成果简介	NOVELTY - The coulter has a stand (1) that comprises a cultivator paw (3), two shields (4), a seed tube (6) that is provided with a wedge-shaped diffuser with curved wings. The radius of curvature of the curved wings of the wedge-shaped diffuser comprises a width of one fourth of the width of the cultivator paw. The variable value is varied varying from a minimum of 15 mm to a maximum of 35 mm along the direction of movement of the scatter with transverse seed guide grooves made on the side surfaces of the scatter wings. Several longitudinal limiters are attached to the coulter shields. Two sowing strips are formed with a width equal to one fourth of the cultivator working width paws. A hollow fertilizer guide (9) with a cap made of a double-sided triangular wedge is fixed in front under the diffuser. A groove (8) is formed for mineral fertilizers in the center between two sowing strips below the level of the seeds. USE - Coulter for sowing seeds and applying mineral fertilizers. ADVANTAGE - The coulter increases the yield of agricultural crops due to strip sowing with the simultaneous incorporation of mineral fertilizers into the soil between the sowing strips below the level of the seeds. DESCRIPTION OF DRAWING(S) - The drawing shows a left view of the coulter for sowing seeds and applying mineral fertilizers.
