Applications:1. In the exploration of mineral resources, relatively complete and unmixed stratum rock samples are taken out. It can be used for construction in mine roadway or in landmark construction. The operation is concentrated, simple, labor-saving and safe. Good disassembly performance, easy to disassemble and relocate.The structure is compact, safe and convenient, and can be drilled at any angle. 2. Hydrogeological survey before production prospecting and roadway excavation, and water hole exploration. For example,the construction of water detection holes and water discharge holes in the roadway is equipped with professional water-stop casings and valves, which are resistant to high pressure. Fast, efficient and low-cost detection of geological conditions and hydrological conditions in front of the roadway,reducing unnecessary roadway construction, effectively reducing the risk of water penetration, and reducing safety accidents. 3. Engineering geological survey, hydrogeological survey. Hydrogeological survey before the construction of railway and highway tunnel projects, quickly, efficiently and at low cost to find out the geological conditions and hydrological conditions ahead of the roadway. Improve engineering efficiency and reduce construction risks. 4. Grouting holes for special purposes in engineering, geological survey holes, etc.

Features:1. The spindle is driven by a manual variable motor to rotate, with a wide adjustment range and stable work. Suitable for diamond high-speed drilling, also suitable for carbide low-speed drilling rigs. 2. Centralized, simple, labor-saving and safe operation. 3. Good disassembly performance, easy to disassemble and relocate. 4. Compact structure, easy installation, can drill holes in 0°~360°azimuth. 5. The hydraulic transmission controls the chuck, the holder and the feed cylinder to make the pulling drilling tool linkage. The mechanical torsion tube has a high degree of mechanization, which greatly reduces the labor intensity of workers. 6. The hydraulic system adopts the multi-pump dual-system oil supply design, and the power matching of the drilling rig is reasonable.
