Description

Technical Field

[0001] This utility model belongs to the field of rice milling machine technology, specifically a low-temperature rice milling machine that can quickly clean internal residues. Background Technology

[0002] As people's living standards improve, their requirements for rice quality are becoming increasingly stringent. Low-temperature rice milling technology has emerged to meet this need. It can effectively control the temperature during the rice milling process, reducing the loss of nutrients and quality degradation caused by high temperatures, and preserving the nutrition and taste of rice to the greatest extent. At the same time, the efficiency of cleaning residue inside the rice milling machine is directly related to the continuous working capacity of the equipment, the subsequent processing quality of rice, and the service life of the equipment.

[0003] There are many types of rice milling machines on the market, such as rice hulling and rice milling machines and air-jet rice milling machines. These machines can convert paddy into rice to a certain extent. Rice hulling and rice milling machines integrate the two steps of paddy hulling and rice milling, which improves processing efficiency. Air-jet rice milling machines assist in rice milling and remove some heat and bran by spraying air into the rice milling chamber.

[0004] However, existing rice milling machines have limited means of cleaning rice bran. Some machines rely solely on fans to extract air, which makes it difficult to completely remove the rice bran adhering to the inner walls of the equipment and the rice milling components. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a low-temperature rice milling machine that can quickly clean internal residues, solving the problem that existing rice milling machines have limited means of cleaning rice bran, and some equipment only relies on fans to extract air, making it difficult to completely remove rice bran adhering to the inner wall of the equipment and the rice milling parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature rice milling machine capable of quickly cleaning internal residue, comprising an outer barrel, a feeding cylinder fixedly connected inside the outer barrel, a feeding port provided at the top of the feeding cylinder, the top of the feeding port penetrating the outer barrel, a side plate movably connected to the other side of the outer barrel, a rice milling cylinder rotatably connected between the feeding cylinder and the side plate, a motor fixedly connected to one side of the outer barrel, a rice milling roller coaxially fixedly connected to the output end of the motor, the rice milling roller being located inside the rice milling cylinder, a first discharge port rotatably connected to the side of the rice milling cylinder away from the motor, and an opening at the bottom of the outer barrel. The outer barrel is provided with a second discharge port. Multiple sets of scrapers for use with the rice milling cylinder are fixedly connected to the inner side of the outer barrel. The scrapers are in contact with the outer wall of the rice milling cylinder. A toothed ring is fixedly connected to the outer side of the rice milling cylinder in a symmetrical structure. A gear is rotatably connected to the bottom of the outer barrel. The gear is located below the toothed ring and meshes with the toothed ring. A drive mechanism for use with the gear is provided at the bottom of the outer barrel. Multiple sets of exhaust pipes are provided at the top of the outer barrel. Multiple sets of nozzles are provided inside the exhaust pipes. The exhaust pipes are located above the rice milling cylinder.

Detailed Implementation

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-5 As shown, this utility model provides a technical solution:

[0022] A low-temperature rice milling machine capable of quickly cleaning internal residue includes an outer barrel 1. A feeding cylinder 11 is fixedly connected inside the outer barrel 1. A feeding port 8 is located at the top of the feeding cylinder 11, with the top of the feeding port 8 penetrating through the outer barrel 1. A side plate 10 is movably connected to the other side of the outer barrel 1. A rice milling cylinder 12 is rotatably connected between the feeding cylinder 11 and the side plate 10. A motor 3 is fixedly connected to one side of the outer barrel 1. A rice milling roller 15 is coaxially fixedly connected to the output end of the motor 3. The rice milling roller 15 is located inside the rice milling cylinder 12. A first discharge port 13 is rotatably connected to the side of the rice milling cylinder 12 away from the motor 3. A second discharge port 18 is opened at the bottom of the outer barrel 1. Multiple sets of scrapers 20 are fixedly connected to the inner side of the bucket 1 and are used in conjunction with the rice milling cylinder 12. The scrapers 20 are in contact with the outer wall of the rice milling cylinder 12. A toothed ring 17 is fixedly connected to the outer side of the rice milling cylinder 12 in a symmetrical structure. A gear 16 is rotatably connected to the bottom of the outer bucket 1. The gear 16 is located below the toothed ring 17 and meshes with the toothed ring 17. A drive mechanism for the gear 16 is provided at the bottom of the outer bucket 1. Multiple sets of exhaust pipes 14 are provided at the top of the outer bucket 1. Multiple sets of nozzles are provided inside the exhaust pipes 14. The exhaust pipes 14 are located above the rice milling cylinder 12. An air inlet 9 is installed at the top of the exhaust pipes 14 and penetrates the top of the outer bucket 1.

[0023] Specifically, rice enters the feeding cylinder 11 through the feeding port 8, and then enters the rice milling cylinder 12. The motor 3 starts, and its output end drives the rice milling roller 15 to rotate, grinding the rice in the rice milling cylinder 12 and removing the outer shell and part of the bran. Rice bran is produced in this process. The drive mechanism at the bottom of the outer barrel 1 operates, driving the gear 16 to rotate. Since the gear 16 meshes with the gear ring 17, which is fixed on the outside of the rice milling cylinder 12, the rotation of the gear 16 causes the rice milling cylinder 12 to rotate around its axis. During the rotation of the rice milling cylinder 12, the cylinder wall continuously contacts the scraper 20 fixed on the inside of the outer barrel 1. The scraper 20 removes rice bran adhering to the rice milling cylinder. Rice bran on the outer wall of the rice milling cylinder 12 is scraped off, and air is introduced through the air inlet 9. The air is sprayed downwards through multiple sets of nozzles in the exhaust pipe 14. The airflow can blow away the rice bran raised during the rice milling process, and also blow up the rice bran scraped off by the scraper 20 to the bottom of the rice milling cylinder 12 and the bottom of the outer barrel 1, making it easier for it to be discharged through the second discharge port 18. The milled rice is discharged from the first discharge port 13, while the rice bran is mainly discharged from the second discharge port 18. The scraper 20, which is fixed to the inner side of the outer barrel 1, always maintains contact with the outer wall of the rice milling cylinder 12. When the rice milling cylinder 12 rotates under the drive of the gear 16, the scraper 20 can continuously scrape off the rice bran adhering to the outer wall of the rice milling cylinder 12.

[0024] The nozzles inside the exhaust pipe 14 spray air downwards, and the resulting airflow can effectively blow away the rice bran generated and raised during the rice milling process. This prevents the rice bran from scattering around inside the rice milling cylinder 12 and re-adhering to the rice or the inner wall of the equipment, ensuring a clean rice milling environment and improving the purity of the rice. The airflow can also further blow up the rice bran scraped to the bottom by the scraper 20, making it easier to discharge from the second discharge port 18. This prevents the rice bran from accumulating at the bottom of the equipment, greatly reducing the workload of manually cleaning the rice bran at the bottom. Moreover, with the assistance of airflow, the rice bran discharge is smoother, improving the efficiency of rice bran cleaning and helping to improve the continuity and production efficiency of the entire rice milling production process.

[0025] The drive mechanism includes a drive wheel 5. The drive wheel 5 is fixedly connected to the outer side of the output end of the motor 3. The outer barrel 1 is rotatably connected to a driven wheel 6 on one side of the motor 3. The driven wheel 6 is located below the drive wheel 5, and a connecting shaft is fixedly connected to the driven wheel 6 and the gear 16 on the same axis. A transmission belt 7 is provided on the outer side of the drive wheel 5 and the driven wheel 6.

[0026] Specifically, the drive mechanism uses the drive wheel 5 at the output end of the motor 3 to drive the driven wheel 6 to rotate via the transmission belt 7. Since the driven wheel 6 and the gear 16 are fixed coaxially through the connecting shaft, the power of the motor 3 can be stably transmitted to the gear 16, thereby driving the gear ring 17 and the rice milling cylinder 12 that mesh with the gear 16 to rotate.

[0027] A protective shell 19 is fixedly installed on the top of the outer tub 1. The gear 16 and the connecting shaft are located inside the protective shell 19. Support legs 2 are provided on both sides of the bottom of the outer tub 1 in a symmetrical structure. Rubber pads are provided at the bottom of the support legs 2. A fixing frame 4 is installed on one side of the outer tub 1. The inner side of the fixing frame 4 is fixedly connected to the motor 3.

[0028] Specifically, the protective shell 19 can block external dust, impurities, etc. from entering, preventing them from adhering to the gear 16 and connecting shaft, reducing wear. The rubber pads at the bottom of the support legs 2 can absorb and disperse vibration energy when the motor 3 is running and the equipment is working.

[0029] The working principle of this utility model is as follows:

[0030] First, rice enters the feeding cylinder 11 through the feeding port 8, and then falls into the rice milling cylinder 12, completing the feeding process and preparing for the rice milling process.

[0031] Secondly, the motor 3 starts, and its output end drives the coaxially fixed rice milling roller 15 to rotate, which grinds the rice in the rice milling cylinder 12, removing the outer shell and part of the bran of the rice. In this process, rice bran is produced. At the same time, the drive wheel 5 fixed on the outside of the output end of the motor 3 drives the driven wheel 6 to rotate through the transmission belt 7. The driven wheel 6 and the gear 16 are coaxially fixed through the connecting shaft, thereby transmitting the power of the motor 3 to the gear 16. The rotation of the gear 16 drives the gear ring 17 that meshes with it, thereby causing the rice milling cylinder 12 to rotate around the axis. When the rice milling cylinder 12 rotates, the cylinder wall is in continuous contact with the scraper 20 fixed on the inside of the outer barrel 1. The scraper 20 scrapes off the rice bran attached to the outer wall of the rice milling cylinder 12.

[0032] It is worth mentioning that gas is input through the air inlet 9 and sprayed downwards through multiple sets of nozzles in the exhaust pipe 14. On the one hand, the airflow blows away the rice bran raised during the rice milling process, ensuring a clean rice milling environment and improving the purity of the rice; on the other hand, it blows up the rice bran scraped down to the bottom by the scraper 20, making it easier to be discharged from the second discharge port 18 opened at the bottom of the outer barrel 1, improving the rice bran cleaning efficiency, reducing the amount of manual cleaning work, and ensuring the continuity of the rice milling production process. The milled rice is discharged from the first discharge port 13, which is rotatably connected to the side of the rice milling cylinder 12 away from the motor 3.

[0033] Finally, the protective shell 19 fixedly installed on the top of the outer barrel 1 prevents external dust and impurities from entering, protects the internal gears 16 and connecting shafts, and reduces wear. The support legs 2 symmetrically arranged on both sides of the bottom of the outer barrel 1, and the bottom rubber pads absorb and disperse vibration energy when the motor 3 is running and the equipment is working, thus enhancing the stability of the equipment. The fixing bracket 4 installed on one side of the outer barrel 1 stabilizes the motor 3 and ensures stable power transmission.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
