Abstract
Cette invention concerne une récolteuse-hacheuse comprenant un cylindre de coupe et un dispositif d'affûtage réglable en hauteur, comprenant un chariot sur lequel la pierre à affûter est montée et porté lui-même par une barre de support déplaçable verticalement. Cette barre s'étend jusqu'aux deux côtés du carter de la récolteuse-hacheuse et ses extrémités sont montées avec le dispositif de réglage en hauteur dans un boîtier qui est rendu étanche par rapport au carter de la récolteuse-hacheuse, par exemple au moyen d'un joint flexible entourant les extrémités de la barre de support. Cet agencement permet de soustraire le dispositif de réglage de hauteur prévu pour le dispositif d'affûtage aux influences extérieures, en particulier à l'effet nuisible de la poussière et de la saleté.This invention relates to a forage harvester comprising a cutting cylinder and a height-adjustable sharpening device, comprising a carriage on which the sharpening stone is mounted and itself carried by a vertically movable support bar. This bar extends to both sides of the forage harvester housing and its ends are mounted with the height adjuster in a housing which is sealed with respect to the forage harvester housing, for example by means of a flexible gasket surrounding the ends of the support bar. This arrangement makes it possible to shield the height adjustment device provided for the sharpening device from external influences, in particular the harmful effect of dust and dirt.
