Description

Scheibenegge Disc
Die Erfindung betrifft eine Scheibenegge gemäß des Oberbegriffes des Patentanspruches 1.The invention relates to a disc harrow according to the preamble of claim 1.
Derartige Scheibeneggen sind in der Praxis bekannt geworden. Diese Scheibeneggen weisen Scheiben gleichen Durchmessers auf. Aufgrund des gleichen Durchmessers der nach innen werfenden Außenscheiben wird eine zu große Arbeitsintensität im Außenbereich der Arbeitsbreite der Scheibenegge erzielt.Disc harrows of this type have become known in practice. These disc harrows have discs of the same diameter. Due to the same diameter of the inner discs throwing inwards, excessive work intensity is achieved in the outer area of the working width of the disc harrow.
Bei Scheibeneggen, deren Scheiben auf einer quer zur Fahrtrichtung verlaufenden Welle angeordnet sind, hat man diesen Nachteil dadurch zu vermeiden versucht, indem die nach innen werfende Außenscheibe einen kleineren Durchmesser als die übrigen Scheiben aufweist. Für eine Arbeitstiefe kann die Scheibenegge so eingestellt werden, dass die nach innen werfende Außenscheibe gerade die Bodenoberfläche berührt. Bei einer Vergrößerung der Arbeitstiefe der Scheibenegge leistet die nach innen werfende Außenscheibe eine zu große Arbeitsintensität, während bei einer geringen Arbeitstiefe die nach innen werfende Außenscheibe einen zu großen Abstand zur Bodenoberfläche hat, somit eine Wirkung entfaltet. Bei verschiedenen Arbeitstiefen brauchte man an sich Scheiben unterschiedlichen Durchmessers. Dieser Austausch ist sehr aufwendig und erfordert viele Scheiben unterschiedlichen Durchmessers .In disc harrows, the discs of which are arranged on a shaft running transversely to the direction of travel, attempts have been made to avoid this disadvantage by making the outer disc throwing inwards smaller in diameter than the other discs. For a working depth, the disc harrow can be adjusted in such a way that the outer disc throwing inwards just touches the ground surface. When the working depth of the disc harrow is increased, the outer disc throwing inwards produces too much work intensity, while when the working depth is shallow, the outer disc throwing inwards is too far away from the ground surface, and thus has an effect. At different working depths, disks of different diameters were needed. This exchange is very complex and requires many disks of different diameters.
Der Erfindung liegt die Aufgabe zugrunde, die Arbeitsweise der Scheiben einer Scheibenegge insbesondere im Außenbereich an die Arbeitsbedingungen bei unterschiedlichen Arbeitstiefen der Scheibenegge anpassen zu können. Diese Aufgabe wird erfindungsgemäß durch das kennzeichnende Merkmal des Patentanspruches 1 gelöst. Infolge dieser Maßnahme kann die nach innen werfende Außenscheibe optimal auf die Arbeitstiefe der Scheibenegge eingestellt werden. Die nach innen werfende Außenscheibe kann so eingestellt werden, dass sie mit der Scheibenunterkante gerade den Boden berührt. Somit kann die Außenscheibe bei allen einstellbaren Arbeitstiefen nur die Bodenoberfläche berühren. Der Boden, der von den übrigen Scheiben aufgeworfen wird, wird von der Außenscheibe in den Arbeitsbereich der Maschine zurückgefördert. Durch die Längeneinstellung des Haltearmes ist der Durchmesser der Außenscheibe gleich dem Durchmesser der übrigen Scheiben. Ein größerer Scheibendurchmesser ist besser, weil größere Scheiben mehr Bodenmaterial nach innen bewegen können. Durch die Längeneinstellung des Haltearmes kann die Außenscheibe optimal in einfacher Weise auf die Arbeitsbedingungen eingestellt werden und zwar so, dass die Scheibenunterkante der nach innen werfenden Außenscheibe gerade die Bodenoberfläche berührt.The invention has for its object to be able to adapt the operation of the discs of a disc harrow, especially outdoors, to the working conditions at different working depths of the disc harrow. This object is achieved by the characterizing feature of claim 1. As a result of this measure, the outer disc throwing inwards can be optimally adjusted to the working depth of the disc harrow. The inward throwing outer pane can be adjusted so that it just touches the ground with the lower edge of the pane. This means that the outer pane can only touch the ground surface at all adjustable working depths. The soil that is thrown up by the remaining disks is conveyed back from the outer disk into the working area of the machine. Due to the length adjustment of the holding arm, the diameter of the outer disc is equal to the diameter of the other discs. A larger disc diameter is better because larger discs can move more soil material inwards. By adjusting the length of the holding arm, the outer pane can be optimally adjusted to the working conditions in such a way that the lower pane edge of the inwardly projecting outer pane just touches the ground surface.
In einer Ausgestaltung der Erfindung ist vorgesehen, dass der Haltearm aus zwei Teilen besteht, die teleskopartig zueinander aus- und einziehbar und in unterschiedlichen Positionen zueinander einstellbar sind.In one embodiment of the invention, it is provided that the holding arm consists of two parts which can be telescopically extended and retracted relative to one another and can be adjusted to one another in different positions.
Der Haltearm kann im Querschnitt Winkelförmig oder als Quadrat- oder Rechteckrohr ausgebildet sein.The holding arm can have an angular cross section or a square or rectangular tube.
In einer anderen Ausgestaltung des Haltearms ist vorgesehen, dass der Haltearm gegenüber dem Querbalken längs verschieblich und einstellbar angeordnet ist. Weitere Einzelheiten der Erfindung sind der Beispielsbeschreibung und den Zeichnungen zu entnehmen. Hierbei zeigenIn another embodiment of the holding arm, it is provided that the holding arm is arranged to be longitudinally displaceable and adjustable relative to the crossbar. Further details of the invention can be found in the example description and the drawings. Show here

Die Scheibenegge weist einen Rahmen 1 auf, der die zumindest zwei Querbalken 2 miteinander verbindet. An dem Rahmen 1 ist ein rieht dargestellter Zentralrahmen angeordnet, der die beiden zueinander einklappbaren Scheibeneggenhälften trägt. An dem Zentralrahmen sind Kupplungselemente angeordnet, über die die Scheibenegge an einem Ackerschlepper anzukuppeln ist. Hinter der Scheibenegge sind an den Zentralrahmen oder dem' Rahmen 1 zusätzliche Bodenelemente, wie Walzen, oder Säorgane einer Sämaschine anzuordnen. An diesem Querbalken 2 sind jeweils mittels schräg nach hinten und nach unten weisender Haltearme 3 Scheiben 4 angeordnet. Die Scheiben 4 sind drehbar an diesen Haltearmen 3 befestigt. Die Scheiben 4 sind somit in zumindest zwei Querreihen 5 und 6 hintereinander angeordnet. Die Scheiben 4 sind mit einem Winkel zur Fahrtrichtung 7 schräg angestellt. Die eine Reihe 5 ist entgegengesetzt zur anderen 6 schräg angestellt, wie die Fig. 1 und Fig. 3 zeigen. Somit werfen die Scheiben 4 der vorderen Querreihen 5 den Boden nach rechts, wie durch die Pfeile 8 angedeutet, während die Scheiben 4 der hinteren Querreihe 6 den Boden nach links, wie durch die Pfeile 9 angedeutet, werfen. Die Scheiben 4 sind von hinten gesehen versetzt zueinander angeordnet, wie die Fig. 1 und Fig. 3 zeigen. Zumindest der Haltearm 3', der jeweils nach innen werfenden Außenscheibe 4', ist in seiner Länge einstellbar ausgebildet. Gemäß dem Ausführungsbeispiel nach den Fig. 1-6 besteht der Haltearm 3' , aus zwei Teilen 10 und 11, die teleskopartig auseinander und einziehbar und in unterschiedlichen Positionen einstellbar sind. Hierzu ist zumindest in dem einen Teil 10 des Haltearmes 3', jeweils zumindest ein Langloch 12 angeordnet, durch welches ein Bolzen 13 gesteckt ist, der mit dem anderen Teil des Haltearmes 11 verbunden ist. Um eine stabile Führung der beiden Teile 10 und 11 der Haltearmes 3' , zu erreichen, sind gemäß der Ausführungsbeispiele Fig. 1 bis Fig. 6 Teile 10 und 11 des Haltearmes 3 ' , im Querschnitt winkelförmig ausgebildet. Durch lösen der Bolzen 13 können die beiden Teile 10 und 11 des Haltearmes 3, teleskopartig zueinander verschoben werden, so dass die Außenscheibe 4', nach oben oder unten gegenüber dem Querbalken 2 zu verschieben ist. Somit kann die Scharunterkante 14 des nach innen werfende Außenscheibe 4' bei entsprechend gewählter Arbeitstiefe der übrigen Scheiben 4 der Scheibenegge so eingestellt werden, dass die nach innen werfende Außenscheibe 4', zumindest annähernd die Bodenoberfläche berührt. Dadurch wirft die Außenscheibe 4, das von den benachbarten Scheiben 4 nach außen geworfene Boden und Erdreich den übrigen Scheiben 4 in Richtung Scheibeneggenmitte zu. Die Außenscheibe 4' soll den Boden nicht in der Weise wie die übrigen Scheiben 4 der Scheibenegge bearbeiten sondern eine saubere Arbeitsbegrenzung der Scheibenegge schaffen. Da die Außenscheibe 4' im Gegensatz zum Stand der Technik den gleichen Durchmesser wie die übrigen Scheiben 4 aufweist und anderseits die Scharunterkante 14 um das Maß a höher als die Scharunterkante 15 der übrigen Scheiben 4 eingestellt, kann es einerseits sehr viel Bodenmaterial bewegen und andererseits einen sauberen Abschluss des Arbeitsbereiches der Scheibenegge im Außenbereich schaffen.The disc harrow has a frame 1 which connects the at least two crossbars 2 to one another. Arranged on the frame 1 is a central frame which carries the two disc harrow halves which can be folded towards one another. Coupling elements are arranged on the central frame, via which the disc harrow is to be coupled to an agricultural tractor. Behind the disc harrow 1 additional floor elements, such as rollers, or Säorgane are to be arranged a sowing machine to the central frame or the 'frame. On this crossbar 2 are each arranged 3 slices 4 by means of holding arms pointing obliquely backwards and downwards. The disks 4 are rotatably attached to these holding arms 3. The disks 4 are thus arranged in at least two transverse rows 5 and 6 one behind the other. The discs 4 are inclined at an angle to the direction of travel 7. One row 5 is set at an angle to the other 6, as shown in FIGS. 1 and 3. Thus, the disks 4 of the front transverse rows 5 throw the floor to the right, as indicated by the arrows 8, while the disks 4 of the rear transverse row 6 throw the floor to the left, as indicated by the arrows 9. The disks 4 are arranged offset from one another as seen from the rear, as shown in FIGS. 1 and 3. At least the length of the holding arm 3 ', of the outer disc 4' throwing inwards, is adjustable. According to the embodiment of FIGS. 1-6, the holding arm 3 'consists of two parts 10 and 11, which are telescopically apart and retractable and adjustable in different positions. For this purpose, at least one elongated hole 12 is arranged at least in one part 10 of the holding arm 3 ', through which a bolt 13 is inserted, which is connected to the other part of the holding arm 11. In order to achieve stable guidance of the two parts 10 and 11 of the holding arms 3 ', parts 10 and 11 of the holding arm 3' are of angular cross-section in accordance with the exemplary embodiments in FIGS. 1 to 6. By loosening the bolts 13, the two parts 10 and 11 of the holding arm 3 can be telescopically displaced relative to one another, so that the outer pane 4 'can be displaced upwards or downwards relative to the crossbar 2. Thus, the lower edge 14 of the coulter of the outer disc 4 'throwing inwards can be adjusted with a correspondingly selected working depth of the remaining discs 4 of the disc harrow so that the outer disc 4' throwing inwards, at least approximately Touches the ground surface. As a result, the outer disc 4, the soil and soil thrown outward by the adjacent discs 4, throws the remaining discs 4 towards the center of the disc harrow. The outer disc 4 'should not work the soil in the same way as the other discs 4 of the disc harrow, but should create a clean working limitation of the disc harrow. Since the outer disc 4 ', in contrast to the prior art, has the same diameter as the other discs 4 and on the other hand the lower edge 14 of the share is set higher by a dimension than the lower edge 15 of the other discs 4, it can move a lot of soil material on the one hand and on the other hand Create a clean finish to the working area of the disc harrow outdoors.
Anstelle einer winkelförmigen Querschnittsausbildung des Haltearmes 3 ist es auch möglich den Haltearm als Quadratoder Rechteckrohr auszubilden.Instead of an angular cross-sectional configuration of the holding arm 3, it is also possible to design the holding arm as a square or rectangular tube.
Das Ausführungsbeispiel nach Fig. 7 unterscheidet sich von den Fig. 1 bis Fig. 6 dadurch, dass der Haltearm 16 nicht teleskopartig aus zwei zueinander verschiebbaren Teile besteht, sondern der Haltearm 16 ist gegenüber dem Querbalken 2 längsverschieblich und einstellbar angeordnet. The exemplary embodiment according to FIG. 7 differs from FIGS. 1 to 6 in that the holding arm 16 does not consist of two parts that can be displaced relative to one another in a telescopic manner, but rather the holding arm 16 is arranged so as to be longitudinally displaceable and adjustable relative to the crossbar 2.
