Abstract
Abstract Due to the high energy intensity of lifting of deep-seated table root crops, their growth develops mainly in light sandy-loam soils, in which it is possible to transfer a heap of root crops to the separating devices in order to facilitate the qualitative separation. Therefore, issue of lifting of deep-seated table root crops at minimal energy consumption and labour costs is an important scientific and practical task, which would allow expansion of cultivation of deep-seated table root vegetables to heavy soils. Research was conducted by means of a theoretical method utilizing elements of theoretical mechanics with subsequent processing of results by means of PC. Mathematical model and resulting energy cost dependences were constructed on the basis of the device parameters for soil loosening and lifting of deep-seated table root crops. Refined mathematical model of the process of lifting of deep-seated root crops made it possible to find out scientific and technical preconditions for the development of lifting devices with minimal energy consumption.
