Abstract (en)
[origin: WO9611306A1] The present invention relates to a vibrating device for an operating machine for a hydraulic shovel for efficiently performing vibrating operations such as digging and roll-compacting work. To this end, the vibrating device comprises a rotary vibrating valve (15) for continuously switching pressure oil from a hydraulic source (10) for discharging and a vibrating mode switching valve (17) having two positions, a position where switched discharge oil is continuously discharged in one direction and another position where said oil is alternately switched for discharging, wherein discharge oil from said vibrating mode switching valve (17) is supplied to either actuators (5, 7, 9) for said operating machine or vibrating actuator (30) so as to vibrate said operating machine (1a).
