Definitions

  • SE 526 848 C2 shows a device for the releasable fastening of a spring-tine or the like for an agricultural machine having a transverse beam.
  • the spring-tine has a fastening portion with a through hole, so that the spring-tine can be fastened to the transverse beam by guiding a bolt through the hole in the spring-tine and through a hole passing through the beam, so that the bolt can engage with a nut situated on the opposite side of the beam. It may also be desirable to give the fastening portion of the tool a certain profile, for example to increase the rigidity, but with such profiles it is harder with the state of the art to achieve satisfactory fastening.
  • Fig. 5 shows a roller cylinder 10, constructed with a fastening like that in Figs. Ia and Ib.
  • Fig. 7 shows the roller cylinder in Fig. 6, viewed from above.
  • the fastening portion can be provided with a threaded hole 9, which can be a blind hole (not shown) or a through hole.
  • the support 5 has a first opening 7, which is configured to receive the fastening portion 2, and a second opening 8, through which a bolt can be inserted. Once the fastening portion 2 is sufficiently inserted through the first opening 7, the bolt can be brought into engagement with the threaded hole 9.
  • the first opening 7 can be configured such that the fastening portion, once it is inserted in the first opening, in the unloaded state, is not quite parallel with the inner surface 50 against which the fastening portion 2 is to be pressed, and such that a space S is thereby present between the fastening portion 2 and the inner surface 50.
  • This can be realized by at least one of the edge sides 54, 55 of the first opening being directed somewhat away from the inner surface 50.
  • both the edge surfaces can be angled relative to the inner surface 50.
  • the fastening portion can have a somewhat concave or cambered surface portion 51.
  • a concave surface portion of this kind tightening of the bolt 6 will produce a bending of the fastening portion 2 in the plane P2-P2 (Fig. 2), producing a pretensioning force which helps to give the tool a play-free fastening.
  • a concave surface portion can be realized by forging.
  • the head of the bolt can be made at least partly pliable. It is also possible to arrange a spring washer or the like between the head of the bolt and the support 5.
  • Fig. 8 shows an agricultural machine in the form of a harrow, which has both harrow tines 1, 1' and tines supporting levelling tools, so-called CROSSBOARD® tines 11, which are fastened in place in supports 5, 5' in the form of crossbeams made of quadrilateral tubes.
  • the harrow tine is fitted into a crossbeam, for example, by the fastening portion 2 of the harrow tine being inserted through the first opening 7 in the crossbeam 2, and a bolt 6 being inserted through the second opening 8 in the crossbeam 2, so that the bolt 6 is brought into engagement inside the crossbeam with the threaded hole 9 in the fastening portion 2.
  • a space S as a result of the configuration of the first opening 7, can be present between the inner surface 50 and the fastening portion (Figs. Ia, 2).

Abstract

La présente invention concerne un outil (1) pouvant être fixé de manière amovible dans un support (5), par exemple un longeron ou un axe, d'une machine agricole. Ledit outil comporte une partie servant à la fixation (2), conçue pour s'appuyer directement ou indirectement sur le support (5) et être maintenue dans une position fixe par rapport à lui, et une partie servant au travail (3). La partie servant à la fixation (2) est conçue, de par sa taille et sa forme, pour être introduite dans une ouverture correspondante (7) dans le support (5) et comporte un moyen d'engagement (9), conçu pour s'engager dans le support avec un élément de fixation (6), si bien que la partie servant à la fixation (2) est comprimée contre une surface intérieure (50) du support. L'invention concerne également une machine agricole comprenant un tel outil et un procédé de mise en place dudit outil sur une machine agricole.
