Carriage transportation material leveling device

The utility model relates to a carriage transportation material leveling device, which comprises a frame body arranged above a carriage and a leveling mechanism arranged on the frame body; wherein the leveling mechanism comprises a flat roll and a grooved roll; the axial sizes of the flat roll and the grooved roll are less than the inner width of the carriage; and the flat roll is arranged behind the grooved roll at the traveling direction of the carriage; wherein at least a convex ridge is arranged on the outer circumference of the drum of the grooved roll. As two leveling drums of the flat roll and the grooved roll with the counterweight are arranged on the leveling device, grooves are arranged above the material through the grooved roll, and the material surface with grooves are compacted through the flat roll in a rolling way; in the compaction process, the materials at both sides of the groove can be pressed and roll in the groove, therefore the damage to the carriage and the drum can be avoided owing to
