[0002] A split wheel hub is a wheel hub structure composed of multiple independent parts, usually including an inner ring, an outer ring and a central structure. Compared with the traditional one-piece wheel hub, the split wheel hub is more flexible in design and manufacturing. It can be combined with various parts by bolts, welding, interference fit and other methods. The application of split wheel hub in agricultural machinery, especially seed drills, has significant advantages, including convenient maintenance, flexible design, light weight, high durability, and better shock absorption and control performance. These advantages not only help to improve the efficiency and service life of the seed drill, but also reduce maintenance costs and improve the overall economic benefits of agricultural production.
[0003] However, after the inner ring and outer ring of the split wheel hub are fixedly connected with bolts, since the seeder works in the fields, a large amount of soil is easily adhered to the bolts, and more pesticides are used during farming. The chemical components in the pesticides enter the soil and wrap around the bolts, causing a certain degree of rust on the bolts, which makes it inconvenient to disassemble the bolts connecting the inner ring and the outer ring. Therefore, a split wheel hub jacket is needed to solve the above problem. Utility Model Content
