KQY90 down the hole driller

 

Down the hole drill series is in accordance with the innovative design of the mine characteristics, with novel structure and high efficiency energy saving. It is widely used in small and medium-sized mines, defense engineering, water conservancy, road construction, blast hole drilling operations in rock engineering, which is ideal machine to achieve hierarchical extraction and medium deep-hole blasting. To achieve high efficiency energy- saving, the hydraulic design of technological innovation is applied to the light down the hole drill. It adopts the cycloidal gear reducer with large torque to meet high efficiency drilling. The compressed air offers power for advancing, rotating and impacting. It’s simple structure, individual power and easy to move. The unique dual-muffler can do effective muffler to reduce the environmental pollution.
