Description

Gegenstand der Erfindung ist ein. Schneidwerk für Mähmaschinen mit Fingern gleicher Teilung und gruppenweise schneidenden trapezförmigen Messerklingen. Die bekannten derartigen Schneidwerke, bei denen die Messerklingen eine anderie Teilung haben als die Finger, haben den Nachteil, daß sie ungleichmäßig mähen und das gesteckte Ziel, die Mähmaschine zu entlasten, nicht erreichen. Diese Nachteile sollen gemäß der Erfindung dadurch beseitigt werden, daß bei Schneidwerken mit Fingern gleicher Teilung, d.h. mit einem handelsüblichen Fingerbalken, an der Messerschiene zu beiden Seiten einer mittleren, gleichschenkligen trapezförmigen Messerklinge miteinander abwechselnde, ungleichschenklige trapezförmige Messerklingen angeordnet sind, die Schneidkanten von verschiedener Länge und eine Grundlinie von verschiedener Breite haben. Die längere Schneidkante der ungleichschenkligen trapezförmigen Messerklingen kann der mittleren, gleichschenkligen Klinge zugekehrt seiri.The invention is a. Cutting unit for mowers with fingers the same Division and group-cutting trapezoidal knife blades. The known such cutting units in which the knife blades have a different pitch than the Fingers have the disadvantage that they mow unevenly and the set goal, the mower to relieve, not reach. These disadvantages are intended to be achieved according to the invention This eliminates the problem that with cutting units with fingers of the same pitch, i.e. with a commercially available finger bar, on the Knife rail on both sides of a central, isosceles trapezoidal knife blade alternating, unequal-sided trapezoidal knife blades arranged the cutting edges are of different lengths and a base line of different Have width. The longer cutting edge of the unequal-sided trapezoidal Knife blades can be turned towards the middle, isosceles blade.

Eine Ausführungsform der Erfindung ist auf der Zeichnung veranschaulicht. Die Abb. ι und 3 zeigen einen waagerechten Schnitt durch einen Teil des Schneidwerkes mit gemäß der Erfindung angeordneten Mes-"serklingen in zwei verschiedenen Stellungen. In der Abb. 2 ist ein Teil der Messerschiene des Schneidwerkes mit den Messerklingen im Grundriß dargestellt, und die Abb. 4 zeigt die beiden bei dem Schneidwerk verwendeten, miteinander abwechselnden Messerklingen im Grundriß.An embodiment of the invention is illustrated in the drawing. the Fig. Ι and 3 show a horizontal section through part of the cutting unit with knife blades arranged according to the invention in two different positions. In Fig. 2 is part of the knife rail of the cutting unit with the knife blades shown in plan, and Fig. 4 shows the two used in the cutter, alternating knife blades in plan.

An der Messerschiene 1 des Schneidwerkes sind die trapezförmigen Messerklingen 2, S und 6 in bekannter Weise durch Nieten :8 o. dgl. befestigt. Die Messerklinge 2 liegt in der Mitte der Messerschiene und hat gleich lange Schneidkanten. Die Messerklingen 5 und 6, die zu beiden Seiten der Messerklinge 2 angeordnet sind und miteinander abwechseln, sind ungleichschenklig, haben eine Grundlinie von verschiedener Breite sowie dieselbe Höhe wie die mittlere Klinge. Der Fingerbalken 3 hat Finger 4 mit üblicher Teilung.The trapezoidal knife blades 2, S and 6 are fastened to the knife rail 1 of the cutting unit in a known manner by rivets : 8 or the like. The knife blade 2 lies in the middle of the knife rail and has cutting edges of the same length. The knife blades 5 and 6, which are arranged on both sides of the knife blade 2 and alternate with one another, are unequal-sided, have a base line of different widths and the same height as the middle blade. The finger bar 3 has fingers 4 with the usual division.

Bei der dargestellten Ausführungsform der Erfindung sind zu beiden Seiten der mittleren, gleichschenkligen Messerklinge 2 die ungleichschenkligen Messerklingen 5 mit breite-' rer Grundlinie angeordnet und die längere Schneidkante dieser ungleichschenkligen Messerklingen ist der mittleren Messerklinge zugekehrt. In the illustrated embodiment of the invention are on both sides of the middle, isosceles knife blade 2 the unequal knife blades 5 with wide- ' rer baseline and the longer cutting edge of these unequal knife blades is facing the middle knife blade.

Die Abb. 3 zeigt die mittlere Stellung der Messerklingen im Schneidwerk während des Schnittes. Die Bewegungsumkehr der Klingen erfolgt, wenn die mit 7 bezeichnete Stelle der Messerklingen, d.h. die Mitte der kleineren Grundlinie der Klingen, etwa in der Achse der Finger liegt.Fig. 3 shows the middle position of the knife blades in the cutting unit during the Cut. The movement of the blades is reversed when the point marked 7 of the knife blades, i.e. the center of the smaller base line of the blades, roughly in the axis the finger lies.

Während jedes Hubes der Messerschiene schneiden deren Klingen in der Reihenfolge a, b, c und d. During each stroke of the knife rail, its blades cut in the order a, b, c and d.

Neben der mittleren Messerklinge 2 der Messerschiene können auch zwei Klingen mit schmalerer, statt Klingen mit breiterer Grundlinie angeordnet sein.In addition to the middle knife blade 2 of the knife rail, two blades can also be used be arranged narrower, instead of blades with a wider base line.
