The Working Principle of Rock Drilling Equipment
The rock drilling equipment works according to the principle of impact crushing. When it works, the piston makes high-frequency reciprocating motion and continuously impacts the bit tail. Under the action of the impact force, the wedge-shaped drill head crushes the rock and chisels it into a certain depth to form a dent. After the piston retreats, the brazing rod turns to a certain angle, the piston moves forward, and a new dent is formed when the hammer tail is impacted again. The fan-shaped rock between the two dimples is shredded by the horizontal component generated by the bit. The piston impacts the shank continuously and inputs compressed air or pressurized water from the center hole of the drill to discharge the slag out of the hole, which forms a circular drilling hole of a certain depth.
How To Operate The Rock Drilling Machine
1. Before putting the equipment into use, check the integrity and rotation of each component, add necessary lubricating oil. Check whether the airway, the waterway is unlocked and whether the joint is firm.
2. Check if there is a live stone, pine stone near the working face and make necessary treatment.
