Title
(EN) AGRICULTURAL IMPLEMENT AND METHOD OF CONTROLLING AGRICULTURAL IMPLEMENT
(FR) OUTIL AGRICOLE ET PROCÉDÉ DE COMMANDE D'OUTIL AGRICOLE
Abstract
(EN)
The document discloses an agricultural implement, comprising a main frame (11), which carries a plurality of soil working tools (32), a first support frame (12a), which is pivotally connected to the main frame (11) via a first support frame joint (21a) and which carries at least one first rolling ground support (31a), such as a wheel or a roller, a control lever (13) rotatably connected to the main frame (11) via a control lever joint (22), a support frame control link (14) rotatably connected to the control lever via a first support frame control link joint (23a) and which is pivotally connected to the support frame (12) via a second support frame control link joint (23b) so that rotation (V1) of the control lever (13) around the control lever (22) provides rotation (V2) of the first support frame (12a) relative to the main frame (11), wherein the control lever (13) is rotatable in a first direction of rotation (V1) so that the first support frame control link joint (23a) can pass a line (C1 ) through rotation centers of the control lever joint (22) and the second support frame control link joint (23b) and wherein the first support frame (12a), when the first support frame control link joint (23a) passes the line (C1), changes direction of rotation (-V2).
(FR)
La présente invention concerne un outil agricole, comprenant un châssis principal (11), qui porte une pluralité d'outils de travail du sol (32), un premier châssis de support (12a), qui est relié de manière pivotante au châssis principal (11) par l'intermédiaire d'une première articulation de châssis de support (21a) et qui porte au moins un premier support au sol roulant (31a), tel qu'une roue ou un rouleau, un levier de commande (13) relié rotatif au châssis principal (11) par l'intermédiaire d'une articulation de levier de commande (22), une liaison de commande de châssis de support (14) reliée rotative au levier de commande par l'intermédiaire d'une première articulation de liaison de commande de châssis de support (23a) et qui est reliée pivotante au châssis de support (12) par l'intermédiaire d'une seconde articulation de liaison de commande de châssis de support (23b) de telle sorte que la rotation (V1) du levier de commande (13) autour du levier de commande (22) fournit une rotation (V2) du premier châssis de support (12a) par rapport au châssis principal, le levier de commande (13) pouvant tourner dans un premier sens de rotation (V1) de telle sorte que la première articulation de liaison de commande de châssis de support (23a) peut passer une ligne (C1) à travers les centres de rotation de l'articulation de levier de commande (22) et de la seconde articulation de liaison de commande de châssis de support (23b), et le premier châssis de support (12a), lorsque la première articulation de liaison de commande de châssis de support (23a) fait passer la ligne (C1), changeant le sens de rotation (-V2).
