Advantage
The contemporary new rock drilling theory is used to design the internal
structural dimensionsof the impactor, so that the impactor can obtain ideal energy transfer,
with large single impact power and fast rock drilling speed.
Working principle of down-the-hole drilling rig impactor:
The rotary motion of the impactor is provided by the rotary head, and the shaft thrust is provided by the propeller and transmitted to the impactor through the drill rod.
The card sleeve is mainly used to transmit propulsion force and rotational motion to the drill bit. The snap ring controls the axial movement of the drill bit, and the check valve is used to prevent rock ballast and other debris from entering the impactor when the supply of compressed air is stopped.
