摘要：
The utility model relates to agricultural machinery, in particular, to soil-cultivating working bodies intended for combing weeds and leveling the field surface with simultaneous compaction of the soil at a predetermined depth. During the operation of the ring roller, dust gets into the gaps between the hub of the ring working body and the axis of the roller, it is pressed to a solid state and the roller cannot be disassembled without soaking the dust in water. The task of the utility model is to reduce the complexity of the repair of the roller with ring working bodies by changing the design of the hub with the ability to quickly disassemble the ring roller. The annular working body includes a hub with through oblong holes, on which with the help of the spokes a tapered ring is made, made of a rectangular strip. The ring working body is mounted on the axis of the ring roller and is connected to other working bodies with the help of projections on the hub. Skating rinks with ring tools may be, for example, a ring harrow or be part of a soil cultivating or combined sowing tools and aggregates, etc. This is achieved by the fact that in the central part of the hub housing there are at least two oblong holes that reduce the amount of dust pressed in the gap between the axle and the hub and ensure its wetting with water. As a result, the compressed dust softens to a gel state, and the annular working bodies are easily removed from the shaft. In addition, when casting the hub into a mold with an orifice casting pattern, the metal intensity of the hub is reduced by 30%.Полезная модель относится к сельскохозяйственному машиностроению, в частности к почвообрабатывающим рабочим органам, предназначенным для вычесывания сорняков и выравнивания поверхности поля с одновременным уплотнением почвы на заданной глубине. При работе кольцевого катка в зазоры между ступицей кольцевого рабочего органа и осью катка попадает пыль, ее спрессовывают до твердого состояния и каток невозможно р
