Embodiment Construction
[0024] Such as figure 1 As shown, the present invention is used in deep wells, ultra-deep wells, and hard rock drilling. The three-in-one combined core drilling tool includes a rope fisher 1 placed on the surface, an outer pipe assembly 2, an inner pipe assembly 3, a screw rod Motor 4, hydraulic down-the-hole hammer 5, core holding pipe 6, drill bit 7 and corresponding positioning mechanism II, torque transmission mechanism III, flushing fluid diversion mechanism IV, outer tube single-action mechanism V, impact energy transmission mechanism VI, radial Fine-tuning mechanism VII. When the drilling tool is working at the bottom of the well, the upper drilling tool does not rotate, but uses the flushing fluid to drive the rotor of the screw motor 4 to rotate, and the output shaft of the screw motor transmits power to the lower drilling tool through the torque transmission plate 32 and drives the drill bit 7 to rotate . After the flushing fluid discharged from the screw motor 4 i...
