Description

Die Erfindung betrifft eine Vorrichtung an Mähmaschinen zum selbsttätigen Abkuppeln der Schubstange vom Messerbalken bei Störungen. Das Wesen der Erfindung besteht darin, daß der übliche an der Schubstange ausgebildete Kugelzapfen zwischen zwei federnde, mit Lagerpfannen versehene Stahlplatten des Messerbalkens greift, die bei Überlastung auseinanderfedern und den Kugelzapfen freigeben. Diese ίο Vorrichtung zum Abkuppeln ist einfach herzustellen und kommt bei jeder Überlastung der Maschine mit Sicherheit zur Wirkung.The invention relates to a device on mowing machines for automatic uncoupling the push rod from the cutter bar in the event of malfunctions. The essence of the invention is that the usual ball stud formed on the push rod between two resilient, with bearing sockets equipped steel plates of the cutter bar, which spring apart when overloaded and release the ball stud. This device for uncoupling is easy to manufacture and is sure to take effect whenever the machine is overloaded.

Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt.
Abb. ι ist ein Grundriß eines Messers mit der Abkupplungsvorrichtung.The subject matter of the invention is shown in the drawing, for example.
Fig. Ι is a plan view of a knife with the uncoupling device.

Abb. 2 ist eine Seitenansicht undFig. 2 is a side view and

Abb. 3 ein Querschnitt durch die Schubstange. Fig. 3 is a cross-section through the push rod.

An dem Balken α des in üblicher Weise mit Zähnen c und Aussparungen b versehenen Messers sind zwei winkelförmige, federnde Stahlplatten & angeordnet. Jede der Stahlplatten besitzt die übliche pfannenartige Vertiefung. Diese beiden Vertiefungen umfassen das kugelförmig ausgebildete Ende der Schubstange g. Two angular, resilient steel plates & are arranged on the bar α of the knife, which is provided in the usual way with teeth c and recesses b. Each of the steel plates has the usual pan-like recess. These two depressions encompass the spherical end of the push rod g.

JDie Teile e sind beispielsweise mit Hilfe von Nieten f an dem Messerbalken befestigt.The parts e are fastened to the cutter bar with the aid of rivets f, for example.

Sobald eine Überlastung der Maschine und die Gefahr eines Bruches von Maschinenteilen eintritt, gleitet der Kugelzapfen g der Schubstange aus seinem federnden Lager heraus, wodurch die Kupplung zwischen Schubstange und Messerbalken gelöst ist.As soon as the machine becomes overloaded and there is a risk of machine parts breaking, the ball stud g of the push rod slides out of its resilient bearing, thereby releasing the coupling between the push rod and cutter bar.
