Definitions

  • the present invention relates to a soil cultivation device with soil cultivation tools, in particular disc tools, which are arranged in several rows of tools that follow one another in the working direction and are oriented transversely to the working direction, and a chassis with at least one main wheel.
  • the present invention relates generally to a soil cultivating implement which can be pulled over the ground with a drawbar behind a tractor in order to work the ground.
  • the soil cultivation device can be a disc harrow, the invention described below also being applied to similar soil cultivation devices, i.e. Soil cultivation devices with a similar structure and / or similar arrangement of soil cultivation tools, for example six-disc, hollow discs, cross-cutters, rollers, clearing shares or clearing stars, leveling tools or cross-boards, can be used.
  • the soil cultivation device is carried by a height-adjustable chassis that can also be used to transport the soil cultivation device in a transport position over public paths and roads between different locations.
  • Mechanisms generally known for such tillage tools for example traction amplifiers, in which the force or weight distribution between tractor and tillage device can be set or changed, folding mechanisms, by means of which a width of the tillage device is reduced to a value permissible for public roads or to a value for tillage efficient value can be increased as well as additional tools like grading tools, rollers, in particular
  • Depth control rollers, harrows and the like can be particularly advantageous in connection with the present invention.
  • the invention is therefore suitable especially for those tillage implements that have appropriate mechanisms.
  • an object of the present invention is to provide a soil cultivation device with soil cultivation tools, in which the soil cultivation tools are arranged in such a way that a high degree of maneuverability, clean follow-up journeys and uniform soil cultivation are achieved.
  • Another object of the invention is to achieve an optimal utilization of the installation space of the frame surface in order to be able to manufacture the device as compactly and efficiently as possible.
  • one main wheel or the several main wheels as well as between the main wheels can be arranged in front of the foremost complete row and, if they are arranged according to the invention, be arranged without impairing maneuverability, evenness or freedom from side drafts.
  • a main wheel or several main wheels is to be understood as meaning, in particular, the wheel or wheels which, in contrast to one or more support wheels, continuously absorbs a greater weight during use of the soil cultivation device or at least during transport or turning processes.
  • the above-mentioned wheel spacing is to be understood as the distance between an outer edge of the main wheel and the central longitudinal axis.
  • the width of the main wheel in question is therefore included in the wheel spacing.
  • the arrangement according to the invention not only ensures that maneuverability of the device, freedom from side pulls when using the device and uniformity of processing are achieved. It also enables a high level of stability, since the foremost tillage tools, seen in the working direction, are in the front area of a triangle between the outermost contact points of the chassis and the support point of the Soil cultivation device located on a tractor or the like, for example the end of a drawbar of the soil cultivation device.
  • the chassis can guide the tillage in a stable manner.
  • the chassis preferably has two flaup wheels, each of which is spaced apart from the central longitudinal axis by the same lateral wheel spacing.
  • the stability of the soil cultivation device around the longitudinal axis can be increased by using two flaup wheels without requiring a particularly wide main wheel.
  • Another soil cultivation tool according to the invention has a central longitudinal axis, soil cultivation tools, in particular
  • Disk tools which are arranged in several rows of tools that follow one another in the working direction and are aligned transversely to the working direction, and a chassis with at least two main wheels spaced apart transversely to the working direction.
  • the chassis is arranged with respect to the tillage tools in such a way that at least one tillage tool is arranged with respect to the working direction in front of and to the left and right of the chassis, so that the chassis interrupts at least one of the rows of tools over a chassis width extending transversely to the working direction, one in the working direction at Farthest row of tools arranged in front of the chassis extends transversely to the working direction over no more than the chassis width.
  • the chassis width is defined by the area across which the row of tools interrupted by the chassis is tool-free, i.e. across the working direction. how many soil cultivation tools are missing compared to a consistent continuation of the tool line in the area of the chassis and where these missing soil cultivation tools would be arranged with a consistent continuation of the tool line.
  • a tillage tool field has been removed from the row of tools laterally surrounding the chassis and in front of the other foremost one Tool line placed.
  • the chassis can be moved forward in the working direction compared to a position as in EP 3 122 168 A1, which shortens the wheelbase, i.e. the distance between the chassis and a drawbar or the flinter axle of a tractor, and improves the maneuverability of the combination without doing so
  • the tillage tools which give way to the chassis are arranged in front of the otherwise foremost row of tools and are therefore not left out.
  • leveling tools can be used behind the soil working tools in a manner known in principle.
  • rollers, guide plates and / or harrows are suitable for this.

  • Soil tillage tools of a row of tools is offset in the working direction by up to half a distance between successive rows of tools, is still considered to belong to this row of tools.
  • the same number of soil cultivation tools are arranged on both sides outside the central longitudinal axis. This means that, for example, in the case of an uneven number of tillage tools per row, tillage tools also centrally, i.e. can be arranged on the central longitudinal axis. In this way, it can be achieved that the soil cultivation device does not pull sideways.
  • At least one front support wheel is preferably arranged to the left and right of the row of tools furthest in front of the chassis and in the same position as this tool row along the working direction, so that the tillage tools of this tool row are flanked by the front support wheels.
  • the stability of the soil cultivation device is increased by the support wheels and the depth control of the soil cultivation tools can take place with the aid of the support wheels in addition to the chassis, ie the main wheels, and / or a depth control roller. If one or more support wheels or one or more depth control roller (s) are arranged behind the main wheel, it is possible to compensate for a negative support load during work.
  • the support wheel or wheels or the depth control roller (s) is or are arranged approximately 30 cm behind the main wheel or wheels. This distance enables this effect to be achieved without having to exert particularly large forces from the support wheel or the support wheels or depth control roller (s) if the lever arm between the support wheel / depth control roller and the main wheel is small, and without having to give up the advantage of a compact design, when the lever arm between the support wheel / depth control roller and the main wheel becomes large.

  • the tillage tools of the row of tools furthest in front of the chassis which are located furthest to the side from the central longitudinal axis, are arranged in line with the main wheels of the chassis in the working direction.
  • This configuration means that soil thrown up by the tillage tools reaches the main wheels of the chassis and is compacted by them, which overall results in a more even tillage because the main wheels otherwise compact the soil, which is formed without additional soil and thus without alternative or additional countermeasures can lead to ruts.
  • the soil cultivation tools are arranged obliquely and preferably hollow disks, each defining a throwing direction, the throwing direction of the tillage tools of the rearmost row of tools pointing towards the central longitudinal axis, the throwing direction of the tillage tools of the tool rows arranged one behind the other alternately away from the central longitudinal axis and towards the central longitudinal axis demonstrate.

  • the depth control roller is or the depth control rollers are preferably arranged in the working direction behind the chassis in order to assume a favorable lever position for applying the force required for depth control to the ground. Since the depth control roller is not required to support the soil cultivation device, it has no negative effects behind the chassis on the maneuverability of the soil cultivation device or combination comprising the soil cultivation device and a tractor.
  • a roller arranged behind the chassis with a width of up to the chassis width further forward than rollers or roller parts outside the range of the chassis width, i.e. with a greater lateral distance from the central longitudinal axis.
  • One or more rollers and / or one or more harrows can also be arranged as leveling tools behind the soil cultivation tools.
  • At least one of the additional tools which is on the central longitudinal axis or directly adjacent to it, is opposite the other additional tools of its additional tool row in the working direction forwards or backwards, preferably by 1/3 to 1/2 times its length along the working direction, offset.
  • the amount of offset is preferably 30% or more, more preferably 50% or more at the same time more of a diameter of the additional tool if it is disc-shaped.
