Abstract:
This invention provides a diamond geological drill bit capable of cooling and chip removal, related to the field of drill bits. The drill bit includes a connector with the drill bit body set on its upper end, inside which is a chamber housing an impact hammer. The impact hammer extends from the upper end of the drill bit body and includes an impact main body with a third water channel inside. An outlet is on the upper side wall of the impact main body, and an inlet at the bottom, with the inlet and outlet interconnected by the third water channel. Inside the inlet is a baffle, with a seal pad fixedly connected near the third water channel at the baffle's upper surface, and a guide hole in the middle of the baffle. This structure utilizes the water hammer effect to increase drilling speed while providing cooling and chip removal benefits.
