Abstract
To mechanically assist the suction action of a dredge head in dislodging particles embedded, e.g., on the ocean floor, a plurality of fingers extend downwardly from along the upper edge of an obliquely downwardly and forwardly facing nozzle opening. The fingers are resiliently connected to the nozzle and thus are capable of being bent downwardly so as to be juxtaposed across and thus temporarily block, the nozzle opening, whereby the intake of oversized particles is prevented.
