Applicable range
ZQJ-300/6 pneumatic bracket drilling machine is widely used in coal mine projects such as water detection hole drilling, water injection hole drilling, gas drainage hole drilling etc.
Structure feature
The ZQJ-300/6 is a power head drill.It mainly adopts high efficiency spiral rod and carbide drill bit for rotary drilling. The rotating head has forward and reverse function, easy to feed and draw back the drilling rods. The feeding unit utilizes independent motor, it is more powerful and durable. The feeding speed can be easily adjustable by controlling air volume. It can be controlled remotely by separate platform. Unique dual silencer minimize noise, main frame, prop leg and operation platform are freely plugged and come into using, easy to move.
