Zusammenfassung:	The excavated material has the water extracted and is then brought by floating conveying belts onto land. A blind base is installed beneath the draining screen of a screening machine to collect up the mixture of water and fine sand which is then ejected in the delivery direction and taken up in a wash trough forming the separating bed of a hydro-belt separator. Independent claim describes device with draining screen and blind base (5) covering entire surface beneath draining cover (4). An ejector (8) leads to a hydro-belt separator (9) which comprises an endless conveyor belt (10) with wash trough (11) and rising part (12) leading away from same.
