Abstract

Die Erfindung betrifft eine Siebvorrichtung mit einem Rost, der mehrere Roststäbe (11) aufweist, die durch an ihnen befestigte, die Spalten zwischen den Roststäben überbrückende, flexible Siebelemente (3) verbunden sind und bezweckt die Lösung der beiden Auf­ gaben, einerseits die Siebleistung zu erhöhen und ander­ seits die Massenkräfte innerhalb des Rostes weitgehend zu kompensieren. Dies wird dadurch erreicht, daß die Roststäbe (11) in einem Rahmen (1) in mehreren Richtun­ gen, vorzugsweise in zwei einander entgegengesetzten Richtungen, in einer Ebene senkrecht zu ihren Längs­ achsen beweglich gelagert und einzeln an beiden ihrer Enden mit einem sie in Bewegung versetzenden Antrieb (18,19,24;31,35) versehen sind. Hiebei können die Rost­ stäbe (11) im Rahmen (1) federnd gelagert und die An­ triebe Unwuchtantriebe (18,19,24;38) sein, oder die Roststäbe sind beiderseits auf rotierenden Exzentern (31) gelagert und gegen eine Verdrehung um ihre Längsachse verhindert. The invention relates to a screening device a grate which has a plurality of grate bars (11) which by attached to them, the gaps between the Flexible sieve elements bridging grate bars (3) are connected and intended to solve the two problems gave, on the one hand to increase the screening performance and on the other the mass forces within the grate largely to compensate. This is achieved in that the Grate bars (11) in a frame (1) in several directions gene, preferably in two opposite to each other Directions, in a plane perpendicular to their longitudinal axially movable and individually on both of them Ends with a drive that sets them in motion (18,19,24; 31,35) are provided. You can use the rust rods (11) in the frame (1) resiliently mounted and the drives are unbalance drives (18,19,24; 38), or the Grate bars are on both sides on rotating eccentrics (31) stored and against rotation about its longitudinal axis prevented.
