Abstract

Cette invention concerne une récolteuse-hacheuse équipée d'un cylindre de coupe et d'un dispositif d'affûtage comprenant un chariot déplaçable transversalement sur une barre de support et recevant une pierre à affûter. Ce chariot est monté sur la barre de support au moyen de paliers à billes, plus spécialement de chemins de billes, ces dernières se déplaçant dans des fentes longitudinales ménagées dans le chariot. La pierre à affûter peut être collée sur une plaque vissée sur le chariot, ladite plaque présentant un évidement dans lequel la pierre à affûter est encastrée. Cet agencement réduit l'effort nécessaire au déplacement du chariot et supprime les dangers de rupture pouvant résulter d'une fixation de la pierre à affûter par serrage.This invention relates to a forage harvester equipped with a cutting cylinder and a sharpening device comprising a carriage movable transversely on a support bar and receiving a sharpening stone. This carriage is mounted on the support bar by means of ball bearings, more especially ball tracks, the latter moving in longitudinal slots formed in the carriage. The sharpening stone can be glued to a plate screwed onto the carriage, said plate having a recess in which the sharpening stone is embedded. This arrangement reduces the effort required to move the carriage and eliminates the danger of breakage which may result from fixing the sharpening stone by clamping.
