Description

Technical Field

[0001] This utility model relates to the field of rice milling machine technology, and in particular to a rotary screen air-blasting sand roller rice milling machine with a polishing structure. Background Technology

[0002] A rice milling machine generally includes a grinding roller and a blowing device. Grains are poured into the rice milling machine, and the grinding roller can lightly crush the rice husk and brown rice, separating the two. The blowing device can then further separate the rice husk and brown rice. Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. After the paddy is hulled, it becomes brown rice. After most of the bran and part of the germ are removed from the brown rice, it becomes rice. The surface of rice grains still has a small amount of bran powder, which affects the appearance, storage quality, and taste of the cooked rice. Therefore, this bran powder needs to be removed through a polishing process.

[0003] In existing rice milling machines, rice bran separates out during the milling process, which can easily cause blockages on the rice sieve. If the airflow from the blower is too strong, it can easily blow out the brown rice; if it is too weak, the effect of blowing out the rice husk is poor, making it difficult to control. To address these issues, application number 202222238816.0 discloses a sand roller air-jet rice milling machine, which includes a housing, a sand roller, a blower, and a rice sieve. The housing has a feed inlet, and the sand roller is rotatably mounted inside the housing and located below the feed inlet. The blower is mounted on the housing and connected to a spray pipe, which extends into the housing. The spray pipe has a spray head aligned with the rice sieve. The housing has two through holes facing each other. A sliding groove is provided inside the housing, in which a cleaning roller slides. The bottom of the cleaning roller can contact the rice sieve. The cleaning roller has two cables, which extend out of the housing through the two through holes.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: during use, the rice is milled and then manually placed in a rice polishing device for polishing, which prevents the rice production process from being continuous, thereby reducing the rice production efficiency and leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a rotary screen air-blast sand roller rice milling machine with a polishing structure, which can not only achieve continuous processing of rice, but also polish different types of rice, and can perform secondary screening of rice and clean and collect impurities and bran powder.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rotary screen air-blasting sand roller rice milling machine with a polishing structure, including a base plate, a rice milling machine body, a polishing mechanism, an adjustment mechanism, and a cleaning mechanism;

[0007] A bracket is provided on the base plate, and the main body of the rice milling machine is fixedly installed on the bracket. A polishing chamber is fixedly installed on the base plate and is connected to the discharge port of the main body of the rice milling machine. A polishing mechanism is set in the polishing chamber and connected to the main body of the rice milling machine.

A cleaning mechanism is provided on the polishing chamber and corresponds to the polishing mechanism. A control module is provided on the polishing chamber. The main body of the rice milling machine, the adjustment mechanism, and the cleaning mechanism are all connected to the control module.

[0008] The polishing mechanism includes a transmission rod, a rice polishing roller, a bevel gear, and a rice polishing cylinder. The transmission rod is rotatably connected to the polishing chamber. Through the coordinated design of the rice milling machine body, polishing chamber, polishing mechanism, adjustment mechanism, cleaning mechanism, and control module, it can not only achieve continuous processing of rice and improve processing efficiency, but also polish different types of rice, improving convenience and applicability. Furthermore, it can perform secondary sieving of rice and clean and collect impurities and bran, making it more practical.

[0009] A further feature of this invention is that a rice polishing roller is fixedly connected to the transmission rod, a bevel gear one is fixedly connected to one end of the transmission rod, a bevel gear two is meshed with the bevel gear one, and the bevel gear two is fixedly sleeved on one end of the rice milling roller on the main body of the rice milling machine. The bevel gear two is driven by the action of one of the two rice milling rollers on the main body of the rice milling machine, and the bevel gear two meshes with the bevel gear one. At the same time, the bevel gear one drives the transmission rod to rotate on the polishing chamber and the rice sieve plate, and the transmission rod drives the rice polishing roller to rotate synchronously. Meanwhile, the rice polishing roller interacts with the rice polishing cylinder to achieve the effect of polishing the rice.

[0010] A further feature of this invention is that a rice polishing cylinder is fitted onto the rice polishing roller to facilitate polishing of the rice. One end of the rice polishing cylinder is fixedly connected to a feeding hopper. The feeding hopper is slidably connected to the polishing chamber and fitted onto the rice polishing roller. The feeding hopper corresponds to the discharge port on the main body of the rice milling machine. The feeding hopper facilitates the entry of the hulled rice into the rice polishing cylinder.

[0011] A further feature of this invention is that the adjusting mechanism includes a motor, a threaded rod, a ring plate, and a fixing block. Two motors are fixedly installed inside the polishing chamber. The output ends of both motors are fixedly connected to threaded rods, and the same ring plate is threaded onto both threaded rods. The ring plate is fixedly sleeved on the rice polishing cylinder. The two threaded rods are synchronously driven by the two motors to rotate synchronously on the two fixing blocks. At the same time, the two threaded rods synchronously drive the ring plate, causing the ring plate to slide within the polishing chamber. Simultaneously, the ring plate drives the rice polishing cylinder to move synchronously, and the rice polishing cylinder drives the feed hopper to slide within the polishing chamber. This allows the rice polishing cylinder and the rice polishing roller to correspond to different positions, thereby adjusting the gap between the rice polishing cylinder and the rice polishing roller. This facilitates polishing different types of rice, improving convenience and applicability.

[0012] A further feature of this invention is that the ring plate is slidably connected to the polishing chamber, one end of each of the two threaded rods is rotatably connected to a fixing block, both fixing blocks are fixedly connected to the polishing chamber, and both motors are connected to the control module, which controls and drives the two motors.

[0014] A further feature of this invention is that the vacuum cleaner is fixedly installed on the polishing chamber, one end of the vacuum cleaner is sealed with a suction pipe, and one end of the suction pipe is sealed with the polishing chamber. The vacuum cleaner, driven by the vacuum cleaner and the suction pipe, draws air from the polishing chamber. The resulting airflow carries impurities sieved by the rice sieve plate and bran powder dropped by the rice polishing roller and the rice polishing cylinder through the suction pipe into the vacuum cleaner, thereby achieving the purpose of sucking up and collecting the impurities and bran powder, and ultimately cleaning the polishing chamber.

[0015] A further feature of this invention is that the vacuum cleaner is connected to the control module, and the control module controls and drives the vacuum cleaner. One end of the suction pipe is located below the rice sieve plate, and the rice sieve plate corresponds to the rice polishing cylinder and is detachably connected.

[0016] A further feature of this invention is that the polishing chamber is equipped with a discharge pipe, which corresponds to the rice sieve plate, and the polished rice is discharged through the action of the discharge pipe.

[0017] A further feature of this invention is that a bearing is fixedly sleeved on the transmission rod, and the outer wall of the bearing is fixedly connected to the polishing chamber to facilitate the rotation of the transmission rod. A fixing plate is rotatably connected to the transmission rod, and the fixing plate is connected to the main body of the rice milling machine to improve stability.

[0018] The beneficial effects of this utility model are as follows: through the coordinated design of the rice milling machine body, polishing chamber, polishing mechanism, adjustment mechanism, cleaning mechanism and control module, it can not only achieve the effect of continuous processing of rice and improve processing efficiency, but also achieve the effect of polishing different types of rice, improving convenience and applicability.

[0027] Reference Figure 1-4 A rotary screen air-blasting sand roller rice milling machine with a polishing structure includes a base plate 1, a rice milling machine body 3, a polishing mechanism, an adjustment mechanism, and a cleaning mechanism;

[0028] A support 2 is provided on the base plate 1, and the main body 3 of the rice milling machine is fixedly installed on the support 2. A polishing chamber 4 is fixedly installed on the base plate 1. The polishing chamber 4 is connected to the discharge port of the main body 3 of the rice milling machine.

[0030] In this embodiment, a rice polishing roller 6 is fixedly connected to the transmission rod 5, and a bevel gear 7 is fixedly connected to one end of the transmission rod 5. A bevel gear 2 is meshed with the bevel gear 7. The bevel gear 2 is fixedly sleeved on one end of the rice milling roller on the rice milling machine body 3. The bevel gear 2 is driven by the action of one of the two rice milling rollers on the rice milling machine body 3, so that the bevel gear 2 meshes with the bevel gear 7. At the same time, the bevel gear 7 drives the transmission rod 5 to rotate on the polishing chamber 4 and the rice sieve plate 14. Simultaneously, the transmission rod 5 drives the rice polishing roller 6 to rotate synchronously. At the same time, the rice polishing roller 6 interacts with the rice polishing cylinder 8 to achieve the effect of polishing the rice.

[0031] In this embodiment, a rice polishing cylinder 8 is fitted on the rice polishing roller 6 to facilitate polishing of the rice. One end of the rice polishing cylinder 8 is fixedly connected to a feeding hopper 9. The feeding hopper 9 is slidably connected to the polishing chamber 4 and fitted on the rice polishing roller 6.

The ring plate 10 is fixedly sleeved on the rice polishing cylinder 8. The two threaded rods 12 rotate synchronously on the two fixing blocks 13 through the synchronous drive of the two motors 11. At the same time, the two threaded rods 12 synchronously drive the ring plate 10 through the threaded transmission, so that the ring plate 10 slides in the polishing chamber 4. At the same time, the ring plate 10 drives the rice polishing cylinder 8 to move synchronously. Simultaneously, the rice polishing cylinder 8 drives the feed hopper 9 to slide in the polishing chamber 4, so that the rice polishing cylinder 8 and the rice polishing roller 6 correspond to different positions, thereby achieving the purpose of adjusting the gap between the rice polishing cylinder 8 and the rice polishing roller 6, and thus achieving the effect of convenient polishing of different types of rice, improving convenience and applicability.

[0033] In this embodiment, the ring plate 10 is slidably connected to the polishing chamber 4, and one end of each of the two threaded rods 12 is rotatably connected to a fixing block 13.

[0034] In this embodiment, the cleaning mechanism includes a rice sieve plate 14, a dust suction pipe 15, and a vacuum cleaner 16. The rice sieve plate 14 is fixedly installed inside the polishing chamber 4. One end of the transmission rod 5 is rotatably connected to the rice sieve plate 14. The polished rice is discharged through the bottom of the rice polishing cylinder 8 and falls onto the rice sieve plate 14. Then, the rice is subjected to a secondary sieving effect through the action of the rice sieve plate 14, thereby improving the quality of the rice.

[0035] In this embodiment, the vacuum cleaner 16 is fixedly installed on the polishing chamber 4. One end of the vacuum cleaner 16 is sealed and connected to the suction pipe 15. One end of the suction pipe 15 is sealed and connected to the polishing chamber 4. The air in the polishing chamber 4 is extracted by the drive of the vacuum cleaner 16 and the action of the suction pipe 15. The resulting airflow carries the impurities screened by the rice sieve plate 14 and the bran powder that falls off the rice by the rice polishing roller 6 and the rice polishing cylinder 8 through the suction pipe 15 into the vacuum cleaner 16, thereby achieving the purpose of sucking up and collecting the impurities and bran powder, and thus achieving the effect of cleaning the polishing chamber 4.

[0036] In this embodiment, the vacuum cleaner 16 is connected to the control module 17, and the control module 17 controls and drives the vacuum cleaner 16. One end of the suction pipe 15 is located below the rice sieve plate 14, which corresponds to the rice polishing cylinder 8 and is detachably connected.

[0037] In this embodiment, the polishing chamber 4 is equipped with a discharge pipe 18, which corresponds to the rice sieve plate 14. The polished rice is discharged through the function of the discharge pipe 18.

[0038] In this embodiment, a bearing is fixedly sleeved on the transmission rod 5. The outer wall of the bearing is fixedly connected to the polishing chamber 4 to facilitate the rotation of the transmission rod 5. A fixing plate is rotatably connected to the transmission rod 5 and is connected to the rice milling machine body 3 to improve stability.

[0039] Working principle: During use, the control module 17 drives and controls the rice milling machine body 3, the electric motor 11, and the vacuum cleaner 16.

[0040] First, the raw material is fed into the rice milling machine body 3 through the feed inlet at the top of the rice milling machine body 3, and the raw material is dehulled by the rice milling machine body 3. Then, it is discharged into the polishing chamber 4 through the discharge outlet on the rice milling machine body 3. Finally, the rice is polished by the polishing mechanism in the polishing chamber 4, thereby achieving the effect of continuous processing of rice feed and improving processing efficiency.

[0041] Meanwhile, the action of one of the two rice milling rollers on the main body 3 of the rice milling machine drives the second bevel gear, which meshes with the first bevel gear 7. At the same time, the first bevel gear 7 drives the transmission rod 5 to rotate on the polishing chamber 4 and the rice sieve plate 14. Simultaneously, the transmission rod 5 drives the rice polishing roller 6 to rotate synchronously. At the same time, the rice polishing roller 6 interacts with the rice polishing cylinder 8, thereby achieving the effect of polishing the rice.

[0042] Then, the polished rice is discharged through the bottom of the rice polishing cylinder 8 and falls onto the rice sieve plate 14. After that, the rice is subjected to secondary sieving through the rice sieve plate 14, thereby improving the quality of the rice.

[0043] At the same time, the air in the polishing chamber 4 is extracted by the drive of the vacuum cleaner 16 and the action of the suction pipe 15. The resulting airflow carries the impurities screened by the rice sieve plate 14 and the bran powder that is cleaned off by the rice polishing roller 6 and rice polishing cylinder 8 into the vacuum cleaner 16 through the suction pipe 15. This achieves the purpose of sucking up and collecting the impurities and bran powder, thereby achieving the effect of cleaning the polishing chamber 4.

[0044] Then, the polished rice is discharged through the discharge pipe 18.

[0045] The synchronous drive of two electric motors 11 causes two threaded rods 12 to rotate synchronously on two fixed blocks 13. At the same time, the two threaded rods 12 synchronously drive the ring plate 10, causing the ring plate 10 to slide within the polishing chamber 4. Simultaneously, the ring plate 10 drives the rice polishing cylinder 8 to move synchronously, and the rice polishing cylinder 8 drives the feed hopper 9 to slide within the polishing chamber 4. This allows the rice polishing cylinder 8 and the rice polishing roller 6 to correspond to different positions, thereby adjusting the gap between the rice polishing cylinder 8 and the rice polishing roller 6. This facilitates the polishing of different types of rice, improving convenience and applicability.

[0046] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, it not only achieves continuous processing of rice, improving processing efficiency, but also polishes different types of rice, enhancing convenience and applicability. Furthermore, it enables secondary sieving of rice and the cleaning and collection of impurities and bran, making it more practical.
