Description

Technical Field

[0001] This utility model relates to the field of soybean planting technology, and in particular to a soybean germination device. Background Technology

[0002] Soybeans are an important food and economic crop in my country. The germination process directly affects the germination rate, emergence rate, and subsequent seedling growth of soybeans, thus influencing the final yield and quality. A good germination environment requires precise control of temperature, humidity, and gas composition to ensure that soybean seeds germinate quickly and uniformly under suitable conditions.

[0003] Currently, most existing soybean germination devices are of an integrated structure, making it difficult to achieve independent control of multiple germination zones. When different batches and varieties of soybean seeds need to be germinated simultaneously, the environmental parameters of each zone cannot be flexibly adjusted according to the characteristics of the seeds, resulting in inconsistent germination effects. At the same time, most devices lack monitoring and control of carbon dioxide concentration. During the germination process of soybean seeds, respiration produces a large amount of carbon dioxide. If the carbon dioxide concentration is too high, it will inhibit seed respiration, leading to seed hypoxia and necrosis, and affecting the germination rate.

[0004] Therefore, based on the shortcomings of the existing technology, developing a soybean planting and germination device that can achieve independent control of multiple regions, precise control of environmental parameters, and convenient operation has important practical value. Utility Model Content

[0005] The main purpose of this invention is to provide a soybean planting and germination device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides a soybean germination device, comprising a germination box, a fan, an atomizing humidifier, and a controller. The germination box is divided into multiple germination chambers by partitions; each germination chamber contains a soybean seedling tray; each germination chamber is equipped with a temperature sensor, a humidity sensor, and a carbon dioxide sensor; the fan outlet is connected to a main ventilation pipe, which is connected to multiple branch ventilation pipes via multiple distribution valves, each branch ventilation pipe corresponding to one germination chamber; each branch ventilation pipe is equipped with a heating wire; the atomizing humidifier is connected to multiple germination chambers via multiple flexible hoses; each flexible hose is equipped with a solenoid valve; each germination chamber has an air outlet on one side; the fan, atomizing humidifier, temperature sensor, humidity sensor, carbon dioxide sensor, heating wire, and solenoid valve are all electrically connected to the controller.

[0007] Furthermore, the controller is installed on the top or side of the germination box.

[0008] Furthermore, it also includes a storage box, on which the germination box is installed.

[0009] Furthermore, the fan and atomizing humidifier are installed on one side of the germination box or inside the storage box.

[0010] Furthermore, the carbon dioxide sensor is positioned close to the air outlet and higher than the soybean seedling tray.

[0011] Furthermore, the inner wall of the germination chamber is provided with a heat insulation layer.

[0012] Furthermore, the germination box is provided with a door on the front side, and an insulation layer is provided on the inside of the door.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model divides the germination box into multiple germination chambers by partitions, and with independent ventilation branches, heating wires, hoses and solenoid valves, it can achieve independent control of multiple germination chambers. It can process different batches and varieties of soybean seeds at the same time. The temperature, humidity and ventilation of each chamber can be flexibly adjusted according to the characteristics of the seeds, which solves the problem of inconvenient multi-area control of existing devices and improves the flexibility and targeting of germination.

[0015] 2. Each germination chamber is equipped with three sensors: temperature, humidity, and carbon dioxide. These sensors can comprehensively and in real time monitor the germination environment parameters. The controller automatically adjusts each component based on the monitoring data to achieve precise control of the environmental parameters. This avoids the adverse effects of temperature and humidity fluctuations and excessively high carbon dioxide concentrations on germination, effectively improving the soybean germination rate and quality.

[0016] 3. The carbon dioxide sensor is installed close to the air outlet and higher than the soybean seedling tray, which makes the monitoring data more accurate and can capture changes in carbon dioxide concentration in the germination chamber in a timely manner. Excess carbon dioxide is quickly discharged through the air circulation of the fan and air outlet, ensuring the oxygen required for seed respiration and reducing the probability of seed hypoxia and necrosis.

Detailed Implementation

[0019] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0020] like Figure 1 As shown, this utility model provides a soybean germination device, including a germination box 2, a fan 13, a misting humidifier 12, and a controller 1. The germination box 2 is divided into four germination chambers 3 by three partitions 5. The setting of multiple germination chambers 3 can realize the simultaneous germination of soybean seeds of different batches and varieties, and can independently control the environment of each chamber without interference. Each germination chamber 3 is equipped with a soybean seedling tray 4, which is used to hold soybean seeds, making it convenient for the seeds to be placed, observed, and removed. The appropriate size of the seedling tray can be selected according to the germination requirements.

[0021] A temperature sensor 15, a humidity sensor 16, and a carbon dioxide sensor 17 are fixedly installed inside the germination chamber 3. The three sensors work together to monitor the core environmental parameters inside the germination chamber 3 in real time: the temperature sensor 15 monitors the temperature inside the germination chamber 3 to ensure that the temperature is within the suitable range for soybean germination; the humidity sensor 16 monitors the air humidity inside the germination chamber 3 to prevent excessive humidity from causing seed mold and excessively low humidity from affecting seed water absorption and germination; the carbon dioxide sensor 17 monitors the carbon dioxide concentration inside the germination chamber 3 to prevent excessive concentration from inhibiting seed respiration. The carbon dioxide sensor 17 is located near the air outlet 18 and above the soybean seedling tray 4. This installation position allows for more accurate capture of the carbon dioxide concentration at the end of the gas flow inside the germination chamber 3, ensuring the accuracy of the monitoring data.

[0022] The fan 13 provides fresh air to the germination chamber 3 to ensure the oxygen required for seed respiration. The air outlet of the fan 13 is connected to the main ventilation pipe 10, which is connected to three ventilation branch pipes 8 through three distribution valves 9. Each ventilation branch pipe 8 is connected to a germination chamber 3. The ventilation volume of each ventilation branch pipe 8 can be independently controlled through the distribution valves 9, so as to realize the flexible adjustment of the ventilation volume of each germination chamber 3. Each ventilation branch pipe 8 is equipped with a heating wire 11. The heating wire 11 can heat the air entering the germination chamber 3. With the help of the temperature sensor 15, the temperature inside the germination chamber can be accurately controlled. When the temperature inside the germination chamber is lower than the set threshold, the heating wire starts heating and heats the air to a suitable temperature before sending it into the germination chamber to ensure stable germination temperature.

[0023] The atomizing humidifier 12 is used to provide moisture to the germination chamber 3 and regulate the air humidity inside the germination chamber 3. The atomizing humidifier 12 is connected to the four germination chambers 3 through four hoses 7, and each hose 7 is equipped with a solenoid valve 6. The solenoid valve 6 can control the opening and closing of each hose 7 to achieve independent control of the humidity of each germination chamber 3. Based on the humidity monitoring data in different germination chambers, moisture is accurately replenished. Each germination chamber 3 has an air outlet 18 on one side. The air outlet 18 is used to exhaust the polluted air (containing excessive carbon dioxide, water vapor, etc.) in the germination chamber 3. Together with the fan 13, the main ventilation pipe 10, and the branch ventilation pipe 8, it forms a complete air circulation system to ensure air circulation in the germination chamber 3.

[0024] The fan 13, atomizing humidifier 12, temperature sensor 15, humidity sensor 16, carbon dioxide sensor 17, heating wire 11, and solenoid valve 6 are all electrically connected to the controller 1. The controller 1, as the control core of the entire device, receives monitoring data transmitted from each sensor and automatically controls the start / stop and operating status of each actuator according to preset environmental parameter thresholds, achieving automated and precise control of the germination environment. Simultaneously, the controller 1 allows manual adjustment of various parameters to meet different germination needs.

[0025] In this embodiment, the controller 1 is installed on the top or side of the germination box 2 for easy observation and operation by the operator; the device also includes a storage box 14, on which the germination box 2 is fixedly installed. The storage box 14 is used to store soybean seeds, seedling trays and maintenance tools; the fan 13 and the atomizing humidifier 12 are installed on one side of the germination box 2, or can be placed inside the storage box 14 to save space and provide protection; the inner wall of the germination chamber 3 is covered with a heat insulation layer made of heat insulation cotton, and a door is provided on the front side of the germination box 2. The inside of the door is also covered with heat insulation cotton to enhance the heat insulation effect.

[0026] The working process of this embodiment is as follows: Before use, the operator opens the door of the germination box 2, places the selected soybean seeds of different batches or varieties into the soybean seedling trays 4 of each germination chamber 3, and closes the door; the appropriate germination parameters of each germination chamber 3 are preset by the controller 1.

[0027] The start-up device uses temperature sensor 15, humidity sensor 16, and carbon dioxide sensor 17 to monitor the environmental parameters inside each germination chamber 3 in real time and transmit the monitoring data to controller 1. When the temperature inside a germination chamber 3 is lower than a preset threshold, controller 1 controls the heating wire 11 in the ventilation branch pipe 8 corresponding to that germination chamber 3 to start, and simultaneously starts the fan 13. Fresh outside air is sent into the germination chamber 3 through the main ventilation pipe 10, distribution valve 9, and ventilation branch pipe 8 (heated by the heating wire 11) until the temperature reaches the preset threshold, at which point the heating wire 11 stops working. When the temperature is higher than the preset threshold, the fan 13 continues to blow air, and hot air is discharged through the air outlet 18 to reduce the temperature inside the chamber.

[0028] When the humidity in a certain germination chamber 3 is lower than the preset threshold, the controller 1 controls the solenoid valve 6 on the hose 7 corresponding to the germination chamber 3 to open, and the atomizing humidifier 12 starts to send water mist into the germination chamber 3 through the hose 7 until the humidity reaches the preset threshold, the solenoid valve 6 closes, and the atomizing humidifier 12 stops working; when the humidity is too high, the controller 1 controls the fan 13 to increase the ventilation volume and discharge excess water vapor through the air outlet 18.

[0029] When the carbon dioxide concentration in a certain germination chamber 3 is higher than the preset threshold, the controller 1 controls the fan 13 to increase the ventilation volume corresponding to the germination chamber 3, discharges the excess carbon dioxide through the air outlet 18, and introduces fresh air until the carbon dioxide concentration drops to the preset threshold.

[0030] During the germination process, operators can observe the germination status of soybean seeds in each germination chamber 3 through the door. If parameters need to be adjusted, they can be manually adjusted through the controller 1. The storage box 14 allows for easy access to seeds and tools, facilitating maintenance. After germination is complete, the device is turned off, the door is opened, and the soybean seedling tray 4 is removed to obtain the germinated soybean seeds.

Anyone should know that structural changes made under the guidance of the present utility model are protected by the present utility model. All technical solutions that are the same as or similar to the present utility model are within the scope of protection of the present utility model.
