The circumferential outer wall of the rubber sleeve 17 is slidably connected to the inner wall of the sludge hopper 7. When the sealing cover 15 moves above the sludge hopper 7, the sludge inside the body 1 can enter the sludge hopper 7. When the sealing cover 15 slides into the sludge hopper 7, the sludge inside the sludge hopper 7 is squeezed downward by the sealing cover 15. At this time, the sludge can be quickly discharged through the sewage discharge pipe 9, improving the self-sewage effect of the device.

[0021] As Figure 1 and Figure 2As shown in the figure, a working bridge 2 is installed on the top of the body 1. The working bridge 2 is located above the main shaft 3. A sludge scraping frame 4 and a support rod 5 are installed on the outer wall of the main shaft 3. A plurality of cables 6 are installed on the surface of the main shaft 3, and the plurality of cables 6 are respectively connected to the sludge scraping frame 4 and the support rod 5.

The bottom of the sludge scraping plate 18 is slidably connected to a telescopic plate 19. Two sliding rods 20 are fixedly arranged symmetrically on the top of the telescopic plate 19. The tops of the two sliding rods 20 penetrate through the sludge scraping plate 18 and are slidably connected thereto. Springs 21 are sleeved on the circumferential outer walls of the two sliding rods 20. One end of the spring 21 is fixedly connected to the sliding rod 20, and the other end of the spring 21 is fixedly connected to the sludge scraping plate 18. By driving the sludge scraping frame 4 to rotate through the main shaft 3, the sludge scraping frame 4 drives the sludge scraping plate 18 to move.

When the telescopic plate 19 contacts larger stones, the telescopic plate 19 slides upward, and the two sliding rods 20 slide upward, so that the spring 21 is stretched to protect the telescopic plate 19.

[0023] Working principle: By driving the cylindrical cam 11 to rotate through the main shaft 3, when the cylindrical cam 11 rotates, the cylindrical protrusion on the inner wall of the mounting plate 13 can slide along the inner wall of the circulation groove 12, so as to drive the sealing cover 15 to reciprocate up and down along the inner wall of the mud bucket 7, so that the sealing cover 15 moves above the mud bucket 7 and then slides downward into the mud bucket 7. When the sealing cover 15 moves, it can drive the guide rod 16 to slide up and down along the inner wall of the mounting plate 13;

[0024] By driving the sludge scraping frame 4 to rotate through the main shaft 3, the sludge scraping frame 4 drives the sludge scraping plate 18 to move. The sludge inside the body 1 is scraped by the telescopic plate 19 at the bottom of the sludge scraping plate 18, so that the sludge accumulates inside the mud bucket 7. When the telescopic plate 19 contacts larger stones, the telescopic plate 19 slides upward, and the two sliding rods 20 slide upward, so that the spring 21 is stretched to protect the telescopic plate 19;

[0025] When the sealing cover 15 moves above the mud bucket 7, the sludge inside the body 1 can enter the mud bucket 7. When the sealing cover 15 slides into the mud bucket 7, the sludge inside the mud bucket 7 is squeezed downward through the sealing cover 15. At this time, the sludge can be quickly discharged through the sewage discharge pipe 9, improving the self-sewage discharge effect of the device.
