Abstract

A cutter head consisting of a cutter carrier (5), a cutter (6) and a crushing surface is designed so that the cutter (6) penetrates into the crop at the cutting point (10) at a steep cutting angle and that there follows, at a short distance (a) from the cutter tip (10) corresponding approximately to the thickness of a cereal grain, a breast (12) which forms an angle of approximately 90 DEG and which breaks up the cut material and smashes included grains. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Messerkopf für Feldhäcksler, wie er in der DE-PA 35 26 398.9 offenbart ist.The invention relates to a cutter head for forage harvesters, as disclosed in DE-PA 35 26 398.9.

Nach dieser Erfindung ist es möglich, das Erntegut nicht nur zu schneiden, sondern auch anzuschlagen und aufzufasern. Wenn das Erntegut, wie z. B. bei Getreide, kleine Körner enthält, ist es dagegen schwierig, mit einer Einrichtung dieser Art auch die Körner zu brechen und damit in einen für das Tier verdaulichen Zustand überzuführen.According to this invention it is possible not to harvest the crop not only to cut, but also to cast and unravel. If the crop such. B. in cereals, small grains contains, however, it is difficult with one facility this way of breaking the grains and into one to convert the animal into a digestible state.

Die zusätzliche Erfindung macht es sich zur Aufgabe, auch diese Forderung zu erfüllen. Dazu ist es nötig, an geeigneter Stelle einen so engen Spalt für das Schnittgut zu erzeugen, daß die darin enthaltenen Körner zwangsläufig gebrochen werden. Dies wird erfindungsgemäß dadurch erreicht, daß die Brust an der Unterkante des Messers bis auf eine Entfernung (a) an die Spitze des Messers heranreicht, die etwa der Dicke eines zu bearbeitenden Getreidekornes oder weniger entspricht.The additional invention makes it its task to meet this requirement. For this it is necessary to create such a narrow gap for the clippings at a suitable point that the grains contained therein are inevitably broken. This is achieved according to the invention in that the breast on the lower edge of the knife extends up to a distance ( a ) to the tip of the knife which corresponds approximately to the thickness of a grain of grain to be processed or less.

Damit die im Erntegut enthaltenen Körner beim Schnitt nicht in den Innenraum der Häckseltrommel oder dergleichen ausweichen können, ist vorgesehen, daß die Brust mit der Unterkante des Messers einen Winkel von etwa 90° bildet.So that the grains contained in the crop are not cut dodge into the interior of the chopper drum or the like can, it is provided that the chest with the lower edge of the knife forms an angle of approximately 90 °.

Um noch mehr reibende und quetschende Kanten zu schaffen, soll erfindungsgemäß die Brust mit einem Riffelmuster oder dergleichen versehen sein. To create even more rubbing and squeezing edges, According to the invention, the breast with a corrugated pattern or the like.  

Die Abbildung zeigt einen Messerkopf nach der Erfindung im Schnitt, wie er bei einem Trommelfeldhäcksler verwendet wird, ohne darauf beschränkt zu sein.The figure shows a cutter head according to the invention on average, as used in a drum chopper without being limited to it.

Das Messer (6) dringt beim Schnitt mit seiner freien Spitze (10) in den Gutstrang (4) ein. Dadurch werden die Halme und teilweise auch eingelagerte Körner durchgetrennt. Die abgeschnittenen Teile werden aber durch die Brust (12) der Quetschleiste (11) am Ausweichen gehindert und besonders beim Vorübergehen an der Gegenschneide (3) gehäckselt, gefasert und gebrochen. Bei der Bearbeitung von Getreide ist es zweckmäßig, die Brust (12) bis auf einen Abstand von 2-3 mm von der Messerspitze (10) einzustellen.The knife ( 6 ) penetrates into the crop strand ( 4 ) with its free tip ( 10 ). This separates the stalks and some of the grains that have been stored. The cut-off parts are prevented from evading by the breast ( 12 ) of the squeeze bar ( 11 ) and are chopped, fibred and broken, particularly when passing the shear bar ( 3 ). When processing grain, it is advisable to adjust the breast ( 12 ) to a distance of 2-3 mm from the knife tip ( 10 ).

Eine Riffelung an der Brust schafft zusätzliche Kanten, die die Zerkleinerungswirkung noch unterstützen.A ribbing on the chest creates additional edges, that still support the crushing effect.

Für die Aufrechterhaltung dieser Wirkung ist es wichtig, daß die Quetschleiste (11) durch nicht näher dargestellte Mittel immer auf einen möglichst genauen Abstand zur Messerspitze eingestellt werden kann.In order to maintain this effect, it is important that the squeeze bar ( 11 ) can always be adjusted to the most exact possible distance from the knife tip by means not shown in detail.
