Design of Lubrication and Cooling Flushing Mechanism for Hand-held Pneumatic Rock Drill

Abstract

The advantages and disadvantages of the traditional lubrication and cooling mechanism of Air-leg Rock drill are analyzed. In order to solve the shortcomings of the traditional structure and the fatal disadvantages of gas-water linkage failure and hammer washing, a new lubrication and cooling mechanism of Air-leg Rock drill is designed. It prevents the backfilling of pneumatic rock drill in the normal working process and at the end, improves the life of pneumatic rock drill as a whole, and has been verified in the customer site, and achieved good results.
