The flattened corn cobs press downward on the discharge plate 15 located inside the discharge cylinder 10 to rotate the connecting roller 14, so that the corn cobs are arranged inside the two discharge cylinders 10 respectively, and the two lowest corn cobs fall into the arc-shaped structures at the left and right ends of the bottom plate of the screen plate 11 respectively, and the double-axis motor 2 is started, and the output shafts of the double-axis motor 2 respectively drive the four pulleys 1 5 to rotate, and the four pulleys 1 5 respectively drive the corresponding pulleys 2 6 to rotate through belts, thereby driving the four annular threshing knives 4 to rotate at high speed, and the motor 1 74 is started, and the output shaft of the motor 1 74 drives the roller 72 to rotate at a uniform speed, and the roller 72 drives the T-bar 76 through the spiral groove 73 to push the two push plates 77 to move forward and backward under the restriction of the limit frame 75.
