Product description information

This product is an open-pit DTH drilling rig integrating heavy gas collection, liquid and automatic control of independently developed and manufactured by Zhejiang Zhigao Machinery Co., Ltd。 It comes standard with cab and automatic brazing mechanism, heavy-duty travel mechanism and chassis with leveling function, which meets the requirements of fast movement and high off-road performance, while smoother rock drilling. Equipped with dual-stage dust removal function can meet the environmental protection requirements of all mines, and the products are widely used in various engineering construction and mining. Products with high efficiency, energy saving, environmental protection and safety characteristics are widely selected by modern green mines.

Main features: large aperture, medium and deep holes, adapt to various complex rock formations.

Efficient

Automatic brazing and drill pipe up to 6 meters and powerful off-road performance reduce rig assist times. Equipped with a large-displacement high-pressure screw air compressor makes the slag discharge thorough, which is more conducive to the significant increase of rock drilling speed and reduces the consumption of drilling tools. The large diameter drill pipe reduces the compressed air required for slag removal. The powerful propulsion and slewing design solves the problem of jamming of complex rock formations on the basis of satisfying high-speed rock drilling. One-man operation reduces labor costs, and large bore drilling reduces the number of holes required. The above features also reduce the number of equipment required in the mine.

Energy saving

A single engine drives both the screw compressor and the hydraulic system, and the power output is designed to be staggered, which reduces the total power by about 30% and the maintenance cost by 50% compared to the split rig diesel engine. The reduction in total power consumption, the increase in drilling speed and the reduction in auxiliary time and the number of drilled holes result in a significant reduction in energy consumption per unit.

Eco-friendly

The standard two-stage dry dust collection device and optional wet dust removal device not only solve the environmental protection needs of mines and operators, but also greatly reduce the pollution of dust to the equipment itself.

Security

The crawler leveling device makes the center of gravity of the drilling rig uphill and downhill more stable, the crawler adhesion of the original terrain is stronger, the strong operating capacity reduces the number of equipment and personnel required by the mine, and the protection design of the bunker and cab eliminates the potential safety hazards of personnel.

Product features

1. Select special steel according to requirements, adopt advanced structural manufacturing technology.
2. Floating tubing and pipe follower: The configuration of the floating tubing and pipe follower independently developed by Chigo effectively protects the hydraulic pipeline and air pipeline, and greatly prolongs the service life.
3. Brazing mechanism: the patented design of sensing positioning brazing silo, manipulator, lock sleeve and caliper composed of brazing mechanism to meet the brazing needs of various specifications of drill pipe.
4. Advanced positioning jamming mechanism: efficient positioning device makes accurate positioning, and the safety design of the clamping device eliminates the hidden danger of falling drill pipe.
5. High-power slewing mechanism: enlarged design of the rotary head, can achieve stable large torque output, overcome the problem of jamming and has stepless speed regulation function. The swivel seat is located between the rails and is equipped with special wear-resistant pads for easy clearance adjustment.
6. Humanized and comfortable high-safety cab, in line with the top protection standards of European and American labor safety.
