The invention relates to agricultural agricultural mechanical engineering and is intended for surface soil cultivationduring the presowing period of crops and seedlings of trees cultivation. The essence of the device for presowing soil cultivation: the device contains operating devices in the form of paws and/or disks sequentially established on, at least, one frame with possibility of lifting and lowering them concerning a frame at a meeting with an obstacle, provided by, at least, one basic elastic element established on one side of an axis of oscillation between and/or over a frame and operating device. Besides, the basic elastic element is done in the form of, at least, two elastic plates and/or a bar, or a set of plates and/or bars of identical or different width and/or thickness, the device contains an additional elastic element with, at least, two elastic plates and/or a bar, or a set of plates and/or elastic bars of identical or different width and/or thickness, located opposite an axis of oscillation of operating device and connected with, at least, one rotary mechanism. The inventive device provides the intensification of process of soil cultivationand improvement of quality of crushing of a layer of the soil on small units, and also increases reliability of the device operation. |
