Definitions

  • Such a combination of two defoliation units with different modes of action reduces the working time by around half compared to separate use and also allows the different modes of action of the individual defoliation units to be used in a synergistic manner.
  • the first defoliation unit in the working direction is designed as a roller defoliator with rollers that can be driven in opposite directions
  • the second defoliator unit in the working direction is configured as a compressed air defoliator with rotating compressed air jets directed at the plant areas to be defoliated, preferably with pulsed compressed air jets, the compressed air jets from nozzles emerging from a rotating drivable nozzle arrangement, rotate on a circular path, the diameter of which corresponds essentially to the effective working height of the rollers that can be driven in opposite directions and thus to the height of the associated working opening or recess for the roller debarker.
  • FIG. 1 shows the use of the device according to the invention on the cantilever arm of a tractor in the form of a basic illustration
  • the compressed air jets emerge from nozzles 14 of two rotating nozzle arrangements 15 (FIG. 5) and rotate on two circular paths, the diameter 16 of which is smaller than the fleas 17 of the working opening 8 formed in the shield for the roller deadener.
  • the common effective working height 18 of the plurality of rotating compressed air jets corresponds to the working height of the rollers that can be driven in opposite directions and thus the fleas 17 of the associated working opening 8 for the roller defector.
  • the working openings 9 are each designed as a partial circle, ring-shaped opening slots for the rotating compressed gas jets and the diameter of the respective opening slots corresponds to the diameter 16 of the circular path on which the respective associated outlet nozzles 14 rotate.
  • pressurized gas deaerators with rotating pressurized gas jets are also known per se, which is why the two double units 201 and 202 are not described in any further detail here.
  • a particularly important characteristic of the embodiment of the embodiment of the defoliation device according to the invention described here can be clearly seen both in FIG. 3 and in FIG.
  • the front surface of the shield 7, i.e. the surface facing the plant, is provided in the area of the working openings 9 for the second defoliation unit 200 in the working direction with a recess 19 opposite the front surface in the area of the working opening 8 for the first defoliation unit 100 in the working direction, so that the respective surface areas have an offset 20 with respect to the plant area to be defoliated.
  • guide elements for parts of plants are provided, in this embodiment as guide rods 21 extending in the working direction on the upper and lower edges of the shield.
  • the guide rods are bevelled in a recessed manner on the inlet side and outlet side.
  • roller defoliator 100 defoliation unit, roller defoliator

Abstract

L'invention concerne un dispositif de défoliation (3) comprenant au moins deux unités de défoliation (100, 200) qui sont situées sur le côté arrière d'un panneau commun (7) du dispositif (3), la surface côté avant dudit panneau faisant face à une plante à défolier, le panneau (7) étant doté d'ouvertures de travail (8, 9) ou de découpes à travers lesquelles les unités de défoliation (100, 200), qui sont situées sur le côté arrière, agissent sur les plantes, le dispositif de défoliation (3) pouvant être déplacé au-delà des plantes dans une direction de travail, et dans chaque cas, deux unités de défoliation (100, 200) ayant différentes manières de fonctionner étant placées l'une derrière l'autre dans la direction de travail de telle sorte que lesdites unités agissent séquentiellement sur la région de plante à défolier.
