Abstract
Description
Die Erfindung bezieht sich auf einen Pflückvorsatz für ein Erntegerät gemäß dem Oberbegriff des Haupt anspruches.The invention relates to a header for a harvester according to the preamble of the main claim.
Aus der EP-91 635 B1 ist ein Erntegerät bekannt, bei welchem als Gegenhalter ein wannenförmig gebogenes Blech eingesetzt wird, wobei diese Teilummantelung als Leitblech für die von der Walze erfaßten Stengel dient. Hierbei können beim Einziehen der Stengel Reibungswiderstände auftreten.A harvesting device is known from EP-91 635 B1, at which as a counter-holder a trough-shaped Sheet metal is used, this partial sheathing as a baffle for the stems gripped by the roller serves. This can be done when retracting the stem Frictional resistances occur.
Aus der gattungsbildenden DE-40 36 717 A1 ist ein Erntegerät bekannt, bei welchem als Gegenhalter eine Gegenwalze vorgesehen ist, die ebenso wie der Ein zugsrotor angetrieben ist, wobei über einen Verzah nungstrieb diese beiden Walzen so miteinander ver bunden sind, daß sie stets die gleiche Stellung zu einander einnehmen. Die Gegenwalze ist dabei eben falls mit Flügel od. dgl. ausgerüstet, die beim Um lauf der beiden Walzen in die Zwischenräume der Ar beitskanten der Einzugswalze greifen.From the generic DE 40 36 717 A1 is a Harvester known, in which a counter-holder Counter roll is provided, as is the one Zugsrotor is driven, with a tooth The drive between these two rollers are bound to always have the same position take each other. The counter roller is flat if equipped with wings or the like run the two rollers into the spaces between the ar grasp the edges of the feed roller.
Der Erfindung liegt die Aufgabe zugrunde, ein mög lichst kostengünstig ausgebildetes Erntegerät zu schaffen, bei welchem einerseits die durch den Pflückspalt eingezogenen Stengel sicher nach unten geführt werden, andererseits die durch eine Teilum mantelung entstehenden Reibungen vermieden werden und außerdem ein kostenaufwendiger Antrieb für die Einzugseinrichtungen vermieden wird. The invention has for its object a poss harvesters that are designed as inexpensively as possible create, on the one hand, by the Stalk retracted stalk securely down are led, on the other hand, through a part The resulting friction can be avoided and also a costly drive for the Feeding devices is avoided.
Diese der Erfindung zugrundeliegende Aufgabe wird dadurch gelöst, daß gemäß der Erfindung vorgeschla gen wird, daß anstelle der Teilummantelung nunmehr eine Gegenwalze vorgesehen wird, die an ihrem Umfang aber arbeitskantenfrei oder arbeitskantenlos ist, so daß eine Synchronisation zwischen der Gegenwalze und der eigentlichen Einzugswalze nicht erforderlich ist.This object underlying the invention will solved in that proposed according to the invention gene is that now instead of the partial sheathing a counter roll is provided on its circumference but is free of working edges or without working edges, so that synchronization between the counter roll and the actual feed roller is not required is.
Die Gegenwalze kann dabei angetrieben oder nicht an getrieben sein, und die Oberfläche der Gegenwalze kann aufgerauht oder glatt ausgebildet sein.The counter roller can be driven or not be driven, and the surface of the counter roll can be roughened or smooth.
Ein Ausführungsbeispiel der Erfindung wird nachfol gend anhand der Zeichnung erläutert.An embodiment of the invention will follow explained using the drawing.
In der Zeichnung ist mit 2 ein Einzugsrotor bezeich net, der an seinem Umfang mit Arbeitskanten 3 ausge rüstet ist und der in eine umdrehende Bewegung durch einen entsprechenden Antrieb, der nicht dargestellt ist, versetzt wird.In the drawing, 2 with a feed rotor is designated, which is equipped on its circumference with working edges 3 and which is set in a rotating movement by a corresponding drive, which is not shown.
Mit dem Einzugsrotor 2 arbeiten Zerkleinerungsmesser 4 zusammen, wobei in den Arbeitskanten 3 Schlitze vorgesehen sind, in die die Zerkleinerungsmesser 4 hineinragen können. Die Zerkleinerungsmesser 4 werden von einem Rahmen getragen, der an seiner Oberseite einen Pflückspalt 6 aufweist.Comminution knives 4 work together with the feed rotor 2 , 3 slots being provided in the working edges into which the comminution knives 4 can protrude. The shredding knives 4 are carried by a frame which has a picking gap 6 on its upper side.
Dem Einzugsrotor 2 gegenüberliegend ist eine Gegen walze 5 vorgesehen, die keine Arbeitskanten auf weist, sondern an ihrer Oberfläche im wesentlichen glatt oder leicht aufgerauht ausgebildet ist. Diese Gegenwalze 5 kann dabei angetrieben werden oder freilaufend ausgebildet sein, wobei auch für den Fall, daß die Gegenwalze 5 angetrieben ist, eine kostenaufwendige Synchronisation zwischen der Um laufbewegung der Gegenwalze 5 und der Umlaufbewegung des Einzugsrotors 2 nicht erforderlich ist.The feed rotor 2 opposite a counter roller 5 is provided, which has no working edges, but is formed on its surface substantially smooth or slightly roughened. This counter-roller 5 can be driven or designed to be free running, and even in the event that the counter-roller 5 is driven, a costly synchronization between the order of the counter-roller 5 and the orbital movement of the feed rotor 2 is not required.
Die vorderen Bereiche der Arbeitskanten 3 streichen in geringem Abstand an der Oberfläche der Gegenwalze 5 vorbei und nehmen dadurch die sich an die Gegen walze 5 anlegenden Stengel mit nach unten.The front areas of the working edges 3 sweep past the surface of the counter-roller 5 at a small distance and thereby take the stem 5 resting against the counter-roller with them down.
