step three: the first motor (310) is started to drive the screw rod (312) to rotate, two thread sleeves (311) on the screw rod (312) are close to each other, the inclined rod (313) is made to be lengthened, the sliding plate (317) is pushed to slide downwards, the pulley (316) is made to contact with the ground to facilitate moving equipment, the push rod (412) is pulled, the push rod (412) is made to drive the wedge block (414) to slide in the second sliding rail (415), the inclined plate (410) is made to move up and down, and waste falling on the inclined plate (410) is led out quickly.
