Definitions

  • Soil cultivation device relates to a soil cultivation device according to the preamble of claim 1.
  • Soil cultivation devices such as cultivators or harrows, are used to loosen an upper layer of soil to break up clods of earth and produce good crumbs for seedbed preparation.
  • the soil cultivation devices include a support frame on which several soil cultivation tools arranged at least in a row next to one another are arranged.
  • the soil cultivation tools leave behind drawn longitudinal grooves or raised earth ridges.
  • a leveling means arranged on the support frame is arranged downstream of the floor cultivation tools in one working direction and serves to level the floor surface.
  • leveling means on soil cultivation devices known from the prior art in order to effect leveling.
  • a rotary harrow with a height-adjustable leveling bar for leveling is known.
  • a leveling means designed as a leveling rail is known. Tines are attached to the edge of the leveling rail facing the floor and are used to level the floor surface.
  • the DE 7421440 U1 describes a cultivator with soil cultivation tools arranged in a row next to one another, with each soil cultivation tool being followed by a leveling element in order to level the soil processed by the soil cultivation tools.
  • DE 7421440 U1 also mentions a chain pulled transversely to the direction of travel or work as a leveling means.
  • leveling elements Depending on the design of the leveling means as individual leveling elements or as leveling beams, different disadvantages arise. Individual leveling elements have the disadvantage that they do not enable optimal leveling across the entire surface. This results from the dependence of their position relative to the soil cultivation tools, to which the leveling elements are respectively arranged. Particularly in the case of cultivators which have three or more rows of tillage tools arranged one behind the other in the working direction, the offset of the tillage tools in one row to the following row transversely to the working direction results in a dependency of the arrangement of the respective leveling element with respect to the ridges resulting from the tillage Storage cannot be precisely defined.
  • Another disadvantageous aspect is the required installation space for the leveling elements in order to ensure trouble-free passage.
  • a leveling beam or a simple chain which contributes to leveling through its own weight, as a leveling means has the disadvantage that unwanted material can be thrown over, which disrupts the leveling appearance.
  • the invention is based on the object of developing a soil cultivation device of the type mentioned at the outset, which essentially avoids the disadvantages of the prior art, in particular that the leveling means is efficient and cost-effective and is characterized by a small space requirement. This task is achieved by a soil cultivation device with the features of independent claim 1.
  • a soil cultivation device comprising a support frame, on which a plurality of soil cultivation tools arranged next to one another in at least one row are arranged, which are followed in a working direction by a leveling means arranged on the support frame.
  • the leveling means comprises a flat leveling element which extends over a partial working width (AB') or the entire working width of the soil cultivation device and is flexible in itself, which extends essentially perpendicular to the ground to be leveled and rests with its free end on the ground .
  • the leveling element is characterized by a low installation depth, so that the overall length of the tillage implement is reduced, which has an advantageous effect on the center of gravity of the implement.
  • the leveling element can achieve optimal leveling over the entire working width of the tillage implement. In particular, there is no dependence on the storage position of the ridges created by the soil cultivation tools.
  • the term working direction refers to the direction of movement of the tillage implement in which the tillage implement is pulled over the soil to be worked.
  • the wording “flat leveling element” is to be understood broadly. This can be a continuously closed surface, with the leveling element being formed in one piece.
  • a segmented design of the leveling element is also conceivable, ie several individual elements extending over the (partial) working width of the soil cultivation device are arranged one above the other in the vertical direction, whereby these can be connected to one another like a hinge, comparable to the structure of a roller shutter.
  • the leveling element is in particular downstream of the last row of soil cultivation tools, which cause ridges to be raised.
  • the flexibility of the leveling element can be adjustable by means of one or more, preferably rod-shaped, support elements which extend over the width of the leveling element and which are arranged downstream of the leveling element when viewed in the working direction.
  • the support element exerts a supporting force on the leveling element, which is directed perpendicular to the essentially vertical surface of the leveling element.
  • a pivot axis can be set, about which a section of the leveling element located below the support element can pivot.
  • the support element exerts a compressive force on the leveling element as a counterforce to the material pushed on by it.
  • a selected vertical distance of the support element from the ground changes the flexibility of the leveling element in the area between the lower edge of the leveling element and the support element.
  • a reduction in the vertical distance is accompanied by an increase in the rigidity of the leveling element.
  • An increase in the vertical distance of the support element to the ground leads to a reduction in the rigidity of the leveling element.
  • the support element can be designed to be height-adjustable using height adjustment means that can be operated manually or with external energy or automatically. This makes it possible to adjust the vertical position of the introduction of pressure force through the support element, which is accompanied by a change in the opening position of the leveling element.
  • the force to be exerted by the pushed-on material on the leveling element can be adjusted, which leads to opening by swinging out about the pivot axis formed by the support element in order to avoid a build-up of material.
  • the position of the pivot axis can be changed for this purpose.
  • a pressure point shift occurs.
  • the manually operable height adjustment means of the support element can be set up for a stepless height adjustment or a height adjustment in discrete steps.
