Abstract
Un dispositif de travail agricole destiné à être monté à l'avant d'un tracteur est constitué de manière que sa monture (12) puisse s'adapter aux inégalités du sol en pouvant non seulement se déplacer vers le haut et vers le bas et pivoter autour d'un axe longitudinal dans le sens de la marche, mais également qu'elle soit reliée au châssis porteur (5) et puisse pivoter avec les outils de coupe (13) autour d'un axe transversal. On obtient cette possibilité de pivotement autour d'un axe transversal d'une façon simple en munissant de fentes de guidage (7, 11 ou 15, 17) les bielles (8, 9) qui réalisent la liaison entre le châssis porteur (5) et la monture (12) du dispositif.An agricultural working device intended to be mounted on the front of a tractor is constructed in such a way that its mount (12) can adapt to unevenness in the ground by being able not only to move up and down and to pivot. around a longitudinal axis in the direction of travel, but also that it is connected to the supporting frame (5) and can pivot with the cutting tools (13) around a transverse axis. This possibility of pivoting around a transverse axis is obtained in a simple manner by providing guide slots (7, 11 or 15, 17) on the connecting rods (8, 9) which provide the connection between the supporting frame (5) and the frame (12) of the device.
Description
Dispositif de travail agricole destiné à être monté à l'avant d'unAgricultural working device intended to be mounted in front of a
tracteur L'invention concerne un dispositif de travail agricole destiné à être monté à l'avant d'un tracteur, comprenant un châssis porteur et une monture reliée à ce dernier par des bielles, la monture étant reliée de façon mobile au châssis porteur perpendiculairement et autour The invention relates to an agricultural working device intended to be mounted at the front of a tractor, comprising a support frame and a frame connected thereto by connecting rods, the frame being movably connected to the carrier frame perpendicularly and around
d'un axe longitudinal situé dans le sens de la marche. a longitudinal axis in the direction of travel.
Un dispositif de ce type est décrit et montré par exemple dans le document DE-A-3 022 742 Il s'agit dans ce cas d'un mécanisme de moisson avant grâce auquel les outils de ce dernier peuvent suivre de la meilleure manière possible les inégalités du sol Pour atteindre ce but, la monture du dispositif est suspendue de manière que les outils du mécanisme de coupe puissent se déplacer aussi bien vers le haut que vers le bas, et en outre effectuer un mouvement de rotation autour d'un axe longitudinal situé dans le sens de la marche S'il est nécessaire de passer avec un dispositif de ce type sur des ondulations du sol qui sont transversales au sens de la marche, les outils de travail ne peuvent se déplacer que vers le haut et vers le bas et n'ont pas la possibilité de s'adapter à la partie montante ou descendante des ondulations du sol en se mettant dans une position en oblique La coupe est alors de mauvaise qualité aussi bien dans les montées que dans les descentes Pour éviter ce résultat, il convient qu'un dispositif du type indiqué dans le préambule dispose entre le châssis porteur et sa monture d'une possibilité de tourner autour d'un axe transversal Ceci permet aux outils de coupe ou autres outils de forme plate de se disposer en oblique quand ils passent sur des ondulations du sol, de A device of this type is described and shown for example in the document DE-A-3,022,742. In this case it is a harvesting mechanism before which the tools of the latter can follow in the best possible manner the unevenness of the ground To achieve this purpose, the mount of the device is suspended so that the tools of the cutting mechanism can move upwards as well as downwards, and further rotate about a longitudinal axis in the direction of travel If it is necessary to use a device of this type on ground waves that are transverse to the direction of travel, the working tools can only move up and down. and do not have the possibility to adapt to the rising or falling part of the undulations of the ground by putting oneself in an oblique position The cut is then of bad quality as well in the ascents as in the descents To avoid To this end, a device of the type indicated in the preamble should have a possibility of rotation about a transverse axis between the carrying frame and its mount. This allows the cutting tools or other flat tools to arrange obliquely when they pass over undulating soil,
manière à pouvoir suivre les rampes montantes ou descendantes. so that you can follow the rising or falling ramps.
Selon l'invention, l'un au moins des points de rotation des bielles effectue, en dehors d'un mouvement de rotation, un mouvement According to the invention, at least one of the rotation points of the connecting rods performs, apart from a rotational movement, a movement
