FIELD: agriculture.SUBSTANCE: ploughshare for pour plate seeding comprises a rolling cutter in the form of flat ring with cutting edge on the outer diameter and a seed drill tube. Cutter is equipped with a ditcher in the form of hollow truncated cones oppositely placed by larger bases, coupled with flanges in the form of hollow cylinders. Hollow truncated cones are replaceable depending on physical and mechanical properties of sown crop seeds. Flanges have grousers to prevent slipping the ditcher, a rolling cutter is installed on the post fixed to the seeder beam. Besides, the post is coupled with the wedge-like seed drill tube, and in its lower part, on adjustable supports, burying-press-wheel coverers are installed. Latter are mounted on the curved axis, which ensures their installation at an angle to horizontal plane with rim coverage of the outer edge of the groove made by a ditcher. Besides, chain harrow is secured to the curved axis with the help of leashes to create mulching soil layer above a seeded line.EFFECT: invention provides higher germinating ability of seeds and their economical consumption.1 cl, 2 dwg |
