1. Introduction of JDL Series Mechanical Top Drive Core Drilling Rig JDL series drilling rig is a mechanical top drive drilling equipment integrating water drilling and air drilling, which can effectively solve the problems of difficult drilling of air down-the-hole hammer in soil layer and low efficiency of water drilling mud drilling in hard rock layer, gravel and pebble layer. Mechanical top drive drilling rig can adapt to various strata, with high drilling efficiency and energy saving. 2. Features of JDL series mechanical top drive core drilling rig 1. It realizes the functional integration of mud drilling and pneumatic down-the-hole hammer drilling. 2. Some functional interfaces are reserved in the hydraulic control system of the drilling rig, and the functions can be expanded according to the process requirements of different users. 3. The main shaft of the drilling rig adopts mechanical transmission, which doubles the transmission efficiency and greatly reduces the power energy consumption. 4. The drilling rig adopts mechanical top drive power head and long-stroke speed mechanism to improve drilling efficiency and reduce the occurrence of drilling blockage and drilling burning accidents. 5. The drilling rig adopts mechanical winch, which has a fast lifting speed and is convenient for handling bottom accidents. III.
