Abstract
A rotary combine including a feeder mechanism and a rotor assembly having an impeller assembly arranged at a forward end of a rotor. The feeder mechanism includes a housing which is pivotally connected to the combine about a transverse axis. The feeder mechanism housing envelops a conveyor assembly used to impart linear movements to the crop materials as they are advanced toward the rotor assembly. Prior to their introduction to the rotor assembly, the linearly advancing crop materials are discharged from a rotary member. A salient feature of the present invention involves the communicative relationship established between the rearmost rotary member from which the crop materials are discharged and the foremost end of the impeller assembly. The longitudinal spacial relationship therebetween is such that the crop material flow is permitted to transmute from the linear flow imparted thereto as the materials moved toward the rotor assembly and a rotary or circulatory flow imparted thereto as the materials are introduced to the whirling blades of the impeller assembly.
