Do you know the device mechanism of the self loading mixer? Understanding this problem can make you get effective effect and good safety when using the mixer.
Power take-off device: the automatic feeding mixer adopts the power take-off mode of main engine. The function of the power take-off device is to take out the engine power by operating the power take-off switch and drive the mixing drum through the hydraulic system. Reverse rotation and disconnect the engine power supply after the work is completed.
Hydraulic system device: the engine power taken out by the power take-off (usually the rear full-function power take-off) is converted into hydraulic energy (displacement and pressure), and then output by the motor into mechanical energy (speed and torque) to provide power for the rotation of the mixing drum.
Reducer device: after decelerating the output speed of the motor in the hydraulic system, it is transmitted to the mixing drum.
Operation mechanism device: a device that controls the rotation direction of the mixing drum to make it rotate forward when feeding and reverse when discharging. Control the rotating speed of the mixing drum.
Cleaning system device: the main function of the cleaning system is to clean the mixing drum, and sometimes it is also used for dry material mixing during transportation. The cleaning system also cools the hydraulic system.
Closure device: the full closure device adopts rotary sealing technology to seal the inlet and outlet of the mixer truck, which solves a series of problems existing in the traditional mixer truck, such as water evaporation, mortar stratification, concrete scattering, driving safety and so on.
Mixing device: mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a concrete loading container. It is made of high-quality wear-resistant steel sheet. In order to automatically load and unload concrete, its inner wall is welded with special-shaped spiral blades. When rotating, the concrete moves along the spiral direction of the blade, and is mixed and stirred in the process of continuous lifting and overturning.
In the process of feeding and conveying, the mixing drum rotates forward and the concrete moves inward along the blade. During unloading, the mixing drum reverses and the concrete is discharged outward along the blade. The rotation of the mixing drum is guaranteed by the hydraulic driving device.
