Die Erfindung betrifft ein Lamellensieb für Mähdrescher, bestehend aus einer Vielzahl einzelner Lamellen und einem schwingenden Siebkasten, in welchem die Lamellenachsen zwischen den Seitenwänden bzw. Längsrippen des Siebkastens drehbar gelagert sind. Durch Drehen der Lamellenachsen können die mit diesen verbundenen Lamellen in ihrer Neigung verändert werden, wodurch Stärke und Richtung des von unten gegen die Siebfiäche herangeführten Reinigungswindes und damit dessen Einfluß auf das über die Siebfläche fließende Gut geregelt werden kann. Ein derartiges Lamellensieb ist bereits bekannt.The invention relates to a lamellar sieve for combine harvesters, consisting of a large number of individual lamellae and a vibrating screen box, in which the lamella axles between the side walls or longitudinal ribs of the screen box are rotatably mounted. By turning the slat axes you can the slats connected to these are changed in their inclination, whereby strength and Direction of the cleaning wind brought in from below against the screen surface and thus its influence can be regulated on the material flowing over the sieve surface. Such a lamellar sieve is already known.

Der Erfindung liegt die Aufgabe zugrunde, die gute Wirkung dieses bekannten Lamellensiebes dadurch zu verbessern, daß die über die Siebfiäche fließende Schicht aus Stroh, Spreu und Körnern, die bei hohen Mähdrescherleistungen oft sehr hoch ist, zusätzlich zur Schwingbewegung des Siebkastens aufgelockert wird.The invention is based on the object, thereby the good effect of this known lamellar sieve to improve that the layer of straw, chaff and grain that flows over the screen surface is often very high at high combine harvester outputs, loosened up in addition to the vibratory movement of the screen box will.

Hierzu sind erfindungsgemäß zwischen den Lamellenachsen, achsparallel zu diesen, an sich bekannte rechenartige, mehrere Lamellenachsen übergreifende Schüttlerfinger angeordnet, deren Achsenenden mittels Kurbeln, Winkelhebeln od. dgl. an unbewegten Gehäuseteilen der Maschine drehbar gelagert sind. Die Schütilerfinger führen also zusätzlich zur Schwingbewegung des Siebkastens auf- und abschwingende Bewegungen aus.For this purpose, according to the invention, between the lamella axes, axially parallel to them, are known per se Rake-like, multiple lamellar axes overlapping shaker fingers arranged, their axis ends by means of cranks, angle levers or the like. Rotatably mounted on stationary housing parts of the machine are. The Schütilerfinger also lead up and down to the oscillating movement of the screen box downward swinging movements.

Der Grundgedanke der Erfindung, der zahlreiche Ausführungsinöglichkeiten zuläßt, ist schematisch an einem Beispiel dargestellt.The basic idea of the invention, which allows numerous possible embodiments, is shown schematically shown in an example.

In dem schwingenden Siebkasten 1 sind die Lamellenachsen 2 zwischen den Seitenwänden 3 bzw. den Längsrippen 4 drehbar gelagert. Achsparallel zu den Lamellenachsen 2 sind zwischen diesen mehrere Lamellensäeb für MähdrescherIn the vibrating screen box 1, the lamella axes 2 are between the side walls 3 and the longitudinal ribs 4 rotatably mounted. There are several axially parallel to the lamellar axes 2 between them Lamellar seeders for combine harvesters

Achsen S mit an diesen befestigten rechenartigen Schüttlerfingern 6 gelagert, deren Enden mittels Kurbeln 7 an der unbewegten Gehäusewand 8 der Maschine drehbar gelagert sind. Infolge der in Pfeilrichtung 9 erfolgenden Bewegung des Siebkastens 1 und der ortsfesten Lagerung der Kurbein 7 schwingen die Schüttlerfinger 6 auf und ab.Axes S are mounted with rake-like shaker fingers 6 attached to them, the ends of which are rotatably mounted on the stationary housing wall 8 of the machine by means of cranks 7. As a result of the movement of the sieve box 1 taking place in the direction of arrow 9 and the stationary mounting of the crank legs 7, the shaker fingers 6 swing up and down.
