Description

Die Erfindung betrifft einen Überkopf-Trommelwender mit einer die im Maschinengestell liegend angeordnete Trommel teilweise abdeckenden Führungshaube, mit der mittig zur Trommel angeordnete, keilförmig nach hinten divergierende Ablenkflächen für das von der Trommel mitgenommene Gras, Heu od. dgl. verbunden sind.The invention relates to an overhead drum turner with one that is arranged lying in the machine frame The guide hood partially covering the drum, with the wedge-shaped, arranged in the middle of the drum deflecting surfaces diverging to the rear for the grass, hay carried along by the drum or the like. Are connected.

Bei einem bekannten Trommelwender dieser Art sind die Ablenkflächen von zwei hinter der Trommel befindlichen, gegensinnig schräg nach außen geneigten Prallblechen gebildet, von denen das von der Trommel nach hinten geworfene Heu nach unten abgelenkt und dadurch gleichmäßig auf dem Boden verteilt wird.In a known reel turner of this type, the baffles of two are behind the reel located, inclined in opposite directions obliquely outward Baffles are formed from which the hay thrown backwards by the drum is deflected downwards and is thus evenly distributed on the floor.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, den Überkopf-Trommelwender so auszubilden, daß das von der Trommel mitgenommene Gras, Heu od. dgl. auch zu Schwaden abgelegt werden kann. Diese Aufgabe wird bei einem Überkopf-Trommelwender der geschilderten Art dadurch gelöst, daß die etwa senkrecht zum Boden stehenden Ablenkflächen von einem das Gras, Heu u. dgl. zu Schwaden aufteilenden Gutteiler gebildet sind, der sich an der Innenwandung der Führungshaube entlang und in den Raum zwischen der Führungshaube und der. Trommel erstreckt.In contrast, the invention is based on the object of designing the overhead drum turner in such a way that that the grass, hay or the like carried along by the drum can also be stored in swaths. This object is achieved in an overhead drum turner of the type described in that the deflecting surfaces which are approximately perpendicular to the ground and which divide the grass, hay and the like into swaths Good dividers are formed, which extend along the inner wall of the guide hood and into the space between the guide hood and the. Drum extends.

Infolge dieser Ausbildung und Anordnung der Ablenkflächen wird das von der Trommel mitgenommene Gras oder Heu bereits unterhalb der Führungshaube etwa in Trommelmitte aufgeteilt und dann in zwei getrennten Bahnen um die Trommel geführt, so daß es ohne Schwierigkeiten hinter der Trommel zu zwei nebeneinanderliegenden Schwaden abgelegt werden kann.As a result of this design and arrangement of the deflecting surfaces, that which is carried away by the drum is carried along Grass or hay is already divided and roughly in the middle of the drum underneath the guide hood then passed around the drum in two separate tracks so that it can easily be traced behind the drum The drum can be deposited into two adjacent swaths.

Es ist bei einem Feldhäcksler bekannt, zum Ablegen des Gutes auf dem Boden einen Leitschirm vorzusehen, der an Stelle des normalerweise vorhandenen Blasrohres aufgesetzt werden kann, und der zur Änderung der Lage des durch ihn gebildeten Schwadens verstellbar ist. Eine Aufteilung des Gutes in mehrere Schwaden ist aber mit diesem Leitschirm nicht möglich.It is known in a forage harvester to provide a guide screen for depositing the crop on the ground, which can be put on in place of the normally existing blowpipe, and the for Change in the position of the swath formed by it is adjustable. A division of the property into multiple swaths are not possible with this guide screen.

In Weiterbildung des erfindungsgemäßen Überkopf-Trommelwenders weist der Gutteiler gruppenweise übereinander angeordnete Stäbe auf, die über die rückwärtige Kante der Führungshaube hinaus nach hinten reichen. Diese Stabgruppen führen also das Gras oder Heu in Fortsetzung der unterhalb der Führiingshaube getrennten Bahnen hinter der Haube zu den beiden gewünschten Schwaden zusammen. Dadurch können genau begrenzte Schwaden gezogen werden.In a further development of the overhead drum turner according to the invention, the material divider has in groups one on top of the other on bars that extend beyond the rear edge of the guide hood reach backwards. These groups of rods thus lead the grass or hay in continuation of the below the Leading hood separate lanes behind the hood to form the two desired swaths. This means that precisely delimited swaths can be drawn.

Nach einem weiteren Merkmal der Erfindung erstreckt sich der Gutteiler mit seinem vorderen Ende bis vor die Vertikalebene, in der die Drehachse der Trommel liegt. Das Gras oder Heu wird dadurch schon während seiner Aufwärtsbewegung auf getrennte Bahnen geführt.According to a further feature of the invention, the material divider extends with its front end up to the vertical plane in which the axis of rotation of the drum lies. This will make the grass or hay already guided on separate tracks during its upward movement.

Damit der Überkopf-Trommelwender auch für das übliche Graszetten eingesetzt werden kann, sind die die schwadenbildenden Stabgruppen abnehmbar am Maschinengestell befestigt. Zweckmäßig sind hierfür die Stäl)c in einer gemeinsamen Halterung gelagert, die abnehmbar an der rückwärtigen Kante der Fiihrungshaube befestigt ist. Die gemeinsame Befestigung und Abnahme der Stäbe ist dadurch besonders einfach. So that the overhead drum turner can also be used for normal grass tedding, the the swath-forming rod groups are detachably attached to the machine frame. Useful for this are the Stäl) c stored in a common holder, which is removable on the rear edge of the guide hood is attached. The joint attachment and removal of the rods is particularly easy.

Hui einer Ausführungsfonii des erfindungsgemäf.ieii Überkopf-Trommelwenders ist vorgesehen, daß das vordere Ende des Gutteilers mit der Drehachse der Trommel in gleicher Höhe liegt. Dadurch wird das aufgenommene Gras oder Heu bereits kurz nach Beginn der Mitnahme aufgeteilt und die Zusammenführung zu Schwaden weiter erleichtert.Hui an embodiment of the inventivef.ieii Overhead drum turner is provided that the front end of the Gutteiler with the axis of rotation of the Drum is at the same height. This means that the grass or hay that has been picked up is already shortly after Start of taking split and merging to swaths further facilitated.

Bei einer weiteren Ausfühningsform des erfindungsgemäßen Trommelwenders weist der über die rückwärtige Kante der Führungshaube hinausragende ίο Gutteiler zwei Platten auf, die an der Innenwandung der Führungshaube nach hinten divergierend befestigt sind. Infolge dieser Anordnung werden die Führungsbahnen für das Heu unterhalb der Führungshaube zunehmend schmaler, so daß das Zusammenfassen des Gutes zu Schwaden bereits in dem Raum zwischen der Führungshaube und der Trommel eingeleitet wird. Dabei ist es zweckmäßig, wenn sich die divergierenden Flächen des Gutteilers oberhalb der Trommel befinden, damit das bereits aufgeteilte Gras oder Heu beim Verlassen der Trommel außer der nach unten gerichteten auch schon eine seitwärts gerichtete Bewegungskomponente erhält. Darum soll - _;1!'die Trommel bei dieser Ausführungsform von der Führungshaube mit einem Zentriwinkel von 90° um-.. 25, geben sein, so daß sich die Führungshaube auch oberhalb der Trommel erstreckt.In a further embodiment of the drum turner according to the invention, the material divider projecting beyond the rear edge of the guide hood has two plates which are attached to the inner wall of the guide hood so as to diverge towards the rear. As a result of this arrangement, the guide tracks for the hay below the guide hood become increasingly narrow, so that the gathering of the material into swaths is already initiated in the space between the guide hood and the drum. It is useful if the diverging surfaces of the crop divider are located above the drum so that the grass or hay that has already been divided has a sideways movement component when it leaves the drum, in addition to the downward movement. That is why - _{; 1!} 'In this embodiment, the drum must be surrounded by the guide hood with a central angle of 90 °, so that the guide hood also extends above the drum.
