The main engine power take-off mode is adopted. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch, and drive the mixing drum through the hydraulic system. The mixing drum rotates forward in the process of feeding and transportation to facilitate the feeding and mixing of concrete. It rotates reversely when discharging, and cuts off the power connection with the engine after the end of the work.
The engine power taken out by the power take-off device is converted into hydraulic energy (displacement and pressure), and then the motor outputs mechanical energy (speed and torque) to provide power for the rotation of the mixing drum.
After decelerating the speed of the motor output in the hydraulic system, it is transmitted to the mixing drum.
(1) Control the rotation direction of the mixing drum to make it rotate forward in the process of feeding and transportation, and reverse rotation when discharging.
(2) Control the speed of mixing drum.
