The main truck engine power take-off mode is adopted for the mixer truck. The function of the power take-off device is to take out the engine power by operating the power take-off switch. The hydraulic system drives the mixing drum. The mixing drum rotates in the forward direction during the feeding and transportation process, so as to facilitate the feeding and mixing of concrete. When discharging, it rotates in the reverse direction, and the power connection with the engine is cut off after the end of the work. The hydraulic system converts the engine power taken out by the power take-off into the hydraulic energy (displacement and pressure), and then outputs the mechanical energy (speed and torque) through the motor to provide power for the rotation of the mixing drum.

　　混凝土搅拌车罐体优势：

　　Advantages of concrete mixer tank:

　　搅拌车灌体前封头采用8MM合金钢材料、筒体6MM合金刚耐磨材料，带气压供水装置，流水线生产，搅拌筒整体拼焊工装设备保证产品质量，全自动环缝，纵缝。内部叶片采用5mm细晶粒合金钢，采用UG和CAD计算机仿真技术设计成型，由技术人员结合规定，融合日本派和欧美派的风格重新设计，角度合理，搅拌更加均匀，卸料残存率更低，改进了传统搅拌过程中易出现的石子与水泥混合不均匀与叶片易磨损的现状;进料速度>3.8方/分，出料速度>3方/分钟，残留率<0.2%。

　　The front head of the mixer body is made of 8mm alloy steel and 6mm alloy wear-resistant material. It is equipped with air pressure water supply device. It is produced by assembly line. The whole mixer body is assembled by welders to ensure the product quality. It is fully automatic with circular seam and longitudinal seam. The internal blade is made of 5mm fine grain alloy steel, designed and shaped by UG and CAD computer simulation technology, redesigned by technical personnel in combination with national regulations and the styles of Japanese and European and American schools, with reasonable angle, more uniform mixing, lower residual rate of discharge, which improves the current situation of uneven mixing of stone and cement and easy wearing of blade in the traditional mixing process; Feed speed > Three point eight M3 / min, discharge speed > 3 m3 / min, residue rate< 0.2% 。
