Construction Equipment for High-Speed Rail Construction Rock Drill

      Rock drills work according to the principle of impact crushing. During operation, the piston undergoes high-frequency reciprocating motion, continuously impacting the drill tail. Under the action of impact force, the pointed wedge shaped drill bit crushes the rock and chisels it into a certain depth, forming a dent. After the piston returns, the drill bit rotates at a certain angle, and the piston moves forward. When it impacts the drill tail again, a new dent is formed. The fan-shaped rock block between two indentations is sheared by the horizontal force generated by the drill bit. The piston continuously impacts the tail of the drill bit and continuously inputs compressed air or pressure water from the center hole of the drill bit to discharge the rock slag outside the hole, forming a circular drilling hole of a certain depth.     Montabert  brand rock drills are currently the leading brand of rock drills, with mature technology, leading technology, and excellent quality. They are widely used in various fields such as mining, tunnel excavation, water conservancy engineering, and road construction. They have the characteristics of high efficiency and high return rate, and can effectively reduce engineering risks and labor intensity.
