The special mechanism of concrete mixer trucks mainly includes power take-off, front and rear brackets of mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc. Its working principle is to take out the power of the auto lattice through the power take-off device and drive the variable pump of the hydraulic system to convert the mechanical energy into hydraulic energy and transmit it to the quantitative motor. The motor then drives the reducer, which drives the mixing device to carry out concrete stir.

The domestic concrete mixer truck adopts the power take-off mode of the main vehicle machine. The function of the power take-off device is to take out the engine power by manipulating the power take-off switch and driving the mixing drum through the hydraulic system. The stirring drum rotates forward during the feeding and transportation process, to facilitate the feeding and mixing of the concrete. When discharging Reverse rotation, cut off the power connection with the engine after the work is finished.
The hydraulic system of the 6x4 concrete mixer truck converts the engine power taken out by the power take-off (usually a rear-mounted full-function power take-off) into hydraulic energy (displacement and pressure), and then output as mechanical energy (speed and torque) through the motor, to provide power for the rotation of the mixing drum.
1. The reduction mechanism of the concrete mixer truck decelerates the output speed of the motor in the hydraulic system and then transmits it to the mixing drum.
2. The operating mechanism of the concrete mixer truck controls the rotation direction of the mixing drum, so that it rotates forward during feeding and transportation, and rotates reversely during discharging.
3. The operating mechanism of the 8x4 concrete mixer truck controls the speed of the mixing drum.
The mixing device of the concrete mixer truck is substantially composed of a mixing barrel and its supplementary supporting corridor. The mixing barrel is a vessel for concrete, which is made of high-quality wear and tear-resistant thin sword plate. To be suitable to automatically load and discharge concrete, its inner wall is welded with special-structured helical blades. When turning, the concrete moves along the spiral direction of the blade, and is mixed and stirred during the nonstop lifting and turning process. During the feeding and transportation process, the mixing barrel rotates forward, and the concrete moves inward along the blades. When discharging, the mixing barrel reverses, and the concrete is discharged outward along the blades. The gyration of the mixing barrel is guaranteed by the hydraulic drive. A CNG concrete mixer truck with a loading capacity of 3 to 6 boxy measures generally uses a hydraulic pump driven by a machine through a power affair shaft. Also, the high-pressure oil painting drives the hydraulic motor to drive the mixing barrel, and the vehicle-mounted supplementary diesel machine drives the hydraulic pump to drive the hydraulic motor with a loading capacity of 9 to 12 boxy measures. The blade is the main part of the mixing device, damage or severe wear and tear will beget the concrete to mix inversely. In addition, if the angle of the blade isn't designed duly, it'll also beget isolation of the concrete.
The main function of the concrete mixer truck 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.
The fully enclosed device of the concrete mixer truck adopts rotary sealing technology, which seals the inlet and outlet of the concrete mixer truck. It solves a series of problems such as water evaporation, mortar layering, concrete material spilling, and driving safety in traditional mixer trucks.
