Title
(EN) WEED SEED DESTRUCTION
(FR) DESTRUCTION DE GRAINES DE MAUVAISES HERBES
Abstract
(EN)
Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds into contact with stator bars at angularly spaced positions around the axis of the rotor. The stator bars are formed from bent sheet metal which are L-shaped or U-shaped in cross-section to define a first leg lying in a cylindrical surface surrounding the axis of the rotor and a second leg extending outwardly from the cylindrical surface connected to the first leg at an apex at a leading end of the first leg relative to the direction of rotation of the rotor. When U-shaped, the bars are symmetrical and can be reversed when the second leg is worn for extended life.
(FR)
Les graines de mauvaises herbes sont détruites dans la balle par une moissonneuse-batteuse sous l'effet d’impacts à grande vitesse répétés provoqués par un rotor monté dans l'une des paires de carters côte à côte qui accélère les graines rejetées et les amène en contact avec des barres statoriques dans des positions angulairement espacées autour de l’axe du rotor. Les barres statoriques sont formées à partir de tôle pliée en forme de L ou de U en coupe transversale pour définir une première jambe se trouvant dans une surface cylindrique entourant l'axe du rotor et une seconde jambe s'étendant vers l'extérieur à partir de la surface cylindrique reliée à la première jambe au sommet au niveau d'une extrémité avant de la première jambe par rapport au sens de rotation du rotor. Lorsqu'elles sont en forme de U, les barres sont symétriques et peuvent être inversées lorsque la seconde jambe est usée pour une durée de vie prolongée.
