Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Seed germination is a crucial step in rice production, directly impacting germination rate and seedling vigor. Traditional germination methods, such as greenhouse stacking and cellar germination, suffer from uneven temperature, difficulty in humidity control, and poor ventilation, easily leading to seed mold and uneven germination. While existing germination chambers offer basic temperature control, they still have the following drawbacks: uneven temperature and humidity distribution within the chamber, with significant differences between the upper and lower layers, and between the center and edges; miscoordination between moisture evaporation and gas circulation, easily causing localized over- or under-humidity; and an inability to flexibly adjust humidity supply according to different germination stages. Therefore, there is an urgent need for a specialized germination device capable of precise environmental control and ensuring uniform germination.

[0035] As attached Figure 1 To be continued Figure 6 As shown, a constant temperature and humidity device for rice seed germination is provided, comprising:

[0036] The box body 1 includes an openable and closable door 110. The inner wall of the box body 1 is provided with several support brackets 2 at vertical intervals. Germination modules are movably arranged on the support brackets 2. The germination modules are pulled and slid on the support brackets 2 through the door 110. Two adjacent sets of germination modules are spaced apart to form a first air channel 11.

[0037] The pull-out germination module design facilitates seed placement and removal as well as equipment cleaning and maintenance; the layered structure enables large-scale germination within a limited space.

[0038] The germination module includes:

[0039] A water storage tray 3 is mounted on the support bracket 2 and includes a water storage tank for providing water vapor.

[0040] A germination tray 5 is placed above the water storage tray 3, and a second air passage 12 is formed between the germination tray 5 and the water storage tray 3.

[0041] A position adjustment module 4 is disposed on the water storage tray 3 and supports the germination tray 5. The position adjustment module 4 adjusts the distance between the germination tray 5 and the water storage tray 3 to adjust the airflow of the second air passage.

[0042] This solution achieves excellent environmental uniformity through its innovative layered air ducts and adjustable spacing structure. The dual airflow channel design of the first air duct 11 and the second air duct 12 ensures a high degree of temperature and humidity consistency throughout the chamber; the adjustable second air duct 12 can precisely control the environmental humidity according to the needs of different seed germination stages.

[0043] It is understandable that, since the water vapor generated in the water storage tray 3 seeps into the rice seeds through the bottom of the germination tray 5, the humidity of the second air channel 12 located at the bottom of the germination tray 5 has a close influence on the germination of the rice seeds. The influence of the humidity of the second air channel 12 on germination is much greater than the influence of the humidity of the first air channel 11 on the rice seeds.

[0044] During the germination process, when the temperature reaches a suitable level and humidity needs to be adjusted, the working method is as follows: when the humidity of the second air channel 12 is too low, the germination tray 5 moves downward closer to the water storage tray 3 through the position adjustment module 4. At this time, the water vapor diffused in the water storage tray can directly pass through the water vapor through hole 51 at the bottom of the germination tray 5 and enter the rice seed. Adjusting the channel cross-sectional area of ​​the second air channel adjusts the gas flow rate of the second air channel.

[0045] When the humidity of the second airway 12 is too high, the germination tray 5 moves upward and further away from the water storage tray 3 through the position adjustment module 4, which increases the distance between the germination tray 5 and the water storage tray. The diffused water vapor will diffuse in all directions. At this time, some of the diffused water vapor in the water storage tray can directly pass through the water vapor through hole 51 at the bottom of the germination tray 5 and enter the rice seeds. The other part is lost and participates in the diffusion of the inward airflow, which indirectly regulates the humidity of the first airway 11, so that the humidity of the first airway and the second airway can be as similar as possible, improve the overall temperature and humidity uniformity in the box, and adjust the channel cross-sectional area of ​​the second airway, that is, adjust the gas flow of the second airway.

[0046] Through the dual design of the first airway 11 and the adjustable second airway 12, a three-dimensional and controllable airflow channel is realized, which fundamentally solves the problem of uneven internal environment in traditional germination boxes, and at the same time provides the ability to finely adjust humidity according to germination needs.

[0047] It is clear that temperature and humidity sensors are installed in both the first airway 11 and the second airway 12 to detect the temperature and humidity in the first and second airways.

[0048] As attached Figure 3 As shown, in some specific embodiments, the water storage tray 3 includes:

[0049] The tray body 30 includes an upward-opening water storage tank;

[0050] Support beam 31, the support beam 31 is separately arranged on both sides of the pallet body 30, and the support beam 31 is arranged corresponding to the support bracket 2;

[0051] The position adjustment module 4 is disposed on the tray body 30 between the two sets of support beams 31, and at least one set of the position adjustment module 4 is disposed along the length direction of the support beams 31. Preferably, two sets of the position adjustment module 4 are disposed along the length direction of the support beams 31 to ensure stable lifting and lowering displacement of the germination tray 5.

[0052] The structure of the water storage tray 5 has been optimized. Through the coordinated design of the support beam and the position adjustment module, the balance between load-bearing stability and functional adjustability has been achieved. This ensures the structural strength of the germination module when it is pulled out, and provides a reliable installation foundation for position adjustment.

[0053] A positioning block 21 is provided on the side of the support beam 31 away from the box door 110 to position the insertion depth of the germination module.

[0054] In some specific embodiments, the pallet body 30 includes a side support plate 32, which is located between the two support beams 31 and disposed at the bottom of the position adjustment module 4 to support the position adjustment module.

[0055] The side support plate provides a dedicated installation platform for the position adjustment module 4, avoiding the direct installation of the adjustment mechanism in the water storage tank, preventing water vapor from affecting the adjustment mechanism, and improving the service life and reliability of the equipment.

[0056] In some specific embodiments, the side support plate 32 is lower than the support beam 31 to form a stepped structure 33, and the top surface of the position adjustment module 4 is not higher than the top surface of the support beam 31 when the position adjustment module 4 is in the minimum stroke state.

[0057] The stepped structure 33 ensures that the position adjustment module does not interfere with the tray pull-out when the stroke is at its minimum, thus guaranteeing the functional integrity of the equipment and avoiding normal use due to structural interference, reflecting the thoughtfulness of the design.

[0058] In some specific embodiments, the position adjustment module 4 is an inflatable airbag. Using an airbag as the position adjustment module provides a simple, reliable, and low-cost adjustment solution. Height can be precisely controlled by adjusting the inflation volume, and it has good cushioning performance, is easy to operate, and is easy to maintain.

[0059] Preferably, the airbag adopts an up-and-down folding airbag structure, which can increase its lifting stroke.

[0060] It should be noted that the airbag body includes an automatically opening and closing sealing valve, used to seal the airbag or release air as needed, thereby adjusting the airbag's height. The airbag is inflated by an air pump, which can be located inside or outside the chamber.

[0061] A distance sensor is installed between the germination tray 5 and the water storage tray 3 to detect the distance between them.

[0062] As attached Figure 6 As shown, in some specific embodiments, the top of the position adjustment module 4 is provided with a magnetic suction component 41, and the bottom of the germination tray 5 is provided with a magnetic suction component 42 corresponding to the magnetic suction component 41; during germination, the magnetic suction component 1 and the magnetic suction component 2 are attracted and connected.

[0063] A magnetic connection method enables reliable connection and convenient separation between the germination tray 5 and the position adjustment module 4. This ensures stability during operation and facilitates separation when removing the germination tray, greatly improving the practicality and ease of maintenance of the equipment.

[0064] In some specific embodiments, the germination tray 5 is a box or tray structure with the opening facing upwards, and the bottom of the germination tray 5 has a number of water vapor passage holes 51.

[0065] The water vapor at the bottom of the germination tray evaporates through holes, ensuring uniform evaporation and allowing the water vapor to act evenly on the seeds, avoiding localized over-wetting or over-drying and guaranteeing uniform germination.

[0066] As attached Figure 2 and attached Figure 4 As shown, in some specific embodiments, the arrangement direction of the two sets of support brackets 2 is a first direction, and the support brackets 2 are all spaced apart from the inner wall of the box 1 in the first direction. An airflow channel is formed between the support brackets 2 and the inner wall of the box on the corresponding side, and the airflow channel is simultaneously connected to the first air passage 11 and the second air passage 12.

[0067] The first air passage 11 and the second air passage 12 are connected by the airflow channel, forming a complete airflow circulation system inside the box, which allows the air to flow fully inside the box and eliminates dead zones in temperature and humidity.

[0068] As attached Figure 1 To be continued Figure 4 As shown, in some specific embodiments, a vertical partition 6 is provided below the top wall of the inner cavity of the box 1, and an air exchange fan 7 is provided on the vertical partition 6. The airflow channels located on both sides inside the box 1 form an airflow circulation through the air exchange fan 7.

[0069] The system employs a forced circulation system with a ventilation fan 7 to actively promote airflow, further enhancing environmental uniformity and ensuring consistent temperature and humidity conditions in every corner.

[0070] In some specific embodiments, a horizontal partition 8 is also provided at the bottom of the vertical partition 6. The horizontal partition 8 is positioned above the topmost germination tray 5, and a first air passage is formed between the horizontal partition 8 and the germination tray.

[0071] The top airflow organization was optimized by using diaphragms, and the circulation path was improved, making the airflow distribution more scientific and reasonable, and further enhancing the accuracy of environmental control.

[0072] In the two airflow channels in the first direction, at least one of them is provided with a heating module 9, which heats the inside of the box to accelerate water vapor evaporation and provide a suitable temperature environment.

[0073] As attached Figure 1 To be continued Figure 6 A specific embodiment is provided: the box body 1 is made of heat-insulating material, and has multiple layers of support brackets 2 inside. Each germination module is supported on the support brackets 2 by the support beams 31 on both sides of the water storage tray 3, and can be pulled out as a whole through the box door 110. The position adjustment module 4 uses an inflatable air bag, and the height of the germination tray 5 is adjusted by controlling the inflation amount. The top of the box body is provided with a vertical partition 6 and a ventilation fan 7 to promote air circulation.
