Description
Die Aufgabe wird bei einem Kreiselmähwerk der ein-
F i g. 4 einen Schnitt nach IV-IV in F i g. 1. vergrößert
Die Mähmaschine hat ein Anbaugestell I. einen Tragarm 2 und ein Kreiselmähwerk mit einem Querträger 3. an dem Mähkreisel 4, 5, 6 und 7 gelagert sind. Das Gestell 1 besteht aus einem Anbaubock, der an die heckseitige Dreipunkt-Hebevorrichtung eines die Maschine ziehenden Schleppers angeschlossen ist. An einem Schenkel des Anbaubocks ist rückseitig eine Gabel befestigt, in der das eine Gabelstück einer Doppelgabel mit einem schräg nach vorne geneigten Steckbol/en schwenkbar angeordnet ist. Um die horizontale Achse der Doppelgabel ist der seitwärts und nach unten gerichtete Tragarm 2 schwenkbar, der außerdem bei Auflaufen des Mähwerks auf Hindernisse um den Verbindungsbolzen der beiden Gabeln nach hinten schwenken kann, wobei eine Überlastungskupplung gelöst wird, die den Tragarm 2 mit dem Gestell 1 verbindet. Ein Gestänge mit Kettenzug und Bedienungshebel dient zum Aus-
Das Übersetzungsverhältnis der Getriebe ist so gewählt, daß die Mähkreisel bei einer Zapfwellendrehzahl von 540 U/min mit einer Drehzahl von mehr als 3500 U/ min, beispielsweise mit etwa 4000 U/min rotieren, so daß sich bei einem Kreiseldurchmesser zwischen 25 cm und 50 cm Umfangsgeschwindigkeiten der Messer von mindestens 85 m/sec.beispielsweise 90 m/sec oder mehr ergeben. Im Ausführungsbeispiel beträgt der Kreiseldurchmesser 43 cm und damit die Gesamtarbeitsbreite des V.ähwerks, bei der vorgesehenen Überlappung der Messerbahnen, etwa 160 cm.
