"Zhongtuo" brand KT5-type open-air DTH drilling rig is an advanced drilling equipment that integrates the downhole drilling system and the screw air compression system. It has compact structure, good integrity and easy movement. The drill has energy-saving efficient, safe and environmentally friendly, flexible, easy to operate, stable performance and so on. Specific performance is as follows:
1, compact structure of the drill car, open-hole drilled hole drills and stroke pressure screw machine organic combination.
2, The rig equipped with single-stage stroke pressure screw host, flow (10m3 / min), pressure (1.5MPa), the use of stroke pressure pneumatic impact, high efficiency, low energy consumption.
3, the low center of gravity and balanced distribution of the drill, equipped with heavy "four rounds and a" 19 ° automatic leveling device and dual control system can be independently controlled to improve the stability of the machine to adapt to different conditions. The drill equipped with a two-speed travel motor + reducer structure, to achieve the perfect combination of speed and power.
4, large displacement hydraulic pump installed directly on the engine after the take-off port, simple structure to reduce the source of the fault.
5, large-scale luffing boom system to meet the needs of different working conditions in various conditions, in particular, can play low horizontal hole.
6, highly integrated hydraulic control system and layout of the centralized operating platform, a station can freely manipulate the entire machine.
7, the drilling rig configuration rotary speed control valve, according to different characteristics of the rock being drilled and different conditions, can be adjusted in time, drilling speed, high porosity.
8, the machine is equipped with real-time monitoring system and a stable self-protection system, can accurately reflect and control the working status of the drilling car, beyond the set range and failure can automatically shut down.
Efficient two-stage dry dust collection system, greatly improving the working environment, in line with the concept of energy saving and environmental protection.
