LAND LEVELLER

The present disclosure relates to a land leveler, and relates to the field of engineering machinery to optimize the structure of a swing frame. The land leveler comprises a vehicle frame and a swing frame. The swing frame comprises a supporting beam assembly and connecting parts, wherein the supporting beam assembly comprises multiple beam members, and the multiple beam members are connected sequentially at end parts, such that the multiple beam members form a closed shape. The connecting part is arranged at the connecting end part between two adjacent beam members. At least one connecting part is rotatably connected with the vehicle frame, and at least another connecting part is rotatably connected with a driving part. For the supporting beam of the above structure, under the same bearing capability, the supporting beam assembly with the above structure has a smaller structure, each beam bears weight, and the occupied size is small and the weight is light, thereby being beneficial for performance improvement of the whole vehicle, and beneficial for implementation of lightweight design of the whole vehicle.
