[0022] As Figure 2 and Figure 3As shown in the figure, the feeding mechanism 6 includes a feeding pipeline 601 fixedly installed at the lower end of the bin 1. One side of the feeding pipeline 601 is fixedly installed with a mechanism housing 604. One side of the mechanism housing 604 is fixedly installed with a driving motor 606. The output end of the driving motor 606 is fixedly installed with a driving shaft 605. A squeezing screw 602 is arranged in the feeding pipeline 601. The feeding pipeline 601 is provided with a feeding port 603. The feeding pipeline 601 is connected to the lower end of the bin 1 through the feeding port 603.

[0023] Specifically, the driving motor 606 can drive the driving shaft 605 to rotate. After the driving shaft 605 rotates, it will drive the squeezing screw 602 to rotate in the feeding pipeline 601. When the squeezing screw 602 rotates in the feeding pipeline 601, it will drive the material to move forward along the feeding pipeline 601, so as to convey the material in the bin to the conveying belt 5 of the belt constant - quantity feeder 4.

[0024] As Figure 2 and Figure 4 As shown in the figure, the dust removal mechanism 7 includes a positioning frame body 701 fixedly installed at the bottom of the bin 1.

At the same time, the water sprayed out through the nozzle 702 will be caught by the water receiving tank 703, so as to recycle the water and reduce the waste of water resources.
