When the third gear 210c rotates to drive the differential mechanism 210c-1 to rotate, the differential mechanism 210c-1 drives the third bevel gear set 330c-11 to rotate at a higher speed. The output end of the differential mechanism 210c-1 is connected with one end of the third bevel gear set 330c-11 away from the reciprocating screw rod 330c-1 through a rotating shaft.

[0068] In the embodiment, the specific working process is as follows: when the first gear 230a rotates to drive the belt pulley set 230a-2 to rotate, the second fan 310a-1 is driven to rotate rapidly, and when the second fan 310a-1 rotates, the residual waste in the scattered waste falling in the sorting box 310 is blown into the air outlet pipe 310b, and then enters the residual collection box 330a along with the airflow and is collected, while the metal waste falls from the inside of the sorting box 310 into the metal collection box 320 under the action of its own gravity and is collected, so as to realize the timely separation of the metal waste and the residual waste, facilitate the timely reuse of the recycled metal and the light residual waste, and at the same time, when the first scattering roller 220a rotates to drive the eccentric cam 210b to rotate, the eccentric cam 210b drives the third gear 210c to rotate intermittently, the third gear 210c drives the differential mechanism 210c-1 to rotate, the differential mechanism 210c-1 drives the third bevel gear set 330c-11 to rotate at a high speed, and then drives the reciprocating lead screw 330c-1 to rotate, so that the pressure assembly 330b completes one-time pressing and lifting under the limiting action of the limiting slide rod 330c-2, thereby intermittently pressing the residual pieces in the residual collection box 330a, so as to avoid that the residual pieces expand to cause insufficient collection capacity of the residual collection box 330a.

[0069] Embodiment 5

[0070] On the basis of the embodiment 4, in order to avoid that the pressure assembly 330b is stuck at the top during the pressing process because of the residual pieces on the top being introduced through the air outlet pipe 310b, the residual collection box 330a has a top rod 330a-2 on the inner wall bottom side, which is used to abut against one side of the pressure plate 330b-2 when the pressure plate 330b-2 is lifted to a certain height, so that the pressure plate 330b-2 is inclined, thereby facilitating the pressure plate 330b-2 to dump the residual pieces on the top; Figures 6-7

[0071] The pressure assembly 330b comprises a pressure frame 330b-1 which is screwed on one end of the reciprocating lead screw 330c-1 and slidably connected on the other end of the limiting slide rod 330c-2, and a pressure plate 330b-2 which is movably connected with the pressure frame 330b-1, the pressure frame 330b-1 is used to movably install the pressure plate 330b-2 and press the residual pieces in the residual collection box 330a in cooperation with the pressure plate 330b-2, and the pressure plate 330b-2 is used to press the residual pieces downward;

[0072] ​The inner wall of the pressing frame 330b-1 has a connecting hole 330b-11 on both sides, which is used to connect with the connecting rod 330b-21 to make the pressing plate 330b-2 movably connected with the pressing frame 330b-1. The pressing plate 330b-2 has a connecting rod 330b-21 on both sides, which extends into the connecting hole 330b-11. The outer wall of the connecting rod 330b-21 has a torsion spring, the other end of which is connected with the inner wall of the connecting hole 330b-11. The torsion spring is used to facilitate the pressing plate 330b-2 to return to the parallel state with the pressing frame 330b-1 under the torsion of the torsion spring after the top rod 330a-2 is separated from the pressing plate 330b-2, so as to press the residual parts in the residual collection box 330a more firmly. At the same time, the slight vibration generated after the pressing plate 330b-2 returns to the original state shakes off the residual parts on the top of the pressing frame 330b-1.

[0073] In this embodiment, the specific working process is as follows: when the reciprocating wire rod 330c-1 rotates, it drives the pressing frame 330b-1 and the pressing plate 330b-2 to move downward. When the top of the pressing plate 330b-2 is separated from the bottom of the top rod 330a-2, the pressing plate 330b-2 returns to the parallel state with the pressing frame 330b-1 under the action of the torsion spring. With the continuous pressing of the pressing frame 330b-1 and the pressing plate 330b-2, the residual parts that have just entered the residual collection box 330a are timely pressed. When the pressing frame 330b-1 descends to a certain position, it begins to rise until the top of the pressing plate 330b-2 contacts the bottom of the top rod 330a-2 again. At this time, the pressing plate 330b-2 begins to overturn, thereby dumping the residual parts that have just been mistakenly contacted on the top of the pressing plate 330b-2 to the inner wall bottom of the residual collection box 330a.
