Leicht lösbare Befestigung von Messern an rotierenden Schneidwerkzeugen«Easily detachable attachment of knives rotating cutting tools «

Die Erfindung bezieht" sich auf eine Vorrichtung, die dasfleichte Abnehmen von Messern von rotierenden Schneidwerkzeugen ermöglicht, Bekanntlich ist es notwendig, die Messer der Schneidvorrichtungen zu schärfen. Um diese Arbeit richtig auszuführen, müssen sie abgenommen werden. Auch sind sieöfters durch neue zu ersetzen. Es ist deshalb notwendig, daß die Messer leicht abgenommen werden können. Es ist aber auf der anderen Seite wieder von größter Wichtigkeit, daß die Messer unbedingt1 sicher am Mähaggregat gelagert werden, um ein Wegfliegen bei hoher Geschwindigkeit zu vermeiden.The invention relates "to a device which enables the easy removal of knives from rotating cutting tools. As is known, it is necessary to sharpen the knives of the cutting devices. In order to carry out this work properly, they must be removed. They also have to be replaced with new ones from time to time. It is therefore necessary that the knives can be easily removed, but on the other hand it is again of the greatest importance that the knives are absolutely 1 securely stored on the cutting unit in order to avoid them flying off at high speed.

Die Erfindung schlägt dazu vor, am rotierenden Mähaggregat einen -Zapfen mit Ausfräsungen vorzusehen. Das Messer wird am Zapfen gelagert und in den Ausfräsungen werden die Befestigungsplattem geführt, die von einer Feder in ihrer Lage betriebssicher gehalten werden. Beim Abnehmen der Messer werden die Befestigungsplatten aus ihren Führungen am Zapfen gezogen und das Messer kann abgenommen werden.The invention proposes to do this on the rotating cutting unit to provide a pin with milled holes. The knife is on Spigots are stored and the mounting plates are in the cutouts out of a spring in their position safe to operate being held. When removing the knives, the Fastening plates pulled out of their guides on the pin and the knife can be removed.

Die Abb. I und II zeigen eine beispielsweise Ausführungsform der Erfindung.Figs. I and II show an exemplary embodiment of the invention.

Abb. Ill und IV zeigen eine andere Form der Erfindung. Hier ist die Platte 7 um den Zapfen 8 drehbar gelagert und in ihrem inneren Ende Ja. als Feder ausgebildet. Der Schlitz 9 steht hier nach rückwärts und die Platte 7 wird durch Drehen in Fahrtrichtung aus dem Schlitz 10 geschoben. Um ein unbeabsichtigtes Verschieben zu verhindern, rastet der federnde Teil 7a in eine Auswölbung· des rotierenden Mähaggregates ein. Figs. III and IV show another form of the invention. Here the plate 7 is rotatably mounted about the pin 8 and Yes in its inner end. designed as a spring. The slot 9 is here to the rear and the plate 7 is pushed out of the slot 10 by rotating in the direction of travel. In order to prevent unintentional displacement, the resilient part 7a engages in a bulge of the rotating mowing unit.
