The rear end of the outer peripheral wall of the driving shaft 122 is fixedly sleeved with the second pulley 123. The first pulley 121 and the second pulley 123 are movably connected through the first belt 124. The back of the crushing bin 2 and below the second pulley 123 is rotatably mounted with a third pulley 125. The third pulley 125 and the second pulley 123 are movably connected through the second belt 126.

[0023] The gear transmission mechanism 11 includes a driving gear 111, a driven gear 112 and a gear box 113. The driving gear 111 is provided on the back of the middle crushing roller 7, and the backs of the left and right crushing rollers 7 are both provided with driven gears 112. The driving gear 111 is meshed with the driven gear 112, and a gear box 113 is provided outside the driving gear 111 and the driven gear 112.

[0024] Specifically, the driving motor 5 is started to rotate the first pulley 121, and the first pulley 121 transmits power to the second pulley 123 through the first belt 124. The second pulley 123 drives the middle crushing roller 7 to rotate. When the middle crushing roller 7 rotates, it will rotate with the driving gear 111. The driving gear 111 transmits power to the driven gears 112 on both sides, so that the crushing rollers 7 on both sides rotate synchronously.

The outer peripheral wall of the reciprocating screw 84 is threadedly connected to a threaded slider 85 with one end fixedly connected to the bottom of the sliding plate 82.

[0027] Specifically, when the intermediate crushing roller 7 rotates, it will drive the fifth pulley 103 to rotate. The fifth pulley 103 transmits power to the fourth pulley 102 through the third belt 104. The fourth pulley 102 drives the reciprocating screw 84 to rotate through the connecting shaft 101. The reciprocating screw 84 drives the threaded slider 85 to carry the brush 83 fixed on the sliding plate 82 to brush the mesh of the filter 6 back and forth, which can effectively prevent the filter 6 from being blocked.

[0028] In this embodiment, the discharging mechanism 9 includes an inclined plate 901, an auger cylinder 902, an auger shaft 903, an auger piece 904 and a discharging pipe 905.

[0029] Specifically, the crushed material passes through the filter screen 6 and falls onto the inclined plate 901, slides from the inclined plate 901 and accumulates on the auger cylinder 902. When the middle crushing roller 7 rotates, it will rotate with the second pulley 123. The second pulley 123 transmits power to the third pulley 125 through the second belt 126. The third pulley 125 transmits power to the auger shaft 903.
