Abstract

L'invention concerne un dispositif d'ensemencement comprenant un rouleau constitué de plusieurs roues à tambour disposées les unes à côté des autres et pouvant être déplacées les unes par rapport aux autres dans le sens de la hauteur, indépendamment les unes des autres, ainsi que des socs associés aux roues à tambour. Lesdites roues à tambour sont articulées à l'aide de fixations sur un longeron, transversal au sens de la marche. Les socs sont montés derrière des roues à tambour à l'aide de bras de retenue sur les fixations des roues à tambour. Le montant supérieur de la fixation de type parallélogramme et les bras de retenue associés des socs sont réunis en une unité qui est solidarisée à la fixation restante des roues à tambour, à l'aide d'un assemblage amovible. L'invention concerne en outre une combinaison d'engins de culture agricole comprenant un cadre porteur portant au moins un réservoir et muni d'un châssis comportant des roues mobiles, ainsi qu'une barre de traction, au moins un cadre pour socs monté par l'intermédiaire d'un dispositif d'accouplement élevable et abaissable, sur le cadre porteur derrière les roues mobiles. Des socs sont montés sur ledit cadre pour socs, avec des éléments à tambour situés en avant, de manière à se déplacer dans un plan vertical. Les roues mobiles peuvent être soulevées du sol pendant les opérations de culture, par l'intermédiaire du dispositif d'accouplement ou d'un dispositif de levage séparé. Il est prévu des systèmes à effet ressort entre les éléments à tambour et le cadre pour socs.
