The utility model relates to the mechanical technique field of agricultural products processing, especially a novel automatic cutter with simple structure and convenient use. Compared with prior art, the unloading device of the novel automatic cutter is arranged above the conveyer which comprises a chain and a conveyer belt. The unloading device consists of a funnel and a roller. The roller contacts with the conveyer belt, and the funnel is arranged at the overhead position of the roller, and the unloading opening of the funnel is directed at the roller. Vegetables piled up disorderly in the funnel is discharged from the unloading opening to the roller, and as the plastic films of the roller contact with the dentate plastic housing of the conveyer, the vegetables between two plastic films are sent to the deep groove in the dentate plastic housing. The utility model is advantageous in that as the width of the deep groove is smaller than the length of vegetables and under the pressing of plastic films, vegetables can not exceed the outboard of the deep groove, thereby vegetables can only be transversely placed in the deep groove, and the ordered arrangement of vegetables is achieved, vegetables are evenly cut in a right-angle shape, cutting efficiency is improved and good market prospect is achieved.
