Description

Technical Field

[0001] This utility model relates to the field of seagrass seedling technology, specifically to a convenient seagrass seedling auxiliary device. Background Technology

[0002] Seagrass cultivation and seedling production face numerous technical challenges, primarily stemming from the growth characteristics of seagrass and the complexity of the marine environment. Seagrass growth requires specific light, temperature, salinity, and water quality conditions, as well as suitable seabed topography and substrate. In the marine environment, these conditions are often difficult to control precisely, posing significant challenges to seagrass cultivation and seedling production.

[0003] While existing seaweed-assisted seedling raising devices have improved seedling raising efficiency to some extent, they may not be able to achieve uniform spraying of nutrient solution during the seedling raising process, thus affecting the seed germination rate and growth.

[0004] In summary, existing seaweed-assisted seedling raising devices may struggle to achieve uniform nutrient solution spraying, which affects seed germination rate and growth. This has become a pressing problem in the field, thus necessitating the development of a convenient seaweed-assisted seedling raising device. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a convenient seaweed seedling assistance device. Through the special structural design of the spraying components, it achieves uniform spraying of nutrient solution, thereby ensuring the growth and development of seaweed seeds, improving their germination rate, and thus realizing the function of seaweed seedling assistance.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A convenient seaweed-assisted seedling raising device includes a controller, an upper box and a lower box. The bottom of the upper box and the top of the lower box are detachably connected. A seedling raising door is hinged to one side of the lower box. Several casters are fixedly connected to the bottom of the lower box. A partition is fixedly connected to the inner wall of the upper box. The partition divides the interior of the upper box into a liquid storage chamber and a spraying chamber. The liquid storage chamber is filled with nutrient solution. A spraying component for spraying nutrient solution is provided at the bottom of the partition.

[0007] The top of the lower housing is fixedly connected to a first driving component and a second driving component. The input ends of the first driving component and the second driving component are both electrically connected to the output end of the controller. The output shafts of the first driving component and the second driving component are respectively fixedly connected to a first screw and a second screw on the same axis. The first screw and the second screw are respectively threaded with a first slide rod and a second slide rod.

[0008] A movable plate is slidably fitted on the first slide rod, and a limit rod is fixedly connected to the top of the movable plate. A limit groove is opened on the second slide rod, and the limit rod is slidably fitted with the limit groove. A sowing component for sowing seaweed seeds is provided at the bottom of the movable plate.

[0009] The inner side wall of the lower chamber is equipped with a seedling raising component for providing seedling sites for seagrass seeds.

[0010] The technical principles of the above solution are as follows:

[0011] Workers control the operation of the first and second drive components via a controller, causing the first and second screws to rotate. This, in turn, drives the first and second sliding rods to move left and right, and forward and backward, respectively. The first sliding rod moves the moving plate left and right together, while the second sliding rod moves the limiting rod forward and backward, which in turn moves the moving plate forward and backward. Once the moving plate is directly above the seedling assembly, the controller sows seaweed seeds through the seeding assembly. During this process, the controller also controls the spraying assembly to spray nutrient solution into the seedling assembly, thus initiating seaweed seedling cultivation.

[0012] The above approach has the following beneficial effects:

[0013] 1. This utility model achieves uniform spraying of nutrient solution through the special structural design of the spraying component, thereby ensuring the growth and development of seaweed seeds, improving their germination rate, and thus realizing the function of seaweed seedling assistance.

[0014] 2. This utility model uses a controller to control the operation of the first and second driving components, thereby adjusting the position of the moving plate and adjusting the position of the sowing component to ensure uniform sowing of seaweed seeds.

[0015] 3. With the universal wheels at the bottom of the lower box, the staff can easily move the device to the corresponding position, which improves the flexibility of the seedling raising device.

[0016] Furthermore, the spraying assembly includes a first telescopic member fixedly connected to an inner side wall of the upper housing. The input end of the first telescopic member is electrically connected to the output end of the controller. A slide plate is coaxially fixedly connected to the output shaft of the first telescopic member. A push-pull plate is coaxially fixedly connected to the side of the slide plate away from the output shaft of the first telescopic member. Several limiting blocks are fixedly connected at equal intervals at the bottom of the slide plate. A gear is provided below the slide plate. The gear and the limiting blocks are rotatably engaged. A connecting shaft is coaxially fixedly connected to the gear. A slider and an atomizing nozzle are fixedly connected to the connecting shaft. The atomizing nozzle communicates with the liquid storage chamber. An annular groove is opened at the bottom of the slide plate. The connecting shaft extends into the annular groove and slides with the annular groove.

[0017] A guide platform is fixedly connected to the other inner wall of the upper housing. A guide groove is opened inside the guide platform, and the push-pull plate extends into the guide groove and slides with the guide groove.

[0018] A limiting plate is fixedly connected to the inner side wall of the upper box. A sliding groove is opened on the limiting plate, and the slider slides in the sliding groove.

[0019] Beneficial effects: During the telescopic process of the first telescopic member, the moving distance and speed of the sliding plate can be precisely controlled, thereby achieving precise spraying of the atomizing nozzle and ensuring that each seedling raising point can obtain uniform nutrient solution. At the same time, the design of the atomizing nozzle can evenly spray the nutrient solution onto the seedling raising points, improving the utilization rate of the nutrient solution and reducing waste.

[0020] Furthermore, the shape of the guiding groove is U-shaped.

[0021] Beneficial effects: The U-shaped guiding groove has a clear shape, providing a clear moving path for the gas in the guiding groove. This clear guiding property enables the push-pull plate to stably transport the formed airflow under the atomizing nozzle during the push-pull process, disturbing the sprayed nutrient solution, thereby increasing its spraying range and making the spraying more uniform.

[0022] Furthermore, the shape of the slider is "I"-shaped.

[0023] Beneficial effects: The design of the "I"-shaped slider gives it a larger cross-sectional area, thereby improving its structural strength. This design can effectively resist external pressure and deformation, ensuring the stability of the slider during movement.

[0024] Furthermore, the seeding component includes a seed storage frame fixedly connected to the bottom of the moving plate. A seed storage opening is provided on one side of the seed storage frame, and a cover plate is hinged at the seed storage opening.

[0025] A number of telescopic cylinders are equidistantly connected to the bottom of the seed storage frame and a number of second telescopic members are equidistantly fixedly connected. The input end of the second telescopic member is electrically connected to the output end of the controller. The output shafts of the second telescopic members are fixedly connected to the lower parts of the adjacent telescopic cylinders. The bottoms of the telescopic cylinders are all connected to seeding tubes, and the bottoms of the seeding tubes are all connected to first solenoid valves. The input ends of the first solenoid valves are all electrically connected to the output end of the controller.

[0026] Beneficial effects: By controlling the second telescopic member and the first solenoid valve through the controller, the seeding position and quantity of the seeds can be precisely controlled, realizing the automation of the seeding process. This automated design reduces the complexity and errors of manual operation and improves the seeding efficiency.

[0027] Furthermore, the seedling raising component includes a rotating shaft rotatably connected to the inner side wall of the lower box body. A fixing plate is fixedly connected to the inner bottom wall of the lower box body. A third driving member is fixedly connected to one side of the fixing plate. The input end of the third driving member is electrically connected to the output end of the controller. The output shaft of the third driving member penetrates through the fixing plate and is coaxially fixedly connected to the rotating shaft.

[0028] Fixed frames are symmetrically fixedly connected to the rotating shaft, and a number of seedling raising frames are rotatably connected between adjacent fixed frames. The seedling raising frames are filled with seedling raising soil and water.

[0029] Beneficial effects: Driven by the third drive component, the rotating shaft can rotate the seedling frame, allowing seaweed seeds to receive more uniform light and nutrients during the seedling stage. Simultaneously, the structural design of the seedling frame being rotatably connected to the rotating shaft via a fixed frame achieves efficient space utilization. This design enables multiple seedling frames to be used simultaneously within a limited space, improving space utilization.

[0030] Furthermore, a second solenoid valve is connected to the partition. The input end of the second solenoid valve is electrically connected to the output end of the controller, and the second solenoid valve is connected to the atomizing nozzle.

[0031] Beneficial effects: Precise control of the second solenoid valve via the controller enables timed and quantitative spraying of the nutrient solution atomization. This precise control helps provide the seagrass seedlings with the necessary nutrients while avoiding waste and potential diseases caused by over-spraying.

[0032] Furthermore, a first adjusting block is threaded onto the first screw, and an LED light is fixedly connected to the side of the first adjusting block away from the first screw. The input end of the LED light is electrically connected to the output end of the controller.

[0033] Beneficial effects: When the first screw rotates, it causes the first adjusting block to move laterally, which in turn causes the LED light to move laterally. Workers can precisely adjust the position and brightness of the LED light through the controller, providing uniform and suitable lighting conditions for the seaweed seedlings. This helps promote photosynthesis, accelerates growth, and improves growth quality. At the same time, appropriate lighting conditions can also enhance the seaweed seedlings' resistance to adverse conditions and reduce the occurrence of diseases.

[0034] Furthermore, a second adjusting block is threaded onto the second screw, and a temperature and humidity sensor is fixedly connected to the side of the second adjusting block away from the second screw. The output end of the temperature and humidity sensor is electrically connected to the input end of the controller.

[0035] Beneficial effects: When the second screw rotates, it drives the second adjusting block to move laterally, which in turn drives the temperature and humidity sensor to move laterally. Operators can then precisely adjust the position of the temperature and humidity sensor via the controller. This adjustment method ensures that the temperature and humidity sensor is accurately positioned at a key location in the seedling area, thereby enabling real-time and accurate monitoring of the temperature and humidity in the seagrass seedlings' growth environment, providing effective data for adjusting their growth environment.

[0036] Furthermore, a feeding port is opened on the top of the upper box, and a feeding cover is detachably connected to the feeding port.

[0037] Beneficial effect: When it is necessary to add nutrient solution to the storage chamber, the staff can unscrew the feeding cap and add nutrient solution to the storage chamber through the feeding port.

[0038] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0045] The following detailed description illustrates the specific implementation method:

[0046] Example 1:

[0047] As attached Figure 1 、 and 2、 Figure 3 , Figure 4 and Figure 5As shown: A convenient seaweed-assisted seedling raising device includes a controller, an upper box 1 and a lower box 2. In this embodiment, the controller is preferably model 6ES7212-1AB23-0XB8. The bottom of the upper box 1 and the top of the lower box 2 are detachably connected by bolts. A seedling raising door 3 is hinged to one side of the lower box 2. Several universal wheels are fixedly connected to the bottom of the lower box 2 by bolts. A partition is integrally formed on the inner side wall of the upper box 1. The partition divides the interior of the upper box 1 into a liquid storage chamber and a spraying chamber. The liquid storage chamber is filled with nutrient solution. A spraying component for spraying nutrient solution is provided at the bottom of the partition.

[0048] The spraying assembly includes a first telescopic component bolted to the inner wall of the upper housing 1. The input end of the first telescopic component is electrically connected to the output end of the controller. In this embodiment, the first telescopic component is a first electric telescopic rod, preferably an MS3000B electric push rod. The output shaft of the first electric telescopic rod is coaxially bolted to a slide plate 4. A push-pull plate 5 is integrally formed coaxially on the left side of the slide plate 4. Several limiting blocks 6 are integrally formed at equal intervals at the bottom of the slide plate 4. A gear 7 is provided below the slide plate 4. The gear 7 and the limiting blocks 6 are rotatably engaged. A connecting shaft 8 is coaxially fixedly connected to the gear 7. An "I"-shaped slider 9 and an atomizing nozzle 10 are welded to the connecting shaft 8. The atomizing nozzle 10 is connected to the liquid storage chamber. An annular groove is opened at the bottom of the slide plate 4. The connecting shaft 8 extends into the annular groove and slides with the annular groove.

[0049] A guide platform 11 is welded to the other inner wall of the upper housing 1. A U-shaped guide groove is opened inside the guide platform 11. The push-pull plate 5 extends into the guide groove and slides laterally with the guide groove.

[0050] A limiting plate 12 is welded to the inner wall of the upper housing 1. A sliding groove is opened on the limiting plate 12, and the slider 9 slides in the sliding groove.

[0051] The top of the lower housing 2 is bolted to a first driving component and a second driving component. The input ends of the first driving component and the second driving component are both electrically connected to the output end of the controller. In this embodiment, the first driving component and the second driving component are respectively selected as a first stepper motor and a second stepper motor, and their models are preferably 86HN78-04-32Y. The output shaft of the first stepper motor and the output shaft of the second stepper motor are respectively bolted to a first screw 13 and a second screw 14. The first screw 13 and the second screw 14 are respectively threaded with a first slide rod 15 and a second slide rod 16.

[0052] A movable plate 17 is slidably fitted on the first slide rod 15. A limiting rod 18 is welded to the top of the movable plate 17. A limiting groove is opened on the second slide rod 16. The limiting rod 18 is slidably fitted with the limiting groove. A sowing component for sowing seaweed seeds is provided at the bottom of the movable plate 17.

[0053] The seeding assembly includes a seed storage frame 19 bolted to the bottom of the movable plate 17. The seed storage frame 19 has a seed storage opening on one side, and a cover plate 20 is hinged to the seed storage opening.

[0054] The bottom of the seed storage frame 19 is connected to several telescopic cylinders at equal intervals and several second telescopic components are fixedly connected to it by bolts at equal intervals. The input end of the second telescopic component is electrically connected to the output end of the controller. In this embodiment, the second telescopic component is a second electric telescopic rod, preferably an MS3000B electric push rod. The output shaft of the second electric telescopic rod is fixedly connected to the lower part of the adjacent telescopic cylinder by bolts. The bottom of each telescopic cylinder is connected to a seeding tube 21, and the bottom of each seeding tube 21 is connected to a first solenoid valve. The input end of each first solenoid valve is electrically connected to the output end of the controller. In this embodiment, the model of the first solenoid valve is preferably DMF-Z-20DC24V / 220V.

[0055] The inner wall of the lower box 2 is equipped with a seedling raising component for providing seedling raising sites for seagrass seeds.

[0056] The seedling assembly includes a rotating shaft 22 rotatably connected to the inner wall of the lower housing 2. A fixing plate 23 is integrally formed on the bottom wall of the lower housing 2. A third driving component is bolted to one side of the fixing plate 23. The input end of the third driving component is electrically connected to the output end of the controller. In this embodiment, the third driving component is a servo motor, preferably ECMA-C1-0604-RS. The output shaft of the servo motor passes through the fixing plate 23 and is bolted to the rotating shaft 22.

[0057] A fixed frame 24 is symmetrically welded on the rotating shaft 22, and several seedling frames 25 are rotatably connected between adjacent fixed frames 24. The seedling frames 25 are filled with seedling soil and water.

[0058] The specific implementation process is as follows: After the staff sets the sowing program of the controller, they first open the cover plate 20, place the cleaned and disinfected seaweed seeds with the seed coat removed into the seed storage frame 19, close the cover plate 20, and fix the upper box 1 and the lower box 2 together with bolts.

[0059] The staff simultaneously started the first stepper motor, the second stepper motor, the servo motor, and the second electric telescopic rod.

[0060] When the output shaft of the first stepper motor rotates, it drives the first screw 13 to rotate, which in turn drives the first slide rod 15 to move left and right. When the output shaft of the second stepper motor rotates, it drives the second screw 14 to rotate, which in turn drives the second slide rod 16 to move back and forth. During the left and right movement of the first slide rod 15, it drives the moving plate 17 to move left and right along with it. Due to the sliding engagement between the limiting rod 18 and the limiting groove, during the back and forth movement of the second slide rod 16, it drives the limiting rod 18 to move back and forth, which in turn drives the moving plate 17 to move back and forth, thereby adjusting the position of the moving plate 17.

[0061] The movable plate 17 first moves to one side of the seedling frame 25. Then, the controller activates the second electric telescopic rod, causing its output shaft to move downwards, which in turn moves the telescopic cylinder downwards, causing the sowing tube 21 to insert into the seedling soil. Since the two ends of the telescopic cylinder are connected to the seed storage frame 19 and the sowing tube 21 respectively, the seeds in the seed storage frame 19 will fall into the sowing tube 21. After the sowing tube 21 is inserted into the seedling soil, the controller controls the first solenoid valve to open, releasing the seaweed seeds from the sowing tube 21 into the seedling soil. Subsequently, the controller controls the output shaft of the second telescopic rod to retract, causing the telescopic cylinder to move upwards, while simultaneously closing the first solenoid valve, completing one sowing operation.

[0062] The controller controls the moving plate 17 to slowly move from one side of the seedling frame 25 to the other side of the seedling frame 25, and repeats the above-mentioned sowing operation during the movement until the moving plate 17 completes the movement.

[0063] In this embodiment, the time required to complete the sowing operation of one seedling frame 25 is 3 minutes. After the sowing operation of one seedling frame 25 is completed, the output shaft of the servo motor rotates, driving the rotating shaft 22 to rotate together. The rotating shaft 22 drives the fixed frame 24 to rotate, and the fixed frame 24 drives the seedling frame 25 to rotate together. In this embodiment, there are six seedling frames 25, and the initial position of one seedling frame 25 is located directly below the moving plate 17. The operator sets the rotation angle of the servo motor to 60° each time to ensure that there is always one seedling frame 25 directly below the moving plate 17, and sets the servo motor to stop for 3 minutes after each rotation to allow sufficient sowing time. After the output shaft of the servo motor rotates 60°, the controller controls the auxiliary seedling device to repeat the seaweed seed sowing operation until each seedling frame 25 has been sown.

[0064] After the seaweed seeds are sown, the controller activates the first electric telescopic rod, which reciprocates, causing the slide plate 4 to reciprocate. The slide plate 4 then drives the limit block 6 and the push-pull plate 5 to reciprocate together. At the same time, since the atomizing nozzle 10 is connected to the liquid storage chamber, the nutrient solution is released into the atomizing nozzle 10 and sprayed onto the seedling frame 25.

[0065] Since both gear 7 and limit block 6 are rotatably engaged, gear 7 is coaxially and fixedly engaged with connecting shaft 8, and connecting shaft 8 extends into the annular groove and slides with the annular groove, limit block 6 will drive gear 7 to rotate during reciprocating motion, and gear 7 will drive atomizing nozzle 10 to rotate.

[0066] The connecting shaft 8 will slide in the annular groove. At this time, since the connecting shaft 8 is welded with a slider 9 and the limiting plate 12 has a sliding groove, the slider 9 and the sliding groove slide together. As the connecting shaft 8 slides in the annular groove, under the limitation of the sliding groove, the connecting shaft 8 will drive the slider 9 to move back and forth, thereby driving the atomizing nozzle 10 to move back and forth.

[0067] During this process, the push-pull plate 5 is driven to reciprocate by the slide plate 4, and the push-pull plate 5 extends into the guide groove and slides with the guide groove, so that the push-pull plate 5 and the guide groove form a piston structure. When the push-pull plate 5 is pushed and pulled, the airflow generated will disturb the nutrient solution sprayed below the atomizing nozzle 10, making the spraying more uniform.

[0068] After the seaweed seeds are cultivated into seaweed seedlings, the staff can open the seedling door 3 and take out the cultivated seaweed seedlings.

[0069] When it is necessary to move the seedling raising device, thanks to the design of the casters, the staff can easily move the seedling raising device.

[0070] This invention achieves uniform spraying of nutrient solution through a special structural design of the spraying component, thereby ensuring the growth and development of seaweed seeds, improving their germination rate, and thus realizing the function of seaweed seedling assistance. Simultaneously, by controlling the operation of the first and second driving components through a controller, the position of the moving plate 17 is adjusted, which in turn adjusts the position of the sowing component, ensuring uniform sowing of seaweed seeds.

[0071] Example 2:

[0072] As attached Figure 2 As shown, the difference from Embodiment 1 is that a second solenoid valve 26 is connected to the partition. The input end of the second solenoid valve 26 is electrically connected to the output end of the controller. In this embodiment, the preferred model of the second solenoid valve 26 is DMF-Z-20DC24V / 220V. The second solenoid valve 26 is connected to the atomizing nozzle 10.

[0073] The specific implementation process is as follows: When it is necessary to control the amount of nutrient solution sprayed, the staff can control the opening and closing of the second solenoid valve 26 through the controller, thereby controlling the flow rate of nutrient solution entering the atomizing nozzle 10, reducing the consumption of nutrient solution and improving the utilization rate of nutrient solution.

[0074] Example 3:

[0075] As attached Figure 1 As shown, the difference from Embodiment 2 is that a first adjusting block 27 is threaded onto the first screw 13, and an LED light 28 is fixedly connected to the inner side of the first adjusting block 27 by a screw. The input terminal of the LED light 28 is electrically connected to the output terminal of the controller. In this embodiment, the LED light 28 is preferably a BCD-3020 model. A second adjusting block 29 is threaded onto the second screw 14, and a temperature and humidity sensor 30 is fixedly connected to the left side of the second adjusting block 29 by a screw. The output terminal of the temperature and humidity sensor 30 is electrically connected to the input terminal of the controller. In this embodiment, the temperature and humidity sensor 30 is preferably a LFH10A model.

[0076] The specific implementation process is as follows: The staff controls the brightness of the LED lights 28 through the controller to provide good lighting conditions for seaweed development, and monitors the temperature and humidity of the seaweed development environment through the temperature and humidity sensor 30. When the temperature and humidity conditions detected by the temperature and humidity sensor 30 are not conducive to seaweed development, the staff can promptly formulate a new plan for the seaweed development environment to provide better environmental conditions for seaweed development.

[0077] Example 4:

[0078] As attached Figure 1 and Figure 2 As shown, the difference from Embodiment 3 is that the top of the upper box 1 has a feeding port, and a feeding cover is detachably connected to the feeding port by threads.

[0079] The specific implementation process is as follows: When it is necessary to replenish the nutrient solution, the staff can unscrew the feeding cap and add the nutrient solution into the storage chamber through the feeding port.

[0080] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
