1. Introduction to KQZD-720 Down-the-hole Drilling Rig
The KQZD-720 down-the-hole drilling rig is an efficient and flexible open-pit crawler rock drilling equipment. It transmits impact energy to the drill bit through the impactor. The drill bit rotates at high speed while impacting the rock at high frequency. Compressed air discharges the drilled rock cuttings out of the hole, realizing the synchronous operation of "impact-rotation-slag discharge". The down-the-hole drilling vehicle has excellent mobility and off-road capability, adapts to all-terrain operations, and can quickly and flexibly transfer in complex terrain. It is mainly used in open-pit mine blasting holes, large-scale stone engineering, water conservancy and hydropower construction and other fields.The Jujiang down-the-hole drill rig is an efficient and reliable choice for hard rock deep hole operations
2. Features of KQZD-720 Down-the-hole Drilling Rig
2.1 It adopts steel track chassis and has good off-road performance.
2.2 Some models of crawler frames are equipped with pitch cylinders, which can freely adjust the center of gravity of the vehicle body to ensure stability and safety when drilling on uneven terrain.
2.3 The drill arm and drill frame are equipped with a full set of adjustment cylinders, which can easily adjust the drilling angle in all directions.
2.4 Equipped with high-power engine and advanced hydraulic system, it is stable, reliable and powerful.
2.5 The combination of down-the-hole impact and hydraulic rotation can greatly improve the hard rock drilling speed.
2.6 The dry dust collector (optional) can significantly reduce the dust concentration in the construction environment, protect the health of workers, and extend the life of equipment.
2.7 The drilling rig is simple and easy to learn to operate, so novices can quickly get started and reduce dependence on manual labor.
2.8 It adopts heavy-duty structural design, key parts are shock-proof and wear-resistant, with long service life and low failure rate.
