Jdl-280 Crawler Mounted Mechanical Top Drive Mud Rotary Drill Equipment/Pneumatic DTH Bore Water Well Drilling Rig Machine

Product Description

Product Description JDL-280 mud/air drilling rig is a water well drilling rig that mix mud drilling rig and air drilling rig in one equipment with mechanical top head. It is a good solution to the difficulty of drilling in the soil layer for DTH rig and the low efficiency of drilling for mud rotary rig in the hard rock, gravel and pebble layer. The mud/air drilling rig adapts to various soil strata. The mud/air drilling rig is efficiency and energy saving to drill water well and geological exploration of core sample.
1. The drilling rig is equipped with a hydraulic drill tower, hydraulic supporting legs, winch, and the top drive power head can slide up and down;
2. Rubber tracks are standard, but can also be upgraded to steel tracks for better off-road capability;
3. Automobile gearbox shift mechanism, durable, shift more easily;
4. The drilling rig adopts double oil pump for oil supply. When drilling, it uses single pump, and when lifting drill rods, it uses double pump to merge; the power loss is small and the auxiliary time is short;
5. The main shaft of the drilling machine adopts mechanical transmission;
6. Some functional interfaces are reserved in the hydraulic control system of the drilling rig.
