[0052] A hose 569 is fixedly arranged at the bottom of the discharge pipe 568 .

[0053] Working principle: first, the material is put into the feed hopper 4, and then reaches the top of the crushing frame 51 through the feed hopper 4, and then falls to the top of the multiple crushing rollers 511, driving the first motor, thereby driving the multiple second gears 513 to rotate, and then driving the multiple crushing rollers 511 to rotate, and then through the cooperation of the rotation of the multiple crushing rollers 511, the preliminary crushing of the material is achieved. At this time, the crushed material falls to the top of the screening plate 52, and the smaller particles will fall downward through the first screening hole, and the unqualified ones will stay on the top of the screening plate 52, further driving the double-axis motor, thereby driving the second bevel gear 535 to rotate, and then driving the first bevel gear 533 to rotate, and then driving the two-way lead screw 53 to rotate, and then driving the threaded seat 532 to move, and then driving the connecting rod 523 to move, and then driving the cross bar 522 to move, and then driving the push plate 521 to move, and through the push plate 521 to move to the right, thereby pushing the unqualified materials to move to the right, and reach the collecting seat 54 through the feed chute. The material on the top of the second movable plate 544 moves upward. When the second movable plate 544 is higher than the crushing frame 51, the second electric telescopic rod 547 is driven to contract, thereby driving the movable block 548 to move, and the second movable plate 544 rotates. At this time, the left side is lower than the right side, and the material on the top of the second movable plate 544 rolls to the left, and further rolls into the crushing frame 51. The above operation is repeated until it falls downward through the first screening hole. The first electric telescopic rod 538 is driven, thereby driving the third mounting block 539 to move backward, thereby driving the U-shaped seat 534 to move backward, thereby driving the second bevel gear 535 to move backward, thereby making the second bevel gear 535 on the rear side mesh with the third bevel gear 536. At this time, the second bevel gear 535 drives the third bevel gear 536 to rotate, thereby driving the second pulley 519 to rotate, and the first belt drives the first pulley 518 to rotate, thereby driving the threaded rod 517 to rotate. Since the left and right ends of the threaded rod 517 are provided with threaded sections with opposite rotation directions, the two first sealing plates 516 are driven to move until the two first sealing plates 516 contact each other, thereby achieving sealing of the bottom end of the crushing frame 51.
