Rotary gear ring structure and land leveler

The invention discloses a rotary gear ring structure and a land leveler and relates to the field of engineering machinery. The rotary gear ring structure is used for optimizing the structure of an existing rotary gear ring structure. The rotary gear ring structure comprises a gear panel, a rotary ring and a connecting structure. The gear panel and the rotary ring are detachably connected, and the connecting structure and the rotary ring are fixedly connected. According to the technical scheme, the gear panel and the rotary ring are detachably connected. During practical use, the gear panel can be abraded and damaged, when the gear panel needs to be replaced, the gear panel can be detached from the rotary ring, then only the gear panel is replaced, and it is not needed to replace the whole rotary gear ring structure. Thus, the replacement cost can be reduced, materials and resources are saved, and the gear panel is easier to replace and assemble.
