Abstract
The present vibrating bucket screen attachment for cleaning beaches and for being mounted on mobile machines such as skid-steer loaders includes an outer excavating bucket with a sand-scooping blade and runners on the outer bucket for supporting the outer bucket relative to the beach. An inner vibrating screen bucket is resiliently mounted in the excavating bucket and includes a hydraulically operated vibrator. Resilient bumper pad mounts disposed between the inner and outer buckets suppress the vibrations of the inner vibrating bucket relative the outer excavating bucket. A floor screen portion of the inner bucket is mounted above bottom, sand-engaging portions of the outer bucket such that the screen portion is spaced from the surface of the beach to vibrate freely during the separation of sand from litter.
