FIELD: agricultural engineering.
SUBSTANCE: invention relates to agricultural engineering, namely to forage harvesters equipped with a feeding device, designed for pre-pressing the plant mass coming from the header or pick-up, and feeding it into the shredding device. The device includes a feeder frame, two lower, ribbed and smooth, rollers, two upper pre-pressing toothed rollers, an adapter fixing mechanism, a drive mechanism and a pre-pressing mechanism, which includes levers and springs with a hinge. On the feeder frame, due to two roller assemblies in the upper part and one roller assembly in the lower part, a rectangular transverse copying frame is fixed, which includes two supporting rods, a hydraulic cylinder and an adapter fixing mechanism.
EFFECT: provides pre-pressing of the plant mass and its feeding into the shredding apparatus.
