摘要：
The utility model refers to agricultural machinery, in particular to the working bodies of discs and harrows. A cultivating spherical disk made of high-quality structural steel having a continuous cutting edge, a sharpening on the convex side of the working surface of the disk, and a hard-facing hardfacing layer, the hardfacing layer being made on the convex and concave sides of the working surface of the disk in the form of a series of identical arc- 2-4 mm, the concave side of the side surface of the weld beads is located in the direction of rotation of the spherical disc, and the opposite end faces of each Arc-shaped roller are located on different generators of the spherical surface of the disk, Wherein one end faces of the arcuate rollers are arranged along the length of the cutting edge at an equal distance from each other of at least 6 times the width of the deposited bead and the opposite end surfaces of the arcuate rolls are located at the intersection of the generatrixes of the spherical surface of the disk and the auxiliary circle parallel to the cutting edge Distance from the cutting edge is not more than 0.1 diameter of the spherical disk, the end surfaces of the arcuate rollers on the cutting edge of the concave side of the working surface These discs are located halfway between the end faces of the arcuate rolls deposited on the convex side of the working surface of the disc, the distance from the cutting edge to the auxiliary circle on the concave side of the working surface does not exceed 0.05 of the diameter of the spherical disc, And the number of weld beads is 2 times less than on the convex side of the working surface. The useful model makes it possible to reduce the wear rate of the working surface of a spherical disk by increasing the loosening intensity and reducing the density of the near-surface contact layer in the zones of the greatest friction intensity with compacted soil when it interacts with the surface of arc-shaped carbide rollers
