摘要：
The utility model relates to agricultural engineering, in particular to the working bodies of disc stubblers and harrows.Soil-processing spherical disk made of high-quality structural steel, having a cutting edge with cuts in the shape of a semicircle, a central hole, sharpening from the convex side of the working surface and a hardfacing layer of hard alloy with a hard-alloying layer 2-4 mm thick on the convex side of the working surface the disk is made in the form of identical arc-shaped rollers consisting of spot welds with a distance between points equal to the diameter of the weld point, opposite end surfaces of each A shaped roller is located on one forming disk spherical surface, one end surface of arcuate rollers are located on a parallel (auxiliary circle) parallel to the cutting edges of the spherical disk at a distance from the cutting edges equal to the width of the sharpening of the working face, and the opposite end surfaces of arcuate rollers on a parallel (auxiliary circle) parallel to the cutting edges of a spherical disk at a distance from the cutting edges are no more than the radius of the notch, the distance between the end surfaces of adjacent arc-shaped rollers, the concave sides of the side surface of which are opposite each other and the distance between the extreme points of the convex the sides of the side surface of the adjacent arcuate rollers on the axis of symmetry parallel to the cutting edges do not exceed 2-3 times the width s hard alloy layer arcuate platen.The utility model makes it possible to reduce the consumption of surfacing materials and the wear rate of the working surface of a spherical disk by increasing the intensity of loosening and reducing the density of the near-surface contact layer in areas of greatest friction intensity with compacted soil when it interacts with the surface of arc-shaped hard alloy rollers consisting of weld points on the weld thickness layer between adjacent cuts. 2 il.Полезная модель относится
