  • the conveyor element 76 therefore fixes the two fastening sections 71 at the desired distance from one another. With the central region 76.1 and the two bends 76.2, the conveying element 76 simulates the trough-shaped geometry of the flap 72 or the conveying trough 36.
  • a material section 76.9 made of a pliable material for example a material web made of rubber or plastic, can rest at least in some areas.
  • This embodiment is, for example, in the Figures 9 and 10 shown.
  • the material section 76.9 can be clamped in the manner of a drum covering on the outer sides of the folds 76.3, so that the material section 76.9, especially in the central area 76.1 and in the area of the bends 76.2, can be set into particularly strong vibrations when the conveyor unit 70 is together with the sieve unit 30 swings in order to prevent clumping and jamming of the conveyed material arranged thereon.
  • the material section 76.9 is provided from the limp material instead of the sheet metal section 76.8 and rests directly on the support structure 76.4, 76.5 of the conveying element 76.
  • the material web 76.9 is clamped and held on the outside at the folds 76.3 and lies only in the middle area 76.1 and in the area of the bends 76.2 on the support structure 76.4, 76.5.
  • the support structure 76.4, 76.5 or additionally it is also conceivable that at least one stiffening element (not shown) is present in or on the material section 76.9.
  • the stiffening element or elements can be made of plastic or metal, for example.
  • the conveying element 76 can be brought into the desired shape and held in this shape.
  • the central region 76.1 and the bends 76.2 which adjoin it laterally can be formed by the support structure 76.4, 76.5 and / or the stiffening element or elements in the conveying element 76, so that they emulate the trough-like geometry of the flap 72 or the conveying trough 36.
  • connection between the clamping sections 80.1, 80.2 is released in order to release the clamping holder of the bearing sections 75.1.
  • a suitable tool is then brought into engagement with the actuating element 75.2.
  • the flap 72 can then be rotated until it is in the Figures 2 and 8th shown pivot position reached.
  • the released clamping sections 80.1, 80.2 serve as bearing mounts.
  • the conveying path between the conveying trough 36 and the conveying element 76 is interrupted.
  • the material stream coming from the conveyor trough 36 is now passed directly onto the discharge belt 50.
  • the flap 72 blocks the path between the conveying trough 36 and the conveying element 76 and, for this purpose, also protrudes a little above these components.
