Description

Gegenstand des Patentes 496 099 ist ein Siebbelag, insbesondere für Dreschmaschinen, bei dem die Vorschubleisten aus dem Blech herausgefaltet sind und der tote Raum durch Zusammenrücken der Fußkanten der Schenkel der Vorschubleisten möglichst verringert ist. Die Seitenwandungen der Vorschubleisten reichen bei dieser Ausführungsform auf ihrer ganzen Länge bis zur unteren Siebfläche.The subject of patent 496 099 is a screen covering, in particular for threshing machines, in which the feed bars are folded out of the sheet metal and the dead space through Moving together of the foot edges of the legs of the feed bars is reduced as possible. The side walls of the feed bars extend in this embodiment on their entire length to the lower sieve surface.

Die Erfindung verbessert die in dem Patent 496 099 geschützte Erfindung dadurch, daß die Lochung des Siebbleches sich über einen Teil der Schenkel der Vorschubleisten erstreckt. Dieses hat den Vorteil, daß längere Strohhalme, die mit dem einen Ende zwischen zwei Vorschubleisten kommen, nicht so leicht abknicken, da der Winkel, den ein solcher Strohhalm gegenüber der Verbindungslinie der oberen Vorschubkanten bildet, bei einerThe invention improves upon the invention protected in patent 496,099 by that the perforation of the screen plate extends over part of the legs of the feed bars extends. This has the advantage that longer straws with one end between two feed bars come, do not bend so easily, because of the angle one such Straw opposite the connecting line of the upper feed edges forms, at one

ao Ausführungeform der Vorschubleisten in Brückenform geringer ist, als wenn die Vorschubleisten geschlossen bis zu der unteren Siebfläche herabreichen würden.ao execution form of the feed bars in bridge form is less than when the feed bars when closed, would reach down to the lower screen surface.

Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, bei der aus dem Siebbleeh 1 Vorschubleisten 2 herausgefaltet sind. Die Sieböffnungen 3 enden nicht an der unteren Knicklinie der Vorschubleisten, sondern ragen in die Schenkel 2a, 2b der Vorschubleisten 2 hinein.In the drawing, an embodiment of the invention is shown in which 1 feed strips 2 are folded out of the Siebbleeh. The sieve openings 3 do not end at the lower kink line of the feed bars, but protrude into the legs 2 a , 2 b of the feed bars 2.
