If the ore falls from above, it will hit the cover plate 17 inclined in the second chute 13. The cover plate 17 is inclined (refer to the figure in the specification). Figure 1 ), at this time, the ore hits the cover plate 17 and falls into the discharge box 12 for repacking. When the coal miner finishes packing, he pulls the pull plate 19 to drive the cover plate 17 to move. When the cover plate 17 is pulled, the shaft 18 will first enter the side slide groove 14 and then enter the circular groove 15. At this time, the cover plate 17 can be rotated in the circular groove 15 by the shaft 18, and the cover plate 17 changes from sliding to deflection. The end of the cover plate 17 is inserted into the fixed groove 16. At this time, the end of the cover plate 17 will push the end of the fixing rod 24 and move the fixing rod 24 inward. At this time, the fixing rod 24 is on the side of the end of the cover plate 17 and is pushed by the elastic member 26. At the same time, after the end of the cover plate 17 moves to the top, the fixing rod 24 will enter the fixing groove 16 and then enter the slot 21, fix the cover plate 17 on the discharge box 12, and seal the discharge box 12 to prevent the ore from falling off during transportation.
