120 type down the hole drilling rig slope support small and lightweight bracket drilling fast

Machine Introduce :
Down-the-hole drilling rig is an impact rotary drilling rig. Its internal structure is different from that of a general rock drill. Its gas distribution and piston reciprocating mechanism are independent, that is, an impactor. The front end is directly connected to the drill bit, and the rear end is connected to the drill rod. When rock drilling, the impactor dives into the hole, and through the gas distribution device (valve), the piston (hammer) in the impactor reciprocates against the drill tail, so that the drill bit generates a vortex force on the rock at the bottom of the hole

Machine Feature :
Small size and light weight, suitable for places where large and medium-sized rigs cannot perform operations, convenient and flexible. Down-the-hole drilling rig adopts electric energy as power, with low noise and strong power. The drilling speed is 3-8 times that of ordinary rock drills, the rock hardness reaches 9 and the drilling depth per hour is 8-16 meters
