Description
durchsetzenden, als Scherstifl ausgebildeten Bolzen 12 und einer Lasche 15 mit einem Tragrohr 11 in Verbindung, welches zusammen mit einem zur Verbreiterung der Aufhängebasis dienenden Zweigrohr um eine in Fahrtrichtung verlaufende waagerechte Achse b-b' am Schlepper angelenkt ist.penetrating, designed as a Scherstifl bolt 12 and a bracket 15 with a support tube 11 in connection, which is articulated together with a branch pipe serving to widen the suspension base about a horizontal axis bb ' running in the direction of travel on the tractor.
Wie F i g. 1 zeigt, schließt der Tragrahmen 8 mit dem Boden in Richtung zum Schlepper einen veränderlichen Winkel c ein. Die auf die Fahrtrichtung bezogene Neigung des Messerbalkens 1 zum Boden wird durch die relative Lage des Bügels 5 in bezug auf den Tragrahmen 8 bestimmt und kann durch einen mittels eines Schwenkbolzens 22 am Tragrahmen 8 schwenkbar gelagerten Handhebel 21 feststellbar verändert werden. Die Verbindung zwischen Handhebel 21 und Bügel 5 erfolgt über eine Stange 23, die mit ihrem einen Ende über einen Bolzen 28 an dem dem Schwenkbolzen 6 abgelegenen Ende des Bügels 5 angelenkt ist und mit ihrem anderen Ende über einen Bolzen 27 mit dem Handhebel 21 verbunden ist. Die eingestellte Lage des Bügels 5 läßt sich durch einen am Handhebel 21 vorgesehenen Rastbolzen 31 festlegen, der in entsprechende Kerben eines Segments 32 einrastet.Like F i g. 1 shows, the support frame 8 forms a variable angle c with the ground in the direction of the tractor. The inclination of the cutter bar 1 to the ground in relation to the direction of travel is determined by the relative position of the bracket 5 in relation to the support frame 8 and can be changed in a fixed manner by a hand lever 21 pivotably mounted on the support frame 8 by means of a pivot pin 22. The connection between hand lever 21 and bracket 5 takes place via a rod 23, which is hinged at one end via a bolt 28 to the end of bracket 5 remote from pivot pin 6 and at its other end is connected to hand lever 21 via a bolt 27 . The set position of the bracket 5 can be determined by a locking bolt 31 provided on the hand lever 21, which engages in corresponding notches in a segment 32.
Da die Verschwenkung des Bügels 5 um die Achse d-d' erfolgt und diese oberhalb und in der Nähe der Messerbalken-Vorderkante verläuft, bleibt bei jeder Veränderung des Neigungswinkels des Messerbalkens der Bodenabstand der Schnittkante gleich.Since the bracket 5 is pivoted about the axis dd ' and this runs above and in the vicinity of the front edge of the cutter bar, the ground clearance of the cutting edge remains the same with every change in the angle of inclination of the cutter bar.
Um einer durch allmähliche Abnutzung der mechanisch beanspruchten Teile bedingten Abweichung von der rechtwinkligen Lage des Messerbalkens zur Fahrtrichtung, nämlich ein Zurückbleiben des Außenschuhs in bezug auf den Innenschuh, entgegenzuwirken, kann der Tragrahmen 8 um das Tragrohr 11 in Richtung des Pfeiles / verschwenkt und in einerA deviation caused by the gradual wear and tear of the mechanically stressed parts of the perpendicular position of the cutter bar to the direction of travel, namely a lagging behind the Outer shoe with respect to the inner shoe to counteract, the support frame 8 around the support tube 11 pivoted in the direction of the arrow / and in a

The support frame 8 then takes the in F i g. 4 with 8 ', indicated with dashed lines a position, whereby the laterally migrated axis O 1 -O 1 ' again the

The end result the corrective adjustment is that between the cutter bar and the direction of pull a right again Angle is made.
