The rice mill is powered by a driving motor 2. When the rice mill is in work, the driving motor 2 outputs power and is output to the rice mill spindle 3 through the main transmission belt pulley assembly 6, and the rice mill spindle 3 rotates. While the rice mill main shaft 3 rotates, power is output to the transmission assembly 9 and the fan 11 by the first driven pulley assembly 10 and the second driven pulley assembly 12, respectively. The transmission component 9 drives the three-layer grain sieve 5 and the double-layer vibrating sieve 8 to move. The grain 511 containing impurities is fed into a three-layer grain sieve 5, the grain 511 from which the impurities are sieved enters a rice milling chamber 1 from a feed hopper 4, and the sieved coarse impurities 510 and fine impurities 512 are respectively discharged out of the three-layer grain sieve 5. The grain 511 enters the rice milling chamber 1, and rice milling and husking are realized under the coordination of a rice milling machine spindle 3. In the rice milling process, the fan 11 works to extract the chaff and the bran powder generated in the process. The white rice obtained after milling and husking enters a double-layer vibrating screen 8 through a rice outlet assembly 7, and the double-layer vibrating screen 8 realizes the sorting, crushing and sorting of the white rice.

In this rice mill, rice mill main shaft 3, three-layer millet sieve 5 and double-deck shale shaker 8 need reduce driving motor 2 rotational speed, therefore the driving wheel 601 diameter of main drive belt pulley subassembly 6 and the driven driving pulley subassembly 12 of second all is less than from driving wheel 602 diameter to reach the effect of speed reduction. The fan 11 needs to increase the rotation speed of the driving motor 2, so the diameter of the driving wheel 601 of the second driven transmission belt pulley component 12 is larger than that of the driven wheel 602 to achieve the effect of increasing the speed.

The coarse impurity screen 502 of the three-layer grain screen 5 has a mesh opening size through which most of the grains 511 and the fine impurities 512 pass. The grain sieve 504 has a mesh aperture set to a size that blocks the grains 511 and allows the fine impurities 512 to pass through. When the three-layer grain sieve is in operation, grains 511 containing impurities are fed into the sieve frame 501, and the three-layer grain sieve 5 operates under the driving of the power of the rice mill. The grains 511 containing impurities fall onto the coarse impurity screen 502, the coarse impurity screen 502 has screen holes through which the grains 511 and the fine impurities 512 pass, and the coarse impurities 510 which cannot pass are discharged from the coarse impurity discharge port 503 by the vibration of the three-layer grain screen 5. The grain 511 containing the fine impurities 512 falls onto the grain sieve 504, and since the mesh aperture of the grain sieve 504 is set to a mesh aperture capable of blocking the grain 511 and allowing the fine impurities 512 to pass through, the fine impurities 512 fall onto the fine impurity baffle 507 through the mesh aperture of the grain sieve 504, and are discharged from the fine impurity discharge port 508. The grains which do not pass through the grain sieve 504 are discharged from the grain 511 discharging port 506 by the vibration of the three-layer grain sieve 5.

In order to achieve a better screening effect, the outer side of the coarse impurity screen 502 is hermetically connected with the inner side wall of the screen frame 501. The higher end of the grain sieve 504 and the two side surfaces adjacent to the higher end are hermetically connected with the inner side wall of the sieve frame 501. The fine impurity baffle 507 and the two side faces adjacent to the higher end thereof are hermetically connected with the inner side wall of the screen frame 501.

The actuating lever 904 of the present actuating assembly 9 includes a straight lever and a curved lever; when the transmission shaft is a straight lever, the eccentric shaft body of the secondary reduction transmission shaft 901 is divided into two sections, and is connected with a connecting rod 903 through an eccentric bearing 906 arranged in the middle of a first eccentric shaft body 9011, and is connected with the straight lever through the connecting rod 903; when the secondary speed reduction transmission shaft 901 is a bending lever, the eccentric shaft bodies of the secondary speed reduction transmission shaft 901 are three-section, are connected with the connecting rod 903 through the third eccentric shaft body 9013, and are connected with the bending lever through the connecting rod 903. In both lever modes, the second eccentric shaft 9012 of the secondary reduction transmission shaft 901 rotates to drive the contact bearing 908 to rotate, so as to contact with the vibrating screen connecting plate 902 and drive the vibrating screen connecting plate 902 to move horizontally. When the double-layer vibrating screen is operated, the secondary speed reduction transmission shaft 901 is in butt joint with power of the rice mill, the secondary speed reduction transmission shaft 901 is driven to rotate through the power, the second eccentric shaft body 9012 drives the contact bearing 908 to translate and to be in contact with the vibrating screen connecting plate 902, and therefore the vibrating screen connecting plate 902 is driven to translate, the double-layer vibrating screen 8 is operated, and the rice sorting and crushing functions are achieved. When the transmission lever 904 is a straight lever or a bent lever, the rotation of the secondary speed reduction transmission shaft 901 drives the eccentric bearing 906 and the third eccentric shaft body 9013 to rotate respectively, so that the connecting rod 903 is driven to move forwards and backwards, the transmission lever 904 is driven to move around the pivot of the connecting rod 903, and the three layers of grain sieves 5 connected with the transmission lever 904 reciprocate forwards and backwards along with the transmission lever 904, so that the vibration screening function is realized. The lever fulcrum assembly 905 is connected with the rice mill through a fulcrum fixing back plate 9054, and the position of the lever fulcrum assembly is determined according to actual transmission conditions.
