Abstract

Aim. To work out the substantive provisions of theory of oscillation excavation of root crops of beets saccharine on the basis of consideration of shock co-operation of excavation of working organ with the body of root crop of beet that is contained in soil, and to get on their basis the parameters of process, that will provide the undamage of root crops. Methods. Analytical researches of oscillation excavation of root crops of beets saccharine are carried out on the basis of mechanico-mathematicaldesign of process, in particular theories of mechanical blow. Results. The theory of shock co-operation of excavation ploughshares of oscillation digger is worked out with the body of root crop of beet saccharine at his asymmetric delight. Analytical expressions of frequency of vibrations of excavation ploughshares, at that the terms of undamage of body of root crop are executed are got. The numerical decision of got on PEC of equalizations gave an opportunity to define the structural and kinematics parameters of oscillation excavation of working organ, at that there is not a damage of bodies of root crops of beets saccharine for their excavation from soil. Conclusions. The equivalent chart of oscillation excavation of root crop of beet saccharine is worked out on the basis of consideration of shock co-operation of body of root crop with a ploughshare, when the delight of root crop takes place asymmetric, id est their contact comes true only in one point, taking into account all forces that arise up at such contact. On the basis of general theory of blow the theory of oscillation excavation of root crop of beet saccharine is created from soil for terms, when shock co-operation does not cause the damages of bodies of root crops of beets. A numerical decision on PEC of the got analytical dependences gave an opportunity to define possible frequencies of vibrations of oscillation excavation of working organ.
