The domestic concrete mixer truck adopts the power take-off mode of the main truck 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. The mixing drum rotates forward during feeding and transportation to facilitate feeding and mixing of concrete. It rotates reversely during discharging and cuts off the power connection with the engine after the work is completed.
Hydraulic system
The engine power taken out by the power takeoff is converted into hydraulic energy (displacement and pressure), and then output into mechanical energy (speed and torque) by the motor to provide power for the rotation of the mixing drum.
Reducer
The speed output by the motor in the hydraulic system is reduced and transmitted to the mixing drum.
Operating mechanism
(1) Control the rotation direction of the mixing drum to make it rotate forward during feeding and transportation and reverse
during discharging.
(2) Control the rotating speed of the mixing drum.
Mixing device of mixer truck
The mixing device is mainly composed of a mixing drum and its auxiliary supporting parts. The mixing drum is a container for loading concrete. When rotating, the concrete moves along the spiral direction of the blade, and is mixed and stirred in the process of continuous lifting and turning. During feeding and transportation, the mixing drum rotates forward, and the concrete moves inward along the blades. During discharging, the mixing drum reverses, and the concrete is discharged outward along the blades.
The blade is the main component in the mixing device. Damage or serious wear will lead to uneven mixing of concrete. In addition, if the design of blade angle is unreasonable, the concrete will be separated.
Cleaning system
The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used for dry material mixing drum during transportation. The cleaning system also cools the hydraulic system.
Closing device
The fully enclosed device adopts the rotary sealing technology to seal the inlet and outlet of the mixer truck, and solves a series of problems such as water evaporation of the traditional mixer truck, mortar layering, concrete scattering, driving safety, etc.
