Description

Technical Field

[0001] This invention belongs to the field of plant culture technology, specifically a seedling cultivation device for cotton breeding. Background Technology

[0002] A seedling cultivation device for cotton breeding integrates technologies such as temperature and humidity control, light regulation, automatic irrigation, nutrient supply, and intelligent monitoring to provide an ideal growth environment for cotton seeds, promoting their rapid and healthy growth. Through modern automated equipment and intelligent management, seedling cultivation efficiency and quality can be greatly improved, while reducing labor costs.

[0003] Existing technical document publication number CN217657358U discloses a seedling cultivation box for cotton breeding. Inside the bottom outer shell, there are four lifting rods. Side plates are located between two adjacent lifting rods, sliding within the bottom outer shell. One side plate houses a fan, and the other a temperature sensor. A drawer is located inside the bottom outer shell, with a top shell on each of the four lifting rods. The drawer has two rows of seedling positions, each with a misting nozzle above it. A water distribution pipe is located below the top shell, and a water storage tank is located on one side of the bottom outer shell. A water delivery hose is connected to the outlet of the water storage tank, passing through the top shell and connecting to the water distribution pipe. In this invention, the seedling positions are located on the drawer. When seedlings grow to a certain height in their positions and need transplanting, the drawer can be removed from the device, allowing for external transplantation. This external transplantation is less difficult due to the absence of an external obstruction.

[0004] While the aforementioned application can reduce the difficulty of seedling transplanting, the watering process during seedling planting involves indiscriminate application of water through misting nozzles. The amount of water used is entirely dependent on the workers' habits and experience, which may result in either too much or too little water. Sometimes, excessive watering prevents timely drainage, leading to overly moist soil or even waterlogging, which in turn causes root hypoxia, root rot, and ultimately, seedling death. Conversely, insufficient watering deprives the seedling roots of enough moisture, leading to drought and water shortage, which hinders the normal growth and development of the seedlings. Summary of the Invention

[0005] To address the problems of excessive or insufficient irrigation water mentioned in the background art, the present invention provides a seedling cultivation device for cotton breeding.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seedling cultivation device for cotton breeding, comprising a breeding box, a cabinet door hinged to one side of the outer wall of the breeding box, a collection shell fixedly connected to the bottom of the inner wall of the breeding box, and a water storage tank fixedly connected to the top of the inner wall of the breeding box; further comprising a seedling cultivation mechanism, the seedling cultivation mechanism comprising a support frame fixedly connected to the bottom of the inner wall of the collection shell, a fixed rod fixedly connected to the center of the bottom of the inner wall of the collection shell, a rotating sleeve rotatably connected to the outer wall of the fixed rod, and bearing plates fixedly connected to the outer walls of both ends of the rotating sleeve; a water spraying assembly is provided on the top of the bearing plate for precise watering of cotton seedlings; an electric telescopic rod is driven, which drives the connecting frame rod and the irregular frame to descend vertically; the irregular frame drives the fixed plate and the soil detector to descend; the probe of the soil detector enters the soil inside the round basin during the descent to detect the soil moisture content; the acquisition of soil moisture data helps to accurately understand the soil moisture content and avoid over-irrigation or under-irrigation.

[0007] Preferably, the water spray assembly includes a circular basin that is disposed in contact with the top of the support plate. The bottom of the inner wall of the circular basin has multiple drain outlets, one end of which penetrates the support plate and extends to the outside of the support plate.

[0008] Preferably, the bottom of the water storage tank is connected to four vertical cylinders, and each of the two ends of one side of the vertical cylinders is connected to a square tube. A water sprayer is fixedly connected to the bottom of the square tube, and four arc-shaped grooves are opened on the top of the support plate.

[0009] Preferably, one end of the vertical cylinder is slidably connected to the inner wall of the arc-shaped groove, and four electric telescopic rods are fixedly connected to the top of the support frame, with a connecting frame rod fixedly connected to the bottom of each electric telescopic rod.

[0010] Preferably, both ends of the connecting frame rod are fixedly connected to irregularly shaped frames, one side of the irregularly shaped frame is fixedly connected to a fixing plate, and the bottom of the fixing plate is fixedly connected to a soil detector.

[0011] Preferably, the ends of the irregularly shaped frame are provided with stabilizing components, the stabilizing components including rotating telescopic frame rods hinged to both ends of the irregularly shaped frame, and the bottom ends of the rotating telescopic frame rods are hinged with sliders.

[0012] Preferably, a round rod is slidably connected to the inner wall of the slider, one end of the round rod is fixedly connected to the side wall of the support frame, and a clamping plate is fixedly connected to one end of the slider.

[0013] Preferably, one end of the clamping plate is provided with an auxiliary component, the auxiliary component including a slanted rod fixedly connected to the end of the clamping plate away from the slider, a rotating frame hinged to the top of one end of the slanted rod, and a horizontal block hinged to the top end of the rotating frame.

[0014] Preferably, a rubber block is fixedly connected to the bottom of the horizontal block, the bottom of the rubber block contacts the top side of the round basin, and strip plates are fixedly connected to both ends of one side of the horizontal block, with an elastic support rod slidably connected to one end of the side wall of the strip plate.

[0015] Preferably, a strip-shaped shell is fixedly connected to one end of the elastic frame rod. A heating tube is fixedly connected to both ends of the inner wall of the strip-shaped shell. A cleaning strip is fixedly connected to the side of the strip-shaped shell away from the elastic frame rod. When the soil detector rises, the horizontal block drives the strip plate to descend, which in turn pushes the elastic frame rod, the strip-shaped shell, and the cleaning strip downwards together. During this process, the outer wall of the rising soil detector probe contacts the side wall of the descending cleaning strip, thereby scraping and cleaning the outer wall of the probe and removing soil residue adhering to its surface. Furthermore, a heating tube is installed inside the strip-shaped shell. This heating tube heats the probe, transferring heat to the strip-shaped shell and further to the cleaning strip. This heat conduction allows the cleaning strip to effectively heat and dry the outer wall of the probe. Through this combination of heating and drying, the cleaning strip not only scrapes away moist soil from the probe but also helps remove residual moisture, preventing excessive adhesion of moist soil on the probe surface. This ensures that the soil detector can work more cleanly and effectively the next time it is used, improving the accuracy and stability of soil testing. This design also reduces the hardening that may occur on the surface of the soil detector after the soil dries, preventing soil residue from damaging the equipment, ensuring long-term stable operation, thereby extending the service life of the soil detector and improving the equipment's working efficiency.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention utilizes a seedling raising mechanism to plant cotton seedlings in the soil of round pots. Multiple planted pots are then placed on top of a support plate, aligning the drainage outlets of the pots with those of the support plate. The cabinet door is closed, and simultaneously, an electric telescopic rod is activated. This rod lowers a connecting frame and a shaped frame vertically. The shaped frame then lowers a fixed plate and a soil detector. During descent, the soil detector's probe enters the soil within the pot to measure its moisture content. This soil moisture data helps accurately assess soil moisture levels, preventing over- or under-irrigation and providing the optimal water environment for cotton growth. The precise values ​​from the soil detector control the water pump's power. The pump controls the water flow from the storage tank through a vertical cylinder into a square tube, which then flows into a sprinkler system. The sprinkler system irrigates the cotton seedlings in the round pots. The irrigation volume is adjusted based on real-time soil moisture data, ensuring precise water supply to the cotton and improving crop growth stability and health.

[0018] This invention employs a seedling raising mechanism. During the descent of the irregularly shaped frame, the frame drives a rotating telescopic rod, which in turn lowers the frame. This telescopic rod causes a slider to slide laterally along the outer wall of the circular rod. As the two sliders approach each other, they move the clamping plates, which clamp and position the bottom of the circular pot, preventing the pot from wobbling or shifting when the soil detector is inserted. This ensures the soil detector can stably enter the soil and effectively measure moisture or other soil properties. After testing, the electric telescopic rod drives the connecting rod upwards. This upward movement indirectly removes the soil detector from the soil, preventing the probe from remaining inside the soil for extended periods and avoiding potential corrosion or damage from prolonged exposure to moist soil. Intermittent control of the electric telescopic rod allows for intermittent testing by the soil detector.

[0019] This invention, through the setting of a seedling raising mechanism, allows two clamping plates to move away from each other when the soil detector is pulled out. These clamping plates, in turn, cause two inclined rods to move away from each other, which in turn cause two rotating frames to move away from each other. During this movement, the rotating frames cause a horizontal block to descend, which in turn causes a rubber block to descend. As the rubber block descends, it contacts the top side wall of the round pot, pressing down on the pot and preventing it from tilting when the soil detector is pulled out. This ensures the round pot remains stable throughout the entire operation. As the soil detector rises, the crossbar drives the strip plate downwards. The strip plate, in turn, drives the elastic support rod, strip shell, and cleaning strip downwards. During this movement, the outer wall of the rising soil detector probe contacts the side wall of the descending cleaning strip, scraping and cleaning the probe's outer wall. Furthermore, because the inner wall of the strip shell is equipped with heating elements, the heating elements raise the temperature, and heat is transferred through the strip shell to heat the cleaning strip, allowing it to dry the outer wall of the soil detector probe. This effectively prevents excessive wet soil from adhering to the probe, helping to maintain the cleanliness and accuracy of the equipment. In this way, soil residue will not interfere with subsequent detection or cause equipment damage. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, the present invention provides a seedling cultivation device for cotton breeding, including a breeding box 1, a cabinet door 2 hinged to one side of the outer wall of the breeding box 1, a collection shell 3 fixedly connected to the bottom of the inner wall of the breeding box 1, and a water storage tank 4 fixedly connected to the top of the inner wall of the breeding box 1, and also includes;

[0032] The seedling raising mechanism 5 includes a support frame 51 fixedly connected to the bottom of the inner wall of the collecting shell 3. A fixed rod 52 is fixedly connected to the center of the bottom of the inner wall of the collecting shell 3. A rotating sleeve 53 is rotatably connected to the outer wall of the fixed rod 52. A bearing plate 54 is fixedly connected to the outer walls of both ends of the rotating sleeve 53. A water spraying component 55 is provided on the top of the bearing plate 54 for precise watering of cotton seedlings.

[0033] The cotton seedlings are planted in the soil inside the round pot 551. Then, multiple planted round pots 551 are placed on top of the support plate 54, so that the drainage outlet of the round pot 551 is connected to the drainage outlet of the support plate 54, and the cabinet door 2 is closed.

[0034] The water spray assembly 55 includes a circular basin 551 that is positioned on the top of the support plate 54. The bottom of the inner wall of the circular basin 551 has multiple drain outlets, one end of which passes through the support plate 54 and extends to the outside of the support plate 54.

[0035] The bottom of the water storage tank 4 is connected to four vertical cylinders 552. Both ends of one side of the vertical cylinders 552 are connected to square tubes 553. The bottom of the square tubes 553 is fixedly connected to a water sprayer 554. The top of the support plate 54 is provided with four arc-shaped grooves 555.

[0036] The water pump controls the water flow inside the water storage tank 4 to enter the inside of the square tube 553 through the vertical cylinder 552. The water flow then enters the inside of the water sprayer 554 through the square tube 553, and the water flows through the water sprayer 554 to irrigate the cotton seedlings inside the round basin 551.

[0037] One end of the vertical cylinder 552 is slidably connected to the inner wall of the arc groove 555. Four electric telescopic rods 556 are fixedly connected to the top of the support frame 51. A connecting frame rod 557 is fixedly connected to the bottom of the electric telescopic rods 556.

[0038] Both ends of the connecting rod 557 are fixedly connected to the outer walls of the irregular frame 558, and a fixing plate 559 is fixedly connected to one side of the irregular frame 558. A soil detector 5510 is fixedly connected to the bottom of the fixing plate 559.

[0039] The electric telescopic pole 556 is driven, which in turn drives the connecting frame pole 557 and the irregular frame 558 to descend vertically. The irregular frame 558 drives the fixing plate 559 and the soil detector 5510 to descend. During the descent, the probe of the soil detector 5510 will enter the soil inside the round basin 551 to detect the moisture content inside the soil.

[0040] The end of the irregular frame 558 is provided with a stabilizing component 56. The stabilizing component 56 includes a rotating telescopic frame rod 561 hinged to both ends of the irregular frame 558. A slider 562 is hinged to the bottom end of the rotating telescopic frame rod 561.

[0041] A round rod 563 is slidably connected to the inner wall of the slider 562. One end of the round rod 563 is fixedly connected to the side wall of the support frame 51, and a clamping plate 564 is fixedly connected to one end of the slider 562.

[0042] Using the above scheme: When the irregular frame 558 is descending, the irregular frame 558 drives the rotating telescopic frame rod 561 to descend. The rotating telescopic frame rod 561 drives the slider 562 to slide laterally along the outer wall of the round rod 563. The two sliders 562 move closer to each other, and the sliders 562 drive the clamping plate 564 to move. During the process of the two clamping plates 564 moving closer to each other, the bottom two sides of the round basin 551 can be clamped and positioned.

[0043] like Figures 1 to 9 As shown, an auxiliary component 57 is provided at one end of the clamping plate 564. The auxiliary component 57 includes a diagonal bar 571 fixedly connected to the end of the clamping plate 564 away from the slider 562. A rotating frame 572 is hinged to the top of one end of the diagonal bar 571, and a horizontal block 573 is hinged to the top end of the rotating frame 572.

[0044] A rubber block 574 is fixedly connected to the bottom of the horizontal block 573. The bottom of the rubber block 574 contacts the top side of the round basin 551. A strip plate 575 is fixedly connected to both ends of one side of the horizontal block 573. An elastic support rod 576 is slidably connected to one side wall of the strip plate 575.

[0045] When the soil detector 5510 is pulled out, the two clamping plates 564 move away from each other. The two clamping plates 564 drive the two inclined rods 571 to move away from each other. The two inclined rods 571 drive the two rotating frames 572 to move away from each other. During the process of the two rotating frames 572 moving away from each other, the horizontal block 573 will move downward. The horizontal block 573 will drive the rubber block 574 to move downward. When the rubber block 574 moves downward, it will contact the top side wall of the round basin 551 and press down on the round basin 551.

[0046] One end of the elastic support rod 576 is fixedly connected to a strip shell 577. A heating tube 578 is fixedly connected to both ends of the inner wall of the strip shell 577. A cleaning strip 579 is fixedly connected to the side of the strip shell 577 away from the elastic support rod 576.

[0047] The above scheme is adopted as follows: When the soil detector 5510 rises, the horizontal block 573 drives the strip plate 575 to descend, which in turn causes the strip plate 575 to push the elastic frame rod 576, the strip shell 577, and the cleaning strip 579 downward together. During this process, the outer wall of the rising soil detector 5510 probe comes into contact with the side wall of the descending cleaning strip 579, thereby scraping and cleaning the outer wall of the probe, removing soil residues attached to its surface. A heating tube 578 is installed inside the strip shell 577. The heating tube heats up, and the heat is transferred to the strip shell 577 and further conducted to the cleaning strip 579. This heat conduction allows the cleaning strip 579 to effectively heat and dry the outer wall of the probe. Through this combination of heating and drying, the cleaning strip 579 can not only scrape off the moist soil on the probe but also help remove residual moisture.

[0048] Working principle and usage process of this invention:

[0049] Cotton seedlings are planted in the soil inside round pots 551. Multiple planted round pots 551 are then placed on top of a support plate 54, aligning the drainage outlets of the round pots 551 with those of the support plate 54. The cabinet door 2 is closed, and simultaneously, the electric telescopic rod 556 is activated. The electric telescopic rod 556 drives the connecting frame rod 557 and the irregularly shaped frame 558 to descend vertically. The irregularly shaped frame 558 then drives the fixing plate 559 and the soil detector 5510 to descend. During the descent, the probe of the soil detector 5510 enters the soil inside the round pots 551 to detect the soil moisture content. Obtaining soil moisture data helps to accurately understand the soil moisture content, avoiding over-irrigation or under-irrigation, thus providing the most suitable water environment for cotton growth. The water pump power is controlled by the precise value detected by the soil detector 5510. The water pump controls the water flow inside the water storage tank 4 to enter the inside of the square tube 553 through the vertical tube 552. The water flow enters the inside of the sprinkler 554 through the square tube 553. The water flow irrigates the cotton seedlings inside the round pot 551 through the sprinkler 554. The irrigation amount is adjusted according to the real-time data of soil moisture, ensuring that the cotton in the round pot can receive precise water supply, improving the stability and health of crop growth.

[0050] As the irregular frame 558 descends, it drives the rotating telescopic frame rod 561 to descend as well. The rotating telescopic frame rod 561 drives the slider 562 to slide laterally along the outer wall of the round rod 563. The two sliders 562 move closer to each other, and the sliders 562 drive the clamping plate 564 to move. As the two clamping plates 564 move closer to each other, they can clamp and position the bottom sides of the round basin 551, preventing the round basin 551 from shaking or shifting when the soil detector 5510 is inserted into the round basin 551. This ensures that the soil detector 5510 can stably enter the soil and perform effective measurements of moisture or other soil properties. After the test is completed, the electric telescopic rod 556 drives the connecting rod 557 to rise. When the connecting rod 557 rises, it can indirectly drive the soil detector 5510 to detach from the soil, preventing the probe of the soil detector 5510 from remaining in the soil for a long time. This avoids corrosion or damage that may be caused by long-term exposure to moist soil. By intermittently controlling the operation of the electric telescopic rod 556, the soil detector 5510 can perform intermittent testing.

[0051] When the soil detector 5510 is pulled out, the two clamping plates 564 move away from each other. The two clamping plates 564 drive the two inclined rods 571 to move away from each other. The two inclined rods 571 drive the two rotating frames 572 to move away from each other. During the process of the two rotating frames 572 moving away from each other, the horizontal block 573 will move downward. The horizontal block 573 will drive the rubber block 574 to move downward. When the rubber block 574 moves downward, it will contact the top side wall of the round basin 551 and press down on the round basin 551 to prevent the round basin 551 from tilting when the soil detector 5510 is pulled out, thus ensuring that the round basin remains stable throughout the entire operation. When the soil detector 5510 rises, the cross block 573 drives the strip plate 575 to descend. The strip plate 575 then drives the elastic support rod 576, the strip shell 577, and the cleaning strip 579 to descend. At this time, the outer wall of the probe of the rising soil detector 5510 comes into contact with the side wall of the descending cleaning strip 579, thus scraping and cleaning the outer wall of the probe. Furthermore, because the inner wall of the strip shell 577 is equipped with a heating tube 578, the heating tube 578 heats the probe, and the heat is transferred through the strip shell 577 to heat the cleaning strip 579, allowing the cleaning strip 579 to dry the outer wall of the probe of the soil detector 5510. This effectively prevents excessive wet soil from adhering to the probe, helping to maintain the cleanliness and accuracy of the equipment. In this way, soil residue will not interfere with subsequent detection or cause equipment damage.
