller.
Cement mixer truck is mainly composed of a mixing cylinder and its auxiliary supporting parts.Mixing cylinder is the loading container of concrete. It is made of high quality wear-resistant steel sheet. In order to automatically load and unload concrete, its inner wall is welded with spiral blades of special shape.When rotating, the concrete moves along the spiral direction of the blade and is mixed and stirred in the process of continuous lifting and turning.In the process of feeding and transportation, the mixing cylinder is turned forward and the concrete moves inward along the blade. When the material is discharged, the mixing cylinder is reversed and the concrete is discharged outward along the blade.The rotation of the mixing cylinder is guaranteed by the hydraulic drive device.The loading capacity is 3~6 cubic meters.In general, the cement mixer truck is driven by the automobile engine through the power output shaft to drive the hydraulic pump, and then the hydraulic motor is driven by the high pressure oil to drive the mixing cylinder. The loading capacity is 9~12 cubic meters, and the hydraulic motor is driven by the hydraulic pump driven by the on-board auxiliary diesel engine.Blade is the main part of the mixer. Damage or serious wear will lead to uneven concrete mixing.In addition, the blade Angle if the design is not reasonable, will also make concrete segregation.

The working principle of cement mixer truck:
Power and power output by the second class chassis full power through the shaft power to the hydraulic pump, hydraulic pump can produce hydraulic through tubing to the hydraulic motor, hydraulic motor to convert hydraulic energy into kinetic energy and through reducer reducer increasing twist to the mixing tank, by adjusting the (double-acting variable) servo controller of hydraulic pump Angle so as to realize the drum and reversing and speed, the size of the in order to realize the concrete charging, stir, stir, discharging operation.
