摘要：
The proposed utility model relates to agricultural engineering, namely, devices for scattering mineral granular fertilizers on the soil surface. The technical result of the proposed utility model is to increase the uniformity of sieving of various fertilizers due to the possibility of regulating the shape of the working surface of each blade. The technical result is achieved due to the fact that 0.05 meter blades protrude beyond the edges of the disk, have a variable thickness that gradually decreases to the periphery of the disk, nor the end surface is in contact with the surface of the disk with the possibility of sliding on it, from the inner end, rigidly, for 0.06 meters, attached to the disk with a backward bend at an angle of 45 ° to its radius, and from the peripheral end the back surface is rigidly attached to the pin, the lower threaded part of a smaller diameter which is fixed in the oblong radial hole of the disk with a nut and washer. The centrifugal working body for sieving fertilizers is operated as follows. Before work, depending on the type and moisture content of a particular fertilizer, the corresponding curvature of the working surface of each blade is established using the reference table obtained experimentally, moving the pin along an elongated hole and fixing it with a nut and washer. When working, the fertilizer granule falls onto the disk and moves across the disk until it meets with a scapula at its beginning. Due to the installation of the working surface of the blade with a backward bend at an angle of 45 ° with respect to the radius of the disk, the force of impact of the granule about it decreases. Further movement occurs along the blade until it completely leaves the disk with an absolute speed V. Due to the different curvature of the blades being set, the peripheral end of their working surfaces is at different angles ϕ to the radius of the disk and the velocity vector V of the fertilizer granules coming down from each blade has a dif
