Down the hole drill professional production of down the hole drill in the promotion of down the hole drill

  Product introduction the down the hole drill uses the impactor and drill bit that dive into the bottom of the hole to impact and break the rock, zmjt056 so it is called down the hole drill
It is widely used in metal mines, hydropower, transportation, building materials, harbors and national defense projects
Down the hole drill can drill holes in rocks above medium hard (F & Ge; 8)
The price of drilling rig is relatively cheap, which is especially suitable for small and medium-sized open-pit mines

Product classification of down the hole drill
1
According to different places of use, it can be divided into underground DTH drilling rig and open-air DTH drilling rig
For example, the downhole down the hole drill has K7 & mdash; 80、KQJ— 100 type, open-air down the hole drill with KQ & mdash; 100、KQ— 150、KQ— 200、KQ— Type 250

2
According to different hole diameters, it is divided into light down the hole drill (the hole diameter is 80 ~ 100mm, and the machine weight is hundreds of kilograms to 2 ~ 3T), medium-sized down the hole drill (the hole diameter is 150mm, and the machine weight is 10 ~ 15t), heavy-duty down the hole drill (the hole diameter is 200mm, and the machine weight is 25 ~ 35t), and extra heavy down the hole drill (the hole diameter is 250mm, and the machine weight is 40 ~ 45t)

Working principle of down the hole drill
The working principle of down the hole drill is the same as that of other rock drills
It has rock drilling and hole forming processes such as impact, rotation, mucking and propulsion
It belongs to impact rotary drilling
The difference is that the impactor of the down-hole drill is installed at the front end of the drill pipe, sneaks into the hole bottom and advances continuously with the extension of the drilling hole

Characteristics of down the hole drill
① The impact energy loss does not increase with the lengthening of the drill rod, and deep holes with large hole diameter can be drilled;
② The noise of working face is greatly reduced;
③ The drilling speed is fast, the degree of mechanization is high, and the auxiliary operation time is less, which improves the operation rate of the drilling rig;
④ Flexible;
⑤ High drilling quality;
⑥ It can drill medium hard or medium hard rock (F & Ge; 8)
