Geological mineral exploration coring bit

The utility model discloses a geological mineral exploration coring drill bit which comprises a drill bit body, a cavity is formed in the inner wall of the periphery of the drill bit body, an action groove is formed in the bottom of the drill bit body, and the cavity is of a barrel-shaped structure and is in through connection with the action groove. The bottom and the upper side wall of the cavity are symmetrically and rotationally connected with first rotating shafts and second rotating shafts with the rotating center of the acting groove as the symmetry center, first synchronous wheels are welded to the two first rotating shafts, and second synchronous wheels are welded to the second rotating shafts. The first synchronous wheel and the second synchronous wheel are jointly sleeved with a synchronous belt, and cooling fans are welded to the ends, deviating from each other, of the two second rotating shafts. The driving gear drives the driven gear to rotate, so that the heat dissipation fan can rotate while t
