    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. according to China's mining conditions, to absorb the advanced technology of domestic and foreign impactor and design and manufacture of the latest products.


    2. reasonable selection of materials, advanced manufacturing technology, quality assurance perfect.


    3. has higher drilling speed.


    4. can provide hardening treatment in order to prolong the service life and reduce the cost of use.


    5. single impact power is large, and the power consumption of broken rock is low.


    6. piston and bit weight to have the best momentum transfer.


    7. the modern theory is adopted in the structural design, which makes the stress wave duration longer, the stress amplitude is lower, and the piston life is long.


    Applications


    It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.
