Positive circulation drilling rig

The positive circulation drilling rig uses drill rods to drive the pneumatic impactor and drill bit to rotate together. The piston of the pneumatic impactor is used to impact the drill bit and crush the ore rock. It is usually used in small and medium-sized mines to drill blast holes with a diameter of 80-250 millimeters The vehicle has a low center of gravity, making climbing smoother and safer, with strong adaptability. It adopts a new hydraulic technology, which has a large turning torque, smooth and fast propulsion and lifting. The control panel and operating handle are centrally controlled, making the operation simple. The operator can stand on the side of the main engine for drilling operations, improving the safety factor of the operation The main technical parameters of this product (LQ-300 crawler type positive circulation drilling rig) are as follows: maximum drilling depth of 100m-300m, maximum drilling diameter of 300mm, drill rod length of 2000mm-3000mm, maximum stroke of power head of 4600mm, drill rod diameter of 89mm/108mm, lifting force of 25T, turning torque of 10000NM, bearing method: hydraulic crawler type, walking speed of 3000km/h, climbing ability of 30 °, external dimensions of 3000mm * 1700mm * 230mm, and overall weight of 7000kg
