Technical Field
[0001] This utility model relates to the field of soybean cultivation, and in particular to a soybean germination promoter. Background Technology
[0002] Soybeans are annual herbaceous plants belonging to the genus *Glycine* of the legume family. They are one of China's important food crops, rich in nutrients, and play a vital role in daily life and agricultural production. Soybean cultivation involves multiple stages, including soil preparation, seed treatment, sowing, and field management. Soybean germination devices, such as bean sprout machines or specialized germination equipment, are mainly used to promote the breaking of the seed coat, sprouting, and germination process of soybean seeds. These devices help soybean seeds germinate quickly and healthily by providing suitable temperature, humidity, and oxygen conditions.
[0003] Existing soybean germination machines typically use a fixed germination tray for placing soybean seeds. Due to differences in location, soybean seeds in different positions on the germination tray cannot receive water evenly from the spraying structure, which may lead to inconsistent germination. Furthermore, the spraying structure usually requires regular manual operation to spray water, which not only increases management costs and labor intensity, but also may cause soybean seeds to fail to germinate or grow slowly due to lack of water if the staff forgets to spray water.
[0004] Therefore, to address the problems of existing soybean germination machines where soybean seeds in different parts of the plant cannot receive water evenly and cannot be automatically sprayed regularly, a rotating placement component and a spraying component with a timer module for automatic water control can be designed. The rotation ensures that the soybean seeds receive water evenly, guaranteeing uniform moisture. The timer module allows for setting the spraying time, enabling the spraying component to spray water regularly according to the set schedule, controlling the spraying frequency, avoiding overwatering or forgetting to water, ensuring a suitable germination environment, achieving automation, reducing manual intervention, and improving work efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Soybeans are annual herbaceous plants belonging to the genus *Glycine* of the legume family. They are one of China's important food crops, a nutritious food crop that plays a vital role in daily life and agricultural production.
[0025] Plant characteristics: Soybeans grow to 30-90 cm tall, with stout and erect stems densely covered with long, stiff brown hairs. The leaves usually have 3 leaflets and are papery. The flowers are purple, light purple, or white. The pods are large, slightly curved, and drooping, densely covered with long, brownish-yellow hairs. There are 2-5 seeds, which are oval or nearly spherical, with smooth seed coats and various colors.
[0026] Origin and Uses: Soybeans originated in China and are cultivated throughout China and around the world. They are most commonly used to make various soy products, extract soybean oil, brew soy sauce, and extract protein.
[0027] Nutritional value: Soybeans are rich in protein, amino acids, lecithin, dietary fiber, and various antioxidants. They have many benefits, such as supplementing nutrition, strengthening the body, promoting bowel movements, regulating blood lipids and blood sugar, preventing osteoporosis, anti-oxidation, and delaying aging.
[0028] Soybean cultivation involves multiple stages, including soil preparation, seed treatment, sowing, and field management. Before sowing, soybeans are typically treated with a sprouting device to promote germination. Soybean sprouting devices, such as sprouting machines or specialized sprouting equipment, are mainly used to promote the breaking of the seed coat, the emergence of white hairs, and the germination process. These devices help soybean seeds germinate quickly and healthily by providing suitable temperature, humidity, and oxygen conditions. Sprouts grown using sprouting devices are usually more natural, organic, and non-toxic than commercially available sprouts. This is because sprouting devices eliminate the use of pesticides, fertilizers, and hormones, employing a completely natural cultivation method. For home users, using sprouting devices to grow soybeans not only provides healthy and safe sprouts but also offers the enjoyment of the planting process, helping to regulate emotions, especially during the pandemic, adding color to life.
[0029] Soybean sprouting devices have undergone a long history of development:
[0030] Early traditional stage
[0031] Natural germination: Initially, people mainly relied on the natural environment to germinate beans, such as placing beans in a warm and humid place and using the natural temperature and humidity to make them germinate. This method is simple, but it is greatly limited by natural conditions, and the germination rate and germination speed are difficult to control and are easily affected by the season and weather.
[0032] Simple sprouting tools: Later, some simple sprouting tools appeared, such as covering beans with a damp cloth or straw to maintain a certain level of humidity and promote sprouting. These methods improved the success rate of sprouting to some extent, but there were still problems such as inaccurate temperature and humidity control, which could easily lead to uneven sprouting.
[0033] Modern mechanical control stage
[0034] Constant temperature water bath germination device: With the development of technology, the constant temperature water bath germination device has emerged. Through a heating device and a temperature control system, it can provide a relatively stable water temperature environment for beans, allowing them to germinate faster at a suitable temperature. This type of germination device improves the speed and uniformity of germination, but its function is relatively limited, and it requires constant manual monitoring and adjustment of the water temperature.
[0035] Automatic spray germination device: To solve the problem of moisture control, an automatic spray germination device has emerged. It uses a timer and nozzles to spray water onto the beans at regular intervals and in measured quantities, maintaining the moisture level of the beans and further improving the germination effect. However, this type of device still has shortcomings in terms of temperature and ventilation control.
[0036] Modern intelligent stage
[0037] Microcomputer-controlled sprouters: Nowadays, microcomputer-controlled sprouters have become the mainstream. They integrate multiple sensors such as temperature, humidity, and ventilation, enabling precise control of various parameters of the sprouting environment and realizing an intelligent sprouting process. Users only need to set the corresponding parameters, and the sprouter can run automatically, providing the best sprouting conditions for beans and greatly improving the germination rate and quality.
[0038] Multifunctional integrated sprouting machine: In addition to the basic sprouting function, modern sprouting machines have more functions, such as sterilization and light adjustment. Some sprouting machines can also provide personalized sprouting programs according to the characteristics of different beans, meeting the diverse needs of users. In addition, the design of sprouting machines is more user-friendly, easier to operate, and more aesthetically pleasing.
[0039] Future development trends
[0040] Energy-saving and environmentally friendly: Future bean sprouting machines will pay more attention to energy conservation and environmental protection, adopting efficient heating, cooling and ventilation technologies to reduce energy consumption and minimize environmental impact.
[0041] Remote monitoring and automation: With the help of Internet of Things (IoT) technology, the germination machine will be remotely monitored and automated. Users can remotely control the operation status of the germination machine and view the germination data in real time through mobile phones or computers, thus realizing intelligent agricultural production.
[0042] Personalized Customization: As people's demands for the quality and taste of beans continue to increase, sprouting machines will develop towards personalized customization. Based on the needs of different bean varieties and different growth stages, more precise and personalized sprouting solutions will be provided to meet users' specific requirements.
[0043] The development history of soybean sprouting equipment reflects the evolution from traditional methods to specialized sprouting machines, and then to new sprouting devices, continuously improving the yield, quality, and production efficiency of soybean sprouts. However, soybean sprouting equipment often encounters some problems during actual use. Below are some common problems and their possible causes: 1. Failure to sprout: The main causes may be poor seed quality or excessively low temperature. 2. Rotten sprouts: The main causes may be poor seed quality, unclean sprouting machine, excessively low or unstable temperature, or unclean water. 3. Uneven sprout growth: The main causes may be poor seed quality or insufficient compaction of the water tank. 4. Weak sprouts: The main causes may be late harvesting or failure to compact the water tank. 5. Discoloration of sprouts: The main causes may be exposure to light or excessively high temperature.
[0044] Currently, various soybean sprouting machines are available on the market, but some problems and challenges still exist in actual use. For example: 1. Multifunctional intelligent bean sprout machines: These work by automatically watering and pressurizing to provide a suitable growing environment for bean sprouts. However, problems such as non-germination, rotten sprouts, uneven growth, weak sprouts, and discoloration may occur. These issues involve factors such as seed quality, temperature control, water quality, and machine cleanliness. 2. Automatic multifunctional bean sprout machines: These use water circulation and microcomputer intelligent timing technologies to automatically cultivate bean sprouts. Problems are similar to those of multifunctional intelligent bean sprout machines, including poor germination and rotting sprouts. Careful use and maintenance are necessary. 3. Other types: These include cross-border bean sprout machines and clearance sale bean sprout machines. Their working principle is similar to the above two types, but they may differ in brand, price, and functions. The problems also require careful attention to seed selection, temperature control, and machine cleanliness to avoid poor germination.
[0045] Please see Figures 1-2 This utility model provides an embodiment: a soybean germination device, including a box body 1, a placement component, a spraying component, an air supply component, a box door 5, and a transparent glass 6. The inside of the box body 1 is symmetrically fixedly installed with two sets of placement components for placing soybean seeds and driving the soybean seeds to rotate.

The drive motor 207 drives the rotating shaft 206 to rotate. The drive motor 207 is fixedly installed at the lower end of the partition 201. The drive motor 207 drives the rotating shaft 206 to rotate, which in turn drives the turntable 202 to rotate synchronously. The interior of the turntable 202 is evenly distributed with six sets of placement trays 203 for placing culture medium and soybean seeds. The lower end of the placement tray 203 is fixedly connected to the bottom of the turntable 202 through the support column 204. The bottom of the placement tray 203 is evenly distributed with ventilation holes 205 to increase air permeability and prevent the seeds from being soaked in water. The upper middle part of the partition 201 is symmetrically opened with through holes 208 to increase air circulation.
[0047] Please see Figure 5 In this embodiment, the spraying assembly includes a water tank 301, an inlet pipe 302, nozzles 303, a hydraulic controller 304, a timer 305, and a control module 306. The upper end of the water tank 301 is fixedly equipped with an inlet pipe 302 for introducing water. A control valve for controlling the inflow and outflow of water is provided on the outer side of the inlet pipe 302. Two sets of nozzles 303, matching the placement assembly, are symmetrically fixedly installed at one end of the water tank 301 near the housing 1. The nozzles 303 extend from the outer side to the inner side of the housing 1. A hydraulic controller 304 for controlling water pressure is fixedly installed at the center of the front end of the water tank 301. The hydraulic controller 304 is of model LY. 810. A timer 305 for setting the water spraying time is fixedly installed at the front end of the water tank 301 above the hydraulic controller 304. The timer 305 is model FC5A-F2M2. The timer 305 is electrically connected to the hydraulic controller 304 via a connecting wire. The timer 305 has a control module inside for controlling the operation of the hydraulic controller 304. A heating coil for heating is fixedly installed inside the water tank 301. One end of the heating coil extends through the water tank 301 to the outside and is fixedly connected to a control module 306 for controlling the heating temperature and working status of the heating coil. The control module 306 is model MK-C315.
[0048] Please see Figure 6In this embodiment, the gas delivery assembly includes an oxygen storage tank 401, an air inlet pipe 402, a fan 403, and a duct pipe 404. An air inlet pipe 402 for introducing oxygen is fixedly installed in the middle of the upper end of the oxygen storage tank 401. A fan 403 for blowing oxygen into the tank 1 is embedded in the middle of the end of the oxygen storage tank 401 near the tank body 1. A duct pipe 404 for introducing oxygen into the tank 1 is fixedly connected to the end of the fan 403 near the tank body 1. The duct pipe 404 extends through the rear end of the tank body 1 to its inner side. A control valve for controlling the inlet and outlet is provided on the outer side of the connection between the air inlet pipe 402 and the oxygen storage tank 401.
[0049] When working, first move box 1 to the corresponding stable position and place it;
[0050] Then open the box door 5, put the culture medium required for soybean seed germination into the corresponding placement tray 203, sprinkle the soybean seeds that need to be germinated onto the culture medium, and cover the surface of the soybean seeds with a small amount of culture medium again.
[0051] Then close the box door 5, spray an appropriate amount of water onto the soybean seeds in the placement tray 203 through the spraying assembly, introduce water into the water tank 301 through the water inlet pipe 302, and adjust the water pressure to a suitable level through the hydraulic controller 304 so that the nozzle 303 sprays water onto the soybean seeds in the placement tray 203.
[0052] During the spraying process of the spraying component, the drive motor 207 drives the rotating shaft 206 to rotate the turntable 202, so that the placement tray 203 in the turntable 202 rotates synchronously with the turntable 202, thereby allowing the soybean seeds in different placement trays 203 to receive the water sprayed by the spraying component evenly through rotation.
[0053] Depending on the different germination requirements and the actual situation of soybean germination, the heating coil in the water tank 301 can be controlled by the control module 306 to appropriately heat the water to promote soybean germination.
[0054] During the soybean germination process, an appropriate amount of oxygen is introduced into the box 1 through the air supply component, and the oxygen is introduced into the oxygen storage box 401 through the air inlet pipe 402. Then, the oxygen is introduced into the box 1 through the air guide pipe 404 by the fan 403. The air circulation in the box 1 is maintained through the ventilation groove 7 at the top of the box 1. At the same time, the germination of soybeans can be observed through the transparent glass 6 on the box door 5 during the germination process.
[0055] Finally, the spraying interval is set by the timer 305 on the spraying assembly, so that the timer 305 periodically controls the hydraulic controller 304 to adjust the water pressure to spray water in order to maintain the moisture required for soybean germination.
[0056] Through the above steps, by setting a rotatable placement component on the placement tray 203 and a spraying component with a timer module for automatic water control, the soybean seeds can receive water evenly through rotation, ensuring uniform moisture and consistent germination. The timer module allows the spraying component to spray water periodically according to the set time, controlling the watering frequency and preventing over-watering or forgetting to water, thus ensuring a suitable germination environment. This automation reduces manual intervention and improves work efficiency. It addresses the problem that existing soybean germination machines typically use a fixed germination tray, where soybean seeds at different positions on the tray do not receive water evenly due to positional differences, leading to inconsistent germination. Furthermore, the spraying mechanism usually requires regular manual operation, increasing management costs and labor intensity. If workers forget to spray water, soybean seeds may fail to germinate due to lack of water or experience slow growth.
