| titleOfInvention | Rotary rock drill |
| abstract | The invention concerns a rotary rock drill which has a rotatable, axially immobilised leadscrew threaded through a feednut to which a drill head is connected. Drive and gearing means operate to rotate the leadscrew relative to the feednut so that the feednut advances linearly on the leadscrew. A linear drive transfer mechanism operates to transfer the linear advance of the feednut to a drill rod which is chucked to a spindle carried by the drillhead and which is parallel to and spaced apart from the leadscrew. A rotary drive transfer mechanism operates simultaneously to transfer rotation of the leadscrew to the drill rod during linear advance thereof. |
