[0029] While the square rod 613 drives the block 621 to swing back and forth, the block 621 drives the vertical rod 71 to swing back and forth, the vertical rod 71 drives the L-shaped rod 72 to swing back and forth, the L-shaped rod 72 drives the horizontal plate 73 to swing back and forth, the horizontal plate 73 drives the mesh plate 74 to swing back and forth, and the mesh plate 74 drives the U-shaped plate 75 to swing back and forth, so that during the reciprocating swing of the mesh plate 74, the mesh plate 74 blocks the plastic bags in the river channel from entering the bucket 6, and during the reciprocating swing of the U-shaped plate 75, the plastic bags on the mesh plate 74 will briefly stay on the U-shaped plate 75, and when the equipment is clearing the silt at the bottom of the river channel, the plastic bags at the bottom of the river channel will not enter the bucket 6, preventing the plastic bags from being blocked under the straight pipe 5 when the equipment is in use, thereby avoiding the problem of the equipment being blocked by the plastic bags due to the plastic bags being blocked under the straight pipe 5 when the dredging device is in use.

[0030] While the horizontal plate 73 drives the mesh plate 74 to swing back and forth, the mesh plate 74 drives the connecting block 76 to move back and forth, the connecting block 76 drives the arc-shaped elastic bar 2 77 to move back and forth, the arc plate 78 supports the arc-shaped elastic bar 2 77, and the arc-shaped elastic bar 2 77 begins to deform back and forth, so that during the mesh plate 74 reciprocating swing, the mesh plate 74 generates an amplitude under the elastic force of the arc-shaped elastic bar 2 77, so that the mesh plate 74 shakes off the plastic bag to prevent the plastic bag from adhering to the mesh plate 74 when the equipment is in use, thereby avoiding the problem of poor filtering effect of the mesh plate 74 caused by the plastic bag adhering to the mesh plate 74 when the dredging device is in use.

[0031] While the grid plate 74 drives the U-shaped plate 75 to swing back and forth, the U-shaped plate 75 drives the short column 81 to swing back and forth, the short column 81 drives the bottom strip plate 82 to swing back and forth, the bottom strip plate 82 drives the hook rod 83 to swing back and forth, and the hook rod 83 drives the L-shaped shovel plate 84 to swing back and forth, so that in the process of the L-shaped shovel plate 84 swinging back and forth, the L-shaped shovel plate 84 removes the aquatic plants at the bottom of the river channel, and the short column 81 blocks the aquatic plants from entering the bucket 6, so that the aquatic plants will not be entangled on the bucket 6, preventing the aquatic plants from being entangled on the bucket 6 when the equipment is in use, thereby avoiding the problem of aquatic plants being entangled on the bucket 6 and causing the bucket 6 to be pulled and damaged when the dredging device is in use.

[0032] While the short column 81 drives the bottom strip 82 to swing back and forth, the bottom strip 82 drives the clamping plate 85 to swing back and forth, the clamping plate 85 drives the circular frame 86 to swing back and forth, and the circular frame 86 drives the mesh 87 to swing back and forth, so that during the reciprocating swing of the mesh 87, the mesh 87 blocks the fine aquatic plants from entering the bucket 6, so that the straight pipe 5 will not suck in the fine aquatic plants when the equipment is in use, thereby avoiding the problem of the straight pipe 5 sucking in the fine aquatic plants when the dredging device is in use, causing the inside of the mud pump 2 to be entangled with the fine aquatic plants.
