Abstract

The invention relates to a field chopper for agricultural crops, the chopping unit of which is followed by a pair of driven conditioning rollers, and provides that, without the use of intermediate conveyors, the pair of conditioning rollers is arranged directly behind the chopping unit in the lower region of the rising discharge shaft, in front of the post-accelerator provided in a way known per se in the upper region of the discharge shaft.

Description

FeldhäckslerForage harvester

Die Erfindung betrifft einen Feldhäcksler für landwirtschaftliches Erntegut mit den Merkmalen des Oberbegriffs des Patentanspruches.The invention relates to a forage harvester for agricultural use Crop with the features of the preamble of the claim.

In der europäischen Patentanmeldung 0 058 431 ist eine Futtererntemaschine beschrieben, deren Aufgabt es ist, das Häckselgut, insbesondere Mais, möglichst gleichmäßig und fein zu zerkleinern. Zu diesem Zweck ist in Flußrichtung der Messertrommel eine zusätzliche Zerkleinerungseinrichtung in Form zwei-er zusammenwirkender Konditionier- oder Quetschwalzen nachgeordnet. Von den Quetschwalzen wird das Häckselgut an zwei in Maschinenlängsrichtung ungeordnete Förderschnecken übergeben, die es einem Abgabegebläse bzw. Nachbeschleuniger zuführen. Diese Konstruktion ist durch die Verwendung einer Vielzahl von Verschleißteilen störanfällig und sehr aufwendig. Ein wesentlicher Nachteil ist darin zu sehen, daß die dem Häckselgut innewohnende, durch den Häcksel- und Quetschprozeß erzeugte Bewegungsenergie durch den Schneckentransport vernichtet und durch den Nachbeschleuniger erneut zugeführt werden muß.In European patent application 0 058 431 is a Forage harvester described, the task of which is to cut the chopped material, especially maize, as evenly as possible and finely chop. For this purpose, in the direction of flow of the cutterhead, there is an additional shredding device in the form of two interacting conditioning or nip rollers downstream. The chopped material is transferred from the squeeze rollers to two disordered ones in the longitudinal direction of the machine Transfer screw conveyors, which are fed to a discharge fan or Add post-accelerator. This construction is prone to failure due to the use of a large number of wear parts and very complex. A major disadvantage can be seen in the fact that the material inherent in the chopped material caused by the chopped The kinetic energy generated by the squeezing process is destroyed by the screw transport and supplied again by the post-accelerator must become.

Aufgabe der vorliegenden Erfindung ist es, einen Feldhäcksler der im Oberbegriff des Patentanspruches beschriebenen Art zu schaffen, in dem der Gutfluß zwischen dem Häcksler und dem Quetschaggregat sowie zwischen Quetschaggregat und dem Abgabegebläse ohne Zwischenschaltung weiterer Förderer erfolgt.The object of the present invention is to provide a forage harvester of the type described in the preamble of the claim create, in which the crop flow between the chopper and the crushing unit and between the crushing unit and the discharge fan takes place without the interposition of further conveyors.

Die Aufgabe wird mit den Merkmalen des einzigen Patentanspruches gelöst, und zwar in der Form, daß das Konditionierwalzenpacr ohne Verwendung von Zwischenförderern unmittelbar hinter dem Häckselaggregat im unteren Bereich des aufsteigenden AuswurfSchachtes vor dem in an sich bekannter Weise im oberen Bereich des Ausv/urfschachtes vorgesehenen Nachbeschleuniger bzw. Abgabegebläse angeordnet ist.The task is with the features of the single claim solved, in the form that the conditioning roller pacr directly without the use of intermediate conveyors behind the chopping unit in the lower area of the ascending discharge chute in front of the more familiar one Way in the upper area of the Ausv / urfschachtes provided post-accelerator or discharge fan is arranged.

Nachstehend wird die bevorzugte Ausführungsform der Er- " findung anhand der Zeichnungsfiguren beschrieben. Es zeigen:The preferred embodiment of the " Finding described using the drawing figures. Show it:

Figur 1 in schematischer Seitenansicht einen Feldhäcksler der in Rede stehenden Art undFigure 1 is a schematic side view of a forage harvester of the type in question and

Figur 2 eine vergrößerte Darstellung des Häckseiaggregates mit den sich anschließenden Fördereinrichtungen.Figure 2 is an enlarged view of the chopping unit with the adjoining funding facilities.

Mit 1 ist ein selbstfahrender Feldhäcksler bezeichnet, dessen vordere Einzugsorgane 2 das Erntegut einer mit Messern 3 besetzten Häckseltrorcmel 4 zuführen, die mit einem ortsfesten Gegenmesser 5 zusammenwirkt. Von dort aus gelangt das gehäckselte Gut in einen Auswurfschacht 6, in dem es zusätzlich zerkleinert und beschleunigt wird. Dem Schacht 6 schließt sich mittels eines Drehkranzes 7 ein Auswurfkrümmer 8 an, durch den das Häckselgut beispielsweise auf ein Begleit fahrzeug gefördert wird, !vie die Figur 2 zeigt, besteht die zusätzliche Zerkleincrungseinrichtung aus zwei profilierten Konditioni/rv:ulz-„r. 9 und 10, die gegenläufig angetrieben'werden. Das in Pfeilrichtung A von der Häckseltrommel abgegebene Gut gelangt zwischen die1 with a self-propelled forage harvester is referred to, whose front intake organs 2 feed the harvested material to a Häckseltrorcmel 4 equipped with knives 3, which with a stationary counter knife 5 cooperates. From there, the chopped material arrives in an ejection chute 6, in which it is also crushed and accelerated. The shaft 6 is closed by means of a turntable 7 Ejection chute 8, through which the chopped material is conveyed to an accompanying vehicle, for example,! Vie the FIG. 2 shows, the additional comminution device consists of two profiled conditioning units: ulz- "r. 9 and 10, which are driven in opposite directions. The one in the direction of arrow A Material discharged from the chopping drum gets between the

unmittelbar hinter der Häckseltromroel 4 im Einflußbereich des aufsteigenden Auswurfschachtes 6 angeordneten Konditionierwalzen 9 und 10, wobei vor allem die noch im Käckselgut befindlichen Körner angeschlagen bzv/. zerkleinert werden. Durch die hohe Umfangsgeschwindigkeit der Konditionierwalzen 9 und 10 wird das Häckselgut ohne Zwischenschaltung weiterer Förderer sicher bis in den Wirkungsbereich eines unterhalb des Drehkranzes 7 im Auswurfschacht 6 angeordneten Nachbeschleunigers 11, gefördert.immediately behind the chopping drum 4 in the area of influence of the ascending discharge chute 6 arranged conditioning rollers 9 and 10, especially those still in the chaff Grains chipped or /. be crushed. Due to the high peripheral speed of the conditioning rollers 9 and 10, the chopped material is safely transported into the effective area of one below the turntable without the interposition of further conveyors 7 in the discharge chute 6 arranged post-accelerator 11, promoted.
