Abstract
The invention concerns a cutter head (8) for loosening and removing under water obstacles (12), the cutter head hangs on cables (5, 7) to flexibly support the cutter head, the cutter head is coupled to a flexible pressure pipe (6) and the cutter head comprises a pump for transporting loosened material through the flexible pressure pipe, a suction mouth (25) connected to the pump, and in front of the suction mouth two counter rotating cutters (10) with cutter teeth (16) and parallel cutter rotation axes (35). In accordance with the invention, each rotating cutter has at least two rings (17) perpendicular to the cutter rotation axis, the rotating cutter teeth are mounted on the outer circumference of the rings and the rings intersect in front of the suction mouth.
IPC Classes ?
- E02F 3/20 - DredgersSoil-shifting machines mechanically-driven with digging wheels turning round an axis with tools that only loosen the material
- E02F 5/00 - Dredgers or soil-shifting machines for special purposes
- E02F 3/92 - Digging elements, e.g. suction heads

Abstract
The application is directed to a system for recovering immerged sediments (3) from a concession and discharging them. From a free sailing extraction ship (1) a mixture of water and sediment is sucked by a submerged pump unit through a flexible hose (7) adapted to be rolled on a rotative reel (5) disposed on said extraction ship, while the ship is sailing over the concession. The sucked mixture is then immediately delivered to one of a series of free sailing carrier and transport units (27) that sails alongside.
IPC Classes ?
- E02F 3/88 - DredgersSoil-shifting machines mechanically-driven with arrangements acting by a sucking or forcing effect, e.g. suction dredgers
- E02F 3/90 - Component parts, e.g. drives, control devices
- E02F 3/92 - Digging elements, e.g. suction heads
- E02F 7/02 - Conveying equipment mounted on a dredger
- E02F 9/06 - Floating substructures as supports
