Compartment-transported material leveling device

The invention relates to a compartment-transported material leveling device, comprising a shelf arranged at the upper part of the compartment and a leveling mechanism arranged on the shelf; wherein the leveling mechanism comprises a plain barreled roll and a grooved roller with axial dimension being smaller than the internal width of the compartment, the plain barreled roll is located behind the grooved roll in the advancing direction of the compartment; at least one convex ridge is arranged at the periphery at the outside of a roller of the grooved roll. In the invention, two leveling rolls: the plain barreled roll and the grooved roll for balancing weight are provided, wherein the grooved roll is used for creating grooves on the material and then the plain barreled roll is used for rolling and compressing the material surface with grooves; so that in the process of compression, the material at the two sides of the grooves can be compressed and rolled to the grooves; as a result, damage to the compartment or
