Improvements in and relating to dredging apparatus
This present invention relates to improvements in and relating to dredging apparatus. In particular, the invention relates to a suction head for a dredging device for relocating matter, such as matter in the form of particulate matter and/or fluid by sucking the particulate matter from a bed of a body of water. The suction head comprises a first conduit having an inlet; a second conduit having an inlet and an outlet, the second conduit being in series and in fluid communication with the first conduit, the outlet of the second conduit opening to the inlet of the first conduit via a mixing region; a third conduit having an inlet and an outlet, the outlet of the third conduit opening to the first conduit via a restriction and the mixing region, wherein a fluid may be fed under pressure through the inlet of the third conduit and conveyed to the mixing region via the restriction to cause a reduction in the pressure of the fluid passing into the mixing region, the reduction in pressure of the fluid causing matter to be sucked through the inlet of the second conduit and conveyed though the second conduit to the mixing region, the matter being entrained with the fluid and exiting the mixing region via the first conduit; and means for promoting a generally helical flow of the fluid through the restriction.
