Abstract

The invention relates to the field of hob drill bits, in particular to an inverse well rock stratum inserted tooth hob drill bit which comprises a base. A fixing rod is connected on the base and provided with a cutter bit through a bearing, the base comprises a bottom plate, a low-position connecting rod is fixed at one end of the bottom plate, the other end of the low-position connecting rod is hinged to one end of the fixing rod through a ball, a high-position connecting rod is fixed at the other end of the bottom plate, the other end of the high-position connecting rod is connected with a side movement fixed mechanism, a side movement slidable mechanism is connected at the other end of the fixing rod and sleeves the inside of the side movement fixed mechanism, and an angle adjusting mechanism is arranged in the middle of the high-position connecting rod. According to the inverse well rock stratum inserted tooth hob drill bit, an inclined angle is automatically adjusted through the cutter bit, drilling efficiency is effectively improved, and vibration can be reduced, and the inverse well rock stratum inserted tooth hob drill bit solves the problems of low drilling speed and high vibration damage rate of an existing inverse well hob drill bit.

Description

technical field [0001] The invention relates to the field of hob bits, in particular to a hob bit with inserts for raising rock formations. Background technique [0002] The technical principle of the raise drilling rig is that the motor of the drilling rig drives the hydraulic motor, the hydraulic motor drives the faucet, and uses the hydraulic power to transmit the torque to the drilling tool system, which drives the drill pipe and the drill bit to rotate, and the hob on the pilot hole drill bit or the reamer bit Under the action of drilling pressure, pure rolling or slight slip along the bottom rock working face. At the same time, the axial tension and pressure generated by the oil cylinder of the main engine also act on the pilot hole drill bit or the reaming drill bit through the power head and drill rod, so that the hob of the pilot hole drill bit rolls under the action of drilling pressure, resulting in impact load, making the hob The teeth impact, squeeze and shear ...
