HQD70 electric down-the-hole drilling rig

D-type electric down-the-hole drilling rig
D-type electric down-the-hole drilling rig is a new type of rock drilling equipment with high efficiency and wide applicability. It is widely used in small and medium-sized mines and transportation, national defense, water conservancy, stonework and other projects. It is especially suitable for Rugged terrain where other drilling rigs cannot operate properly. The machine has a simple structure, easy operation, low price, saves energy, and has the function of drilling vertical and horizontal holes. In particular, the machine has a low center of gravity, good disassembly, and is extremely convenient for relocation and transportation.
Main Features
● Simple structure, easy operation, low price
● Low center of gravity, good detachability, easy to relocate and transport, especially suitable for rugged terrain or primitive landforms
● Impactor Low air consumption, small exhaust volume of air compressor required for matching, energy saving and economical
● The rotary reducer has large torque and good reliability under strong vibration and high load working conditions.
● The electrical system has overload protection and phase loss protection functions to ensure stable and reliable operation of the drilling rig.
● The propulsion system is equipped with a pressure reducing valve to adjust the propulsion force according to different rock conditions to obtain the best rock drilling effect.
