Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, specifically to a rice seed storage device. Background Technology
[0002] Rice is a cereal crop belonging to the genus Oryza, with the representative species being *Rhizophora*. Rice originated in China and India, and its cultivation dates back 7,000 years to the ancestors of the Yangtze River basin in China. The grain produced by rice is paddy rice, which, after the husk is removed, is called brown rice. Milling away the bran layer from brown rice yields polished rice. Nearly half the world's population relies on rice as their staple food. In the process of researching rice seeds, storage devices are generally used to store them for later research and replanting.
[0003] Rice seeds are typically stored in canister-like containers. During storage, the seeds continuously respire, consuming oxygen and releasing carbon dioxide. If the container is completely sealed, prolonged storage will reduce the oxygen content inside, causing the seeds to enter an anaerobic respiration state, producing alcohol that poisons the cells, and simultaneously reducing the germination rate. Traditional storage canisters lack ventilation, preventing the heat generated by seed respiration from dissipating, which can raise the internal temperature, accelerate seed physiological activity, and shorten storage life. Although heat dissipation and ventilation can be achieved by removing the top cover of the storage canister, adult insects such as rice weevils and grain borers can easily enter through the container opening. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a rice seed storage device that solves the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a rice seed storage device, comprising a storage tank and a cover plate disposed above the top opening of the storage tank. A retaining ring is fixedly connected to the bottom of the cover plate, and the lower end of the retaining ring is inserted into the opening, with the retaining ring abutting against the inner wall of the opening. The surface area of the cover plate is larger than the surface area of the opening. Multiple circumferentially distributed vents are provided on the cover plate. Multiple circumferentially distributed driven gears are rotatably inserted into the bottom of the cover plate via a rotating shaft. A baffle is also fixedly connected to the rotating shaft, which is used to close or open the vents. A filter screen is also threaded onto the bottom end of the retaining ring.
[0008] Preferably, a synchronous drive assembly is also provided at the center of the cover plate, which can drive multiple driven gears to rotate.
[0009] Preferably, the synchronous drive assembly includes a drive gear located below the cover plate, with a rotating shaft fixedly connected to the upper end of the drive gear. The upper end of the rotating shaft passes through the cover plate and is fixedly connected to a knob. The rotating shaft is rotatably inserted into the cover plate.
[0010] Preferably, the storage tank is further provided with a conveying assembly for lifting rice seeds. The conveying assembly includes an outer cylinder located inside the storage tank. A rotatable auger is provided inside the outer cylinder. The lower end of the auger is rotatably inserted into the bottom wall of the storage tank. The lower end of the auger extends to the outside of the storage tank and is fixedly connected to a rotating ring. A guide ring is fixedly connected to the upper end of the outer cylinder for guiding the rice seeds at the top.
[0011] Preferably, a support rod is fixedly connected between the outer circumferential sidewall of the outer cylinder and the inner wall of the storage tank, and the support rod is inclined.

[0013] (III) Beneficial Effects
[0014] This utility model provides a rice seed storage device, which has the following beneficial effects:
[0015] 1. In this utility model, a gas detector and a temperature and humidity meter are used to monitor the data inside the storage tank regularly. When the data exceeds the standard, the knob can be turned to drive the drive gear to rotate. The drive gear drives multiple driven gears to rotate, and the driven gears drive the corresponding baffles to rotate. The baffles are moved away from the vent. At this time, carbon dioxide and heat can be removed from the inside of the storage tank, and ventilation can increase the oxygen concentration inside the storage tank. In addition, a stainless steel filter screen can prevent adult insects from entering the storage tank.
[0016] 2. In this utility model, by rotating the rotating ring, the auger is driven to rotate, and the auger lifts the rice seeds, so that the rice seeds at the bottom are transferred to the top. After the bottom seeds are lifted to the top by the auger, they fall naturally by gravity, forming a cycle. At the same time, the compact state of the seed accumulation is broken, which helps the seeds in both the upper and lower layers to fully release carbon dioxide and heat. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a rice seed storage device, including a storage tank 1 and a cover plate 2 set above the top opening of the storage tank 1. A ring 3 is fixedly connected to the bottom of the cover plate 2, and the lower end of the ring 3 is inserted into the opening. The ring 3 abuts against the inner wall of the opening. The surface area of the cover plate 2 is larger than the surface area of the opening. Multiple circumferentially distributed vents 201 are opened on the cover plate 2. Multiple circumferentially distributed driven gears 8 are inserted into the bottom of the cover plate 2 through a rotating shaft 10. A baffle 9 is also fixedly connected to the rotating shaft 10. The baffle 9 is used to close or open the vents 201. A filter screen 4 is also threadedly installed at the bottom end of the ring 3, so that the filter screen 4 can be disassembled, the inner and outer sides of the filter screen 4 can be cleaned, and the driven gears 8 can be routinely maintained.
[0026] The data inside the storage tank 1 is monitored using a gas detector and a temperature and humidity meter. The equipment can be installed on the circumferential side wall of the storage tank 1. The above-mentioned equipment is existing technology and will not be described in detail. After monitoring, when the preset value is exceeded (the upper limit of the safe storage temperature for seeds is 25℃. If the O2 concentration further drops to ≤15%, accompanied by an increase in CO2 concentration, when the CO2 concentration is ≥1.5%, ventilation needs to be started to remove CO2, which is common knowledge; it can also be set according to specific circumstances), multiple driven gears 8 are driven to rotate. The driven gears 8 drive the baffle 9 to rotate, and the baffle 9 no longer closes the vent 201, so as to achieve the purpose of heat dissipation and carbon dioxide removal. The bottom end of the insertion ring 3 is also threaded with a filter screen 4, which can prevent adult insects from entering the interior of the storage tank 1.
[0027] In addition, an exhaust fan can be installed at the vent 201 to promote the discharge of carbon dioxide and heat from inside the storage tank 1 and improve efficiency.
[0028] See Figure 1 and Figure 3 A synchronous drive assembly is also provided at the center of the cover plate 2, which can drive multiple driven gears 8 to rotate.
[0029] See Figure 3 The synchronous drive component includes a drive gear 6 located below the cover plate 2. A rotating shaft 7 is fixedly connected to the upper end of the drive gear 6. The upper end of the rotating shaft 7 passes through the cover plate 2 and is fixedly connected to a knob 5. The rotating shaft 7 is rotatably inserted into the cover plate 2.
[0030] By rotating knob 5, the driving gear 6 is driven to rotate, which in turn drives multiple driven gears 8 to rotate. The driven gears 8 then drive the corresponding baffles 9 to rotate, and the baffles 9 are moved away from the vent 201. At this time, carbon dioxide and heat can be removed from the inside of the storage tank 1 (diffusion driven by concentration difference). The stainless steel filter screen 4 can prevent adult insects from entering the storage tank 1. The filter screen 4 can be removed from the lower end of the insert ring 3, so that the inner and outer sides of the filter screen 4 can be cleaned, and the driven gears 8 and driving gear 6 can be maintained routinely.
[0031] See Figure 1 and Figure 6 The storage tank 1 is also equipped with a conveying assembly for lifting rice seeds. The conveying assembly includes an outer cylinder 15 located inside the storage tank 1. A rotatable auger 11 is installed inside the outer cylinder 15. The lower end of the auger 11 is rotatably inserted into the bottom wall of the storage tank 1. The lower end of the auger 11 extends to the outside of the storage tank 1 and is fixedly connected to a rotating ring 12. A guide ring 14 is fixedly connected to the upper end of the outer cylinder 15 for guiding the rice seeds at the top.
[0032] By rotating the rotating ring 12, the auger 11 is driven to rotate, and the auger 11 lifts the rice seeds, so that the rice seeds at the bottom are transferred to the top. After the bottom seeds are lifted to the top by the auger 11, they fall naturally along the guide ring 14 by gravity, forming a cycle. At the same time, the compact state of the seed accumulation is broken, which helps the seeds in both the upper and lower layers to fully release carbon dioxide and heat.
[0033] The spiral blades of the Screw Cone 11 are rounded to prevent sharp edges from scratching the seed coat; the blade surface is coated with a food-grade silicone coating to reduce the coefficient of friction between the seed and the metal; the blade surface can also be fitted with elastic buffer strips that can deform with the resistance of the seed to reduce hard compression and reduce wear between the seed and the seed.
[0034] See Figure 1 A support rod 13 is fixedly connected between the outer circumferential side wall of the outer cylinder 15 and the inner wall of the storage tank 1. The support rod 13 is inclined and is used to support and fix the outer cylinder 15. The inclined setting ensures that rice seeds do not easily accumulate on the surface of the storage tank 1.
[0035] See Figure 1 The storage tank 1 is fixedly connected to a circumferentially distributed support leg 16 at the bottom. There is a gap between the rotating ring 12 and the bottom of the support leg 16, so that the hand has operating space to rotate the rotating ring 12.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
