Title (EN) DEVICE FOR WORKING THE GROUND
(FR) DISPOSITIF SERVANT A TRAVAILLER LA TERRE
Abstract:
(EN) A device (1) for working the ground comprises a frame (2) and a plurality of discs (6). Each disc is rotatably mounted on a lying shaft (5) which is provided on the free end of a pivotable standing shaft (4). In order to prevent jamming of the discs (6) by earth thrown up by adjacent discs (6), each standing shaft (4) is placed on the concave side of its associated disc (6). The lying shafts (5) are inclined relative to the ground, thus providing an improved ''digging'' working of the ground. The slope of the shafts (5) relative to the ground can be varied by pivoting a part (26) bearing the standing shafts (4) relative to a fixed part (25) of the frame (2).
(FR) Le dispositif (1) servant à travailler la terre comprend un châssis (2) et une pluralité de disques (6). Chaque disque est monté pour la rotation sur un arbre horizontal (5) muni à son extrémité libre d'un arbre vertical (4). Afin d'empêcher que les disques (6) ne soient engorgés par la terre rejetée par les disques voisins (6), chaque arbre vertical (4) est placé du côté concave du disque (6) qui lui est associé. Les arbres horizontaux (5) sont inclinés par rapport à la terre afin qu'ils travaillent la terre ''en creusant''. On peut modifier l'inclinaison des arbres (5) par rapport à la terre en pivotant un élément (26) porteur des arbres verticaux (4) par rapport à un élément fixe (25) du châssis (2).
