Working Principle of Borehole Drilling Rig
The electric drilling rig is the equipment that converts the electric energy and compressed air into mechanical energy to break rock. After electrifying, the drilling tool is driven by the torque produced by the cycloidal reducer through the intake seat. Compressed air is divided into two ways after going through an oil mist device and pneumatic valve: oneway enters into the cavity of promoting cylinder, which produces an axial force that drives the drilling tool to promote or elevate through the cylinder piston and guide rod; the other way enters into the impactor through the intake seat, so as to achieve impact drilling.

Advantages of Pneumatic Hydraulic DTH Drilling
1. Drill bits are made of alloy steel.
2. The impact energy loss doesn’t increase with the lengthening of the drill rod and can drill a large deep hole.
3. Used ordinary motor as the turning power, which is economical, efficient, and energy-saving.
4. The cycloidal pinwheel reducer has a large turning torque and high rock drilling efficiency.
5. Novel overload protection makes the rig run stably and reliably.
6. Three kinds of support structures: single top, double top, and support type, which can be adapted to any geological landform.
Applications of Pneumatic Hydraulic DTH Drilling Rig:
DTH Drilling Rig is widely used in large, medium, and small mines and large-diameter hole rock drilling operations in road construction, national defense, water conservancy, stone engineering, and slope treatment. It is also a good rock drilling equipment in the early stage of open pit mines. It is especially suitable for uneven terrain where other open-air DTH drilling rigs cannot operate normally; the machine has a compact structure, convenient operation, fast drilling speed, high efficiency, good disassembly of the whole machine, and extremely convenient transportation.
Daily maintenance of Pneumatic Hydraulic DTH Drilling
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.
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.
Packaging & Shipping
