[0002] At present, in water conservancy projects, the river channel is of great significance as the main path of water circulation. When the sediment content in the water flow is large, it will often deposit and form silt at the bottom of the river, which will reduce the drainage of the river channel and cause the problem of poor drainage. , in some areas with heavy rainfall, it is one of the main factors for floods. In order to increase the drainage of the river, it is necessary to carry out dredging operations on the river regularly. Usually, the dredging of the river is to use mechanical equipment to blow and stir the silt deposited on the bottom of the river into turbid water. It can be installed and flowed with the river water to play the role of dredging. Usually, the mixing head is used to stir the riverbed silt. The driving motor drives the transmission rod to rotate, and the transmission rod transmits the rotation to the stirring head to stir the sludge. The transmission rod It is usually a long straight steel pipe. When stirring the sludge, the plane where the stirring head rotates is perpendicular to the transmission rod. For the cleaning of potholes on the river bank, the whole rotating rod needs to be deflected by a certain angle, and the stirring head is sent to the It is more troublesome to adjust the overall deflection, and the length of the deflected transmission rod is longer than the length of the vertical insertion. When the mixing depth is deep, the transmission rod must have sufficient length, otherwise it will not be able to complete the mixing. It is conducive to the implementation of water conservancy dredging work. The adjustment of the angle of the existing water conservancy dredging mixing head is completed through gear meshing. The adjustment angle is limited and when working in underwater silt, it is prone to jamming and the use effect is not good.
