Technical Field
[0001] This utility model relates to the field of breeding technology, specifically to a wheat seed cultivation device with a temperature self-regulation function. Background Technology
[0002] Wheat is a general term for plants of the genus Triticum, with common wheat being the representative species. It is a cereal crop widely cultivated around the world, belonging to the Poaceae family. Wheat caryopsis is one of the staple foods for humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles, and other foods. After fermentation, it can be used to make beer, alcohol, spirits (such as vodka), or biomass fuel. Wheat seed cultivation refers to cultivating wheat seeds to the germination stage. Wheat seed cultivation allows for the selection of wheat and the selection of high-quality seeds, which can increase the economic efficiency of wheat cultivation. In laboratories, wheat seed germination boxes are usually used to simulate the growth conditions of wheat seeds in the outdoor natural environment.
[0003] In the prior art, patent document CN218959434U discloses a seed germination box for wheat seed cultivation. During operation, an electric valve first opens, and a fan blows heat generated by an electric heating device into the germination box through an opening. When the temperature inside the germination box reaches the optimal temperature for wheat cultivation, the electric valve closes to prevent airflow between the outside and inside the germination box, which could lead to heat loss. Simultaneously, the electric valve opens again, and the fan blows air into the germination box for ventilation. Then, a spray nozzle sprays water into the germination box to replenish moisture during wheat seed cultivation, preventing dehydration due to high temperatures. Furthermore, a temperature sensor monitors the temperature inside the germination box, and supplemental lighting is provided to the wheat seeds. The structure is simple, the manufacturing cost is low, and it can easily reduce the cost of wheat seed cultivation in laboratories.
[0004] Patent document CN213755966U discloses a cultivation device for breeding high-quality wheat varieties. By setting up a control mechanism to control light intensity, it cultivates high-quality wheat varieties, reducing the labor intensity and workload of manual cultivation, facilitating its promotion and use, and simplifying equipment maintenance. The device also incorporates an adjustment mechanism to prevent diseases and pests in wheat seedlings, further reducing manual operation and ventilation, facilitating its widespread use, and enabling automatic control for easy equipment maintenance.
[0005] In the aforementioned prior art, it is inconvenient to observe the development of wheat seedlings after the wheat seeds germinate. The structures for auxiliary ventilation and temperature maintenance inside the cultivation device are independent of each other and have low integration. Therefore, the auxiliary ventilation and temperature maintenance structures occupy a large space. Utility Model Content
[0006] The main purpose of this invention is to provide a wheat seed cultivation device with a temperature self-regulating function that integrates auxiliary ventilation and temperature maintenance structures, reducing the overall volume of the cultivation device; at the same time, it facilitates the observation of wheat seedling development on the rear side of the cultivation device.
[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0008] A wheat seed cultivation device with self-regulating temperature function includes a box body. An inverted L-shaped vent is located at the top of the box body, connecting the interior of the box body to the outside. A door panel is hinged to the front of the box body. A rear cover is fixed to the rear of the box body, and an electric heating plate is fixed inside the rear cover. A gap is provided between the upper end of the electric heating plate and the upper end of the rear cover, and a gap is provided between the lower end of the electric heating plate and the lower end of the rear cover. A fan is installed at the rear of the rear cover, with the fan's outlet facing the electric heating plate. A vertical internal channel is provided in the rear side wall of the box body, communicating with the rear cover. Multiple outlets are provided vertically in the rear side wall of the box body. The outlet connects to the interior of the box and the inner channel. A connecting pipe is fixedly connected to the lower end of the rear cover. A solenoid valve is installed on the connecting pipe, which is connected to the humidifier. Multiple support units are set vertically inside the box. A light is installed above the support unit. A planting box is placed on the support unit. An irrigation unit is set inside the box above the planting box. A humidity sensor, a temperature sensor, and a gas content detection sensor are fixed inside the box. The fan, solenoid valve, heating plate, humidifier, temperature sensor, humidity sensor, gas content detection sensor, and controller are electrically connected.
[0009] Specifically, an inlet is provided on the rear side wall of the box, and the inlet connects the rear cover and the inner channel.
[0010] Specifically, a filter screen is fixed inside the air vent.
[0011] Specifically, the supporting unit includes a tray, the rear end of which is rotatably connected to the box. Multiple placement racks are fixed at the upper end of the tray. Each placement rack includes a fixed frame and a support frame. The fixed frame is located in front of the support frame, and the height of the support frame is greater than the height of the fixed frame. A stepped groove is provided at the upper end of the support frame. Planting boxes are placed in both the stepped groove and the fixed frame. A rotating rod is rotatably installed in the box below the tray. The rotating rod is located below the front end of the tray. A cam is fixed on the rotating rod, and the outer edge of the cam contacts the lower end of the tray. A motor corresponding to the rotating rod is fixed on the outside of the box. The output shaft of the motor is concentrically fixedly connected to the rotating rod. A switch is fixed on the outside of the box on one side of the motor. The switch, motor, and power supply are electrically connected.
[0012] Specifically, the motor is a brake motor.
[0013] Specifically, the irrigation unit includes a water pipe, which is fixed inside the box. The lower end of the water pipe is fixedly connected to a nozzle corresponding to the upper and lower parts of the planting box. The water pipe is connected to a water pump, the water pump is connected to a water tank, and the water pump is electrically connected to a controller.
[0014] Specifically, the gas content detection sensor is fixed in the middle of the box.
[0015] Specifically, the number of the carrying units is equal to the number of the outlets, and the outlets are located above one side of the carrying units.
[0016] Specifically, the light source is electrically connected to a time control switch fixed on the outside of the housing, and the light source, power supply, and time control switch are electrically connected.
[0017] Specifically, the door panel has a window, and tempered glass is fixedly and sealed inside the window.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. The device monitors the internal environment (including humidity, temperature, and oxygen / carbon dioxide levels) in real time using humidity, temperature, and gas content sensors. Combined with a controller, it automatically triggers humidification, heating, or ventilation. For example, it activates the humidifier and fan when humidity is insufficient; activates the heating plate when the temperature is too low; and performs ventilation when gas content is abnormal. These operations can be performed individually or in combination, ensuring the internal environment remains within preset threshold ranges (such as the optimal temperature and humidity range for wheat growth) without human intervention. This significantly improves environmental stability and reduces the risk of poor seed development due to fluctuations.
[0020] 2. The device integrates humidification, heating, and ventilation functions into one unit, with fans and heating plates working in tandem. This not only supports multiple operating modes, enhancing the adaptability and controllability of the cultivation process, but also strengthens the adjustability of the supporting unit, facilitating the observation of wheat plant development.
[0021] 3. The tempered glass window on the door panel provides a basic observation channel. The support unit uses a motor-driven cam to tilt the tray, allowing users to view the wheat plants inside the planting box from multiple angles (especially the growth of the plants at the back). This is particularly beneficial in the early stages of wheat growth, helping to detect developmental abnormalities early.
[0022] 4. The device employs intelligent control logic to reduce energy waste. Fans and heating plates operate only when needed, avoiding continuous power consumption; time-controlled switches precisely manage the sunlight cycle; this not only reduces operating costs but also improves equipment reliability and lifespan.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example 1: Refer to Figures 1-4 As shown, a wheat seed cultivation device with temperature self-regulation function includes a box 1. The upper end of the box 1 has an inverted L-shaped air hole 2, which connects the inside of the box 1 to the outside. A filter screen 3 is fixed inside the air hole 2.
[0030] The front end of the enclosure 1 is hinged to a door panel 4, and a window is provided on the door panel 4. Tempered glass is fixedly and sealed inside the window.
[0031] A rear cover 5 is fixed to the rear end of the housing 1. An electric heating plate 7 is fixed inside the rear cover 5. A gap is provided between the upper end of the electric heating plate 7 and the upper end of the rear cover 5, and a gap is provided between the lower end of the electric heating plate 7 and the lower end of the rear cover 5.
[0032] A fan 6 is installed at the rear end of the rear cover 5, and the air outlet of the fan 6 faces the heating plate 7.
[0033] A vertical inner channel 10 is provided in the rear side wall of the box 1. An inlet 26 is provided in the rear side wall of the box 1. The inlet 26 connects the rear cover 5 and the inner channel 10. Multiple outlets 11 are provided in the vertical direction of the rear side wall of the box 1. The outlets 11 connect the interior of the box 1 and the inner channel 10.
[0034] The lower end of the rear cover 5 is fixedly connected to a connecting pipe 8, and a solenoid valve 9 is installed on the connecting pipe 8. The connecting pipe 8 is connected to the humidifier.
[0035] Multiple support units are arranged vertically inside the housing 1. The number of support units is equal to the number of outlets 11. The outlets 11 are located above one side of the support units.
[0036] A light lamp 12 is installed above the support unit, and a planting box 20 is placed on the support unit.
[0037] An irrigation unit is installed inside the box 1 above the planting box 20.
[0038] The irrigation unit includes a water pipe 13, which is fixed inside the housing 1. The lower end of the water pipe 13 is fixedly connected to a nozzle 14 that corresponds to the upper and lower parts of the planting box 20. The water pipe 13 is connected to a water pump, the water pump is connected to a water tank, and the water pump is electrically connected to a controller.
[0039] A humidity sensor 21, a temperature sensor 22, and a gas content detection sensor 23 are fixed inside the housing 1. The gas content detection sensor 23 is fixed in the middle of the housing 1.
[0040] The fan 6, solenoid valve 9, heating plate 7, humidifier, temperature sensor 22, humidity sensor 21, gas content detection sensor 23, and controller are electrically connected.
[0041] The light lamp 12 is electrically connected to a time switch fixed on the outside of the housing 1, and the light lamp 12, the power supply and the time switch are electrically connected.
[0042] Place potting soil inside the planting box 20 and plant wheat seeds in the potting soil. Then place the planting box 20 on the support unit.
[0043] Humidity sensor 21 detects the air humidity inside chamber 1 in real time; temperature sensor 22 detects the temperature inside chamber 1 in real time; gas content sensor 23 detects the oxygen and carbon dioxide content in the air inside chamber 1 in real time.
[0044] When the air humidity inside chamber 1 falls below the minimum humidity threshold set in the controller, the controller activates solenoid valve 9, the humidifier, and fan 6. Fan 6 blows air into chamber 1 through rear cover 5, inlet 26, inner channel 10, and outlet 11. Water vapor generated by the humidifier enters rear cover 5 through connecting pipe 8 and flows into chamber 1 along with the air flowing through rear cover 5, thereby increasing the humidity inside chamber 1. This activates the humidification operation. When the air humidity inside chamber 1 reaches the humidity range set in the controller, the controller shuts off fan 6, humidifier, and solenoid valve 9.
[0045] When the temperature inside chamber 1 falls below the minimum temperature threshold set in the controller, the controller activates the heating plate 7. The air blown out by the fan 6 comes into contact with the heating plate 7 and its temperature rises. The heated air then enters chamber 1 and heats the interior of chamber 1. This operation is the heating operation. When the temperature inside chamber 1 reaches the temperature range set in the controller, the controller shuts off the fan 6 and the heating plate 7.
[0046] When the oxygen or carbon dioxide content in the air inside chamber 1 is high, the controller starts fan 6, which blows air into chamber 1. The air inside chamber 1 is then discharged to the outside through vent 2, thus preventing the oxygen or carbon dioxide content inside chamber 1 from becoming too high. This operation is a ventilation operation. When the oxygen and carbon dioxide content inside chamber 1 reaches the oxygen and carbon dioxide ranges set in the controller, respectively, the controller shuts off fan 6.
[0047] Humidification, heating, and ventilation can be performed individually or in combination depending on the environment inside chamber 1. This ensures that the environment inside chamber 1 is always conducive to wheat growth.
[0048] The duration of illumination for the wheat plants inside the box 1 can be adjusted by the time control switch.
[0049] Example 2: Based on Example 1, referring to... Figure 1 and Figure 3 As shown, the carrying unit includes a tray 15, the rear end of which is rotatably connected to the box 1, and multiple placement racks are fixed on the upper end of the tray 15.
[0050] The placement frame includes a fixed frame 18 and a support frame 19. The fixed frame 18 is located in front of the support frame 19. The height of the support frame 19 is greater than the height of the fixed frame 18. A stepped groove 25 is provided at the upper end of the support frame 19. Planting boxes 20 are placed in both the stepped groove 25 and the fixed frame 18.
[0051] A rotating rod 16 is rotatably installed inside the box 1 below the pallet 15. The rotating rod 16 is located below the front end of the pallet 15, and a cam 17 is fixed on the rotating rod 16. The outer edge of the cam 17 contacts the lower end of the pallet 15.
[0052] A motor 24 corresponding to the rotating rod 16 is fixed on the outside of the housing 1. The motor 24 is a brake motor. The output shaft of the motor 24 is concentrically fixedly connected to the rotating rod 16. A switch is fixed on the outside of the housing 1 on one side of the motor 24. The switch, the motor 24 and the power supply are electrically connected.
[0053] After installing planting boxes 20 in both the fixed frame 18 and the stepped groove 25, the height of the rear planting box 20 is greater than the height of the front planting box 20. This facilitates observation of the wheat plant development in the planting boxes 20 on both sides during the early stages of wheat growth.
[0054] The motor 24 is started by the switch. The motor 24 drives the rotating rod 16 and the cam 17 to rotate. During the rotation of the cam 17, the front end of the support plate 15 tilts downward, and the planting box 20 and the wheat plants inside it tilt, making it easier to observe the development of the wheat plants on the rear side of the planting box 20.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
