Product Description Information

This product is a heavy-duty surface潜孔钻机 that integrates gas and liquid collection and automatic control, independently developed and manufactured by Zhejiang ZhiGao Machinery Co., Ltd. It is equipped with a cab and an automatic drill bit changing mechanism, a heavy-duty walking mechanism and chassis with leveling function. It not only meets the requirements of rapid movement and high off-road performance, but also ensures stability during rock drilling operations. It is equipped with a dual-stage dust removal function to meet the environmental protection requirements of all mines. The product is widely used in various engineering construction and mining operations. With its characteristics of high efficiency, energy saving, environmental protection and safety, it is widely chosen by modern green mines.

Main features: large aperture, medium deep hole, adaptable to various complex rock strata.

High Efficiency

Automatic bit changing, drill rods up to 6 meters in length, and powerful off-road performance reduce the auxiliary time of the drilling rig. The large-displacement high-pressure screw air compressor ensures thorough rock debris removal, which is conducive to a significant increase in drilling speed and reduces the consumption of drilling tools. The large-diameter drill rods require less compressed air for rock debris removal. The powerful thrust and rotation design not only meets the requirements of high-speed drilling but also solves the problem of stuck drill bits in complex rock strata. Single-person operation reduces labor costs, and large-diameter drilling reduces the number of required drill holes. All these features also reduce the number of equipment units needed in mines.

Energy Saving

A single engine simultaneously drives the screw air compressor and the hydraulic system, and the power output is designed to be off-peak. Compared with the total power of the diesel engines of the split-type drilling rig, it decreases by approximately 30%, and the maintenance cost drops by 50%. The reduction in total power consumption, the increase in rock drilling speed, the shortening of auxiliary time, and the decrease in the number of drill holes have significantly lowered 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 ensures a more stable center of gravity for the drilling rig when going up and down slopes, and enhances the track's grip on the original terrain. The powerful operating capacity reduces the number of equipment and personnel required in the mine. The protective design of the drill magazine and the cab eliminates potential safety hazards for personnel.

Product Features

1. Special steel is selected as required and advanced structural manufacturing processes are adopted.
2. Floating Tubing Guide: The floating tubing guide independently developed by ZhiGao effectively protects the hydraulic and air pipelines, significantly extending their service life.
3. Bit-changing mechanism: The bit-changing mechanism, which is composed of a patented designed sensor-located bit storage, mechanical hand, lock sleeve and bit clamping device, meets the bit-changing requirements of various specifications of drill pipes.
4. Advanced positioning and drill pipe clamping mechanism: The efficient positioning device ensures precise positioning, and the safety design of the drill pipe clamping device eliminates the risk of drill pipe dropping.
5. High-power rotary mechanism: The enlarged design of the rotary head enables smooth high-torque output, overcomes the problem of stuck drill rods, and features stepless speed regulation. The rotary seat is installed between the guide rails and is equipped with specially made wear-resistant pads, allowing for convenient gap adjustment.
6. The highly safe cab with humanized comfort design complies with the top protection standards for labor safety in Europe and America.
• Wide, clear and environmentally friendly glass with a broad field of vision;
• The all-round visible range, low vibration and low noise design achieve the best comfort.
• The standard configuration of audio and air conditioning systems enables operators to enjoy their work with ease.
• The control system is easy to operate and highly operable, and is simple to learn.
• Various display, prompt and alarm functions ensure that the equipment always remains in the best working condition.
7. Dry and wet dust collection systems: Standardly equipped with a two-stage high-efficiency dry dust collector, and a wet dust collector is available as an option. The technology is advanced and leads industry standards.
