Engineering of block for removing difficult-to-separate impurities from grain in separator with machine vision

Grain dockage with difficult-to-separate weeds, especially seeds of Tatar buckwheat (Fagopyrum tataricum), significantly impairs both the sowing and technological properties of grain. The seeds of Tatar buck-wheat are physically similar to wheat seeds, which makes it difficult to remove them using traditional cleaning methods such as sieve separators, pneumatic separation channels, triers and other separators. Purification of difficult-to-separate impurities is possible due to the use of modern technologies of machine vision. The article presents the results of engineering and demonstration of a hardware and software complex for automatic separation of difficult-to-separate weed impurities, in particular seeds of Tatar buckwheat.
