  • apparatuses of the above-mentioned type can be used for collecting and selecting soil samples from soil other than farm land, such as mdus- trial and residential sites in order to examine the soil for pollution from e g pesticides
  • Apparatuses for collection of soil including a first element in the shape of a twist which is drilled into the ground and. accordingh . taken back up again When the twist has been taken up from the ground, large or less pan of the soil sample will fall from the threads of the twist and be collected
  • results are merely based on the selected soil sample which conse- quently only make up part of the collected soil sample. This results in unhomogeneous soil samples.
  • DE 36 12 406-al discloses an apparatus which does not employ a twist, but employs a pipe to take soil samples.
  • the apparatus is intended for taking soil samples concur- rently with the apparatus being lead forward above the surface of the ground.

  • the pipe is rotated on the wheel in a way that leads the pipe into the ground and up from the ground again concurrently with the apparatus being lead forward.
  • Said apparatus possesses considerable disadvantages.
  • the construc ⁇ tion necessary for the apparatus to function is very complicated, especially the con ⁇ struction for taking samples from the pipe. This results in a complicated and expensive apparatus for taking soil samples, which is a simple process in itself.
  • the apparatus is dependent on the fact that the soil does not contain stones or other alien substances. This causes malfunction of the apparatus and break-downs arise, if the soil contains such alien substances.
  • the pipe is fitted with a piston which is fitted with a slide that is lead through a groove in the pipe. This involves a risk that alien substances, such as stones, wedge in the groove resulting in the fact that the slide and thereby the piston cannot descend through the groove and the pipe, respectively.
  • DE 41 07 537 discloses a probe for taking soil samples and for direct in-situ meas ⁇ urement of various parametres of the soil in question.

  • the apparatus is furthermore fitted with tabs to secure the soil sample in the probe, after said sample has been lead up through the probe.
  • This is a disadvantage, as there is no certainty that the tabs can hold the soil sample, and also the tabs can be damaged, if the soil sample contains stones and other alien substances.
  • the use of a bevel probe results in difficulty descending the probe through the soil.

Abstract

La présente invention concerne un appareil de prélèvement et d'éjection d'échantillons de sol et l'utilisation de l'appareil considéré. L'appareil est constitué d'un premier élément tubulaire (1) et d'un second élément constituant un piston (2). Ce dernier est mobile par rapport au tube à l'intérieur duquel il se déplace. Le procédé de prélèvement d'échantillons (7) de sol consister à enfoncer le tube dans le sol (4), puis à sélectionner les échantillons de sol accumulés dans le tube en faisant descendre le piston dans le tube. Le prélèvement et la sélection peuvent se faire rapidement, voire de façon concomitante lorsque la sélection porte sur la totalité de l'échantillon de sol.
