[0025] A dredging device for river channels, such as Figures 1-4As shown, the system includes a support frame 1, a mud pump 2, and a bucket 3, all mounted on the vessel. The mud pump 2 is fixedly connected to the support frame 1, and the bucket 3 is rotatably connected to the support frame 1 via connectors. The support frame 1 is welded from high-strength alloy steel and has a frame structure with multiple mounting holes at the bottom. It is securely mounted to the deck of the dredger using high-strength bolts. Its unique triangular support design greatly enhances overall stability, ensuring stable operation even in fast-flowing river channels. The mud pump 2 is a high-power centrifugal mud pump, fixed to the mounting platform at the top of the support frame 1 using shock-absorbing bolts.
[0026] Furthermore, the bucket 3 is made of high-strength wear-resistant alloy steel in a cylindrical structure. One end of the bucket 3 has an inlet 4, and the other end has an outlet 5. The outlet 5 is connected to the mud pump 2 via a connecting pipe 6. Dredging operations typically involve blocking the river channel and discharging some water to lower the water level, facilitating dredging. During the dredging process, as the dredging vessel moves forward, the bucket 3, near the inlet 4, has a shovel assembly for scooping up silt. The silt is scooped up by the shovel assembly and enters the bucket 3 through the inlet 4. Pump 2 generates suction to remove the silt. A rust-proof blade 7 is fixedly connected inside the bucket 3. The rust-proof blade 7 is fixed on the side of the bucket 3 near the discharge port 5. When the bucket 3 rotates, it can also drive the rust-proof blade 7 to rotate, thereby breaking up the silt before it enters the discharge port 5, preventing it from clogging the connecting pipe 6, and improving the silt discharge efficiency. Several guide baffles 8 are fixedly connected at the inlet 4. The guide baffles 8 are inclined inwards towards the bucket 3. There are three guide baffles 8, which are welded to the inlet 4 to guide the riverbed silt from the inlet 4 into the bucket 3.
[0027] In one embodiment, the shovel assembly includes a shovel plate 9 and an arc-shaped adjusting plate 10. A limiting ring 11 is fixedly connected to the bucket 3, and the arc-shaped adjusting plate 10 is slidably connected to the limiting ring 11. The shovel plate 9 and the arc-shaped adjusting plate 10 are fixedly connected. During shovel operations, the bottom surface of the shovel plate 9 can be adjusted to be parallel to the bottom surface of the riverbed. The front side of the shovel plate 9 is relatively sharp, which can shovel up the silt during the forward movement of the bucket 3. During the rotation of the bucket 3, the arc-shaped adjusting plate 10 and the bucket 3 can be fixed together with bolts in advance, so that the shovel plate 9 can make a circular motion in the silt to separate the silt and make it easier for the silt to be sucked into the bucket 3.
[0028] In one embodiment, the connector includes a waterproof motor 12, a positioning frame 13, a connecting rope 14, and a spool 15. The spool 15 is mounted on the bracket 1. The positioning frame 13 is fitted onto the outside of the bucket 3. A bearing 16 is provided between the positioning frame 13 and the bucket 3. The waterproof motor 12 is fixedly connected to the positioning frame 13, and the output end of the waterproof motor 12 is fixedly connected to the center of the bucket 3. One end of the connecting rope 14 is wound around the spool 15, and the other end of the connecting rope 14 is fixedly connected to the top of the positioning frame 13. The length of the connecting rope 14 is adjusted by winding and unwinding the spool 15, thereby adjusting the height of the bucket 3 to reach the working height for convenient dredging work. Several connecting ropes 14 are provided, and the connection points of the connecting ropes 14 and the positioning frame 13 form a plane. The connecting ropes 14 are made of corrosion-resistant material. There are three connecting ropes 14 distributed on the top surface of the positioning frame 13. The connection points of the three connecting ropes 14 and the positioning frame 13 form a triangular plane to ensure the stability of lifting the bucket 3.
[0029] In one embodiment, the size of the inlet 4 is the same as the inner diameter of the bucket 3, the outlet 5 is eccentrically located on one side of the bucket 3 and the outlet 5 is smaller than the inner diameter of the bucket 3, an extension plate 17 is fixedly connected to the side of the bucket 3 near the outlet 5, a connecting plate 18 is rotatably connected to the extension plate 17, an outlet 19 is opened on the connecting plate 18, and the end of the connecting pipe 6 away from the mud pump 2 is fixedly connected to the outlet 19. When the waterproof motor 12 drives the bucket 3 to rotate, the connecting plate 18 and the bucket 3 rotate relative to each other. Since the connecting plate 18 and the connecting pipe 6 are fixedly connected to each other, the bucket 3 will not drive the connecting pipe 6 to rotate during the rotation, so that the connecting pipe 6 is not easy to rotate and get tangled.
[0030] The usage process of this utility model is as follows:
[0031] The dredger, powered by its own engine, travels to the designated dredging area. The operator first lowers the connecting rope 14 via the control panel, aligning the inlet 4 precisely with the silt accumulation area on the riverbed. Then, the waterproof motor 12 is started, causing the bucket 3 to rotate. Simultaneously, the mud pump 2 is activated, generating negative pressure that allows the silt to flow through the guide baffle 8 into the bucket 3. As the bucket 3 rotates, the rust-proof blades 7 on the inner wall break up the silt. The broken silt then flows through the outlet 5 into the connecting pipe 6, and is finally extracted by the mud pump 2 and transported through the delivery pipeline to the designated silt storage area. Throughout the operation, the operator can adjust the length of the connecting rope 14 by controlling the retraction and extension of the spool 15, based on the actual dredging depth and changes in the riverbed topography. This allows for adjustments to the height and angle of the bucket 3, ensuring a smooth and unobstructed dredging process, thus achieving efficient and stable river dredging operations.
[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
