Die Erfindung betrifft eine Schnellkupplung für an die Lenker der Dreipunktankopplungsvorrichrung eines Schleppers anzukuppelnde landwirtschaftliche Geräte.The invention relates to a quick coupling for the handlebars of the three-point coupling device Agricultural implements to be coupled to a tractor.
Es sind bereits derartige Schnellkupplungen bekannt, die aus zwei Zwischenrahmen bestehen, von denen der eine an die Dreipunktlenker des Schleppers und der andere an das Gerät anschließbar ist. Der schlepperseitige Rahmen wird zur Ankupplung des Gerätes an den Schlepper durch Anheben mittels des Krafthebers des Schleppers mit dem geräteseitigen Rahmen in Eingriff gebracht.There are already such quick couplings known, which consist of two intermediate frames of one of which can be connected to the three-point linkage of the tractor and the other to the device. The frame on the tractor side is used to connect the device to the tractor by lifting it up of the power lift of the tractor brought into engagement with the device-side frame.
Bei einigen dieser Schnellkupplungen wird ein schlepperseitiger dreieckförmiger Rahmen zwecks Einkuppeins von unten her in den ihn von oben her überfassenden geräteseitigen dreieckförmigen Rahmen beim Anheben eingeschoben. Die Rahmen werden dann miteinander verriegelt.With some of these quick-release couplings, a tractor-side triangular frame is used for the purpose of Einkuppeins from below into the device-side triangular frame that encompasses it from above pushed in when lifting. The frames are then locked together.
Obwohl hierbei ein Kuppeln der Rahmen auch dann möglich ist, wenn diese um eine in Fahrtrichtung liegende Achse gegeneinander verdreht sind, so ist hierbei doch für das sichere Einkuppeln Voraussetzung, daß die Rahmenebenen keine wesentliche Winkelabweichung zueinander aufweisen, d.h.Although the frame can also be coupled if it is one in the direction of travel axis are twisted against each other, it is a prerequisite for safe coupling, that the frame planes have no significant angular deviation from one another, i.e.

The frame suspension point may extend in the event of a greater twist Although menebenen are at an angle to each other, the frame against each other a centering of the frame must not, however, be made practically impossible in order to be the same in the direction of travel, since then only lying axes are substantially rotated against each other 35 those lying in the vicinity of the suspension point because then the lower parts of the frames do not edge the pyramid flanks with the other Rahin the men required for the mutual locking come into engagement and this to the Location.
