EXPERIMENTAL RESEARCH OF ROOT HARVESTING MACHINE AND METHODS OF ANALYSIS OF RESULTS

Abstract

Abstract. Digging and cleaning of root crops from impurities depends not only on the design and parameters of the working bodies of the root harvesting machine, but also on the agrobiological and physical and mechanical characteristics of root crops during their harvest. The efficiency of pruning, digging and cleaning of root crops from impurities depends not only on the design and parameters of the working organs of the root harvesting machine, but also on the agrobiological and physico-mechanical characteristics of roots during harvesting. The choice of design of working bodies and adjustment of parameters and modes of operation of the module for cutting the buds, digging and cleaning modules of self-propelled root harvesters are regulated by dimensional parameters and shape of roots and physical and mechanical condition of amniotic soil. The results of experimental studies of the mass and thickness of the layer of sticky soil on the body surface of excavated roots depending on their dimensional characteristics and physical condition of the soil are presented. It is established that the mass of sticky soil varies from 10… 220 g for fodder beets, 35… 290 g for sugar beets, to 90 g for table beets.
