Description

Technical Field

[0001] This invention belongs to the technical field of wheat breeding boxes, specifically referring to a wheat breeding box. Background Technology

[0002] As one of the world's major food crops, wheat breeding is a crucial link in ensuring food security and improving crop quality. Traditional seedling or breeding processes are usually carried out in petri dishes, seedling trays, or simple greenhouses, and the control of the cultivation environment mainly relies on manual operation and experience.

[0003] In existing technologies, the following shortcomings are commonly found when providing liquid culture (such as hydroponics or nutrient solution culture) for wheat seedlings: (1) Nutrient solution replenishment relies heavily on manual observation and timed and quantitative irrigation, which makes it difficult to respond to the plant’s consumption in real time and accurately. This can easily cause fluctuations in nutrient solution level or concentration, affecting the uniformity and stability of seedling growth. (2) During the standing process, the nutrients contained in the stored nutrient solution may be unevenly distributed due to sedimentation or stratification, making it difficult to ensure the consistency of nutrients supplied each time during irrigation. (3) For closed or semi-closed breeding boxes, the control of internal temperature and gas exchange often depends on fans, heating or cooling equipment powered by external power. This not only increases energy consumption and equipment complexity, but may also cause heat stress or poor ventilation to delicate breeding materials due to inaccurate control or malfunction, which is not conducive to creating a stable and energy-saving microenvironment.

[0004] Therefore, there is an urgent need for a wheat breeding device that can achieve precise irrigation of the culture medium by self-sensing, automatically maintain nutritional balance, and has intelligent and energy-saving temperature and gas regulation functions, so as to improve the automation level, environmental control accuracy and seedling quality of breeding experiments. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a wheat breeding box that creatively integrates three core functions: self-sensing irrigation, dynamic nutrient balancing, and passive temperature control and ventilation. Through infrared sensing and a floating mechanism, the liquid level is controlled in a closed loop to achieve precise and automatic supply of the nutrient solution. Irrigation water flows to drive a mechanical linkage device, simultaneously and continuously stirring the nutrient solution within the supply tank to ensure uniform nutrient distribution. Combined with the intelligent response of paraffin phase change materials, the temperature and ventilation within the breeding box are adaptively adjusted. All systems work collaboratively, providing a stable, balanced, and energy-efficient fully automated growth environment for wheat breeding without external electrical intervention, fundamentally improving the standardization and quality of seedling cultivation.

[0006] The technical solution adopted by this invention is as follows: This invention provides a wheat breeding box, including a breeding box, a self-induction triggered irrigation breeding device, an adaptive circulating ventilation device, and a water receiving tray.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Automatic sensing and precise irrigation of culture medium were achieved: Through the ingenious combination of floating plate, infrared transmitter and infrared receiver, a closed-loop feedback liquid level sensing system was constructed. The system can monitor the consumption of culture medium in the card frame plate in real time, and automatically start irrigation when the liquid level is lower than the set threshold and automatically stop when the liquid level recovers. It completely replaces manual observation and irrigation, realizes intelligent and precise management of water and nutrient supply in wheat breeding, and ensures the continuous stability of the seedling growth environment. 2. Ensures uniformity and consistency of nutrient supply: By setting up a mechanical linkage stirring mechanism consisting of a water wheel, bevel gear set and stirring rod in the water flow path, the flowing culture solution drives the water wheel to rotate while the irrigation pump is working, and automatically transfers the kinetic energy to the stirring device in the supply tank to continuously stir the stored culture solution. This design effectively prevents the sedimentation of solid particles in the nutrient solution or the layering of the solution, ensuring the balance of nutrient concentration output for each irrigation, and fundamentally improving the uniformity and reliability of seedling quality. 3. Passive and adaptive temperature and ventilation control is provided: Utilizing the characteristic of paraffin phase change material that undergoes significant volume change near a specific melting point, a purely mechanical temperature-responsive ventilation switch is designed by combining a piston rod, a return spring, and a control board. When the temperature inside the chamber reaches the melting point of paraffin, the ventilation opening automatically opens, and when the temperature drops, it automatically closes. This process requires no external power or control signal, making it energy-saving and environmentally friendly. At the same time, in conjunction with the bottom ventilation grid, natural convection is formed by utilizing the principle of rising hot air, which can effectively dissipate heat and exchange gases, precisely controlling the temperature inside the chamber to be close to the range suitable for wheat growth, creating a more stable and energy-saving breeding microclimate. 4. Improved spatial adaptability and ease of operation: The locking frame tray is movably connected to the supporting frame through the locking slide groove and is equipped with an adjustable movable adjustment ring, which allows the device to flexibly adapt to the height requirements of wheat at different growth stages, making it convenient to adjust the growth space and improving the utilization rate and applicability of a single set of equipment. The design of the overflow hole and water receiving tray can effectively collect and drain excess culture solution, keep the inside of the box clean, and avoid disease problems that may be caused by water accumulation.

The floating cavity 10 is located in the locking frame tray 9, and the liquid passage hole 11 is located on the side wall of the floating cavity 10. Floating grooves 13 are provided on the two opposite inner side walls of the floating cavity 10. The floating plate 12 is locked and slidably disposed in the floating grooves 13. An overflow hole 14 is provided at the upper end of the side wall of the locking frame tray 9 to allow excess culture medium 27 to flow out. The sensing and control component 8 includes an infrared transmitter 38, an infrared receiver 39, and a control box 40. The infrared transmitter 38 is located on the upper side wall of the locking frame tray 9, and the infrared receiver 39 is located on the upper side wall of the locking frame tray 9. The infrared transmitter 38 and the infrared receiver 39 are arranged opposite each other. The floating plate 12 is located between the infrared transmitter 38 and the infrared receiver 39. The control box 40 is located on the upper outer wall of the breeding box 1. The infrared transmitter 38, the infrared receiver 39, the control box 40, and the irrigation pump 26 are electrically connected.

[0026] In practical use, the wheat seeds to be bred are placed in the clamping frame tray 9, and the clamping frame tray 9 is slidably engaged with the supporting frame 19 via the clamping groove 21. Culture medium 27 is added to the clamping frame tray 9. At this time, the floating plate 12 floats up under the action of the culture medium 27, thus blocking the infrared rays emitted by the infrared transmitter 38. The infrared receiver 39 cannot receive the infrared signal, and the irrigation pump 26 does not work. As the culture medium 27 in the clamping frame tray 9 decreases, the floating plate 12 descends until it can no longer block the infrared rays emitted by the infrared transmitter 38, i.e., the infrared receiver 39 receives the infrared signal, and then controls... The irrigation pump 26 is started in tank 40. The irrigation pump 26 draws out the culture medium 27 from the supply tank 23 and transfers it to the supply pipe 24. The culture medium 27 is then transferred to the main pipe frame 15 and then to the irrigation branch pipe 17, which replenishes the culture medium 27 in the clamping frame plate 9. When the culture medium 27 passes through the opening 35, it drives the water wheel 28 to rotate. The rotation of the water wheel 28 drives the drive shaft 29 to rotate. The rotation of the drive shaft 29 drives the first bevel gear 31 to rotate. The rotation of the first bevel gear 31 drives the second bevel gear 32 to rotate. The rotation of the second bevel gear 32 drives the stirring rod 34 to rotate. The rotation of the stirring rod 34 drives the stirring support rod 37 to rotate. The culture solution 27 in the supply tank 23 is then stirred to further improve the nutritional balance during irrigation, thereby improving the quality of seedlings. As irrigation continues, the floating plate 12 rises continuously under the action of the culture solution 27 until it blocks the infrared rays emitted by the infrared transmitter 38, meaning the infrared receiver 39 can no longer receive the infrared signal. At this point, the control box 40 controls the irrigation pump 26 to stop working, and irrigation is complete. Excess culture solution 27 can flow out through the overflow hole 14 and fall into the water receiving tray 4 through the ventilation grid 42, achieving the technical effect of self-sensing uniform irrigation for wheat. When the temperature of the seedling box 1 is affected by... When the temperature rises to the melting point of paraffin wax 47 (paraffin wax 47 with a melting point close to that of wheat's suitable growth temperature can be selected) due to sunlight or its own respiration, the volume of paraffin wax 47 expands significantly, pushing the piston rod 46 outward, which in turn pushes the control plate 48 away from the vent 41, thereby opening the vent 41. After the temperature drops, the paraffin wax 47 solidifies and contracts, and the vent 41 closes under the action of the return spring 49. At the same time, in conjunction with the bottom ventilation grid 42, the natural convection circulation without a fan is formed by utilizing the principle of hot air rising, which precisely regulates the temperature and gas exchange in the breeding box 1. The above is the specific working process of this invention. This step can be repeated for the next use.
