Description

Technical Field

[0001] The present invention belongs to the technical field of seedling raising equipment, and particularly relates to a combined seedling raising and planting device. Background Art

[0002] Soilless cultivation is a method of cultivating plants directly with nutrient solution without using soil. It uses nutrient solution to replace soil to provide oxygen, water and inorganic nutrients required by plant roots.

[0003] Currently, most soilless cultivations are carried out by opening holes in pipelines, and then flowing nutrient solution is introduced into the pipelines. Plant seedlings can be fixed in a seedling raising basket with sponges or solid particles and then placed into the holes of the pipelines. The seedlings are semi-immersed in the flowing solution for slow growth.

[0004] Since the number of seedlings to be cultivated each time is different and the lengths of sites in different places are different, for the currently used pipeline seedling raising and planting device, its equipment main body is fixedly connected to the pipeline. At this time, when it is desired to replace a pipeline with more or fewer holes, due to the inability to adjust the length of the equipment, different-length pipelines cannot be replaced as needed, resulting in low flexibility in use. Summary of the Invention

Detailed implementation manners

[0034] Reference to "embodiment" in this text means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] An embodiment of the present invention provides a combined seedling-growing planting device, as Figures 1-15As shown in the figure, the combined seedling-raising and planting device includes: a main housing 1 and a sub-housing 2. A telescopic housing 3 is fixedly installed between the main housing 1 and the sub-housing 2. The main housing 1, the sub-housing 2 and the telescopic housing 3 form a telescopic water storage tank. An outer attached reinforcing housing 4 is fixedly sleeved outside the sub-housing 2. The outer attached reinforcing housing 4 is slidably sleeved outside the main housing 1 and the telescopic housing 3, which is used to strengthen the connection strength between the main housing 1 and the sub-housing 2 and the support of the telescopic housing 3 after water injection. A return water support housing 5 is fixedly installed at the top of the main housing 1. The return water support housing 5 is communicated with the main housing 1 and is used for returning water. A support plate 6 is fixedly installed at the top of the sub-housing 2. The support plate 6 and the return water support housing 5 are arranged in parallel. The return water support housing 5 and the support plate 6 are respectively located on both sides of the outer attached reinforcing housing 4. A plurality of first support plates 7 and second support plates 8 are respectively fixedly installed on the sides of the return water support housing 5 and the support plate 6 close to each other. The first support plates 7 and the second support plates 8 are arranged in pairs. The tops of the paired first support plates 7 and second support plates 8 are respectively fixedly installed with sub-pipe seats 9 and main pipe seats 10 for placing the seedling-raising water pipes 11. The seedling-raising water pipes 11 can be placed with seedling-raising planting baskets 12 for raising seedlings. One end of the seedling-raising water pipe 11 drains water to the return water support housing 5, and the other end receives the water inlet of the water storage tank. Among them, the telescopic water storage tank can control the distance between the return water support housing 5 and the support plate 6, and then change the distance between the sub-pipe seat 9 and the main pipe seat 10, so as to place the seedling-raising water pipes 11 of different lengths and meet the needs of placing different numbers of seedling-raising planting baskets 12.

[0036] In this embodiment, first, according to the actual number of seedlings to be cultivated and the site conditions, by adjusting the telescopic length of the telescopic housing 3 between the main housing 1 and the sub-housing 2, the total volume of the water storage tank and the distance between the return water support housing 5 and the support plate 6 are controlled. This adjustment process can flexibly adapt to the seedling-raising water pipes 11 of different lengths, ensuring that the device can adapt to diverse seedling-raising needs.

[0037] Next, the seedling-raising water pipes 11 are placed on the paired first support plates 7 and second support plates 8 in a predetermined order and are respectively erected by the sub-pipe seats 9 and the main pipe seats 10. One end of the seedling-raising water pipe 11 is connected to the return water support housing 5 so as to return the used nutrient solution to the water storage tank, and the other end receives the fresh nutrient solution from the water storage tank. This design not only ensures the recycling of the nutrient solution but also ensures that each seedling-raising water pipe 11 can obtain uniform and sufficient nutrient supply.

[0038] Finally, the seedling-raising planting baskets 12 are placed in the seedling-raising water pipes 11 and filled with an appropriate amount of culture medium or substrate so that the seedlings can grow stably. By adjusting the length of the seedling-raising water pipes 11 and the number of the seedling-raising planting baskets 12, it is easy to meet the cultivation needs from a small number to a large number of seedlings.

[0039] This combined seedling cultivation and planting device significantly improves the flexibility and adaptability of the device by introducing a retractable water storage tank design. Users can easily adjust the length and height of the water storage tank according to actual needs, so as to adapt to different lengths of seedling cultivation water pipes 11 and different numbers of seedling cultivation and planting baskets 12. This design not only saves space but also reduces equipment costs, making soilless cultivation more economical and efficient.

[0040] In addition, the device also strengthens the connection strength between the main housing 1 and the auxiliary housing 2 through the sliding sleeve design of the externally attached reinforcing shell 4, and provides effective support for the telescopic shell 3. This design not only improves the overall stability of the device but also ensures safety and reliability during use. At the same time, the parallel arrangement of the return water support shell 5 and the support plate 6 and the paired design of the first support plate 7 and the second support plate 8 provide great convenience for the placement and fixation of the seedling cultivation water pipe 11.

[0041] Finally, this combined seedling cultivation and planting device also pays attention to the recycling and uniform supply of nutrient solution. By connecting one end of the seedling cultivation water pipe 11 to the return water support shell 5 and receiving fresh nutrient solution from the water storage tank at the other end, a closed-loop circulation of the nutrient solution is achieved. This design not only improves the utilization efficiency of the nutrient solution but also ensures that each seedling cultivation water pipe 11 can obtain uniform and sufficient nutrient supply, thus promoting the healthy growth and development of the seedlings.

[0042] In a further preferred embodiment of the present invention, support legs 13 are fixedly installed at the bottom of the main housing 1, and moving wheels 14 are fixedly installed at the bottom of the auxiliary housing 2, which are used to control the expansion and contraction of the telescopic shell 3 when the auxiliary housing 2 and the externally attached reinforcing shell 4 slide, so as to control the internal volume of the water storage tank.

[0043] In this embodiment, support legs 13 are fixedly installed at the bottom of the main housing 1. These support legs 13 not only provide stable support but also ensure the balance of the device in a stationary state. To further ensure stability, the support legs 13 can be fixed to the ground with bolts. And moving wheels 14 are fixedly installed at the bottom of the auxiliary housing 2. The design of these moving wheels 14 enables the auxiliary housing 2 to adjust the expansion and contraction state of the telescopic shell 3 by moving during the sliding process of the externally attached reinforcing shell 4, so as to precisely control the internal volume of the water storage tank.

[0044] In actual operation, users can push or pull the auxiliary housing 2, taking advantage of the convenience of the moving wheels 14, to make the auxiliary housing 2 slide relative to the main housing 1. This sliding action will drive the telescopic shell 3 to expand and contract, thereby changing the total volume of the water storage tank. Users can flexibly adjust the volume of the water storage tank according to the number of seedlings to be cultivated and the demand for nutrient solution to meet different scales of seedling cultivation tasks.

[0045] In addition, the design of the moving wheels 14 also makes the device more stable and safe when adjusting the volume. Traditional devices may need to lift or move heavy components when adjusting the volume, which not only increases the operation difficulty but also may pose safety hazards. However, through the sliding design of the moving wheels 14, this device achieves easy and stable volume adjustment, avoiding potential safety risks.

[0046] In a further preferred embodiment of the present invention, a shaft seat 15 and a motor 16 are fixedly installed at the bottom of the main housing 1, a moving block 17 is fixedly installed at the bottom of the outer attached reinforcing shell 4, an adjusting screw rod 18 is rotatably installed on the shaft seat 15, one end of the adjusting screw rod 18 is fixedly connected to the output shaft of the motor 16, and the adjusting screw rod 18 threadedly penetrates through the moving block 17 to drive the movement of the outer attached reinforcing shell 4 and the secondary housing 2 and the telescopic of the telescopic shell 3, thereby controlling the internal volume of the water storage tank.

[0047] In this embodiment, a shaft seat 15 and a motor 16 are fixedly installed at the bottom of the main housing 1. An adjusting screw rod 18 is rotatably installed on the shaft seat 15, and one end of the adjusting screw rod 18 is fixedly connected to the output shaft of the motor 16. At the same time, a moving block 17 is fixedly installed at the bottom of the outer attached reinforcing shell 4, and the adjusting screw rod 18 threadedly penetrates through the moving block 17. When the motor 16 is started, its output shaft will drive the adjusting screw rod 18 to rotate, and then drive the moving block 17 to move axially along the adjusting screw rod 18 through screw transmission. This movement will drive the outer attached reinforcing shell 4 and the secondary housing 2 to move together, thereby controlling the telescopic state of the telescopic shell 3 and precisely adjusting the internal volume of the water storage tank.

[0048] In a further preferred embodiment of the present invention, placing holes 19 are formed in the seedling-growing water pipe 11 for placing the seedling-growing planting baskets 12. The upper part of the placing seedling-growing planting basket 12 has a rim, and the diameter of the rim is larger than the aperture of the placing hole 19.

[0049] In this embodiment, placing holes 19 are formed in the seedling-growing water pipe 11, and the size and shape of these placing holes 19 ensure that the seedling-growing planting baskets 12 can be stably placed. At the same time, the upper part of the seedling-growing planting basket 12 is designed with a rim, and the diameter of the rim is larger than the aperture of the placing hole 19, so as to provide additional support and stability during placement, preventing the seedling-growing planting baskets 12 from slipping or tilting during the flow of nutrient solution or operation.

[0050] In actual operation, the user only needs to align the rim of the seedling-growing planting basket 12 with the placing hole 19 and then gently place it. Since the diameter of the rim is larger than the aperture of the placing hole 19, the seedling-growing planting basket 12 will be firmly stuck in the placing hole 19 without additional fixing measures.

[0051] In a further preferred embodiment of the present invention, water inlet connectors 20 and drain connectors 21 are respectively detachably sleeved at both ends of the seedling-raising water pipe 11. The water inlet connectors 20 and the drain connectors 21 are both in watertight connection with the seedling-raising water pipe 11. A plurality of connecting pipes 22 with valves are fixedly installed on the support plate 6. The number of the connecting pipes 22 is equal to the number of the seedling-raising water pipes 11, the water inlet connectors 20 and the drain connectors 21. The connecting pipes 22 are docked with the water inlet connectors 20 at corresponding positions. An external thread of the docking position of the connecting pipe 22 and the water inlet connector 20 is sleeved with a gear screw cylinder 23. A water pump 24 is arranged in the secondary housing 2. A liquid supply pipe 25 is installed at the drainage end of the water pump 24. The liquid supply pipe 25 extends to the side of the support plate 6 and is fixedly connected with a plurality of connecting pipes 22, for pumping the aqueous solution into the seedling-raising water pipe 11 for the plants in the seedling-raising planting basket 12 to absorb.

[0052] In this embodiment, water inlet connectors 20 and drain connectors 21 are respectively detachably sleeved at both ends of the seedling-raising water pipe 11. A watertight connection is achieved between these two connectors and the seedling-raising water pipe 11, ensuring the stability and safety of the nutrient solution during transportation. At the same time, a plurality of connecting pipes 22 with valves are fixedly installed on the support plate 6. The number of these connecting pipes 22 is equal to the number of the seedling-raising water pipes 11, the water inlet connectors 20 and the drain connectors 21, so as to achieve one-to-one precise docking.

[0053] In actual operation, the user only needs to dock the water inlet connector 20 with the connecting pipe 22 at the corresponding position, and externally thread the gear screw cylinder 23 at the docking position to fix the connection. This design not only simplifies the connection process but also improves the firmness and stability of the connection. At the same time, a water pump 24 is arranged in the secondary housing 2, and a liquid supply pipe 25 is installed at its drainage end. The liquid supply pipe 25 extends to the side of the support plate 6 and is fixedly connected with a plurality of connecting pipes 22. When the water pump 24 is started, it will draw the nutrient solution from the storage tank and pump the nutrient solution into the seedling-raising water pipe 11 through the liquid supply pipe 25 and the connecting pipes 22 for the plants in the seedling-raising planting basket 12 to absorb.

[0054] In a further preferred embodiment of the present invention, a plurality of water receiving pipes 26 are fixedly installed on the return water support shell 5. Drain pipes 27 are fixedly installed on a plurality of the drain connectors 21. The liquid discharge end of the drain pipe 27 is inserted into the corresponding water receiving pipe 26, for returning the aqueous solution in the seedling-raising water pipe 11 into the main housing 1 through the return water support shell 5.

[0055] In this embodiment, a plurality of water receiving pipes 26 are fixedly installed on the return water support shell 5, and the positions and quantities of these water receiving pipes 26 match those of the drain joints 21. At the same time, a drain pipe 27 is fixedly installed on each drain joint 21, and the liquid discharge end of the drain pipe 27 is cleverly inserted into the corresponding water receiving pipe 26. This design enables the aqueous solution in the seedling-growing water pipe 11 to flow smoothly through the drain pipe 27 into the water receiving pipe 26 when being discharged, and finally flow back into the main housing 1, realizing the recycling and saving of the aqueous solution.

[0056] In actual operation, when the aqueous solution in the seedling-growing water pipe 11 needs to be discharged, the aqueous solution will flow along the drain pipe 27 into the water receiving pipe 26. Since the water receiving pipe 26 is connected to the inside of the return water support shell 5 and the main housing 1, the aqueous solution will finally flow back into the water storage tank in the main housing 1 for subsequent seedling growing. This design not only simplifies the operation process, but also improves the utilization rate and saving effect of the aqueous solution.

[0057] In a further preferred embodiment of the present invention, a plurality of pipe placement positioning plates 28 are fixedly installed on the return water support shell 5. The plurality of pipe placement positioning plates 28 are staggered above the plurality of water receiving pipes 26. A positioning notch 29 is provided on each of the plurality of pipe placement positioning plates 28 for the insertion and positioning of the drain pipe 27, and the width of the positioning notch 29 is equal to the diameter of the drain pipe 27.

[0058] In this embodiment, a plurality of pipe placement positioning plates 28 are fixedly installed on the return water support shell 5. The plurality of pipe placement positioning plates 28 are staggered above the plurality of water receiving pipes 26. At the same time, a positioning notch 29 is provided on each pipe placement positioning plate 28, and the width of these positioning notches 29 is equal to the diameter of the drain pipe 27, enabling the drain pipe 27 to be accurately inserted and fixed in the positioning notch 29.

[0059] In actual operation, when placing the seedling-growing water pipe 11, the user only needs to align the liquid discharge end of the drain pipe 27 with the corresponding water receiving pipe 26 and insert it into the positioning notch 29 on the pipe placement positioning plate 28. Since the width of the positioning notch 29 is equal to the diameter of the drain pipe 27, the drain pipe 27 can be stably fixed in the positioning notch 29, avoiding problems such as unsmooth backflow or leakage caused by shaking or falling off. This design not only simplifies the positioning and fixing process of the drain pipe 27, but also improves the stability and safety of the entire backflow system.

[0060] In a further preferred embodiment of the present invention, a filter screen 30 is fixedly installed in the main housing 1 for filtering the refluxed aqueous solution. A cleaning port is provided on the side of the main housing 1, and a closing plate 31 for blocking the cleaning port is detachably installed on the side of the main housing 1 by bolts.

[0061] In this embodiment, the filter screen 30 is fixedly installed inside the main housing 1 at a key position in the reflux path, for filtering the refluxed aqueous solution to remove impurities and particulate matters therein. In addition, a cleaning port is provided on the side of the main housing 1, and this cleaning port is designed to facilitate the user to clean and maintain the filter screen 30. In order to ensure the sealing and detachable property of the cleaning port, a bolt connection method is adopted, and a closing plate 31 is installed to block the cleaning port.

[0062] In actual operation, when it is necessary to clean or replace the filter screen 30, the user only needs to unscrew the bolts on the closing plate 31 and remove the closing plate 31, then can conveniently access the filter screen 30. Then, the user can clean or replace the filter screen 30 to ensure its filtering effect. After cleaning, reinstall the closing plate 31 onto the main housing 1 through bolts, and the entire maintenance process can be completed.

[0063] In a further preferred embodiment of the present invention, a replenishing pipe 32 with a valve is installed at the top of the main housing 1, and a sewage discharge pipe 33 with a valve is installed at the bottom of the side of the main housing 1.

[0064] In this embodiment, a replenishing pipe 32 with a valve is installed at the top of the main housing 1. This design enables the user to conveniently add new aqueous solution or nutrient solution into the main housing 1 through the replenishing pipe 32 to meet the requirements during the seedling raising process. At the same time, a sewage discharge pipe 33 with a valve is installed at the bottom of the side of the main housing 1. This design enables the user to regularly discharge the sewage or waste liquid in the main housing 1 to keep the inside of the main housing 1 clean and hygienic.

[0065] In actual operation, when it is necessary to add aqueous solution or nutrient solution into the main housing 1, the user only needs to open the valve on the replenishing pipe 32 and inject the required aqueous solution or nutrient solution into the main housing 1 through the replenishing pipe 32. Similarly, when it is necessary to discharge the sewage or waste liquid in the main housing 1, the user only needs to open the valve on the sewage discharge pipe 33 and discharge the sewage or waste liquid through the sewage discharge pipe 33. These two designs not only simplify the operation process but also improve the work efficiency.

[0066] In a further preferred embodiment of the present invention, the seedling planting basket 12 is integrally in a frustum structure, with its diameter gradually decreasing from top to bottom. The seedling planting basket 12 is equally divided into two half baskets, and the two half baskets are detachably connected. The top of the seedling planting basket 12 is a seedling placing port 34, and the bottom is a root system port 35. A plurality of water permeable ports 36 are provided on the periphery of the seedling planting basket 12. Inside one of the half baskets, there is a positioning marking point 37 for automated equipment to identify. On this half basket, there is also a grasping suction cup and an information reading and storing module 38, which is in a sheet structure and has an identification pattern on its surface for information reading or storing to facilitate digital management.

[0067] In this embodiment, positioning identification points 37 and grabbing suction cups and information reading and storage modules 38 are provided on the front and rear halves of the basket. The grabbing suction cups and information reading and storage modules 38 can be provided with patterns on the surface, such as bar codes, two-dimensional codes, texts, etc., or erasable chips can be pre-installed inside the basket during die-casting for information reading or storage, which is convenient for digital management; multiple positioning identification points 37 are provided, and different patterns are used, so that during assembly line production and planting, the equipment machinery can perform image recognition to determine the direction and position of the planting basket, and adjust the manipulator accordingly to accurately locate, grab and place it.

[0068] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0069] In another embodiment of the present invention, the two halves of the basket body are detachably connected by mortise and tenon joints or the two halves of the basket body are fixedly mounted with mounting blocks 39, and magnets 40 are fixedly mounted on the mounting blocks 39. The two corresponding magnets 40 are attracted to each other so that the two halves of the basket body can be detachably connected for placing or removing the seedlings with sponges.

[0070] In this embodiment, the seedling planting basket 12 is produced by die-casting in two halves, front and rear halves, and the die-casting mold allows the basket body to form mortise and tenon joints at the same positions on the butt joint surfaces of the two halves, or magnets are directly used instead of the mortise and tenon joints.

[0071] When in use, the corresponding two sides are joined together by mortise and tenon joints or magnets; when separated, the seedlings can be placed in one half of the planting basket conveniently through mechanization and automation, and the other half can be closed after placement to complete the planting process of the seedling planting basket, thus solving the problem that the seedling planting has long relied on manual operation, which is slow and costly.

[0072] When removing the seedlings, most of the current methods use a round sponge with a mouth opened and fixed on the seedlings, and then the sponge and the seedlings are stuffed into the seedling planting basket 12. When taking out the seedlings, the sponge is deeply sunken and difficult to take out. At this time, the seedlings are easily broken, and the seedlings have a well-developed root system during growth, which passes through the complex holes of the seedling planting basket 12, further increasing the difficulty of taking out and making it easier to damage the seedlings.

[0073] In this solution, the seedling planting basket 12 is divided into two halves, which is convenient for disassembly. When removing the seedlings and the sponge, only the two halves need to be separated, which greatly reduces the problem of damaging the seedlings.

[0074] In another embodiment of the present invention, the combined seedling raising and planting device further includes a plurality of synchronous locking mechanisms. The synchronous locking mechanism includes assembly holes 41 opened on both sides of the main pipe seat 10. Driving screw cylinders 42 are rotatably installed in both of the two assembly holes 41. Resistance screw rods 43 are threadedly installed in both of the two driving screw cylinders 42. When the two driving screw cylinders 42 drive the two resistance screw rods 43 to approach each other, they respectively abut against both sides of the seedling raising water pipe 11 for fixing the seedling raising water pipe 11. Rectangular through holes 44 are opened on both of the two resistance screw rods 43. Support frames 45 are fixedly installed on both sides of the main pipe seat 10. Rectangular guide rods 46 are fixedly installed on both of the two support frames 45. The two rectangular guide rods 46 are respectively inserted into the two rectangular through holes 44 for guiding when the driving screw cylinder 42 rotates to drive the resistance screw rod 43 to move. An assembly plate 47 is fixedly installed on the second supporting plate 8. A synchronous shaft 48 is rotatably installed on the assembly plate 47. Chain wheels one 49 are fixedly sleeved on both ends of the synchronous shaft 48 and on both of the two driving screw cylinders 42. The same chain one 50 is sleeved on the corresponding two chain wheels one 49 so that the synchronous shaft 48 can drive the two driving screw cylinders 42 to rotate simultaneously, thereby driving the two resistance screw rods 43 to approach or move away from each other.

[0075] In this embodiment, a plurality of synchronous locking mechanisms are introduced to firmly fix the seedling raising water pipe 11. Specifically, the synchronous locking mechanism includes assembly holes 41 opened on both sides of the main pipe seat 10, and driving screw cylinders 42 are rotatably installed in the assembly holes 41. Resistance screw rods 43 are threadedly installed in the driving screw cylinders 42. When the two driving screw cylinders 42 rotate synchronously, they will drive the two resistance screw rods 43 to approach or move away from each other. To ensure the stability of the movement of the resistance screw rod 43, rectangular through holes 44 are opened on the resistance screw rod 43, and support frames 45 are fixedly installed on both sides of the main pipe seat 10. Rectangular guide rods 46 are fixedly installed on the support frames 45, and the rectangular guide rods 46 are inserted into the rectangular through holes 44 to play a guiding role. In addition, an assembly plate 47 is fixedly installed on the second supporting plate 8. A synchronous shaft 48 is rotatably installed on the assembly plate 47. Chain wheels one 49 are fixedly sleeved on the synchronous shaft 48 and on both of the two driving screw cylinders 42, and are connected by a chain one 50 to realize the function of the synchronous shaft 48 driving the two driving screw cylinders 42 to rotate simultaneously.

[0076] In actual operation, when it is necessary to fix the seedling raising water pipe 11, only need to rotate the synchronous shaft 48. The synchronous shaft 48 drives the two driving screw cylinders 42 to rotate synchronously through the chain one 50, and then drives the two resistance screw rods 43 to approach each other and abut against both sides of the seedling raising water pipe 11, realizing the firm fixation of the seedling raising water pipe 11. When it is necessary to release the seedling raising water pipe 11, the user rotates the synchronous shaft 48 in the reverse direction, and the two resistance screw rods 43 can be made to move away from each other, thereby releasing the seedling raising water pipe 11.

[0077] The introduction of the synchronous locking mechanism improves the fixing effect and stability of the seedling water pipe 11. The two abutting screws 43 are close to each other and abut on both sides of the seedling water pipe 11, so that the seedling water pipe 11 is fixed in all directions, avoiding the problem of the seedling water pipe 11 falling off or shifting due to shaking or external force. This design not only improves the stability and safety of the seedling raising process, but also ensures the accuracy and consistency of the seedling raising effect.

[0078] In another embodiment of the present invention, a power conversion shaft 51 is rotatably mounted on the support plate 6, and the power conversion shaft 51 is located above the second supporting plate 8 at a corresponding position. A bevel gear 52 is fixedly mounted on the power conversion shaft 51 and the synchronous shaft 48, and the two bevel gears 52 are meshed with each other so that the power conversion shaft 51 drives the synchronous shaft 48 to rotate.

[0079] In this embodiment, the power conversion shaft 51 is rotatably mounted on the support plate 6 and is located above the second support plate 8 at the corresponding position. Bevel gears 52 are fixedly mounted on the power conversion shaft 51 and the synchronization shaft 48, and the two bevel gears 52 are meshed. Therefore, when the power conversion shaft 51 rotates, it drives the synchronization shaft 48 to rotate synchronously through the transmission effect of the bevel gear 52.

[0080] In actual operation, the power conversion shaft 51 can be driven to rotate. After the power conversion shaft 51 rotates, the bevel gear 52 on it will drive the bevel gear 52 on the synchronization shaft 48 to rotate synchronously, thereby realizing the rotation of the synchronization shaft 48. After the synchronization shaft 48 rotates, the two driving screw barrels 42 will be driven to rotate synchronously through the transmission effect of the chain 1 50, thereby realizing the synchronous movement of the two abutting screws 43, and completing the fixing or releasing operation of the seedling water pipe 11.

[0081] In another embodiment of the present invention, a driven gear 53 is fixedly sleeved on the power conversion shaft 51, and a driving shaft 54 ​​rotatably mounted on the support plate 6 is provided between the corresponding power conversion shaft 51 and the docking pipe 22, and a half tooth 55 is fixedly mounted on the driving shaft 54, and the half tooth 55 alternately meshes with the gear screw barrel 23 and the driven gear 53, so that after the seedling water pipe 11 is placed, the driven gear 53 is first driven to rotate, so that the interference screw 43 fixes the seedling water pipe 11, and then the gear screw barrel 23 is driven to rotate, so that the gear screw barrel 23 slides out of the thread on the docking pipe 22 and is threadedly sleeved on the water inlet joint 20, thereby realizing the connection between the water inlet joint 20 and the docking pipe 22.

[0082] In this embodiment, a driven gear 53 is fixedly sleeved on the power conversion shaft 51, and a drive shaft 54 ​​rotatably mounted on the support plate 6 is provided between the power conversion shaft 51 and the butt joint 22. A half tooth 55 is fixedly mounted on the drive shaft 54, and the half tooth 55 can alternately mesh with the gear screw barrel 23 and the driven gear 53. Therefore, after placing the seedling water pipe 11, the drive shaft 54 ​​can be rotated first, so that the half tooth 55 first meshes with the driven gear 53 and drives it to rotate, and then through the transmission effect of the power conversion shaft 51 and the bevel gear 52, the synchronous shaft 48 is driven to rotate, so that the abutment screw 43 fixes the seedling water pipe 11. Subsequently, the half tooth 55 meshes with the gear screw barrel 23 and drives it to rotate, so that the gear screw barrel 23 is threadedly sleeved on the water inlet joint 20 after sliding out of the thread on the butt joint 22, thereby completing the connection between the water inlet joint 20 and the butt joint 22.

[0083] The introduction of the driven gear 53, the driving shaft 54 ​​and the half teeth 55 enables the power conversion shaft 51 to not only drive the synchronous shaft 48 to rotate to fix the seedling water pipe 11, but also to achieve the connection between the water inlet joint 20 and the butt joint 22. This design not only simplifies the operation process, reduces the difficulty of operation, but also improves work efficiency. The user only needs to perform one driving operation to complete the fixing of the seedling water pipe 11 and the connection of the water inlet joint 20, which greatly saves time and energy.

[0084] In another embodiment of the present invention, a plurality of the synchronous locking mechanisms have a sprocket 2 56 fixedly sleeved on their drive shafts 54, and a same chain 2 57 is sleeved on the plurality of the sprockets 2 56. A plurality of chain fall shafts 58 are installed on the side of the support plate 6 for tightening the chain 2 57. A handwheel 59 is fixedly installed on one end of one of the drive shafts 54. The plurality of the synchronous locking mechanisms operate synchronously for synchronously connecting a plurality of seedling water pipes 11 at the same time.

[0085] In this embodiment, sprockets 2 56 are fixedly mounted on the driving shafts 54 of the multiple synchronous locking mechanisms, and the same chain 2 57 is mounted on these sprockets 2 56. In order to keep the chain 2 57 in a tensioned state, multiple chain shafts 58 are installed on the side of the support plate 6. In addition, a hand wheel 59 is fixedly mounted on one end of one of the driving shafts 54 so that the user can drive multiple synchronous locking mechanisms to operate synchronously by turning the hand wheel 59. Therefore, when it is necessary to fix and connect multiple seedling water pipes 11 at the same time, the user only needs to turn the hand wheel 59, and the multiple driving shafts 54 can be rotated synchronously through the transmission effect of the chain 2 57, thereby driving multiple synchronous locking mechanisms to operate synchronously, thereby realizing the synchronous fixing and connection of multiple seedling water pipes 11.

[0086] The introduction of the second sprocket 56, the second chain 57, the inverted chain shaft 58 and the handwheel 59 enables multiple synchronous locking mechanisms to operate synchronously, thereby realizing the synchronous fixation and connection of multiple seedling-growing water pipes 11. This design not only simplifies the operation process, reduces the operation difficulty, but also greatly improves the work efficiency. The user only needs to rotate the handwheel 59 to complete the synchronous processing of multiple seedling-growing water pipes 11, which greatly saves time and energy.

[0087] In another embodiment of the present invention, a plurality of air ports 60 are formed on the outer attached reinforcing shell 4, and the positions of the plurality of air ports 60 correspond to the telescopic shell 3, and are used to balance the air pressure between the main housing 1 and the secondary housing 2 when changing the distance and the outer side of the telescopic shell 3.

[0088] In this embodiment, the air ports 60 are formed on the outer attached reinforcing shell 4 and the positions correspond to the telescopic shell 3. When the distance between the main housing 1 and the secondary housing 2 changes, such as the telescopic movement of the telescopic shell 3 caused by the placement or removal of the seedling-growing water pipe 11, these air ports 60 can allow air to freely enter and exit, so as to balance the air pressure between the main housing 1 and the secondary housing 2 and the outer side of the telescopic shell 3. This design aims to ensure that the telescopic shell 3 will not be subject to unnecessary resistance or damage due to air pressure differences during the telescopic process.

[0089] In summary, compared with the related art, the present device controls the total volume of the water storage tank and the distance between the return water support shell 5 and the support plate 6 by adjusting the telescopic length of the telescopic shell 3 between the main housing 1 and the secondary housing 2, and can flexibly adapt to different lengths of seedling-growing water pipes 11, ensuring that the device can meet diverse seedling-growing needs.
