The present invention relates to a blower for a bean threshing machine and, more specifically, to a blower for a bean threshing machine capable of improving a structure of a blower attached to a bean threshing machine to be simple, thereby using a bean threshing machine for threshing different kinds of mixed grains such as sorghums, millets, or the like, adjusting the suction power of a blower in multi-stages by considering properties of a foreign substance even if the foreign substance of a bean is suctioned, applying to selection of different kinds of mixed grains by using excess suction power generated by driving of a blower, and maximizing the selection efficiency by adjusting suction power by considering the specific gravity of mixed grains to be selected when different kinds of mixed grains are selected. |
