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.
