The present disclosure relates to a field of water conservancy engineering, and in particular to a dredging device with high efficient
Projects constructed to eliminate water damage and develop and utilize water resources, are divided into flood control projects, farmland water conservancy projects, hydropower projects, waterways and port projects, water supply and drainage projects, environmental water conservancy projects, and marine reclamation projects, etc. according to different service objects. A water conservancy project that can simultaneously serve various targets such as flood control, water supply, irrigation, and power generation, is called a comprehensive utilization water conservancy project. The comprehensive utilization water conservancy project needs to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, crossings, ramps, fish passes, and etc., to achieve their targets. Construction of trenches and canals is the most important part of farmland irrigation. Due to strong winds and heavy rains, dirt and stones on a roadside would fall into the trenches and canals. And with long-term sedimentation, such silt including dirt and stones, would block the trenches and canals. Thus, the trenches and canals need to be dredged to keep the water in the trenches and canals flowing normally. However, the conventional dredging methods still have following deficiencies.
Most conventional dredging methods for trenches and canals are manual dredging and dredging by a sludge pump. In views of manual excavation for dredging, although cleaning effect is good, but the long-term sedimentation of the sludge leads to high hardness of the silt and make it difficult to dig, which makes low dredging efficiency of the manual dredging. Further, labor intensity of staff is too high, and use effect is not satisfactory. Use of the sludge pump for dredging only has a good effect on removal of pure muddy water, but the stones and garbage in the sludge would block the sludge pump, which damages the sludge pump, causes great economic loss to the user. Moreover, water in extracted mud water is relatively large, and the sludge is relatively small, and a use effect of the sludge pump is not satisfactory.
The present disclosure provides a dredging device with high efficient to solve problems in the prior art.
The dredging device of the present disclosure includes a second motor, a baffle and crushing wheels. When using the dredging device, the second motor is turned on to drive a first gear to engage with second gears, so that the rotating shafts drive the crushing wheels to crush sludge and larger stones, which facilitates a salvage of salvaging hoppers, solves problems of low efficiency and high labor intensity by conventional manual dredging. The baffle blocks an upper portion of the crushing wheels to avoid sludge splashing on a worker at a side of a trench or a canal during crushing, which improves usability of the dredging device.
The dredging device of the present disclosure includes a first motor, salvaging hoppers and limiting blocks. When using the dredging device, the first motor is turned on to drive the transmission belt to rotate, so that the salvaging hoppers salvage the sludge. An adaptability of the salvaging hoppers is much greater than that of a sludge pump, which solves a problem that the sludge pump is easily blocked by the sludge. The salvaging hoppers are able to salvage garbage and the stones in the sludge to improve a cleaning effect. The use of the salvaging hoppers with the crashing device reduces a labor intensity of the worker avoids blocking caused by the sludge, and improves a dredging efficiency, which is convenient for a user.
The dredging device of the present disclosure includes the salvaging hoppers, a sludge discharging hopper, and an adjusting device. First filter holes on surfaces of the salvaging hoppers discharge the water in the sludge before salvage, and the sludge discharging hopper filter the water again with the second filter holes at a bottom of the sludge discharging hopper to reduce a proportion of water in the sludge. Two groups of movable wheels cooperate with stabilizing cylinders and stabilizing rods to make the dredging device more stable when moving and when placed. The dredging device dredge the sludge while moving, which improves a dredging efficiency, reduces the labor intensity of the workers, so that the adaptability of the dredging device is improved.
The present disclosure will be further described with reference to the drawings and embodiments.
