摘要：
FIELD: agriculture machine building.SUBSTANCE: invention relates to agricultural machine building. Device contains wedge-shaped racks with fertilizer hoses mounted on their rear parts. Wedge-shaped racks are mounted on the frame, which has a suspension gear in the front part, and in the upper part has fertilizer dispensers, equipped with meters, hermetically connected with the fertilizer hoses. Wedge-shaped racks that serve as the chisel tools are fixed to the frame by articulated axles, while on the frame to the lower part behind the wedge-shaped racks stops are welded, in the groove of which the compression springs are mounted. Before the wedge-shaped racks, the stops for mounting shock absorbers from elastic material are welded to the lower part of the frame. Front part of the wedge-shaped racks has a sharpening, a cutting edge of which is made along a parabolic curve of an equation y=2x3, where y is the vertical coordinate of the equation x is the horizontal coordinate of the equation. Rear part of the wedge-shaped rack has a fertilizer hose with injectors in the lower part. Wedge-shaped racks are installed on the frame crossmembers, one wedge-shaped rack on the front crossmember, on the second crossmember there are two wedge-shaped racks, on the third crossmember there are four wedge-shaped racks, distance between crossmembers , where a – processing depth α – the angle of blade installation of the wedge-shaped rack to the horizontal plane (angle of crumbling) γ – the angle of soil friction along the steel ρ – the angle of soil friction along the soil l0 – the value determined by the design of the wedge-shaped rack, the width of the traces M = 400…500 mm. Distance between adjacent racks in one row t>0.5(2a+b), where a is the depth of cultivation b is the working width of the wedge-shaped rack. For adjusting the depth of the cultivation, depth wheels and a meter drive are provided, and the formation of a fertilizer-air mixture is made from a high-pressure fan ha
