Description
Den Gegenstand der Erfindung bildet eine Andrückfeder mit einer ihren Hub begrenzenden Pratze für Mähmaschinenmesser, die zum elastischen Andrücken des Mähmaschinenmessers an den das Messer in bekannter Weise führenden Fingerbalken dient.The subject matter of the invention is a pressure spring with a stroke limiting its stroke Claw for mower knife, which is used for elastic pressing of the mower knife serves on the finger bar leading the knife in a known manner.
Bei bekannten Einrichtungen ist die Andrückfeder selbst an einer starren Pratze befestigt, welche die Andrückfeder teilweise ίο kapselartig umschließt und den etwaigen Hub des Messers in unelastischer Weise begrenzt, was u. a. zur Folge hat, daß sich die Andrückfeder durch Steine, Sand, Schnittgut u. dgl. an ihrer Pratze verklemmt und die Pratze selbst starkem Verschleiß ausgesetzt ist.In known devices, the pressure spring itself is attached to a rigid claw, which partially encloses the pressure spring ίο like a capsule and the possible stroke of the knife is limited in an inelastic manner, which inter alia. has the consequence that the pressure spring jammed by stones, sand, clippings and the like on their claw and the claw itself is exposed to heavy wear.
Demgegenüber wird gemäß der Erfindung auch die Stützpratze selbst nachgiebig angebracht, wodurch jene Nachteile vermieden werden. Die Neuerung ist in einem Ausführungsbeispiel in der Zeichnung dargestellt. In contrast, according to the invention, the support claw itself is attached flexibly, thereby avoiding those disadvantages. The innovation is in one embodiment shown in the drawing.
Abb. ι zeigt die Andrückfeder mit bruchstückweise dargestelltem Mähmaschinenmesser und Fingerbalken in Draufsicht.Fig. Ι shows the pressure spring with fragments shown mower knife and finger bar in plan view.
Abb. 2 ist ein Schnitt nach Linie A-B in Abb. i.Fig. 2 is a section along line AB in Fig. I.
Die Andrückvorrichtung weist einen Block α auf, der durch die zur Befestigung der Finger b am Fingerbalken c dienenden Schrauben d am Balken befestigt ist und an dem eine starke Blattfeder e durch Niete f befestigt ist. Diese Blattfeder e trägt am vorderen, frei tragenden Ende eine an ihr mittelsThe pressing device has a block α which is fastened to the bar by the screws d used to fasten the fingers b to the finger bar c and to which a strong leaf spring e is fastened by rivets f. This leaf spring e carries at the front, cantilevered end one on her means
ίο Niete g befestigte Druckfeder h und eine die Bewegung dieser Druckfeder h elastisch begrenzende Pratze i. An dem freien Ende der Druckfeder h ist eine Andrückplatte k durch Niete I befestigt, die beispielsweise aus in eine Metallfassung fe eingepreßter Fiber m bestehen kann und gegen das Messer η elastisch gedrückt wird, welches in an dem Fingerbalken c und den Fingern b vorgesehenen Führungsteilen o, p geführt wird. Zur Regelung des von der Druckfeder h und mithin der Andrückplatte k auf das Messer η auszuübenden elastischen Druckes ist an dem einen Ende der Pratze j eine in ihr verstellbare Stellschraube q vorgesehen.ίο rivet g attached compression spring h and a claw i elastically limiting the movement of this compression spring h. At the free end of the compression spring h , a pressure plate k is attached by rivets I , which can consist, for example, of fiber m pressed into a metal frame fe and is pressed elastically against the knife η , which in guide parts o provided on the finger bar c and the fingers b , p is performed. To regulate the elastic pressure to be exerted on the knife η by the compression spring h and consequently the pressure plate k, an adjustable screw q is provided at one end of the claw j.
