Many friends have seen since the loading mixer. Of course, more and more friends have already owned the mixer, because it is true that the mixer can help us finish the work quickly by using it. However, when you are using the self loading mixer, we also suggest that you can understand the relevant composition of the mixer, so that when you are using the self loading mixer, you can understand the relevant composition of the mixer When loading the mixer, it will be more convenient.
Understand the composition of self loading mixer to help safe use and reduce hidden dangers
1、 Power take-off device
The power take-off mode of engine is adopted for the self loading mixer. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch. The mixing drum is driven by the hydraulic system. The stirring drum rotates forward in the process of feeding and transportation to facilitate the feeding and mixing of concrete. It rotates reversely when discharging, and cuts off the power connection with the engine after the end of the work.
2、 Hydraulic system
The engine power taken out by the power take-off device is converted into hydraulic energy (displacement and pressure), and then the motor outputs mechanical energy (speed and torque) to provide power for the rotation of the mixing drum.
After decelerating the speed of the motor output in the hydraulic system, it is transmitted to the mixing drum.
4、 Control mechanism
Control the rotation direction of the mixing drum from the loading mixer to make it rotate forward in the process of feeding and transportation, and reverse rotation when discharging. Control the speed of mixing drum.
5、 Mixing device
The self loading mixer is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a concrete loading container, which is made of high-quality wear-resistant thin steel plate. In order to automatically load and unload concrete, its inner wall is welded with spiral blades of special shape. When rotating, the concrete moves along the spiral direction of the blade, and is mixed and mixed in the process of continuous lifting and turning. In the process of feeding and transportation, the mixing drum rotates forward, and the concrete moves inward along the blade. When discharging, the mixing drum reverses and the concrete is discharged outward along the blade. The rotation of the mixing drum is ensured by the hydraulic driving device. The self loading mixer truck with a loading capacity of 3-6 cubic meters generally adopts the hydraulic pump driven by the automobile engine through the power output shaft, and then the mixing drum is driven by the hydraulic motor driven by the high-pressure oil, and the hydraulic motor is driven by the hydraulic pump driven by the vehicle auxiliary diesel engine when the loading capacity is 9-12 cubic meters. Blade is the main part of the mixing device, damage or serious wear will lead to uneven mixing of concrete. In addition, if the angle of blade is not reasonable, it will cause concrete segregation.
