[0035] In this embodiment, the collection box 13 can collect the debris discharged from the collection groove 5. The collection box 13 can be opened through the opening and closing plate 14. When the material pushing member works, it can push the debris inside the collection box 13 out. The opening and closing plate 14 can be limited through the limiting member to prevent the opening and closing plate 14 from being displaced under the influence of external force. The collection box 13 can be driven to move through the plurality of moving wheels 15.

[0036] Further, the pusher includes an electric push rod 16, a push plate 17 and an upper baffle 18.

The transmission rod 7 drives the two gears 8 to rotate. The two gears 8 drive the two tooth blocks 9 to slide in the workbench 1. The two tooth blocks 9 drive the connecting frame 10 to move towards the side close to the collection box 13. At the same time, the two sliding cylinders 12 slide on the two sliding rods 11 to guide the connecting frame 10, thereby driving the collection groove 5 to move towards the side close to the collection box 13. Until the collection groove 5 moves to a preset position, start the first driving member 3. The first driving member 3 works to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the collection groove 5 to rotate. When the collection groove 5 is tilted, the debris in the collection groove 5 is discharged into the collection box 13 for collection. After all the debris in the collection groove 5 is discharged, the second driving member 6 reversely drives the collection groove 5 to reset. At this time, the collection box 13 can be pulled out towards the side away from the workbench 1. The collection box 13 is driven to move by the multiple moving wheels 15. When the collection box 13 moves to the discharging point, pull the pull rod 21 towards the side away from the collection box 13 until the fixing rod 19 moves out of the collection box 13. Then pull the opening and closing plate 14 to open towards the side away from the collection box 13. Start the electric push rod 16. The electric push rod 16 works to drive the pushing plate 17 to move. The debris in the collection box 13 is discharged towards the side away from the collection box 13 through the pushing plate 17.
