Abstract
Description
Die Erfindung bezieht sich auf ein Mähwerk mit zumindest einem Paar um lotrechte Achsen gegenläufig ange triebener Mähkreisel, an deren Mähscheiben radial Messer angeordnet sind.The invention relates to a mower with at least opposed to a pair around perpendicular axes driven mower rotor, on the mower discs radial knives are arranged.
Bei einem bekannten Mähwerk der im Oberbegriff des An spruchs 1 aufgeführten Gattung (Prospekt "Deutz-Fahr S.M. 50 F" , Drucknummer 91 44 901, Druckdatum 7/83) sind die Mähscheiben aus Stahlblech hergestellt, wobei die Messer radial und pendelnd gelagert an den tellerartig ausgebil deten Mähscheiben befestigt sind. Aufgrund der Herstellung der Mähscheiben aus relativ dickwandigem Stahlblech sind das Gewicht und der Herstellungsaufwand der Mähscheiben relativ hoch.In a known mower in the preamble of An Proverb 1 listed genus (prospectus "Deutz-Fahr S.M. 50 F ", print number 91 44 901, print date 7/83) are the Mower discs made of sheet steel, with the knives mounted radially and oscillating on the plate-like design the mowing discs are attached. Because of the manufacture the mower discs are made of relatively thick-walled sheet steel the weight and manufacturing effort of the mower discs quite high.
Der Erfindung liegt daher die Aufgabe zugrunde, diese Nachteile zu vermeiden und somit das Gesamtgewicht des Mähwerks und den Fertigungsaufwand für die Herstellung der Mähscheiben deutlich zu reduzieren.The invention is therefore based on the object To avoid disadvantages and thus the total weight of the Mower and manufacturing costs for the manufacture of the Reduce mowing discs significantly.
Diese Aufgabe wird an einem Mähwerk der in Rede stehenden Gattung durch die im Kennzeichen des Anspruchs 1 aufge führten Merkmale gelöst.This task is performed on a mower deck Genus by the in the characterizing part of claim 1 led characteristics solved.
Durch die Herstellung der Mähscheiben aus Kunststoff läßt sich deren Eigengewicht erheblich reduzieren, wobei eine kostengünstige Fertigung der Mähscheiben möglich ist.By making the plastic mower discs their own weight is significantly reduced, with one inexpensive manufacture of the mower discs is possible.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 9 aufgeführt. Es wird danach alternativ vorgeschlagen, bei der Verwendung pendelnd gelagerter Messer, deren Haltebolzen in den Kunststoff einzugießen oder bei einer segmentartigen, symmetrischen Ausbildung der Mähscheibe die Messer im Randbereich der Schenkel der Segmente direkt einzugießen. Bei letzterer Version ist im Falle eines Messerverschleißes die Mäh scheibe einfach zu wenden.Further advantageous embodiments of the invention are in subclaims 2 to 9. It will be afterwards alternatively suggested swinging when using stored knife, its retaining bolt in the plastic pour or with a segment-like, symmetrical Training the mower disc in the edge area of the Pour the legs of the segments directly. With the latter Version is the mower in case of knife wear easy to turn.
Zur weiteren Erläuterung der Erfindung wird auf die Zeich nung verwiesen, in der ein Ausführungsbeispiel vereinfacht dargestellt ist.To further explain the invention, reference is made to the drawing referred to, in which an embodiment is simplified is shown.
Es zeigen:Show it:
Fig. 1 eine segmentartig ausgebildete Mähscheibe in Drauf sicht und Fig. 1 is a segment-like mower disc in plan view and
Fig. 2 einen Schnitt durch die Mähscheibe nach Fig. 1 gemäß Linie II-II. Fig. 2 shows a section through the mower disc of FIG. 1 along line II-II.
In den Fig. 1 und 2 ist mit 1 eine Mähscheibe be zeichnet, die im Bereich einer zentrischen Bohrung 2 auf einer nicht dargestellten Antriebswelle eines Mähwerks befestigt ist. Die Mähscheibe 1 ist segmentartig ausgebil det, wobei an Schenkeln 3 des Restquerschnitts im Umfangs bereich jeweils Messer 4 in den Kunststoff der Mähscheibe eingegossen sind.In Figs. 1 and 2 is characterized by be a cutting disc 1, which is fastened in the region of a central bore 2 to an unillustrated drive shaft of a mower. The mower disc 1 is segment-like ausgebil det, knives 4 are cast into the plastic of the mower disc on legs 3 of the remaining cross-section in the circumferential area.
