Abstract

The present invention relates to a hydraulic breaker with an automatic grease supply, more specifically to a hydraulic breaker with an integrated automatic grease supply device which automatically supplies a proper amount of grease only when the hydraulic breaker is in operation so that grease is always supplied during operation, unlike manual injection of grease, and therefore the abrasion of a chisel is prevented and work efficiency is improved as a worker does not need to stop working to inject grease. The hydraulic breaker of the present invention to achieve the mentioned object includes an automatic grease supply device integrally formed on top of the hydraulic breaker. The automatic grease supply device comprises a grease container formed on top of the hydraulic breaker, an injection path for injecting grease into the grease container, and a supply path for supplying grease from the grease container.
