Description of Portable DTH Drilling Rigs
Down-the-hole Drilling Rig, usually called DTH Drilling Rig by most professionals. It is basically a portable machine on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water, or drilling mud).
YG DTH drilling rig machine is an advanced drilling equipment that integrates the downhole drilling system and the screw air compression system. It is powered by a high-quality diesel engine and is compact. It is convenient, flexible, and enjoys high popularity.

Main Application of Pneumatic DTH Drilling Rig
Pneumatic DTH Drilling Rig is often used in the mining industry (blast hole drilling), on construction sites, drilling water wells, and in the oil and gas industry.
The down-the-hole drilling rig machine is mainly suitable for large-diameter blast hole rock drilling in small and medium-sized mines, road construction, water conservancy, and stonework projects, as well as drilling anchor holes in slope support, tunnel support, and foundation pit support. The main drilling object is the rock formation.
Unique Benefits of YG Portable DTH Drilling Rigs
1. Compact Structure and Easy Operation
YG DTH Drilling Machine is small and lightweight. It is suitable for places where large and medium-sized rigs cannot operate. It is convenient, flexible, and easy to operate.
2. High Efficiency and Stable Performance
YG down-the-hole drilling machine uses excellent motors, with high working efficiency and stable performance.
3. Low Noise and High-Speed Drilling
YG DTH Drilling machine uses electrical energy turned into power, with small noise and strong power. The drilling speed is 3-8 times that of the average rock drilling machine, the rock hardness reaches 9, and the drilling depth of each hour is 8-16 meters.
4. Easy to Install and Disassemble
The overall volume of the down-the-hole drilling rig is relatively small, and it is very easy to install and disassemble, which is conducive to work efficiency.
Operating Principle of Portable DTH Drilling Rigs
The working principle of the down-the-hole drilling rig is: compressed air drives the piston in the impactor, hitting the drill bit for rock drilling. When the motor is working, the electrical energy is converted into a rotating torque to the reducer to make the drill rod rotate the drill rod connected to the output shaft of the reducer. The excreted air pressure blows to the ground.
