Description

Technical Field

[0001] This application relates to the technical field of vegetable breeding, and in particular to an automatic grading sprinkler irrigation system and method for vegetable seedlings. Background Technology

[0002] Currently, with the development of greening cultivation technology, indoor seedling cultivation has become an inevitable trend. Indoor seedling cultivation saves both costs and space, offering significant advantages over traditional methods. As garden seedling cultivation gradually moves towards intensification and large-scale operations, seedbed equipment is increasingly being used in seedling cultivation. By planting seedlings on seedbeds and then placing them in greenhouses for further cultivation, the survival rate of seedlings can be greatly improved.

[0003] The new sprinkler irrigation method now uses mobile seedbeds and a pass-through sprinkler system. The specific operation is as follows: 72 vegetable seeds are sown in a seedling tray filled with culture medium, and 48 trays are placed together on a mobile seedbed. Guide rails are laid under the mobile seedbeds, and 24 seedbeds form a group that can move in an orderly manner under the control of an automated system. A pass-through sprinkler system is installed above the seedbeds, containing sprinkler devices. When the mobile seedbeds pass underneath, the sprinkler system activates, irrigating the vegetable seedlings in the seedbeds. The mobile seedbeds and the pass-through sprinkler system work together to complete the irrigation of the vegetable seedlings.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: when seedlings in multiple seedbeds are at different growth stages, the amount of water required is different. The above watering method cannot meet the requirement of watering appropriately according to the growth of the seedlings, resulting in poor seedling growth or drowning of the seedlings, which affects the product quality of the seedlings. Summary of the Invention

[0005] In order to reduce the impact on the quality of seedling products, this application provides an automatic grading sprinkler irrigation system and method for vegetable seedlings.

[0006] Firstly, this application provides an automatic grading and sprinkler irrigation system for vegetable seedlings, which adopts the following technical solution:

[0007] An automatic grading sprinkler irrigation system for vegetable seedlings includes a frame, a planting mechanism, and a sprinkler irrigation mechanism. The planting mechanism includes a moving component, seedling trays, and seedbeds. The seedbeds are slidably mounted on the frame via the moving component. Multiple seedling trays for cultivating seedlings are provided on the seedbeds. The sprinkler irrigation mechanism is mounted on the frame and sprays water onto the seedbeds it passes through. A grading control mechanism is mounted on the frame. The grading control mechanism includes an identifier, an identification component, and a control component. The identifier is located on the seedbed, and the identification component is located on the frame. The identification component identifies the recorded signal of the identifier and transmits it to the control component. The control component is located on the frame and controls the water output of the sprinkler irrigation mechanism.

[0008] By adopting the above technical solution, during seedling sprinkler irrigation, the moving component drives the seedbed to slide along a predetermined path. The seedbed moves the seedlings on the seedling trays to below the sprinkler mechanism. The identification component recognizes the information of the identification piece on the seedbed, determines the current growth status of the seedlings, and transmits the signal to the control component. The control component controls the water output of the sprinkler mechanism, which then irrigates the seedlings on the seedbed. The automatic graded sprinkler system can provide appropriate water volume according to the growth status of the seedlings, providing a suitable water environment for the seedlings and reducing the occurrence of root rot due to excessive water and growth restriction due to insufficient water, thereby improving the quality of the seedlings.

[0009] Optionally, the identification element is a magnetic identification plate, which is set on the seedbed, and the identification element is a Hall sensor, which is set on the frame and located on one side of the sprinkler mechanism.

[0010] By adopting the above technical solution, during seedling sprinkler irrigation, the moving component drives the seedbed to slide along a predetermined path. The seedbed moves the seedlings on the trays to below the sprinkler mechanism. The Hall sensor detects the magnetic markings on the magnetic tags and transmits the signal to the control component. The control component controls the sprinkler mechanism to perform fixed-volume irrigation. When the next set of magnetic tags on the seedbed is transported to the Hall sensor, the Hall sensor recognizes the magnetic markings and transmits the signal to the control component. The control component then controls the sprinkler mechanism to adjust the water volume and irrigate the trays. The identification and tagging components have a simple structure, fast response, and easy identification, thus simplifying the control of water output and indirectly helping to improve the quality of seedling products.

[0011] Optionally, the magnetic identification tags are provided in multiple sets, with different magnetic forces and each set representing a different growth stage of the seedling.

[0012] By adopting the above technical solution and setting up multiple sets of signs, the various growth stages of seedlings are defined. Generally, seedlings grow in four stages, corresponding to no watering, low watering, medium watering, and high watering, respectively. This allows for precise control of water volume, reducing the occurrence of drought and waterlogging, and further improving seedling quality. Furthermore, the seedling growth cycle is approximately one month, during which only three manual adjustments to the magnetic signs are needed, each taking only three seconds. Compared to the previous method where operators stood beside the sprinkler system to control water flow, this significantly reduces labor costs.

[0013] Optionally, the magnetic sign is an electromagnet, and the magnetic sign is provided with an adjustment mechanism, which adjusts the magnetic force by adjusting the current flowing into the electromagnet.

[0014] By adopting the above technical solution, the water volume for each stage of seedling growth is adjusted accordingly. The current flowing through the electromagnet can be adjusted over time using a regulating mechanism to control the magnitude of the electromagnet's magnetic force. This allows the magnetic force of the electromagnet to vary within a certain range, thereby altering the signal received by the identification component. This enables the control component to adjust the water output of the irrigation mechanism, achieving more precise control and making the water volume more suitable for seedling growth. This reduces water waste while improving seedling quality. Furthermore, compared to permanent magnets, the electromagnet's magnetic force is relatively stable, preventing the magnetic force from gradually weakening and causing the identification component to fail to recognize the seedlings, thus maintaining the quality of the seedlings.

[0015] Optionally, the adjustment mechanism includes an adjustable resistor, a threaded tube, a toggle block, and a drive assembly. The electromagnet, the adjustable resistor, and the power supply form a closed loop. The threaded tube is sleeved on the adjustable resistor and has a groove for the sliding lead of the adjustable resistor to slide. The toggle block is threadedly connected to the threaded tube and pushes the sliding lead of the adjustable resistor to slide. The drive assembly is disposed on the seedbed and is connected to the toggle block, driving the toggle block to rotate.

[0016] By adopting the above technical solution, after the magnetic identification sign is installed on the seedbed, the driving component drives the actuating block to rotate. The rotation of the actuating block causes the sliding lead of the adjustable resistor to slide along the adjustable resistor, making the resistance value in the circuit smaller, thereby increasing the current and the magnetic force of the magnetic identification sign stronger. The magnetic force signal detected by the identification component changes, and the signal is transmitted to the control component. The control component controls the water output of the sprinkler mechanism to spray the seedlings. The set adjustment mechanism allows the magnetic force of the electromagnet to change. The identification component can control the sprinkler mechanism to adjust the water output according to the change of magnetic force, so that the irrigation water volume is consistent with the growth rate of the seedlings at each stage, thereby facilitating the growth of the seedlings and improving the product quality of the seedlings.

[0017] Optionally, the driving assembly includes a driving disk, a driving motor, and a toggle ring. The driving motor is mounted on the seedbed, the driving disk is eccentrically mounted on the output shaft of the driving motor, the toggle ring is mounted on the toggle block, and the toggle ring is provided with a plurality of toggle teeth. One end of the driving disk abuts against the toggle teeth and drives the toggle teeth to rotate.

[0018] By adopting the above technical solution, after installing multiple sets of magnetic identification tags on the seedbed, the drive motor is started. The drive motor drives the drive disc to rotate, which in turn drives the actuating teeth to rotate. The actuating teeth drive the actuating ring to rotate, which in turn drives the actuating block to rotate. The rotating block drives the sliding lead of the adjustable resistor to slide along the adjustable resistor. As time increases, the resistance value in the circuit gradually decreases, thereby increasing the current and the magnetic force of the magnetic identification tag increases. The magnetic force signal detected by the identification component changes and is transmitted to the control component. The control component controls the water output of the sprinkler mechanism and sprays the seedlings. The drive component has a simple structure and can set the rotation speed of the drive motor according to the growth rate of the seedlings, so that the magnetic force of the magnetic identification tag increases with the growth of the seedlings. The water volume is adjusted according to the growth status of the seedlings, which reduces water waste and creates the most suitable growth environment for the seedlings, thereby improving the quality of the seedlings.

[0019] Optionally, a tangential assembly is provided on the seedbed. The tangential assembly includes a tangential switch and a tangential wire. The tangential switch is located at one end of the adjustable resistor and forms a closed loop with the power supply. The other end of the adjustable resistor is provided with the tangential wire and connected to the tangential switch. When the tangential switch is activated, the power supply forms a closed loop through the tangential switch, the tangential wire, and the other end of the adjustable resistor.

[0020] By adopting the above technical solution, when the magnetic force of the magnetic sign reaches the maximum value of the seedling at this stage, the directional switch is activated, so that the other end of the adjustable resistor forms a closed circuit with the power supply and the electromagnet, thereby restoring the resistance value and the magnetic force of the electromagnet to the initial value, which facilitates the monitoring and watering of the same type of seedlings at this growth stage; there is no need to adjust the magnetic force of the magnetic sign, only to switch the connection of the directional switch, which improves work efficiency.

[0021] Optionally, the sprinkler irrigation mechanism includes a sprinkler pipe, a water pump, and a septic tank. The water pump is mounted on the septic tank and connected to the sprinkler pipe. The sprinkler pipe is mounted on the frame and has multiple spray holes. The control assembly includes a control pipe, atomizing nozzles, and a control component. The control pipe is rotatably mounted on the sprinkler pipe and has multiple atomizing holes. The atomizing holes correspond to the spray holes, and water volume is adjusted by rotational misalignment. Each atomizing hole is equipped with an atomizing nozzle. The control component is mounted on the frame and connected to the control pipe, driving the control pipe to rotate.

[0022] By adopting the above technical solution, when the seedlings are sprinkled, the water pump is started, and the water pump delivers the water in the water and fertilizer tank to the sprinkler pipe. According to the magnetic signal identified by the identification device, the control device drives the control pipe to rotate. The atomizing hole of the control pipe is connected to the spray hole, and the water is sprayed onto the seedlings through the atomizing nozzle. The control component has a simple structure and adjusts the water output by misaligning the holes to achieve different water volumes for seedlings in different growth stages.

[0023] Optionally, the control component includes a control motor, a drive gear, and a driven gear. The control motor is mounted on the frame, the drive gear is mounted on the output shaft of the control motor, and the driven gear is mounted on the control tube. The drive gear meshes with the driven gear.

[0024] By adopting the above technical solution, when the seedlings are sprinkled, the water pump is started, and the water pump delivers water from the water-fertilizer tank to the sprinkler pipe. According to the magnetic signal identified by the identification device, the control motor is started, which drives the drive gear to rotate. The drive gear drives the driven gear to rotate, and the driven gear drives the control pipe to rotate. The atomizing hole of the control pipe is connected to the spray hole, and water is sprayed onto the seedlings through the atomizing nozzle. The control device has a simple structure and is easy to operate, making water volume adjustment convenient and improving work efficiency.

[0025] Secondly, the automatic grading and sprinkler irrigation method for vegetable seedlings provided in this application adopts the following technical solution:

[0026] An automatic graded sprinkler irrigation method for vegetable seedlings includes:

[0027] Receive irrigation instructions;

[0028] Based on the irrigation command, the irrigation water reservoir is retrieved;

[0029] Obtain the current growth status of the seedlings, and retrieve the corresponding amount of irrigation water from the irrigation water reservoir based on the growth status of the seedlings;

[0030] Adjust the amount of water sprayed according to the irrigation water volume, and irrigate the seedlings.

[0031] By adopting the above technical solution, when cultivating vegetable seedlings, some seedlings have different growth cycles and planting times, and seedlings at different growth stages have different water requirements. When an irrigation instruction is received, the control equipment starts, retrieves the irrigation water reservoir according to the current irrigation instruction, and obtains the current growth status of the seedlings. Based on the growth status of the seedlings, the corresponding irrigation water volume is matched from the irrigation water reservoir, and then the water volume of the sprinkler is controlled according to the irrigation water volume to irrigate the seedlings. Through the above method, the irrigation water volume can be controlled according to the seedling status, adapting the irrigation to seedlings at different growth stages, creating a relatively better growth environment for the seedlings, reducing the occurrence of overwatering or drought, and improving the product quality of the seedlings.

[0032] In summary, this application includes the following beneficial technical effects:

[0033] 1. During seedling irrigation, the moving component drives the seedbed to slide along a predetermined path. The seedbed moves the seedlings on the trays to below the irrigation mechanism. The identification component recognizes the information on the identification piece on the seedbed, determines the current growth status of the seedlings, and transmits the signal to the control component. The control component controls the water output of the irrigation mechanism, which then irrigates the seedlings on the seedbed. The automatic graded irrigation system can provide appropriate water volume according to the growth status of the seedlings, providing a suitable water environment and reducing the occurrence of root rot from excessive watering and growth restriction from insufficient watering, thereby improving the quality of the seedlings.

[0034] 2. During seedling sprinkler irrigation, the moving component drives the seedbed to slide along a predetermined path. The seedbed moves the seedlings on the trays to below the sprinkler mechanism. The Hall sensor detects the magnetic markings on the magnetic tags and transmits the signal to the control component. The control component controls the sprinkler mechanism to perform fixed-volume irrigation. When the next set of magnetic tags on the seedbed is transported to the Hall sensor, the Hall sensor recognizes the magnetic markings and transmits the signal to the control component. The control component then controls the sprinkler mechanism to adjust the water volume and irrigate the trays. The identification and tagging components are simple in structure, react quickly, and are easy to identify, thus simplifying the control of water output and indirectly helping to improve the quality of seedling products.

[0035] 3. When irrigating seedlings, the water pump is started, which delivers water from the water-fertilizer tank to the irrigation pipe. Based on the magnetic signal detected by the identification device, the control motor is started, which drives the drive gear to rotate. The drive gear drives the driven gear to rotate, which in turn drives the control pipe to rotate. The atomizing holes of the control pipe are connected to the spray holes, and water is sprayed onto the seedlings through the atomizing nozzles. The control device has a simple structure and is easy to operate, making water volume adjustment convenient and improving work efficiency.

[0036] 4. To enable water volume control based on seedling status, adapting irrigation to seedlings at different growth stages, creating a relatively better growth environment for seedlings, reducing the occurrence of overwatering or drought, and improving the quality of seedlings.

[0053] refer to Figure 2 and Figure 5 The movable frame 214 is provided with an identification element 410, which is a magnetic identification plate 411 and there are multiple sets of them. In this embodiment, four sets are preferred. The magnetic force of each set of magnetic identification plates 411 is different. In this embodiment, the magnetic identification plate 411 can be an electromagnet. One set of magnetic identification plates 411 is provided with two magnetic identification plates 411 and is located at both ends of the movable frame 214 respectively. The other three sets of magnetic identification plates 411 are located between the two magnetic identification plates 411 at the above-mentioned ends and are equally spaced. The frame 100 is provided with an identification element 420, which is a Hall sensor. The Hall sensor is fixedly connected to the frame 100 and is located on one side of the irrigation pipe 310. The position of the Hall sensor corresponds to the position of the magnetic identification plate 411.

[0054] refer to Figure 5 , Figure 6 and Figure 7 The movable frame 214 is equipped with an adjustment mechanism 500, which includes a mounting block detachably connected to the movable frame 214. The mounting block has a placement cavity, and a magnetic identification plate 411 is fixedly connected within the placement cavity and located on the side wall of the placement cavity away from the movable frame 214. An adjustable resistor 510 is fixedly connected within the placement cavity, and a tangential component 540 is provided on the adjustable resistor 510. The tangential component 540 includes a tangential wire 542 fixedly connected to one end of the adjustable resistor 510.

The threaded tube 520 is fixedly connected to the adjustable resistor 510. A groove 521 is formed on the threaded tube 520 along its length, allowing the sliding lead of the adjustable resistor 510 to slide. A toggle block is threaded onto the threaded tube 520, and the sliding lead of the adjustable resistor 510 is rotatably connected to the toggle block, with an insulating coating between them. A drive assembly 530 is installed inside the cavity. The moving assembly 530 includes a drive motor 532 fixedly connected to the bottom wall of the mounting cavity. A drive disk 531 is eccentrically connected to the output shaft of the drive motor 532. The drive disk 531 is elongated, with one end away from the drive motor 532 close to the actuating block. An actuating ring 533 is sleeved on a threaded tube 520. The actuating ring 533 is coaxially connected to the actuating block, and multiple actuating teeth 534 are fixedly connected to the actuating ring 533. Any one of the actuating teeth 534 can abut against the drive disk 531 and rotate with the rotation of the drive disk 531. When the drive motor 532 starts, the drive motor 532 drives the drive disk 531 to rotate, and the drive disk 531 drives one of the actuating teeth 534 to rotate until it separates from the actuating tooth 534. After the drive disk 531 rotates one revolution, it abuts against the next actuating tooth 534 and drives it to rotate, thereby realizing the rotation of the actuating ring 533.

[0056] A controller is installed on the frame 100. The controller contains a computer control program, which encodes the corresponding water output for different growth stages of different types of seedlings. The controller is electrically connected to a Hall sensor, a drive motor 532, a sliding motor 211, a control motor 434, and a water pump 320. It controls the start and stop of the drive motor 532, the sliding motor 211, and the water pump 320 through the signal from the Hall sensor.

[0057] The implementation principle of the automatic grading sprinkler irrigation system for vegetable seedlings in this application embodiment is as follows: When watering seedlings, different magnetic identification tags 411 can be installed on the movable frame 214 according to the current growth status of the seedlings; firstly, the sliding motor 211 is started, which drives the roller 213 to rotate, and the roller 213 drives the seedbed 220 on the movable frame 214 to move. The Hall sensor detects the magnetic signal of the magnetic identification tag 411 and transmits it to the controller. After receiving the signal, the controller controls the motor 434 to start. The operating time of the control motor 434 is adjusted and controlled. The control motor 434 drives the drive gear 435 to rotate, the drive gear drives the driven gear 436 to rotate, and the driven gear 436 drives the control tube 431 to rotate. The atomizing hole 433 on the control tube 431 is connected to the spray hole 311 until the degree of connection between the atomizing hole 433 and the spray hole 311 reaches a degree that meets the requirements of the seedling growth stage. Then the water pump 320 is started, and the water pump 320 drives water to spray onto the seedling through the irrigation pipe 310 and the atomizing nozzle 432.

[0058] The drive motor 532 is in a normally open state. The rotation speed of the drive motor 532 can be determined according to the growth cycle of the seedlings and the information is input into the controller. The drive motor 532 drives the drive disk 531 to rotate. The rotation of the drive disk 531 drives the actuating teeth 534 and the actuating ring 533 to rotate. The actuating ring 533 drives the actuating block to rotate along the threaded tube 520 and slide along the length of the threaded tube 520. This causes the sliding lead of the adjustable resistor 510 to slide with the actuating block, causing the resistance value to change. This changes the current entering the electromagnet, causing the magnetic force of the electromagnet to change and be limited to a certain value. After receiving the magnetic force signal, the Hall sensor transmits it to the controller. The controller controls the control motor 434 to adjust the connectivity between the atomizing hole 433 and the spray hole 311.

[0059] This application also discloses an automatic graded sprinkler irrigation method for vegetable seedlings.

[0061] S110, receives irrigation instructions;

[0062] Specifically, the irrigation command can be input via a host computer, voice command, or manual operation.

[0063] S120, based on irrigation instructions, retrieves irrigation water volume database; wherein, irrigation water volume database stores data on at least four types of irrigation water volume in order to match the water volume of seedlings that have not yet germinated, seedlings, large seedlings and mature seedlings, as well as the irrigation water volume data in between the four types;

[0066] Specifically, based on the current irrigation water volume of the seedlings, the start command is transmitted to the control motor 434. The control motor 434 drives the drive gear 435 to rotate, the drive gear 435 drives the driven gear 436 to rotate, the driven gear 436 drives the control tube 431 to rotate, and after the water output reaches the required level, the control motor stops, and then the water pump 320 is started. The water pump 320 drives water to spray onto the seedlings through the irrigation pipe 310 and the atomizing nozzle 432.

[0067] The implementation principle of the automatic graded sprinkler irrigation method for vegetable seedlings in this application embodiment is as follows: receiving an irrigation command, then retrieving the irrigation water reservoir, then obtaining the current growth status of the seedlings, then retrieving irrigation water from the irrigation water reservoir according to the seedling growth status, and driving the control motor 434 to start based on this irrigation water volume. The control motor 434 drives the control tube 431 to rotate through the drive gear 435 and the driven gear 436. The connectivity between the atomizing hole 433 and the spray hole 311 on the control tube 431 changes, and then the water pump 320 starts. The water pump 320 drives water to spray onto the seedlings through the sprinkler pipe 310 and the atomizing nozzle 432, thus completing the graded controlled irrigation of the seedlings.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
