Crop reinjection chamber

摘要

A forage harvester having a rotary reel cutterhead disposed within a housing to operate against a shear bar, peripheral shielding being disposed on the inlet side of the cutterhead except for a material entry gap in the region above the shear bar is provided with a crop reinjection chamber disposed in the peripheral shielding immediately above the material entry gap, the chamber comprising a transversely extending cavity wherein the cavity wall in the direction of rotation includes an arcuate portion for redirecting the flow of crops escaping the cutterhead periphery back into the cutterhead at a substantial angle to the cutterhead periphery.
