Description

Die vorliegende Erfindung hat eine Verbesserung an jenen Eggen zum Gegenstand, bei denen zum Zwecke der Reinigung der die Eggenzinken tragende Rahmen durch Ketten an eine Kurbelwelle angeschlossen ist und zeitweise angehoben werden kann.The present invention aims to improve those harrows in which for the purpose of cleaning the frame carrying the harrow tines by chains on a crankshaft is connected and can be temporarily raised.

Gegenüber den bekannten Einrichtungen dieser Art, bei welchen jedes einzelne Anheben durch einen Stellhebel eingeleitet werden muß, ίο wird durch die vorliegende Erfindung bezweckt, die Bedienung wesentlich zu vereinfachen und die Wirkung der Egge der jeweiligen Bodenbeschaffenheit weitgehendst anzupassen.Compared to the known devices of this type, in which each individual lifting must be initiated by an adjusting lever, ίο is intended by the present invention, to simplify the operation significantly and the effect of the harrow of the respective soil conditions adapt as much as possible.

Dies wird dadurch erreicht, daß die Kurbelwelle mittels emer von Hand verstellbaren Kupplung mit den Laufrädern derart auf Antrieb zu verbinden ist, daß je nach Bedarf der Eggenrahmen mehr oder weniger oft nacheinander ausgehoben werden kann, ohne deshalb die Kupplung wiederholt in Tätigkeit setzen zu müssen.This is achieved in that the crankshaft by means of a manually adjustable clutch is to be connected to the drive with the wheels in such a way that the harrow frame as required can be excavated more or less often one after the other without having to repeatedly activate the clutch have to.

Eine solche Egge mit zum Zwecke der Reinigung zeitweise anhebbarem, durch Kette an eine Kurbelwelle angeschlossenem Rahmen ist durch die Abb. 1 bis 3 der Zeichnung in einer Ausführungsform dargestellt, wobei Abb. 1 eine Seitenansicht, Abb. 2 die Draufsicht und Abb. 3 einen in vergrößertem Maßstabe gezeichneten Schnitt durch die Kupplung erkennen lassen. An dem die Laufräder tragenden Gestell a ist eine durchgehende Welle e gelagert, die mit zwei abgekröpften Kurbeln versehen ist. Die Kurbelzapfenlager f sind durch die Ketten fg, fk, fi, fk mit dem Rahmen der Egge verbunden, so daß in bekannter Weise beim Kreisen der Kurbelwelle, die von der vorderen Laufradachse b durch die Kettenräder c, d und eine sie verbindende Kette Antrieb erhält, die Eggen be; jeder Umdrehung der Kurbelwelle einmal ausgehoben und wieder gesenkt werden. Um das Heben und Senken der Egge weitgehendst der Bodenbeschaffenheit anzupassen, dabei aber gleichwohl die Bedienung wesentlich zu vereinfachen, ist das Kettenrad d lose auf der Kurbelwelle e drehbar und mit der einen Hälfte einer Mitnehmerkupplung versehen, deren andere Hälfte η mittels Nut und Feder verschiebbar, aber gegen Drehung gesichert auf der Kurbelwelle befestigt ist. Die in eine Ringnut der Kupplungshälfte η eingreifende Gabel bildet den kurzen Arm je eines an der Querleiste des Gestelles α gelagerten Winkelhebels in, deren andere Arme quer zum Gestell α verlaufen und zu einer an der Zwischenleiste achsial verschiebbaren Stellstange I derart führen, daß durch Verschieben der letzteren die Kupplung ein- oder ausgerückt und damit die Kurbelwelle angetrieben oder stillgesetzt werden kann. Solange die Kupplung eingerückt ist, tritt bei jeder Umdrehung der Kurbelwelle ein Ausheben der Eggenrahmen ein, während die Egge dauernd auf dem Boden schleift, wenn die Mitnehmerkupplung ausgerückt ist.Such a harrow with a frame connected by chain to a crankshaft and temporarily liftable for the purpose of cleaning is shown in one embodiment in Figs. 1 to 3 of the drawing, Fig. 1 being a side view, Fig. 2 being a plan view and Fig. 3 show the enlarged section through the coupling. A continuous shaft e , which is provided with two cranked cranks, is mounted on the frame a carrying the running wheels. The crank pin bearings f are connected to the frame of the harrow by the chains fg, fk, fi, fk , so that in a known manner when the crankshaft circling, which is driven from the front wheel axle b through the sprockets c, d and a chain connecting them who have harrows ; can be raised and lowered once every revolution of the crankshaft. In order to adapt the lifting and lowering of the harrow as much as possible to the nature of the soil, but at the same time to simplify operation considerably, the chain wheel d can be loosely rotated on the crankshaft e and is provided with one half of a driver coupling, the other half η being displaceable by means of a tongue and groove, but secured against rotation on the crankshaft. The engaging fork η in an annular groove of the coupling half forms the short arm one each on the cross bar of the frame α mounted angle lever, the other arms transversely α extend to the frame and lead to an axially displaceable on the intermediate tray positioning rod I such that by displacing the the latter the clutch engaged or disengaged and thus the crankshaft can be driven or stopped. As long as the clutch is engaged, the harrow frame is lifted with every revolution of the crankshaft, while the harrow is continuously dragging on the ground when the driving clutch is disengaged.
