Title
(EN) ROTARY AGRICULTURAL TOOL
(FR) OUTIL ROTATIF POUR L'AGRICULTURE
Abstract
(EN) There is disclosed a rotary agricultural tool which may be incorporated in a number of different types of agricultural equipment, such as in a device for chopping-up bulk material. The rotary tool comprises an elongate cutter body (170) mounted in a frame for rotation about a substantially horizontal axis and carrying on its outer periphery pivotally mounted cutter blades (169), a housing (115, 160) extending partly around the cutter body (170), and feed rollers (120) for feeding the bulk material to the cutter body (170). The baldes (169) are arranged in pairs of blades (171), and each blade is mounted in position on the cutter body in such a way that: the blade is pivotable relative to its mounting (172) between an outwardly extending operative chopping position and an inoperative position; the radially inner end (175) of the blade is engageable with a stop in order to define the operative position; the general axis (178) of the blade extends through the pivotal mounting (172) and in a direction which is rearwardly inclined to a radius (179) passing from the centre (180) of the elongate body (170) and through the pivotal mounting (172) with respect to the normal direction of rotation of the cutter body (170); and a retading device (172, 173, 174) is coupled with the blade and which tens to maintain the blade in any particular angular position about its pivotal mounting (172) unless the balde is acted upon by a turning moment about its pivotal mounting which is in excess of a predetermined minimum turning moment determined by the retarding device. This arrangement of the baldes provides for quiet operation, and storage of rotational energy in the blades which is effective to carry out efficient chopping operations on the bulk material.
(FR) Outil rotatif pour l'agriculture qui peut être intégré à un certain nombre d'équipements de differents types utilisés pour l'agriculture, comme par exemple dans un système pour couper un matériau en vrac. L'outil rotatif comprend un élément de coupe de forme allongée (170) montés dans un élément cadre afin de tourner d'un axe pratiquement horizontal et portant sur son portour extérieur des lames coupantes montées de manière pivotante (169), un logement (115, 160) se situant en partie autour de l'élément de coupe (170) et des cylindres d'alimentation (120) fournissant le matériau en vrac à l'élément de coupe (170). Les lames (169) sont disposées en paries (171), et chaque lame est positionnée sur l'élément de coupe afin que la lame pivote par rapport à son bâti (172) entre une position de coupe s'étendant à l'extérieur et une position de repos; l'extrémité radiale interne (175) de la lame vient s'engager dans un arrêt afin de définir la position d'exécution; l'axe général (178) de la lame s'étend et traverse le bâti pivotant (172), dans un sens qui est incliné vers l'arrière vers un rayon (179) passant du centre (180) de l'élément allongé (170) et au travers du bâti pivotant (172) par rapport au sens de rotation normal de l'élément de coupe (170); un dispositif de retardement (172, 173, 174) est couplé à la lame et tend à maintenir la lame dans n'importe quelle position angulaire particulière autour de son bâti pivotant (172), sauf si la lame est mise en marche par le moment d'un couple autour de son bâti pivotant, moment alors excédentaire par rapport à un moment de couple minimum prédéterminé, fixé par le dispositif de retardement. Cet agencement des lames permet une exécution sans danger et l'accumulation de l'énergie de rotation dans les lames permet de réaliser efficacement les opérations de coupe sur le matériau en vrac.
