Description

Technical Field

[0001] This utility model belongs to the field of soybean seed germination experiment technology, specifically relating to a soybean seed germination experiment device. Background Technology

[0002] Soybean seed germination experiments are mainly used for scientific research or teaching. By controlling environmental conditions such as temperature, humidity, and light, the effects of seed vigor, germination rate, gene expression, or stress (such as salinity, alkalinity, and heavy metal stress) on germination are studied. This typically requires the use of a light incubator, a constant temperature and humidity chamber, an autoclave, germination boxes, a data logger, and a microscope. The standard operating procedure is as follows: 1. Select healthy seeds, sterilize them with sodium hypochlorite solution, and rinse them; 2. Place the seeds in a germination box lined with moistened filter paper, setting up experimental groups (e.g., different temperatures / light / treatment solutions) and a control group; 3. Record the number of germinated seeds, radicle length, and any abnormalities daily for 5-7 days; 4. Calculate the germination rate and germination index, and analyze the data. Unlike conventional soybean sprouting (for consumption), this experiment requires precise control of variables (such as light cycle and pH value), the establishment of replicate groups, aseptic operation (to avoid microbial interference), and emphasizes quantitative analysis.

[0003] The germination box is the main container for carrying and cultivating soybean experimental seeds. The core function of the wet filter paper laid inside the germination box is to provide a stable and humid environment for seed germination. The filter paper evenly transfers moisture through capillary action, ensuring that the seeds absorb water, activate, and initiate enzymatic reactions. At the same time, it isolates water accumulation to prevent rotting due to lack of oxygen and maintains air permeability to reduce the risk of mold. The filter paper needs to be kept moist throughout the experiment. Although the constant temperature and humidity chamber can control the environmental humidity of the experimental seeds, it is mainly used to simulate the air humidity and temperature in the natural environment. The moisture on the filter paper will gradually decrease due to absorption and natural evaporation by the experimental seeds. Generally, it needs to be manually replenished every day using a spray bottle or dropper. When there are many control groups, it is troublesome to replenish them one by one. Moreover, manual replenishment needs to be spaced one day apart, which will cause relatively large fluctuations in the humidity value of the filter paper, making it difficult to maintain the relative stability of the filter paper humidity. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a soybean seed germination experimental device to solve the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a soybean seed germination experimental device, comprising a water basin, with multiple sets of L-shaped placement rods equidistantly arranged on the upper inner side of the water basin, each set consisting of two L-shaped placement rods, each set of L-shaped placement rods being symmetrically arranged, and multiple bean sprout boxes being snapped onto the upper side of each set of L-shaped placement rods, the bean sprout boxes having openings on both the upper and lower sides, and support rods symmetrically fixedly arranged on the lower inner side of the bean sprout boxes, with a thin mesh plate placed on the upper side of the support rods, and crossbars fixedly arranged at equal intervals between the support rods, with absorbent ropes evenly placed on the upper side of the crossbars, both ends of the absorbent ropes pointing downwards through the openings of the bean sprout boxes and contacting the bottom inner side of the water basin, and the upper side of the absorbent ropes contacting the lower side of the thin mesh plate.

[0006] The beneficial effects of this invention are as follows: the absorbent rope can continuously absorb water, the lower side of the thin mesh plate contacts the absorbent rope, and the thin mesh plate can have coarse mesh openings, allowing the water on the absorbent rope to seep into the filter paper on the upper side of the thin mesh plate, thereby continuously keeping the filter paper moist without the need for manual replenishment using a spray bottle or dropper. It can automatically keep the filter paper continuously moist without causing relatively large fluctuations in the humidity value of the filter paper, thus facilitating the maintenance of the relative stability of the filter paper humidity and providing a stable and moist environment for soybean seed germination.

[0007] To keep the upper surface of soybean seeds moist;

[0008] As a further improvement to the above technical solution: a waterproof battery box and controller are fixedly installed on one side of the water basin; a fixing frame is fixedly installed on the upper side of the water basin corresponding to each group of L-shaped placement rods; a water guide rod is fixedly installed on the upper side of each fixing frame; spray heads are evenly arranged on the lower side of the water guide rods corresponding to the bean sprout box; the output end of the spray head faces downward; a pump is fixedly installed on the side of the water basin corresponding to each water guide rod; a water suction pipe is connected between the input end of the pump and the bottom of the side of the water basin; and a water delivery pipe is connected between the output end of the pump and the water guide rod.

[0009] The beneficial effects of this improvement are as follows: by setting the pump to start repeatedly at intervals through the controller, the pump draws water from the water basin through the suction pipe, then sends it into the water guide rod through the water delivery pipe, and finally sprays it downward through the spray head, which can regularly spray water on the upper side of the soybean seeds to keep the upper surface of the soybean seeds moist.

[0010] In order to quickly extract experimental soybean seeds;

[0011] As a further improvement to the above technical solution: handles are fixedly installed on both sides of the upper side of the thin mesh plate.

[0012] The beneficial effect of this improvement is that the thin mesh plate can be lifted by the handle frame to quickly remove the experimental soybean seeds.

[0013] To provide desktop isolation and support for the thin stencil;

[0014] As a further improvement to the above technical solution: both ends of the support rod have gaps with the inner wall of the bean sprout box, and support plates are fixedly installed on both sides of the lower side of the thin mesh plate, with the support plates inserted into the gaps.

[0015] The beneficial effects of this improvement are as follows: Soybean seeds need to be removed multiple times during germination and their data needs to be tested using equipment such as microscopes. Directly removing the bean sprout box is inconvenient. Removing the thin mesh plate along with the filter paper makes it easier to quickly remove the soybean seeds, but placing the thin mesh plate directly on the table not only easily wets the table but also makes the underside of the filter paper come into contact with dust and bacteria. By setting up a support plate, the thin mesh plate can be isolated and supported on the table when it is removed.

[0016] To enhance the side ventilation of the bean sprout box;

[0017] As a further improvement to the above technical solution: both sides of the bean sprout box are provided with perforated plates corresponding to the upper side of the filter paper.

[0018] The beneficial effect of this improvement is that it enhances the side ventilation of the bean sprout box.

[0019] To insert the identification card;

[0020] As a further improvement to the above technical solution: an identification shell plate is fixedly installed on the upper middle part of one side surface of the bean sprout box, and the upper side of the identification shell plate is open.

[0021] The beneficial effects of this improvement are: a labeling shell is set up, and a labeling card can be inserted into the inside of the labeling shell, which can display the bean variety information.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0030] like Figure 1 — Figure 5The apparatus shown is a soybean seed germination experimental device, comprising a water basin 1. Multiple sets of L-shaped placement rods 4 are equidistantly arranged on the upper inner side of the water basin 1. Each set contains two L-shaped placement rods 4, and they are symmetrically arranged. Multiple bean sprout boxes 5 are clamped to the upper side of each set of L-shaped placement rods 4. The bean sprout boxes 5 are open at both the top and bottom. Support rods 51 are symmetrically fixed to the lower inner side of each bean sprout box 5. A thin mesh plate 52 is placed on the upper side of each support rod 51. Horizontal rods 56 are equidistantly fixed between the support rods 51. Water-absorbing ropes 57 are evenly placed on the upper side of each horizontal rod 56. Both ends of the water-absorbing ropes 57 extend downwards through the openings of the bean sprout boxes 5 and contact the bottom inner side of the water basin 1. The upper side of the water-absorbing ropes 57 contacts the lower side of the thin mesh plate 52, allowing continuous water absorption. The lower side of the thin mesh plate 52 contacts the water-absorbing ropes 57.The thin mesh plate 52 can have a coarse mesh, allowing water from the absorbent rope 57 to seep into the filter paper 53 on the upper side of the thin mesh plate 52, thus continuously keeping the filter paper 53 moist without the need for manual replenishment using a spray bottle or dropper. It automatically maintains continuous moisture in the filter paper 53 without causing significant fluctuations in its humidity level, ensuring relative stability and providing a stable, humid environment for soybean seed germination. A waterproof battery box 2 and a controller 3 are fixedly installed on one side of the water basin 1. A fixing frame 6 is fixedly installed on the upper side of the water basin 1 corresponding to each set of L-shaped placement rods 4. Each fixing frame 6 has a fixed mounting bracket on its upper side. A water guide rod 7 is provided, and spray heads 8 are evenly arranged on the lower side of the water guide rod 7 corresponding to the bean sprout box 5. The output end of the spray head 8 faces downward. A pump 9 is fixedly installed on the side of the water basin 1 corresponding to the water guide rod 7. A water suction pipe 10 is provided between the input end of the pump 9 and the bottom side of the water basin 1. A water delivery pipe 11 is provided between the output end of the pump 9 and the water guide rod 7. The pump 9 is set by the controller 3 to start repeatedly at regular intervals. The pump 9 draws water from the water basin 1 through the water suction pipe 10, then sends it into the water guide rod 7 through the water delivery pipe 11, and finally sprays it downward through the spray head 8. This can periodically spray water onto the upper side of the soybean seeds. Spray water to keep the upper surface of the soybean seeds moist. Handles 54 are fixedly installed on both sides of the upper side of the thin mesh plate 52. Lifting the thin mesh plate 52 using the handles 54 allows for quick removal of the soybean experimental seeds. Both ends of the support rod 51 have gaps with the inner wall of the bean sprout box 5. Support plates 55 are fixedly installed on both sides of the lower side of the thin mesh plate 52, and these support plates 55 are inserted into the gaps. Since soybean seeds need to be removed multiple times during germination and their data needs to be analyzed using equipment such as microscopes, directly removing the bean sprout box 5 is inconvenient. Removing the thin mesh plate 52 along with the filter paper 53 facilitates quick seed removal, but directly removing the bean sprout box 5 is not ideal. The thin mesh plate 52, when placed on a table, not only easily wets the table surface but also allows the underside of the filter paper 53 to come into contact with dust and bacteria. The support plate 55 facilitates the removal of the thin mesh plate 52, providing tabletop isolation and support. Both sides of the bean sprout box 5 have perforated plates 58 corresponding to the upper sides of the filter paper 53 to enhance side ventilation. A labeling shell plate 59 is fixedly installed in the middle of the upper part of one side of the bean sprout box 5. The upper side of the labeling shell plate 59 is open, and a label card can be inserted into the inside of the labeling shell plate 59, displaying information about the bean variety.

[0031] Working principle and usage process of this utility model:

[0032] In use, sterile water is added to the inside of the water basin 1. Multiple bean sprout boxes 5 are placed on top of multiple sets of L-shaped placement rods 4. The experimental bean seeds are placed on top of the filter paper 53. Both ends of the water-absorbing ropes 57 inside the bean sprout boxes 5 are submerged in the sterile water in the water basin 1, allowing the water-absorbing ropes 57 to continuously absorb water. The lower side of the thin mesh plate 52 contacts the water-absorbing ropes 57. The thin mesh plate 52 can have coarse mesh openings, allowing the water on the water-absorbing ropes 57 to seep into the filter paper 53 on top of the thin mesh plate 52, thus continuously keeping the filter paper 53 moist without manual intervention. Replenishing the filter paper 53 with a spray bottle or dropper automatically keeps it continuously moist without causing significant fluctuations in its humidity level. This helps maintain relative stability in the filter paper 53's humidity, providing a stable and humid environment for soybean seed germination. Furthermore, the controller 3 can be set to repeatedly start the pump 9 at intervals. The pump 9 draws water from the water basin 1 through the suction pipe 10, then delivers it to the water guide rod 7 through the water delivery pipe 11, and finally sprays it downwards through the spray head 8. This allows for regular watering of the upper part of the soybean seeds, maintaining their moisture level. The upper surface of the seed is moist. Furthermore, handles 54 are fixedly installed on both sides of the upper side of the thin mesh plate 52. The thin mesh plate 52 is lifted using the handles 54 to quickly remove the soybean experimental seeds. Additionally, there are gaps between both ends of the support rod 51 and the inner wall of the bean sprout box 5. Support plates 55 are fixedly installed on both sides of the lower side of the thin mesh plate 52, and the support plates 55 are inserted into the gaps. Since soybean seeds need to be removed multiple times during germination and their data needs to be analyzed using equipment such as microscopes, directly removing the bean sprout box 5 is inconvenient. Removing the thin mesh plate 52 allows for connection to the filter... While removing the filter paper 53 together facilitates quick removal of the bean seeds, placing the thin mesh plate 52 directly on the table not only easily wets the table but also allows the underside of the filter paper 53 to come into contact with dust and bacteria. By setting up a support plate 55, the thin mesh plate 52 can be isolated and supported on the table when it is removed. In addition, a perforated plate 58 is set to enhance the side ventilation of the bean sprout box 5. Furthermore, an identification shell plate 59 is set, and an identification card can be inserted into the inside of the identification shell plate 59, which can display the bean seed information.
