Description
Werkzeugträger für Bodenbearbeitungs- und Bodenbehandlungsmaschinen Tool carriers for tillage and soil treatment machines
Die Erfindung betrifft ein Gerät nach dem Oberbegriff des Anspruches 1 , insbesondere einen Werkzeugträger, der vorzugsweise für Bodenbearbeitungs- und Sämaschinen einsetzbar ist.The invention relates to a device according to the preamble of claim 1, in particular a tool carrier, which can preferably be used for tillage and sowing machines.
Mit zunehmender Größe der zu bearbeitenden landwirtschaftlichen Flächen wächst die Notwendigkeit, Maschinen mit immer größeren Arbeitsbreiten einzusetzen. Dies gilt sowohl für Bodenbearbeitungsgeräte, wie z.B. Grubber, Eggen und dergl. als auch für Bodenbehandlungsgeräte, wie z.B. Spritzgeräte, Sävorrichtungen und dergl.. Im Zuge dieser Entwicklung werden Bearbeitungsbreiten von ca. 12 m und darüber angestrebt. Um solche überbreiten Maschinen auf Straßen bewegen zu können, darf die maximale Straßenfahrtbreite 3 m und die maximale Straßenfahrthöhe ca. 4 m nicht überschreiten.With the increasing size of the agricultural areas to be cultivated, the need to use machines with ever larger working widths increases. This applies to both tillage equipment, e.g. Cultivators, harrows and the like as well as for soil treatment devices such as Spraying devices, sowing devices and the like. In the course of this development, processing widths of approx. 12 m and above are aimed for. In order to be able to move such oversized machines on roads, the maximum road travel width must not exceed 3 m and the maximum road ride height approx. 4 m.
Aufgabe der Erfindung ist es deshalb, Werkzeugträger für derartige Maschinen vorzuschlagen, die einerseits eine Gesamtarbeitsbreite in der Größenordnung von 12 m haben und die für Straßenfahrt zu einer zulässigen Breite von maximal 3 m und einer zulässigen Höhe von maximal 4 m zusammenlegbar bzw. zusammenklappbar sind. Des weiteren ist Aufgabe der Erfindung, den Werkzeugträger mit den Werkzeugen etwa parallel zum Boden anzuheben und damit die Werkzeuge außer Eingriff mit dem Boden zu bringen.The object of the invention is therefore to propose tool carriers for such machines which on the one hand have a total working width of the order of magnitude of 12 m and which can be folded or collapsed for road travel to a maximum width of 3 m and a maximum height of 4 m. Furthermore, it is an object of the invention to raise the tool carrier with the tools approximately parallel to the floor and thus to bring the tools out of engagement with the floor.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die beiden schwenkbar am Mittelträger befestigten Verlängerungsträger im Abstand von den Enden des Mittelträgers angelenkt sind, die Werkzeuge des Verlängerungsträgers im hochgeschwenkten, vertikalen Zustand (Straßenfahrt) mit der Außenbegrenzung des Mittelträgers bündig abschließen, wobei die Werkzeuge horizontal nach außen gerichtet sind, und die Verlängerungsträger am äußeren Ende jeweils eine Schwenkstelle zur Aufnahme eines Klappträgers aufweisen, der gegenüber den Verlängerungsträgem um 180° in die Fahrtposition klappbar ist, und die Werkzeuge aufeinander zu nach innen gerichtet sind. Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche.According to the invention, this object is achieved in that the two extension beams pivotally attached to the central beam are articulated at a distance from the ends of the central beam, the tools of the extension beam in the swung-up, vertical state (road travel) are flush with the outer limit of the central beam, the tools are directed horizontally outwards, and the extension beams at the outer end each have a pivot point for receiving a Have folding carrier, which can be folded 180 ° into the driving position relative to the extension beams, and the tools are directed towards each other inwards. Further features of the invention are the subject of the dependent claims.
Der Werkzeugträger nach der Erfindung weist in einer bevorzugten Ausführungsform einen einteiligen horizontalen Mittelträger von ca. 3 m Breite auf, an dem nach abwärts stehende Werkzeugelemente mit einer Höhe von z.B. ca. 600 mm befestigt sind (Säschare, Grubberelemente oder dergl.). Die Außenenden des Mittelträgers bestimmen dabei die Gesamtbreite des Werkzeugträgers in Fahrtrichtung. Am Mittelträger ist im Abstand der beiden Endbereiche nach innen jeweils ein Verlängerungsträger gelenkig gelagert, der aus der vertikalen Straßenposition in die horizontale Arbeitsposition um 90° verschwenkt werden kann. Die Länge dieser Verlängerungsträger ist ca. 27-3 m, und die Anlenkstelle dieser Verlängerungsträger an dem horizontalen Mittelträger ist etwa 0,6 m von der Außenbegrenzung der Mittelträgerenden nach innen angeordnet. Am äußeren Ende der Verlängerungsträger ist jeweils ein Klappträger ange-lenkt, der um 180° verschwenkbar ist, in Fahrtstellung also parallel zum jeweiligen Verlängerungsträger in vertikaler Position verläuft und eine Länge von ca. 3,2 m hat. Bei Straßenfahrt und eingeklapptem Zustand nehmen die Werkzeuge des Verlängerungs-trägers eine horizontale Lage ein und sind nach außen gerichtet, während die Werkzeugelemente des Klappträgers eine horizontale Lage einnehmen und nach innen aufeinander zu gerichtet sind, so daß die Werkzeuge der beiden Klappträger unmittelbar einander gegenüberstehen.In a preferred embodiment, the tool carrier according to the invention has a one-piece horizontal center carrier of approximately 3 m in width, to which downwardly extending tool elements with a height of approximately 600 mm, for example, are attached (coulters, cultivator elements or the like). The outer ends of the center carrier determine the overall width of the tool carrier in the direction of travel. An extension bracket is articulated on the center bracket, at a distance from the two end areas, and can be pivoted 90 ° from the vertical road position into the horizontal working position. The length of these extension beams is approx. 2 7 -3 m, and the articulation point of these extension beams on the horizontal central beam is arranged approximately 0.6 m inwards from the outer boundary of the central beam ends. At the outer end of the extension bracket, a folding bracket is articulated, which can be swiveled through 180 °, i.e. in the driving position runs parallel to the respective extension bracket in a vertical position and has a length of approx. When driving on the road and when folded, the tools of the extension bracket assume a horizontal position and are directed outwards, while the tool elements of the folding bracket assume a horizontal position and are directed towards each other inwards, so that the tools of the two folding brackets are directly opposite one another.
Entscheidend für eine optimale Lösung ist, daß die am Mittelträger gelenkig gelagerten Verlängerungsträger an einer optimalen Stelle innerhalb des Mittelträgers gelagert sind, um eine besonders günstige Raumausnützung zu erzielen. Damit eine maximale Breite der Gesamtmaschine für Straßenfahrt von 3,0 m beibehalten werden kann, erfolgt die Anlenkung des Verlängerungsteils in einem Abstand von ca. 0,6 m von der Außenkante des Mittelträgers, so daß in hochgeklapptem Zustand die Außenbegrenzung der Werk- zeuge des Verlängerungsträgers innerhalb der für Straßenfahrt zugelassenen Breite liegt und insgesamt eine optimierte Abstimmung der einzelnen Träger mit den Werkzeugen aufeinander erzielt werden kann.It is crucial for an optimal solution that the extension beams articulated on the central beam are mounted at an optimal location within the central beam in order to achieve a particularly favorable use of space. So that a maximum width of 3.0 m for road travel can be maintained, the extension part is articulated at a distance of approx. 0.6 m from the outer edge of the central girder, so that when folded up, the outer limit of the factory witness of the extension beam is within the approved width for road travel and overall an optimized coordination of the individual beams with the tools can be achieved.
Bei einer speziellen Ausführungsform der Erfindung ist die Maschine eine vierreihige Maschine, die eine (in Fahrtrichtung) vordere Zinkenreihe und eine hintere Zinkenreihe (bzw. Werkzeugelementreihe) aufweist. Zwischen der zweiten und der dritten Reihe von Werkzeug-elementen ist jeweils ein größerer Abstand vorgesehen als zwischen der ersten und zweiten sowie der dritten und vierten Reihe, damit die Tiefenführungsvorrichtungen und die Transporträder besonders zweckmäßig untergebracht werden können, wobei der Abstand der Werkzeugelemente der zweiten und der dritten Werkzeugelementreihe mindestens dem Raddurchmesser der Transporträder entspricht und auf diese Weise beim Absenken des Werkzeugträgers für die Bodenbehandlung ein genügender Freiraum für die Tiefenführungen und die Transporträder erzielt wird.In a special embodiment of the invention, the machine is a four-row machine which has a front row of tines (in the direction of travel) and a rear row of tines (or row of tool elements). Between the second and the third row of tool elements there is a greater distance than between the first and second as well as the third and fourth row, so that the depth guiding devices and the transport wheels can be accommodated particularly expediently, the distance between the tool elements of the second and the third row of tool elements corresponds at least to the wheel diameter of the transport wheels and in this way sufficient clearance for the depth guides and the transport wheels is achieved when lowering the tool carrier for the soil treatment.
Die Werkzeugelemente der in Fahrtrichtung hintereinander angeordneten Werkzeugelementreihen sind in Fahrtrichtung gegeneinander versetzt. Dabei ist es besonders zweckmäßig, in der Längsmittenachse des Werkzeugträgers ein Werkzeugelement vorzusehen und die anderen Werkzeugelemente der unterschiedlichen Reihen von Werkzeugelementen beidseitig der Mittenlängsachse nach links und rechts symmetrisch anzuordnen.The tool elements of the rows of tool elements arranged one behind the other in the direction of travel are offset from one another in the direction of travel. It is particularly expedient to provide a tool element in the longitudinal center axis of the tool carrier and to arrange the other tool elements of the different rows of tool elements on both sides of the central longitudinal axis symmetrically to the left and right.
In weiterer Ausgestaltung der Erfindung ist in der Mittenlängsachse eine Schubstangenanordnung vorgesehen, mit der der Werkzeugträgerrahmen über die Deichsel und die Oberlenker parallel hochgehoben wird. Das Ausheben bzw. das parallele Anheben des Werkzeugträgers erfolgt mit Hilfe von Arbeitszylindern, die an Trägerarmen angreifen, welche die Tandem-Laufräder aufnehmen, und welche an einem sich über die gesamte Maschinenbreite erstreckenden Torsionsrohr fest verbunden sind. Durch das Betätigen der Arbeitszylinder wird das Torsionsrohr gedreht. Am Torsionsrohr ist ein Flansch starr befestigt, über den das Ausmaß der Drehbewegung des Torsionsrohres in eine entsprechende Längsbewegung der Schubstange übertragen wird, die die Deichsel des Werkzeugträgers verschiebt. Diese Schiebebewegung wird auf den Oberlenker übertragen, der eine Schwenkbewegung ausführt, um einem Kippen des Rahmens des Werkzeugträgers entgegen zu wirken und ein paralles Anheben des Rahmens des Werkzeugträgers zu ermöglichen.In a further embodiment of the invention, a push rod arrangement is provided in the central longitudinal axis, with which the tool carrier frame is lifted up in parallel over the drawbar and the upper links. The tool carrier is lifted out or raised in parallel with the aid of working cylinders which act on carrier arms which receive the tandem impellers and which are firmly connected to a torsion tube which extends over the entire width of the machine. The torsion tube is rotated by actuating the working cylinders. A flange is rigid on the torsion tube attached, via which the extent of the rotational movement of the torsion tube is transferred into a corresponding longitudinal movement of the push rod, which shifts the drawbar of the tool holder. This sliding movement is transmitted to the upper link, which carries out a pivoting movement in order to counteract a tilting of the frame of the tool carrier and to enable the frame of the tool carrier to be lifted in parallel.

Der Werkzeugträgerrahmen besteht aus einem Mittelträger 1 mit Außenenden 2 und 3, der Werkzeugelemente 4, 5, 6 mit entsprechenden Werkzeughaltern aufnimmt, sowie zwei im Mittelträger 1 bei 7 und 8 schwenkbar gelagerten Verlängerungsträgern 9, 10 mit Werkzeugelementen 1 1, 12, 13, 14. Die Lagerstellen der Verlängerungsträger 9, 10 sind von den Außenenden 2,3 nach innen aufeinander zu beabstandet. Die Verlängerungsträger 9 und 10 nehmen über am äußeren Ende angeordnete Schwenklager 15 und 16 jeweils einen Klappträger 1 7, 18 auf, der nach innen gerichtete Werkzeugelemente 19, 20, bzw. 21 , 22 trägt.The tool carrier frame consists of a center carrier 1 with outer ends 2 and 3, which receives tool elements 4, 5, 6 with corresponding tool holders, and two extension carriers 9, 10 pivotably mounted in the center carrier 1 at 7 and 8 with tool elements 1 1, 12, 13, 14 The bearing points of the extension beams 9, 10 are spaced apart towards one another from the outer ends 2, 3. The extension brackets 9 and 10 each receive a folding bracket 17, 18, which carries inwardly directed tool elements 19, 20 and 21, 22, respectively, via swivel bearings 15 and 16 arranged at the outer end.
Der Abstand, um den die Lagerstelle 7, 8 vom Außenende 2, 3 des Mittelträgers 1 nach innen verlegt ist, entspricht der Strecke, die die Werkzeugelemente 4, 5, 6 sich vom Mittelträger 1 nach unten erstrecken, in der Praxis des Ausführungsbeispieles 0,6 cm (Darstellung nach Fig. 2), so daß in geklapptem Zustand die nach außen gerichteten Werkzeugelemente bündig mit den Enden 2, 3 des Mittelteiles abschließen.The distance by which the bearing point 7, 8 is moved inwards from the outer end 2, 3 of the central carrier 1 corresponds to the distance that the tool elements 4, 5, 6 are from Extend center support 1 downwards, in the practice of the exemplary embodiment 0.6 cm (illustration according to FIG. 2), so that in the folded state the outwardly directed tool elements are flush with the ends 2, 3 of the middle part.
Die Verlängerungsträger 9, 10 werden aus der Arbeitsstellung nach Fig. 1 in die eingeklappte Stellung (Fahrtstellung) nach Fig. 2 um 90° hochgeklappt, nachdem die Klappträger 1 7, 18 über Schwenklager 1 5, 16 um 180° gegen die Verlängerungsträger 9, 10 geklappt worden sind, so daß die Klappträger und die Verlängerungsträger aneinander anschließen und die Werkzeugelemente 1 1 , 12, 13, 14 waagrecht nach außen stehen, während die Werkzeugelemente 19, 20, 21 , 22 waagrecht nach innen aufeinander zu verlaufen und die freien Werkzeugenden sich unmittelbar gegenüberstehen.The extension supports 9, 10 are folded up from the working position according to FIG. 1 into the folded-in position (driving position) according to FIG. 2 by 90 ° after the folding supports 1 7, 18 via pivot bearings 15, 16 through 180 ° against the extension supports 9, 10 have been folded so that the folding carrier and the extension carrier connect to each other and the tool elements 1 1, 12, 13, 14 are horizontally outwards, while the tool elements 19, 20, 21, 22 run horizontally inwards towards each other and the free tool ends face each other immediately.
Fig. 3 zeigt eine Aufsicht auf den Werkzeugträger mit Rahmen in der Arbeitsposition, wobei die Laufräder als Tandem-Räderpaare 23 dargestellt sind. Vorzugsweise sind in Längsrichtung die beiden Einzelräder 23', 23" eines jeden Räderpaares 23 achsversetzt zueinander angeordnet, derart, daß das Rad 23' gegenüber dem Rad 23" vorläuft, wodurch sich ein ruhigerer Lauf des gesamten Werkzeugträgersystems ergibt. Die Werkzeugelemente, die in Fig. 3 generell mit W gekennzeichnet sind, sind in vier Reihen R1 - R4 angeordnet. Die Werkzeugelemente W der Reihe R1 sind an dem Querträger 24, die Elemente der Reihe R2 mit dem Querträger 25, die Elemente der Reihe R3 mit den Längszwischenträgern 26, und die Elemente der Reihe R4 mit dem Querträger 27 befestigt. Dabei ist der Abstand zwischen den Reihen R2 und R3 wesentlich größer gewählt als zwischen den Reihen R1 und R2, bzw. R3 und R4, um ausreichend Platz zur Unterbringung der Laufräder 23 und der Tiefenführung zu erzielen.Fig. 3 shows a plan view of the tool holder with frame in the working position, the wheels being shown as tandem wheel pairs 23. The two individual wheels 23 ', 23 "of each pair of wheels 23 are preferably arranged axially offset from one another in the longitudinal direction, such that the wheel 23' leads in relation to the wheel 23", which results in a smoother running of the entire tool carrier system. The tool elements, which are generally marked W in FIG. 3, are arranged in four rows R1-R4. The tool elements W of the row R1 are fastened to the cross member 24, the elements of the row R2 with the cross member 25, the elements of the row R3 with the longitudinal intermediate members 26, and the elements of the row R4 with the cross member 27. The distance between the rows R2 and R3 is chosen to be substantially larger than between the rows R1 and R2, or R3 and R4, in order to achieve sufficient space for accommodating the impellers 23 and the depth guide.
Die Figuren 4a und 4b zeigen den Vorgang des Aushebens des Werkzeugträgers, wobei in der Mittenlängsachse des Werkzeugträgers eine Schubstange 28 angeordnet ist und durch Betätigung von Antriebszylindern 29 in der Weise längsverschiebbar ist, daß die- se Längsbewegung in eine Verschiebung der Deichsel 30 und eine Schwenkbewegung des Oberlenkers 31 des Werkzeugträgers 1 umgewandelt wird.FIGS. 4a and 4b show the process of lifting out the tool carrier, a push rod 28 being arranged in the central longitudinal axis of the tool carrier and being longitudinally displaceable by actuating drive cylinders 29 in such a way that Se longitudinal movement is converted into a displacement of the drawbar 30 and a pivoting movement of the upper link 31 of the tool carrier 1.
Der Antriebszylinder 29 ist mit dem Trägerarm 32 des Tandem-Laufrades 23 gekoppelt, der starr an einem quer über den Werkzeugträger 1 verlaufenden Torsionsrohr 33 befestigt ist und bei einer Betätigung des Antriebszylinders 29 verschwenkt wird. Diese Schwenkbewegung wird auf das Torsionsrohr 33 übertragen, mit dem ein Flansch 34 starr befestigt ist, der die Schubstange 28 aufnimmt. Die Drehbewegung des Torsionsrohres 33 wird in eine Längsbewegung der Schubstange 28, und diese Längsbewegung wird über die Deichsel 30 in eine Schwenkbewegung des Oberlenkers 31 umgesetzt. 35 bezeichnet eine federbelastete Steinsicherung, 36 einen Werkzeugelementhalter. Der Winkel α gibt die Bewegung der durch die Betätigung des Antriebszylinders 29 erzielten Anhebung des Tandem-Rades 23 an, wobei aus darstellerischen Gründen das Rad 23 abgesenkt dargestellt ist, in Wirklichkeit jedoch der Werkzeugträger 1 angehoben wird. The drive cylinder 29 is coupled to the support arm 32 of the tandem impeller 23, which is rigidly attached to a torsion tube 33 running across the tool holder 1 and is pivoted when the drive cylinder 29 is actuated. This pivoting movement is transmitted to the torsion tube 33, with which a flange 34 is rigidly attached, which receives the push rod 28. The rotational movement of the torsion tube 33 is converted into a longitudinal movement of the push rod 28, and this longitudinal movement is converted into a pivoting movement of the upper link 31 via the drawbar 30. 35 denotes a spring-loaded stone safety device, 36 a tool element holder. The angle α indicates the movement of the lifting of the tandem wheel 23 achieved by the actuation of the drive cylinder 29, the wheel 23 being shown lowered for illustrative reasons, but in reality the tool carrier 1 is raised.
