| 摘要 |
This invention relates to a combined threshing machine and rotary separator for grain crops. The threshing and separator sections are disposed in axial alignment, with the proximal ends in substantial overlapping relation. Straw disposal means is located adjacent the distal end of the rotary separator section. Grain is removed on a conveyor at the bottom of the threshing section adjacent the proximal end of the separator. A blower is located below the conveyor outlet. The rotary separator section comprises three concentric cylindrical shells rigidly connected together for unitary rotation, the innermost shell being wholly perforated and provided with tumbling louvers on its inner surface. The intermediate shell is partially perforated and provided with deflecting louvers oriented to move threshed materials towards the perforated portion. The outermost shell is imperforate and has louvers on its inner surface oriented to move grains towards the blower and the grain trough disposed below the bottom side of the end of the outermost shell adjacent to the blower.
