Novel environment-friendly dredging head

Abstract

The invention provides a novel environment-friendly dredging head. The novel environment-friendly dredging head comprises a shell and a supporting rod, wherein the supporting rod is fixedly connectedto the upper surface of the shell, a screw rod is transversely arranged in the shell, blades are arranged on the screw rod, the blades are spirally distributed along the axis direction of the screw rod, the left end of the shell is provided with an open end, a bearing is arranged at the right end of the shell in a sleeve mode, a driving motor is arranged at the right end of the screw rod, a waterinlet pump and a silt suction pump are arranged on the two sides of the supporting rod correspondingly, the supporting rod is internally provided with a signal cable, and one end of the signal cable is electrically connected with the water inlet pump, the silt suction pump and the driving motor. According to the novel environment-friendly dredging head, the screw rod carries out reversely rotatingmovement, so that the sludge is promoted to enter the shell along the screw rod, it is ensured that the sludge can enter the shell under the condition that the sludge does not diffuse in the water, meanwhile, the good cutting performance and crushing capability of the blades are matched, so that the dredging work is well completed, the working efficiency is effectively improved, and meanwhile, the energy is saved, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of dredging equipment, in particular to a novel environment-friendly dredging head. Background technique [0002] Nowadays, the problem of river silt is becoming more and more prominent, especially in rural areas that lack sewage treatment capacity. The criss-crossing small rivers are extensive and large. Excessive thickness of river silt makes the effective depth of the river shallow, and the water capacity and drainage and irrigation capacity decrease. Increased pollution and deterioration of the water ecological environment have weakened the comprehensive agricultural production capacity and affected the production and life of the people. Dredging is the most effective engineering measure for the protection of rural water resources, water ecology and water environment. [0003] At present, the basic methods of existing dredging small rivers are roughly divided into the following two types: (1) use a water...

Problems solved by technology

[0003] At present, the basic methods of existing dredging small rivers are roughly divided into the following two types: (1) use a water pump to drain the water in the river, then use a high-pressure water gun to wash the mud into mud, and use a mud pump to pump the mud to the bank for sedimentation , this method is more thorough in dredging, but it is easy to cause the diffusion of silt, which will lead to the destruction of the surrounding water ecology, the deterioration of water quality, and the death of animals and plants; The mud can be pumped to the shore for sedimentation, which can carry water to work, but it is not easy to control, and the price of the equipment is high. Now a new technical solution is needed to solve the above problems
