Feed device for a chopper of a forage harvester

摘要

The invention relates to a feed device for a chopping device of a forage harvester with lower stationary feed rollers (8, 10) and vertically movable upper feed rollers (12, 14) mounted on rockers (18, 22) which, during operation, move downwards towards the lower feed rollers (8 , 10), thereby pre-pressing a crop flow and feeding it to a chopping drum (4) of the chopping device, with at least one of the upper feed rollers (12, 14) being pressed down by the force generated by one or more hydraulic cylinders (5) and with the The force of the intake roller (14) directly adjacent to the chopping drum (4) is generated with at least one hydraulic cylinder (5) which is or are directly articulated to the rocker (18) or the rocker of this intake roller (14) and the hydraulic cylinder or cylinders ( 5) is or are subjected to a constant hydraulic pressure over the entire deflection movement of the feed roller (14).
