In this embodiment: firstly, the bucket 25 is set to be in an inner straight line and outer arc mode, when the bucket 25 rotates in an arc mode, the bucket 25 can provide certain inner support for the bucket 25 when the inner sludge is centripetal, the bucket 25 is prevented from being spilled out when in arc motion, secondly, when the device moves and the bucket 25 is driven to rotate for dredging, the crank-slider mechanism 41 is driven to start at the same time, the sliding column 40 is driven to reciprocate, when the bucket 25 moves from the top arc mode to the opening-down straight line mode, the sliding column 40 stretches out at the moment, the receiving hopper 35 is driven to be close to the position right below the bucket 25, and meanwhile, the opening of the receiving hopper 35 is enabled to rotate upwards by one hundred eighty degrees through the limit column 39 and the limit of the spiral groove 38, so that the gravity-falling sludge is collected in the bucket 25, then the receiving hopper 35 is rapidly contracted, the collecting process is completed by the limit rotation of the spiral groove 38 and the limit column 39, and the opening is downwards, and the sludge is poured into the collecting box 34, so that the collecting reliability is guaranteed.

Example 6:

in order to solve the thoroughly problem of twice transportation of silt and sediment, as shown in fig. 9, the following improvements are made on the basis of embodiment 5: the inner wall of the connecting frame 36 is rotatably connected with a supporting block 45 through a rotating rod, the outer walls of two sides, close to the receiving hopper 35, of the supporting block 45 and far away from the receiving hopper 35 are respectively welded with a first swing rod 44 and a second swing rod 46, the outer walls of the first swing rod 44 and the second swing rod 46 are respectively fixed with an elastic impact ball 43 through bolts, the length of the first swing rod 44 is smaller than that of the second swing rod 46, and the outer walls of two sides, located on the supporting block 45, of the rotating rod are respectively matched with a torsion spring 42.

In embodiment 5, the sludge and the silt enter the receiving hopper 35 from the dredging hopper 25 and are discharged into the second collecting box 34 from the receiving hopper 35 by gravity, and the sludge and the silt have certain viscosity and are difficult to be completely discharged by gravity alone, so that dredging efficiency is poor.

In this embodiment, when the receiving hopper 35 approaches the dredging bucket 25, the two elastic impact balls 43 receive the same acceleration force, because the swing rod 44 is shorter, the moment generated by the swing rod is smaller than that of the swing rod 46, so that the swing rod 44 and the swing rod 46 rotate clockwise with the view of fig. 9, that is, the elastic impact balls 43 rotate towards the direction close to the receiving hopper 35, when the receiving hopper 35 is at the farthest distance and stops, the elastic impact balls 43 at the swing rod 46 receive inertia and torsion of the torsion spring 42 and impact the dredging bucket 25, and due to the elastic characteristic of the elastic impact balls, multistage impact can be generated on the dredging bucket 25, so that sludge and sediment in the dredging bucket 25 are discharged thoroughly.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
