摘要：
The utility model relates to agricultural engineering, namely, devices for spreading mineral granular fertilizers on the soil surface.The technical result of the utility model is to increase the uniformity of fertilizer sifting due to the distribution of the redirected flow over the greater width of the main stream； to reduce the degree of crushing of fertilizer granules due to the direction of their impact plates of the sieving width limiting system at an angle close to the tangent； reducing sticking of wet fertilizers to the plates of the sieving width limiting device of mineral fertilizers due to the elasticity of the latter. The technical result is achieved due to the fact that the angle between the radii of the sector is 80 °, the radius of the smaller circle is 0, 05 m, and the larger - 0.25 m greater than the radius of the scattering disk, the louvre plates are made of elastic material, have the shape of a concave cycloidal surface with a radius of the rolling wheel R = 0.035 meters with the location of the inner end and at an angle of 30 ° with respect to the radius of the disk in the direction of its rotation, and their peripheral end is at an angle of 40 ... 70 ° with the radius of the disk towards rotation. A device for limiting the sifting width of mineral fertilizers, consisting of two identical, parallel to one another at a distance exceeding the thickness of the scattering disk with vanes, plates in the form of a circular sector bounded by two arcs of concentric circles facing an arc of a smaller radius toward the disk, connected by rigidly fixed perpendicular to their planes louvered plates oriented in plan at an angle to the radius of the disk, and the upper the plate is connected through a horizontal cylindrical hinge and a two-arm lever with a hydraulic cylinder for input and output of the device from the flight zone of fertilizer granules, moreover, that the angle between the radii of the sector is 80 °, the radius of the smaller circle is 0.05 m
