Efficient dredging device for water conservancy project

Abstract

The invention discloses an efficient dredging device for a water conservancy project. The device comprises a dredging cylinder, pushing pressing spiral blades, waling wheels, a dredging rolling brush,a dredging scrapping plate, a press filtering head and a dredging lifting cylinder, a driving shaft is installed in the dredging cylinder, a pushing pressing roller is arranged on the driving shaft,the pushing pressing spiral blades are arranged on the surface of the pushing pressing roller, the dredging scrapping plate is connected on the dredging cylinder at the bottom of the left side of thepushing pressing roller, a dredging rotary shaft is installed on the upper side of the dredging scrapping plate, and the dredging roller brush are arranged on the surface of the dredging rotary shaft;sludge on the dredging scrapping plate is removed by the dredging rolling brush, pushed to the dredging cylinder on the upper side and pushed rightwards by the pushing pressing spiral blades rotatedalong with the driving shaft, the sludge is intercepted by the press filtering net, moisture is filtered by filtering cottons and flows back to a river through press filtering grates, sludge which ispressed and filtered at the right end of the dredging cylinder is pushed and lifted to the dredging lifting cylinder by rotation of lifting spiral blades on a lifting shaft and lifted upwards to a dredging boat, the dredging operation efficiency is improved, the dredging efficiency is high, and the effect is good.

Description

technical field [0001] The invention relates to the field of environment-friendly dredging machinery, more specifically, it relates to a high-efficiency dredging device for water conservancy projects. Background technique [0002] With the continuous improvement of the level of urban construction, the requirements for urban environmental protection are also increasing. As the focus of urban environmental governance, the governance of urban rivers has also undergone tremendous changes. Since most of the urban river courses have completed the shaping of the riverbed section and the hardening construction of the retaining wall and revetment, the treatment of urban rivers has changed from the past large-scale earthwork clearing, river bed shaping and hardening of the retaining wall and revetment to normal protective dredging . This kind of dredging is a long-term dynamic project with continuous circulation, which cannot be done once and for all. This normalized protective dre...

AI Technical Summary

Problems solved by technology

[0003] Dredging is one of the essential water treatment tasks in water conservancy projects. At present, force-suction dredging machines are often used to remove silt in river channels. Due to the different thickness of river bottom silt and the difficulty of directly absorbing river bottom silt, it often leads to The mud pump of the equipment is blocked and cannot work normally, and the mud concentration is low, and the cost-effective ratio is poor
