Definitions

  • the invention relates to a sowing device for an agricultural sowing and / or fertilizing machine according to the preamble of claim 1 and an agricultural sowing and / or fertilizing machine according to the preamble of claim 10.
  • sowing and / or fertilizing machines are used to deposit granular and / or liquid material, in particular seeds, fertilizer and / or dressing, on an agricultural area, in particular arable land.
  • the sowing and / or fertilizing machine usually comprises at least one storage container from which the granular and / or liquid material can be fed via, in particular pneumatic, conveying lines to several sowing devices, in particular coulters, arranged transversely to a direction of travel.
  • the granular and / or liquid material can be applied in the area of the sowing device on the arable soil, in particular next to and / or within at least one furrow formed by means of the coulter.
  • the sowing devices used within the sowing and / or fertilizing machines are typically arranged in the manner of a tine field, i.e. several sowing devices, viewed in the direction of travel of the sowing and / or fertilizing machine, one behind the other and / or next to one another.
  • This type of arrangement is used, on the one hand, to achieve particularly large working widths and, on the other hand, to achieve particularly high working speeds.
  • the sowing devices that can be used here comprise in each case at least two closing and / or depth control rollers arranged in the direction of travel behind the at least one coulter. These serve, among other things, to guide at least one coulter in depth, in particular several different placement depths, and / or to at least partially close and / or press down the furrow formed by means of the coulter.
  • the coulters that can be used within the sowing devices are usually designed as tine coulters, in particular chisel coulters, disc coulters, in particular double disc coulters, also being usable.
  • tine coulters in particular chisel coulters
  • disc coulters in particular double disc coulters
  • coulters can be designed as multi-link coulters articulated in the manner of a parallelogram or pivot coulters articulated via a support arm.
  • DE 102007011 752 A1 describes one of these via at least one
  • Sowing device that can be arranged on a sowing and / or fertilizing machine support arm.
  • the at least one share is coupled to the support arm and is set up to form at least one furrow that is suitable for depositing granular and / or liquid material in an arable soil.
  • At least one closing and / or depth control roller is arranged behind the coulter in the direction of travel and is mounted rotatably about an axis of rotation oriented transversely to the direction of travel.
  • the at least one closing and / or depth control roller has a contact area that can be brought into contact with the arable soil.
  • the disadvantage of this structure is, among other things, that the at least one closing and / or depth control roller is arranged in line with the coulter and / or the furrow and the furrow and / or the arable soil is above the deposited material, especially in the contact area, with an between the Closing and / or depth control roller and the arable soil acting pressure is compressed.
  • the pressure here is at least essentially influenced by a coulter pressure that can be set for the coulter.
  • a separate adjustment of the pressure exerted by the closing and / or depth control roller on the furrow and / or the soil is only possible to a limited extent or not at all with the sowing device described here.
  • the area of the deposited item in particular the area directly above the item, can condense

  • This has the disadvantage that a large number of components has to be kept available for the conversion of previous sowing devices and / or particularly long conversion times have to be accepted.
  • Another disadvantage is that there is a particularly high dependency between the coulter pressure required for the coulter and the pressure for pressing the soil and / or the furrow.
  • the object on which the invention is based is thus to design a sowing device in such a way that the compaction of the arable soil required to press the respective crop can be adjusted in a particularly flexible and simple manner.

  • Depth control rollers in particular their contact areas, can be moved relative to one another.
