The outside of the two conveying augers 706 are respectively attached to the inner wall of the sorting cylinder 701 and the inner wall of the conveying cylinder 704. The screen 703 is arc-shaped, and the inner wall of the screen 703 is attached to the inner wall of the sorting cylinder 701.

[0031] The top of the crushing box 3 is equipped with a dust collection mechanism 8, which includes an exhaust channel 801, a fixed cylinder 802, a cross plate 803, a fan 804, a filter channel 805, a dust collection box 806, a dustproof net 807, and a feeding channel 808.

[0032] An exhaust duct 801 is provided at the top of the inner wall of the crushing box 3. A fixed cylinder 802 is equidistantly connected to the bottom of the exhaust duct 801 at the same position inside the crushing box 3.

[0034] The working principle and usage process of this utility model are as follows: First, the raw material is fed into the crushing box 3 through the feeding channel 808. Then, the rotary motor 6 is started to drive the crushing roller 4 to rotate. Through the cooperation of the transmission gear 5, the two crushing rollers 4 rotate relative to each other to crush the raw material. At the same time, the blower 804 is started to draw the dust generated during crushing into the exhaust channel 801 through the fixed cylinder 802. This forces the air to carry the dust into the filter channel 805 through the exhaust channel 801 and then out through the dust collection box 806 and the dustproof net 807. Thus, the dust in the air is blocked in the dust collection box 806 by the dustproof net 807, reducing the dust dispersion.

[0035] Next, the crushed raw material enters the sorting cylinder 701. With the cooperation of the screen 703, the completely crushed raw material passes through the baffle 702 and enters the conveying cylinder 704, while the incompletely crushed raw material is blocked inside the sorting cylinder 701. Then, through the cooperation of the drive wheel 709 and the drive belt 710, the power is transmitted, driving the rotating rod 705 and the conveying auger 706 inside the sorting cylinder 701 to rotate, pushing out the incompletely crushed raw material. At the same time, through the cooperation of the sprocket 707 and the chain 708, the rotating rod 705 inside the sorting cylinder 701 drives the rotating rod 705 and the conveying auger 706 inside the conveying cylinder 704 to rotate, pushing out the completely crushed raw material from the conveying cylinder 704.

[0036] Finally, the raw materials discharged from the sorting cylinder 701 and the conveying cylinder 704 are received by the guide box 9. Then, through the cooperation of the guide plate 10 and the discharge channel 11, the collected raw materials are discharged to both ends, which facilitates the collection of incompletely crushed raw materials for repeated crushing, while the completely crushed raw materials are sent to subsequent processing.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
