Abstract
The invention provides a rotor drill bit of an all-hydraulic reverse circulation drilling machine. The rotor drill bit comprises three rotor shaft seat assemblies, a transfer case assembly, a power input assembly, a rotor assembly, and a conveying pipeline welding member. When a motor of the rotor drill bit works, the motor drives three rotors and rotor vertical drills to rotate at the same time, what is equal to that a plurality of drills drill at the same time, and the work efficiency of a large-aperture drill can be raised. Because the rotor drill bit is individually driven by the motor, forces applied to a drilling rod and a power head are distinctly reduced, and problems that the power of a drilling machine is insufficient and a drilling rod is easy to damage can be solved. The rotor drill bit can be easily use for drilling a large deep hole, the technical issue which is badly needed to be solved can be solved. The rotor drill bit of the all-hydraulic reverse circulation drilling machine can be used for drilling clay and sandy soil geological stratifications, also can be used for drilling wide aperture holes in lithosphere, and the drilling speed is quick and the efficiency is high.
