Abstract:
    An earthquake dry hole drilling machine, which is mainly used to solve the problem of hole-making cost of the existing high earthquake exploitation drilling machine , is characterized in that: the lower end of the drill stem (2) is in turn connected with crashing device (3), core drill (4), driving head (1), drill stem (2) and crashing device (3). On the side wall is designed with axial airway (5), outlet of airway (5) is corresponding to beneath the crashing and cutting blade (6) in crashing device (3), airway (5) is connected to pressure fan (11) via pipeline, vacuum device (9) and separation device (10) are in turn connected to driving head (1), drill stem (2), crashing device (3) and core drill (4) via pipeline. Said earthquake dry hole drilling machine is characterized in that its low cost of hole-making.
