 zugeführt. Die abgesetzten Stellen der Schnecke und die Einschnitte 21 haben den Zweck, das   Zurtickschwemmen   des Sandes möglichst zu verhüten und den Durchgang des Wassers zu erleichtern. 



   Dadurch, dass der   fortgeschwemmte   Sand der    Förderschnecke''fortwährend wieder   zugeführt und durch diese   schliesslich   durcl, das ganze Rohr hindurch gefördert wird, kann auch der Sand, der bei den gebräuchlichpn Maschinen beinahe vollständig verloren geht, gewonnen und gereinigt werden, wodurch eine   bedeutende Arbeits-und Materialersparnis   erzielt wird. 



   PATENT-ANSPRÜCHE : 
1. Kieswaschmaschine, dadurch gekennzeichnet, dass das die Förderschnecke enthaltende rotierende Rohr am tieferen Ende eine Trommel trägt, in welcher'eine Vorrichtung zum Auffangen des vom Wasser fortgeschwemmten Sandes und zum   Zurückführen   desselben nach der Förderschnecke vorgesehen ist.

 fed. The offset points of the screw and the incisions 21 have the purpose of preventing the sand from floating as far as possible and facilitating the passage of the water.



   Because the sand that was washed away is continuously fed back to the screw conveyor and is finally conveyed through the whole pipe through it, the sand, which is almost completely lost in conventional machines, can also be recovered and cleaned, which is a significant work -and material savings are achieved.



   PATENT CLAIMS:
1. Gravel washing machine, characterized in that the rotating tube containing the screw conveyor carries a drum at the lower end in which a device is provided for collecting the sand carried away by the water and for returning it to the screw conveyor.

Claims (1)

2. Kieswaschmaschine nach Anspruch 1, gekennzeichnet durch einen in der Trommel angeordneten, mit dem Innern des Förderrohres in Verbindung stehenden Sammelbehälter (18), dessen eine Seitenwandung eine Öffnung aufweist, so dass bei der Drehung der Trommel der in der letzteren befindliche Sand durch den Sammelbehälter aufgeschöpft und in das Förderrohr zurückgeleitet wird. 2. Gravel washing machine according to claim 1, characterized by an arranged in the drum, with the interior of the conveying pipe in communication collecting container (18), one side wall of which has an opening so that when the drum rotates, the sand in the latter through the Collection container is scooped up and returned to the conveyor pipe. 3. Kieswascbmaschine nach Anspruch 1, bei welcher eine Förderschnecke mit abgesetzten Gängen vorgesehen ist, dadurch gekennzeichnet, dass die einzelnen gegeneinander versetzten Enden der Schnecken teile durch mit Ausnehmungen versehene Querstege verbunden sind, welch letztere den Überlauf des Waschwassers gestatten, das Zurückschwemmen des Sandes aber verhindern. 3. Kieswascbmaschine according to claim 1, in which a screw conveyor is provided with stepped gears, characterized in that the individual mutually offset ends of the screw parts are connected by recessed cross webs, which latter allow the overflow of the washing water, but the backwashing of the sand prevent.
