摘要：
The utility model refers to agricultural machinery, in particular to the coulters of stubble drills and can be used on grain seeders.The combination opener includes a lancet paw, a tuft-tube stand, identical hollow wedges and a vas deferens, a sole of the pointed paw, a funnel-guide, a flow divider with bridges, supply channels and a seed distributor. The stub-tube of the pointed paw has a rectangular cross-section, with a knife at the front surface of the tube-tu-gauge conduit of a height equal to the depth of seeding, with the angle at the tip of the knife equal to 60-65 °, while the lower part of the knife smoothly passes to the surface of the pointed paw . The edges at the vertex of the angle of identical hollow wedges are deflected backward relative to the direction of motion of the combined opener at an angle of 10 ... 12 °. The upper part of the funnel-guide coincides with the internal size of the cross-section of the column-track, while the bottom of the funnel-guide is connected to the divider of the flow of the fat, divided by two bridges into three equal parts, with three outlet openings forming in the lower part of the flow divider, with the bridges in the upper part of the flow divider entering the lower part of the funnel-guide by an amount equal to 1/2 the height of the funnel-guide. In the lower part of the funnel-guide, the jumpers are inclined towards the side walls of the funnel-guide at an angle not less than the angle of the natural slope of fertilizers. The supply channels connect the three outlet openings of the flow divider and the openings of the trihedral prism of the sole. In the lower part of the funnel-guide, the jumpers are inclined towards the side walls of the funnel-guide at an angle not less than the angle of the natural slope of fertilizers. The supply channels connect the three outlet openings of the flow divider and the openings of the trihedral prism of the sole. In the lower part of the funnel-guide, the jumpers are inclined to
