SchwenkpfiugSwivel plow
B e s c h r e i b u n g :Description :
Die Erfindung betrifft einen Schwenkpflug mit einem Hauptrahmen in Form eines geraden Pflugbaums, an dem über seine axiale Länge' verteilt mehrere Pflugkörper in axialem Abstand zueinander befestigt sind. Solche Pflüge besitzen einen Anbaurahmen, der an dem Dreipunktgestänge des Schleppers be¬ festigt ist und der in Fahrtrichtung in einem Abstand hinter dem Schlepper eine - 2The invention relates to a pivot plow comprising a main frame in the form of a straight plow beam, 'distributed to the axial along its length a plurality of plow body at an axial distance from one another are fixed. Such plows have an attachment frame which is attached to the three-point linkage of the tractor and which is one behind the tractor at a distance in the direction of travel - 2nd
in den Arbeitsstellungen des Pfluges im wesentlichen vertikale Schwenkachse auf¬ weist, auf der der Pflugbaum als zwei¬ armiger Schwenkhebel mit einem kürzeren Kopfteil und einem längeren Schwanzteil im wesentlichen horizontal schwenkbar gelagert ist, wobei der Pflugbaum mittels hydraulischer Schwenkzylinder verschwenkt wird, die einerseits am Anbaurahmen und andererseits an einem sogenannten Anlenk- punkt am Pflugbaum angelenkt sind.in the working positions of the plow has essentially a vertical pivot axis on which the plow boom, as a two-armed pivot lever with a shorter head part and a longer tail part, is pivoted essentially horizontally, the plow boom being pivoted by means of hydraulic pivot cylinders which, on the one hand, on the mounting frame and on the other hand are articulated at a so-called articulation point on the plow tree.
Die Voraussetzung für eine gute und saubere Pflugarbeit ist eine genaue Abstimmung des Pfluges auf den jeweiligen Schlepper. Unter anderem muß auch eine genaue Anpassung der Schnittbreite des vorlaufenden ersten Pflug¬ körpers an das Spurinnenmaß des jeweiligen Schleppers vorgenommen werden. Das ist als sogenannte Einstellung der Vorderfurchenbreite bekannt, die grundsätzlich bei jedem Schlepper¬ wechsel mit geänderten Spurinnenmaßen vorge¬ nommen werden muß. Aber auch ohne Schlepper¬ wechsel muß die Einstellung der Vorderfurchen¬ breite häufig dann korrigiert werden, wenn an Hanglagen gepflügt wird. Auch das ist dem Fachmann bekannt.The prerequisite for good and clean plow work is an exact match of the plow to the respective tractor. Among other things, a precise adaptation of the cutting width of the leading first plow body to the internal track dimension of the respective tractor must also be carried out. This is known as the so-called adjustment of the front furrow width, which in principle has to be carried out each time the tractor is changed with changed internal track dimensions. But even without changing the tractor, the setting of the front furrow width often has to be corrected when plowing on slopes. This is also known to the person skilled in the art.
Diese Vorderfurchenbreiteneinstellung wird bei bekannten Schwenkpflügen dadurch be¬ wirkt, daß der Anbaurahmen, der den Pflug¬ baum mit den Pflugkörpern trägt, in seiner Gesamtheit zu der einen oder anderen Seite des Schleppers versetzt wird, indem die UnterlenkerIn the case of known swivel plows, this front furrow width setting is effected in that the mounting frame which carries the plow tree with the plow bodies is in its The whole is moved to one or the other side of the tractor by the lower link
•Ά des Dreipunktgestänges des Schleppers nach rechts oder links gegen einen Anschlag gedrückt werden. Dadurch ändert sich natürlich auch die seitliche Winkelstellung des Oberlenkers des Dreipunktgestänges, wodurch sich eine schlechtere Seitenführung des Pfluges ergeben kann.• Ά of the tractor's three-point linkage are pressed to the right or left against a stop. Of course, this also changes the lateral angular position of the top link of the three-point linkage, which can result in poorer lateral guidance of the plow.
Weiterhin ist es nachteilig, daß diese seit¬ liche Versetzung des Anbaurahmens bzw. des Pfluges in seiner Gesamtheit stets am Ende einer Furche von der einen auf die andere Seite des Schleppers erfolgen muß, wodurch die von der Versetzung betroffenen Gelenkteile einem erhöhten Verschleiß unterliegen.It is also disadvantageous that this lateral displacement of the mounting frame or of the plow in its entirety must always take place at the end of a furrow from one side to the other of the tractor, as a result of which the joint parts affected by the displacement are subject to increased wear.
Aufgabe der Erfindung ist es, für einen Schwenk¬ pflug des einleitend definierten Typs eine verbesserte Einstellung der Vorderfurchenbreite vorzuschlagen.The object of the invention is to propose an improved adjustment of the front furrow width for a swivel plow of the type defined in the introduction.
Diese Aufgabe wird dadurch gelöst, daß der Pflug¬ baum mitsamt den an ihm befestigten Pflugkörpern in Richtung seiner axialen Längserstreckung in dem Anlenkrahmen verschiebbar gelagert ist und zwar relativ zur Schwenkachse und relativ zu den Anlenkpunkten der Schwenkzylinder am PflugbauThis object is achieved in that the plow tree, together with the plow bodies attached to it, is mounted displaceably in the direction of its axial longitudinal extent in the articulation frame, namely relative to the pivot axis and relative to the articulation points of the pivot cylinders on the plow construction
Ein wesentlicher Vorteil des neuen Schwenk¬ pfluges ist zunächst dadurch gegeben, daß dessen Anbaurahmen stets mittig zum Schlepper an dessen Dreipunktgestänge angelenkt ist und bleibt, d.h. daß sich der Anbaurahmen bei der Einstellung der Vorderfurchenbreite nicht aus seiner mittigen Anbauposition am Schlepper herausbewegt.A major advantage of the new swivel plow is given first by the fact that its mounting frame is and is always articulated in the center of the tractor on its three-point linkage, that is to say that the mounting frame is adjusted during adjustment the front furrow width does not move out of its central mounting position on the tractor.
Die Einstellung der Vorderfurchenbreite wird allein durch die axiale Verschiebung des Pflug¬ baumes bewirkt. Damit ist zugleich gewährleistet, daß diese axiale Verschiebung immer für beide Schwenkpositionen des Pflugbaumes gilt, so daß eine einmalige Einstellung der Vorderfurchen¬ breite für beide Arbeitspositionen des Pfluges ausreichend ist, in denen der Kopfteil des Pflugbaumes mit dem ersten vorlaufenden Pflug¬ körper entweder nahe dem rechten oder nahe dem linken Hinterrad des Schleppers steht. Für den Landwirt, der im wesentlichen auf ebenen Flächen pflügt, ist dies ein entscheidender Vorteil, da er die einmal eingestellte Vorderfurchenbreite beibehalten kann unabhängig davon, mit welcher Seite der Pflug zum gepflügten Feld arbeitet.The adjustment of the front furrow width is effected solely by the axial displacement of the plow tree. This also ensures that this axial displacement always applies to both swivel positions of the plow tree, so that a single adjustment of the front furrow width is sufficient for both working positions of the plow, in which the head part of the plow tree with the first leading plow body is either close to that right or near the left rear wheel of the tractor. This is a decisive advantage for the farmer who plows essentially on flat surfaces, since he can maintain the set front furrow width regardless of which side the plow works with the plowed field.
Eine besonders vorteilhafte Ausführungsform der Erfindung sieht vor, daß die axiale Ver¬ schiebbarkeit des Pflugbaumes durch zwei teleskopartig ineinander gesteckte Rohrprofile gegeben ist derart, daß der Pflugbaum als Außen¬ rohr auf dem Innenrohr aufgeschoben ist, wobei das Innenrohr auf der Schwenkachse des Anbau¬ rahmens axial unverschiebbar gelagert ist und die Anlenkpunkte für die Schwenkzylinder auf¬ weist, wohingegen das Außenrohr langlochähnliche Durchbrüche für die Schwenkachse und die Anlenk¬ punkte besitzt, um das Verschieben des Außenrohrs auf dem Innenrohr zu ermöglichen.A particularly advantageous embodiment of the invention provides that the plow boom can be axially displaced by two telescopically inserted tubular profiles such that the plow boom is pushed onto the inner tube as an outer tube, the inner tube being on the pivot axis of the mounting frame is axially immovable and has the articulation points for the swivel cylinders, whereas the outer tube has elongated perforations for the swivel axis and the articulation points for the displacement of the outer tube to allow on the inner tube.
Es steht außer Zweifel, daß eine solche ver¬ schiebbare Außenrohr-Lagerung auf einem Innen¬ rohr sehr stabil und störunanfäl 1 ig ist. Alternativ kann der Pflugbaum auch in Gleit¬ schuhen verschiebbar gelagert sein, die Be¬ standteil einer um die Schwenkachse verschwenk¬ baren Konstruktionen sind, wobei die Schwenk¬ zylinder dann an diese Konstruktion angreifen. Bei einem solchen in Gleitschuhen gelagerten Pflugbaum ist der Pflugbaum in beliebiger Weise ausführbar, da ein Rohrprofil nicht erforderlich i st .There is no doubt that such a displaceable outer tube mounting on an inner tube is very stable and prone to failure. Alternatively, the plow tree can also be slidably mounted in sliding shoes which are part of a construction which can be pivoted about the pivot axis, the pivot cylinders then engaging this construction. In such a plow tree stored in sliding shoes, the plow tree can be carried out in any manner, since a tubular profile is not required.
Die axiale Verschiebung des Pflugbaumes kann per Hand oder automatisch erfolgen und zwar mittels einer Stellvorrichtung, die einerseits an dem Pflugbaum und andererseits an einem ortsfesten Punkt der Rahmenkonstruktion ange¬ lenkt ist. Bei einem Pflugbaum, der als Außen¬ rohr auf einem Innenrohr aufgeschoben ist, sieht eine zweckmäßige Ausgestaltung der Erfindung vor, daß die Stellvorrichtung in Form eines Hydraulik¬ zylinders im Inneren des Außenrohrs und/oder des Innenrohrs angeordnet ist.The axial displacement of the plow tree can be carried out manually or automatically by means of an adjusting device which is articulated on the one hand on the plow tree and on the other hand at a fixed point on the frame construction. In the case of a plow tree which is pushed onto an inner tube as an outer tube, an expedient embodiment of the invention provides that the actuating device is arranged in the form of a hydraulic cylinder in the interior of the outer tube and / or the inner tube.
Bei einem Schwenkpflug nach der Erfindung kann weiterhin vorgesehen sein, daß der axial ver¬ schiebbare Pflugbaum einen Stoßdämpfer auf¬ weist, der immer dann in Aktion tritt, wenn die an dem Pflugbaum befestigten Pflugkörper gegen - 6 -In the case of a swivel plow according to the invention it can further be provided that the axially displaceable plow tree has a shock absorber which always comes into action when the plow bodies attached to the plow tree counteract - 6 -
einen Stein oder ein anderes Hinternis im Feld anlaufen. Ein solcher Stoßdampfer schützt damit die dem Stoßdämpfer nachge¬ schalteten Bauteile des Pfluges und auch den Schlepper gegen ruckartige Belastungenhit a stone or other obstacle in the field. Such a shock absorber thus protects the plow components connected downstream of the shock absorber and also the tractor against jerky loads
Ist die Stellvorrichtung für das axiale Ver¬ schieben des Pflugbaumes als Hydraulikzylinder in den hohlen Pflugbaum eingebaut, dann sieht eine besonders vorteilhafte Ausführungsform der Erfindung vor, daß eine hydraulische Sto߬ dämpfervorrichtung in das Hydrauliksystem des Hydraulikzylinders integriert ist.If the adjusting device for the axial displacement of the plow tree is installed as a hydraulic cylinder in the hollow plow tree, then a particularly advantageous embodiment of the invention provides that a hydraulic shock absorber device is integrated in the hydraulic system of the hydraulic cylinder.
Als zweckmäßige Ausgestaltung kann der neue Schwenkpflug auch mit einer Anzeigevorrichtung versehen sein, die die jeweilige axiale Ver- schiebepositioπ des Pflugbaumes anzeigt.As an expedient embodiment, the new swivel plow can also be provided with a display device which indicates the respective axial displacement position of the plow tree.
Nachfolgend wir ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen näher be¬ schrieben. Es zeigen:An exemplary embodiment of the invention is described in more detail below with reference to the drawings. Show it:
Fig. 1 die Draufsicht auf einen er¬ findungsgemäßen Schwenkpflug,1 is a top view of a swivel plow according to the invention,
Fig. 2 die Seitenansicht des Pflugbaumes mit den Pflugkörpern des Schwenk¬ pfluges nach Fig. 1.FIG. 2 shows the side view of the plow tree with the plow bodies of the swivel plow according to FIG. 1.
Aus Fig. 1 ist ersichtlich, daß die Rahmen¬ konstruktion des neuen Schwenkpfluges einen Anbaurahmen 3 und einen Hauptrahmen in Form eines geraden Pflugbaums 4 aufweist.From Fig. 1 it can be seen that the frame construction of the new swivel plow has a mounting frame 3 and a main frame in shape of a straight plow tree 4.
Wie Fig. 2 zeigt, sind an dem Pflugbaum 4 über seine axiale Länge verteilt mehrere Pflugkörper 5 in einem axialen Abstand zu¬ einander befestigt. Die Pflugkörper sind achssymmetrisch unter dem Pflugbaum ange¬ ordnet und besitzen jeweils seitliche An¬ lageflächen 6, die beim Pflügen an der Furchenkante entlangstreichen. Solche Pflugkörper sind in ihrem grundsätzlichen Aufbau bekannt und bedürfen deshalb keiner weiteren Beschreibung.As shown in FIG. 2, a plurality of plow bodies 5 are attached to the plow tree 4 distributed over its axial length at an axial distance from one another. The plow bodies are arranged axially symmetrically under the plow tree and each have lateral contact surfaces 6 which sweep along the furrow edge during plowing. The basic structure of such plow bodies is known and therefore does not require any further description.
Der Anbaurahmen 3 besitzt eine Unterlenker¬ traverse 7 an der die beiden Aufnahmen 8 die beiden Unterlenker des Dreipunktgestänges eines Schleppers aufnehmen. Der Oberlenker des Dreipunktgestänges ist an der oberen Auf¬ nahme 9 des Rahmenbockes 10 angelenkt, wie dies bekannt und üblich ist.The mounting frame 3 has a lower link traverse 7 on which the two receptacles 8 receive the two lower links of the three-point linkage of a tractor. The upper link of the three-point linkage is articulated on the upper receptacle 9 of the frame bracket 10, as is known and customary.
Die hintere Quertraverse 11 des Anbaurahmens besteht aus zwei parallel übereinander- liegenden Querträgern, die jeweils ein Ende der Schwenkachse 12 fixieren, die sich zwischen diesen beiden Querträgern erstreckt.The rear crossmember 11 of the mounting frame consists of two crossmembers lying one above the other in parallel, each of which fixes one end of the pivot axis 12 which extends between these two crossmembers.
Auf der Schwenkachse 12 ist der Pflugbaum 4 als zweiarmiger Schwenkhebel mit einem kürzeren Kopfteil und einem längeren Schwanzteil schwenk' bar gelagert. Der Schwanzteil wird durch das Stützrad 13 gestützt und der Kopfteil über¬ greift mit einem oberen und einem unteren Gleitlager 14 (vergl. Fig. 2) ein Führungs¬ blech 15, dessen Führungskaπte kreisförmig um die Schwenkachse 12 ausgebildet ist.On the swivel axis 12, the plow boom 4 is swiveled as a two-armed swivel lever with a shorter head part and a longer tail part. stored in cash. The tail part is supported by the support wheel 13 and the head part overlaps with an upper and a lower slide bearing 14 (see FIG. 2) a guide plate 15, the guide edge of which is circular about the pivot axis 12.
Die Verschwenkbewegung des Pflugbaumes 4 von seiner einen Arbeitspostion, die in Fig. 1 dargestellt ist, in die entgegengesetzte Arbeitspostion wird vermittels der hydrau- lichen Schwenkzylinder 16 vorgenommen, die einerseits an der hinteren Quertraverse 11 des Anbaurahmens und andererseits an soge¬ nannten Anlenkpunkten 17 angelenkt sind.The pivoting movement of the plow tree 4 from its one working position, which is shown in FIG. 1, into the opposite working position is carried out by means of the hydraulic pivoting cylinder 16, which is articulated on the one hand on the rear crossbar 11 of the mounting frame and on the other hand at so-called articulation points 17 are.
Gemäß der Erfindung ist der Pflugbaum 4 als Vierkant-Außenrohr ausgebildet, das auf ein Vierkant-Innenrohr 18 aufgeschoben ist, wo¬ bei das Innenrohr 18 an seinem Kopfende die beiden Gleitlager 14 besitzt, die die Führungs¬ kante des Führungsbleches 15 ergreifen.According to the invention, the plow tree 4 is designed as a square outer tube which is pushed onto a square inner tube 18, the inner tube 18 having at its head end the two slide bearings 14 which grip the guide edge of the guide plate 15.
Das Innenrohr ist auf der Schwenkachse 12 schwenkbar, aber unverschiebbar gelagert, wie dies die strich-punktierte Mittellinie 19 in Fig. 2 verdeutlicht. Auch sind die Anlenk- punkte 17 der Schwenkzylinder 16 an dem Innen¬ rohr 18 angeschweißt, wie dies ebenfalls aus Fig. 2 am besten entnehmbar ist.The inner tube is pivotally but non-displaceably mounted on the pivot axis 12, as illustrated by the dash-dotted center line 19 in FIG. 2. The articulation points 17 of the swivel cylinders 16 are also welded to the inner tube 18, as can also best be seen from FIG. 2.
Das auf das Innenrohr 18 aufgeschobene Außen¬ rohr 4, das den Pflugbaum bildet, besitzt langlochähnl iche Durchbrüche 20 (im Bereich der Schwenkachse 12, siehe Fig. 1) und 21 (im Bereich der Anlenkpunkte 17, siehe Fig. 2), um das Verschieben des Außenrohrs 4 auf dem Innenrohr 18 zu ermöglichen.The outer tube 4, which is pushed onto the inner tube 18 and forms the plow tree, has slot-like openings 20 (in the area of the pivot axis 12, see FIG. 1) and 21 (in the area of the articulation points 17, see FIG. 2) to enable the outer tube 4 to be displaced on the inner tube 18.
Die axiale Verschiebung des Außenrohrs auf dem Innenrohr erfolgt mittels einer Stell¬ vorrichtung, die in dem dargestellten Aus¬ führungsbeispiel ein Hydraulikzylinder 22 ist, der im Inneren des Außenrohrs 4 posi¬ tioniert und mit seinem einen Ende an dem Außenrohr befestigt ist. Das andere Ende des Hydraulikzylinders, d.h. das kolben- stangenseitige Ende des Hydraulikzylinders greift etwas in das Innenrohr 18 ein und ist an dem Innenrohr 18 befestigt, wie dies Fig. 2 am besten zeigt. Somit wird ver¬ mittels des Hydraulikzylinders 22, der auch vom Schleppersitz aus betätigt werden kann, eine axiale Verschiebung des Pflugbaumes 4 auf dem Innenrohr 18 (und damit relativ zur Schwenkachse 12 und den beiden Anlenkpunkten 17 der Schwenkzylinder 16) vorgenommen und zwar jeweils in der Größenordnung, wie sie für eine genaue Einstellung der Vorderfurchen' breite des Pfluges erforderlich ist. The axial displacement of the outer tube on the inner tube takes place by means of an actuating device, which in the exemplary embodiment shown is a hydraulic cylinder 22 which is positioned in the interior of the outer tube 4 and is fastened at one end to the outer tube. The other end of the hydraulic cylinder, i.e. the end of the hydraulic cylinder on the piston rod side engages somewhat in the inner tube 18 and is fastened to the inner tube 18, as best shown in FIG. 2. Thus, by means of the hydraulic cylinder 22, which can also be operated from the tractor seat, the plow tree 4 is axially displaced on the inner tube 18 (and thus relative to the pivot axis 12 and the two pivot points 17 of the pivot cylinder 16), in each case in the The order of magnitude required for precise adjustment of the front furrow width of the plow.
