[0025] Reference Figure 1-Figure 5 The utility model provides a structure for preventing the nozzle of a pipe in a desludging machine from being blocked, comprising a desludging machine housing 1 and a plurality of support frames 2 fixed to an inner wall of one side of the desludging machine housing 1 by bolts, a plurality of support frames 2 having mounting holes 10 on the tops thereof and water pipes 3 fixed thereto by clamps, a plurality of nozzles 5 being arranged on one side of the water pipes 3, one end of the water pipes 3 passing through the desludging machine housing 1 and welded with a connecting flange 6, so as to facilitate communication with an external pipeline, a vertical bearing seat 9 being fixed to the tops of the plurality of support frames 2 by bolts, a connecting rod 4 being arranged in the vertical bearing seat 9, a driving component for driving the connecting rod 4 to flip being arranged on an outer wall of one side of the desludging machine housing 1, the driving component being a reduction motor 7, one end of an output shaft of the reduction motor 7 passing through the desludging machine housing 1 and being fixed to the connecting rod 4 by a coupling, 7 rotates and drives the connecting rod 4 to rotate slowly. A plurality of arc-shaped rods 8 are fixed to the outer side of the circumference of the connecting rod 4 by bolts. A fixing seat 13 is welded to the end of the arc-shaped rod 8. A clearing assembly for cleaning the inside of the nozzle 5 is arranged in the fixing seat 13. The filter cloth in the desludging machine is washed by spraying medium water through the nozzle 5, and the arc-shaped rod 8 and the clearing assembly are away from the nozzle 5 and avoid the position, so as to avoid affecting the nozzle 5. When clearing is required, the connecting rod 4 drives the arc-shaped rod 8 to flip through the driving component, and the clearing assembly arranged on the fixing seat 13 at the end of the arc-shaped rod 8 is inserted into the nozzle of the nozzle 5, and the cleaning operation is performed, so as to avoid the nozzle 5 being blocked easily due to the medium water containing certain impurities, thereby affecting the medium water washing efficiency. The plurality of fixing seats 13 correspond to the plurality of nozzles 5 one by one.

[0026] The clearing assembly in the utility model includes a servo motor 11, which is fixed to the end of a fixing seat 13 by bolts. One end of the output shaft of the servo motor 11 passes through the fixing seat 13 and is welded with a rotating shaft 14. A plurality of rubber columns 15 are bonded to the outer circumference of the rotating shaft 14. The plurality of rubber columns 15 are arranged at an inclined angle, and the end direction of the rubber column 15 is away from the end of the rotating shaft 14. Due to the material characteristics of the rubber column 15, the rotating shaft 14 is deformed when it is rotated and inserted into the nozzle of the nozzle 5, so that the rubber column 15 is in full contact with the inner wall of the nozzle. Then, the servo motor 11 rotates to make the rotating shaft 14 drive the rubber column 15 to rotate and perform cleaning operations. A shield 12 is fixed to the end of the fixing seat 13 by bolts, and the shield 12 covers the servo motor 11, so that the shield 12 shields and protects the servo motor 11.

[0032] S4: The material characteristics of the rubber column 15 cause the shaft 14 to deform when it is rotated and inserted into the nozzle of the nozzle 5, so that the rubber column 15 is fully in contact with the inner wall of the nozzle. Then, the servo motor 11 rotates to make the shaft 14 drive the rubber column 15 to rotate and perform the cleaning operation.
