The small down-the-hole drilling rig is a new type of energy-saving and high-efficiency rock drilling equipment designed by our company. Rock drilling equipment is essential for mining, especially suitable for uneven and rugged terrain where other drilling rigs cannot work normally. The Small DTH Drilling Rig has the advantages of a compact structure, convenient operation, fast cutting speed, high efficiency, good detachability of the whole machine, and extremely convenient transportation.

Small DTH Drilling Rig is also called Small Outrigger Type Down-the-hole Drilling Rig, or portable DTH Drilling Rig. Small Down-the-hole drilling rigs are divided into gas-electric down-the-hole drilling rigs (air compressor + electricity), also called electric down-the-hole drilling rigs. It is a kind of compound power model, powered by a motor and compressed air. And fully pneumatic down-the-hole drilling rigs (only air compressors are required). It is a method that uses compressed air as the power to convert compressed air into mechanical force to break rocks.
Small down-the-hole drilling rigs are 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.、
The small down-the-hole drill is small in size and light in weight. It is suitable for places where large and medium-sized drilling rigs cannot work, and is convenient and flexible. The down-the-hole drilling rig is powered by electric energy, with low noise and strong power. The drilling speed is 3-8 times that of ordinary rock drills, the rock hardness reaches 9, and the drilling depth per hour is 8-16 meters.

What You Need To Know About Small DTH Drilling Rigs
How to choose accessories for clay and wet soil?
Replace the polished rod, impactor, and alloy drill bits in the standard configuration with twist drill rods and three-lobe drill bits.
How to choose accessories for hard soil and rock?
Directly use an impactor and alloy drill bit, and the effect is better and faster.
Do you need an air compressor for soil digging?
Because it is cylinder propulsion, all down-the-hole drilling rigs need to be equipped with an air compressor.
What should I do if the hole collapses? (Rock or soil layers cannot form holes)
Casing (heel pipe) is required for the casing to be matched with the polished rod, impactor, eccentric drill bit, casing, pipe shoe, extubation machine, and free forceps.
What if the rock is too hard?
Hit with high wind pressure impactor and high wind pressure alloy drill bit. Down-the-hole drilling rigs cannot be drilled, and anchor drilling rigs must be used.
How to buy an air duct?
The drilling rig has its own air duct connecting the console and the power head. It is also necessary for the customer to purchase the air duct connected to the air compressor by himself. Generally, 38 single-layer steel wires and 20-meter air ducts are used, which can be purchased together with the drilling rig.
What is the minimum hole size for the drill?
The minimum specification of the alloy drill bit is 55, 65, and 76mm. So the minimum hole diameter is 55mm.
Can the down-the-hole drilling machine drill holes above 130mm?
Yes, generally you need to order a large drill bit, but you can’t drill deep. Because the hole diameter becomes larger, it is difficult to remove the broken slag at the bottom, so a larger air compressor is needed.
