Product Description Information
This product is independently developed and manufactured by Zhejiang Zhigao Machinery Co., Ltd. It features heavy-duty gas, liquid collection, and automatic control. Integrated open-air down-the-hole drill rig. It comes standard with a cab and an automatic rod changing mechanism, as well as a heavy-duty traveling mechanism and chassis with leveling function, ensuring fast movement and high off-road performance while providing a smoother rock drilling experience. Equipped with a dual-stage dust removal function, it meets all environmental protection requirements for mines. The product is widely used in various construction projects and mining operations. With its high efficiency, energy saving, environmental friendliness, and safety features, it is widely chosen by modern green mines.
Efficiency
The automatic rod changer, drill rods up to 6 meters long, and strong off-road performance reduce the auxiliary time of the drill rig. Equipped with a high-displacement high-pressure screw air compressor, it ensures thorough slag removal, which is more conducive to significantly increasing drilling speed and reducing the consumption of drilling tools. The large diameter drill rod reduces the compressed air required for slag removal. The powerful propulsion and rotation design, while meeting the requirements of high-speed drilling, solves the problem of drill jamming in complex rock formations. Single-person operation reduces labor costs, and large-diameter drilling reduces the number of required drill holes. The above functions also reduce the number of equipment required for mining.
Energy conservation
A single engine simultaneously drives both the screw air compressor and the hydraulic system, with power output designed for peak shaving. Compared to a split-type drill diesel engine, the total power output is reduced by approximately 30%, and maintenance costs are reduced by 50%. The reduction in total power consumption, increase in drilling speed, shortening of auxiliary time, and decrease in the number of drill holes have significantly reduced unit energy consumption.
Environmental Protection
The standard dual-stage dry dust collection device and the optional wet dust removal device not only meet the environmental protection needs of mines and operators, but also significantly reduce the pollution of dust to the equipment itself.
Safety
The track leveling device stabilizes the center of gravity of the drill rig when going up and down slopes, enhances the track adhesion to the original terrain, and reduces the number of equipment and personnel required in mines due to its powerful operational capacity. The protective design of the tool magazine and cab eliminates potential safety hazards for personnel;
Product Features
1. Select special steel materials as required and adopt advanced structural manufacturing processes.
2. Floating tubing follower: The configuration of the floating tubing follower, independently developed by Zhigao, effectively protects hydraulic and air pipelines, greatly extending their service life.
3. Rod Changer: The patented design of the rod changer, consisting of a sensor-positioned rod chamber, robotic arm, locking sleeve, and rod clamp, meets the rod changing requirements for various specifications of drill rods.
