Cement mixer works
Cement mixer works and accessories Cement mixer trucks are also called concrete mixer trucks and concrete mixer trucks. They are mainly used for the transportation of cement in concrete mixing plants. Dongfeng Cement Mixer and Howo Cement Mixer are common. The following describes the cement mixer accessories and working principle. 1. Power take-off system The domestic concrete mixer truck uses a chassis engine to take power. The function of the power take-off device is to take out the engine power through a full-power driver and drive the mixing drum through the hydraulic system. The mixing drum rotates forward during the feeding and transport process to facilitate the feeding and stirring of the concrete. When the material is discharged, it is reversed. Rotate and cut off the power connection with the engine after the job is over. 2. Hydraulic system The main function of the hydraulic system is to convert the power of the power takeoff into hydraulic energy (displacement and pressure), and then output by the motor as mechanical energy (speed and torque) to provide power for rotation of the mixer drum. 4. Control mechanism 5. Stirring system The stirring device consists of a mixing drum and its auxiliary support components. The mixing drum is a concrete loading container, and the concrete moves in the direction of the spiral of the blades as it rotates, and is subjected to mixing and stirring during continuous lifting and turning. During feeding and transportation, the mixing drum rotates forward and the concrete moves inward along the blades. When the material is discharged, the mixing drum is reversed and the concrete is discharged outward along the blades. The blade is the core component of the stirring device. Damage or serious wear will cause uneven mixing of the concrete. In addition, if the angle of the blade is unreasonable, it will cause the concrete to segregate. 6. Cleaning system The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used to dry the drum during transportation. The cleaning system also cools the hydraulic system. 7. Heat Dissipation System The heat dissipating system uses high-temperature circulating oil to the hydraulic pump. The heat generated during the working process of the hydraulic motor is dissipated through the heat sink and the fan to avoid the high temperature causing damage to the hydraulic system and malfunction. The mixing volume of cement mixers is different. Different manufacturers and different chassis will lead to differences in the use of mixer accessories and layout. But the working principle is the same.

Cement mixer main accessories include power take-off, front and rear brackets, mixer, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system and so on. The working principle is that the power of the automobile chassis is taken out through the power takeoff device, and the hydraulic pump of the hydraulic system is driven to convert the mechanical energy into hydraulic energy and transmitted to the hydraulic motor. The motor then drives the speed reducer, and the speed reducer drives the stirring system to perform the concrete work. Stir.
3. The speed reducer decelerates the output speed of the hydraulic motor and transmits it to the mixing drum.
4.1 The direction of rotation of the mixer is controlled so that it rotates in the forward direction during feeding and transport, and rotates in reverse when discharging.
4.2 Control the speed of the mixer drum.
