| titleOfInvention | Piston Hammer Drilling Type Hammer Drill Compound Drilling Rig |
| abstract | The invention discloses a piston-hammer drill-in type hammer-drill compound drilling rig, which relates to the technical field of drilling rig equipment. It includes a connecting cylinder, a hammer body and an auger bit; the hammer body is slidably connected with the inner wall of the connecting cylinder, and the hammer body is a cavity structure; a connecting piston is slidably installed in the hammer body; the connecting piston is fixedly connected with a support drill; the connecting cylinder and the hammer The bodies are respectively connected with the air compressor; the auger bit includes a connecting shaft and a guide vane; the connecting shaft is fixedly connected with the hammer body; The beneficial effect of the invention is that the auger bit is protected by monitoring the stratum environment through the torque sensor, so when the stratum environment is soft, the auger bit rotates to drill, and after the stratum environment is hardened, the support drill supports and reinforces the auger bit to prevent the auger bit. Rock and other hammers are used for hammer drilling operations, so when drilling operations in different strata environments, it is avoided to replace the drill bit, improve drilling efficiency, and be more flexible and convenient to use. |
