摘要：
FIELD: agriculture； engineering.SUBSTANCE: invention relates to the field of agricultural engineering, in particular to tools for introducing seeds and fertilizers into the soil. Combination opener comprises a stand with a neck, funnel and with an angle of 10…12° to each other with two discs. Fertilizer guide for inserting the main dose of fertilizers into the notch cut by the discs is fixed to the stand of the combined coulter with the reinforced stiffener of the bracket, which is installed at the place of attachment of the internal cleavers of the combined opener. Upper part of the bracket, located above the bracket attachment point to the stand, has a shelf bent at right angles to the plane of the bracket. Lower part of the guide is bent backwards in the direction opposite to the movement of the combined opener, along an arc of a circle of radius R = 300 mm and has an outlet located in a transversely vertical plane directed with respect to the longitudinal-vertical symmetry plane of the combined opener, and in the horizontal plane coinciding with the lower part of the cutting edges of the two discs of the combined opener. Upper part of the guide has two ears, the end surface of which is parabolic, identical to the end surface of the lower part of the funnel of the neck of the column so that it fits snugly against it. Seed drill tube for introducing seeds together with the starting dose of fertilizers has in the upper part a neck, made with it as a single unit and from a tube with a diameter of 40 mm, and also fixedly fixed to the shelf of the bracket. Lower part of the seed drill tube is also bent backwards, opposite to the movement of the combined vomer along an arc of a circle of radius R = 300 mm. In the lower part, the seed drill tube has an outlet located in a transverse-vertical plane directed with respect to the longitudinal-vertical symmetry plane of the combined vomer. Following the fertilizer guide there is a seed bed sealer installed under the outlet h
