Design of Mine-used Dry-type Pneumatic Drill

In this article, a new mine-used hand-held pneumatic drill is developed. The drill can be widely used for underground borehole, nut pre-load, stirring and other aspects. This drill takes pneumatic as power source which is safe and reliable; its dust collection device adopts vacuum type and uses high pressure gas from drill outlet to collect dust; so it is energy-saving and environmentally friendly. The drill has the advantages of convenient operation, simple structure, safety, high efficiency, light weight, convenient repair and maintenance.
