The larger materials slide into the inside of the collection box 210 through the guide plate 108. Secondly, the output end of the stepper motor 204 drives the first screw rod 202 to rotate, so that the lifting frame 205 moves upward, driving the collection box 210 to move to a position higher than the crushing box 11. 0, and then the output end of the servo motor 208 drives the second screw rod 206 to rotate, so that the movable plate 209 moves, and drives the collecting box 210 to move towards the direction close to the crushing box 110. Finally, the output end of the second electric push rod 214 retracts, drives the cover 213 to move to the right, opens the discharge port of the discharge frame 212, and starts the conveyor belt 211 inside the collecting box 210, so that the larger particles of material inside the collecting box 210 pass through the discharge port of the discharge frame 212 and fall into the crushing box 110 for crushing until the size of the material meets the qualified size and meets the needs of the staff.
