The article presents, based on research into the impact of military operations on agricultural soils, the design of a flexible screw sectional working body, which will allow to increase the functional and operational characteristics of screw conveyors during the disposal of the removed contaminated soil layer. For the research, an experimental setup was developed and manufactured, with the help of which the torque on the drive of the flexible screw conveyor was determined. Based on the results of the research, graphical dependences of the change in the value of the torque Т on the frequency of rotation of the drive shaft of the working body n, on the radius of curvature Rк of the technological line and on the height h of movement when the technological line is completely filled with loose cleaned damaged soil from the middle of the crater are constructed. The obtained research results make it possible to choose the optimal design, kinematic and technological parameters of the developed screw sectional working body for transporting loose cleaned damaged soil from the middle of the crater.

An actual problem in the technological process of table beet production is the cleaning of root crops from adhered soil, soil impurities and plant residues after digging them out of the soil. In this paper we have constructed a mathematical model of table beet root crop movement along the working channel of the new construction of the spiral separator developed by us, because at such movement just the cleaning of root crops from these impurities takes place. On the basis of the equivalent scheme developed in this article, a system of differential equations of motion of table beet root crop along the surface of the working channel of the spiral separator is drawn up. The solution of the obtained system of differential equations on the PC makes it possible to investigate the influence of constructive and kinematic parameters of the separator on the speed of movement of the root crop in the working channel before its descent from the spirals. Thus determined constructive and kinematic parameters will provide improvement of the quality of cleaning of table beet root crops from soil impurities and plant residues.
