ABSTRACT

The development of working bodies of selection machines is possible only under adequate study of physical and mechanical properties of seeds of specific varieties. The shape and size of seeds are variable and depend on the soil and the weather conditions during the growing season. The study of the size of seeds, their geometrical shape and their surface structure allows us to determine the nature of the interaction of single grain surfaces of the seed box, seed stem, the seed coulter reflector and the bounding surfaces and refine design parame-ters of selection grain drill. The objective of the work was to study physical and mechanical proper-ties of seeds zoned and promising varieties of crops of Tarsky district of Omsk region. The pur-pose was to determine the correlation between signs (linear dimensions) of seeds; to determine the angles of repose; to find out the coefficients of fric-tion of statistical seeds for various materials (steel, polyethylene, organic glass, and technical rubber). The following varieties of crops were investigated: wheat “Rosinka” and “Svetlana”; barley “Tarsky-3”; oats “Tarsky-2”. The linear dimensions of seeds determined using a micrometer with an accuracy of 0.01 mm. Humidity was determined according to the State standard 50189-92 “Grain”. Correlation dependence between variables (linear dimensions) seeds, installed angle of repose of cereal seeds were in the range of 29025//39012/; the coefficients of internal friction and static friction coefficients re-spectively were equal to 0.564-0.815 and 0,234-0.410.
