Threshing device for harvesting machines

A threshing device for harvesting machines, the harvesting machine having a cut front header for cutting plants to be harvested, the threshing device comprising:

• a feeder rotor, wherein the cut front header conveys the cut plants to the feeder rotor;
• at least two threshing rotors, wherein the threshing rotors are placed adjacent to each other and only one is located adjacent to the feeder rotor, wherein the feeder rotor feeds the plants to the threshing rotor nearest the feeder rotor, wherein all threshing rotors turn in the same direction;
• wherein each threshing rotor comprises:
• a shaft;
• a manifold of threshing wheels;
• wherein each threshing wheel is connected to the shaft of the corresponding rotor;
• wherein the threshing wheels are laterally separated from each other;
• wherein each threshing wheel is intercalate between the wheels of the adjacent threshing rotor;
• wherein each one of the wheels of the threshing rotor comprises groups of projections of equal distance distributed over the perimeter of the wheel, wherein each group of projections define a mixer;
• wherein the groups of projections are parallel to each other and longitudinally bent with regards to the turning sense of the corresponding threshing rotor;
• and
• a grille located underneath of the threshing rotors, wherein the grille runs continuously through all the threshing rotors and includes a plurality of waves parallel to each other and defining peaks and valleys, wherein the valleys match the peaks of the adjacent waves, wherein on each valley the corresponding threshing wheel is located.
