Machine support device especially for agriculture, arboriculture and viticulture

摘要

The support comprises a mast pivoted by an actuator, with retaining arm pivoted by the actuator around a trunnion on a sleeve sliding on the mast, and height adjustment accomplished by the third actuator. The viticulture machine support comprises a mast (10) able to pivot around a shaft (11) in its lower part under the action of a hydraulic actuator (60). A retaining arm (40) is able to pivot around a trunnion (24) fixed on a sleeve, able to slide on the mast, under the action of a hydraulic actuator (70). The actuators are located at the top and bottom and on either side the mast axis so that the machine trim is automatically conserved during mast pivoting. Height adjustment of the machine is accomplished by an actuator (80) whose lower articulation shaft (81) is carried by a support (13) and its upper articulation shaft is connected to a support integral with the sleeve. A balancing pole (30) comprises rear (32) and a front (33) seats between which is a tubular element (31). The arms can be arranged on the front seat at different heights. The balancing pole is pivoted on a trunnion (24F) on the sleeve.
