Phie. 1 The invention relates to agricultural machinery, in particular to machines for harvesting root crops. Known digging the working body of the harvester, containing digging discs and gear for drive disks 1. The disadvantages of the known working body are that it is complex in design and during its operation part of the root crops is lost due to damage from the discs rotating at different speeds and misses of the root crops because the discs are weakly coupled to the undermined mass. Known for digging the working body of a root-harvesting machine, containing pairwise-mounted inclined spherical disks having povazatechami and installed by means of the axes on the rack 2. The disadvantage of this working body is that it is complex in design and during its work some of the roots are lost. In addition, during operation, the scoops stick together and additional energy is required to insert the discs into the soil. The purpose of the invention is to simplify the design of the digging tool, to reduce the energy intensity of the process and the loss of root and tuber crops during harvesting. This goal is achieved by the fact that in a digging working body of a root-and-field harvesting machine containing inclined spherical discs installed in pairs, having ground loops and mounted by axles on the rack, the discs are made with trapezoidal teeth along the periphery. moreover, the front edges of the teeth are bent inward of the spherical disks, and the rear edges are bent outward. FIG. 1 shows a diagram of a digging tool, side view; in fig. 2 is a view A of FIG. one; in fig. 3 - spherical disk, side view; .on FIG. 4 - the same, top view; in fig. 5 is a view B in FIG. 3. Digging the working body of the root-and-harvesting machine contains pairwise mounted inclined spherical disks 1 mounted by means of axles on a rack (not shown). The discs 1 are made with trapezoidal teeth 2 along the periphery, with the front edges 3 of the teeth 2 bent inward of the spherical discs 1, and the rear edges 4 bent outward. The bends of the edges 3 and 4 are made smooth. Digging up of root crops is as follows. The working tool is inserted into the pile. Due to the forward movement of the harvester and the adhesion of the soil to the discs 1, which is provided by the teeth 2 and the rear bent edges 4, which act as pickers, the discs 1 turn on their axes (Figs. 1 and 2), undermining cleaned cuts, crimping undermined mass, and feed it to subsequent working bodies. Due to the fact that the leading edges 3 of the teeth 2 are bent into the inside of the spherical disks 1, they are inserted into the undermined mass and securely hold it, while no loss of root crops occurs. Making the bends of edges 3 and 4 smoothly ensures the work of the discs without sticking and with a self-cleaning effect, therefore no additional energy is required for the insertion of the discs into the soil.
