Product Description Information
This product is a heavy-duty open-air down-hole drilling rig developed and manufactured by Zhejiang Zhigao Machinery Co., Ltd., which integrates gas, liquid, and automation control. It comes standard with a driver's cab and an automatic tool changing mechanism, as well as a heavy-duty walking mechanism and chassis with leveling function, which not only meets the requirements of fast movement and high off-road performance, but also makes rock drilling operations more stable. Equipped with dual level dust removal function, it can meet the environmental requirements of all mines, and the product is widely used in various engineering construction and mining. The product is widely selected by modern green mines for its high efficiency, energy conservation, environmental protection, and safety characteristics.
Main features: large aperture, medium depth hole, suitable for various complex rock formations.
Efficient
The automatic replacement of drill rods, a maximum length of 6 meters of drill rods, and powerful off-road performance shorten the auxiliary time of the drilling rig. Equipped with a large displacement high-pressure screw air compressor, the slag discharge is thorough, which is more conducive to a significant increase in drilling speed and reduces drilling tool consumption. The large diameter drill pipe reduces the compressed air required for slag removal. Powerful propulsion and rotation design, while meeting the requirements of high-speed rock drilling, has solved the problem of drilling stuck in complex rock formations. Single person operation reduces labor costs, while large hole drilling reduces the number of required boreholes. The above functions also reduce the number of equipment required for the mine.
energy conservation
A single engine drives both the screw type air compressor and hydraulic system simultaneously, and the power output is designed to be staggered. Compared to the diesel engine of a split drilling rig, the total power is reduced by about 30%, and maintenance costs are reduced by 50%. The decrease in total power consumption, the increase in drilling speed, the shortening of auxiliary time, and the reduction in drilling quantity result in a significant reduction in unit energy consumption.
environment protection
The standard dual stage dry dust collection device and optional wet dust removal device not only meet the environmental protection needs of mines and operators, but also significantly reduce the pollution of dust on the equipment itself.
security
The track leveling device makes the center of gravity of the drilling rig more stable on the uphill and downhill slopes, and the track adhesion of the original terrain is stronger. The powerful operation ability reduces the number of equipment and personnel required for the mine. The protection design of the drill bin and driver's cab eliminates personnel safety hazards& Nbsp;
