[0002] Corn starch, also known as maize starch, commonly known as six-grain powder, is a white powder slightly tinged with light yellow. After soaking corn with 0.3% sulfurous acid, it is made through processes such as crushing, sieving, precipitation, drying, and grinding. Ordinary products contain a small amount of fat and protein, etc. Among them, grinding plays an important role in the starch production process and is the key to producing corn starch.

An inlet pipe 32 is fixedly connected to the input end of the collecting box 33. The inlet pipe 32 is fixedly connected to the roller shaft 30. An outlet pipe 34 is fixedly connected to the output end of the collecting box 33. A first feeding port 35 is formed in the feeding bin 26. The first feeding port 35 is fixedly connected through the crushing bin 13. A second feeding port 36 is formed in the feeding bin 26. The second feeding port 36 is located below the feeding bin 26. Two sets of a first transmission gear 5, a first driven gear 6, a support seat 7, a threaded rod 8, and a threaded block 9 are provided. The two sets of the first transmission gear 5, the first driven gear 6, the support seat 7, the threaded rod 8, and the threaded block 9 are evenly distributed on the base 2. The feeding bin 26 is fixedly connected through the grinding bin 29. When using the fine grinding device for producing corn starch, the crushing motor 16 is started. The second driven gear 18 drives the first crushing shaft 20 to rotate. At the same time, the second driven gear 18 drives the third driven gear 19 to rotate. The third driven gear 19 drives the second crushing shaft 21 to rotate. Since the rotation trajectories of the first crushing shaft 20 and the second crushing shaft 21 are opposite, the first crushing shaft 20 and the second crushing shaft 21 break the corn kernels, making it easier to grind the corn starch and achieving a better grinding effect.

[0032] Working principle: Put the corn kernels into the hopper 12, start the lifting motor 3, and the lifting motor 3 drives the transmission shaft 4 to rotate. The transmission shaft 4 drives the first driven gear 6 to rotate, the first driving gear 5 drives the first driven gear 6 to rotate, the first driven gear 6 drives the threaded rod 8 to rotate, and the threaded rod 8 drives the threaded block 9 and the hopper 12 to rise. When the threaded block 9 drives the hopper 12 to rise to a certain height, the incomplete gear 11 meshes with the rack 14 on the crushing chamber 13, and the incomplete gear 11 starts to rotate. The incomplete gear 11 drives the hopper 12 to rotate through the rotating shaft 10. When the incomplete gear 11 contacts the highest point of the rack 14, the hopper 12 starts to turn over, and the corn kernels in the hopper 12 are poured into the crushing chamber 13. At this time, start the crushing motor 16, and the crushing motor 16 drives the second driving gear 17 to rotate. The second driving gear 17 drives the second driven gear 18 to rotate, the second driven gear 18 drives the first crushing shaft 20 to rotate. At the same time, the second driven gear 18 drives the third driven gear 19 to rotate, and the third driven gear 19 drives the second crushing shaft 21 to rotate. Since the rotation trajectories of the first crushing shaft 20 and the second crushing shaft 21 are opposite, the first crushing shaft 20 and the second crushing shaft 21 crush the corn kernels. The crushed corn kernels enter the feeding bin 26 through the first feeding port 35. At the same time, the crushing motor 16 drives the driving pulley 22 to rotate, the driving pulley 22 drives the driven pulley 24 to rotate through the rack 14, and the driven pulley 24 drives the auger shaft 23 to rotate. Due to the rotation of the auger shaft 23, the corn fragments move forward, and the corn fragments fall into the grinding chamber 29 through the second feeding port 36. At the same time, start the grinding motor 28, and the grinding motor 28 drives the roller shaft 30 to rotate. The rotation of the roller shaft 30 generates a centrifugal force that causes the corn kernels to spread around and fall into the gap between the grinding chamber 29 and the roller shaft 30. The roller shaft 30 starts to grind the corn fragments. When the corn kernels are ground into powder, start the collection box 33. The collection box 33 generates a negative pressure, and the collection box 33 sucks the corn starch in the grinding chamber 29 through the feeding pipe 32 by the negative pressure, and then discharges and collects the starch through the discharge pipe 34.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
