摘要：
FIELD: agriculture； machine building.SUBSTANCE: invention relates to agricultural machine building, in particular, to machines for tillage of grain after harvesting of grain crops instead of peeling in order to reduce losses of moisture for evaporation, provocation of growth of weeds, reduction of power consumption of basic treatment of soil, leveling of soil surface in preparation for sowing. A tool for surface treatment of soil after harvesting of grain crops, comprising drums attached to the frame with a horizontal axis of rotation, located perpendicular to direction of movement, wherein the drums have teeth on the holders, and the drums are made hollow, on the external surface of which loosening teeth are fixed in rows along the helical lines, wherein teeth made in form of regular quadrangular pyramid have sharpening at angle of 12...15° and fixed to drum wall by means of thread for possibility of replacement, and for prevention of threaded connection disengagement there are spring washers, wherein teeth are installed by ribs in direction of movement and have height equal to required depth of treatment, hollow drums are installed on axes by means of sliding bearings and are mounted to coupler by means of mills, loosening teeth are fixed on external surface of drum along lines of multitrack propeller.EFFECT: proposed tool for surface treatment of soil after harvesting of grain crops.1 cl, 3 dwgИзобретение относится к сельскохозяйственному машиностроению, в частности к машинам для обработки почвы после уборки зерновых культур вместо лущения с целью снижения потерь влаги на испарение, провокации роста сорняков, снижения энергоемкости основной обработки почвы, выравнивания поверхности почвы при подготовке к посеву. Орудие для поверхностной обработки почвы после уборки зерновых культур, содержащее присоединенные к раме барабаны с горизонтальной осью вращения, расположенные перпендикулярно к направлению движения, причем барабаны имеют на держателях зубья, а барабаны в
