METHOD FOR SOIL TREATMENT, AERATION AND FERTILIZING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC A01C23/02 A01B49/06 A01B13/14 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to a method and device for soil treatment. Device comprises a main frame with suspension elements on various tractors of different draft class, system for feeding compressed air to deep tillers, system for feeding liquid fertilisers under pressure. On the frame, in front of and behind deep tillers there are mounted flat cutting working elements for horizontal treatment considering the overlap on rigid supports and with individual independent treatment depth adjustment. Deep tillers are mounted on the middle transverse bar-tube of the frame by means of holders with the possibility of their arrangement at different length of spaces between rows and oscillations in a longitudinal vertical plane with a defined frequency and amplitude, and have elements for feeding compressed air and liquid fertilisers into subsurface soil horizons. In the rear part of the frame there is a mounted packing wheel to adjust the deep tillers’ treatment depth, to grind and compact the upper soil layer.

EFFECT: method and device for soil treatment provide soil loosening, layer by layer, by means of deep tillers with oscillations in a longitudinal vertical plane and compressed air jets, as well as feeding liquid fertilisers, including by traces of running systems of tractors of different draft class, and working elements for horizontal soil treatment, loosening soil along the whole width of tool gripping and for compacting the upper soil layer, that provides high quality of soil treatment, reduced power consumption and increased service life of working elements.
