Description


Down the hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powderto a down-the-hole bit to crush rocks.

1. Based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.


2. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.


3. The collection tube adopts an integrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.


4. Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer
can drill holes of different sizes ensuring that the sample is not contaminated.


5. In difficult conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.


Applications



Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole, mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
