摘要:
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.
摘要:
A round bale wrapper for packing feed, like green forage and straw, intended for ensilage of the feed and conservation of the straw. The round bale is made to turn both about a substantially horizontal and a substantially vertical axis. The round bale wrapper comprises a round bale table (5), a chassis (10) with round bale table (5) being tiltable relative to the latter, and a packing sheet dispensing means (8) which is externally provided relative to round bale table (5). For continuous automatic packing of round bales the round bale wrapper comprises means (6) for clamping and cutting sheet (3) which is located between the round bale (1), and the sheet dispensing means (8). At a predetermined point of time or tilting angle during the tilting movement of round bale table (5) clamping and cutting means (6) operate sequentially. Upon cutting of the sheet (3) the latter is still firmly held in the clamping means, and the sheet is held during at least one revolution of the round bale table (5) as a first step of packing the next round bale.

The invention relates to a stretching means for braking a web of plastic sheet which is pulled off a reel. The stretching means comprises an arm (4) which is mounted to be slewable about an axis (5) extending in parallel with the axis (3) of said plastic sheet reel, a first roller (6) which is pivotally mounted on arm (4) and is intended to be made to rest against reel (2). Furthermore, the stretching means comprises a second roller (7) which is pivotally mounted on arm (4) to receive a loop of plastic sheet web (12) which is pulled off said reel (2) to cause said second roller (7) to be pulled towards said reel (2), and a drive connection (8) between said two rollers (6,7) causing the plastic sheet web to be stretched in zone (13) between the plastic sheet reel and the looped roller (7) when said web is pulled off the reel.

摘要:
A root crop harvester (10) comprising a forward crop-digger section (11), a conveying section (12, 15) arranged to receive material dug-up by the forward section (11) and to convey the material rearwardly to a discharge position (16) while carrying out at least partial separation of stone, clod and soil from the crop, and a roller separator device (25) arranged to receive material from the conveying section (12, 15) and to carry out further cleaning of the crop; in which the discharge end (16) of the conveying section (12, 15) is adjustable relative to the roller separator (25, 25a) between one position of adjustment (16a) in which there is maximum contact with the surfaces of the rollers (22) of the roller separator (25) suitable for heavy soil conditions, and a further adjusted position (16b) in which there is a reduced length of contact with the rollers of the roller separator.
摘要:
A bale wrapper apparatus for applying stretchable plastics film wrapping (in two or more stages) around a bale (14) which has: an axis of symmetry (15), a pair of opposed planar end faces (16) extending substantially perpendicular to the axis (15), and an outer surface (17, 18, 19, 20) extending between the planar end faces (16), and in which the apparatus comprises: a platform (30) for supporting the bale (14) with its axis (15) extending horizontally; a first travelling film reel support (21) movable in a horizontal plane along an orbital path (22) above the platform (30) and which applies one or more windings of the film around the bale (14) so as to cover the planar end faces (16) with one or more layers, and also to extending along the opposed sides (19, 20) of the outer surface of the bale between the planar end faces (16); a second travelling film reel support (24) which is movable in a vertical plane and along an orbital path around the axis (15) of the bale (14a) to apply windings of film around the outer surface (17 to 20) of the bale (14a); and means to cause relative longitudinal displacement between the bale (14a) and the second reel support (24) whereby helical overlapping windings of film can be applied to the bale to cover the outer surface (17 to 20) of the bale as a final wrapping stage.
