The problems existed in the lubricating and cooling mechanism of conventional pneumatic rock drill were analyzed.In order to solve the shortcomings of airwater linkage failures and “wash hammer” of conventional pneumatic rock drill,a new technical solution was proposed for the lubricating and cooling mechanism of pneumatic rock drill.The implementation method of the new lubricating and cooling mechanism of pneumatic rock drill was given.The new lubricating and cooling mechanism improves the lubrication and cooling effect of pneumatic rock drill,prevents the intrusion of gas and water during working process and at the end of working,and prolongs the service life of pneumatic rock drill.
