With the continuous improvement of rice varieties, especially organic rice, the output of slender grain rice has been increasing in recent years. This kind of rice will produce a large number of cracking phenomena due to its own reasons during the harvesting and threshing process. Traditional rice mills will increase the broken rice rate due to backward technology.

[0022] See also Figures 1 to 4In the embodiment of the present invention, a new rice milling device suitable for fine processing of organic rice includes a machine body 1, a feed port 2, and a grinding wheel A8, a grinding wheel B10, and a grinding wheel C11. A feed plate 6 and a distributor 7 are provided in the feed port 2. The distributor 7 controls the unloading of the material. The feed plate 6 transports the rice. The feed plate 9 guides the rice into the space between the grinding wheels A8 and B10. The machine body 1 is provided with rotatable grinding wheels A8, B10, and C11. The grinding wheels A8, B10, and C11 are driven by a chain transmission. The top of the machine body 1 is provided with a feed port 2, and the interior of the machine body 1 is provided with an air blowing pipe 12, which is located at the unloading position of the grinding wheel A8 and the grinding wheel B10, and the air blowing pipe 12 is provided with a blowing guide plate 13. The top of the machine body 1 is provided with a dust collecting box 18 which can suck out the impurities after being blown up. The machine body 1 is provided with a receiving plate 14 for receiving the fallen rice, which sends the rice between the grinding wheel B10 and the grinding wheel C11 for the second grinding, and finally sends it out through the discharge port 5. The adjustment of the grinding wheel A8, the grinding wheel B10 and the grinding wheel C11 and the rice milling and peeling are carried out. The principle is the existing technology and will not be described in detail here. The chain transmission and driving equipment all adopt the existing technology of the existing rice milling device. The present application is equipped with an air blowing pipe 12. The air source of the air blowing pipe 12 comes from the compressor. The air pressure generated by the compressor is input into the air blowing pipe 12. The air blowing pipe 12 is provided with a plurality of air nozzles arranged in a line. The air flow is ejected through the air nozzles to blow up the rice and impurities that have been peeled and milled once. As the air flow travels longer, the air flow speed weakens, the rice and impurities carried have different gravity, and the travel distances carried by the air flow are also different, and the rice will fall prematurely. , and impurities will be carried a longer distance by the airflow and approach the dust box 18. The dust box 18 is driven by the fan to generate suction, and the airflow and the impurities carried in the airflow are sucked in and discharged together. The role of the air blowing pipe 12 in this application is not only to blow up the rice and impurities, but also to separate the rice and impurities by the difference in gravity under the action of the airflow, and to blow the rice and impurities in the air to make them better separated, thereby improving the fluidity of the airflow, rice and impurities in the rice milling room, thereby improving the separation effect.
[0023] In a preferred embodiment, a material separation baffle 15 is provided inside the body 1, and the material separation baffle 15 is vertically arranged. One side of the material separation baffle 15 is connected to a vibrating screen 16, and a vibrating motor 17 is provided at the bottom of the vibrating screen 16. The vibrating screen 16 is connected to the receiving plate 14 through a vibrating spring. No matter how the airflow is adjusted, the rice and impurities still cannot be completely and effectively separated by the airflow. Some rice will still be mixed in the airflow. Under the action of the material separation baffle 15, most of the rice will be separated on the left, and impurities and some The rice is blown to the right side of the material-dividing baffle 15, and some lighter impurities or dust will be sucked into the dust collection box 18, while some impurities and rice will fall on the vibrating screen 16 on the right side of the material-dividing baffle 15. Under the action of the vibration motor 17, the vibrating screen 16 is vibrated, so that the rice on the vibrating screen 16 passes through the sieve holes of the vibrating screen 16 and falls onto the receiving plate 14. The rice on both sides of the material-dividing baffle 15 is reunited through the receiving plate 14 and sent to the grinding wheels B10 and C11 for further rice milling to reduce the loss of rice.
[0024] In a preferred embodiment, the vibrating screen 16 is provided with an impurity discharge end 3 on the side away from the material dividing baffle 15, and a miscellaneous material slide plate is provided in the impurity discharge end 3. One end of the miscellaneous material slide plate is fixed to the material receiving plate 14, and the other end extends to the outside of the machine body 1. The impurities separated by the vibration of the vibrating screen 16 fall from the vibrating screen 16 onto the miscellaneous material slide plate and are discharged. Under the rotation of the vibration motor 17, the vibrating screen 16 separates the top rice and impurities, and the rice falls into the material receiving plate 14 by vibration. The impurities are transported from the vibrating screen 16 to the impurity discharge end 3 under the action of vibration and slide out from the miscellaneous material slide plate.
[0025] In a preferred embodiment, the receiving plate 14 is a screen, and the rice blocked by the material dividing baffle 15 and separated by the vibrating screen 16 will fall onto the receiving plate 14. The sieve holes on the receiving plate 14 filter the broken rice. The receiving plate 14 has a certain inclination angle. After the rice falls on the receiving plate 14, it slides down between the grinding wheel B10 and the grinding wheel C11, and there is a distance between the two. This distance will screen the rice and screen out the broken rice.
[0026] In a preferred embodiment, a granulator is provided in the discharge port 5, and the rice after being crushed by the grinding wheel B10 and the grinding wheel C11 falls on the granulator. The granulator is composed of a plurality of granulation plates 19 and a plurality of connecting plates 20. Two adjacent granulation plates 19 are connected by the connecting plate 20. The rice grains also need to be subjected to secondary finishing rolling to further remove the coarse rice skin in the brown rice. The secondary finishing rolling will also cause a certain amount of broken rice, which is further screened by the granulator so that the rice skin powder and broken rice are sent into the broken rice and rice skin slot 4 for delivery.
[0027] In a preferred embodiment, the top surface of the particle board 19 is provided with a bevel a, a bevel b, a bevel c and a bevel d. The top of the particle board 19 is the bevel a, which determines the height difference between the left and right sides of the particle board 19. The top surface of the particle board 19 is two bevels b, so that the top surface of the particle board 19 is Λ-shaped. The top of the particle board 19 is provided with a stepped bevel c and a bevel d. The inclination angle of the bevel d is greater than the inclination angle of the bevel c, and the bevel d and the bevel c are both less than the horizontal angle. The structure can make the rice grains roll and fall on the beveled surface a of the particle separation plate 19, and the beveled surface b makes the rice grains centered between the two particle separation plates 19. Broken rice will fall from the gap between them to the broken rice and rice skin groove 4 due to insufficient particle size, while the rice grains with complete particle size will roll or slide to the end and be sent out under the action of the inclination of the beveled surface a and the beveled surface b. The beveled surface c and the beveled surface d will adjust the direction of the rice grains and separate the rice grains. Compared with the screening effect of the screen, it is better and will not cause the sieve holes to be blocked.
[0028] In a preferred embodiment, the top of the connecting plate 20 is a beveled surface, and the height of the left side of the beveled surface is greater than the height of the right side of the beveled surface. Broken rice and rice bran powder may fall, and under the action of the beveled surface of the connecting plate 20, the broken rice and rice bran powder are guided toward the broken rice and rice bran notch 4 to achieve final separation, so that the impurity content of the processed rice grains is very low, reducing the subsequent separate separation process.
[0029] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For any details not described in individual embodiments, reference may be made to the description in other embodiments.
