Definitions

  • the invention relates to an arrangement of the conveyor trough in partial cutting machines, in which the conveyor trough is passed under the swivel mechanism of the cutting arm, the front end of the conveyor trough is articulated in the region of the loading table and the rear end thereof is adjustable in height, the conveyor trough has hinged parts.
  • the cut material is conveyed backwards from the loading ramp and dropped onto a connected conveyor at the rear end.
  • the height of the front end of the conveyor trough changes and depending on the height of the connected conveyor, the rear end must be adjusted.
  • the invention now aims to avoid jamming in the area below the swivel mechanism with certainty and therefore essentially consists in the conveyor trough having a stationary region extending underneath the swivel mechanism, at which the front part of the conveyor trough and the rear part of the same horizontal pivot axes are pivoted.
  • the conveyor trough is arranged in the area below the swivel mechanism, the height of the passage cross section below the swivel mechanism is not changed when the front end and / or the discharge end of the conveyor trough is adjusted and, above all, there is no jamming of chunks in the passage cross section come below the swivel mechanism.
  • the articulation axes are expediently in a plan view, as seen at the two ends of the area covered by the swivel mechanism or outside this area.
  • the conveyor trough 1 is passed under the swivel mechanism 2.
  • the lower limit of the swivel mechanism is indicated by 3 hatched.
  • the conveyor trough is thus covered by the lower limit 3 of the swivel mechanism 2.
  • the conveyor trough 1 has a stationary part.
  • On the stationary part 4 of the conveyor trough a front part 6 of the conveyor trough is pivoted about a horizontal pivot axis 5 and the front end of this front part 6 is pivoted about an axis 7 on the loading ramp 8.
  • At the rear end of area a is at the stationary part 4 of the conveyor trough 1 pivoted about a horizontal pivot axis 9, the rear part 10 of the conveyor trough 1.
  • the loading ramp 8 can now be raised to the position 8 'shown in dashed lines and lowered into the position 8 "shown in dashed lines.
  • the front articulation point 7 of the pivotable conveyor trough part 6 is thus also raised or lowered.
  • the rear part 10 of the conveyor trough can also be moved into the Position 10 'are raised.
  • the passage cross-section below the swivel mechanism 2 i.e. the passage cross section, changes due to the lifting of the loading ramp 8 and the lifting of the dropping end of the rear part 10 of the conveyor trough. in area a, not so that the risk of larger pieces getting stuck in area a is avoided.
  • the vertical swivel axis of the swivel mechanism is indicated at 11.
  • the cutting arm 12 can be pivoted about a horizontal axis indicated by 13.
  • 14 represents the cutting head.
