On the side where the two inclined rods 26 are close to each other, there is a strengthening rod 27 fixedly connected. On one side of the inclined rod 26, there is a guide roller 28 rotatably connected. The lower end of the winding mechanism 2 is fixedly connected to the left side of the upper end of the hull 1. The outer wall of the collection bin 3 is embedded and connected to the upper right side of the hull 1.

[0024] Please refer to Figure 2 , in order to quickly adjust the angle of the conveying pipeline 71, the upper end of the fixed shell 21 is fixedly connected to the lower end of the support frame 22. The front end of the support frame 22 is bolted to the rear end of the motor 23. The inclined rod 26 is arranged at an inclined angle and is located above the right side of the hull 1.

[0025] Please refer to Figure 3 , in order to quickly convey the silt into the collection bin 3 through the spiral blade 710, the conveying mechanism 7 includes a conveying pipeline 71. The lower end of the conveying pipeline 71 is fixedly connected to the upper end of the hinge seat 6. On the left side of the lower end of the conveying pipeline 71, there is an outlet 72. On the left side of the conveying pipeline 71, there is a motor 73. The output shaft of the motor 73 is drivingly connected to a rotating shaft 74. On the outer wall of the rotating shaft 74, there is a screw blade 75 fixedly connected. On the outer wall of the rotating shaft 74, there is a screw blade 76 fixedly connected. On one side of the conveying pipeline 71, there is a semi-cylindrical barrel 77 fixedly connected. At the rear end of the semi-cylindrical barrel 77, there is a motor 78 detachably connected. The output shaft of the motor 78 is drivingly connected to a rotating shaft 79. On the outer wall of the rotating shaft 79, there is a spiral blade 710 fixedly connected. Through the setting of the spiral blade 710, it is convenient to convey the silt. On the outer wall of the rotating shaft 79, there is an installation rod 711 fixedly connected. Through the installation rod 711, a shovel tooth 712 is arranged. Through the shovel tooth 712, the silt is shoveled up. One end of the installation rod 711 is fixedly connected to the shovel tooth 712. One end of the semi-cylindrical barrel 77 is fixedly connected to a shovel 713. The left side of the lower end of the conveying pipeline 71 is in through connection with the upper end of the outlet 72. One side of the conveying pipeline 71 is detachably connected to one side of the motor 78. The outer diameters of the screw blade 75 and the screw blade 76 are the same as and adapted to the inner diameter of the conveying pipeline 71.

[0026] Working principle: First, the mounting rods 711 are arranged equidistantly on the second rotating shaft 79, and the length of the mounting rod 711 is greater than the radius of the spiral blade 710. A shovel 713 is provided at the lower end of the semi-cylindrical barrel 77. A reinforcing rod 27 is provided between the upper part of the semi-cylindrical barrel 77 and the conveying pipeline 71, strengthening the stability between the conveying pipeline 71 and the semi-cylindrical barrel 77. Then, the first rotating shaft 74 and the second rotating shaft 79 rotate respectively. Since the mounting rods 711 are arranged equidistantly on the second rotating shaft 79, the sludge can be removed better. Since the length of the mounting rod 711 is greater than the radius of the spiral blade 710, the shovel teeth 712 can better contact the sludge. The semi-cylindrical barrel can be prevented from being damaged by the reinforcing rod 27. And the first motor 23, the second motor 73, and the third motor 78 are all connected to an external power source through wires.

[0027] Then, the staff first controls the first motor 23 to start. The output shaft of the first motor 23 can drive the wire winding drum 24 to rotate. The wire winding drum 24 drives the wire rope 25 fixedly connected to its surface to wind or extend. The wire rope 25 can adjust the conveying pipeline 71 to an appropriate height position. Under the own weight of the conveying pipeline 71, the conveying pipeline 71 can be firmly attached to the sludge. Through the action of the two inclined rods 26 and the reinforcing rod 27, the guide roller 28 and the conveying pipeline 71 hung by the wire rope 25 can be supported. And under the action of the guide roller 28, the service life of the wire rope 25 is increased and the wear of the wire rope 25 is reduced. Then, the staff controls the second motor 73 to start, so that the first rotating shaft 74 drives the auger blade one 75 and the auger blade two 76 to rotate simultaneously. Then, the staff controls the third motor 78 to start. The output shaft of the third motor 78 drives the second rotating shaft 79, so that the spiral blade 710 and the mounting rod 711 rotate. The shovel teeth 712 shovel the sludge through the mounting rod 711. The sludge is conveyed through the auger blade one 75, the auger blade two 76, and the spiral blade 710, thus completing the cleaning of the sludge, facilitating the conveyance of the sludge into the collection bin 3, and further facilitating the removal of the sludge with solidified surface. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
