At the construction site, the mixing system of the concrete mixer truck is a very important link. The quality of a truck of concrete is closely related to the mixing system. For many people who are not familiar with the mixer truck, knowing the mixing system first will make us get twice the result with half the effort.
In fact, the small concrete mixer should be composed of the mixing drum and its auxiliary supporting parts. The mixing drum of the mixer truck is a concrete loading container, which is made of high-quality wear-resistant steel sheet. In order to realize the automatic loading and unloading of concrete, the inner wall is welded with spiral blades of special shape.
When the concrete mixer is rotated, the concrete moves along the spiral direction of the blade and is mixed in the continuous lifting process. During feeding and discharging, the mixing drum rotates forward, and the concrete moves inward along the blades. During discharging, the mixing drum reverses, and the concrete is discharged outward along the blades. The rotation of the agitator is ensured by the hydraulic transmission device.
3-6 cubic meters concrete mixer truck is loaded. Generally, the truck engine drives the hydraulic pump through the power output shaft, and then uses high-pressure oil to drive the hydraulic motor and the mixing drum.
When the loading capacity of the hybrid vehicle is 2-5 cubic meters, the on-board auxiliary diesel vehicle drives the hydraulic pump to drive the hydraulic motor. The blade is the main part of the mixer truck. If it is damaged or severely worn, it will cause uneven mixing. In addition, if the design of blade angle is unreasonable, the concrete will be separated.
The control system is the control part of the whole mixer truck. The control panel is provided with an "I-shaped" slot, which is the active space of the control lever; And a limit hole is opened on the groove of the rear half to fix the position of the control lever. The control system controls the forward, reverse and rotational speed of the mixing drum through the left and right control levers at the rear of the vehicle, so as to complete the feeding and discharging and mixing actions.
The water supply system of the concrete mixer is mainly used to clean the mixing device. There are two types of water supply system for this vehicle, one is centrifugal water pump water supply system; One is the pressure water tank water supply system, which can be selected by users.
The concrete mixer will always keep the mixing drum rotating during transportation to ensure that the concrete carried will not solidify. After the concrete is transported, the interior of the mixing drum is usually washed with water to prevent the hardened concrete from occupying the space and make the volume of the mixing drum less and less.
