Das durch das Patent 516 331 geschützte Sieb zum Trennen der Spreu vom Kurzstroh ist in einem am hinteren Ende der Dreschmaschine abnehmbar angebrachten Kasten unterhalb oder " 5 oberhalb eines in der Verlängerung des Strohschüttlers liegenden Nachschüttlers angeordnet, wobei das Trenngut unmittelbar auf das Trennsieb fällt bzw* durch eine Hubvorrichtung auf das Sieb befördert wird. to Durch die Erfindung soll die Spreuabsonderung dieses Siebes dadurch erhöht werden, daß der Nachschüttler nach Art der bekannten Rollschüttler ausgebildet wird, unter dessen oberem Trum ein Sieb zum Durchlassen der Spreu vorgesehen ist und unter dessen unterem Trum, wie bekannt, ein ungelochter Boden angeordnet ist, über den die Spreu durch die Leisten des Rollschüttlers auf einen schräg abfallenden Boden befördert wird, der die Spreu in den Bereich des Windstromes der Dreschmaschine führt. Weiter ist zu dem genannten Zweck über dem Trennsieb eine gelochte Haube angeordnet, durch welche der von der Dreschmaschine kommende Wind, welcher mit einem Gemisch von Kürzstroh und Spreu beladen ist, strömt und in der in bekannter Weise ein Fangtuch aufgehängt ist, welches das Kurzstroh und die Spreu von dem Windstrom trennt und diese Teile auf das Trennsieb ablegt. Die Erfindung ist in der Zeichnung in Fig. 1 in einem Längsschnitt und in Fig. 2 in einem Querschnitt dargestellt. Das von dem Strohschüttler δ der Dreschmaschine« kommende Stroh wird auf das obere Trum des RoIl-Schüttlers u geworfen und von diesem nach außen befördert. Unterhalb des oberen Trums* ist das Siebblech υ angeordnet, durch welches die Spreu auf den Boden w fällt. Auf diesem wird die Spreu durch das untere Trum des RoIl-Schüttlers 11 nach dem nach dem Schüttelsieb cschräg abfallenden Boden ζ befördert und gelangt so in den aus der Dreschmaschine über die Siebe c, d strömenden Wind. Dieser bläst das Kurzstroh und die Spreu in den durch eine dachförmig geformte Haube y aus gelochtem Blech gebildeten Raum λ;. Der Wind kann durch die Löcher der Haube y entweichen, so daß Kurzstroh und Spreu in gut gelockertem Zustande auf die Trennsiebe η gelangen. Das Hinausblasen der Spreu aus dem Raum wird in an sich bekannter Weise durch ein lose hängendes Tuch s ο. dgl. verhindert. Die Auflockerung des Gutes wird ferner durch Finger oder Rechen t verstärkt, die in an sich bekannter Weise eine schwingende Bewegung oberhalb der Siebe η ausführen. Die Spreu verläßt durch die Löchungen der Siebe η den Raum % nach unten in den Abführkasten i, während das Kurzstroh nach hinten aus der Maschine herausbefördert wird. Patentafseeüche:The sieve for separating the chaff from the short straw, protected by patent 516 331, is arranged in a detachable box at the rear end of the threshing machine below or "5 above a post-shaker located in the extension of the straw shaker, whereby the material to be separated falls directly onto the separating sieve or * The invention is intended to increase the chaff secretion of this sieve in that the shaker is designed in the manner of the known rotary shaker, under whose upper run a sieve is provided to let the chaff through and under its lower run As is known, an unperforated floor is arranged, over which the chaff is conveyed through the strips of the roller shaker onto a sloping floor, which guides the chaff into the area of the wind flow of the threshing machine Hood arranged through which the threshing Machine coming wind, which is loaded with a mixture of short straw and chaff, flows and in the known manner a collecting cloth is suspended, which separates the short straw and the chaff from the wind stream and deposits these parts on the separating screen. The invention is shown in the drawing in Fig. 1 in a longitudinal section and in Fig. 2 in a cross section. The straw coming from the straw shaker δ of the threshing machine is thrown onto the upper run of the roller shaker u and conveyed to the outside by this. The sieve plate υ through which the chaff falls onto the floor w is arranged below the upper run *. On this, the chaff is conveyed through the lower run of the RoIl shaker 11 to the bottom ζ sloping at an angle after the vibrating sieve and thus enters the wind flowing out of the threshing machine over sieves c, d. This blows the short straw and the chaff into the space λ formed by a roof-shaped hood y made of perforated sheet metal. The wind can escape through the holes in the hood y so that short straw and chaff reach the separating sieves η in a well loosened state. The chaff is blown out of the room in a manner known per se by means of a loosely hanging cloth s ο. like. prevented. The loosening of the material is further enhanced by fingers or rakes t, which carry out an oscillating movement above the sieves η in a manner known per se. The chaff leaves the space% down through the holes in the sieves η into the discharge box i, while the short straw is conveyed out of the machine to the rear. Patentafsee kitchen: 1. Sieb zum Trennen der Spreu vom Kurzstroh bei Dreschmaschinen, bei denen Spreii und Kurzstroh gemeinsam durch ein unter dem Strohschüttler liegendes Schüttelsieb nach hinten aus der Maschine herausbefördert werden, Zusatz zumPatent5i6 331, dadurch gekennzeichnet, daß- der Nachschüttler als Rollschüttler ausgebildet ist, dessen oberes Trum über einem die Spreu : hindurchlassenden Sieb und dessen unteres Trum über einen ungelochten Boden läuft, hinter dem ein nach dem Schüttelsieb der Dreschmaschine abfallender Rücklaufboden angeordnet ist.1. Sieve for separating the chaff from the short straw in threshing machines, in which the chaff and short straw are conveyed out of the machine to the rear through a vibrating sieve located under the straw shaker, addition to the patent 5i6 331, characterized in that the shaker is designed as a roller shaker upper run over a chaff: running through transmitting wire and whose lower run over a non-perforated bottom, behind which a falling after the vibrating of the threshing return tray is arranged. 2, Sieb nach Anspruch 1, dadurch gekennzeichnet, daß über dem unter dem Rollschüttler liegenden Trennsieb (n) für die Spreu eine gelochte Haube angeordnet ist, in der in bekannter Weise ein Fangtuch aufgehängt isti2, sieve according to claim 1, characterized in that a perforated hood is arranged above the separating sieve (s) for the chaff located under the rotary shaker, in which a collecting cloth is suspended in a known manner Hierzu 1 Blatt Zeichnungen1 sheet of drawings
