KT20 Integrated Surface DTH Drilling Rig
Drilling diameter:135-190 mm
Drilling depth(depth of automatic extension rod):35 m
Displacement of screw compressor:22 m³/m
Discharge pressure of screw compressor :20 bar
Quantities can be customized
1. Disc type auto rod-loading system is used and auto rod-loading can reach the depth of 35m.
2. Equipped with amplitude mechanism, the carriage has total swing angle of 130° (97° to the right and 33° to the left) to freely complete horizontal and vertical holes transition without changing pivot. The lowest elevation horizontal hole is 550mm and the highest elevation is 4,200mm.
3. It adopts Caterpillar electronic fuel injection engine to provide high power and reliable performance.
4. Single engine with two-end output is configured to provide compact structure and convenient maintenance.
5. High wind pressure large-displacement air compression system (22 ³/min, 20 bar) guarantees fast drilling of the hammer.
6. Automatic leveling function of the travelling mechanism enables the drilling rig to be more adapted to rugged mountain roads in the mine.
7. Double rod lifting mechanism guides the rig all the way to prevent deflection in the drilling process (It guides the hammer during trepanning and the drill rod during drilling).
8. The drilling rig adopts imported hydraulic parts and electric appliance.
