Description

Technical Field

[0001] This invention belongs to the field of seed cultivation technology, and in particular relates to a seed growth characteristic control cultivation device. Background Technology

[0002] In agricultural research and breeding, the study of seed growth characteristics is a core foundation for improving crop yield and optimizing planting programs. Key characteristics such as seed germination rate, growth rate, and stress resistance are all closely related to the growth environment. Therefore, it is necessary to conduct controlled cultivation experiments to accurately analyze the effects of environmental factors such as temperature, humidity, light, and nutrient solution on seed growth. As the core equipment for conducting such experiments, the performance of the controlled cultivation device directly determines the accuracy, reliability, and efficiency of the experimental data. Summary of the Invention

[0003] The purpose of this invention is to address the problem that existing seed cultivation devices are mainly divided into two categories: single-environment incubators and simple multi-zone cultivation racks. While single-environment incubators can achieve basic control of environmental parameters such as temperature and humidity, they only provide a single growth environment. If multiple control experiments are required, multiple incubators need to be purchased, resulting in high equipment purchase and maintenance costs, significant laboratory space consumption, and potential discrepancies in basic environmental parameters between different incubators. This reduces the comparability of control experiment data and affects the scientific validity of the experimental results.

[0004] This invention achieves the above objectives through the following technical solution: a seed growth characteristic control cultivation device, comprising a support frame, on which at least two independent seed cultivation units are spaced apart to achieve control cultivation of seed growth characteristics, namely a first seed cultivation device, a second seed cultivation device, and a third seed cultivation device. The first seed cultivation device includes a heat-insulating support device, on which several ventilation fans are arranged on both sides, and a movable spray device is provided at the upper end of the heat-insulating support device. A seed cultivation tray is disposed inside the heat-insulating support device, and an atomizing device is arranged around the inner side wall of the heat-insulating support device. A lifting and adjusting door is provided on one side of the heat-insulating support device. By setting at least two independent seed cultivation units on the support frame, a basic structural support is provided for the control experiment of seed growth characteristics, and multiple groups of seed cultivation can be carried out simultaneously. Each cultivation unit integrates functional components such as ventilation fans, movable spray devices, and atomizing devices, which can provide a basic ventilation, water supply, and humidification environment for seed growth. The overall structure is compact and functionally complete, facilitating the operation and management of subsequent control experiments.

[0005] Furthermore, the heat-insulating support device includes an insulated box, inside which a heating pipe and a cooling fan are installed. The insulated box has a ventilation fan mounting hole corresponding to the installation position of the ventilation fan. The insulated box also has a drain outlet. The atomizing device includes an atomizing connecting pipe and several atomizing nozzles arranged on the atomizing connecting pipe. The atomizing connecting pipe is located inside the insulated box. The combination of the heating pipe and the cooling fan in the heat-insulating support device allows for flexible temperature adjustment within the cultivation unit, adapting to the temperature requirements of different seed growth stages. The design of the atomizing connecting pipe and atomizing nozzles allows water mist to diffuse more evenly within the cultivation unit, improving the uniformity of humidity control. The configuration of the ventilation fan mounting hole and the drain outlet ensures air circulation within the unit while preventing water accumulation, further enhancing the environmental control capability and ease of use of the insulated box.

[0006] Furthermore, the mobile spraying device includes a crossbeam, on which a connecting pipe and spray nozzles are arranged. The mobile spraying device also includes a drive assembly for driving its movement. The drive assembly includes a fixed plate connected to the crossbeam and a first rotating motor mounted on the fixed plate. The output end of the first rotating motor is connected to a rotating gear, which meshes with a rack disposed on the heat-insulating support device. The drive assembly controls the forward and reverse rotation of the first rotating motor to drive the rotating gear to reciprocate along the rack, thereby driving the mobile spraying device to reciprocate within the heat-insulating support device along the extension direction corresponding to the crossbeam. The reciprocating movement of the mobile spraying device through the drive assembly can drive the spray nozzles to evenly cover the seed area within the cultivation unit, avoiding the problem of uneven watering in certain areas. The meshing structure of the rotating gear and the rack is stable and the transmission is reliable, ensuring the smoothness of the spraying device's movement, effectively improving the uniformity of water supply and the automation level of the spraying operation, and reducing errors from manual watering.

[0007] Furthermore, the seed cultivation tray includes a seed germination tray and a nutrient solution carrying tray disposed below the seed germination tray. The seed germination tray and the nutrient solution carrying tray are spaced apart by raised blocks, and the seed germination tray has multiple root growth holes for the seed roots to pass through. The nutrient solution carrying tray is equipped with a nutrient solution adding pump, a nutrient solution extracting pump, and a nutrient solution level sensor for detecting the nutrient solution level. The nutrient solution level sensor is electrically connected to the adding pump and the extracting pump, respectively. When the nutrient solution level in the nutrient solution carrying tray is detected by the nutrient solution level sensor as being lower than a preset lower threshold, the adding pump is triggered to start and replenish the nutrient solution in the nutrient solution carrying tray. When the nutrient solution level sensor detects that the nutrient solution level is higher than a preset upper limit threshold or that the solution needs to be replaced, it triggers the pump to start and drain excess nutrient solution from the nutrient solution carrying tray, thus achieving automatic circulation and regulation of the nutrient solution. The root growth holes of the seed germination tray provide extension space for seed root growth. Combined with the spaced design of the raised blocks, this allows the roots to contact the nutrient solution while preventing the seeds from rotting from being soaked in water. The linkage control of the level sensor with the adding and draining pumps achieves automatic circulation and precise level regulation of the nutrient solution, eliminating the need for frequent manual operation. This reduces labor costs and avoids problems of insufficient or excessive nutrient solution, ensuring the healthy growth of the seed roots.

[0008] Furthermore, the lifting and adjusting door includes a lifting door and a second rotary motor for driving the lifting door to rise and fall. The second rotary motor is disposed on the side wall of the heat-insulating support device. The second rotary motor is connected to the lifting door through a transmission structure to drive the lifting door to move up and down along the side wall of the heat-insulating support device, thereby adjusting the rise and fall of the air and temperature inside the heat-insulating support device. The automatic rise and fall of the lifting door driven by the second rotary motor is labor-saving and has higher adjustment accuracy. The internal space height of the heat-insulating support device can be flexibly changed, thereby adjusting the air circulation efficiency and temperature distribution within the unit, adapting to the different spatial and environmental needs of seeds from germination to seedling stages, and improving the adaptability of the device to the entire seed growth cycle.

[0009] Furthermore, the lighting system includes a lampshade with a fan mounted on top. At least one light source rod is arranged inside the lampshade. The lampshade is independently positioned above each seed cultivation unit. The light source rod provides growth illumination to the seed cultivation units below. Each cultivation unit has an independent lighting system, enabling independent control of light conditions for different units and providing support for light variables in control experiments. The combination of the fan and the lampshade effectively dissipates heat from the light source, ensuring its stability and lifespan, while also providing illumination to the cultivation units below, thus balancing light supply and equipment reliability.

[0010] Furthermore, the light source rod is an LED light source rod with adjustable spectrum and brightness. The fan works in conjunction with the heat dissipation structure inside the lighting cover to dissipate the heat generated by the light source rod during operation, preventing overheating of the light source from affecting the stability of the lighting. At the same time, it delivers warm air downwards. The LED light source rod with adjustable spectrum and brightness can match the light requirements of different seed growth stages (such as germination and leaf expansion), improving the adaptability of light to seed growth. The fan not only solves the problem of heat dissipation of the light source, but also delivers warm air downwards to help regulate the temperature within the cultivation unit, achieving coordinated control of light and temperature, and further optimizing the seed growth environment.

[0011] Furthermore, the operating parameters of the lighting system, heating tube, cooling fan, and atomizing device of each seed cultivation unit can be set independently to create differentiated temperature, humidity, and light conditions in different seed cultivation units, meeting the needs of control experiments on multiple groups of seed growth characteristics. The temperature, humidity, and light parameters of each cultivation unit can be set independently, enabling the construction of multiple differentiated growth environments within the same device, meeting the needs of multivariate and multi-group seed growth characteristic control experiments. By controlling single variables or combinations of multiple variables, the influence of different environmental factors on seed growth can be analyzed more accurately, improving the comprehensiveness of control experiments and the reference value of data.

[0012] Furthermore, a transparent sealing plate is provided around the outer edge of the support frame for heat preservation and observation of seed development. A heat-insulating layer is fitted to the inner wall of the heat-insulating box, and sealing strips are provided at the mating edges of the heat-insulating box and the lifting door to enhance the sealing and heat preservation performance of the heat-insulating support device. The transparent sealing plate on the outer side of the support frame ensures heat preservation while allowing direct observation of seed growth without frequent opening of the device, reducing interference from the external environment on the cultivation unit. The heat insulation layer and sealing strips of the heat-insulating box further enhance the sealing and heat preservation performance of the unit, reducing the impact of external environmental fluctuations on internal cultivation conditions and improving the stability of the control experiment environment and the accuracy of the data.

[0013] Furthermore, this device can automatically and precisely control environmental factors such as temperature, humidity, light, and nutrient solution in each cultivation unit to meet the control cultivation needs of multiple groups of seeds to measure their growth characteristics.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Parallel control cultivation of multiple seed growth characteristics: The device design includes at least two independent seed cultivation units (e.g., the first, second, and third seed cultivation devices), and allows independent setting of parameters such as temperature, humidity, light, and nutrient solution for each unit. This enables researchers to conduct multiple control experiments simultaneously within the same device. By controlling one or more variables, researchers can accurately analyze the effects of different environmental factors on seed growth, significantly improving experimental efficiency and the scientific reliability and reference value of comparative data. 2. Automated, precise, and independent control of environmental factors: The device integrates heating tubes, cooling fans, ventilation fans, atomizing devices, mobile spray devices, an automatic nutrient solution circulation control system (liquid pump, liquid pump, liquid level sensor), and LED light source bars with adjustable spectrum and brightness, among other functional components. These components, combined with automatic drive components and sensing systems, can achieve highly automated, precise, and independent control of temperature, humidity, air circulation, water supply, nutrient solution supply, and light conditions in each cultivation unit, ensuring the accuracy and stability of the experimental environment. 3. High adaptability to growth environments and full-cycle coverage: The device, through flexible temperature regulation (heating tubes and cooling fans), uniform humidity control (atomizing nozzles), adjustable spectrum and brightness LED light source bars, and a lifting and adjusting door driven by a rotating motor, can adapt to the specific environmental needs of seeds at different growth stages, from germination to seedling. In particular, the lifting door allows for flexible adjustment of the internal space, and the cooling airflow from the light source bars can also assist in temperature regulation, achieving coordinated control of light and temperature, thus improving the device's adaptability to the entire seed life cycle. 4. High degree of automation, reducing manual intervention and errors: The device achieves automation in multiple aspects. For example, the mobile spray device automatically reciprocates via a drive component, ensuring uniform water supply and reducing errors from manual watering; the nutrient solution carrier tray uses a level sensor to link the addition and extraction pumps, achieving automatic circulation and precise level control of the nutrient solution, eliminating the need for frequent manual operation; the lifting and adjusting door is also automatically raised and lowered by a rotary motor. These automated designs significantly reduce labor costs, minimize errors that may be introduced by human operation, and ensure the accuracy of the experiment. 5. Compact structure, easy observation, and stable and reliable environment: The overall structure is compact, fully functional, and easy to operate and manage. The transparent sealing plate on the outside of the support frame, as well as the heat insulation layer and sealing strip of the heat-insulating bearing device, not only enhance the sealing and heat preservation performance of the cultivation unit, reduce the impact of external environmental fluctuations, and ensure the stability of the internal environment, but also provide an interference-free real-time visualization observation window, allowing researchers to directly monitor the seed growth status without frequently opening the device, further ensuring the constancy of experimental conditions.

Therefore, they should not be construed as limitations on this invention.

[0018] Combination Figures 1-7 As shown, a seed growth characteristic control cultivation device includes a support frame 1, on which at least two independent seed cultivation units are spaced apart to achieve control cultivation of seed growth characteristics. These units are a first seed cultivation device 2, a second seed cultivation device 3, and a third seed cultivation device 4. The first seed cultivation device 2 includes a heat-insulating support device 21, on which several ventilation fans 22 are arranged on both sides. A mobile spray device 23 is installed at the upper end of the heat-insulating support device 21. A seed cultivation tray 24 is disposed inside the heat-insulating support device 21. An atomizing device 25 is installed around the inner side wall of the heat-insulating support device 21. A lifting and adjusting door 26 is installed on one side of the heat-insulating support device 21. By setting at least two independent seed cultivation units on the support frame, a basic structural support is provided for the control experiment of seed growth characteristics, and multiple groups of seed cultivation can be carried out simultaneously. Each cultivation unit integrates functional components such as ventilation fans, mobile spray devices, and atomizing devices, which can provide a basic ventilation, water supply, and humidification environment for seed growth. The overall structure is compact and functional, which facilitates the operation and management of subsequent control experiments.

[0019] The insulation support device 21 includes an insulation box 211, inside which a heating pipe 212 and a cooling fan 213 are installed. A ventilation fan mounting hole 214 is provided on the insulation box 211 corresponding to the installation position of the ventilation fan 22. The insulation box 211 also has a drain outlet 215. The atomizing device 25 includes an atomizing connecting pipe 251 and several atomizing nozzles 252 arranged on the atomizing connecting pipe 251. The atomizing connecting pipe 251 is located inside the insulation box 211. The heating pipe and cooling fan 212 are integrated into the insulation support device. The combination of cooling fans allows for flexible temperature adjustment within the cultivation unit, adapting to the temperature requirements of different seed growth stages. The atomizing connection pipe and nozzle design ensure more even water mist diffusion within the cultivation unit, improving humidity control uniformity. The configuration of ventilation fan mounting holes and drainage outlets ensures airflow within the unit while preventing water accumulation, further enhancing the environmental control capabilities and ease of use of the insulation box. The mobile spray device 23 includes a crossbeam 231, on which a connecting pipe 232 and spray nozzles 233 are mounted. The mobile spray device 23 also includes a drive assembly for its movement. The drive assembly includes a fixed plate 234 connected to the crossbeam 231 and a first rotating motor 235 mounted on the fixed plate 234. The output end of the first rotating motor 235 is connected to a rotating gear 236, which meshes with a rack 237 mounted on the insulation support device 21. The drive assembly controls the forward and reverse rotation of the first rotating motor 235, driving the rotating gear 236 along... The rack 237 reciprocates to drive the mobile spraying device 23 to reciprocate within the heat-insulating bearing device 21 along the extension direction corresponding to the crossbeam 231. The mobile spraying device achieves reciprocating movement through the drive component, which can drive the spray nozzles to evenly cover the seed area within the cultivation unit, avoiding the problem of uneven watering in certain areas. The meshing structure between the rotating gear and the rack is stable and the transmission is reliable, ensuring the smoothness of the spraying device's movement, effectively improving the uniformity of water supply and the degree of automation of the spraying operation, and reducing the error of manual watering.The seed cultivation tray 24 includes a seed germination tray 241 and a nutrient solution carrying tray 242 disposed below the seed germination tray 241. The seed germination tray 241 and the nutrient solution carrying tray 242 are spaced apart by raised blocks 243. The seed germination tray 241 has multiple root growth holes 244 for the seed roots to pass through. The nutrient solution carrying tray 242 is equipped with a nutrient solution adding pump 245, a nutrient solution extracting pump 246, and a nutrient solution level sensor 247 for detecting the nutrient solution level. The nutrient solution level sensor 247 is electrically connected to the nutrient solution adding pump 245 and the nutrient solution extracting pump 246. When the nutrient solution level in the nutrient solution carrying tray 242 is detected by the nutrient solution level sensor 247 as being lower than a preset lower threshold, the nutrient solution adding pump 245 is triggered to start. Nutrient solution is added to the nutrient solution carrier tray 242. When the liquid level sensor 247 detects that the nutrient solution level is higher than the preset upper limit threshold or that the liquid needs to be replaced, the pump 246 is triggered to start and drain excess nutrient solution from the nutrient solution carrier tray 242, thus achieving automatic circulation and regulation of the nutrient solution. The root growth holes of the seed germination tray provide extension space for seed root growth. Combined with the spaced design of the raised blocks, this allows the roots to contact the nutrient solution while preventing the seeds from being soaked in water and rotting. The linkage control of the liquid level sensor with the adding and draining pumps achieves automatic circulation and precise control of the nutrient solution, eliminating the need for frequent manual operation. This reduces labor costs and avoids problems of insufficient or excessive nutrient solution, ensuring the health of the seed root system. Healthy growth; the lifting and adjusting door 26 includes a lifting door 262 and a second rotary motor 261 for driving the lifting door 262 to rise and fall. The second rotary motor 261 is located on the side wall of the heat-insulating support device 21. The second rotary motor 261 is connected to the lifting door 262 through a transmission structure to drive the lifting door 262 to move up and down along the side wall of the heat-insulating support device 21, thereby adjusting the rise and fall of air and temperature inside the heat-insulating support device 21. The lifting door is automatically raised and lowered by the first rotary motor, which is labor-saving and has higher adjustment accuracy; the internal space height of the heat-insulating support device can be flexibly changed, thereby adjusting the air circulation efficiency and temperature distribution within the unit, adapting to the different spatial and environmental needs of seeds from germination to seedling stages. This design improves the adaptability of the device to the entire seed growth cycle. The lighting system 5 includes a lighting cover 51, with a blower 53 on top of the lighting cover 51. At least one light source rod 52 is arranged inside the lighting cover 51. The lighting cover 51 is independently set up for the upper area of ​​each seed cultivation unit. The light source rod 52 is used to provide growth lighting to the seed cultivation units below. Each cultivation unit corresponds to an independent lighting system, which can realize independent control of the light conditions of different units, providing support for the light variable in the control experiment. The combination of the blower and the lighting cover can not only dissipate the working heat of the light source in time and ensure the stability and service life of the light source, but also provide lighting for the cultivation units below, taking into account both light supply and equipment reliability.The light source rod 52 is an LED light source rod with adjustable spectrum and brightness. The fan 53 works in conjunction with the heat dissipation structure inside the lighting cover 51 to dissipate the heat generated by the light source rod 52 during operation, preventing overheating of the light source from affecting the stability of the lighting. At the same time, it delivers warm air downwards. The adjustable spectrum and brightness of the LED light source rod can match the light requirements of different seed growth stages (such as germination and leaf expansion), improving the adaptability of light to seed growth. The fan not only solves the problem of heat dissipation of the light source, but also delivers warm air downwards to help regulate the temperature within the cultivation unit, achieving coordinated control of light and temperature, and further optimizing the seed growth environment. The operating parameters of the lighting system 5, heating tube 212, cooling fan 213, and atomizing device 25 of various seed cultivation units can be set independently to create differentiated temperature, humidity, and light conditions in different seed cultivation units, meeting the needs of control experiments on multiple groups of seed growth characteristics. The temperature, humidity, and light parameters of each cultivation unit can be set independently, enabling the construction of multiple differentiated growth environments within the same device, meeting the needs of multi-variable and multi-group seed growth characteristic control experiments. The device meets the requirements of experimental design. By controlling single or multiple variables, the impact of different environmental factors on seed growth can be analyzed more accurately, improving the comprehensiveness and data reference value of the control experiment. A transparent sealing plate is set around the outer edge of the support frame 1 for heat preservation and observation of seed development. The inner wall of the heat preservation box 211 is fitted with a heat insulation layer, and a sealing strip is provided at the mating edge of the heat preservation box 211 and the lifting door 262 to enhance the sealing and heat preservation performance of the heat preservation support device 21. The transparent sealing plate on the outer side of the support frame ensures the heat preservation effect while allowing direct observation of seed growth status without frequent opening of the device, reducing the interference of the external environment on the cultivation unit. The heat insulation layer and sealing strip of the heat preservation box further enhance the sealing and heat preservation performance of the unit, reducing the impact of external environmental fluctuations on internal cultivation conditions, and improving the stability of the control experiment environment and the accuracy of data. This device can realize automated and precise control of environmental factors such as temperature, humidity, light, and nutrient solution in each cultivation unit to meet the control cultivation needs of multiple groups of seeds' growth characteristics.

[0020] Before the experiment begins, based on the requirements of the control cultivation, different environmental parameters are set for the first seed cultivation device 2, the second seed cultivation device 3, and the third seed cultivation device 4, which are set at intervals on the support frame 1. These parameters include temperature threshold, humidity range, light intensity / spectrum, spraying frequency, and nutrient solution level threshold. This enables the independent initialization of multiple cultivation environments and lays the foundation for subsequent control experiments. Subsequently, the seeds to be cultivated are evenly distributed onto the seed germination trays 241 in each cultivation unit. The seed germination trays 241 are separated from the nutrient solution carrying trays 242 below by the raised blocks 243, ensuring that the seeds do not directly contact the nutrient solution, while reserving space for root and stem growth. Temperature control is achieved through the heating tubes 212 and cooling fans 213 in the heat preservation carrying device 21: when the temperature in the cultivation unit is lower than the preset lower limit, the heating tubes 212 automatically start to heat up; when the temperature is higher than the preset upper limit, the cooling fans 213 start to cool down. Together with the heat insulation layer on the inner wall of the heat preservation box 211 and the sealing strips on the edge that cooperate with the lifting door 262, heat loss is reduced and the temperature in the unit is kept stable. Humidity control is achieved through the combined action of an atomizing device 25 and a ventilation fan 22: the atomizing connecting pipe 251 of the atomizing device 25 sprays water mist evenly into the insulated box 211 through multiple atomizing nozzles 252, increasing the ambient humidity; the ventilation fan 22 achieves air circulation within the unit through the ventilation fan mounting holes 214 on the insulated box 211, preventing excessive humidity from causing mold, and also assisting in regulating temperature distribution; excess water is discharged through the drain outlet 215 of the insulated box 211 to prevent water residue from affecting seed growth. The independently installed lighting system 5 above each cultivation unit is activated synchronously. The adjustable spectrum and brightness LED light source rods 52 inside the lighting lamp cover 51 provide light suitable for the seed's growth stage according to preset parameters. The heat generated by the light source rods 52 during operation is discharged through the blower 53 on the top of the lighting lamp cover 51 in conjunction with the internal heat dissipation structure, preventing the light source from overheating and affecting the stability of the lighting; at the same time, the blower 53 delivers warm air downwards, which can help regulate the temperature inside the cultivation unit, achieving coordinated control of light and temperature.Because each lighting system has 5 independently set parameters, it can create differentiated light environments in different cultivation units, supporting control experiments of light variables. Water supply is achieved through a mobile spray device 23: after the first rotating motor 235 of the drive component starts, the rotating gear 236 at its output end meshes with the rack 237 on the heat preservation support device 21, converting the rotational motion of the motor into linear reciprocating motion (refer to the gear and rack transmission principle), thereby driving the crossbeam 231 and its connecting pipe 232 and spray nozzle 233 to move back and forth along the extension direction of the crossbeam, ensuring that the spray nozzle 233 evenly covers the seed area, achieving precise and uniform water supply. Nutrient solution control adopts an automatic circulation mode. The liquid level sensor 247 on the nutrient solution support chassis 242 detects the liquid level in real time. When the liquid level is lower than the preset lower threshold, the liquid pump 245 is triggered to start replenishing the nutrient solution; when the liquid level is higher than the preset upper threshold or the nutrient solution needs to be replaced, the liquid pump is triggered. Pump 246 is activated to discharge excess or waste nutrient solution; the seed roots extend through the root growth holes 244 on the seed germination tray 241 into the nutrient solution carrying tray 242 to absorb nutrients, achieving synergy between healthy root growth and precise nutrient solution control. Throughout the cultivation process, the lighting system 5, heating tube 212, cooling fan 213, atomizing device 25, and mobile spraying device 23 of various sub-cultivation units operate independently according to preset parameters, forming differentiated growth environments. Each system reduces human intervention through automated linkage (such as the linkage between the liquid level sensor and the liquid pump, and the linkage between temperature and humidity and the heating / cooling / atomizing device), ensuring a stable cultivation environment. At the same time, with the help of a sealed heat preservation structure and a transparent observation design, both environmental stability and experimental observation convenience are taken into account, ultimately realizing the synchronous cultivation of multiple groups of seeds under different environmental factors, providing reliable experimental conditions for the precise analysis of the impact of environmental factors on seed growth characteristics.
