Definitions

  • the present invention relates to a soil treating implement, in particular for use as an after-runner in connection with harrows or corresponding devices.
  • the invention aims at a soil treatment of grass and stule fields, whereby it is possible to completely renounce the traditional ploughing and only make use of a single or a few treatments with cultivator or harrow implements with an afterrunner according to the present invention.
  • FIG. 1 is a schematic perspective view of an arrangement according to the invention
  • Fig. 2 is a plan view of one of the coarsely indented cutter discs used therein;
  • Fig. 3 is a sectional view thereof; and Fig. 4 is a perspective view thereof.
  • a first soil treating device A is indicated, e.g. in the form of a stule harrow or a combination of two different devices propelled by a tractor in direction of the arrow shown towards the right.
  • a unit B according to the invention, comprising a row of passively rotary cutter discs 2 provided with marked, triangular incisions 4 in their periphery, between which there are left projecting wing blade portions 6.
  • each of these wings is bent out to one side along a bending line "a", which extends obliquely to the effect that a wing blade front edge 8, which is leading in the direction of rotation, is bent out only at a short outer end area 10, while the rear edge area 12 is bent out along the entire or almost the entire length thereof.
  • the degree of bending may be more or less, but for achieving a noticeable effect the bending angle should not be below some 10° and not above some 60°.
  • a preferred interval is 20-50°.
  • the depth of the V-shaped incisions between the cutter wings should be some 25-75% of the wing radius, preferably some 50% as shown in Fig. 2.
  • the number of cutter wings may be up to 10-12, but preferably lower, viz.
  • the cutter discs 2 may be arranged in groups, each e.g. with four discs mounted on a common shaft in such a manner that the wingshares 6 in the respective groups are phase displaced from each other, for formation of a treating unit which, despite the coarse indentation of the cutter discs, yet forms a collected, contiually operating rotation unit which, in projecting into the soil e.g. to a depth indicated by the dotted line shown in Fig. l, will be influenced to rotate constantly during the propelling of the implement.
  • the cutter discs When the implement is driven forwardly with a conventional working speed, the cutter discs will rotate vividly, whereby the cutting front edges 8 of the wing blades, during their downstroke in the ground and by their swinging up therefrom, will excert a cutting and separating effect, while by their upstroke the bent out wing portions 6 will cause an up- and ourthrowing of earth and plant portions.
  • the result When this occurs at each wing blade passage the result will be a heavy turbulence, by which it is achieved that the plant portions are effectively admixed into the earth in conjunction with the soil surface being effectively loosened. This implies a good moulding down of straw and plant portions and an efficient preparation of the seedbed.
  • the cutter discs are arranged such that they throw out the earth to both sides of the middle of the implement .
  • the bending lines "a" may be located otherwise, and the bendings should not necessarily occur along a single bending line.
  • Such a transition is indicated on the lower wing to the right in Fig. 2, where a fan of bending lines a' is shown; by this fan formation the wing tip will not only be bent out, but also twisted somewhat, which has been found particularly advantageous.
  • the wing tip may be prolonged as indicated in dotted lines.
  • the number and the width of the wings may be varied as desired, and the wing periphery may be sharpened.

Abstract

La présente invention concerne un instrument aratoire destiné en particulier à parachever le travail de la herse ou similaire. Cet instrument, qui se présente sous la forme d'un tambour discoïde, ou sous la forme de disques à couteaux mus par la friction du sol, comporte des dents grossières conçues de façon à former des ailettes pourvues d'un bord d'attaque effilé et d'une partie postérieure en lame latéralement recourbée vers l'extérieur.
