The outer wall is in contact with the outer walls of the two baffles 3. The shaft of the feed roller 4 and the shaft of one of the gears 8 are respectively fixedly connected to the first pulleys 9.

[0030] In the technical solution of this utility model, the rotation of gear 8 can drive the rice milling mechanism to rotate, and gear 8 drives the feed roller 4 to rotate under the cooperation of the first pulley 9 and the first belt 10. When the feed roller 4 rotates, the gap between the feed hole 5 and the two baffles 3 makes it convenient to adjust the falling frequency of the rice, so that the rice milling mechanism can better perform the function of milling rice.
[0031] In addition, the housing 1 can provide rotational support for the rice milling roller 15, which in turn can mill rice.
[0032] In the technical solution of this utility model, such as Figure 3 As shown, two inclined plates 16 are fixedly connected to the inner wall of the box 1 located on both sides of the two rice milling rollers 15. The two inclined plates 16 are in contact with the outer wall of the rice milling rollers 15. Two central conveying holes 17 are opened on the outer wall of the box 1. The central conveying holes 17 correspond to the lower end of the inclined plates 16. The inclined plates 16 can collect the scattered rice grains, and the unmilled rice grains can be discharged and collected by the central conveying holes 17.
[0033] In the technical solution of this utility model, such as Figure 3 As shown, an installation plate 18 is installed on the inner wall of the box 1 located below one of the rice milling rollers 15.

[0034] In the technical solution of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, a discharge hole 22 is provided on the outer wall of the box 1 located below the rice milling roller 15. A sieve plate 20 is rotatably installed on the inner wall of the box 1 inside the discharge hole 22. An eccentric roller 21 is rotatably installed on the inner wall of the box 1. The outer wall of the eccentric roller 21 contacts the outer wall of the sieve plate 20 on the side away from the discharge hole 22. The sieve plate 20 is inclined. When the eccentric roller rotates, it can drive the sieve plate 20 to vibrate, thereby facilitating the sieve plate 20 to remove the chaff from the rice, and then allowing the rice to be discharged from the discharge hole 22. The shaft of another gear 8 is connected to the eccentric roller 21. The roller 21 has a shaft fixedly connected to a second pulley 13.

[0036] In use, the motor 11 first drives the two gears 8 to rotate. The two gears 8, in conjunction with the first belt 10 and the second belt 14, drive the first pulley 9 and the second pulley 13 to rotate. Then, as the feed roller 4 rotates, the gap between the feed hole 5 and the two baffles 3 allows for easy control of the rice's falling frequency, thus facilitating better rice milling by the rice milling roller 15. Furthermore, the slightly different number and shape of the teeth on the two gears 8 result in a slight difference in the rotational speed of the two rice milling rollers 15. It can better mill rice, while the inclined plate 16 can collect scattered rice. Unmilled rice can be discharged and collected through the central conveying hole 17. After milling, the rice can be initially separated from the bran with the help of the blower 19. When the eccentric wheel drives the screen plate 20 to shake, the rice bran falls between the inner wall of the box 1 and the screen plate 20. The screen plate 20 can then screen the rice for bran a second time, achieving efficient bran screening. The rice can be discharged through the discharge hole 22, and the rice bran can be discharged through the discharge pipe 24.
