Configuration of mixer truck
1. Power take-off
The domestic concrete mixer truck adopts chassis engine to take power. The function of the power take-off device is to take out the engine power through the full-power driver, and drive the mixing drum hydraulically. The mixing drum is in the forward direction during the feeding and transportation to facilitate the feeding and mixing of concrete, and in the reverse direction during the discharging, and cut off the power connection with the engine after the end of the work.
The main function of hydraulic pressure is to convert the power of the power take-off into hydraulic energy (displacement and pressure), and then output it into mechanical energy (speed and torque) through the motor to provide power for the rotation of the mixing drum.
Reduce the speed output by the hydraulic motor and send it to the mixing drum.
4. Control mechanism
4.1 Control the direction of the mixing drum so that it is in the forward direction during feeding and transportation, and in the reverse direction during discharging.
4.2 Control the speed of mixing drum.
The mixing device is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is the loading container for concrete. When rotating, the concrete moves along the spiral direction of the blade, and is mixed and mixed in the continuous mixing. During feeding and transportation, the mixing drum rotates forward and the concrete moves inward along the blade. When discharging, the mixing drum reverses and the concrete is discharged outward along the blade. The blade is the core part of the mixing device. Damage or serious wear will cause uneven concrete mixing. In addition, if the blade angle is not designed properly, it will also cause segregation of concrete.
The main function of cleaning is to clean the mixing drum, sometimes also used for dry material mixing drum during transportation. Cleaning also cools the hydraulic pressure.
7. Heat dissipation
High temperature circulating oil is used to heat the hydraulic pump. The heat generated by the hydraulic motor during operation is dissipated through the radiator and fan to avoid hydraulic damage and abnormal operation caused by high temperature.
