A new type hydraulic rotary cutting and pneumatic impacting rock drill is used to drill medium and deep hole. This rock drill is made up of three components: impact system, rotary system and dedust mechanism. The power is provided by hydraulic liquid and compressed air, and the hydraulic power is separated with the pneumatic power. The rotary system driven by hydraulic liquid transfers motion and force by its components: motor, input gear, mid-gear, revolving sheath, etc. The maximum rotary power is greater than the impact power. Compared with other drill, this new rock drill has a simple structure, high reliability, fast drilling speed, long service life of the drilling tools, easy maintenance, high performance-price ratio and other advantages
