International ClassA01D 034/07Foreign Application Priority Data1997-11-20 DEAbstractA combine harvester has a mounted chopper with a wide-distributor discharge, designed such that the need for impeller blowers for distributing the chopped material across the entire cutting width of the combine harvester is eliminated.In the mounted chopper according to the invention, the latter consists of the two chopper units whose shafts carrying the chopper blades are at an obtuse angle to each other and cooperate with corresponding counterblades. Each chopper unit is equipped with an input funnel so that the straw is chopped completely. To distribute the chopped material, each chopper unit is equipped with an ejection fitting, increasing in cross-section towards the rear end.The mounted chopper is particularly suitable for combine harvesters with a wide cutting width. | |
