[0002] Agricultural machinery refers to mechanical equipment specially used for agricultural production. They can replace or assist manual labor and improve agricultural production efficiency and quality. The agricultural machinery hub refers to the core part of the wheel installed on agricultural machinery (such as tractors, harvesters, etc.). It not only supports and connects the wheel to the vehicle's transmission system, but also bears the weight and torque of the entire vehicle.

[0003] Because the use environment of agricultural machinery is relatively complex, the wheels on the agricultural machinery are easily damaged. In order to allow the agricultural machinery to be used normally, the damaged tires on the wheels need to be replaced. However, in the existing wheel hubs, if the tires need to be replaced, a special tire changer is required. In this case, the tires need to be replaced at a maintenance organization, which can easily reduce the use efficiency of the agricultural machinery. Utility Model Content
