A portable DTH boring machine is one of the excellent drilling equipment. The lightweight down-the-hole drill is a kind of drilling equipment driven by a pneumatic motor or electric motor and directly pushed by the cylinder. It has reliable performance, single power, small size, lightweight and high efficiency. It is an ideal drilling equipment for small mines and earthwork excavation projects. This machine is also an indispensable auxiliary drilling equipment for large and medium-sized mines and engineering construction. YG provides various types of small DTH drills, such as gas-electric linkage down-the-hole drills, electric down-the-hole drills, and full-pneumatic down-the-hole drills. You are welcome to come to consult and obtain, we provide you with competitive prices.

Application of Portable Dth Boring Machine
A portable DTH boring machine is suitable for large-diameter blast hole drilling in small. And medium-sized mines and road construction, national defense water conservancy, and stone engineering. It is also an indispensable rock drilling equipment for the early mining conditions of open-pit mines, especially for rugged terrain where other drilling vehicles cannot work normally. A portable DTH drilling rig is widely used in slope support, quarries, water conservancy projects, anchor bolts and cables, highway and railway construction, etc.
Components of Small Dth Drilling Machine
The light DTH drill is mainly composed of a slide rod extension, slide, starter motor rotary power head, cylinder, impactor, drill bit, leg, hose, operating table, and other parts.
Working Principle of Pneumatic Dth Drill Rig
The core of a portable DTH boring machine is its impactor. It directly dives into the bottom of the hole and connects to the drill bit. When working, the piston in the impactor reciprocates through the control of the gas distribution device. And it directly impacts the drill bit, so that the drill bit produces a strong impact force on the rock at the bottom of the hole, thereby achieving rock crushing. While impacting and crushing, the drill bit also realizes continuous rotation through the rotary mechanism. This rotary motion helps to discharge the broken rock debris from the bottom of the hole. And it provides a new contact surface for the next impact crushing.
4 Advantages of Smart Dth Rig Machine
- High efficiency: Since the impactor directly dives into the bottom of the hole to operate, the loss of impact energy is reduced. So the light down-the-hole drill rig has a higher drilling efficiency.
- Stable operation: The structural design is reasonable, and the operation is stable and reliable. And it can adapt to various complex geological conditions.
- Low cost: Compared with large rock drilling equipment, the purchase cost, and maintenance costs. Use cost of light down-the-hole drill rigs is lower, which is suitable for small and medium-sized projects.
- Wide adaptability: A portable DTH boring machine is widely used in rock drilling projects in geological exploration, construction engineering, mining engineering, open-pit mining, road construction, hydropower stations, and other fields.
