Definitions

  • the invention is based on the technique described as water jet cut ⁇ ting. To a certain extent this technique is used in the industry for cutting plastic sheets, metal, and other materials.
  • the advantage by this rather than the mechanical control of undesi ed vegetation is that the method according to the invention is more careful with utili ⁇ ty plants which are undesired to control.
  • the cutting is concentrated on a small area which does not affect the surrounding area and accord ⁇ ingly, there is no risk that the processing in one area gives an unde ⁇ sired processing in another area, which could involve risk of damaging the utility plants.
  • the method also comprises means for detecting utility plants or for detecting weeds.
  • This detecting may be carried out in several widely different, known ways, e.g. by continuous measuring of the height of the plant either by means of light or sound reflectors, by photo recognition, by some kind of continuous biological or visual plant analysis, or in another way.
  • Fig. 1 shows a schematic view of an apparatus for use in the method
  • Fig. 2 shows a schematic view of a section through an embodiment for an apparatus for use in connection with the method according to the invention
  • Fig. 3 shows a possible embodiment for a mean for determining the distance between the surface of the ground and the detecting mean/nozzle
  • Fig. 4 shows a further embodiment which substantially corresponds to the embodiment shown in Fig. 3, but seen from the rear.
  • a valve 5 and/or a sheet 6 may be used for interrupting, respectively blocking the water jet 4.
  • the nozzle 3 is not as sensitive to impurities as the detecting mean 7, it is sufficient to shield these means 7 and refrain from shielding the nozzle 3. This may be desirable owing to the availabi- lity of servicing or the like around the nozzle.
  • the detecting mean 7 is located naturally in front of the nozzle 3 seen in the direction of travelling, shown with the arrow. If the travelling speed and the distance between the detecting mean and the jet, respectively, is known, it may be determined how long a time after the detecting of the utility plant/weed the water jet should be interrupted/established. Alternatively, it will be possible to locate the detecting mean 7 in a separate part of the apparatus which is not built integral with the nozzle 3. Hereby, the risk of functional errors in the detecting mean is reduced. Such functional errors may frequently be caused by smudging of sensors, optics, and the like, of which the detecting mean 7 is built up.
  • Fig. 3 shows a principle for how the distance between the surface J of the ground and the detecting mean 7, respectively the nozzle 3, may be determined and kept more or less constant while operating.
  • a wheel 11 is fixed to a shield 8, in which the detecting mean 7 and the nozzle 3 are located.
  • the whole system 12 consisting of the wheel 11, the shield 8, the detecting mean 7, and the nozzle 3 are suspended to a hauling machine 13.
  • nozzle 3 and the detecting mean 7 should be located in the immediate vicinity of the wheel 11, and that the wheel 11 is situated in the immediate vicinity of the row and thereby the plant P.
  • a reliable cutting is obtained even though the surface J of the ground is irregular.

Abstract

Procédé et appareil destinés au désherbage des cultures à l'aide d'un jet d'eau à haute pression servant à sectionner les tiges des mauvaises herbes au niveau du sol. On a prévu un dispositif de détection servant à distinguer les cultures des mauvaises herbes et à interrompre ou émettre le jet d'eau lors du passage devant les cultures et les mauvaises herbes, respectivement.
