[0042] Working principle: The unmanned boat 1 is remotely controlled to move to the area to be cleaned in the river. After reaching the area to be cleaned, the piston rod of the hydraulic cylinder 29 is extended, driving the rotating arm 27 to rotate clockwise, opening the semi-enclosed silt cleaning shovel 22, so that the semi-enclosed silt cleaning shovel 22 is inserted into the silt until the pressure sensor at the bottom of the semi-enclosed silt cleaning shovel 22 collects the pressure value reaching the set value, closes the hydraulic cylinder 29, and turns on the sewage suction and crushing motor 21, the transmission drive motor 48 and the stirring and lifting drive motor 42 at the same time. The unmanned boat 1 continues to move forward. During the process of moving, the silt at the bottom of the river is shoveled off with the help of the semi-enclosed silt cleaning shovel 22, and the sewage is sucked into the semi-enclosed silt cleaning shovel under the action of the sewage suction blade 24. Inside the enclosed dredging shovel 22, the lumped silt is broken up by the action of the spiral crushing blades 25, and then input into the mixing barrel 41 through the hose 3, and then lifted up by the stirring and lifting spiral shaft until it reaches the entrance of the connecting channel 410, and then discharged from the connecting channel 410, falling into the compression channel, where it is compressed, and excess water is discharged from the drainage hole 10. The compressed silt is adhered to the annular filter cloth belt 46, and is conveyed to the leveling plate 47 as the annular filter cloth belt 46 is leveled to the set height (to avoid some silt being too thick and causing incomplete drying), and then dried by the blower head 45, and then shoveled into the material shovel 43 for storage.
[0043] Therefore, the present invention adopts the river dredging device for ecological restoration with the above structure, which can shovel and crush the silt at the bottom of the river as the unmanned boat moves, and then compress and collect it. It has the advantages of short repair cycle, good cleaning effect, high sludge storage rate, and no damage to the river ecological environment.
