| 摘要 |
The invention relates to forage harvester (10) comprising a chopping mechanism (22) and a reworking device located downstream of the chopping mechanism (22) for corn tumbling that includes two rollers (28), between which the harvested crop chopped using the chopping mechanism (22) passes, and adjustment of the distance between the rollers (28) and/or their pressing force is provided by means of an actuator (50) connected to a control box (48) and controlled by the control box (48), wherein the control box (48) is able to receive information relating to the appropriate cutting length of the harvested crop cut by the chopping mechanism (22), to control the actuator (50) according to cutting length , and to adjust the distance between the rollers (28) and/or pressing force with which one roller (28) presses the other roller (28), characterised in that the control box (48) is able to control the actuator (50) so that the actuator (50) changes the distance between the rollers (28) and/or increases pressing force with an increase in the length of cutting of the harvested crop. |
