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.
