"Kaishan" KT20 open-pit DTH drilling truck is a new type of well-designed drilling equipment for large open-pit mines based on the development and production of DTH drilling trucks by Kaishan Group for many years. The drilling rig adopts hydraulic drive, strong power, high air pressure screw head and high air pressure pneumatic impactor, high drilling efficiency, equipped with hydraulic dry dust collector to collect dust and reduce environmental pollution, and equipped with hydraulic manipulator and drill pipe depot to remove and remove drill rods and float. Joints protect drill pipe threads, one person can remove drill pipe; air-conditioned cab provides a comfortable working environment and automatic control of anti-sticking valve to reduce the rate of sticking. The drilling rig has the characteristics of good integrity, high degree of automation, good rock drilling effect, environmental protection and energy saving, easy operation, flexible maneuvering and safe driving.
1. disc type automatic connecting rod system, automatic connecting rod drill depth can reach 36 meters.
2. The swing angle of the sliding frame adopts a luffing mechanism with a total swing angle of 130 degrees (right 97 degrees left 33 degrees). The swing between horizontal and vertical holes can be completed freely without changing fulcrum. The minimum horizontal hole height is 550mm, the highest is 4200mm.
3. the Caterpillar EFI engine has strong power and reliable performance.
4. the single engine output is arranged at the two ends, with compact structure and convenient maintenance.
5. high air pressure and large displacement air compression system (22m3/min, 25bar) ensures fast drilling of impactor.
6. the automatic leveling function of the running mechanism makes the drilling car more suitable for the rough mountain road of the mine.
7. Double bracing mechanism guides the drilling tool throughout the drilling process to prevent deviation when drilling (guides the impactor when drilling holes, guides the drill pipe when drilling holes).
8. imported hydraulic parts and electrical appliances.
