摘要：
FIELD: agriculture.SUBSTANCE: invention relates to agricultural machinery industry, in particular to devices for internal application of crushed organic and dissolved mineral fertilisers in the root layer of soil. The combined fertiliser distributor comprises a hopper, which comprises a feeding horizontal conveyor, behind which at the output side a grinding drum is mounted, equipped with toothed elements arranged along the helical lines. The toothed elements are made segment-like, the front cutting edge of which is made along the Archimedean spiral with an angle of blade sharpening of 15-20°. Under the grinding drum there is a height adjustable concave with segment-like toothed elements set in a staggered manner, the front cutting edge of which is made parabolic with an angle of blade sharpening of 15-20°. Behind the grinding drum using leashes, pivotally attached to the frame of the hopper at a distance equal to half the diameter of the drum, a needle drum is mounted, controlled by the hydraulic cylinder and deepened by the compression spring. Behind the needle drum on the bracket-extender a water-conducting collector is attached, with the sprayers of directional action. For supplying the liquid to the collector there are water-conducting hoses connected hydraulically to the tanks filled with a solution of mineral fertilisers or water. On the water-conducting hoses the control valves are provided. The drive of the grinding drum is made from a tractor PTO shaft through a gearbox.EFFECT: with this implementation the quality of grinding is improved, uniform distribution of organic and mineral fertilisers in the root layer of the soil, which increases soil fertility and crop productivity.2 dwgИзобретение относится к сельскохозяйственному машиностроению, в частности к устройствам для внутреннего внесения измельченных органических и растворенных минеральных удобрений в корнеобитаемый слой почвы.
