HQD70 electric submersible 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, especially suitable for bumps that other drill trucks cannot work normally. Rugged terrain. The machine has the advantages of simple structure, convenient operation, low price
and energy saving. At the same time, it has the function of drilling vertical and horizontal blasting holes. In particular, the center of gravity of the machine has low detachability and is very convenient for relocation and transportation.
Simple structure, convenient operation and low price; The center of gravity is low and detachable, and the relocation and transportation are convenient. It is especially suitable for the rugged terrain or original landform of the bump; The air consumption of the impactor is low, and the required air compressor has a small amount of air displacement, which is 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 function, which makes the drilling machine run stably and reliably. The propulsion system is equipped with a pressure reducing valve that adjusts the propulsion force according to different rock conditions to obtain the best rock drilling effect.
