The utility model discloses a straw returning device, which comprises a mounting rack and a first grass clearing wheel assembly, wherein the first grass clearing wheel assembly comprises a first fixed support, two first grass clearing wheels and two first connecting shafts; one end of the first fixed support is fixedly connected to the mounting rack; the two first grass clearing wheels are arranged on the other end of the first fixed support; the two first grass clearing wheels are arranged at an inclined angle and are not in contact with each other; each first grass clearing wheel is connected to the first fixed support through one first connecting shaft; one end of each connecting shaft is fixedly connected to the first fixed support; the other end of each first connecting shaft is connected to the corresponding first grass clearing wheel; and each first grass clearing wheel rotates around the corresponding first connecting shaft. When the straw returning device treats straws, each first grass clearing wheel can push the straws on the surface of the land to two sides of each first grass clearing wheel, so that a seeding strip used for seeding, which is not covered by the straws, is sorted out, and the ground temperature cannot be affected so as to facilitate seeding. The straws are piled up in a leisure line without burning the straws, so that the soil fertility is also effectively improved.
