Abstract

The harvester has a chopper/cutter drum, whose blades coacting with a fixed counter blade, are in the form of straight strips spaced by less than 120 mm measured from the peripheral direction of the drum. Each pair of blades (2) is connected with the cutter drum (3) via a common fixing device (9, 10). Each pair is integrally formed in the shape of a U-rail and is releasably connected with the drum (3) via the cross-piece (9). The blades (2) are radial to th axis of rotation (5) of the cutter drum (3).

Description

Feldhäcksler für die MaiskolbenernteForage harvester for the corn cob harvest

Die Erfindung betrifft einen Feldhäcksler nach dem Gattungsbegriff des Patentanspruches 1.The invention relates to a forage harvester according to the generic term of claim 1.

Bei bekannten Feldhäckslern dieser Art sind, wie beispielsweise aus der DOS 2 406 275 zu ersehen, die als Schlagleisten auagebildeten Häckselmesser an mit der Häckseltrommel verbundenen Trägern angeschraubt. Für jedes Messer ist hierbei ein eigener Träger mit Verschraubung für die Messerbefestigung vorgesehen, was die bekannte Ausführung bei der großen Anzahl der für die Maiskolbenzerkleinerung verwendeten Messer in der Herstellung und Montage sehr zeit- und damit auch kostenaufwendig macht. Außerdem ist es bei einer in der Praxis verwendeten Ausführung nach der DOS 2 406 275 infolge der zwischen den Messerhaltern notwendigen Freiräume für die Befestigung der Messer nicht möglich, mehr als 18 Messer an der Häckseltrommel anzubringen. Wünschenswert für die Funktion der Maiskolbenzerkleinerung sind jedoch Häckseltrommeln mit 20 und mehr Messern.In known forage harvesters of this type, such as from of DOS 2 406 275, the chopping knives designed as blow bars screwed to supports connected to the cutterhead. For every knife is here a separate carrier with screw connection for the knife attachment is provided, what the known design with the large number of for the corn cob crushing used knives in the production and assembly very time-consuming and thus also costly power. In addition, it is in a version used in practice according to the DOS 2 406 275 due to the clearance required between the knife holders for attachment the knife not possible to attach more than 18 knives to the cutterhead. However, chopping drums are desirable for the function of the corn cob comminution with 20 or more knives.

Bei der erfindungsgemäßen Ausgestaltung einer Häckseltrommel nach den kennzeichnenden Merkmalen der Patentansprüche 1 oder 2 und 3 ist demgegenüber die Herstellung der Häckseltrommel wesentlich vereinfacht, und es besteht die Möglichkeit, an Häckseltrommeln mit üblichem Durchmesser ohne Schwierigkeit 20 und mehr Messer anzubringen.In the embodiment of a chopping drum according to the invention the characterizing features of claims 1 or 2 and 3 is on the other hand the production of the cutterhead is significantly simplified, and there is the possibility of on chopping drums with the usual diameter, 20 or more knives without difficulty to attach.

Die in Unteranspruch 4 vorgeschlagene Maßnahme bringt neben einer Vereinfachung der Messerhalterung und Messerbefestigung an der Häckseltrommel den Vorteil, daß beim Häckselvorgang der Vorschub der zugeführten Maiskolben am Außenumfang des geschlossenen Trommelmantels begrenzt wird und somit keine größeren Maiskolbenstücke in das Innere der Häckseltromnel gelangen und demzufolge unzerkleinert zur Silage kommen können.The measure proposed in dependent claim 4 brings in addition to one Simplification of the knife holder and knife attachment to the chopping drum Advantage that during the chopping process the advance of the supplied corn cobs is limited on the outer circumference of the closed drum shell and thus no larger ones Corn on the cob get into the interior of the chopping drum and are therefore not crushed can come to the silage.

Die in der Zeichnung ausschnittsweise dargestellte, für die Maiskolbenernt verwendbare Häcknelmaschine weist eine in einem GehAuse 1 umlaufend angetriebene Hlckseltrommel 3 auf, deren als Schlagleisten dienende Messer 2 mit einer gehäusefesten Gegenechneide 4 zusammenwirken. Der Häckseltrommel 3 ist eine in an sich bekannter Weise aus umlaufend angetriebenen ZufUhr- und Preßorganen bestehende Fördervorrichtung 6 für die Zuführung der Maiskolben zur Häckseltrommel 3 vorgeordnet. Durch den Auslaß 7 wird das gehäckselte Erntegut in den Laderaum eines nachgezogenen oder nebenher fahrenden Wagens geschleudert.The one shown in detail in the drawing, for the corn on the cob harvest Usable shredding machine has a rotating in a housing 1 Hlckseltrommel 3, whose knives 2, which serve as beater bars, are fixed to the housing Counter cutting edge 4 interact. The chopping drum 3 is known per se Way from circulating feed and pressing members existing conveyor 6 upstream for feeding the corn cobs to the chopping drum 3. Through the outlet 7 is the chopped crop in the hold of a trailed or next to it moving car.

Die H&ckseltrommel 3 weist einen um eine Achse S umlaufend angetriebenen geschlossenen zylindrischen Mantel 8 auf, an dessen Außenumfang die Messer 2 befestigt sind. Je 2 Messer 2 sind hierbei einstückig in Porm einer U-Schiene gestaltet und über deren Quersteg 9 mittels Schrauben lo mit dem geschlossenen Mantel 8 der Häckseltrommel 3 lösbar verbunden.The drum drum 3 has a drum driven to rotate about an axis S closed cylindrical jacket 8, on the outer circumference of which the knife 2 is attached are. 2 knives 2 each are designed in one piece in the form of a U-rail and via the crosspiece 9 by means of screws lo with the closed jacket 8 of the chopping drum 3 releasably connected.

Für eine starre Halterung der Messer 2 am Trommelmantel 8 sind die Quersteg 9 mit einem Radius gekrümmt gestaltet, der wenig kleiner als der Radius des Außenumfanges des Trommelmantels 8 ist.For a rigid mounting of the knife 2 on the drum shell 8 are the Crossbar 9 designed curved with a radius that is slightly smaller than the radius the outer circumference of the drum shell 8 is.
