1. The contemporary new rock drilling theory is used to design the internal structural dimensionsof the impactor, so that the impactor can achieve ideal energy transfer, large single impact power, and fast rock drilling speed.
2. Unique taper diameter reduction design. If gravel and soil are stuck during drilling, the taper diameter reduction can reduce the lifting resistance when the drill rig is lifted up, greatly reducing the failure of the impactor to be lifted out.
3. In order to prevent dust pollution during perforation rock drilling operations,the main components of the product also adopt a special new computer-programmed heat treatment process to facilitate adding a small amount of high-pressure water to the compressed air for wet rock drilling to protect the operator's health, healthy.
Working principle of down-the-hole drilling rig impactor:
The compressed gas enters the impactor through the drill pipe, and is then discharged from the drill bit. The discharged exhaust gas is used to discharge ballast. 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.
During the drilling process, the drill bit is pushed into the impactor and pressed against the card sleeve. At this time, the piston directly impacts the drill bit to drill the rock. When the drill bit is lifted away from the bottom of the hole, it starts to blow hard.
