[0031] Working principle: When the device is used, the rice is fed into the screening drum 65 through the feed pipe 9, and then the motor 61 is turned on, the motor 61 drives the driving rod 64 to rotate, and the rotation of the driving rod 64 drives the screening drum 65 and the rice milling rod 63 to rotate. At this time, the steel particles inside the screening drum 65 and the rice milling rod 63 begin to remove the bran layer on the surface of the rice, and then the discharge door 4 is opened, and the milled rice falls onto the screen 55. Due to the rotation of the driving rod 64, the belt 62 starts to move, and the movement of the belt 62 causes the driven rod 51 to start rotating, and the rotation of the driven rod 51 causes the convex rod 52 to lift the first receiving The first storage box 56 and the screen 55 are connected. At this time, the spring 57 is pulled up, and then as the protruding rod 52 leaves, the spring 57 contracts, driving the screen 55 and the first storage box 56 to descend, thereby achieving the effect of vibrating the screen, and the rice sieved by the vibration falls into the first storage box 56. During the use of the device, the fan in the bellows 1 is turned on, and air is blown into the screen box through the ventilation slots to blow the bran layer attached to the inner wall of the screening box 2 and the screening cylinder 65 into the second storage box 8, thereby avoiding the bran layer from adhering to the rice after rice milling and flowing out with the processed rice, thereby affecting subsequent processing.
