HQD70 Electric Down-the-Hole Drill: Efficient and Versatile Solution for Various Drilling Projects

Hand hold pneumatic rock drill(Jack hammer) is a carefully developed new generation of portable machine with novel structure,remarkable performance.

The weight of the hand-held rock drill is relatively light, generally below 25kg, and it is operated by hand when working. A variety of small diameter and shallow holes can be drilled, generally only down holes and near-horizontal holes. Because it relies on manual operation, high labor intensity, small impact energy and torque, and slow rock drilling speed, it is rarely used in underground mines now. Rock drills belonging to this category include models such as Y3 and Y26.

First you need to consider where your rock drill is going to be used and how big of a hole are you going to drill? How soft is the rock? Is the punching direction down, horizontal or up?

1. The larger the aperture, the larger the rock drill model.
2. The higher the hardness, the higher the impact energy and power of the rock drill.
3. The drilling direction determines the support method you choose for the rock drill. There are hand-held and outriggers.

The air-leg rock drill is installed on the air leg for operation, and the air leg can play the role of support and propulsion, which reduces the labor intensity of the operator, and the rock drilling efficiency is higher than the former. The drilling depth is 2-5m and the diameter is 34- 42mm horizontal or with a certain inclination of the blasthole, which is widely used in mines. Such as YT23, YT24, YT28, YTP30 and other models are such rock drills.

The HQD70 Electric Down-the-Hole Drill is a newly designed, highly efficient and widely applicable rock drilling equipment. It serves well in small and medium-sized mines, as well as in transportation, national defense, water conservancy, and stonework projects. Especially suitable for uneven and rugged terrains where other drill rigs can’t operate normally. With a simple structure, easy operation, low cost, and energy-saving features, it can drill both vertical and horizontal blast holes. Its low center of gravity and good disassembling property make relocation and transportation extremely convenient. The drill has a low air consumption of the impactor, requiring a small displacement air compressor, which is economical. The rotary reducer has a large torque and shows good reliability under strong vibration and high load. The electrical system has overload and phase loss protection functions, ensuring stable and reliable operation. The propulsion system is equipped with a pressure reducing valve to adjust the propulsion force according to different rock conditions for the best drilling effect.
