JDL-350 Crawler Mounted Top Drive Rotatory Mineral Exploration Wireline Core Drilling Machine
1. Brief introduction of JDL-350 mechanical top drive core drilling rig
JDL-350 drilling rig is a mechanical top-drive drilling equipment that integrates water drilling and gas drilling, which solves the difficulty of drilling air-drilling hammers in soil layers. The problem of low mud drilling construction efficiency, the dual-purpose water and gas drilling rig is suitable for various formations, and the core drilling efficiency and geological exploration are efficient and energy saving.
2. Features of JDL-350 features of mechanical top drive core drilling rig
(1) Equipped with hydraulic steel tracks for stronger off-road capability;
(2) Equipped with four hydraulic square tube high outriggers, which is convenient For leveling on site and saves a lot of loading and unloading costs;
(3) The left and right of the rig are equipped with drill rod holders and foot pedals, which are more user-friendly in design;
(4) The front end of the drilling rig is equipped with an auxiliary rod unloading cylinder, which makes it easier to loosen the drill rod;
(5) The hydraulic oil pump is directly connected to the power by a universal shaft, which makes the rig climbing and moving more powerful;
(6) AMT manual automatic transmission with electronic transmission and electronically controlled shifter make shifting easier;
(7) The rig uses dual oil pumps to supply oil, and the hydraulic system uses split flow and merge technology to increase and decrease the power head more quickly;
(8) Equipped with a foldable auxiliary tower, which can lift two 3 m / drill drill rods at a time.
