Ryzhiy A. Substation of parameters of multi-tier agrimeliorative ripper

Object of research: process of deep level-by-level cultivation of soil and technical devices for its realization; the aim: improvement of quality deep cultivation of soil due to development and use of process doubleareaed deformation of a layer by soil-cultivating part and substantiation of parameters of multi-tier for its realization; methods: the agricultural mechanics, mechanics of utter ambience, theory of elasticity and plasticity; novelty: for the first time models of process doubleareaed deformation of a soil layer by soil-cultivating part and transversal surface of soil-cultivating part are analytically elaborated; the rational correlation of thickness both width of a soil layer and radius of initial cutting of a transversal surface, which provide better quality, are experimentally determined; results: the experimental sample of multi-tier agrimeliorative ripper is elaborated; is introduced in collective farm "Infor-centre", Rivne region; sphere of use: agro-industrial complex of Ukraine.
