Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • FIG. 1 is a schematic representation of the tool carrier according to the invention in the working position
  • FIG. 2 shows the arrangement according to FIG. 1 in the folded-up driving position
  • Fig. 3 is a plan view of the tool carrier

  • 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.

Abstract

L'invention concerne un porte-outils pour machines de labourage et de travail du sol, dont la largeur totale de travail est importante. Ce porte-outils comporte des supports prolongateurs (9, 10) fixés sur un support médian (1), de manière à pivoter de part et d'autre, et auxquels se raccordent des supports rabattables (17, 18) vers l'extérieur. Lorsque les machines circulent sur des routes, les supports rabattables (17, 18) pivotent de 90° en position verticale, de manière que les éléments d'outils des supports prolongateurs (9, 10) se trouvent en position horizontale vers l'extérieur, que les éléments d'outils des supports rabattables (17, 18) s'étendent horizontalement les uns sur les autres vers l'intérieur et que les éléments d'outils situés vers l'extérieur obturent les deux extrémités du support médian (1), de manière à en être à fleur. Pour soulever le support d'outils, les bras supports destinés aux roues porteuses, qui sont fixés de manière fixe sur une barre de torsion, sont actionnés par l'intermédiaire de vérins d'entraînement. La barre de torsion subit une torsion et cette torsion est convertie en mouvement longitudinal d'une barre d'accouplement qui imprime quant à elle un mouvement pivotant au timon et au bras oscillant supérieur.
