The concrete mixer is mainly composed of the stirring cylinder and its auxiliary supporting part. Mixing cylinder is a concrete loading container, it is made of high quality wear-resistant steel plate, in order to be able to automatically install, unloading concrete, the wall welded with a special shape of the spiral blade. The concrete moves along the helical direction of the blade during rotation and is mixed and agitated during continuous lifting and turning. During the process of feeding and transportation, the stirring cylinder is rotating, and the concrete moves inward along the blade. When the material is discharged, the stirring cylinder is reversed and the concrete is discharged out along the blade. The rotation of the agitator cylinder is ensured by the hydraulic drive. Load capacity of 3 to 6 cubic. Of the concrete mixer truck is generally used by the car engine through the power output shaft to drive the hydraulic pump, and then by the high pressure oil to promote the hydraulic motor drive mixing cylinder, loading capacity of 9 to 12 cubic meters by the vehicle-assisted diesel engine driven hydraulic pump hydraulic motor. The blade is the main part of the agitator, and damage or severe wear will cause uneven mixing of the concrete. In addition, the blade angle if the design is unreasonable, but also make the concrete segregation.
