Definitions

  • the present invention relates to a hydraulic breaker equipped with a direct-coupled lubricant automatic supply block.
  • Hydraulic breakers are equipment that is mounted on construction equipment such as excavators and lifts or lowers the piston, which is a lifting member, by a power source such as hydraulic pressure and uses the striking force generated through this to crush objects such as rock and concrete.
  • the hydraulic breaker injects lubricant into the front head surrounding the chisel to prevent wear due to friction of the chisel that is struck as the piston rises and falls.
  • Lubricant can be injected manually by the operator. However, in this case, there is a problem that the efficiency of hydraulic breaker work is reduced because the operator must periodically inject lubricant. In addition, if the timing of lubricating oil injection is missed, severe wear may occur inside the front head, shortening the lifespan of the piston and chisel.
  • Hydraulic breakers are equipped with an automatic lubrication device provided as a separate part that is exposed to the outside.
