RESULTS OF EXPERIMENTAL RESEARCHES OF CLEANSING SYSTEM TO LOTS OF ROOT CROPS

Abstract

The article presents the results of field experimental tests of the modernized root-harvesting machine MKK-6, which is equipped with a combined system for cleaning fodder beets from various contaminants during their harvesting. Based on experimental results, regression equations are derived, which characterize the change of total contamination of heap of root crops with different impurities and graphical dependences of total contamination of heap of fodder beets, root damage, contamination of root crops with plant remains the diameter of the cleaning elastic elements. When analyzing the dependences, it was found that the total contamination of the heap of roots, depending on the angular velocity of rotation of the screw varies according to the parabolic function, which has a pronounced optimum. It is also reported that the main factor that affects the amount of sticky soil on the surface of the body of roots is the diameter of the cleaning elastic elements. With its increase, the amount of sticky soil on the body surface of the roots decreases significantly at all values ​​of the angular velocity of rotation of the screw.
