Abstract

The vertical drive shaft of the hydraulic motor is connected by means of two crank arms to the arm of two two-armed levers which are pivot-mounted and are hinged with the other arm to the top or bottom cutter of a mower-cutter bar. The length of the front lever arm touching the blades corresponds to the lever-length of the pusher pieces of the mower-cutter bar. the crank arms can be on the same horizontal plane. A casing encloses the drive-mechanism, with the front end closed at the top right over the horizontal transmission pieces, and the side walls diverging away from the direction of travel.

Description

"Vorrichtung zum Antrieb der Doppelmesser eines Mähwerkes" Die Erfindung betrifft eine Vorrichtung zum Antrieb der Doppelmesser eines Mähwerkes, das an einer fahrbaren Arbeitsmaschine angeordnet ist, wobei die Antriebsvorrichtung vorzugsweise als Mittelantrieb ausgebildet ist, der in horizontaler Ebene liegende Übertragungselemente aufweist, die mit ihrem einen Ende gelenkig an den beiden Messern angreifen."Device for driving the double knife of a mower" The invention relates to a device for driving the double knife of a mower, which is attached to a mobile work machine is arranged, wherein the drive device is preferably is designed as a central drive, the transmission elements lying in the horizontal plane has, which at one end articulately attack the two knives.

Eine derartige Vorrichtung ist durch die DT-OS 1 962 701 bekanntgeworden. Der Antrieb besteht aus in vertikaler und horizontaler Ebene liegenden, vom vorderen Ende einer Motorwelle der Arbeitsmaschine her angetriebenen Antriebs-Übertragungsteilen. Da die Motorwelle der Arbeitsmaschine horizontal angeordnet ist, müssen in vertikaler Ebene liegende Antriebsteile vorgesehen werden, die über einen Kurbeltrieb und ggf. unter Zwischenschaltung eines Getriebes mit der Motorwelle der Arbeitsmaschine bewegungsmäßig gekoppelt sind.Such a device has become known from DT-OS 1 962 701. The drive consists of lying in the vertical and horizontal plane, from the front End of a motor shaft of the work machine driven drive transmission parts. Since the motor shaft of the working machine is arranged horizontally, it must be vertical Drive parts lying flat are provided, which via a crank drive and possibly with the interposition of a gear with the motor shaft of the machine in terms of movement are coupled.

Ein wesentlicher Nachteil dieses bekannten Mittelantriebs liegt in dessen konstruktivem Aufwand, der in erster Linie dadurch bedingt ist, daß zwischen der horizontal gelagerten Motorwelle als Antrieb und den ebenfalls in einer horizontalen Ebene gelagerten Schneidmessern eine zweimalige Umlenkung der Kraftübertragung um jeweils 900 erforderlich ist. Nachteilig ist ferner, daß der vorbekannte Mittelantrieb sehr groß baut.A major disadvantage of this known central drive is in its constructive effort, which is primarily due to the fact that between the horizontally mounted motor shaft as the drive and also in a horizontal one The cutting knives on the level bearings divert the power transmission twice 900 is required each time. Another disadvantage is that the previously known central drive builds very large.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Antriebsvorrichtung konstruktiv zu vereinfachen, weniger störanfällig zu machen und in ihren baulichen Abmessungen zu verkleinern.The invention is based on the object of the known drive device to simplify constructively, to make less prone to failure and in their structural Reduce dimensions.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Antrieb durch einen separaten Motor, vorzugsweise einen Hydraulikmotor mit lotrechter Antriebswelle gebildet wird, die über Kurbelarme unmittelbar gelenkig mit dem anderen Ende der horizontalen Übertragungselemente verbunden ist.This object is achieved according to the invention in that the drive by a separate motor, preferably a hydraulic motor with a vertical drive shaft is formed, which is directly articulated to the other end of the via crank arms horizontal transmission elements is connected.

Der große Vorteil der neuen Konstruktion ist darin zu sehen, daß zwischen Motor und Schneidmessern nur sich in horizontalen Ebenen bewegende Ubertragungselemente vorgesehen sind. Dadurch kann die Konstruktion insgesamt überraschend einfach und damit robust gestaltet werden. Der separate Hydraulikmotor sowie die einzelnen Ubertragungselemente bilden eine sehr kleine, kompakte Baueinheit.The big advantage of the new design is that between Motor and cutting blades only transfer elements moving in horizontal planes are provided. As a result, the overall construction can be surprisingly simple and thus designed to be robust. The separate hydraulic motor and the individual transmission elements form a very small, compact unit.

Der neue Antrieb läßt sich daher auch an Booten anbringen zur Bearbeitung von Uferböschungen oder dergleichen. In diesem Fall kann der Hydraulikmotor unmittelbar an der Bootswandung befestigt sein.The new drive can therefore also be attached to boats for processing embankments or the like. In this case, the hydraulic motor can immediately be attached to the boat wall.

Der Antrieb muß nicht unbedingt als Mittelantrieb ausgelegt sein.The drive does not necessarily have to be designed as a central drive.

Es ist vielmehr auch möglich, den Hydraulikmotor seitlich anzuordnen und z.B. an dem unteren Führungsarm des Mähbalkens zu befestigen.Rather, it is also possible to arrange the hydraulic motor laterally and e.g. to be attached to the lower guide arm of the cutter bar.

In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung dargestellt. Es zeigen: Fig. 1 eine Antriebsvorrichtung in Vorderansicht und Fig. 2 einen Schnitt gemäß der Linie II - II in Fig. 1 Danach besteht die dargestellte Vorrichtung aus einem Hydraulikmotor 1 mit lotrechter Antriebswelle 2, die über zwei Kurbelarme 3 unmittelbar gelenkig verbunden ist mit dem einen Arm zweier zweiarmiger Hebel 4, die bei 5 drehbar gelagert sind und mit ihrem anderen Arm an einem Obermesser 6 bzw. einem Untermesser 7 eines Mähbalkens angelenkt sind. Dabei entspricht die Länge des vorderen, an den Messern 6,7 angreifenden Hebelarmes der Hebellänge der Drücker 8 des Mähbalkens.In the drawing, an exemplary embodiment is shown in FIG Invention shown. 1 shows a drive device in a front view and FIG. 2 shows a section along the line II-II in FIG Device consisting of a hydraulic motor 1 with a vertical drive shaft 2, which over two crank arms 3 is directly articulated to one arm of two two-armed Lever 4, which are rotatably mounted at 5 and with their other arm on an upper knife 6 or a lower knife 7 of a cutter bar are articulated. The Length of the front lever arm acting on the knives 6.7 of the lever length of the Trigger 8 of the cutter bar.

In einer zweckmäßigen Ausführungsform können die Kurbelarme 3 in derselben horizontalen Ebene angeordnet sein. Dadurch läßt sich die Bauhöhe des Antriebes noch weiter verringern. Durch die niedrigere Anordnung des Hydraulikmotors 1 ergeben sich auch Vorteile hin-9ichtlich der Stabilität und der Eigenschwingungen.In an expedient embodiment, the crank arms 3 in the same be arranged in the horizontal plane. This allows the overall height of the drive decrease even further. The lower arrangement of the hydraulic motor 1 results There are also advantages in terms of stability and natural vibrations.

Schließlich kann auch ein in der Zeichnung nicht dargestelltes, den Antrieb umschließendes Gehäuse vorgesehen werden, dessen Stirnseite von oben bis über die horizontalen Übertragungselemente 4 geschlossen und dessen Seitenwandungen entgegen der Arbeits- bzw.Finally, a not shown in the drawing, the Drive enclosing housing are provided, the end face from above to Closed over the horizontal transmission elements 4 and its side walls contrary to the work resp.

Fahrtrichtung divergierend ausgebildet sind. Dadurch wird sichergestellt, daß das durch den verbleibenden Einzugsspalt in das Gehäuse eintretende Schnittgut auf der Gehäuserückseite einwandfrei abgeleitet wird, ohne sich im Gehäuse zu stauen. Grundsätzlich wäre es aber auch möglich, die Stirnseite des Gehäuses keilförmig auszubilden, um das Schnittgut zu beiden Seiten abzulenken.Direction of travel are designed to diverge. This ensures that the clippings entering the housing through the remaining intake gap on the rear of the housing is properly discharged without jamming in the housing. In principle, however, it would also be possible for the end face of the housing to be wedge-shaped train to deflect the clippings on both sides.
