Es wird hierbei das Dreschgut durch die . Fördereinrichtung und die Flegclschläge zu einer derart festen Schicht zusammengepreßt, daß die Schlagwirkung gar nicht an im Innern der Schicht liegende Ähren herankommt. Ein Durcharbeiten der festen Dreschgutschicht unter etwaigem Auflockern findet nicht statt.It is here the threshed by the. Conveyor and the Flegclschlag compressed such a firm layer that the impact effect does not even affect im Ears lying inside the layer come up. Working through the solid layer of threshed material, possibly loosening it does not take place.

Die Erfindung, die in drei Ausführungsformen in Abb. 1 bis 3 schematisch dar- gestellt ist, beseitigt diese Mängel und sichert einwandsfreien Drusch, ohne die Halme (das Stroh) zu zerstören.The invention, which is shown schematically in three embodiments in Figs. 1 to 3 is set, eliminates these deficiencies and ensures perfect threshing without the stalks (the Straw).

Das Dreschgut tritt in Richtung von a in die Maschine ein, gelangt unmittelbar oder durch Förderwalzen b oder sonst einer bekannten Weise befördert und geführt in den Bereich der Schlagwirkung der um die Welle c in der Pfeilrichtung umlaufenden Dreschflegel d, wird von diesen getroffen, weitergezogen und verläßt die Maschine unmittelbar oder durch Förderwalzen / o. dgl. in Richtung des Pfeiles e. The threshed material enters the machine in the direction of a, is conveyed directly or by conveyor rollers b or in some other known manner and is guided into the area of impact of the flail d rotating around the shaft c in the direction of the arrow, is hit by the flail, pulled on and leaves the machine directly or through conveyor rollers / o. The like. In the direction of arrow e.

In Abb. τ sind zwei gegenläufige, fest mit ■ den Wellen verbundene Flegelsätze so augeordnet, daß das Dreschgut zwischen je einem Flegel jedes Flegelsatzes von beiden Seiten gleichzeitig geschlagen, gehalten und Aveitergeführt wird. Drehen sich die beiden gegenläufigen Flegelsätze weiter, so schlägt in kurzer Entfernung" von der ersten Schlagstelle das nächste Flegelpaar wieder von beiden .Seiten gleichzeitig das Dreschgut zusammen. In Fig. Τ there are two opposite directions, fixed with ■ the shafts connected sets of flakes so arranged that the threshed between each one Flails of each set of flails were beaten, held and led on from both sides at the same time will. If the two counter-rotating sets of flakes continue to turn, it strikes a short distance from the first impact point the next pair of flails again from both sides together the threshed crop.

Durch diese gleichzeitig von beiden Seiten im Sinne der Bewegungsrichtung wirkenden Stöße wird das Dreschgut in eine doppelt wellenartige Form nach Abb. 4 zusammengedrückt und in sich zusammengeschoben. Hierbei springt alles Korn aus den Ähren, soweit es noch nicht unter Einwirkung der Schläge herausgefallen ist.By acting simultaneously from both sides in the sense of the direction of movement The threshed material is compressed into a double wave-like shape as shown in Fig. 4 and pushed together. Here all the grain jumps out of the ears, as far as it is not yet under the influence of the Blows fell out.

In Abb. 2 sind die an der Welle sitzenden Flegel an verschieden langen Armen befestigt. Hierdurch wird die wellenartige Bewegung des vorwärts gehenden Dreschgutes noch stärker, da nacheinander je ein kurzer und ein langer Flegel zur Wirkung miteinander kommen. Es läuft die Dresch-In Fig. 2, the flails on the shaft are attached to arms of different lengths. This makes the wave-like movement of the forward threshing material even stronger, as one after the other short and long flail come into effect together. The threshing is running

Claims

good layer here in a double wave according to Fig. 5.

The two mentioned arrangements with flails fixedly attached to the shaft are Can only be used where the threshed material enters the machine in an equally high layer can be introduced and passed through the same.

But since the ears of wheat have different stalk thicknesses above and below, the stalks compressing yourself to different degrees under the blows, it's almost technically impossible to keep completely the same layer heights, so the striking tools must be (Flegel) can adapt to these different strengths in their distance from their axes of rotation.

This can be achieved in that the flails are not rigidly connected to their axes of rotation, but are arranged in a known manner so resiliently on their axes that they automatically adapt to the different layer thicknesses with the same impact forces. The flails can , for example, be connected to their shaft by somehow shaped and mounted ribbon springs which, depending on the resistance, bend more or less, more or less tangentially to the circle of impact.

The impact force of the flail must then be due to its centrifugal force and the resistance to bending the springs can be achieved.

Without touching the essence of the invention, the coming to use Springs can also be shaped and stored differently,

Even so, the blows are softer when using springs, falls as a result of the Wave-like processing of the threshed crop, removing all grain from the ears, even if thicker layers are allowed through will.

Since the relatively weak and softly mounted flails have to bring about the advance of the wood to be turned, but a sliding of the flails on the stalks delays the advance, the latter can be switched off if the flails alternate against 'somehow shaped and supported pressure hunting surfaces' rotating with the other shaft work, opposing the sliding of the \ threshed stronger resistance. This is shown schematically in Fig. 3.

With the same layer heights, you can; here again flails and hitting surfaces firmly be connected to their axes of rotation, while the flails at changing layer heights or the striking surfaces or both are resilient, as mentioned above for the flails must be. '"'. '. .- ■■ -;

The undulating 'working through of the threshed crop is preserved in every case and ensures good threshing without destroying the straw. '- ....'

In order to achieve a good threshing effect, a straw length of about 6 to 8 mm must be used Blow the flail come. Therefore the flails have to be placed very close to one another, if they are to thresh and feed at the same time.

If, on the other hand, the threshed material is fed through some known conveying device, such as rollers, between belts or in some other way, into, through or out of the machine, and the threshed material is held in this conveying device while it is' ^! of the flails. is processed, the rotating flails can only be used to loosen the grain from the ears. will. The threshed material can then be struck in any short intervals by means of a slowly running conveyor device and fast running flails, without the flails themselves being used to advance the threshed material. .;
