Our traditional corn threshing machine, threshing operations are mainly done by stirring and impact of the the coronavirus plate installed in the high-speed rotation of the spindle teeth right ear of corn, this threshing mechanical damage to the ear of corn, broken ratehigh. Therefore, the design ofa new, inexpensive, low breakage rate of the corn sheller, corn production has a very important practical significance. In order to adapt to the need to require a small amount of corn threshing, and avoid using artificial means ofa small amount of corn threshing, reduce the labor intensity of the farmers in the corn threshing, improve work efficiency, and design one for individuals, families, small artificial corn sheller. This small artificial corn feeding device, the threshing device, separating the cleaning device, the discharge port, rack and gear. Human, the machine power source through two gear sprockets delivered to the nail tooth threshing drum, nail tooth threshing cylinder with the hole gravure corn threshing, leave out the corn kernels from the sieve holes slip by the decline in board outside the body, the corn cob from the body outside of the discharge port.
