The integrated hydraulic downhole drilling rig is widely used in metallurgical, mining, building materials, railway, hydropower construction, national defense construction and earth works, and the blasting hole drilling of open construction. It takes hydraulic drive for track traveling, rotary drill tool forward, drill tower top lifting compensation and drilling rig leveling. It takes compressed air from screw-type air compressors to impact drilling and flush the hole, with air pressure range of 1.05-1.4 M Pa, and dry-type distribution laminar precipitator. The drilling tool takes Ingersoll-Rand high-pressure downhole impactor, with the drilling aperture of 90 ~ 180 mm, and the depth of 30 m vertical or inclined hole. It is the most advanced integrated hydraulic downhole drilling rig in China, with the feature of highly-efficient high pressure downhole drilling system, which facilitate to drill the blasted hole with high-precision and high efficiency. Global purchase, optimal design with the computer, power matching and the development and application of load applicable system contribute to the realization of the overall power load matching from power-pump -load in the power system, which effectively reduces the overall energy consumption and ensures the best performance and the overall high reliability.

 ·Integration of drilling rig, air compressor and hydraulic pump group provide improved maneuverability, energy saving, and high efficiency.
·Pilot handles control all the machine operations, air-conditioned & auto-boosted cabin prevent dust entry and improve the working enviro nment. Easy-to-read monitor panel enable perator light-hearted operation.

·High reliable crawler traveling system, hydraulic motor driving drilling rod, and hydraulic cylinder supported sliding rack optimize working efficiency and machine adaptability.

·Auto disassembly mechanism for impactor and drilling stem.

·Shock absorb spring mounted on rotary head to extend the service lifetime of rotary head.·Auto block-prevention mechanism can lift the drill stem automatically when the stem gots stuck.
·High effective dust collection device helps to maintain clean working environment.
·Reliable sliding rack mechanism adjusts the connection between  boom and working face.
·The swing mechanism is effective to the machine orientation to save auxiliary working time.
