Häcksel trommel für Häckselvorri chtungen» insbesondere FeldhäckslerChopping drum for chopping devices » especially forage harvesters
^te feuerung betrifft eine HMckseltronmel für Häckselvorrichtungen:, insbesondere Feldhäcksler, die an ihrem Umfang mehrere, mit Abstand voneinander angeordnete, wit einer feststehenden Segenschneide zusammenwirkende Schneidmesser aufweist, wobei der zur Drehachse der Häckseltrommel hin offene Bereich zwischen den Schneidmessern durch Abdeckunoen ganz oder teilweise geschl&ssen ist.The first firing concerns a Hckseltronmel for chopping devices :, in particular forage harvesters, which on their circumference have several, spaced apart, with a stationary Segenschneide has cooperating cutting knives, the area open to the axis of rotation of the chopping drum completely or partially between the cutting knives by covering is closed.
Beim Häckseln von Mais für Silagezwecke besteht die Gefahr, daß die Maiskolben oder KoIbenstücke, die sich in dem zur Häckselvorrichtung strömenden Futterpaket befinden, nicht in ausreichendem Maße zerkleinert werden. Der Grund hierfür ist, daß die auf aer Gegenschneide aufliegenden Kolbenstücke vom Schneidmesser angeschlagen und hinter dem Schneidmesser in das Innere der Häcksel trommel geschleudert werden. Derartig großstückiges Häckselgut v/ird für die nachfolgende Silage nicht gewünscht.When chopping maize for silage purposes, there is a risk that the cobs or pieces of cobs that are in the fodder package flowing to the chopping device are not sufficiently comminuted. The reason for this is that the piston pieces resting on the aer shearbar are struck by the cutting knife and thrown behind the cutting knife into the interior of the chopping drum. Such large chopped material is not desired for the subsequent silage.
Um das Eindringen von größeren Kolbenstücken in das Innere der Häcksel trommel zu vermeiden, wurde bereits vorgeschlagen,About the penetration of larger piston pieces into the interior avoiding the chopping drum has already been proposed
- 2 909834/0103 - 2 909834/0103
zwischen den Schneidmessern Abdeckbleche anzuordnen, die mit der Häcksel trommel verbunden sind und innerhalb des Umlaufkreises der Schneidkanten der Schneidmesser liegen. Diese Abdeckbleche werden mit Schrauben an der Häckseltrommel befestigt» wobei die Schraubenköofe am Außenumfang der Häcksel trommel liegen.to arrange cover plates between the cutting blades, which with the Chopping drum are connected and within the orbit the cutting edges of the cutting knives. These cover plates are attached to the cutterhead with screws »whereby the Screw heads lie on the outer circumference of the chopping drum.
Die bekannten Abdeckbleche halten zwar größere Kolbenstücke davon ab, 1n das Innere der Häckseltrommel einzudringen. Mit den Abdeckblechen läßt sich iedoch nicht verhindern, daß das Futterpaket, nachdem es durchgeschnitten ist, unmittelbar hinter der Schneidkante in Richtung auf die Häcksel trommel expandiert. Die Geschwindigkeit in Richtung Häckseltrommel ist dadurch kurzzeitig um ein Vielfaches höher als die Vorschubgeschwindinkeit. Dadurch kann bereits eine unerwünscht große Schnittlänge des Häckselgutes entstehen.The known cover plates keep larger piston pieces from penetrating the inside of the chopping drum. With the Cover plates can iedoch not prevent that the lining package, after it has been cut through, immediately behind the Cutting edge expanded towards the chopping drum. The speed in the direction of the cutterhead is therefore brief many times higher than the feed speed. Through this an undesirably long cut length of the chopped material can arise.
Ein weiterer Nachteil der bekannten Ausführung ist dadurch gegeben, daß durch die separate Befestigunq der Abdeckbleche an der Häcksel trommel ein erhöhter Montage- und Demontageaufwand entsteht.Another disadvantage of the known design is that due to the separate fastening of the cover plates the chopping drum an increased assembly and disassembly effort.
Der Neuerung liegt die Aufgabe zugrunde, die bekannte Ausführung dadurch zu verbessern, daß eine möglichst kurze und gleichmäßige Schnittlänge des Häckselgutes erzielt und die Montage vereinfacht wird.The innovation is based on the task of improving the known design in that a short and as possible uniform cutting length of the chopped material is achieved and assembly is simplified.
- 3 -909834/0103- 3 -909834/0103
Gemäß der Neuerung wird dies dadurch erreicht, daß sich die Abdeckungen unmittelbar an die Schneidkante der Schneidmesser anschließen und in Verlänqeruna der Schneidkante entgegen der Umlaufrichtung der Häcksel trommel verlaufen. Dabei sind die Abdeckungen konvex gekrümmt und bilden eine Führungsfläche für das einströmende Futterpaket. Dadurch wird verhindert, daß das Futterpaket nach dem Durchschneiden in Richtung der Häckseltrommel expandiert.According to the innovation, this is achieved in that the covers are directly on the cutting edge of the cutting knife connect and extend the cutting edge against the The direction of rotation of the chopping drum run. There are those Covers convexly curved and form a guide surface for the incoming feed package. This prevents the forage package from being cut in the direction of the chopping drum expands.
Damit eine exakte Schnittlänge eingehalten werden kann, liegt die Führungsfläche auf einer Spirale, deren Radius-verringerung über dem Teilungswinkel der Schneidmesser der Schnittlänge des Häckselgutes entspricht.So that an exact cutting length can be maintained, the guide surface lies on a spiral whose radius is reduced over the pitch angle of the cutting knife corresponds to the cutting length of the chopped material.
Eine einfache Montage der Abdeckungen wird dadurch erreicht, daß die Abdeckungen Halter aufweisens die zusammen mit den Schneidmessern an einem Messerträger der Häcksel trommel anschraubbar sind.A simple assembly of the covers is achieved in that the holder covers comprise s the drum are screwed together with the cutting blades at a blade carrier of the chaff.
Vorteilhafterweise ist die Länge der Abdeckungen in Umfangsrichtung gesehen mindestens gleich der Höhe der Schnittfläche des zu häckselnden Futterpaketes.The length of the covers is advantageously in the circumferential direction seen at least equal to the height of the cut surface of the forage package to be chopped.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die sich unmittelbar an die Schneidkante anschließende Abdeckung als Führungsfläche für das angeschnitteneThe advantages achieved by the invention are in particular that the directly adjoining the cutting edge Cover as a guide surface for the cut

Futterpaket dient. Die Abdeckung bzw. deren Führungsfläche verhindert die normalerweise hinter der Schneidkante einsetzende Expansion des Führungspakets, die zu einer größeren Schnittlänge des Häckselgutes führt. Außerdem bringt die Befestigung der Abdeckungen zusammen mit den Schneidmessern an der Häcksel trommel neben Kosteneinsparungen auch eine erhebliche Erleichterung bei der Montage und Demontage.Feed package is used. The cover or its guide surface prevents the normally occurring behind the cutting edge Expansion of the guide package, resulting in a greater cutting length of the chopped material leads. Also brings the attachment of the covers Together with the cutting knives on the chopping drum, this also makes it considerably easier to save costs assembly and disassembly.
In der nachfolgenden Beschreibung und der Zeichnung, die ein AusfUhrungsbeispiel darstellt, ist die Erfindung näher erläutert.The invention is described in greater detail in the following description and the drawing, which shows an exemplary embodiment explained.
Am Umfang einer Häcksel trommel 1 sind mehrere Schneidmesser 2 an Messerträgern 3 mit Schrauben 4 befestigt. Mit den Schrauben 4 ist jeweils eine Abdeckunq 5 am Rücken des Schneidmesers angeschraubt.On the circumference of a chopping drum 1, several cutting knives 2 are attached to knife carriers 3 with 4 screws. With the screws 4 a cover 5 is screwed to the back of the cutting knife.
Die Abdeckung 5 besteht aus einem gekrümmten, eine Führungsfläche 6 bildenden Blech, das sich unmittelbar an eine Schneidkante 7 des Schneidmessers 2 anschließt. Die Fiihrungsflache 6 Hegt auf einer Spirale 8, die jeweils von einer Messerspitze zur Spitze des nachfolgenden Schneidmessers 2 verläuft. Die Radiusverringerung der Spirale 8 auf diesem Spiralenabschnitt entsoricht dabei der Schnittlänqp 9 des Häckselgutes.The cover 5 consists of a curved sheet metal forming a guide surface 6, which is located directly on a cutting edge 7 of the cutting knife 2 connects. The guide surface 6 Lies on a spiral 8, each of which runs from a knife tip to the tip of the following cutting knife 2. The radius reduction of the spiral 8 on this spiral section, the cutting length 9 of the chopped material is disposed of.
909834/010909834/010
An dem die Führungsflache 6 bildenden Blech sind zwei rechtwinklig abgebogene Halter 10 angeschweißt. Jeder Halter 10 weist eine Bohrung aufs die der Befestigungsbohrung des Schneidmessers 2 entspricht.Two holders 10 bent at right angles are welded to the sheet metal forming the guide surface 6. Each holder 10 has a bore s corresponding to the mounting hole of the cutting blade. 2
Das auf einer feststehenden Gegenschneide 11 aufliegende Futterpaket 12 wird durch nicht dargestellte Preßwalzen auf die Häcksel trommel zu bewegt. Gelangt das Futterpaket in den Bereich der Schneidmesser 2, so wird ein Teil des Futterpaketes abgeschnitten.Dabei verhindert die sich unmittelbar an die Schneidkante 7 des Schneidmessers 2 anschließende Abdeckung 5, daß sich das Futterpaket 12 sogleich hinter der Schneidkante 7 ausdehnt und dadurch die Schnittlänne 9 des Heckseigutes vergrößert wird.The resting on a fixed counter blade 11 Fodder package 12 is moved to the chopper drum by pressing rollers, not shown. The food package arrives in the area the cutting knife 2, part of the forage package is cut off prevents the directly adjoining the cutting edge 7 of the cutting knife 2 cover 5 that the feed package 12 expands immediately behind the cutting edge 7 and thereby the cutting length 9 of the stern cargo is increased.
