Description

Zum Schneiden von Stroh od. dgl. verwendet man Häckselmaschinen, die mit einem Schneidrad oder Schaeddbalken versehen sind, an derenMesserarmen je ein Messer befestigt ist. Mittels einfacher Getriebe werden derartige Maschinen auf die gewünschte Schnittlange eingestellt. Für große Schnittlängen (z.B. für Streustroh) wird es erforderlich, kompliziertere Getriebe zu verwenden, wodurch die Maschinen nicht nur teuer werden, son- dem auch größerem Verschleiß unterliegen.. Man hat daher versucht, einfache Häckselmaschinen zu bauen, bei denen ein Messer entfernt werden kann, wodurch die doppelte Schneidlänge erreicht wird. Derartige Maschinen unterliegen aber beachtlichen Schwierigkeiten. So schlägt z. B. der vom Messer befreite Arm auf das aus der Maschine herausragende Stroh und verursacht nicht selten einen Maschinenbruch.For cutting straw od. The like. You use chopping machines with a cutting wheel or Schaeddbalken are provided on their knife arms a knife is attached to each. By means of simple gears such machines are on the desired cutting length set. For long cutting lengths (e.g. for straw) it is necessary to to use more complicated gears, which not only make the machines expensive, but also which are also subject to greater wear. Attempts have therefore been made to make simple chopping machines where a knife can be removed, making it twice the cutting length. However, such machines are subject to considerable difficulties. So z. B. the knife freed arm on the straw protruding from the machine and not infrequently caused one Machine breakdown.

Ferner ist es bekannt, das Messerad von Häckselmaschinen mit keilförmigen Messerplatten auszurüsten. Auf den Messerplatten werden die Schneidmesser angebracht. Wenn Langhäcksel geschnitten werden soll, so wird ein Messer entfernt, und die keilförmigen Messerplatten müssen beim Schneiden durch den Strang des zu schneidenden Gutes hindurchstoßen. Die schlagartige Wirkung kann dabei auch durch die keilförmige Ausbildung der Messerplatten nicht beseitigt werden, da die Überwindung der Keilform je nach der Konizität der Messerplatte relativ viel Kraft erfordert. Das trifft ganz besonders zu, wenn sich zwischen zwei Messerplatten das zu schneidende Gut hindurchquetsohen muß. Auch bei einer derartigen Ausbildung eines Messerrades ist mit einem Brechen des Balkens zu rechnen.It is also known to equip the cutter wheel of chopping machines with wedge-shaped cutter plates. The cutting knives are attached to the knife plates. When long chaff is cut is to be removed, a knife is removed and the wedge-shaped cutter plates must be used when cutting push through the strand of material to be cut. The sudden effect can also be achieved by the wedge-shaped design of the Blade inserts cannot be eliminated, as the overcoming of the wedge shape depends on the taper of the Cutting insert requires a lot of force. This is especially true when there is between two Cutting inserts must squeeze through the material to be cut. Even with such a training a knife wheel is likely to break the bar.

Erfmdungsgemäß wird daher zur Behebung der Nachteile vorgeschlagen, daß das an dem abgekröpften Messerarm vorgesehene Schneidmesser an einem Messerhalter lösbar befestigt ist, der wiederum mit dem Messerarm lösbar und gelenkig verbunden ist. Vorteilhafterweise ist der Messerhalter in der aus der Arbeatelage herausgeschwenkten Lage verriegelibar, um eventuelle Unfälle zu vermeiden. Selbstverständlich sind die Schneidmesser, wie bei allen anderen bekannten Maschinen, lösbar mit den jeweiligen Tragarmen verbunden. Bei Verwendung erfindungsgemäßer zweiarmiger Messerräder kann, ohne die Häckselmaschine mehr zu belasten, der doppelte Vorschub durch bloße Abschwenkung des einen Messerhalfters erreicht werden. Ganz besonders vorteilhaft ist diese Vorrichtung zum Schneiden von Stroh.According to the invention it is therefore proposed to remedy the disadvantages that the cranked Knife arm provided cutting knife is releasably attached to a knife holder, the is in turn releasably and articulatedly connected to the knife arm. The knife holder is advantageous in the pivoted out of the Arbeatelage Lockable position to avoid possible accidents. Of course, the cutting knives are as with all other known machines, releasably connected to the respective support arms. When using two-armed knife wheels according to the invention, more can be done without the chopping machine to load, double the feed is achieved by simply swiveling the knife holster will. This device for cutting straw is particularly advantageous.

In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt, und zwar zeigt
' Fig. ι eine Vorderansicht eines Messerbalkens, Fig. 2 eine Draufsicht,
In the drawing, the invention is shown in an exemplary embodiment, namely shows
Fig. Ι a front view of a cutter bar, Fig. 2 is a plan view,

Fig. 3 einen Schnitt A-A nach Fig. 2.FIG. 3 shows a section AA according to FIG. 2.

Die beiden Messer 1, 2 sind mittels Schrauben 3 mit dem Balken 4 verbunden. Das Messer 1 ist dabei beweglich über einen Arm 5 an den Balken 4 angelenkt, wobei der Arm mittels Schrauben od. dgl. am Balken 4 lösbar befestigt ist und nach Lösen der Schrauben in eine unwirksame Lage verstellt werden kann, was man aus der in Fig. 3 gestrichelt gezeichneten Lage des Balkens 4 und Messers 1 ersehen kann. Das Messer 1 ist infolge des Messenscbutzes unwirksam.The two knives 1, 2 are connected to the beam 4 by means of screws 3. The knife 1 is movably articulated to the beam 4 via an arm 5, the arm by means of screws Od. The like. Is releasably attached to the beam 4 and adjusted to an inoperative position after loosening the screws can be what can be seen from the dashed line in Fig. 3 position of the bar 4 and Knife 1 can be seen. The knife 1 is ineffective due to the Messenscbutzes.
