Description

Technical Field

[0001] This utility model relates to the field of rice milling device technology, and in particular to a rice milling device for rice production. Background Technology

[0002] In the rice milling stage of large-scale rice production, the shortcomings of traditional rice milling equipment significantly impact production efficiency. Among these, the poor separation of rice bran from rice grains is a long-standing and common problem plaguing processing enterprises. In actual production, the milled mixture often falls rapidly, significantly reducing the time the fan's airflow is effective. A large amount of light rice bran fails to be blown away in time, resulting in substantial losses in the primary separation stage. Simultaneously, material often accumulates on the filter screen, forming uneven layers, and in some areas, blockages occur. This not only reduces the effectiveness of rice bran passing through the screen but also requires frequent shutdowns for cleaning, severely hindering continuous production efficiency. Furthermore, many devices lack independent sorting and recycling channels, often resulting in the mixed collection of separated rice bran and rice grains. This increases subsequent sorting costs and wastes the reusable resource of rice bran, leading to considerable economic losses annually due to improper recycling. More importantly, the independent operation of the drive systems for some components results in poor coordination. During peak production periods, the milling, separation, and conveying rhythms are prone to disconnect, causing the overall processing efficiency to drop significantly below design standards, failing to meet the high-efficiency requirements of modern rice production. Utility Model Content

[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art, and to provide a rice milling device for rice production. This device achieves efficient rice milling through the synchronous rotation of two milling rollers, and the gear transmission ensures uniform milling pressure, improving the efficiency of rice hulling. A double-layer inclined plate slows the falling speed of the mixture, prolongs the fan's action time, and enhances the primary separation effect of rice bran. The lower inclined plate guides the material above the filter screen, increasing the contact area with the screen and improving separation accuracy. A gear-driven turntable and slide bar drive the sliding plate to reciprocate, causing the guide plate to spread the material evenly, preventing accumulation on the filter screen surface and making it easier for rice bran to pass through and separate, further improving separation efficiency. A recycling bin and a collection bin respectively collect rice bran and rice grains, achieving material classification and recycling, reducing waste. The overall structure is compact, and all components work together to significantly improve the overall performance of rice milling and separation.

[0004] This utility model also provides a rice milling device for rice production as described above, comprising: a machine housing, a motor fixedly connected to the side surface of the machine housing, a rice milling roller fixedly connected to the output end of the motor, a gear fixedly connected to the end of the rice milling roller away from the motor, a fan provided on the inner side wall of the machine housing, a filter screen fixedly connected to the inner side wall of the machine housing, and a feeding box fixedly connected to the side surface of the machine housing. The gears are connected to a turntable via belt drive. A slide rod is fixedly connected to the side surface of the turntable, and a sliding plate is movably connected to the side surface of the slide rod. A guide plate is fixedly connected to the lower surface of the sliding plate. These components enable efficient rice milling and precise separation. A motor drives the rice milling rollers, and gears ensure synchronization between the two rollers, improving the hulling effect. A fan, in conjunction with a feeding box, separates and conveys some rice bran, while a filter screen filters out the remaining bran, improving purity. The gears, in conjunction with the turntable and slide rod, cause the sliding plate to reciprocate, and the guide plate lays the material evenly, preventing clogging and improving screen penetration efficiency.

[0005] According to the present invention, a rice milling device for rice production includes an inclined plate fixedly connected to the inner side wall of the machine casing, the inclined plate being located below a fan.

[0006] According to the present invention, a rice milling device for rice production includes a second inclined plate fixedly connected to the inner side wall of the machine casing, the second inclined plate being located below the first inclined plate. Rice grains move along the second inclined plate to the filter screen.

[0007] According to the present invention, a rice milling device for rice production includes a recycling box slidably connected to the lower bottom wall of the machine casing, located below the filter screen. The recycling box is used to collect the separated rice bran.

[0008] According to the present invention, a rice milling device for rice production includes a feeding plate fixedly connected to the side surface of the machine casing, and a collection box disposed below the feeding plate. Rice grains are fed into the collection box through the feeding plate.

[0009] According to the present invention, a rice milling device for rice production includes a slider fixedly connected to the side surface of the sliding plate, and the side surface of the slider slidably connected to the machine housing. The slider can be used to restrict the movement direction of the sliding plate and the guide plate, allowing them to slide only along the machine housing.

[0010] According to the present invention, a rice milling device for rice production includes a feeding hopper fixedly connected to the upper surface of the machine casing, and a filter screen slidably connected to the lower surface of the guide plate.

The gear drives the rice milling roller to rotate, thus milling the paddy rice. Beneficial effects

[0012] This rice milling device for rice production utilizes the synchronous rotation of two milling rollers for efficient milling, coupled with gear transmission to ensure uniform milling pressure and improve paddy hulling efficiency. A double-layer inclined plate slows the falling speed of the mixture, extending the fan's action time and enhancing the primary separation effect of rice bran. The lower inclined plate guides the material above the filter screen, increasing the contact area and improving separation accuracy. A gear-driven turntable and slide bar drive the reciprocating motion of the sliding plate, which in turn spreads the material evenly on the guide plate, preventing accumulation on the filter screen surface and facilitating easier separation of rice bran, further improving separation efficiency.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-6This utility model embodiment discloses a rice milling device for rice production, comprising: a machine housing 1, a motor 4 fixedly connected to the side surface of the machine housing 1, a rice milling roller 14 fixedly connected to the output end of the motor 4, a side inner wall of the machine housing 1 rotatably connected to the rice milling roller 14, a gear 8 fixedly connected to the end of the rice milling roller 14 away from the motor 4, a side surface of the machine housing 1 rotatably connected to the gear 8, a fan 15 provided on the side inner wall of the machine housing 1, a filter screen 18 fixedly connected to the side inner wall of the machine housing 1, and a feeding box 2 fixedly connected to the side surface of the machine housing 1. Specifically, when in use, the motor 4 is started to drive the rice milling roller 14 to rotate, and the two rice milling rollers 14 are rotated synchronously through the gear 8 to crush the rice injected into the machine box 1, separating the rice grains from the rice bran to complete the rice milling process. After that, the rice grains and rice bran will fall. Since the rice bran is light, the fan 15 can blow the rice bran into the feeding box 2 after starting, and send it to the inside of the recycling box 7 along the feeding box 2. After that, the rice grains and the rice bran that were not separated by the fan 15 will fall onto the filter screen 18 after falling and slide down the filter screen 18. At this time, the remaining rice bran will fall into the recycling box 7 through the filter screen 18, which improves the separation effect. Gear 8 is connected to turntable 10 via belt 9. The side surface of the housing 1 is rotatably connected to turntable 10. A slide rod 19 is fixedly connected to the side surface of turntable 10. A slide plate 16 is movably connected to the side surface of slide rod 19. A guide plate 17 is fixedly connected to the lower surface of slide plate 16.

[0017] Specifically, while the gear 8 drives the rice milling roller 14 to rotate, the belt 9 also drives the turntable 10 to rotate. At this time, the slide bar 19 on the turntable 10 will drive the slide plate 16 to reciprocate horizontally along the slide groove in the slide plate 16, thereby driving the guide plate 17 to slide along the surface of the filter screen 18. The guide plate 17 will then move the rice grains and rice bran that fall on the filter screen 18 so that they can be spread flat on the filter screen 18, making it easier for the rice bran to pass through the filter screen 18 and separate from the rice grains.

[0018] A first inclined plate 12 is fixedly connected to the inner side wall of the chassis 1. The first inclined plate 12 is located below the fan 15. A second inclined plate 13 is fixedly connected to the inner side wall of the chassis 1. The second inclined plate 13 is located below the first inclined plate 12.

[0019] Specifically, inside the casing 1, inclined plate 12 and inclined plate 13 are arranged sequentially from top to bottom. After being crushed by the rice milling roller 14, the rice grains and rice bran will first fall onto inclined plate 12 and slide down along inclined plate 12 to slow down the falling speed of the rice grains and rice bran, so that the fan 15 can blow the rice bran out better. Then the rice grains and the remaining rice bran will fall onto inclined plate 23 and slide down along inclined plate 23, so that they can be moved to the upper part of the filter screen 18 to increase the contact area with the filter screen 18.

[0020] A recycling bin 7 is slidably connected to the bottom wall of the casing 1. The recycling bin 7 is located below the filter screen 18. A feeding plate 5 is fixedly connected to the side surface of the casing 1. A collection bin 6 is set below the feeding plate 5. A slider 11 is fixedly connected to the side surface of the slide plate 16. The side surface of the slider 11 is slidably connected to the casing 1. A feed hopper 3 is fixedly connected to the upper surface of the casing 1. The lower surface of the guide plate 17 is slidably connected to the filter screen 18.

[0021] Specifically, a recycling box 7 is provided below the filter screen 18, which can collect rice bran that falls through the filter screen 18 and is conveyed by the feeding box 2. The separated rice grains will slide out of the machine box 1 along the feeding plate 5 and fall into the collection box 6 for recycling. A slider 11 is provided on the slide plate 16. When the slide bar 19 moves the slide plate 16, the slider 11 restricts the slide plate 16 to only move the guide plate 17 in the horizontal direction. A feeding hopper 3 is provided above the machine box 1, which can send the paddy rice between the two rice milling rollers 14 for rice milling.

[0022] Working Principle: Rice grains enter the machine housing 1 through the feed hopper 3 and fall between two rice milling rollers 14. The motor 4 is started, driving the rice milling rollers 14 to rotate. The gear 8 causes the two rice milling rollers 14 to rotate synchronously, crushing the rice grains and separating the rice grains from the bran. The crushed mixture first falls onto the inclined plate 12, sliding down it to slow its descent, making it easier for the fan 15 to blow the lighter bran into the feeding box 2, and then to the recycling box 7. The remaining mixture falls onto the inclined plate 13, sliding down it onto the filter screen 18. Simultaneously, the gear 8 drives the turntable 10 to rotate via the belt 9, and the sliding rod 19 moves horizontally back and forth along the sliding groove of the slide plate 16. The slider 11 restricts the movement direction of the slide plate 16, causing the guide plate 17 to slide along the surface of the filter screen 18, spreading the mixture evenly and allowing the remaining bran to pass through the filter screen 18 and fall into the recycling box 7. The separated rice grains slide out along the feeding plate 5 and fall into the collection box 6, completing the rice milling and separation recycling process.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 utility model.
