[0036] Please refer to Figure 1 , Figure 3 and Figure 5The top end of each of the two discharge boxes 2 is slidably connected with a butt joint pipe 202. By arranging the butt joint pipe 202, the height of the butt joint pipe 202 can be adjusted, so that the device is applicable to butt joint with discharge outlets of different heights, the generation of dust is further reduced, and the environmental protection capability is improved. One side of each of the two discharge boxes 2 is provided with a hydraulic rod 7. The output end of each of the two hydraulic rods 7 is fixedly connected with the butt joint pipe 202 close to the hydraulic rod 7. By arranging the hydraulic rod 7, the height of the butt joint pipe 202 can be accurately adjusted to adapt to discharge outlets of different heights, so that the flexibility and practicability of the device are further improved. The top end of each of the two butt joint pipes 202 is funnel-shaped. By arranging the funnel-shaped design, the butt joint pipes 202 can more effectively receive materials from the discharge outlets, reduce the scattering and splashing of the materials during butt joint, and further reduce the generation of dust.

[0037] Please refer to Figure 1 、 Figure 3 and Figure 5 A driving assembly 3 is arranged between the two discharge boxes 2. The driving assembly 3 comprises two connecting frames 301. The two ends of each of the two connecting frames 301 are fixedly connected with one side of the discharge box 2 close to the connecting frame 301. A lead screw 302 is rotatably connected in each of the two connecting frames 301. A synchronous frame 303 is threadedly connected to the outer surface of each of the two lead screws 302. The two ends of each of the two synchronous frames 303 are fixedly connected with the extension pipe 201 close to the synchronous frame 303. By rotating the lead screw 302, the synchronous frame 303 can extend out of the discharge box 2 with the extension pipe 201 fixedly connected with the synchronous frame 303.
