When the vertical slide bar 802 moves, it pushes the corrugated baffle 803 on one side to shrink in corrugation and pulls the corrugated baffle 803 on the other side to extend. By arranging corrugated baffles 803 on both sides of the vertical slide bar 802 to cover and resist the top of the electric slide rail 801 at all times, A vertical slide bar 802 with a certain height is set to limit the distance between each storage shelf. After the goods are placed on the storage shelf, the electric push rod 911 drives the driving shaft to push the first guide rail 901. Since the first guide rail 901 is fixedly connected to the storage shelf, the electric push rod 911 will drive the second guide rail 912 to move upward. When the second guide rail 912 moves upward, it pulls the elliptical slide bar 1 904 and the elliptical slide bar 2 905 on the inner wall of the long slide groove 1 902 to slide in a cross shape. The second guide rail 912 drives the elliptical slide bar 1 904 and the elliptical slide bar 2 905 to slide relative to each other in a cross shape to block the two sides of the storage shelf. When the elliptical slide bar 1 904 and the elliptical slide bar 2 905 slide in the long slide groove 1 902,The push spring 908 pushes the square push plate 907 to push the elliptical slide bar 1 904 and the elliptical slide bar 2 905 through the push force. A T-shaped slide groove 1 903 is provided on the inner wall of the long slide groove 1 902 to slide and limit the square push plate 907 through the T-shaped slider 906. The square push plates 907 are provided at both ends of the elliptical slide bar 1 904 and the elliptical slide bar 2 905 to push them to slide synchronously. When the debris cleaned by the concave scraper 804 is pushed toward the side sealing device 9, it will contact the V-shaped baffle 910. The debris contacting the V-shaped baffle 910 will be affected by the thrust and move toward the two sides of the storage shelf close to the electric push rod 911 along the inclined surface of the V-shaped baffle 910 and be discharged.
