But the wind separation efficiency and the wind separation accuracy of a single device are not solved.

Patent 207252766U a combined type wind divider improves the wind efficiency of back-stage wind divider through reducing material flow to improve the total wind efficiency of a dozen back wind dividers combination, reduce a dozen back wind dividers configuration quantity simultaneously, realize energy saving and consumption reduction's purpose. The patent also solves the problems of air separation precision and efficiency through the combined allocation idea.

The working state of a single air separator directly determines (influences) technical indexes (quality) and economic indexes (energy consumption) of the threshing air separation production line, so that the air separation precision and efficiency of the single air separator are the core technology for separating the leaf stems.
