FIELD: agriculture; machine building.SUBSTANCE: section comprises disc knife in form of flat ring with cutting edge on external diameter fitted with furrow former, seed tube. Furrow former is made in form of opposed larger bases of hollow truncated cones. Furrow former cones are made replaceable, depending on physical-mechanical and biological properties of sown crop. Behind disk blade equipped with furrow former, there are two circular blades with flanges. Flanges are made in form of hollow truncated cones arranged with large bases to disk knife. Edge of small bases of cones is placed over outer edge of the furrow made by furrow former. After furrow former there is seed tube, which lower part is arranged in furrow is made as anchor. Behind disk blades with flanges fertiliser tubes are arranged, which lower part located in furrow, formed by disk knife is made of anchor. Disk blades and furrow former are installed on brackets fixed to posts. Posts are mounted on beam connected to parallelogram hinge with possibility of adjustment in horizontal plane.EFFECT: such design will allow to enhance seeds capacity and crop capacity due to availability of mineral fertilisers for root system of plants.1 cl, 2 dwg |
