Definitions

  • the 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
  • the plow boom 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.
  • the prerequisite for good and clean plow work is an exact match of the plow to the respective tractor.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the plow tree can be carried out in any manner, since a tubular profile is not required.
  • 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.
  • 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.
  • 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 -
  • shock absorber thus protects the plow components connected downstream of the shock absorber and also the tractor against jerky loads
  • a particularly advantageous embodiment of the invention provides that a hydraulic shock absorber device is integrated in the hydraulic system of the hydraulic cylinder.
  • the new swivel plow can also be provided with a display device which indicates the respective axial displacement position of the plow tree.
  • FIG. 1 is a top view of a swivel plow according to the invention
  • FIG. 2 shows the side view of the plow tree with the plow bodies of the swivel plow according to FIG. 1.
  • 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.
  • 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.
  • 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.
  • 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.
  • the plow boom 4 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

Abstract

Charrue réversible comportant une flêche droite (4) qui supporte les éléments de charrue (5) réparties sur sa longueur axiale et qui peut être basculée d'une de ses positions de travail dans une autre sur un axe de pivotement (12) du châssis (3). Il est proposé, afin d'améliorer le réglage de la largeur du sillon avant, que la flêche (4) soit montée dans le châssis articulé, de façon qu'elle puisse, avec les éléments de charrue (5) qui sont fixés sur elle, se déplacer dans le sens de sa longueur axiale, par rapport à l'axe de pivotement (12).
