Gegenstand der Erfindung ist eine Ausklinkvorrichtung an starren Grubberzinken zum Xachgeben bei ungewöhnlichen Hindernissen.The subject of the invention is a notching device on rigid cultivator tines for yielding in the case of unusual obstacles. Die bekannten starren Zinken haben den Vorteil tier unverändert günstigen Schnittwinkelstellung der Scharen bei der Arbeit. Sie können jedoch bei Schlepperzug in steinigem Boden nicht verwendet werden, da kein Schutz gegen Bruch und Verbiegen des Zinkens sowie auch des Rahmens vorhanden ist.The well-known rigid tines have the advantage tier unchanged favorable cutting angle position of the multitudes at work. However, they cannot be used when hauling a tractor in stony ground as there is no protection against breakage and bending of the tine and the frame. ίο Die bekannten federnden starren Zinken sowie die in sich federnden Zinken verlieren bei schwerer Arbeit die günstige Schnittwinkelstellung der Scharen (schwerer Kopfgang).ίο The well-known resilient rigid tines as well the resilient prongs lose the favorable cutting angle position of the during hard work Flocks (heavy head walk). Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Ks zeigt Fig. ι Seitenansicht in Arbeitsstellung,The subject of the invention is in the drawing shown in one embodiment. Ks shows Fig. Ι side view in the working position, Fig. Fig. 2 Seitenansicht in ausgeklinkter Stellung.2 Side view in the notched position. Bei dem Erfindungsgegenstand wird der um den Holzen α drehbare starre Zinken b durch die Geleitkstütze C1 in Verbindung mit dem liebele», welcher im Punkt / drehbar gelagert ist, gegen die Rückstellfeder e abgestützt und in Arbeitsstellung gehalten. Die Gelenkstütze ist bei i am Zinken b und bei k am Hebel C2 angelenkt. In dieser Stellung liegt die Gelenkstütze C1 in Verbindung mit dem Hebel c, und dem Drehpunkt / nahe an der Geraden bzw. Totpunktstellung, wodurch ein außerordentlich hoher Ausklinkwiderstand erreicht wird. Zur genauen Einstellung dieser Stellung ist die Stellschraube d oder ein sonstiger stellbarer Anschlag vorgesehen.In the subject matter of the invention, the rigid tine b rotatable about the wood α is supported against the return spring e and held in the working position by the guide support C 1 in connection with the love element, which is rotatably supported at point /. The joint support is hinged at i on prongs b and at k on lever C 2. In this position, the joint support C 1 is in connection with the lever c, and the pivot point / close to the straight line or dead center position, whereby an extremely high release resistance is achieved. Adjustment screw d or some other adjustable stop is provided for precise adjustment of this position. Beim Auftreten außergewöhnlicher Widerstände gibt die Gelenkstütze C1 nach und überträgt den Druck über den im Punkt /' drehbar gelagerten Hebel c, auf die Druckfeder c. Dadurch spannt sich die Druckfeder c und drückt den Zinken/; nach LTberwiuidung des Widerstandes in die Arbeitsstellung zurück.If exceptional resistance occurs, the joint support C 1 gives way and transfers the pressure via the lever c, which is rotatably mounted at point / ', to the compression spring c. This tensions the compression spring c and presses the prongs /; after L T overcoming the resistance back to the working position. Hierdurch wird sowohl der Rahmen als auch der Zinken gegen Verbiegen oder Brechen geschützt.This protects both the frame and the prongs from bending or breaking. Da der Zinkendrehpunkt im Bolzen α und die Scharspitze if senkrecht übereinanderliegen. kann sich der Zinken b nur nach oben bewegen und lost sich leicht vom Hindernis.Because the tine pivot point in the bolt α and the share tip if are perpendicular to one another. the prong b can only move upwards and easily detaches from the obstacle.
