A novel drum-type arc-shaped cutting device comprises a drum-type cutter, a curved bar, a driving belt wheel and a driven belt wheel. The drum-type cutter is a hollow cylinder, a plurality of mounting grooves are obliquely and evenly formed in the side face of the drum-type cutter, a plurality of mounting bases are arranged in each mounting groove, and an arc-shaped blade is mounted through each mounting base. The curved bar is provided with a driving shaft which penetrates through middle holes in two bottom faces of the drum-type cutter, a driving gear is mounted at the tail end of the driving shaft and engaged with a driven gear, and a gear shaft on the driven gear is in transmission connection with a belt wheel shaft on the driving belt wheel through a shaft belt. The driving belt wheel and the driven belt wheel are in transmission connection through a conveying belt which is located under the drum-type cutter. The novel drum-type arc-shaped cutting device can conduct food cutting work rapidly and efficiently, and is simple, convenient to use, easy to operate, capable of saving time and labor, safe, reliable, high in practicality and convenient to popularize.
