- Drill string (rods and bit)
Working Principle
The Kaishan KG590H operates on the principle of down-the-hole (DTH) drilling, where a pneumatic hammer is positioned directly behind the drill bit. High-pressure air is supplied through the drill string to drive the hammer's piston, which strikes the bit with rapid impacts. Simultaneously, the rotary head rotates the drill string, indexing the bit for efficient rock fragmentation. The cuttings are flushed out of the hole by the exhaust air, ensuring a clean hole. The hydraulic feed system applies optimal pressure on the bit, while the crawler chassis provides stability and mobility. This combination of impact and rotation allows the KG590H to achieve high penetration rates in hard rock formations with minimal deviation.
