As shown in fig. 4, the dredging spiral 201 is provided as a spiral-wound solenoid.
The mud cleaning spiral 201 is arranged into a spiral surrounding solenoid, and the hollow structure of the mud cleaning spiral provides a path for inputting the mud, so that the mud cleaning spiral 201 occupies small space and avoids influencing the input speed of the mud. When the mud cleaning spiral rotates around the shaft, the spiral structure plays a role in scraping and rubbing the surrounding sludge, so that the sludge adhered to the pipe wall is cleaned, the sludge is prevented from being adhered to the feeding pipeline in the input process, and a better mud cleaning effect is achieved.
In an example according to the present invention, the outermost side of the mud cleaning screw 201 is attached to the pipe wall of the feeding pipe 101, as shown in fig. 3, the diameter of the solenoid of the mud cleaning screw 201 wound in a spiral shape is equal to the diameter of the feeding pipe 101, so that the outermost side of the solenoid is attached to the pipe wall of the feeding pipe, which can clean the mud on the pipe wall in real time during the process of feeding the mud into the feeding pipe 101, and further improves the mud cleaning effect.

In one example according to the invention, as shown in fig. 4, the spiral 203 is provided as a tripod with the three leg ends lying on concentric circles of the feeding section. The three leg ends of the tripod are arranged to lie on concentric circles of the feed pipe to further avoid the feed screw from deviating from the axis of rotation. Simultaneously, the three legs of the tripod agitate the sludge entering the feed pipe 101, thereby distributing the sludge entering the feed pipe 101.
In one example according to the invention, as shown in fig. 4, the diameter of the concentric circle in which the three legs of the screw clamp 203 arranged as a tripod lie is smaller than or equal to the diameter of the feed pipe.
In one example according to the present invention, a control device that controls the driving device to perform a driving operation is further included. Under the control of the control device, the preset cleaning frequency and the cleaning time can be set, so that the sludge cleaning device can periodically perform sludge cleaning operation.
