Definitions

  • the object of the invention is to design an extractor for plant roots, e.g. dandelions.
  • Several designs have seen the light of day and have been patented. They are characterized by the following features:
  • a foot rest or an ejector or both are used in e.g. British patent No. 449 583 e.g. German patent No. 201 391 e.g. US patent No. 1 576 798 e.g. US patent No. 1 548 040
  • the lower part of the extractor consists of two short elements (1), hereinafter called the "nip". These are so designed as to form two teeth (Id) which draw the extractor down into the earth when it is rotated counter-clockwise and cuts out a column of earth containing the root.
  • Step 1 The inner notch on the clamping handle (2) is placed in locking position in the slot (3) in order to hold the handles (4) and (5) a specific distance apart.
  • Step 2 The nip is now in its initial position (la).
  • Step 3 Pressing downwardly and at the same time rotating the extractor or turning it in quarter-turns one way and then the other in relation to the starting position of the handle which will cause the extractor to drill down into the earth. This shall be continued until just below the root.
  • Step 4 The clamp (2) is now released and the shaft (4) pulled apart until the clamp is restrained by its outer notch. The nip has now been pressed together to its position (lb).
  • Step 5 The extractor is pulled up. Since the distance between the shafts (5) is greater than the inner diameter of the nip, the column of earth will not adhere to these and can be removed by bringing the shafts (4) together. The distance between the rods (5) is thus increased and the column of earth fails out.

Abstract

L'effet voulu est obtenu par le fait que les deux moitiés de l'élément en forme de pince (1) sont inclinées (en 1d). Le cylindre à enfoncer dans la terre ne se fixe pas dans l'extracteur car le diamètre intérieur de la pince (1d) est inférieur à la distance comprise entre les tiges (5).
