Description
"Pflückvorsatz für ein Emtegerat zum Ernten von Körnerfrüchten""Picking attachment for a grain harvesting device"
Die Erfindung bezieht sich auf einen Pflückvorsatz gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a header according to the preamble of the main claim.
Ein gattungsbildender Pflückvorsatz wird in der DE 43 44 669 C1 beschrieben. Bei dieser bekannten Anordnung ist z. B. bei einer Ausführungsform nur ein Einzugsrotor vorgesehen, der mit auf einer umlaufend angetriebenen Welle angeordneten Schneidscheiben zusammenwirkt. Als Gegenhalter für die von dem Einzugsrotor durch den Pflückspalt gezogenen Pflanzenstengel ist eine sogenannte Teilummantelung vorgesehen.A generic picking attachment is described in DE 43 44 669 C1. In this known arrangement, for. B. only one feed rotor is provided in one embodiment, which interacts with cutting disks arranged on a rotating shaft. A so-called partial sheathing is provided as a counterhold for the plant stems drawn through the picking gap by the feed rotor.
Bei anderen Ausführungsformen, die in dieser Literaturstelle be- schrieben sind, sind zwei Einzugsrotoren vorgesehen, denen ein dritter Schneidrotor zugeordnet ist. Der durch die Teilummantelung bedingte Reibungswiderstand wird bei diesen Anordnungen aufgehoben, da die Einzugsrotoren angetrieben sind. Diese bekannten Anordnungen bauen aber relativ hoch und sind damit auch gewichtsmäßig erheblich belastet.
Aus der DE 94 03 265 U1 ist es schließlich bekannt, auch mehrere Schneidscheiben oder Schneidwalzen einzusetzen, die aber wiederum eine Gewichtserhöhung bedeuten.In other embodiments, which are described in this literature reference, two feed rotors are provided, to which a third cutting rotor is assigned. The frictional resistance caused by the partial sheathing is eliminated in these arrangements, since the feed rotors are driven. However, these known arrangements build relatively high and are therefore also heavily loaded in terms of weight. Finally, it is known from DE 94 03 265 U1 to also use several cutting disks or cutting rollers, which in turn mean an increase in weight.
Der Erfindung liegt die Aufgabe zugrunde, die bekannte Anordnung dahingehend zu verbessern, daß das Gesamtgewicht des Pflückers, insbesondere wichtig dann, wenn es sich um einen vielreihigen Pflücker handelt, herabzusetzen, dabei aber gleichgute Leistungen zu erzielen.The invention has for its object to improve the known arrangement in such a way that the total weight of the picker, especially important when it is a multi-row picker, to reduce, but to achieve equally good performance.
Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.
Mit anderen Worten ausgedrückt wird vorgeschlagen, daß einem Einzugsrotor ein Schneidrotor zugeordnet ist, wobei derIn other words, it is proposed that a cutting rotor is assigned to a feed rotor, the
Schneidrotor aus den eigentlichen Schneidscheiben besteht, die mit den Schlitzen in den Flügeln des Einzugsrotors zusammenwirken, wobei zwischen den einzelnen Schneidscheiben Rotorelementscheiben vorgesehen sind, die das Einziehen der Pflanze durch den Pflückspalt erleichtern. Im Gegensatz zu derCutting rotor consists of the actual cutting disks, which interact with the slots in the wings of the feed rotor, rotor element disks being provided between the individual cutting disks, which facilitate the drawing in of the plant through the picking gap. In contrast to the
Einrichtung, wie sie in der EP 474 072 A1 beschrieben wird, wird bei dieser Anordnung ein freier Schnitt erzielt, d. h. die erhebliche Reibung, die bei dieser vorbeschriebenen bekannten Anordnung noch auftritt, wird vermieden und es wird eine ge- samte Baugruppe gegenüber dem gattungsbildenden Stand derDevice as described in EP 474 072 A1, a free cut is achieved with this arrangement, i. H. the considerable friction that still occurs in this known arrangement described above is avoided and an entire assembly is compared to the generic state of the art
Technik vermieden, so daß die erfindungsgemäße Pflückeinrichtung wesentlich leichter ist und damit schnellere Arbeitsweisen der Maschinen ermöglicht.Technology avoided, so that the picking device according to the invention is much lighter and thus enables faster working of the machines.
Die Rotorelemente können dabei ebenfalls mit Einzugsflügeln ausgerüstet sein, können aber auch an ihrer Oberfläche glatt sein, d. h. ohne vorstehende Elemente ausgerüstet sein, wobei die Oberfläche an sich aufgerauht oder sonstwie behandelt werden kann.
Zwei Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnungen erläutert. Die Zeichnungen zeigen dabei inThe rotor elements can also be equipped with intake blades, but can also be smooth on their surface, ie without any protruding elements, the surface itself being roughened or otherwise treated. Two embodiments of the invention are explained below with reference to the drawings. The drawings show in
Fig. 1 in einem schematischen Schnitt eine erste Ausführungsform mit Rotorelementen, die mit Einzugsflügeln ausgerüstet sind und in Fig. 2 ebenfalls in einem schematischen Schnitt einFig. 1 shows a schematic section of a first embodiment with rotor elements which are equipped with feeder blades and in Fig. 2 also in a schematic section
Rotorelement, das an seiner Außenseite im wesentlichen eben, ohne Vorsprünge ausgerüstet ist.Rotor element, which is equipped on its outside essentially flat, without projections.
In den Zeichnungen sind mit 1 und 2 zwei Rahmenträger bezeichnet, von denen Pflückplatten 3 und 4 getragen werden, die ihrerseits den sogenannten Pflückspalt 5 definieren. Unterhalb der Pflückplatte 3 ist bei dem dargestellten Ausführungsbeispiel gemäß den Fig. 1 und 2 ein Einzugsrotor 6 angeordnet, der in Richtung des eingezeichneten Pfeiles umlaufend angetrieben wird. Der Rotor 6 ist mit Flügeln 7 ausgerüstet, die Schlitze auf- weisen, in die die noch zu erläuternden Schneidscheiben eingreifen können.In the drawings, 1 and 2 denote two frame supports, of which picking plates 3 and 4 are carried, which in turn define the so-called picking gap 5. Arranged below the picking plate 3 in the exemplary embodiment shown in FIGS. 1 and 2 is a feed rotor 6, which is driven in rotation in the direction of the arrow shown. The rotor 6 is equipped with vanes 7 which have slots in which the cutting disks to be explained can engage.
Auf einer in der Zeichnung nicht dargestellten Welle 10 sind Schneidscheiben 8 vorgesehen, die an ihrer Außenkante einen wellenförmigen Schliff aufweisen können, wobei zwischen den einzelnen Schneidscheiben 8 Rotorelemente 9 vorgesehen sind. Diese Rotorelemente 9 laufen zwangsläufig mit den Schneidscheiben 8 um, und zwar in der gleichen Richtung, da sie drehfest mit der die Schneidscheiben 8 antreibenden Welle verbun- den sind.On a shaft 10, not shown in the drawing, cutting disks 8 are provided, which may have a wavy cut on their outer edge, 8 rotor elements 9 being provided between the individual cutting disks. These rotor elements 9 inevitably rotate with the cutting disks 8, in the same direction, since they are connected in a rotationally fixed manner to the shaft driving the cutting disks 8.
Bei dem in Fig. 1 dargestellten Ausführungsbeispiel weist das Rotorelement 9 Einzugsflügel 11 auf, die mit den Einzugsflügeln 7 des Einzugsrotors 6 auf Lücke arbeiten, so daß die Dreh- geschwindigkeit der beiden Rotoren 6 und 9 aufeinander abgestimmt sein muß.
Die über die Oberkante der Rotorelemente 9 vorstehenden Einzugsflügel 11 erleichtern das Einziehen der zu bearbeitenden Pflanzen.In the exemplary embodiment shown in FIG. 1, the rotor element 9 has feed vanes 11 which work with the feed vanes 7 of the feed rotor 6 so that the rotational speed of the two rotors 6 and 9 must be coordinated with one another. The projecting wings 11 projecting above the upper edge of the rotor elements 9 facilitate the drawing in of the plants to be processed.
Bei der Ausführungsform gemäß Fig. 2 ist ein Rotorelement 9a vorgesehen, das so ausgebildet ist, daß über seinen Außenumfang keine Vorsprünge vorstehen. Hierbei kann natürlich der Außenumfang dieses Rotorelementes 9a aufgerauht oder sonst den Einzug der Pflanze erleichternd bearbeitet sein.
In the embodiment according to FIG. 2, a rotor element 9a is provided which is designed such that no projections protrude over its outer circumference. Here, the outer circumference of this rotor element 9a can of course be roughened or otherwise machined to facilitate the induction of the plant.
