Description

ilLtel: Selbstätiger Federspanner für die SchlepperhydraulikilLtel: Automatic spring tensioner for the tractor hydraulics

Anwendungs-,Jehiet: Die Erfindung stellt ein 7Jusstzgerät für Arbeitsgerste angebaut an der Schlepperfront oder Heckhydraulik, insbesondere für Kreiselmäher im Schlepperfrontanbau;dar.Application, Jehiet: The invention represents a 7Jusszgerät for working barley mounted on the tractor front or rear hydraulics, especially for rotary mowers in the front of the tractor;

Stand der technik: Die bisher im landwirtschaftlichen Einsatz befindlichen Frontmähwerke sind mit Federn ausgestattet, die beim Mähen die Schleppervorderachse belasten und den Bodendruck des Kreiselmähwerkes verringern.State of the art: those previously in agricultural use Front mowers are equipped with springs that hold the tractor's front axle when mowing load and reduce the ground pressure of the rotary mower.

Diese Federn, müssen nach dem Ankuppeln des Mähwerkes an die Schlepperhydraulik, von Hand an der Schlepperfront eingehängt werden. After coupling the mower to the tractor hydraulics, these springs must be hung by hand on the tractor front.

Aufgabe: Die Erfindung hat die Aufgabe für in Verbindung mit dem Einphasen-Schnellkuppler (Deutz-Hitch) und der selbstätigen elenkwellenkupplung Weidle Pat.Nr.Task: The invention has the task for in connection with the single-phase quick coupler (Deutz-Hitch) and the self-acting universal joint shaft coupling Weidle Pat.

31 94 706,7 das Arbeitsgerät anzukuppeln und die Funktion der oben beschriebenen Federn herzustellen. 31 94 706.7 to couple the implement and the function of the above produce described springs.

Lösung: Die Aufgabe wird dadurch gelöst, in dem man an beiden Unterlenkern der Hydraulik winkelförmige Hebel(?) drehbar lagert, wobei an einem Ende des Hebels eine Seilrolle(2) angebracht wird. Die Federn werden nun mit einem Ende wie bisher an der Schlepperfront eingehängt. Das andere Ende, das bisher mit dem Mähwerkrahmen verbunden war, wird nun an einem Seil(4) befestigt. Dieses Seil(4) wird nun über die Seilrolle(2) des winkelförmigen Hebels(1) parallel zu den Hydraulikunterlenkern, zurück zur Schlepperfront geführt und dort befestigt.Solution: The task is solved by pulling on both lower links the hydraulic angular lever (?) rotatably supports, with one end of the lever a pulley (2) is attached. The springs will now have one end as before attached to the front of the tractor. The other end, the one so far with the mower frame was connected, is now attached to a rope (4). This rope (4) is now over the pulley (2) of the angled lever (1) parallel to the hydraulic lower links, led back to the front of the tractor and fastened there.

Beim Ankuppeln des Mähwerkes werden nun die noch nicht beschriebenen Hebelenden(3) vom Mähwerkrahmen (eventuell auch zusätzlich angebrachten Hilfsrahmen) nach unten gedrückt. Dadurch verändern die Hebelenden mitden Seilrollen(2) ihre Stellung Richtung Mähwerk und die Federn werden gespannt. When coupling the mower, the not yet described Lever ends (3) from the mower frame (possibly also an additional subframe) pressed down. As a result, the lever ends with the rope pulleys (2) change theirs Position towards the mower and the springs are tensioned.

Zusätzlich könnte ein Seilspanner(5) im Seil (4) eingebaut werden, mit dem die Federspannung stufenlos eingestellt werden kann. In addition, a rope tensioner (5) could be installed in the rope (4), with which the spring tension can be continuously adjusted.

Erzielbare Vorteile: Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß der Schlepperführer beim Ankuppeln eines Arbeitsgerätes (in dem Fall ein Kreiselmäher) seinen ahrersitz nicht mehr verlassen muß.Ein weiterer Vorteil besteht darin, daß die Federspannung stufenlos eingestellt werden kann.Achievable Advantages: The advantages achieved with the invention exist in particular that the tractor driver when coupling a working device (in this case a rotary mower) no longer has to leave his driver's seat The advantage is that the spring tension can be continuously adjusted.

Beschreibung eines Ausführungsbeispieles: Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt.Description of an exemplary embodiment: An exemplary embodiment the invention is shown schematically in the drawings.

Es zeigen: Fig.1 Die Seitenansicht der Erfindung während des Kupplungsvorgangese Fig.2 Die Seitenansicht der Erfindung nach Beendigung des Ankuppelns, also im betriebsbereiten Zustand. They show: FIG. 1 the side view of the invention during the coupling process Fig.2 The side view of the invention after the end of the coupling, that is, in the operational state State.

Die einzelnen Teile der Erfindung sind in den 7.eichnungen wie folgt gekenzeichnet: (1) winkelförmiger hebel, (2) Seilrolle, (3) das Hebelende am Mähwerkrahmen, (4) Seil (5) Seilspanner.The individual parts of the invention are shown in the 7th drawings as follows Marked: (1) angled lever, (2) pulley, (3) the end of the lever on the mower frame, (4) Rope (5) Rope tensioner.
