Anti-blocking reamer device for dredging engineering

The anti-blocking reamer device for the dredging engineering comprises an outer shell, and an outer reamer mechanism, an inner reamer mechanism and a high-pressure spraying mechanism are installed in the outer shell. The outer reamer mechanism comprises a transmission main shaft, a main shaft gear and an outer reamer; the inner reamer mechanism comprises an outer sleeve, an outer sleeve gear, an inner reamer and a fixing frame; the anti-blocking reamer device is compact and reasonable in structure, convenient to use and capable of being suitable for various geological conditions, in the rock-soil cutting process of the outer reamer mechanism and the inner reamer mechanism, large rock-soil blocks can be crushed into fine rock-soil particles through the reamer and the high-pressure spraying and flushing mechanism in real time, the fine rock-soil particles are fully mixed with water to form slurry, and therefore the anti-blocking effect is achieved. And finally, the slurry is pumped out through a suction pipe in
