The surface of the discharge port 1 is movably connected to the telescopic frame 318 through a bar groove. The surface of the discharge port 1 away from the adjustment plate 315 is installed with the other end of the telescopic frame 318. The telescopic frame 318 can be telescoped by the movement of the adjustment plate 315. A mounting plate 319 is fixedly connected to the telescopic frame 318, and a double-headed motor 12 is installed on the mounting plate 319. A slide groove 3110 is penetrated on the inner wall of the discharge chute 11, and a mounting block 3111 is movably connected inside the slide groove 3110. A folding groove is formed between the mounting block 3111 and the slide groove 3110.

The length of the bottom of the feed port 311 is the same as the width of the discharge chute 11. The limit strip 317 is made of plastic with good elasticity. The vertical cross-sectional dimension of the limit strip 317 is consistent with the dimension of the rectangular to strip-shaped portion of the feed port 311. Six groups of cloth plates 3120 are provided. The width of the cloth plates 3120 is the same as the thickness of the discharge chute 11. The cloth plates 3120 are made of rubber.

[0045] It is worth noting that the cylinder 3121 can push the moving block 314 to slide on the inner side of the connecting frame 316 when it works.
