Abstract

La présente invention concerne un système d'engrenages pour système de dosage et de guidage de graines, comprenant un système d'engrenages (40, 50, 60, 70), de diverses tailles, pouvant loger et transporter les graines depuis le système de sélection jusqu'au sillon de plantation au moyen de mouvements synchrones dans des sens opposés qui guident les graines de manière uniforme. Ainsi, ce nouveau type de structure d'actionnement et de système d'engrenages permet d'augmenter la vitesse de déplacement des graines de manière à compenser le déplacement du tracteur, sans subir l'action du tremblement de la ligne, un espacement correct étant en outre maintenu par rapport au sillon de plantation.
