Benefits of using down-the-hole drilling rigs
Product Overview The down-the-hole drilling rig is an impact rotary drill. Its internal structure is different from that of general rock drills. Its gas distribution and piston reciprocating mechanisms are independent, that is, the impactor. . The front end is directly connected to the drill bit and the rear end is connected to the drill pipe. When rock drilling, the impactor dives into the hole and uses the gas distribution device (valve) to make the piston (hammer body) in the impactor reciprocate and strike the drill tail, causing the drill bit to generate a spinning force on the rock at the bottom of the hole.
Product Features Small size It is light in weight and suitable for places where large and medium-sized drilling rigs cannot operate. It is convenient and flexible. The down-the-hole drilling rig uses electric energy for power, with low noise and strong power. The drilling speed is twice that of ordinary rock drills. The rock hardness reaches 30 meters per hour.
