Description

Die bekannten Andrückvorrichtungen, die die Bewegung des Messers mitmachen und eine Schubstange mit Mitnehmer haben, wirken ungenügend, da die Mitnehmer zu kurz sind und außerdem das federnde Andrücken der Messerschiene nur in der Nähe des Schubstangenkopfes erfolgt. Daher kann das Gras zwischen Messer und Fingerflächen gelangen, was den Gang der Maschine erschwert. The well-known pressing devices that join the movement of the knife and have a push rod with a driver, are insufficient because the driver is too short and also the resilient pressing of the knife bar only in the vicinity of the Push rod head takes place. Therefore the grass can get between the knife and the palms of the fingers arrive, which makes it difficult for the machine to run.

Das Neue gemäß der vorliegenden Erfindung besteht darin, daß an der Schubstange lange starre Andrückdaumen sitzen, die auf das genaueste zwangläufig eingestellt werden können, wodurch ein Heben des Messers von den Fingerflächen ausgeschlossen ist und somit leichter Gang und saubere Arbeit der Maschine erzielt wird.The novelty according to the present invention is that on the push rod long, rigid pressure thumbs that are inevitably adjusted to the greatest possible precision can, whereby lifting the knife from the finger surfaces is excluded and thus easier operation and clean work of the machine is achieved.

Einzelne der Daumen erhalten Verlängerungen, die hinten gegen eine Gleitfläche ao drücken. Die Einstellung aller Daumen erfolgt gleichzeitig durch Heben der Lager für die Andrückdaumenstange.Some of the thumbs have extensions that ao at the back against a sliding surface to press. The adjustment of all thumbs is done at the same time by lifting the bearings for the thumb bar.

Die Zeichnung zeigt ein Stück der Schneidvorrichtung mit dem Andrückdaumen in Abb. 1 in Seitenansicht und in Abb. 2 in Aufsicht.The drawing shows a piece of the cutting device with the pressure thumb in Fig. 1 in side view and in Fig. 2 in plan view.

Jede · Messerklinge hat einen genau einstellbaren Druckdaumen a, welche alle an einer Welle c befestigt sind und mit demEach knife blade has a precisely adjustable pressure thumb a, which are all attached to a shaft c and with the

Messer durch die Schubstange gemeinsamen gleichen Hub haben. Der Gegendruck wird, durch sechs bis acht Gleithebel «(Verlängerungen α1 von Druckdaumen α), die auf dem Fingerbalken g schleifen, bewirkt. Das genaue Einstellen und auch Nachstellen der Druckdaumen infolge Verschleißes wird durch das einfache Nachstellen der Lager ei der Stange c bewirkt.Knives have the same stroke in common through the push rod. The counterpressure is brought about by six to eight sliding levers «(extensions α 1 of pressure thumb α) that slide on the finger bar g . The exact setting and readjustment of the pressure thumb due to wear is effected by simply readjusting the bearings ei of the rod c .

ίο Die Befestigungsweise der Druckdaumen a und a1 erfolgt durch Klemmschrauben; die Daumen können daher nach jeder Klingenteilung beliebig eingestellt werden. Die Befestigung und die Nachstellung der Lager d für die Daumenwelle c wird durch Lockern der Stellschraube e und durch Anziehen der Schraube/ bewirkt.ίο The fastening of the pressure thumbs a and a 1 is done by clamping screws; the thumbs can therefore be adjusted as required after each blade division. The mounting and readjustment of the bearings d for the thumb shaft c is effected by loosening the adjusting screw e and tightening the screw /.

Eine gehärtete Stahlplatte kann als Lauffläche für den Gegendruckhebel α1 dienen.A hardened steel plate can serve as a running surface for the counter pressure lever α 1 .

Dieselbe ist an einem Ende beweglich befestigt, um die Druckdaumen bei dem Auswechseln der Messer zu lockern. Das Ausschwingen der Stahlplatte geschieht nach dem Lösen der Befestigungsschrauben.The same is movably attached at one end to the pressure thumbs when changing to loosen the knife. The steel plate swings out after loosening the fastening screws.
