Description

Technical Field

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

[0002] Before sowing rice, the seeds need to be cultivated to germinate. During the germination process, it is necessary to ensure air permeability and a suitable temperature. At the same time, the seeds need to be soaked and watered regularly to ensure that they have enough moisture to germinate more easily.

[0003] However, existing rice seed germination devices have shortcomings in temperature control, making it difficult to maintain the "constant temperature and humidity" environment required for germination. They also lack active ventilation, relying solely on natural airflow through gaps, which can easily lead to localized oxygen deficiency due to seed respiration, affecting bud health and root development, and even causing "bud rot." Furthermore, traditional germination devices require frequent manual watering, making precise water control impossible, which is both labor-intensive and prone to human error affecting germination results. Utility Model Content

[0004] To overcome the problems of existing rice seed germination devices, such as difficulty in maintaining a constant temperature and humidity environment, lack of active ventilation leading to localized oxygen deficiency, and the need for frequent manual watering, this invention provides a seed germination device for rice cultivation. This device achieves a constant temperature and humidity environment through intelligent control, combined with active ventilation and uniform water replenishment, solving the problems of large temperature fluctuations, poor air permeability, and inaccurate water control in traditional devices. It achieves automatic regulation during the germination process, improving germination efficiency and quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A seed germination device for rice cultivation mainly includes a germination box, a support frame, a tray, a protective cover, a fan, an electric heating element, an exhaust pipe, a watering mechanism, a solar panel, a battery, and a controller. The germination box has a movable door at the front end and casters installed at the bottom, with brakes on the casters to fix the position of the germination box. The germination box has a hollow cavity structure, and temperature and humidity sensors are installed inside the cavity structure to monitor temperature and humidity changes in the germination box in real time. The support frame is installed vertically and at equal intervals inside the germination box, and the tray is horizontally overlapped on the support frame, with the side walls of the tray higher than the bottom plate, forming a shallow tray structure. Drainage holes are provided at the bottom of the tray to facilitate the drainage of excess water. An air inlet is provided on the side wall of the germination box, and the protective cover is installed on the outer side wall of the germination box and covers the air inlet. The fan and electric heating element are installed sequentially inside the protective cover, with the electric heating element near the air inlet for heating the air entering the germination box. An exhaust pipe is installed at the top of the germination chamber and connects to the interior to expel excess gas. A watering mechanism is installed at the end of the germination chamber, extending to the top and positioned directly above the uppermost tray, to evenly water the seeds. A controller is mounted on the side wall of the germination chamber, and the temperature sensor, humidity sensor, fan, heating element, and watering mechanism are all electrically connected to the controller. A solar panel is installed on one side of the germination chamber, and a battery is installed at the end of the solar panel. The battery is electrically connected via wires to the temperature sensor, humidity sensor, fan, heating element, watering mechanism, and controller, providing power to the entire system. The watering mechanism includes a water tank, a sealing cap, a level gauge, a water pump, an outlet pipe, a delivery pipe, a spray pipe, and nozzles. The water tank is installed at the end of the germination box, with a water inlet on the top and a sealing cap to prevent dust and other impurities from entering. The level gauge is installed outside the water tank to monitor the water level in real time. The water pump is installed on one side of the water tank, with one end of the outlet pipe connected to the water tank and the other end connected to the pump's inlet. The delivery pipe is installed on the side wall of the germination box, with its bottom connected to the pump's outlet and its top extending through the side wall into the interior. The spray pipe is installed on the top of the inner wall of the germination box, with its end connected to the delivery pipe. Nozzles are evenly spaced on the spray pipe, located directly above the tray, for uniformly spraying water onto the seeds. The water pump is electrically connected to a controller, which controls its start and stop based on feedback signals from a humidity sensor. The protective cover is equipped with a filter screen at the air inlet to filter the air entering the germination box and prevent dust and other impurities from affecting the seed germination effect. The filter screen is designed to be detachable for easy cleaning or replacement. The controller integrates a timing module for timed control of the fan, heating element, and water pump to meet the needs of seed germination at different stages. For example, during the seed water absorption stage, the controller can start the water pump to replenish water based on feedback signals from the humidity sensor; during the seed germination stage, the controller can adjust the operating status of the heating element and fan based on feedback signals from the temperature sensor to maintain a suitable temperature and humidity environment. The movable door is equipped with an anti-fog observation window, and the inner side is coated with a humidity compensation layer to prevent condensation from obstructing the view and to allow users to observe the inside of the germination box at any time. The controller is also electrically connected to an alarm module. When the level gauge detects that the water level in the tank is too low or the temperature / humidity sensor readings exceed the safe range, the alarm module is triggered to remind the user to handle the abnormal situation in a timely manner. The exhaust pipe has a bent structure with the opening facing downwards to prevent external dust from falling into the germination box and to prevent rainwater from flowing back in. The bend angle of the exhaust pipe ensures smooth exhaust while reducing external interference. The beneficial effects of this utility model are: The fan and electric heating element of this invention work together, combined with the intelligent control function of the controller, to maintain a constant temperature and humidity environment in the germination chamber. The filter on the protective cover effectively filters impurities in the air to prevent seed contamination. The watering mechanism provides even watering to the seeds through the nozzles, avoiding errors caused by manual intervention. The combination design of the solar panel and battery not only reduces energy consumption but also improves the environmental friendliness and sustainability of the device. In addition, the introduction of the alarm module further enhances the safety and reliability of the device, ensuring the stable operation of the germination process. Attached Figure Description

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0013] This utility model discloses a seed germination device for rice cultivation. The device mainly includes a germination box 1, a support frame 2, a tray 3, a protective cover 4, a fan 5, an electric heating element 6, an exhaust pipe 7, a watering mechanism 8, a solar panel 9, a battery 10, and a controller 11. The germination box 1 has a rectangular shape with a hinged door 12 at the front. The door 12 has an anti-fog observation window 29 embedded in it, with a humidity-compensating coating on the inside to prevent condensation from obstructing the view and allowing the user to easily observe the interior of the germination box 1. Four casters 13 are installed at the bottom of the germination box 1, evenly distributed at the four corners. Each caster 13 is equipped with a brake, which is manually operated to lock the germination box 1 in place.

[0014] The germination box 1 has a hollow internal structure. Multiple sets of support frames 2 are vertically and evenly spaced inside the cavity. The support frames 2 are fixed to the inner wall of the germination box 1 by welding or bolts. A tray 3 is horizontally attached to the support frames 2. The side walls of the tray 3 are higher than the bottom plate, forming a shallow tray structure. Multiple drainage holes with a diameter of 2-3 mm are evenly distributed at the bottom of the tray 3 to facilitate the drainage of excess water. An air inlet is located near the bottom of the side wall of the germination box 1. A protective cover 4 is installed outside the air inlet, fixed to the outer wall of the germination box 1 by bolts and completely covering the air inlet. Inside the protective cover 4, from the outside to the inside, a fan 5 and an electric heating element 6 are installed sequentially. The electric heating element 6 is located near the air inlet. The fan 5 is fixed to the inner wall of the protective cover 4 by a bracket, and the electric heating element 6 is fixed behind the fan 5, maintaining a certain distance between them to ensure smooth airflow. The exhaust pipe 7 is installed at the top center of the germination box 1. The exhaust pipe 7 has a bent pipe structure with the pipe opening facing downwards. One end of the exhaust pipe 7 is connected to the inside of the germination box 1, and the other end extends to the outside to discharge excess gas.

[0015] like Figure 3-5 As shown, the watering mechanism 8 is installed at the end of the germination box 1 and extends to the top of the germination box 1. The watering mechanism 8 includes a water tank 19, a sealing cover 20, a level gauge 21, a water pump 22, a water outlet pipe 23, a delivery pipe 24, a spray pipe 25, and a nozzle 26. The water tank 19 is fixed at the end of the germination box 1. A water inlet is provided at the top of the water tank 19, and a sealing cover 20 is connected to the water inlet. The level gauge 21 is fixed on the outside of the water tank 19 for real-time monitoring of the water level in the water tank 19. The water pump 22 is installed on one side of the water tank 19. One end of the water outlet pipe 23 is connected to the bottom of the water tank 19, and the other end is connected to the water inlet of the water pump 22. The delivery pipe 24 is fixed on the side wall of the germination box 1. The bottom of the delivery pipe 24 is connected to the water outlet of the water pump 22, and the top extends through the side wall of the germination box 1 into the interior and connects to the spray pipe 25. The spray pipe 25 is installed on the top of the inner wall of the germination box 1. The spray pipe 25 is located directly above the uppermost tray 3. The nozzles 26 are installed at equal intervals on the spray pipe 25 to ensure that the seeds on the tray 3 can be sprayed with water evenly.

[0016] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the solar panel 9 is fixed to one side of the germination box 1 by a bracket. The solar panel 9 is installed at an angle to maximize the reception of sunlight. The battery 10 is installed at the end of the solar panel 9. The battery 10 is electrically connected to the temperature sensor 15, humidity sensor 16, fan 5, electric heating element 6, water pump 22, and controller 11 via wires to provide power to the entire device. The controller 11 is fixed to the side wall of the germination box 1. The temperature sensor 15 and humidity sensor 16 are respectively installed on the inner side wall of the germination box 1 to monitor the temperature and humidity changes inside the germination box 1 in real time. The controller 11 integrates a timing module, which is connected to the fan 5, electric heating element 6, and water pump 22 via circuitry to perform timed control of the above components.

[0017] like Figure 4 , Figure 5 As shown, a filter 28 is installed at the air inlet of the protective cover 4. The filter 28 is fixed inside the protective cover 4 and is designed to be detachable for easy cleaning or replacement. The controller 11 is also electrically connected to an alarm module 30, which is fixed to the side wall of the controller 11. When the level gauge 21 detects that the water level in the water tank 19 is too low or the values ​​detected by the temperature sensor 15 and humidity sensor 16 exceed the safe range, the alarm module 30 is triggered and an alarm sound is emitted through a buzzer to remind the user to deal with the abnormal situation in time.

[0018] Rice seeds are placed in tray 3, the movable door 12 is closed, and the position of the germination box 1 is fixed by the braking device. After the device is started, the controller 11 controls the fan 5 and the electric heating tube 6 to work according to preset parameters. The fan 5 draws outside air into the protective cover 4. The air is filtered by the filter screen 28 and then enters the electric heating tube 6 for heating. The heated air enters the germination box 1 through the air inlet. The temperature sensor 15 monitors the temperature inside the germination box 1 in real time and feeds the data back to the controller 11. The controller 11 adjusts the heating power of the electric heating tube 6 according to the feedback signal to maintain a constant temperature. The humidity sensor 16 monitors the humidity inside the germination box 1 in real time and feeds the data back to the controller 11. When the humidity is lower than the set value, the controller 11 starts the water pump 22. The water pump 22 transports water from the water tank 19 to the delivery pipe 24 through the water outlet pipe 23, and then the delivery pipe 24 sends the water to the spray pipe 25. Finally, the seeds on the tray 3 are evenly sprayed with water through the nozzle 26. Excess water is discharged through the water-permeable holes at the bottom of the tray 3 to avoid water accumulation affecting seed growth. During the seed germination stage, the controller 11 periodically starts the fan 5 and the heating element 6 according to the set parameters of the timing module to ensure air circulation and stable temperature and humidity within the germination chamber 1. When the level gauge 21 detects that the water level in the water tank 19 is too low or the values ​​detected by the temperature sensor 15 and humidity sensor 16 exceed the safe range, the alarm module 30 is triggered and an alarm sound is emitted via a buzzer, reminding the user to replenish the water supply or adjust the parameters in a timely manner. The solar panel 9 converts solar energy into electrical energy and stores it in the battery 10, providing continuous and stable power support for the entire device.

[0019] Work process: First, rice seeds are evenly placed in tray 3 of germination chamber 1, ensuring a moderate seed layer thickness to avoid insufficient air permeability due to excessive accumulation. After closing the movable door 12, the position of germination chamber 1 is fixed by the braking device to ensure stability during operation. The user can observe the interior of germination chamber 1 at any time through the anti-fog observation window 29 to understand the germination status of the seeds. Subsequently, the controller 11 is activated, and the device enters the initial operation stage. The fan 5 starts working, drawing outside air into the protective cover 4. After being filtered by the filter screen 28, the air enters the heating area of ​​the electric heating tube 6. The electric heating tube 6 heats the air according to the preset temperature parameters of the controller 11. The heated air enters the interior of germination chamber 1 through the air inlet. The temperature sensor 15 monitors the temperature changes inside germination chamber 1 in real time and feeds the data back to the controller 11. If the temperature is lower than the set value, the controller 11 will increase the heating power of the heating element 6; if the temperature is too high, it will reduce the heating power or stop the operation of the heating element 6, effectively maintaining a suitable temperature environment in the germination chamber 1, thereby achieving constant temperature control and providing stable heat support for seed germination. The humidity sensor 16 monitors the humidity changes in the germination chamber 1 in real time. When the humidity is detected to be lower than the set value, the controller 11 starts the water pump 22. The water in the water tank 19 is transported to the delivery pipe 24 through the water outlet pipe 23, and then the delivery pipe 24 sends the water to the spray pipe 25. The spray nozzle 26 sprays water evenly on the seeds on the tray 3 to ensure that the seed surface is covered with an appropriate amount of water. Excess water is discharged through the water-permeable holes at the bottom of the tray 3 to avoid water accumulation and seed rot, reducing the need for manual intervention and improving the uniformity and efficiency of water replenishment.

[0020] During the seed germination stage, the controller 11 periodically starts the fan 5 and the electric heating tube 6 according to the set parameters of the timing module to ensure air circulation and stable temperature and humidity in the germination box 1. The fan 5 introduces fresh air into the germination box 1 through the air inlet, while the exhaust pipe 7 discharges excess gas, forming a good ventilation circulation system. This effectively avoids the local hypoxia problem caused by traditional devices relying solely on natural gap ventilation, and provides sufficient oxygen support for the growth of seedlings.

[0021] Furthermore, the solar panel 9 converts solar energy into electrical energy and stores it in the battery 10, providing continuous and stable power support for the entire device. This not only reduces the energy consumption cost of the device but also enhances its applicability in remote areas. When the level gauge 21 detects that the water level in the water tank 19 is too low or the temperature sensor 15 and humidity sensor 16 detect values ​​exceeding the safe range, the alarm module 30 is triggered and emits an alarm sound via a buzzer, reminding the user to handle the abnormal situation in a timely manner, thus improving the safety and reliability of the device.

[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
