Research and Development of Multi-Function Excavator Drill with Hydraulic Rotary Cutting and Pneumatic Impacting

Abstract:

To solve the existing shortage of cutting drill, a multi-function excavator drill with hydraulic rotary cutting and pneumatic impact was invented on the base of market investigation, which is suitable for different rocks because of combining hydraulic rotary cutting with pneumatic impacting. If working on the soft rock, the new drill will turn off the pneumatic rock drill, replace the drill bit and only operate with the rotary power head, while on the hard rock it will operate efficiently with the rotary power head and the pneumatic rock drill. The new drill has many features, such as compact structure, the capacity of meeting a variety of drilling requirements, wider operating range, lower energy consumption, higher drilling efficiency, comfortable and flexible operation, and lower cost.
