The mini rock drilling machine is a small down-the-hole drilling machine, which can drill to a depth of 20~100m. It is small in size and easy to move and is suitable for places where large down-the-hole drilling machines cannot work. This small DTH drilling rig is a new type of high-efficiency rock drilling equipment, widely used in mining, water conservancy, construction, railways, roads, and other rock formations to drill large diameter deep holes. It is powered by compressed air and can work without electricity. The many advantages of the portable rock drilling machine make it a popular rock drilling equipment for customers.
Small DTH Drilling Rig Application
Small DTH drilling rig is widely used in small and medium-sized mines, hydropower, transportation and other earthwork excavation projects, and coal mine roadway support projects. A pneumatic borehole drilling rig is a machine designed according to the engineering characteristics of the road, railway, water conservancy, hydropower, mine construction, and so on. In the early stages of these projects, the roads were inconvenient and large equipment could not be used. The portable rock drilling machine was easy to move and use, making it very popular among customers.

Composition of Mini Rock Drilling Machine
The above are the components of the mini rock drilling machine. YGQ100 small down-the-hole drilling rig mainly includes a carriage, outrigger, console, cylinder, power head, and so on. The reducer and the air motor form the structure to realize the rotation of the drilling tool. The pushing cylinder pushes the compressed air out for rock drilling.
Small Hammer DTH Drilling Rig Working Principle
The small blasting rock drilling rig is powered by compressed air and converts compressed air into mechanical force to break rocks. The impactor and drill bit is installed on the small down-the-hole drilling rig. During the working process, the piston of the impactor continuously impacts the tail of the drill bit, and the alloy teeth on the drill bit continuously impact the rock. The reducer generates rotational torque to rotate the drilling tool, and the power generated by the thruster cylinder is sent to the drilling tool for drilling.
Portable DTH Drilling Rig VS Rock Splitter
The down-the-hole drilling rig is a kind of equipment that is often used to drill into rocks. In addition, there is a hydraulic rock splitter. The down-the-hole drilling rig is an impact rotary structure, the front end is directly connected to the drill bit, and the rear end is connected to the drill pipe. When drilling rock, the impactor submerges into the hole, and the piston in the impactor reciprocates through the pneumatic device to strike the drill bit. Therefore, the drill bit produces an impact force on the rock to drill the hole.
Hydraulic rock splitters use hydrodynamic methods to split rocks. It has a great advantage in breaking rocks where construction and earthworks cannot be excavated. It is the best equipment for splitting rock, concrete, metal ore, and other hard materials.
Advantages of Mini Rock Drilling Machine
- Small size, lightweight, convenient, and flexible construction.
- Suitable for places where medium and large drilling rigs cannot work.
- High drilling efficiency, can drill 20-30m per hour.
- The high-performance reducer is used as the rotary power, and the cylinder is used to propel the power, which has high mechanical efficiency, low cost, and stable performance.
- Widely used. It is suitable for drilling rock anchor rods, blast holes, grouting holes, etc. in urban buildings, railways, and highways.
- The rolling pallet is adopted, and the track is not easy to wear.
- With anti-jamming protection, when the drill is stuck, the belt is not easy to be burned, and the reducer is not easy to be damaged.
