Abstract:
This invention provides a manufacturing method for an efficient diamond geological drill bit, relating to the field of geological drill bit technology. The drill bit includes a main body with a threaded drill rod in the center, where the inner wall of the threaded drill rod is fixedly connected to the outer wall of a fixed cylinder. The top of the fixed cylinder has fixed semi-rings, symmetrically distributed on the cylinder. The inner upper end of the fixed semi-rings has fixed blocks, which are connected to the bottom end of the drill teeth. The bottom end of the fixed cylinder is connected to the top surface of a second fixed plate, which in turn is connected to the top end of a shock-absorbing telescopic rod. The top end of the shock-absorbing telescopic rod is connected to the top surface of a first fixed plate. This design features a shock-absorbing telescopic rod to dampen vibrations during drilling, ensuring stability.
