Dredging head applied to jet-suction type dredging of river channel

The utility model discloses a desilting head applied to jet-suction type desilting of a river channel. The desilting head comprises a mud suction pipeline, a high-pressure water outlet pipeline, a flow baffle and a soft skirt edge. The sludge suction pipeline is axially parallel to the high-pressure water outlet pipeline; the flow baffles are arranged on the sludge suction pipeline and the high-pressure water outlet pipeline; the soft skirt edge is arranged on the edge of the outer ring of the flow baffle; and a moving device is arranged on the flow baffle. The movable flow baffle is arranged on the desilting head, and by means of the influence of the flow baffle on jet flow, the problem that when an existing sludge pump conducts sludge pumping operation, due to the fact that a large amount of river water above a sludge layer is pumped, the sludge pumping work efficiency is low is solved. 本实用新型公开了一种应用于河道射吸式清淤的清淤头，包括吸泥管道、高压出水管道、挡流板、软裙边；所述吸泥管道和所述高压出水管道轴向平行；所述挡流板设于所述吸泥管道和所述高压出水管道上；所述软裙边设于所述挡流板的外圈边缘；所述挡流板上设有移动装置。
