DEFINITION OF A MAXIMUM LOAD WORKING BODY OF A CLEANER OF ROOT CROPS
Keywords:
contact spot, modulus of elasticity, Tresk’s destruction criterion, maximal and minimal impulsive forceAbstract
The study reports on after-cleaning beet roots in the process of harvesting sugar beet crops is the proper preparation of the root crops for their digging. Preparation of root crops includes such operations as cutting of the main part of beet tops, after cleaning of the head of the root crop, etc. The solution of this issue is possible by solving the problem of high-quality after cleaning of root crop heads from the remnants of the root crops while saving the integrity of the productive part of the root. The efficiency of the work of the head cleaners of root crops determines the degree of separation of the beet tops remnants and the index of damage of the root crops. These are qualitative indicators and for their determination the dynamics of the interaction of working bodies of the cleanser with root crop should be done, taking to consideration the permissible stresses in the body of the root, based on the criterion of its strength, provided that the maximum separation of the remains of the beet tops. The research of the contact interaction of after cleaner’s of the working part of root crops with the conditions of the destruction of the remains of root tops under conditions of not damaging of the roots was carried out. The boundaries of allowed loads from are determined depending on the mechanical properties of the body of the root and the remnants of the beet tops, as well as their geometric dimensionsReferences
