Working principle:

firstly, the dredging arm 11 rotates with the dredging head 12, then the dredging head 12 agitates the sludge, the sludge is stirred into muddy water, then the muddy water is pumped by a slurry pump and is discharged through the dredging elbow pipe 13, the guide straight pipe 23, the guide taper pipe 22, the filtering concave cavity 31 on the working position, the C-shaped hole 32, the inlet channel 703, the conversion disc cavity 702, the discharge channel 704, the butt joint pipe 705 and the dredging hose 14, in the process, the grating filter disc 35 on the working position intercepts sundries such as stones in the muddy water, as the grating filter disc 35 intercepts sundries, the blocked and blocked meshes on the grating filter disc 35 are increased, so that the thrust force born by the grating filter disc 35 is increased, then the grating filter disc 35 moves upwards with the piston cylinder 33 under the action of the thrust force, then the piston cylinder 33 presses the strain spring 36, and then the strain spring 36 compresses elastically, the elastic potential energy increases, at the same time, during the flow of the muddy water inside the conversion plate cavity
