Definitions

  • the present invention is related to an implement mount accessory for a vehicle, said accessory comprising an auxiliary axle in the vertical direction rotatably adapted close to the axle of the vehicle, actuator cylin ⁇ ders connected to said auxiliary axle and an implement mount platform rotatably attached to said auxiliary axle by means of an implement mounting part connected to said actuator cylinders.
  • the accessory comprises, attached to one axle of the powering vehicle or in the immediate vicinity thereof, a frame which is adjustable in the vertical direction relative to the vehicle and to which frame the mounting part of the frame is connected rotatably in the lateral direction relative to the vehicle. Then, the lateral position of the mounting part with the implement connected thereto is determined by the cooperation of the positions of the auxiliary axle and the vehicle axle closer to or farther away from the implement, while the longitudinal horizontal position of the mounting part is determined by the mutual relation ⁇ ship of the cooperation of the auxiliary axle and the vehicle axle closer to the implement and of the vertical position of the second axle of the vehicle.

Abstract

L'invention concerne un accessoire de montage d'un instrument d'agriculture pour un véhicule, comprenant un axe auxiliaire (3) monté rotatif dans le sens vertical à proximité de l'axe du véhicule (1), des vérins de commande (4, 5) reliés audit axe auxiliaire et une plate-forme (6) de montage d'instrument d'agriculture fixée rotative audit axe auxiliaire (3) au moyen d'une partie de montage (7) d'instrument d'agriculture, reliée audit vérin de commande. Afin de permettre le maintien de l'instrument sensiblement horizontal, ledit accessoire comporte un châssis (9) réglable dans le sens vertical par rapport au véhicule, relié directement audit axe du véhicule tracteur ou à proximité immédiate de celui-ci, et auquel ladite partie de montage (7) est reliée rotative dans le sens latéral par rapport au véhicule. Ainsi, la position latérale de la partie de montage à laquelle l'instrument est relié, est déterminée par les positions relatives de l'axe auxiliaire (12) et de l'axe du véhicule par rapport à l'instrument (plus près ou plus loin de celui-ci), alors que la position horizontale longitudinale de la partie de montage (7) est déterminée par la relation mutuelle de coopération entre l'axe auxiliaire (3) et l'axe vertical (2) plus près de l'instrument et de la position verticale du second axe du véhicule plus loin de l'axe auxiliaire.
