Product Introduction

Product Introduction

Pneumatic Chain Drive Roof bolter Anchor Drill is widely used in tunnel side rock with rock hardness ≤ f10, especially for anchor support operation of coal tunnel side rock. It can drill side anchor holes and anchor cable holes, and can also mix and install resin drug roll anchors and anchor cables. No other equipment is needed to achieve one-time installation and tightening of anchor nuts to meet the requirements of initial anchor preload.

Working Principle

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

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 the water valve to open, and the flushing water will enter the drill pipe through the filter, water valve, water jacket, and spindle inner hole to flush the borehole.

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