Portable Electric Borehole Drilling Rig for Quarry
Description of Electric Borehole 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.

Working Description of Electric Borehole Drilling Rig for Quarry
The DTH rock drilling rig 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 impact of the hole depth on the rock drilling efficiency.
Features of Electric Borehole Drilling Rig for Quarry
1. Drilling machine full hydraulic drive, easy operation and
flexible, easy to shift, good mobility, saving time and effort;
2. Drill rotator with dual hydraulic motor drive, the output
torque, greatly improving the drilling rig rigidity;
3. The new angle mechanism makes the hole more convenient, adjusts
the scope larger, can reduce the requirements of the face;
4. 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;
5. 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.
DTH drilling rig is mainly used for drilling blasting holes in
open-pit mines, and can also be used for open-pit drilling
operations in construction, water conservancy, electric power
engineering, highway, railway, and military engineering. It is the
main perforating equipment for small and medium-sized open pit
mines.
Daily maintenance of Electric Borehole 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. Remove the dirt and mud on the tooth surface of the chuck and slip.
5. Clean up the oil and mud on the inner surface of the brake.
6. Clean the filter in the oil tank and replace the deteriorated or dirty hydraulic oil.
7. Check the integrity of the main components, if damaged, replace them in time, and do not work with injuries.
