Technical Field
[0001] This utility model belongs to the technical field of wheat seed storage devices, specifically relating to a sealed constant temperature storage device for wheat seeds. Background Technology
[0002] Wheat is an annual or biennial herbaceous plant belonging to the Poaceae family and the Triticum genus. It is widely cultivated throughout China, with numerous varieties exhibiting varying characteristics. Deep, well-structured soils with a deep topsoil layer are beneficial for water and fertilizer retention, promoting root development. Through long-term development, wheat has become one of the world's most widely distributed, largest-acreage, second-highest-producing, most traded, and most nutritionally valuable grain crops. Seed storage is a crucial step in ensuring seed sowing quality through scientific management. It involves controlling seed metabolism to delay quality deterioration. During storage, seeds continuously respire, consuming their stored organic matter and releasing heat, moisture, and carbon dioxide. Improper storage conditions can lead to heat and moisture accumulation within the seed pile, causing a rapid decline in seed vigor and germination rate, and increasing susceptibility to mold and pests, resulting in the loss of the entire storage area.
[0003] In rural areas, wheat seeds are still stored in traditional warehouses or simple storage facilities, which are susceptible to changes in the external environment and climate. Storage risks are high in areas with high temperature and humidity during the summer or large diurnal temperature variations. Although some improved storage equipment, such as some seed banks with mechanical refrigeration functions, has improved storage conditions to some extent, they often have drawbacks such as complex structure, high energy consumption, and large investment, making them difficult to promote in small and medium-sized seed companies or grassroots units. Furthermore, the airtightness of existing storage devices is inadequate, allowing external air to easily penetrate, and the lack of effective integrated ventilation and sterilization methods is detrimental to the long-term safe storage of seeds.
[0004] In summary, there is an urgent need to develop a wheat seed storage device with a reasonable structural design, low energy consumption, high safety and ease of operation. Therefore, a closed constant temperature storage device for wheat seeds is proposed. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1, such as Figure 1-3 As shown, a sealed, temperature-controlled storage device for wheat seeds includes a storage box 1, which forms the main structure and is used to hold wheat seeds, isolating them from external temperature fluctuations and ensuring a constant internal temperature environment. The storage box 1 is equipped with locking casters 2 at its bottom, providing the storage box 1 with flexible movement and allowing it to be fixed in a designated position. This enhances convenience and facilitates flexible allocation and positioning of storage resources between warehouses and different production units.
[0024] The storage box 1 has an opening cover 3 and a fixed cover 4 on its top. One side of the opening cover 3 is hinged to the top of the storage box 1 via a pivot, allowing for easy access to seeds over a large area and convenient opening of the access port. The fixed cover 4 integrates components such as the vent pipe 6 and the exhaust port 7, and its separate design balances ease of operation and functional integration. The storage box 1 has an arc-shaped bottom plate 5 with ventilation holes. The vent pipe 6 is inserted into the fixed cover 4 and then into the arc-shaped bottom plate 5. The arc-shaped bottom plate 5 is located at the bottom of the storage box 1 and is covered with ventilation holes. It serves two purposes: supporting the seeds and cooperating with the vent pipe 6 to ensure that the introduced air can be evenly diffused throughout the seed layer. The arc-shaped inclined design helps guide the collection of small particles for centralized processing. The vent pipe 6 is inserted from the fixed cover 4 and extends into the space below the arc-shaped bottom plate 5. The vent pipe 6 is a channel for transporting external dry, low-temperature air, introducing the treated gas from the bottom into the seed pile. This creates a directional airflow from bottom to top, ensuring even and thorough ventilation.
[0025] A temperature detector is installed on the curved base plate 5, specifically on the upper surface of the curved base plate 5 that directly contacts the seeds. The sensor probe of the temperature detector is preferably fixed to the center of the curved base plate 5 or another representative area using an embedded or surface-mount method. Signal lines are laid along the inner wall of the container. By placing the temperature detector at this location, the temperature of the lowest layer of the seed storage area can be monitored directly and in real time. Because cold air sinks and heat and moisture generated by seed respiration tend to accumulate here, the temperature at this location is highly representative of the entire storage environment.
[0026] The specific design of the aforementioned key components will be discussed in detail below:
[0027] The inner wall of the storage box 1 is provided with an insulation layer, which is made of materials such as polyurethane foam. The function of the insulation layer is to reduce heat exchange between the inside and outside of the box and effectively reduce energy consumption. A temperature control component electrically connected to a temperature detector is provided on the outside of the storage box 1. The temperature control component includes a semiconductor cooling chip, a heating element 9, and a controller 11.
[0028] The thermoelectric cooler and heating element 9 are embedded in the bottom side wall of the storage box 1. A cooling fan 10 is provided outside the thermoelectric cooler, and a controller 11 is provided on the outer wall of the storage box 1. The controller 11 is electrically connected to a temperature detector. The heating element 9 is preferably attached to the inner wall of the storage box 1. When the ambient temperature is too low, the controller 11 commands the heating element to provide heat to the inside of the storage box 1 to prevent the seeds from suffering low-temperature freezing damage. The cooling fan 10 is installed in conjunction with the hot end of the thermoelectric cooler. The cooling fan 10 provides forced convection, quickly removing the heat generated by the thermoelectric cooler during operation to ensure cooling efficiency. Active heat dissipation ensures continuous and stable operation.
[0029] The controller 11 is located on the outer wall of the storage box 1 and is electrically connected to the temperature sensor, heating element 9, semiconductor cooling element, etc. It receives temperature data and controls the start and stop of cooling, heating and ventilation through built-in logic algorithms such as PID, realizing fully automatic and intelligent control of the storage environment without manual intervention and with high reliability.
[0030] The vent pipe 6 is connected to the air pump, and the top of the fixed cover 4 is provided with an exhaust port 7. The exhaust port 7 is equipped with a one-way valve 8 and an insect-proof and dust-proof screen. The one-way valve 8 is oriented from the inside to the outside. When the vent pipe 6 sends gas into the storage tank 1, the pressure inside the storage tank 1 rises slightly, forcing the exhaust gas rich in moisture and carbon dioxide to be discharged through the exhaust port 7. The one-way valve 8 prevents external air from flowing back in, together forming a "low pressure difference, directional flow" ventilation structure, which maintains the airtightness of the storage tank 1 while refreshing the internal air and expelling moisture.
[0031] A sealing ring is provided at the contact edge between the opening 3 and the storage box 1. Sealing strips are provided at the connection points between the fixed cover 4 and the storage box 1, and between the vent pipe 6 and the fixed cover 4. The sealing ring at the opening 3 is preferably made of silicone, which ensures a reliable and effective seal of the main access ports, preventing external air and moisture from entering. The sealant between the fixed cover 4 and the box body, and between the vent pipe 6 and the fixed cover 4, eliminates leakage points caused by component introduction, reducing the exchange of gas and humidity between the inside and outside of the box.
[0032] The arc-shaped bottom plate 5 is a detachable structure, and it is connected to the bottom of the storage box 1 by clips. This allows for the maintenance and cleaning of the storage box 1. The arc-shaped bottom plate 5 is connected by clips or quick-release screws, enabling quick assembly and disassembly. After the storage season, the arc-shaped bottom plate 5 can be easily removed to clean off any attached impurities and dust.
[0033] The bottom of the fixed cover 4 is equipped with a sterilization component, which is an ultraviolet germicidal lamp. The UVC band ultraviolet germicidal lamp located at the bottom of the fixed cover 4 emits short-wave ultraviolet light within the enclosed space, achieving highly efficient sterilization. This physical sterilization leaves no chemical residue and is safe for the seeds. To avoid harm to operators from ultraviolet light, it is preferable that the controller 11 be set to operate intermittently at timed intervals, or designed to activate only when the lid is completely closed.
[0034] Additional information: The storage box 1 is equipped with a battery and an external power interface on its exterior to power the temperature control component, controller 11, air pump, and ultraviolet germicidal lamp. It operates using external AC power and charges the battery; in situations without AC power or during mobile operation, it switches to battery power.
[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
