The KH106 Integrated DTH Drilling Rig is a heavy-duty, high-performance drilling solution designed for large-scale mining, quarrying, and hard rock blasting applications. Built for maximum power, stability, and durability, this model delivers strong drilling capability under demanding geological conditions.
The machine adopts a 7-series high-strength aluminum guide rail with stainless steel protective skin, ensuring a lightweight yet rigid structure with excellent wear resistance and long service life. Its optimized structural design enhances stability while maintaining excellent mobility in mining environments.
The KH106 is equipped with an electrically controlled automatic rod changing system, enabling fast and efficient rod connection and disassembly, significantly improving drilling efficiency and reducing manual labor intensity.
The power head pipeline system uses casing follower protection design, effectively reducing wear and extending service life, while adapting to complex and high-impact working conditions.
A large-stroke drill arm cylinder with precise positioning control provides flexible drilling angles, allowing the rig to adapt to different blasting and formation requirements.
Powered by a 206KW Yuchai diesel engine, the KH106 delivers strong and stable output performance. The new-generation two-stage compression screw air system ensures large air volume with low fuel consumption, improving both efficiency and operating economy.
Both the engine and air end are equipped with a dual-stage deep filtration system (desert air filter + mechanical alarm filtration assembly), ensuring clean air intake and reliable performance even in dusty mining environments.
A 14-core high-efficiency dust collection system ensures effective slag removal and significant dust reduction, supporting modern green mining standards.
