ABSTRACT:
The present invention is for an improved feed shell for an air-flushing, rock-drilling system. The improvement extends the life of the feed shell and, in particular, the feed guide of a feed shell on which gibs for directing a rock drill ride. The system, as improved, provides a first nozzle which directs fluid onto a first guide surface of the feed guide and second nozzle which directs fluid onto a second guide surface of the feed guide. The nozzles can be mounted in either manifolds or, alternatively, in the gibs which support and guide the drill on the feed guide.
