Abstract: The research object is the process of functioning of the excavating parts of a cultivating separating ripper, which transforms the structure and the density of a soil layer in accordance with the requirements of agronomical science for the cultivated crop. This result is achieved using the coordinated interaction of passive and active excavating parts. The machine also combs out the weed. The author considers the plowshare with steering disks, which spends less energy when moving through soil and directs soil to the separator. Theoretical researches are based on mechanical and mathematical modeling of interaction of the moving parts with soil. Experimental researches are based on the sectoral methods using strain-gage instruments and the methods of multifactor experiments planning. In the result, the process of soil cultivation using disk cultivating parts has been improved, the theory of justification of the parameters of active-passive cultivating parts for the separation and pulverization of soil and been developed; the mathematic model of interaction of cultivating parts with soil with account of energy intensity rates of technological processes has been composed. The use of methods of direct variational calculation for the justification of shapes of cultivating parts of a cultivating separating ripper helps reduce energy consumption by 10-30%. 


Keywords: movement through soil, shape of a plowshare, cultivating parts, separation, cultivating separating ripper, real tillage, secondary tillage, tillage with separation, steering disks, building-up
