Product description information
This product is an open-air down-the-hole drill developed and manufactured by Zhejiang Zhigao Machinery Co., Ltd., featuring heavy-duty gas, liquid, and automatic control integration. It comes standard with a cab, an automatic rod changing mechanism, a heavy-duty traveling mechanism with leveling function, and a chassis, ensuring rapid movement and high off-road performance while providing stability during rock drilling operations. 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. Due to its high efficiency, energy saving, environmental friendliness, and safety features, it is widely chosen by modern green mines.
Main features: large aperture, medium-deep hole, suitable for various complex rock formations.
Efficiency
The automatic rod changer, drill rods up to 6 meters long, and robust 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 conducive to significantly increasing the drilling speed and reducing the consumption of drilling tools. The large diameter drill rods reduce 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. These features also reduce the number of equipment required in mines.
Energy saving
A single engine simultaneously drives both the screw air compressor and the hydraulic system, with its power output designed for peak load shifting. Compared to a split-type drill rig 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, shortened auxiliary time, and decreased number of drill holes have significantly reduced the 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 its powerful operational capability reduces the number of equipment and personnel required in mines. 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 the 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 magazine, robotic arm, locking sleeve, and rod gripper, meets the rod changing needs of various specifications of drill rods.
4. Advanced positioning and clamping mechanism: The efficient positioning device ensures precise positioning, and the safety design of the clamping device eliminates the risk of falling drill rods.
5. High-power rotary mechanism: The enlarged rotary head design enables smooth high-torque output, overcomes the problem of tool jamming, and features stepless speed regulation. The rotary base is located between the guide rails and is equipped with a specially made wear-resistant pad, making gap adjustment convenient.
6. The ergonomically designed and highly safe driving cab meets the top protection standards for labor safety in Europe and the United States.
