Description

Es sind Aushebevorrichtungen für Anbaupflüge und Anbaugeräte bekannt, bei denen eine das Gerät aushebende und tragende Kette auf eine am Schlepper angebrachte Trommel od. dgl. aufgewickelt wird, um das Gerät auszuheben. Solche Trommeln werden beispielsweise durch mittels Handhebel ■ betätigte Klinkengesperre in Drehung versetzt. Die bisherigen Ausführungen dieser Art zeigen den folgenden Mangel: Während der ArbeitThere are lifting devices for plows and attachments are known in which the The lifting and carrying chain of the device is wound onto a drum or the like attached to the tractor to dig out the device. Such drums are for example by means Hand lever ■ actuated ratchet lock set in rotation. The previous statements of this type show the following shortcoming: While working

ίο muß sich das Gerät hinter dem Schlepper auf und ab frei bewegen können. Die Kette muß also einen Freigang 'haben, d. h. während der Arbeit durchhängen. Beim Ausheben am Feldende muß dann zuerst der Handhebel so lange hin und her bewegt werden, bis die Kette sich spannt, und erst dann beginnt das eigentliche Ausheben. Dadurch entsteht ein Zeitverlust, der durch die Einrichtung gemäß der Erfindung beseitigt wird. Erfindungsgemäß wird die Kette in der Arbeitsstellung des Gerätes ständig unter einer gewissen Spannung gehalten. Das wird durch eine Feder erreicht, die an einem Anschlaghebel angreift, welcher an einem an der Kettentrommel befindlichen Anschlag anliegt und daher beim Abwickeln der Kette von der Trommel mitgenommen wird, wobei die Feder gespannt wird. Diese Spannung überträgt sich auf die Kette, die dadurch so· straff genug ist, um ein sofortiges Anheben des Gerätes beim Beginn der Handhebelbewegung zu ermögliehen, andererseits aber das Gerät nicht in unerwünschtem Maße entlastet. Durch diese Erfindung wird der Wert bzw. die Brauchbarkeit aller derartigen Aushebevorrichtuhgen für Anbaugeräte entscheidend günstig beeinflußt.ίο the device must be behind the tractor on and from can move freely. The chain must therefore have a clearance, i.e. H. sag while working. When digging out at the end of the field, the hand lever must first be moved back and forth for such a long time until the chain is taut, and only then does the actual excavation begin. This creates a loss of time which is eliminated by the device according to the invention. According to the invention the chain is constantly under a certain tension in the working position of the device held. This is achieved by a spring that acts on a stop lever, which on a stop located on the chain drum rests and therefore when unwinding the Chain is taken along by the drum, whereby the spring is tensioned. This tension is transferred to the chain, which is thus tight enough to allow the device to be lifted immediately to enable at the beginning of the hand lever movement, but on the other hand not the device in undesirable Dimensions relieved. This invention establishes the value or utility of all such Aushebervorrichtuhgen for attachments decisively influenced favorably.

Ein Ausführungsheispiel, durch welches der Erfindungsgedanke verwirklicht ist, wird im folgenden dargestellt und beschrieben.An exemplary embodiment through which the concept of the invention is implemented is shown below shown and described.

Abb. ι zeigt die Handaushebevorrichtung gemäß der Erfindung in der Seitenansicht;Fig. Ι shows the hand lifting device according to the invention in a side view;

Abb. 2 zeigt dieselbe Einrichtung von hinten gesehen.Fig. 2 shows the same device seen from behind.

Auf die Kettentrommel 1 wird die Aushebe- und Tragkette 2 zum Ausheben des Gerätes mit Hilfe des Doppelklinkengesperres 3, 4, S aufgewickelt. Der auf der Trommelachse frei beweglich gelagerte Anschlaghebel 7 wirkt durch, die Kraft der Feder 6 über den an der Trommel' 1 befindlichen Anschlag 8 im gleichen Drehsinn auf die letztere, bis er seine Endlage erreicht hat und die Trommel 1 ihm im Verlauf ihrer Weiterdrehung vorauseilt, bis die Aushebestellung des Gerätes erreicht ist. In dieser Lage bleibt die Kettentrommel ι durch die Klinke 3, 4 verriegelt bis zum Zwecke des Herablassens des Gerätes der Hebel S nach hinten geschwenkt und dadurch beide Klinken 3,-4 außer Eingriff gebracht werden. Die Kettentrommel 1 dreht sich dann durch den Zug der Tragkette 2, bis ihr Anschlag 8 mit dem Anschlaghebel 7 in Berührung kömmt und diesen so lange mitnimmt, bis das Gerät in seiner Arbeitslage angekommen ist.The lifting and carrying chain 2 is attached to the chain drum 1 for lifting the device With the help of the double ratchet mechanism 3, 4, S wound up. The freely movable on the drum axis The mounted stop lever 7 acts through the force of the spring 6 via that located on the drum '1 Stop 8 in the same direction of rotation on the latter until it has reached its end position and the Drum 1 runs ahead of it in the course of its further rotation until the device is lifted out is reached. In this position, the chain drum remains locked by the pawl 3, 4 until For the purpose of lowering the device, the lever S is pivoted backwards and thereby both Pawls 3, -4 are disengaged. The chain drum 1 then rotates through the train the suspension chain 2 until its stop 8 comes into contact with the stop lever 7 and this so takes a long time until the device has reached its working position.

Während der nun folgenden Arbeitsperiode steht die Trommel 1 auf dem Wege über ihren Anschlag 8 und den Anschlaghebel 7 ständig unter Wirkung der Feder 6, was eine ständige Spannung der Tragkette 2 zur Folge hat. Da nun das Gerät während der Arbeit ununterbrochen gegenüber dem Schlepper aufwärts und abwärts schwingt, wird die Trommel 1 durch den Zug der Feder 6 sich ebenfalls ununterbrochen bewegen, die Kette 2 70-wird aber stets gespannt bleiben. Werden nun zum Zwecke des Aushebens des Gerätes durch Betätigung des Hebels 5 die Klinken 3, 4 in Eingriff gebracht, so wird bereits der erste Hub des Hebels 5 zum Ausheben des Gerätes ausgewertet. Leerhübe, die lediglich zum Anspannen der Tragkette 2 dienen, sind nicht erforderlich.During the working period that now follows, the drum 1 is on the way over its stop 8 and the stop lever 7 constantly under the action of the spring 6, which is a constant tension the carrying chain 2 has the consequence. Since now the device while working uninterruptedly opposite the tractor swings up and down, the drum 1 is pulled by the tension of the spring 6 also move uninterruptedly, but the chain will always remain taut. Now become the For the purpose of lifting out the device, the pawls 3, 4 are brought into engagement by actuating the lever 5, the first stroke of the lever 5 for lifting the device is already evaluated. Idle strokes, which are only used to tension the support chain 2 are not required.
