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