1. Power take-off device
The automatic loading mixer adopts the main vehicle engine power take-off mode. 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 stirring 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.
2. Hydraulic system
The power of the engine taken out by the power take-off device (generally full-function power take-off device at the rear) is converted into hydraulic energy (displacement and pressure), and then output to mechanical energy (speed and torque) through the motor 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 of the charging mixer.
4. Control mechanism
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.
5. Cleaning system
The main function of the cleaning system is to clean the mixing drum, and sometimes it is used for dry material mixing during transportation. The cleaning system also cools the hydraulic system.
6. Closure device
The rotary sealing technology is adopted in the fully closed device to seal the inlet and outlet of the mixer, and a series of problems such as water evaporation, mortar layering, concrete spreading and driving safety of the traditional mixer truck are solved.
