Because the dust chain cover 53 is made of flexible material and folded into wrinkles, it can always keep the storage hopper 1 closed when the swing tube slide 51 is stretched or folded, so as to avoid dust. In order to facilitate the movement of the swing tube slide 51, a pulley 54 for sliding is provided at the bottom of the swing tube slide 51.

When the cylinder 72 pushes the swing arm 73 forward, The sprocket rotates clockwise, driving the driven sprocket 7-8 to rotate clockwise, thereby causing the inner drum 7-5 to rotate, causing the notch 7-7 to face the feed inlet 7-6, releasing the closed state, and allowing the material to be distributed; when the cylinder 72 retracts and pulls the swing arm 73, the sprocket rotates counterclockwise, driving the driven sprocket 7-8 to rotate counterclockwise, thereby causing the inner drum 7-5 to rotate, causing the notch 7-7 to change direction, releasing the open state, closing the fabric duckbill 3, and stopping distribution.

[0032] Reference Figure 5-Figure 6The lifting assembly 201 includes a movable bracket 21 connected to the lower hopper 2 and the fabric duckbill 3 assembly, and a fixed bracket 22 installed outside the movable bracket 21. The fixed bracket 22 is equipped with a driving chain shaft 24 driven by a lifting reduction motor 23. Both ends of the driving chain shaft 24 are equipped with lifting main sprockets 25. The lifting main sprocket 25 is connected to the driving sprocket 27 on the fixed bracket 22 through a transmission chain 26. A pulling piece 28 is provided on the movable bracket 21. The pulling piece 28 is connected to the driving sprocket 27 through a pulling chain 29. The pulling chain 29 is driven by a rotating The lifting and reducing motor 23 drives the driving chain shaft 24 to rotate, so that the lifting main sprocket 25 drives the transmission sprocket 27 to rotate through the transmission chain 26. After the transmission sprocket 27 rotates counterclockwise, the pulling piece 28 on the movable bracket 21 is lowered by pulling the chain 29, so that the movable bracket is lowered, and the combination of the lower hopper 2 and the material distribution duckbill 3 is lowered to start material distribution.
