[0043] Working principle:
[0044] When in use, the device is operated and controlled by the remote control device and the remote control system. The device is transported into the river channel and operated and controlled by receiving the remote control signal through the signal receiving antenna 11. The first hydraulic telescopic rod 7 is controlled to work to drive the connecting bracket 2 to swing, thereby adjusting the ground clearance of the left side of the connecting bracket 2. The second hydraulic telescopic rod 8 is controlled to work to drive the silt bucket 3 to swing, thereby adjusting the ground clearance of the opening of the silt bucket 3. After the opening of the silt bucket 3 is adjusted to a position suitable for dredging, the bottom of the opening of the silt bucket 3 is made to fit the bottom of the river channel. At this time, the crawler-type moving wheels 9 are controlled to operate to drive the frame 1 to move, thereby pushing the silt bucket 3 to move. The silt at the bottom of the river channel is shoveled up through the movement of the silt bucket 3 and the silt enters the inner cavity of the silt bucket 3 through the movement of the silt bucket 3. The stones and large objects in the silt are blocked by the filtering baffle 4, so that only the mixture of silt and water enters the deep inner cavity of the silt bucket 3. The driving motor 503 is controlled to start The driving shaft 504 is driven to rotate by the driving shaft 504, and the spiral conveying plate 505 is driven to rotate by the rotation of the driving shaft 504. The silt in the deep inner cavity of the silt bucket 3 is rolled into the inner cavity of the spiral conveying box 501 and thrust is applied by the rotation of the spiral conveying plate 505. The silt is pushed to the inner cavity of the conveying pipe 6 and conveyed by the thrust of the driving shaft 504. The silt and water are conveyed to the outside of the river channel through the conveying pipe 6 for filtration, and the filtered water flows back into the river channel. When there are many stones blocked by the filter baffle 4, the left side of the silt bucket 3 is driven to rise by controlling the second hydraulic telescopic rod 8 to work, so that the stones are lifted and retained in the inner cavity of the silt bucket 3. The left side of the connecting bracket 2 is driven to rise by controlling the first hydraulic telescopic rod 7 to work, so that the opening of the silt bucket 3 is completely upward, so that the stones will not fall, and then the crawler moving wheel 9 is controlled to operate to drive the frame 1 to move, so that the device moves to the outside of the river channel to transfer the stones out of the river channel, and then the device is controlled to return to the river channel to continue working.
