[0025] When cleaning sludge, the utility model can control the driving mechanism so that the sludge pump 7 in the mobile box 6 slides along the length direction of the horizontal frame 1, thereby realizing automatic cleaning of the sludge in the area, and the cleaned sludge can be collected in the collecting box 10. The operation is simple and efficient, avoiding affecting the surrounding environment and also avoiding affecting the road width and thus affecting the passage of vehicles.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that the driving mechanism includes a driving motor 3 installed at one end of the horizontal frame 1 and a screw 2 that drives the mobile box 6 to slide on the horizontal frame 1. For example, the screw 2 is directly threadedly connected to the mobile box 6, or the screw 2 is indirectly threadedly connected to the mobile box 6, and then the mobile box 6 can be driven to slide on the horizontal frame 1 through the rotation of the screw 2. Both ends of the screw 2 are rotatably connected to the horizontal frame 1 to ensure the stability of the screw 2, and one end of the screw 2 is connected to the motor shaft of the driving motor 3. In practice, turning on the driving motor 3 can drive the mobile box 6 to slide on the horizontal frame 1.

[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that a nut 4 is threadedly connected to the screw rod 2 to achieve stable thread matching. The nut 4 is detachably connected to the mobile box 6 through an insertion mechanism, and then the nut 4 can be driven to move by the screw rod 2, and the nut 4 drives the mobile box 6 to move. At the same time, the equipment can also be disassembled and assembled, which is convenient for equipment assembly and subsequent maintenance.

[0029] It should be further explained that, preferably, a handle 13 is installed on the moving box 6, and the handle 13 is U-shaped to facilitate the manipulation of the moving box 6 for lifting.

[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that an arc groove is opened at the bottom of the movable box 6, the nut 4 is matched and arranged in the arc groove, and the plug block 16 is connected to the top wall of the arc groove. The structure is compact, and the two sides of the movable box 6 can be respectively in contact with the inner walls on both sides of the horizontal frame 1, so as to ensure the stability of the movable box 6 when sliding.

[0031] As a preferred implementation scheme in this embodiment, it needs to be further explained that a limit rod 5 extending along the length direction of the horizontal frame 1 is fixed in the horizontal frame 1, the limit rod 5 and the screw rod 2 are parallel to each other, and the limit rod 5 passes through the nut 4, so that the nut 4 can be prevented from rotating. When the screw rod 2 rotates, the nut 4 slides stably along the limit rod 5, thereby driving the moving box 6 to slide stably.

[0032] As a preferred implementation scheme in this embodiment, it needs to be further explained that the upper end of the movable box 6 is connected to the collecting box 10 through a support plate 19, and a drainage net 11 is arranged in the collecting box 10. The drainage net 11 is arranged obliquely, and an empty water gap is preferably reserved between the drainage net 11 and the inner bottom surface of the collecting box 10; a drainage pipe 12 is installed at the bottom of the collecting box 10. In practice, the water mixed in the sludge can be discharged through the drainage net 11 to reduce the load-bearing capacity of the device.

Therefore, under normal circumstances, the stability of the mobile box 6 on the transverse frame 1 can be enhanced.

In the natural state, the limit block 18 is slidably connected to the horizontal part of the cross frame 1. When the moving box 6 needs to be removed, the limit block 18 can be squeezed so that the limit block 18 enters the vertical part of the limit groove 14, and then the moving box 6 can be lifted to realize the removal of the moving box 6. The structure is simple and practical.
