then the control cylinder 336 is started, the control cylinder 336 is extended, so that the opening of the stirring tank 331 is opened by the sealing plate 335, and the mud-water mixture enters the second screw conveyor 340 and is conveyed by the second screw conveyor 340 to enter the farmland for reuse;

the staff pushes the bottom plate 100 to move along the river channel direction until the cleaning of the sludge and the aquatic plants in the whole river channel is completed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
