FIELD: agriculture. ^ SUBSTANCE: method includes subsurface loosening with grinding and levelling of soil with working elements, capable of cyclic lift and lowering when coming across an obstacle. At the same time additional movement of working element is provided along trajectory having horizontal and vertical components, with simultaneous intensification of working element oscillations using elasticity force of additional elastic elements. Vector of resulting force of resistance of main elastic element is opposite to vector of resulting force of resistance of the first additional elastic element and has identical direction with vector of resulting force of elastic resistance of the second additional elastic element. Method is realised with device, which comprises working elements in the form of blades and/or disks serially installed on at least one frame. Device is equipped with at least one main elastic element installed at one side from axis of oscillations between and/or above frame and working element. Device also comprises at least one rotary mechanism connected with at least two additional elastic elements. At least one additional elastic element is installed relative to the main elastic element at the other side from axis of oscillations of working element between and/or above working element. Other additional elastic element is arranged at one side from axis of oscillations of working element with the main elastic element. ^ EFFECT: proposed technology and structural design will make it possible to intensity process of treatment and to improve quality of soil layer grinding into fine units, and also to increase reliability of device operation. ^ 3 cl, 8 dwg |
