  • the invention further relates to a harvesting attachment for a harvesting machine and a harvesting machine, in particular a combine harvester.
  • the picking unit for corn or the like comprises a housing and a picking gap, on which two counter-rotating feed rollers are arranged.
  • Such a picking unit is known from DE 299 09 358 U1.
  • the object of the invention is to improve the chopping effect in a picking unit of the type specified.
  • the picking gap runs in a horizontal direction or in an approximately horizontal direction with an inclination from the front bottom to the rear top. It runs in the direction of the direction of movement of the harvester, which may in particular be a combine harvester.
  • the picking unit is arranged in the direction of movement in front of the harvester.
  • the feed rollers are on both sides of the picking gap. They are lost in the sentlichen parallel to the picking gap and at a distance from each other. The feed rollers are below the picking gap.
  • the picking unit may comprise further components. It may in particular comprise rotating cutting blades.
  • the cutting blades rotate about a vertical or substantially vertical axis, ie in a horizontal or substantially horizontal plane.
  • the thus rotating cutting blades form a horizontal chopper. They are located below the feed rollers.

  • the picking unit has a horizontal chopper which is arranged in front of the vertical chopper. Then you can too the remaining stalks, which are not detected by the horizontal chopper, are chopped by the vertical chopper. In this way it can be achieved that the organic material rotted better. In particular, it can be prevented that insects, which are problematic for the cultivation of the corn plant or other plant, can propagate inside the stem and / or overwinter.
