The second grinding disc 201 is provided on the gear ring 5 by welding. There is a gap between the second grinding disc 201 and the first grinding disc 2. The gear 4 meshes with the gear ring 5. The storage bin 6 is provided on the second grinding disc 201 by welding. The feeding pipe 601 is connected and communicated with the storage bin 6. The feeding pipe 601 is aligned with the notch on the second grinding disc 201, and can accurately feed rice into the second grinding disc 201. It further includes a sieve mesh 7. The sieve mesh 7 for screening rice is embedded inside the storage bin 6.

[0025] Referring to Figure 1 as shown, it further includes a glass cover plate 17. The glass cover plate 17 for viewing the situation is embedded on the storage bin 6.

[0026] Referring to Figure 1As shown, it further includes a material receiving frame 18. The support frame 1 is provided with a material receiving frame 18 for collecting rice noodles by welding. The material receiving frame 18 has a relatively large volume and can better catch the rice noodles.

[0027] When grinding rice into powder, the user pours an appropriate amount of rice into the storage box 6. The sieve 7 screens the rice, so that the stones in the rice stay on the sieve 7, thus avoiding the reduction of the grinding purity due to the admixture of stones in the rice. The screened rice falls into the storage box 6 and enters the second grinding disc 201 through the feed pipe 601, and then falls on the first grinding disc 2. The user turns on the motor 3. The output shaft of the motor 3 rotates to drive the gear 4 to rotate and mesh with the gear ring 5. Then, the gear ring 5 drives the second grinding disc 201 to rotate and cooperate with the first grinding disc 2 to grind the rice into rice noodles. The rice noodles overflow on the outer ring of the first grinding disc 2 through the gap between the second grinding disc 201 and the first grinding disc 2. The user uses a brush to sweep the rice noodles off the first grinding disc 2. The material receiving frame 18 collects the swept rice noodles to prevent the rice noodles from falling on the ground. During the grinding process, the user checks the height of the rice in the storage box 6 through the glass cover plate 17, so as to facilitate timely feeding. When the rice grinding is completed, the user turns off the motor 3. Embodiment 2

[0028] On the basis of Embodiment 1, referring to Figure 1 and Figure 3 As shown, it further includes a fixing block 8 and a row brush 9. The gear ring 5 is provided with a fixing block 8 by welding. The fixing block 8 is embedded with a row brush 9 for brushing off the rice noodles. The row brush 9 can be in full contact with the outer ring of the first grinding disc 2, which is convenient for sweeping off the rice noodles.

[0029] When the gear ring 5 rotates, the gear ring 5 drives the fixing block 8 to rotate, and then drives the row brush 9 to rotate to brush off the rice noodles on the outer ring of the first grinding disc 2, thus replacing the user to manually brush the powder with a brush and achieving the purpose of automatic powder brushing.

[0030] Referring to Figure 4 As shown, it further includes a cover plate 10, a clamping block 11, a torsion spring 12 and a lever 1201. The second grinding disc 201 is rotatably provided with a cover plate 10. The cover plate 10 is in contact with the feed pipe 601. The cover plate 10 is provided with a clamping block 11 by welding. A torsion spring 12 for auxiliary reset is sleeved on the second grinding disc 201. The two ends of the torsion spring 12 are respectively connected to the cover plate 10 and the second grinding disc 201. The gear 4 is provided with a lever 1201 by welding. The lever 1201 can hit the clamping block 11.

[0031] When the motor 3 is started to drive the gear 4 to rotate, the gear 4 drives the lever 1201 to rotate and hit the latch 11, driving the cover plate 10 to rotate and open the blanking pipe 601. The torsion spring 12 deforms. The gear 4 continues to drive the lever 1201 to rotate and separate from the latch 11. The torsion spring 12 returns to its original state, causing the cover plate 10 to drive the latch 11 to reverse and reset. The gear 4 continuously drives the lever 1201 to rotate, causing the lever 1201 to intermittently hit the latch 11 and drive the cover plate 10 to rotate and open the blanking pipe 601, thereby achieving the purpose of quantitative blanking and facilitating the successive feeding of an appropriate amount of rice into the second grinding disc 201 for grinding into powder.

[0032] Referring to Figure 1 and Figure 5 As shown, it further includes a shifting block 13, a sieving frame 14, a fixing frame 1501, a guiding rod 15 and an elastic member 16. The shifting block 13 is slidably arranged on the first grinding disc 2. The sieving frame 14 for sieving the rice flour is arranged on the shifting block 13 by welding, which can make the rice flour more delicate. Two fixing frames 1501 are arranged on the first grinding disc 2 by welding. The two fixing frames 1501 are symmetric left and right. The guiding rod 15 is arranged on the fixing frame 1501 by welding. The sieving frame 14 slides between the two guiding rods 15. The elastic member 16 is sleeved on the guiding rod 15, and both ends of the elastic member 16 are respectively connected to the sieving frame 14 and the fixing frame 1501.

[0033] When brushing the rice flour on the outer circle of the first grinding disc 2, the rice flour falls into the sieving frame 14. The row brush 9 intermittently presses the sieving frame 14 to move leftward during rotation, and the elastic member 16 deforms. Furthermore, the sieving frame 14 sieves the rice flour to prevent the rice flour from caking when it falls on the material receiving frame 18. When the rice grinding is completed, the user turns off the motor 3 to stop the row brush 9 from pressing the sieving frame 14, and the elastic member 16 returns to its original state to make the sieving frame 14 move rightward and reset.
