Rock drilling tools/Down-The-Hole HAMMER
Feartures:
DTH ,the “down-the-hole” was originally developed to drill large-diameter holes downwards in surface-drilling applications,of which the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards.
In DTH drilling, the percussion mechanism – the hammer – is located directly behind the drill bit. The drill pipes transmit the necessary feed force and rotation to hammer and bit plus compressed air or fluids for the hammer and flushing of cuttings. The drill pipes are added to the drill string successively behind the hammer as the hole gets deeper. The piston strikes the impact surface of the bit directly, while the hammer casing gives straight and stable guidance of the drill bit. This means that the impact energy does not have to pass through any joints at all. The impact energy therefore is not lost in joints allowing for much deeper percussion drilling.
Because of the efficiency of powerful drilling capacity,DTH hammer becomes an advanced rocking drilling tools for construction,mining ,etc.DTH hammers and bits are designed to work together in perfect unison.
SUG HAMMER:
The series SUG hammers developed and manufactured by SUG Co.,Ltd is one of the most advanced valveless high air press DTH hammer in China.It has following advantages:
Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to inner structure of SUG series DTH hammer designed according to newest rock drilling theory. Smooth performance and long service life of SUG series DTH hammer due to high quality alloy steel materials and advanced processing technology adapted. Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer. Interchangeable with DTH bit and dill pipe manufactured by Atlas copco and Ingersoll-rand.Low pressure and high pressure hammers are available in SUG.
