The down-the-hole drill rig is indeed an impact rotary drill rig that operates differently from a conventional rock drill. Its internal structure features an independent gas distribution and piston reciprocating mechanism, known as the impactor. The impactor is directly connected to the drill bit at the front end and connected to the drill rod at the rear end.
During the rock drilling process, the impactor moves into the hole. Through the gas distribution device (valve), the piston (hammer body) inside the impactor reciprocates, delivering impacts to the bit shank. This action generates a rotational force on the drill bit, enabling it to effectively penetrate and impact the rock at the bottom of the hole. This impact rotary mechanism helps to enhance the drilling efficiency and overall performance of the down-the-hole drill rig.

DXL-70 YQ Portable Type DTH Drilling Rig
Compact Portable DTH Drilling Solution For Rock Excavation And Mining

The DXL-70 YQ Portable Type DTH Drilling Rig is a professional small-scale rock drilling machine developed for customers who need efficient drilling performance combined with excellent portability. Designed with advanced Down-The-Hole (DTH) drilling technology, this portable drilling rig provides reliable rock penetration, accurate hole formation, and convenient operation in various jobsite conditions.

Unlike large crawler-mounted drilling rigs, the DXL-70 YQ focuses on flexibility and mobility. Its lightweight structure allows easy transportation and quick installation, making it especially suitable for small mines, quarries, construction sites, and areas where large drilling equipment cannot easily access.

The machine uses compressed air-powered DTH impact technology. The impactor works close to the drill bit, transferring impact energy directly into the rock formation. This design reduces energy loss through the drill rod and improves drilling efficiency, especially in hard rock conditions.

With its compact size, reliable performance, and economical operation, the DXL-70 YQ Portable Type DTH Drilling Rig is an ideal choice for contractors, mining operators, and engineering companies requiring a practical rock drilling solution.
