(or) the displacement control mechanism 510a of hydraulic variable motor 530a around revolution fulcrum 520a be rotated in a clockwise direction when, forage folder
Tight roller diminishes fixing roller 120 and the rotating ratio of cutting roller 140, and the staple fiber ppd of ensilage reduces；Work as hydraulic variable displacement pump
The displacement control mechanism 510b of 530b is rotated in a clockwise direction around revolution fulcrum 520b, and (or) hydraulic variable motor 530a
Displacement control mechanism 510a around revolution fulcrum 520a rotate in the counterclockwise direction when, forage pinch roll is to fixing roller 120 and cutter
The rotating ratio of roller 140 becomes larger, the staple fiber ppd increase of ensilage.
As shown in Figure 1, a kind of control method of adjusting ensilage staple fiber ppd of the present invention is as follows：
When the staple fiber ppd for wishing silage harvester becomes in short-term, it is necessary to the displacement control mechanism of hydraulic variable displacement pump 530b
510b rotates in the counterclockwise direction around revolution fulcrum 520b, and (or) the displacement control mechanism 510a of hydraulic variable motor 530a around
Revolution fulcrum 520a is rotated in a clockwise direction, so as to reduce the rotating ratio of hydraulic variable displacement pump and hydraulic variable motor, that is, is increased
The rotating speed of cutting roller 140 reduces rotating speed of the forage pinch roll to fixing roller 120, and then meets that ensilage staple fiber ppd shortens
Control requirement.
When the staple fiber ppd for wishing silage harvester is elongated, it is necessary to the displacement control mechanism of hydraulic variable displacement pump 530b
510b is rotated in a clockwise direction around revolution fulcrum 520b, and (or) the displacement control mechanism 510a of hydraulic variable motor 530a around
Revolution fulcrum 520a rotates in the counterclockwise direction, so as to increase the rotating ratio of hydraulic variable displacement pump and hydraulic variable motor, that is, reduces
