JUSTIFICATION OF RATIONAL CONSTRUCTIVE-KINEMATIC PARAMETERS OF WORKING BODIES OF ADAPTED ROOT COLLECTING MACHINES

Abstract

Pruning, digging and cleaning of roots 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 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 of a hyphen, digging and clearing modules of self-propelled root harvesters are regulated by dimensional parameters and the form of root crops and physical and mechanical condition of amniotic soil environment. The obtained theoretical mathematical models (1) and (2) and empirical dependences (3) - (7) can be used for further development and substantiation of rational constructive-kinematic parameters of working bodies of adapted root-harvesting machines. 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, up to 90 g for table beets, up to 65 g for carrots, 20… 360 g for chicory roots.
