FIELD: agriculture. ^ SUBSTANCE: device contains frame, rigidly installed tubular posts with fixed on them working elements and distributors of fertilisers. Device has augers with drive unit located in cups. Cups are connected by flanges with tubular posts fixed on the frame by means of welded to frame brackets and equipped with slide valve to regulate dose of applied fertilisers. In accordance with the first version working elements are made in form of rigidly fixed on tubular posts flat discs with tubular distributors of fertilisers with slot made on tube element. According to the second version working elements are made in form of pivotally fixed on posts conic discs, separated into spiral-shaped sectors with two surfaces. The first surface of sectors has sharpening and smaller angle of ascent than the second one. Distributors of fertilisers of working elements in form of conic discs are made conical. ^ EFFECT: mentioned constructive implementation will allow to increase wear-resistance of working element, extend technological possibilities of the device, improve quality of distribution of fertilisers. ^ 4 cl, 6 dwg |
