Product Introduction

Product Introduction

Pneumatic Roof bolters are widely used in tunnels with rock hardness ≤ f12, especially for bolt support operations in coal tunnels. They can drill roof bolt holes and anchor cable holes, and can also mix and install resin-coated anchor bolts and anchor cables. No other equipment is required to achieve one-time installation and tightening of anchor nuts to meet the requirements of initial anchor preload.

Working Principle

Compressed air passes through the filter, oiler, and filter screen and enters the valve block of the operating arm component.

Press the trigger by hand to open the motor control valve, and the compressed air drives the gear-type air motor. The output gear is reduced in two stages to drive the main shaft to rotate clockwise.

Turn to open the air leg control valve, and the compressed air enters the upper chamber of the air leg through the quick exhaust valve, and the air leg extends. When the air leg control valve is closed, the remaining air in the upper chamber of the air leg is vented from the quick exhaust valve, and the air leg falls back by the gravity of the drilling rig.

Turn to open the water valve, and the flushing water enters the drill pipe through the filter, water valve, water jacket, and the inner hole of the main shaft to flush the borehole.

Manually adjust the opening amount of each valve to adjust the speed, thrust or water volume.
