30m Depth DTH Drilling Rig Machine Portable Mining Machinery
Description of DTH Drilling Rig
The essence of down-the-hole rock drilling is to make the impactor dive into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing the influence of the hole depth on the rock drilling efficiency.

Features of DTH Drilling Rig
1. Applicable type of down-the-hole impact with high rock drilling
efficiency.
2. With compressed air as the power source, the power is single,
safe, and reliable.
3. Simple structure, easy to use, short auxiliary time, and
lightweight.
4. The new angle mechanism makes the hole more convenient, adjusts
the scope larger, can reduce the requirements of the face;
5. With a dedicated drill pipe with a drill (drill pipe, sleeve,
eccentric drill, etc.), in the unstable formation with casing wall
openings, conventional ball teeth drill hole;
6. The rig can be directly connected to the hydraulic station, the
structure is simple; the hydraulic station frame is equipped with a
roller, which is easy to move and relocate. The engine is composed
of three parts: a host, a hydraulic station, and a console.
Application of Electric Borehole Drilling Rig
The Hydraulic DTH Rock Drilling Rig Machine is a submersible
electric rotary drilling rig, which is an ideal hole-forming
machine for drilling cast-in-place piles. It can also be used in
the construction of underground diaphragm walls and anti-seepage
curtains for shafts.
It is suitable for drilling in various formations such as silt,
clay, gravel layer, and weathered shale. It is widely used in the
basic construction of industrial and civil construction and other
projects.
The DTH drilling rig is widely applied to the road, national
defense, water conservancy, big stone projects and slope protection
projects, etc for small blasthole drilling. It is especially useful
for rugged and accident areas where another DTH drilling rig can
not work normally. With compact structure, easy operation, fast
drilling, high efficiency, easy to disassemble, and very convenient
for carrying
Daily maintenance of DTH Drilling Rig
1. Wipe the outer surface of the DTH drilling rig clean, and pay attention to the cleaning and good lubrication of the surfaces such as the slideway of the base of the DTH drilling rig and the vertical shaft.
2. Check whether all exposed bolts, nuts, safety pins, etc. are firm and reliable.
3. Add lubricating oil or grease according to lubrication requirements.
4. Check the integrity of the main components, if damaged, replace them in time, and do not work with injuries.
Packaging & Shipping of DTH Drilling Rig
In order to protect the portable DTH rock mine drilling rig and avoid damage during transport, our rock drilling rig adopts wood box package. And we also provide a customized package of our mine drill rig.
