When the extrusion wheel 580 squeezes the force-bearing rod 560, the screen bucket 530 rises, driving the slider 520 to move, and stretching the reset spring 550. When the extrusion wheel 580 stops squeezing the force-bearing rod 560, the reset spring 550 resets the slider 520 to drive the screen bucket 530 to reset, thereby causing the screen bucket 530 to swing up and down, so as to screen the crushed waste and classify and collect the waste.
