Description
Technical Field

[0002] The sorting chamber is one of the important modules of the intelligent dry sorting machine. The sorting chamber is the place where the intelligent dry sorting machine collects materials after sorting the gangue. It is in the last link of gangue sorting. After the gangue is blown out and separated by the blowing nozzle, it will hit the rear side wall and top wall of the sorting chamber, among which the rear side wall and top wall are most seriously impacted by the materials.
[0003] In the prior art, the mainstream of intelligent sorting machine sorting chambers are arc top cover type and square reinforced type. Although the arc on the arc top cover type can reduce the impact of some materials, the rigidity of the arc top is particularly poor, it is easy to deform, and the arc top is difficult to process and weld, and the production cost is high; Figure 1 As shown, the square reinforced type mainly relies on the shock-absorbing pad inside the sorting chamber to resist the impact of coal gangue, but in the actual operation of the equipment, it is found that the sorting chamber of this type has high noise and high dust pollution environment, and the shock-absorbing pad is easily damaged in the long-term impact. If it is not replaced in time, the shock-absorbing pad will fall off, which will cause the internal structure of the sorting chamber to be destroyed. In severe cases, it will damage the lead plate of the sorting chamber, causing radiation leakage and causing production safety accidents. Therefore, it is urgent to study a sorting chamber of a coal intelligent dry sorting machine to solve the above problems. Utility Model Content
