PURPOSE: A screen bucket is provided to perform screening through vibration in a state that a screen and a bucket are respectively fixed. CONSTITUTION: Dustproof rubber connects an outer bucket to an inner bucket. A vibration drum(230) is fixed onto the inner connecting plate(260) of the inner bucket. A hydraulic motor(250) is fixed to one side of the vibration drum. The hydraulic motor receives the fluid pressure of an excavator. The hydraulic motor rotates the eccentric shaft of a rotary shaft at a high speed in the vibration drum. The hydraulic motor generates vibration.
