Self Cleaning Collection Apparatus and Method

摘要

A self cleaning collecting apparatus and method are provided for the collection of seafloor material. The collecting apparatus, which operates on a seafloor, has a plurality of rotating discs in front of a slurry suction pipe with clearing members located between adjacent discs. Any oversize material lodged in the discs during collection is dislodged by the one or more clearing members and prevented from entering the slurry suction pipe, thus preventing blockages caused by oversize material congesting the slurry suction pipe.
