DTH hammer basic structures:
DTH hammer components: Piston, internal cylinder, air distributor, check valve and drill bit accessories are installed in the external cylinder, the external cylinder has the top sub connected with its connection thread & wrench , there has a drive chuck threaded to the other end of cylinder. There is spline in the drive chuck which is mainly used to transfer feeding and rotational force to the drill bit. The stop ring controls the axial movement of the drill bit, and the check valve is used to prevent cutting and other foreign materials ingress into hammer in case of air supplying is stopped. During drilling, the drill bit is pushed into the hammer and pressed against the drive chuck, where the piston directly impacts the drill bit for crushing rock. Hammer start to clean the bottom by blowing up when bit lift from the hole.
It also has the following advantages:
1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of HD series DTH hammer designed according to newest rock drilling theory.
2. Smooth performance and long service life of HD series DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner structure of hammer.
4. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
5. Interchangeable with DTH bit and drill pipe
