The present invention relates to a screen bucket, which includes: an outer bucket portion having an empty inner bucket part; an inner bucket portion assembled inside the outer bucket portion to have a screen disposed at the empty inner bucket part; vibration-damping rubber connecting the outer bucket portion with the inner bucket portion through both sides of the upper and lower ends; a vibration drum fixed on an inner linking plate defining the upper end portion of the inner bucket portion; and a hydraulic motor fixed at the side of the vibration drum to receive hydraulic pressure from an excavator and generate vibration by rotating an eccentric shaft fixed to a rotating shaft at a high speed in the vibration drum. According to the screen bucket of the present invention, work efficiency may be raised and operation and manipulation may be made more convenient since vibration-based screening is carried out with the screen and the bucket being separated from each other; product lifespan may be extended; and accidents may be prevented since no burden is imposed on the excavator joint. |
