    Abstract: Disclosed is an apparatus for screening material at the end of an excavator arm comprising a blade having a bottom edge, a top edge and a connector therebetween for securing to a distal end of the arm of a earth moving equipment. The bucket has a bottom screen having front and rear edges being rotatable about the top edge of the blade section. The bottom screen is positionable so as to extend angled away from the bottom edge of the blade. The bucket further comprises a front screen rotatable relative to the bottom screen having a main portion and an angled bottom portion. The front screen is positionable to a closed position proximate the front edge of the bottom screen such that the front edge of the bottom screen extends past the angled bottom portion of the front screen.

  • Patent number: 5743030
    Abstract: A loader such as a front end loader is provided with dam shell type bucket having a blade section, and collecting section pivoted thereon. The collecting section has a separating section having a separating surface curved on an are centered on pivotal axis of the collecting section and positioned relative to the leading edge of the blade section so that it tends to wipe clean the separating surface as it passes thereby when the relevant bucket sections are relatively pivoted from a screening position to a closed position. When the clam shell is in the screening position, the separating section forms at least a portion of the bottom of the bucket. A sifting screen for sifting finer material may also be provided as a dam at the free end of the collecting section.
