[0002] As one of the main grains, rice is essential in people's lives. Rice is produced from paddy through multiple processes. During the production process, the operation of rice milling is essential. Through the action of rice milling, the outer coarse fiber and bran powder are removed, making it into smooth and edible white rice.

[0003] Currently, in the market, rice milling of paddy is mainly carried out by a rice milling machine. This process not only improves the appearance of rice but also enhances its taste. In the prior art, during the rice milling operation, paddy is conveyed into the interior of the rice milling machine through the action of a conveyor, and corresponding operations are performed on the paddy by the rice milling machine. However, the plumpness of paddy varies. During the operation of the rice milling machine on paddy, some paddy with smaller particle sizes cannot be husked and are directly discharged together with the rice husks, resulting in waste of food.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-13, the present invention provides a technical solution: a multi-stage intelligent rice mill, which includes a housing 1, a screening component 7, a feeding component 11 and an adjusting component 12. Three rice milling bins 2 are installed inside the housing 1. An outlet pipe 3 is provided on the rice milling bin 2, and a top cover 4 is fixedly connected to the top end of the housing 1. A feeding pipe 5 is provided on the top cover 4, and a feeding hopper 6 is connected to the end of the feeding pipe 5; the screening component 7 is installed inside the housing 1. The screening component 7 includes a first screen 8, a second screen 9 and a third screen 10 installed inside the housing 1, and are respectively installed at the top positions of the three rice milling bins 2. The first screen 8, the second screen 9 and the third screen 10 are mutually attached and inclined, and the pore sizes in the first screen 8, the second screen 9 and the third screen 10 gradually increase. The screening component 7 screens and classifies paddy through the functions of the first screen 8, the second screen 9 and the third screen 10, so that the classified paddy falls into the three rice milling bins 2 respectively for rice milling; the feeding component 11 is arranged in cooperation with the screening component 7, and the feeding component 11 is used to evenly spread the paddy input into the housing 1 through the feeding pipe 5 on the first screen 8; the adjusting component 12 is installed inside the housing 1 and connected to the feeding pipe 5. The adjusting component 12 is used to adjust the feeding speed of paddy, which is convenient for classifying paddy with different particle sizes, and the functions of the feeding component 11 and the adjusting component 12 can improve the rice milling efficiency.

[0032] In this solution, during rice milling, the feeding hopper 6, the feeding pipe 5 and the feeding component 11 evenly transport the paddy to the first screen 8. Since the first screen 8, the second screen 9 and the third screen 10 are connected to each other and are inclined, the paddy will fall from the first screen 8 to the third screen 10. During this process, since the pore sizes of the first screen 8, the second screen 9 and the third screen 10 gradually increase, the paddy is classified through different pore sizes, so that paddy with different particle sizes enters the three rice milling bins 2 respectively for rice milling. During this process, through the function of the feeding component 11, the paddy can be evenly spread on the first screen 8, the second screen 9 and the third screen 10, and through the function of the screening component 7, the first screen 8, the second screen 9 and the third screen 10 can shake and discharge materials, making it easier for the paddy to enter the rice milling bin 2.

[0033] The screening assembly 7 includes a baffle 14 fixed to the bottom ends of the first screen 8, the second screen 9, and the third screen 10. The baffle 14 is slidably connected to the rice milling bin 2. Side baffles 13 fixedly connected to the housing 1 are installed on both sides of the first screen 8, the second screen 9, and the third screen 10. A connecting piece 15 is fixedly connected to the top end of the first screen 8. A fixing frame 16 is fixedly connected to the top end of the connecting piece 15. A connecting frame 17 is fixedly connected to the fixing frame 16. A roller 18 is rotatably connected to the connecting frame 17. A cam 19 is installed on the outside of the roller 18. A driving member 20 connected to the housing 1 is installed on the cam 19. Elastic members 21 are installed on both sides of the bottom end of the baffle 14, facilitating the classification of paddy with different granularities. The driving member 20 includes a support frame 22 fixed to the housing 1. A motor 23 is fixedly connected to the support frame 22. A coupling 24 is fixedly connected to the output end of the motor 23. A driving shaft 25 fixedly connected to the cam 19 is fixedly connected to the end of the coupling 24. The driving shaft 25 passes through the fixing frame 16 and is slidably connected to the fixing frame 16. A chute 26 adapted to the driving shaft 25 is provided on the fixing frame 16, facilitating the provision of stable power. The elastic member 21 includes a fixing seat 27 fixedly connected to the housing 1. A sliding column 28 is slidably connected to the fixing seat 27. A connecting block 29 fixedly connected to the baffle 14 is fixedly connected to the top end of the sliding column 28. A first tension spring 30 fixedly connected to the fixing seat 27 is fixedly connected to the bottom end of the connecting block 29, facilitating the up-and-down vibration of the first screen 8, the second screen 9, and the third screen 10, and accelerating the entry of paddy into the rice milling bin 2.

[0034] In this solution, when milling paddy, after the paddy enters the top of the first sieve 8 through the feeding component 11, by starting the motor 23, the motor 23 will drive the drive shaft 25 to rotate through the coupling 24. The rotation of the drive shaft 25 drives the cam 19 to rotate. The rotation of the cam 19 causes the roller 18 to move up and down. When the cam 19 rotates close to the roller 18 and squeezes it, the roller 18 will move upward. When the roller 18 moves upward, it will pull the first sieve 8 upward through the fixing frame 16. The first sieve 8, the second sieve 9, and the third sieve 10 are connected to each other, so that the second sieve 8 and the third sieve 10 will move upward accordingly. When the first sieve 8, the second sieve 9, and the third sieve 10 move upward, they will drive the connecting block 29 to move upward. Through the action of the connecting block 29, the sliding column 28 moves upward. Through the action of the sliding column 28, the tension spring is stretched. When the cam 19 moves away from the roller 18, the roller 18 will reset due to the action of the tension spring and gravity. Thus, the rotation of the cam 19 causes the first sieve 8, the second sieve 9, and the third sieve 10 to vibrate up and down, which facilitates the paddy to enter the three groups of rice milling bins 2 respectively through the first sieve 8, the second sieve 9, and the third sieve 10.

[0035] In this solution, the baffle 14 and the side baffle 13 enable the paddy to accurately enter the three groups of rice milling bins 2 without spilling out and causing waste.

[0036] In this solution, the chute 26 is provided to facilitate the relative sliding between the fixing frame 16 and the drive shaft 25.

[0037] The feeding component 11 includes a feeding hopper 31 installed at the bottom end of the feeding pipe 5. The feeding hopper 31 is inclined. Both sides of the feeding hopper 31 are fixedly connected with sliding rods 32 that are slidably connected to the top cover 4. The bottom end of the feeding hopper 31 is fixedly connected with a connecting column 33. A swinging member 34 for driving the feeding hopper 31 to swing left and right is fixedly connected to the connecting column 33 to facilitate uniform feeding. The swinging member 34 includes an incomplete gear 36 fixedly connected to the drive shaft 25. A first rack 35 fixedly connected to the connecting column 33 is engaged with the outside of the incomplete gear 36. Both ends of the first rack 35 are fixedly connected with connecting plates 38. A second rack 37 engaged with the incomplete gear 36 is fixedly connected between the two connecting plates 38. And a connecting rod 39 slidably connected to the top cover 4 is fixedly connected to the connecting plate 38 to facilitate driving the feeding hopper 31 to swing.

[0038] In this solution, when the drive shaft 25 rotates, it will drive the incomplete gear 36 to rotate. Through the rotation of the incomplete gear 36, the first rack 35 and the second rack 37 engaged with it will be driven to move. When the incomplete gear 36 meshes with the first rack 35, it will drive the first rack 35 to move towards the side of the housing 1. Therefore, through the action of the connecting column 33 and the connecting plate 38, the hopper 31 and the second rack 37 will be driven to move. However, when the incomplete gear 36 meshes with the second rack 37, it will drive the second rack 37 to move in the opposite direction. At this time, through the action of the connecting plate 38 and the connecting column 33, the hopper 31 will move in the reverse direction. Therefore, when the incomplete gear 36 meshes with the first rack 35 and the second rack 37 respectively, the hopper 31 moves in opposite directions twice, so that the hopper 31 swings left and right, and evenly spreads the paddy on the first screen 8.

[0039] The adjusting assembly 12 includes a sealing plate 40 slidably connected to the feed pipe 5. One end of the sealing plate 40 is fixedly connected to a third rack 41 slidably connected to the top cover 4. The outside of the third rack 41 is engaged with a spur gear 42. The outside of the spur gear 42 is engaged with a fourth rack 44. And the axis of the spur gear 42 is fixedly connected to a rotating shaft 43 rotatably connected to the top cover 4. The end of the fourth rack 44 is connected to a moving member 45 for driving the fourth rack 44 to move, and the feeding speed of the paddy is adjusted by the movement of the sealing plate 40; the moving member 45 includes a moving plate 46 installed inside the housing 1. The moving plate 46 is installed at the top of the third screen 10. And two moving columns 47 slidably connected to the housing 1 are fixedly connected to the moving plate 46. A second tension spring 48 fixedly connected to the housing 1 is fixedly connected to the moving column 47. And a pulling rod 49 slidably connected to the housing 1 and the top cover 4 is also fixedly connected to the moving plate 46. The end of the pulling rod 49 is connected to a delaying member 50. A fixing rod 51 fixedly connected to the fourth rack 44 is connected to the delaying member 50. A support seat 52 fixedly connected to the top cover 4 is slidably connected to the outer side surface of the fixing rod 51, which is convenient for driving the fourth rack 44 to move, and further makes the sealing plate 40 move; the delaying member 50 includes a limiting piece 53 fixedly connected to the fixing rod 51. A sleeve 54 is sleeved on the outer side surface of the limiting piece 53. A pulling piece 55 that is press-fitted with the limiting piece 53 is fixedly connected to the end of the sleeve 54. Through the setting of the delaying member 50, the size of the feed port can be adjusted after the paddy accumulates to a certain extent.

[0040] In this solution, after the paddy enters the inside of the outer shell 1, due to the inclination of the first sieve 8, the second sieve 9 and the third sieve 10, the paddy will gradually accumulate at the top of the third sieve 10. During the accumulation process, the moving plate 46 will move due to the gravity of the paddy. The movement of the moving plate 46 will cause the moving column 47 and the pulling rod 49 to move. The movement of the moving column 47 will stretch the second tension spring 48, which is convenient for later reset. When the pulling rod 49 moves, it will drive the sleeve 54 to move. The movement of the sleeve 54 causes the pulling piece 55 to move. After the pulling piece 55 contacts the limiting piece 53, the pulling piece 55 will pull the limiting piece 53 to move. Then, through the action of the limiting piece 53, the fixed rod 51 drives the fourth rack 44 to move. Through the action of the fourth rack 44, the spur gear 42 rotates. Furthermore, the rotation of the spur gear 42 drives the third rack 41 to move. Since the fourth rack 44 moves away from the feed pipe 5, the third rack 41 will move towards the feed pipe 5. Therefore, through the action of the third rack 41, the sealing plate 40 gradually inserts into the inside of the feed pipe 5, reducing the feed port, and thus reducing the feed speed.

[0041] In this solution, heat dissipation holes 56 are provided on both the outer shell 1 and the rice milling bin 2. Through the arrangement of the heat dissipation holes 56, the rice milling bin 2 can be effectively cooled.

[0042] Working principle: When milling paddy rice, start the motor 23 and the milling bin 2. At this time, the paddy rice is conveyed to the lower hopper 31 through the feeding hopper 6 and the feeding pipe 5. Due to the start of the motor 23, the driving shaft 25 will rotate through the coupling 24. When the driving shaft 25 rotates, it will drive the incomplete gear 36 to rotate. By the rotation of the incomplete gear 36, the first rack 35 and the second rack 37 engaged with it will move. When the incomplete gear 36 meshes with the first rack 35, it will drive the first rack 35 to move towards the side of the housing 1. Therefore, through the connecting column 33 and the connecting plate 38, the lower hopper 31 and the second rack 37 will be driven to move. However, when the incomplete gear 36 meshes with the second rack 37, it will drive the second rack 37 to move in the opposite direction. At this time, through the connecting plate 38 and the connecting column 33, the lower hopper 31 will move in the reverse direction. Therefore, when the incomplete gear 36 meshes with the first rack 35 and the second rack 37 respectively, the lower hopper 31 moves in opposite directions twice, so that the lower hopper 31 swings left and right, evenly spreading the paddy rice on the first screen 8. After the paddy rice reaches the first screen 8, since the first screen 8, the second screen 9, and the third screen 10 are connected to each other and are inclined, the paddy rice will fall from the first screen 8 to the third screen 10. During this process, since the mesh apertures of the first screen 8, the second screen 9, and the third screen 10 gradually increase, the paddy rice is classified through different apertures, so that paddy rice with different particle sizes enters the three groups of milling bins 2 respectively for milling. During this process, since the driving shaft 25 rotates, the cam 19 will rotate. Through the rotation of the cam 19, the roller 18 will move up and down. When the cam 19 rotates close to the roller 18 and squeezes it, the roller 18 will move upward. When the roller 18 moves upward, it will pull the first screen 8 upward through the fixing frame 16. The first screen 8, the second screen 9, and the third screen 10 are connected to each other, so that the second screen 9 and the third screen 10 will move upward accordingly. When the first screen 8, the second screen 9, and the third screen 10 move upward, they will drive the connecting block 29 to move upward. Through the connecting block 29, the sliding column 28 will move upward. Through the sliding column 28, the tension spring will be stretched. When the cam 19 moves away from the roller 18, the roller 18 will reset due to the tension spring and gravity, so that the first screen 8, the second screen 9, and the third screen 10 will vibrate up and down through the rotation of the cam 19, thus facilitating the paddy rice to enter the three groups of milling bins 2 respectively through the first screen 8, the second screen 9, and the third screen 10.

[0043] During the rice milling process, after the paddy enters the interior of the outer shell 1, due to the inclination of the first sieve 8, the second sieve 9, and the third sieve 10, the paddy will gradually accumulate at the top of the third sieve 10. During the accumulation process, due to the gravity of the paddy, the moving plate 46 will move. Through the movement of the moving plate 46, the moving column 47 and the pulling rod 49 will move. The movement of the moving column 47 will stretch the second tension spring 48, facilitating later reset. When the pulling rod 49 moves, it will drive the sleeve 54 to move. Through the movement of the sleeve 54, the pulling piece 55 will move. After the pulling piece 55 contacts the limiting piece 53, the pulling piece 55 will pull the limiting piece 53 to move. Then, through the action of the limiting piece 53, the fixed rod 51 will drive the fourth rack 44 to move. Through the action of the fourth rack 44, the spur gear 42 will rotate. Furthermore, through the rotation of the spur gear 42, the third rack 41 will move. Since the fourth rack 44 moves away from the feed pipe 5, the third rack 41 will move towards the feed pipe 5. Therefore, through the action of the third rack 41, the sealing plate 40 will gradually insert into the interior of the feed pipe 5, reducing the feed opening, and thus reducing the feed speed.

[0044] It should be noted that: by providing the sleeve 54, the pulling piece 55, and the limiting piece 53, the moving plate 46 will drive the sealing plate 40 to move only after moving a certain distance, avoiding adjusting the feed speed before the paddy accumulation has affected the rice milling work, that is, the feed speed will be adjusted only after the paddy on the third sieve 10 has accumulated to a certain extent, avoiding the problem of repeated adjustment.

[0045] It should be noted that: during the reset process, since the feed speed decreases and the accumulation amount of the paddy gradually decreases, the moving plate 46 will gradually reset through the action of the second tension spring 48. However, at the initial stage of the reset of the moving plate 46, the sleeve 54 will slide relative to the limiting piece 53 and will not directly drive the sealing plate 40 to move and reset. Through this design, the accumulated paddy can have a certain processing time. And after the moving plate 46 has been reset for a period of time, the end of the sleeve 54 contacts the limiting piece 53. At this time, it indicates that the amount of paddy inside the outer shell 1 has been gradually processed, and then the sealing plate 40 resets to increase the feed amount.

[0046] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
