TECHNICAL FIELD

[0002] In the related art, because the water flow in the river is gentle, silt will be generated on the riverbed after a period of time, and if not cleaned in time, the silt on the riverbed will be accumulated too much, thereby raising the riverbed, and further affecting the ability of drought resistance, drainage and irrigation, and also causing phenomena such as river blockage and poor water quality.

[0003] The prior art (publication number: CN113482083B) discloses a river dredging device for water conservancy projects.

The silt scraped up is received by the silt receiving cloth 18, and at the same time, the silt receiving cloth 18 and the scraper 15 are inclined, so that the silt can enter the sewage collecting tank 22 for collection. At this time, the sludge pump 24 draws the silt and river water gathered in the sewage collecting tank 22 through the mud pipe 25, and discharges them into the sludge pool beside the river 36.

[0017] Compared with the prior art, the water conservancy river channel dredging device has the beneficial effects that:

[0018] 1. The first lifting mechanism is moved by the first pushing mechanism, and the first lifting mechanism drives the silt box up and down to remove the silt at the bottom of the river channel; at the same time, the silt is compressed by the compression pushing mechanism to squeeze out the water in the silt and compress the silt, thereby reducing the space occupied by the silt to facilitate subsequent storage of the silt.

Moreover, the silt is removed by the silt box, avoiding the use of sludge pump to suck the silt, thereby avoiding the situation that the sandstone in the river blocks the sludge pump, further improving the quality of the product.

[0019] 2. The first guide seat is fixed at the bottom of the mounting frame, the first linear bearing is sleeved on the outside of the first guide rod, and the first linear bearing is embedded in the first guide seat, so that the first guide seat guides the first guide rod through the first linear bearing, thereby avoiding the first lifting mechanism from deviating during movement, and improving the stability of the first lifting mechanism.

[0020] 3. The first motor is fixed on the support frame, and the first motor is connected with the first lead screw, so that the first motor drives the first lead screw to rotate, thereby providing power for rotating the first lead screw; the first lead screw passes through the first threaded hole of the lifting block, and the lifting block is rotatably connected with the silt box, so that the lifting block is threadedly connected with the first lead screw, thereby realizing the first lead screw driving the lifting block and the silt box to move up and down. The first light rod is embedded in the accommodating groove, the two ends of the first light rod are connected with the support frame, and the first light rod passes through the lifting block, so that the support frame supports the first light rod, thereby realizing the lifting block moving up and down along the first light rod, and improving the stability of the lifting block moving and the silt box moving.

[0021] 4. The second hydraulic cylinder is fixed at the top of the compression cavity, and the pressing plate is connected with the second output shaft of the second hydraulic cylinder, so that the second hydraulic cylinder drives the pressing plate to move downward, thereby realizing the pressing plate compressing the silt to squeeze out the water in the silt and reducing the space occupied by the silt, thereby facilitating subsequent storage of the silt. The third hydraulic cylinder is fixed on the side wall of the compression cavity, the pushing plate is connected with the third output shaft of the third hydraulic cylinder, and the pushing plate is opposite to the discharge port, so that the third hydraulic cylinder drives the pushing plate to move, thereby realizing the pushing plate pushing the silt out of the discharge port.

[0022] 5. The push plate drives the brush to move on the bottom of the compression cavity, thereby cleaning the bottom of the compression cavity and avoiding the silt from blocking the third drainage hole, so as to improve the use experience of the product.

[0023] 6. When the rotating shaft drives the winding drum to rotate, the winding drum winds or unwinds the steel wire rope, thereby driving the guide box to move up and down.

[0024] 7. When the push plate moves, the push plate drives the second deflection plate to move through the two connecting rods, thereby improving the stability of the push plate movement.

[0025] 8. The third lead screw is screwed with the moving plate, so that when the third lead screw rotates, the third lead screw drives the moving plate to move, thereby enabling the conveying mechanism to be located below the guide box.

[0026] 9. When the transmission roller rotates, the transmission roller drives the conveyor belt to move, thereby enabling the conveyor belt to drive the silt to move.

[0027] 10. When the silt box moves to the first deflection plate, the plurality of first guide wheels are in contact with the inclined surface of the first deflection plate, thereby enabling the plurality of first guide wheels to roll along the inclined surface of the first deflection plate, so as to avoid rigid contact between the silt box and the first deflection plate, thereby avoiding damage to the silt box and improving the quality of the product. The second guide wheel is enabled to rotate between the two mounting portions, so as to enable the second guide wheel to roll on the inclined surface of the second deflection plate, thereby avoiding rigid contact between the guide box and the second deflection plate, thereby avoiding damage to the guide box and improving the quality of the product.

[0028] 11. When in use, all the drive devices (i.e. the first hydraulic cylinder, the first motor, the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, the second motor, and the third motor) in the product are located on the water surface, thereby avoiding damage to the drive devices due to water ingress.
