[0008] A desilting mechanism for a water conservancy project comprises a protective cover, a power motor is arranged on the protective cover, a silt extraction assembly is arranged inside the protective cover, a plurality of stirring heads are arranged outside the silt extraction assembly in the protective cover, and a transmission assembly is arranged between the power motor and the silt extraction assembly;

[0009] The sludge extraction assembly includes a sludge pump head disposed in the protective cover, through which the sludge-containing water in the protective cover is extracted;

[0010] The transmission assembly includes a main shaft for connecting the power motor and the sludge pump head, and a plurality of the stirring heads are provided with transmission shafts. A transmission unit is provided between the transmission shaft and the main shaft, and the stirring head and the sludge pump head can work simultaneously through the transmission unit.

[0011] Preferably, the protective cover comprises a cover body with a partition plate arranged on the inner side, and a plurality of connecting frames are arranged on the top of the cover body.

[0014] Preferably, the upper end of the transmission shaft passes through the partition plate and is rotatably connected to the partition plate, and the transmission unit includes transmission wheels arranged on the main shaft and the transmission shaft, and the corresponding two transmission wheels are connected by a transmission belt.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] Through the coordinated use of the protective cover, power motor, silt extraction assembly, stirring head and transmission assembly, the connecting plate is driven downward by the hydraulic cylinder body to allow the stirring head to be inserted into the silt, the power motor is used to drive the main shaft to rotate, and the transmission wheel and belt transmission are used to make the sludge pump head and the stirring head work at the same time.
