Roadbed milling and leveling device

The invention relates to the field of pavement milling and planing, and particularly discloses a roadbed milling and planing leveling device. The roadbed milling and planing leveling device comprises a shell and a leveling assembly; the pavement leveling plate is arranged at the position, corresponding to the pavement, of the shell. The roadbed leveling plate is arranged at the position, corresponding to the roadbed, of the shell, and rollers are rotationally arranged on the lower side of the roadbed leveling plate. A first rotating wheel is fixedly arranged in the middle of one side of the road surface leveling plate, a second rotating wheel is arranged on one side of the roadbed leveling plate, first limiting blocks are arranged on the two side walls of the road surface leveling plate respectively, first arc-shaped grooves matched with the first limiting blocks are formed in the inner wall of the shell, and first springs matched with the first arc-shaped grooves are arranged on the two sides of the first li
