Down the hole drilling machine is known as a portable drilling rig or tripod drilling rig. There is a variety of models for DTH drilling machines for sale in YG Machinery. The equipment mainly includes three types, gas-electric linkage DTH drilling equipment, electric down-the-hole drilling rigs, and fully pneumatic down-the-hole drilling rigs. The first one needs an air compressor and electricity, while the last one only requires an air compressor. If you are interested in the equipment, welcome to get in touch with us freely to learn more information.

Features of the Down the Hole Drilling Machine
- It has a compact structure, simple operation, fast chisel speed, high and efficiency.
- The DTH boring machine is a good disassembly of the whole machine and extremely convenient transportation.
- There are twist drill pipes for soil drilling and special round steel drill pipes for rock drilling.
- Small volume, lightweight, powerful, portable, high-quality material, durable, precision machining, and humanized design.
Working Principle of the Down the Hole Drilling Machine
The DTH drilling rig is a composite power model, and its power is partially combined with compressed air. The power to rotate the drilling tools of the drilling rig comes from the electric motor, and the impact force of the impactor comes from the compressed air. The motor studio converts electrical energy into rotational torque and transmits it to the reducer, which rotates the drill rod connected to the output shaft of the reducer. The alloy teeth at the front end of the impactor continuously impact the broken rock, and the broken rock is blown to the ground by the air pressure of the car in the drill hole. The axial force generated by the propelling cylinder is sent to the drilling tool for drilling.
Down the Hole Drilling Rig Uses
Small down the hole drilling machines are suitable for large-diameter blast hole rock drilling operations in small and medium-sized mines, road construction, national defense water conservancy, and stonework projects. They are also indispensable rock drilling equipment for the early mining conditions of open-pit mines. They are especially suitable for drilling operations that cannot be achieved in rough terrain by other drilling rigs. It is widely used in slope support, quarries, water conservancy projects, anchor bolts and cables, highway and railway construction, etc.
Brief Introduction of the SKD70 DTH Rig Machine
The SKD70 down-the-hole drilling machine is powered by a motor and compressed air. The power to rotate the drilling tools of the drilling rig comes from the motor, and the impact force of the impactor comes from the compressed air. When the motor works, it converts electrical energy into rotational torque and transmits it to the reducer, which rotates the drill rod connected to the output shaft of the reducer. The alloy drill bit at the front of the impactor constantly impacts the crushing and grinding rock, and the broken rock is blown to the ground by the air pressure discharged from the drill hole. The SKD70 DTH drilling rig is characterized by its portability and economy. It is the nemesis of inconvenient roads and steep hillsides at construction sites. Mainly used in slope support, road and railway excavation construction, etc.
Advantages of the DTH Drilling Equipment
- High mechanical efficiency: the motor is used as the rotating power through a high-performance reducer
- Easy to move: the weight of the whole machine is less than 500kg, and it is convenient to put on the shelf
- Anti-jamming protection: when the drilling tool is stuck, the motor is not easily burned, and the reducer is not easily damaged
- Rolling carriage: using a rolling carriage, the track is not easy to wear
