howo 8×4 concrete mixer truck

mixer truck It is composed of automobile chassis, mixing drum, transmission system, water supply device, full-power power take-off, front and rear brackets of mixing drum, reducer, hydraulic transmission system, feeding and discharging system, control mechanism and other parts. Due to technical bottlenecks, domestically-made mixer trucks with a tank volume of 3m³-8m³ use four domestically-made parts, and most of the four major parts used for those with a volume of over 8m³ are imported parts.

The dedicated mechanism mainly includes power take-off, front and rear supports of the mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc. Its working principle: take out the power of the car chassis through the power take-off device, and drive the variable pump of the hydraulic system, convert the mechanical energy into hydraulic energy and transmit it to the fixed motor, and then the motor drives the reducer. The reducer drives the mixing device to carry out Stir.

The domestic concrete mixer truck adopts the power take-off method of the main vehicle engine. The function of the power take-off device is to take out the engine power by manipulating the power take-off switch, and drive the mixing drum through the hydraulic system. The agitating drum rotates in the forward direction during the feeding and transportation process to facilitate the feeding and mixing of the concrete. Reverse rotation, cut off the power connection with the engine after the end of the work.

The engine power taken out by the power take-off (usually a rear-mounted full-function power take-off) is converted into hydraulic energy (displacement and pressure), and then output by the motor as mechanical energy (speed and torque) to provide for the rotation of the mixer drum power.

After decelerating the output speed of the motor in the hydraulic system, it is transmitted to the mixing drum.

a. Control the direction of rotation of the mixing drum so that it rotates forward during feeding and transportation, and rotates backward during discharge.
b. Control the speed of the mixing drum.

The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used to mix dry materials during transportation. The cleaning system also cools the hydraulic system.

The fully enclosed device adopts rotary sealing technology to seal the inlet and outlet of the mixer truck, and solves the series of problems of traditional mixer trucks such as water evaporation, mortar layering, concrete spilling, and driving safety
