The application discloses a rock drilling mechanism with a guide structure, which comprises a supporting mechanism and a drilling
assembly arranged inside the supporting mechanism; the supporting mechanism comprises a
chassis and a top plate on the top of the
chassis, and a guide mechanism is arranged on the
chassis; the guide mechanism comprises a guide
assembly arranged directly below the drilling
assembly and sleeved outside the output end of the drilling assembly; a connecting assembly is composed of a mounting piece and a supporting piece, one end of which is detachably fixed with the guide assembly and the other end is detachably fixed with the top end surface of the chassis; through the designed guide mechanism, the position of the
drill rod can be limited, corrected and guided, so that the
drill rod can rotate around its own axis in rotation, the problem that the bottom of the
drill rod swings greatly and affects the
processing efficiency and quality is avoided, and when the rotation of the drill rod is not deviated, the risk of breakage of the drill rod is also reduced.
