COMBINED AGGREGATE FOR SOIL PROCESSING AND APPLICATION OF LIQUID FERTILIZERS Russian patent published in 2009 - IPC A01B49/06 A01C23/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine-building, in particular to technical means for soil tillage, mechanical elimination of weeds, earthing up plants with simultaneous intra-soil or superficial application of pesticides or root or non-root additional fertilizing of plants with liquid fertilizers. Combined aggregate contains transverse bar with centrally located system of hitching on tractor fixed on it on one side, and support wheels fixed by means of brackets, and on the other side of transverse bar, fixed by means of parallelogram mechanism, sections, each of them including copying wheel and equipped with extender longitudinal beam with operating elements installed on it. Support wheels are fixed by means of adjustable supports on longitudinal cantilevers installed in end parts of transverse bar, from two sides of which in region of supporting wheels pair brackets are additionally fixed on which there are support sites for installation of removable reservoirs with liquid fertilizers, reservoirs being connected with aggregate system of fertilizers distribution, sections are evenly distributed on transverse bar, and longitudinal beam is cantileverly fixed on free lower end of vertical elongated link of parallelogram mechanism, copying wheel is fixed above beam on vertical elongated link with possibility to regulate its position, each beam being made in form of U-shaped box equipped with mounting elements made in form of small front, large middle and small back, successively located in box bottom, longitudinal rectangular windows, and sidewalls of the box are equipped with co-axially located slot cuts and holes of square form, and inside the box along both longitudinal sides of front and back small rectangular windows profile stocks with holes are fixed with beam extender equipped with hole, and on each beam there are fixed replaceable soil-processing tools or S-shaped spring posts with hoes and chisel-shaped ripper with sprayer, connected by pipeline with system of fertilizers distribution, or A-hoe blades, or right or left single-sided subsurface cultivators or chisel-shaped rippers, or combined operating elements made in form of hoes, fixed on vertical posts equipped with installed on them removable double-sided blades with removable pinnate extenders.

EFFECT: invention solves technical problem of extension of aggregate functional possibilities, increase of its productivity and versatility, improvement of mounting and dismantling of operating elements, improvement of quality of crop cultivation, increase of efficiency of soil processing, weeds destroying and additional fertilizing of cultivated crops, increase of reliability of technological process progress.
