The push plate 52 will push the debris pressed into a cake to the left and move it out of the collection barrel 41. The pushed debris will push the revolving door 42 to open, and the pushed out debris will fall into the collection box 561. When the movable plate 422 moves downward, it will contact and hit the protrusion 563, which will drive the rotating plate 562 to rotate. The rotating plate 562 will push the debris in the collection box 561 to move to the left to prevent the debris from accumulating in one place, thereby affecting the collection amount of debris in the collection box 561.
