<p>A bucket wheel assembly particularly adapted for use on a suction dredge for dredging fine particulate materials. The cutter wheel assembly (10) comprises a support arm (11) on which is rotatably mounted a hub (12) carrying a pair of substantially parallel circular plates (14). Each of the plates (14) is formed with a number of apertures (18) each of which is bounded on its trailing edge by an outwardly projecting scoop (19). The space (16) between the plates is enclosed by a housing (15) extending between the circumferential edges of the plates (14). A suction inlet pipe (17) extends into the space (16). Water jets (24) and water inlets (22) direct water around the space (16) into the inlet pipe (17) sweeping with it the solid particulate material drawn into the space (16) by the scoops (19).</p> |
