New dust-free pneumatic down the hole drilling machine, engineering drilling machine, tunnel rock drilling machinery

　　The open-pit/underground down the hole drilling rig is a new type of rock drilling equipment that our company has independently planned and is highly applicable. It can perform rock drilling processes for both open-pit and underground construction through the drilling frame. Large diameter hole rock drilling is widely used in small and medium-sized mines, as well as in road construction, national defense, water conservancy, and rock engineering. It is also an essential rock drilling equipment in the early stage of open-pit mining, especially in areas where other drilling rigs cannot operate normally.

　　The QKZ-70D pneumatic electric down the hole drilling rig is an impact rotary drilling rig. Its internal structure is different from that of a general rock drill, and its gas distribution and piston reciprocating mechanism are independent, namely the impactor. The front end is directly connected to the drill bit, and the back end is connected to the drill rod. During rock drilling, the impactor penetrates into the manhole and, through a gas distribution device (valve), causes the piston (hammer) inside the impactor to reciprocate and strike the tail of the drill rod, creating a rotational force on the rock at the bottom of the hole.
