Abstract
Provided is a stepless variable auto stroke hydraulic breaker system capable of reducing impact energy reflected in the event of an idle blow by detecting a frequency of vibrations generated when a chisel breaks objects such as bedrocks using a vibration sensor, operating according to a short stroke if the frequency of vibrations does not exceed a preset frequency, and automatically switching the short stroke into a long stroke if the frequency of vibrations exceeds the preset frequency. The breaker system includes a vibration sensor configured to detect vibrations generated when a chisel breaks rocks, a transmitter provided with the vibration sensor and configured to transmit signals generated from the vibration sensor, a receiver configured to receive the signals transmitted from the transmitter, and a stepless variable auto stroke hydraulic breaker controlled by a reception micro controller unit (MCU) of the receiver.
