| description | The invention discloses a quarrying drilling device for outcrop hard rocks, which comprises a sleeve, a plurality of mounting holes are formed in the outer part of one side of the sleeve, and fastening bolts are in threaded connection with the interiors of the plurality of mounting holes. When the device is used, the sleeve is installed at the output shaft end of a drilling machine and is further fixed through the fastening bolt, then the first connector and the second connector on one side of the sleeve are connected, locking is conducted through the locking mechanism during connection, the position of the installation mechanism and a drill rod are assembled after locking, and then the drill rod is installed. When drilling is conducted, resistance borne by the drill rod is transmitted to the position of the limiting mechanism through the second connector, the limiting mechanism and the second connector bear torsion at the same time, abrasion between the second connector and the drill rod can be reduced, vibr |
