KQZ Series Air-electric Down-the-hole Drilling Rig
- Introduction toKQZ Series Air-electric Down-the-hole Drilling Rig
The KQZ series air-electric down-the-hole drilling rig is a highly efficient rock drilling equipment. It uses compressed air to drive the impactor to generate high-frequency impact force on the drill bit. At the same time, the electric motor drives the drill bit to rotate at high speed to achieve efficient rock crushing. It is an efficient and reliable choice for hard rock deep hole operations. It is mainly used in open-pit mine blasting holes, large-scale stone projects, water conservancy and hydropower construction and other fields.
- Features of KQZ Series Air-electric Down-the-hole Drilling Rig
2.1 High-efficiency drilling: The impact drilling method is adopted, and the impact energy directly acts on the drill bit at the bottom of the hole, with small energy transfer loss, which greatly improves the drilling efficiency.
2.2 Good drilling quality: the drilled hole is straighter, the hole wall is smoother, and the drilling accuracy is higher.
2.3 Strong adaptability: It can adapt to a wide range of strata from soft rock to extremely hard rock.
2.4 Simple operation: The drilling rig is easy to operate and novices can quickly get started, reducing manual dependence.
2.5 Durable: Made of high-strength materials, it has good wear resistance and impact resistance, can operate stably for a long time, and reduces the cost of repairing and replacing equipment.
