KQZD-420S Oil-Electric Hybrid Down-the-Hole Drill Rig

TheKQZD-420S Oil-Electric Hybrid Down-the-Hole Drill Rig is a type of efficient and flexible open-pit crawler-type rock drilling equipment. It transmits impact energy to the drill bit through an impactor; while the drill bit impacts the rock at high frequency, it rotates at high speed, and compressed air discharges the drilled rock cuttings out of the hole, realizing the synchronous operation of "impact-rotation-slag discharge". The down-the-hole drill rig has excellent mobility and off-road capability, adapting to all-terrain operations and enabling fast and flexible transition in complex terrains. It is mainly used in fields such as open-pit mine blast holes, large-scale rock engineering, and water conservancy and hydropower construction. Jujang down-the-hole drill rig is an efficient and reliable choice for hard rock deep-hole operations.

Commodity name: KQZD-420S Oil-Electric Hybrid Down-the-Hole Drill Rig

1.Introduction toKQZD-420S Oil-Electric Hybrid Down-the-Hole Drill Rig

2.Features ofKQZD-420S Oil-Electric Hybrid Down-the-Hole Drill Rig

2.1.Adopts a steel crawler chassis, featuring excellent off-road performance.

2.2.Some models are equipped with pitch cylinders on the crawler frame, which can freely adjust the center of gravity of the machine body, ensuring stability and safety during drilling operations on uneven terrain.

2.3.The drill arm and drill frame are equipped with a complete set of adjustment cylinders, enabling easy all-round adjustment of the drilling angle.

Equipped with a high-power engine and an advanced hydraulic system, it is stable, reliable and powerful.

2.4.The combination of down-the-hole impact and hydraulic rotation greatly improves the hard rock drilling speed. The dry dust collector (optional) can significantly reduce the dust concentration in the construction environment, protect the health of workers and extend the service life of the equipment.

2.5.The drill rig is easy to operate and learn, allowing new operators to get started quickly and reducing reliance on skilled labor.

2.6.Adopts a heavy-duty structural design; key parts are shock-resistant and wear-resistant, ensuring a long service life and low failure rate.

2.7.The KQZD-420S drill rig has been fully upgraded and optimized based on the original 420B model, maximizing the functions of the drill rig. It is upgraded to a dual-power design, a diesel-electric dual-purpose model that can switch power at any time to meet the different construction requirements of customers.
