Description

Technical Field

[0001] This utility model relates to the technical field of dredging devices for water conservancy projects, and in particular to a high-efficiency dredging device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their goals.

[0003] In cities, drainage channels are major water conservancy projects. When these channels become clogged with silt, they need to be dredged. Currently, dredging of such channels is mainly done manually, using tools such as shovels to remove the silt and bag it. In the existing technology, a utility model patent with publication number CN215483231U discloses a high-efficiency dredging device for water conservancy projects. This device's overall structure can be directly placed into the drainage ditch. A reduction motor transmits torque to a second rotating shaft through its output shaft, thereby driving a second roller to rotate. The second roller, conveyor belt, and first roller are linked. When the second roller rotates, the first... The rollers also rotate, while the conveyor belt moves at a constant speed. Bags are hung on the first and second hooks. Using tools such as shovels, silt is shoveled onto the conveyor belt, which carries the silt upwards at an angle. When it reaches the end, the silt falls into the bag, automatically completing the silt bagging process and improving the efficiency of dredging. In addition, the overall structure is small in size, so it will not adversely affect nearby traffic when dredging urban drainage channels. It is equipped with first and second locking casters to facilitate the movement of the overall structure, making it easy for people to use. The overall structure is simple, easy to operate, and the effect is better than traditional methods.

[0004] The sludge removal device in the aforementioned patent has certain drawbacks in use. When hanging the bags containing sludge, it cannot support the bottom of the bags according to their length, which can easily cause the bottom of the bags to suspend in the air. This can cause the bags to shake when filling with sludge, or even cause them to fall off the hooks, affecting the filling of the sludge bags. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-efficiency dredging device for water conservancy projects that can support the bottom of the bag according to its length, prevent the bottom of the bag from being suspended, avoid the bag from shaking when filling with silt, effectively prevent the bag from falling off the hook, and ensure the normal filling of silt.

Two sets of horizontal plates are fixedly connected to the right end of each of the two sets of support legs. Two sets of threaded rods are symmetrically and rotatably mounted on the two sets of horizontal plates. The support plate is screwed onto the two sets of threaded rods through the threaded holes. A transmission rod is rotatably mounted below each of the two sets of support legs. An internal hexagonal nut is fixedly provided at the front end of the transmission rod. Worm sections are provided on both sides of the outer wall of the transmission rod. Worm wheels are fixedly fitted at the bottom of each of the two sets of threaded rods, and the two sets of worm sections mesh with the two sets of worm wheels respectively.

[0008] Preferably, two sets of T-shaped sliders are symmetrically fixedly connected to the left end of the tray. The two sets of T-shaped sliders are integrally formed with the tray. The right ends of the two sets of support legs are provided with T-shaped grooves that match the T-shaped sliders.
