FEATURES
- High operating rotating speed, large axial-load cutting drilling system were designed,which based on the working requirement related to soft rock. Matching medium or low pressure compressor to achieve drilling demand which need to be faster and more economic.
- It has a high drilling frame structure and four-point hydraulic expansion leg suitable for large-scale mining,which has excellent ground adaptability.
1.Cab of full hydraulic surface down-the-hole drilling rig
The cab provides safe operation environment for operators,intensive design of electronic buttons and hydraulic handles with reasonable layout.
2.Automatic rod change device of full hydraulic surface down-the-hole drilling rig
The automatic drill rod library is equipped with bionic manipulator and rotary drill rod storage. An operator can complete the work of changing rods and drilling holes, reducing the difficulty of
operation, saving labor, to achieve the high efficiency and reliability performance.
3.Dust removal system of full hydraulic surface down-the-hole drilling rig
Two-stage dry dust removal system or high-pressure water dust removal system can effectively reduce dust and maintain a clean working environment.
4.Two-stage screw compressor of full hydraulic surface down-the-hole drilling rig
Can be equipped with a variety of international brands(Sullair, Airman, Sullivan Palatek, Doosan, Gardner Denver...)of two-screw compression host, to ensure a higher impact frequency, and a good slag effect.
