Abstract
The utility model provides an efficient drill bit for a mine drilling machine, which belongs to the technical field of drill bits and comprises a drill rod and a drill bit body arranged on the drill rod, a flange ring is mounted on the outer wall of one end of the drill rod, and a fixing seat is arranged at one end of the drill rod. According to the utility model, the crushing teeth arranged on the drill bit body are matched with the buffer springs, so that the positions of the crushing teeth can be effectively and automatically adjusted according to the hardness of external rocks and the drilling pressure, thereby reducing greater abrasion of the crushing teeth caused by hard rocks or abnormal loads, prolonging the service life of the drill bit, and improving the drilling efficiency at the same time; the spiral blade arranged outside the drill rod close to one end of the mounting seat continuously lifts the waste drilling fluid between the drill rod and the well wall in the process of synchronously rotating along with the drill rod, so that rock debris can be quickly and effectively removed from a drill hole, and the rock debris is prevented from being accumulated at the bottom of a drill bit to reduce the rock breaking efficiency; meanwhile, friction between the drill bit and rock is reduced, abrasion of the drill bit is reduced, and the drilling effect of the drill bit is improved.
