Modelling Wheat Grain Flow During Sowing Based on the Model of Grain with Shifted Center of Gravity

Abstract Winter wheat is one of the widespread crops in Ukraine. The search for methods to increase yield and consumer properties wheat, without compromising environmental safety, important scientific problems. principles precision agriculture point proper positioning seeds, recommending method “upward germination” (positioning germ vertically). main objective this study was develop a new geometric model grain with displaced centre mass, as well conduct theoretical research numerical experiments on orientation grains using their multiple impact interaction inclined surfaces. A consisting two different end semispheres amid-line truncated cone proposed, mass. Taking into account physical objects, concept arrangement gravity seeds stream applied. This based various ratios kinetic parameters bodies following an impact. results showed that process can be controlled by changing inclination angles length walls tray orientator within working velocity range. must done before 0.2-0.3 m s −1 when planes are 24-32°C.
