Kaishan Surface Drilling Rigs/KD Series DTH Drill Rig
KD70
The KD70 is a Kaishan KD-series surface down-the-hole drilling rig with a 152–203 mm drilling-diameter specification. Its stated rock-hardness range is f=6–20. The power package uses Cummins QSZ13-500–30. The screw-compressor specification is two-stage compression; 31 m³/min at 25 bar. The feed system uses motor + roller chain. Dust removal uses dry hydraulic cyclonic laminar flow; wet system optional. Rod handling: Automatic rod changing. Anti-jamming: Electro-hydraulic anti-sticking control. Drill-rod lubrication: Automatic oil-injection lubrication. Drill-rod thread protection: Floating joint protects the rod thread. Drilling display: Real-time drilling-angle and depth display. Cab protection: Meets FOPS and ROPS protection requirements.
