Introduction to pneumatic column drilling rig

‌Pneumatic column drilling rig‌ is a drilling equipment that uses compressed air as a power source. It is widely used in coal mine water exploration, gas exploration, tunnel anchor hole construction and other operations.
Pneumatic column drilling rigs have the advantages of safety and explosion-proof, large torque, high speed, small size, light weight, simple structure, and easy disassembly and assembly. After disassembly, each component is less than 50 kg. The main engine rotation of the pneumatic column drilling rig has forward and reverse functions, which can easily drill and push out the drilling tools; the feed adopts an independent motor with large feed force and low failure rate; the rotation speed and feed speed can be adjusted by controlling the air intake. This series of drilling rigs can be equipped with high-efficiency spiral drill rods and geological drill rods, and are widely used in drilling construction for coal mine water exploration, water injection, gas exploration and drainage, pressure relief holes, tunnel side anchor holes, etc.
