(1) Control the rotation direction of the mixing drum to make it rotate forward in the process of feeding and transportation, and reverse rotation during unloading.
(2) Control the speed of mixing drum.
The mixing device is mainly composed of mixing drum and its auxiliary supporting components. The 4-square self loading mixer is a container for loading concrete. When rotating, the concrete moves along the spiral direction of the blade and is mixed and mixed during continuous lifting and rotation. During feeding and transportation, the mixing drum rotates forward and the concrete moves inward along the blades. When discharged, the mixing drum reverses and the concrete is discharged outward along the blades.
Blade is the main part of the mixer, damage or serious wear will lead to uneven mixing of concrete. In addition, if the blade angle is not reasonable, it will lead to concrete separation.
The main function of the cleaning system is to clean the mixing drum, sometimes drying the mixing drum during transportation. The cleaning system also cools the hydraulic system.
The rotary sealing technology is used to seal the inlet and outlet of the mixer, which solves the problems of water evaporation, mortar stratification, material overflow, driving safety and so on.
Influence of sludge on 4-square self feeding mixer
The 4-party self feeding mixer is usually used in the construction industry, and sludge cannot be avoided when it is used. This is how the sludge affects it.
1. The engine exhaust emission is reduced, and the service life of spark plug, oxygen sensor and three-way catalyst is also shortened.
2. The engine power is reduced, the acceleration is not stable, and the fuel consumption is increased.
3. It is very difficult to start the mixer truck. The idle speed of the cold car cannot reach the specified speed. In severe cases, the idle speed of the cold car will be turned off, and the idle speed after the hot car will be low.
4. Carbon deposition will also cause the piston ring of the engine to jam and affect the sealing performance of the piston ring. The fuel consumption of the mixer will increase, resulting in the engine burning oil and shortening the service life of the engine.
