35m depth kt25 Efficient dust collection system dth Blasting hole integrated mine drill rigs for open Use mining
KT25 open-pit down-the-hole drilling rig is a new type of drilling equipment carefully designed for the needs of large open-pit mines on the basis of years of development and production of down-the-hole drilling rigs by Kaishan Group. The drilling rig’s walking, propulsion, rotation and angle adjustment are all driven by hydraulic pressure, with strong power; Equipped with high wind pressure screw head and high wind pressure pneumatic impactor, the drilling efficiency is high; Equipped with hydraulic dry dust collector to collect dust, reducing environmental pollution; It is also equipped with a hydraulic manipulator, a drill pipe library to disassemble the drill pipe and a floating joint to protect the thread of the drill pipe, so that one person can disassemble the drill pipe; The air-conditioned cab provides a comfortable working environment and automatically controls the anti-sticking valve to reduce the drilling rig sticking rate. The drilling rig has the characteristics of good integrity, high degree of automation, good drilling effect, environmental protection and energy saving, convenient operation, flexibility and safe driving.
1. Disc-type automatic tappet connecting system, the drilling depth of automatic tappet connecting can reach 35 meters.
2. The swing angle of the carriage adopts luffing mechanism, with a total swing angle of 130 (97 right and 33 left), and the conversion between horizontal hole and vertical hole can be completed freely without changing fulcrum. The lowest horizontal hole height is 550mm and the highest is 4200 mm.
3. Caterpillar EFI engine is adopted, which has strong power and reliable performance.
4. The arrangement of single engine output at both ends is adopted, with compact structure and convenient maintenance.
5. The high wind pressure and large displacement air compression system (263/min, 205ar) ensures the rapid drilling of the impactor.
6. The automatic leveling function of the walking mechanism makes the drilling rig more suitable for the rugged mountain road of the mine.
7. The double-drill-holding mechanism guides the drilling tool in the whole process to prevent deviation during drilling (guide the impactor when drilling, and guide the drill pipe when drilling).
8. Adopt imported hydraulic components and electrical appliances.
