DETAILED DESCRIPTION

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The embodiment of the present invention provides a combined seedling planting device, such as Figure 1-15As shown, the combined seedling planting device includes: a main shell 1 and a sub-shell 2, a telescopic shell 3 is fixedly installed between the main shell 1 and the sub-shell 2, and the main shell 1, the sub-shell 2 and the telescopic shell 3 constitute a telescopic water tank; the sub-shell 2 is fixedly sleeved with an external additional strong shell 4, and the external additional strong shell 4 is slidably sleeved outside the main shell 1 and the telescopic shell 3, and is used to strengthen the connection strength between the main shell 1 and the sub-shell 2 and the support of the telescopic shell 3 after water injection; a return water support shell 5 is fixedly installed on the top of the main shell 1, and the return water support shell 5 is connected with the main shell 1 and is used for return water introduction, and a support plate 6 is fixedly installed on the top of the sub-shell 2, and the support plate 6 and the return water support shell 5 are arranged in parallel, and the return water support shell 5 and the support plate 6 are respectively located on both sides of the external additional strong shell 4 ; A plurality of first supporting plates 7 and second supporting plates 8 are fixedly installed on the side where the return water support shell 5 and the support plate 6 are close to each other, and the first supporting plates 7 and the second supporting plates 8 are arranged in pairs, and the tops of the first supporting plates 7 and the second supporting plates 8 arranged in pairs are fixedly installed with auxiliary pipe seats 9 and main pipe seats 10, which are used to place seedling water pipes 11, and seedling planting baskets 12 can be placed on the seedling water pipes 11 for seedling cultivation. One end of the seedling water pipe 11 discharges water to the return water support shell 5, and the other end receives water from the water storage tank; wherein the retractable water storage tank can control the spacing between the return water support shell 5 and the support plate 6, thereby changing the spacing between the auxiliary pipe seats 9 and the main pipe seats 10, which is used to place seedling water pipes 11 of different lengths to meet the needs of placing different numbers of seedling planting baskets 12.

[0021] In this embodiment, first, according to the actual number of seedlings to be cultivated and the site conditions, the total volume of the water storage tank and the distance between the return water support shell 5 and the support plate 6 are controlled by adjusting the telescopic length of the telescopic shell 3 between the main shell 1 and the auxiliary shell 2. This adjustment process can flexibly adapt to seedling water pipes 11 of different lengths, ensuring that the device can adapt to diverse seedling cultivation needs.

[0022] Next, the seedling water pipe 11 is placed on the paired first support plate 7 and second support plate 8 in a predetermined order, and is respectively installed through the auxiliary pipe seat 9 and the main pipe seat 10. One end of the seedling water pipe 11 is connected to the return support shell 5 so that the used nutrient solution can flow back to the water storage tank, and the other end receives 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 water pipe 11 can obtain a uniform and sufficient supply of nutrients.

[0023] Finally, the seedling planting basket 12 is placed in the seedling water pipe 11 and filled with an appropriate amount of culture medium or matrix so that the seedlings can grow stably. By adjusting the length of the seedling water pipe 11 and the number of seedling planting baskets 12, the cultivation needs of a small amount to a large amount of seedlings can be easily met.

[0024] The combined seedling planting device significantly improves the flexibility and adaptability of the device by introducing a retractable water tank design. Users can easily adjust the length and height of the water tank according to actual needs to adapt to seedling water pipes 11 of different lengths and different numbers of seedling planting baskets 12. This design not only saves space, but also reduces equipment costs, making soilless cultivation more economical and efficient.

[0025] 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 additional reinforcement 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 water pipe 11.

[0026] Finally, the combined seedling planting device also focuses on the recycling and uniform supply of nutrient solution. By connecting one end of the seedling water pipe 11 to the return water support shell 5 and the other end receiving fresh nutrient solution from the water storage tank, 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 water pipe 11 can obtain a uniform and sufficient supply of nutrients, thereby promoting the healthy growth and development of the seedlings.

[0027] In a further preferred embodiment of the present invention, a support leg 13 is fixedly installed on the bottom of the main shell 1, and a moving wheel 14 is fixedly installed on the bottom of the auxiliary shell 2, which is used to control the extension and retraction of the telescopic shell 3 when the auxiliary shell 2 and the external reinforcement shell 4 slide, thereby controlling the internal volume of the water tank.

[0028] 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 static state. To further ensure stability, the support legs 13 can be fixed to the ground with bolts. 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 telescopic state of the telescopic housing 3 by moving during the sliding process of the external reinforcement housing 4, thereby accurately controlling the internal volume of the water tank.

[0029] In actual operation, the user can push or pull the auxiliary housing 2 and use 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 housing 3 to expand and contract, thereby changing the total volume of the water tank. The user can flexibly adjust the volume of the water tank according to the number of seedlings to be cultivated and the demand for nutrient solution to meet seedling cultivation tasks of different scales.

[0030] In addition, the design of the moving wheel 14 also makes the device more stable and safe when adjusting the volume. Traditional devices may need to lift or move heavy parts when adjusting the volume, which not only increases the difficulty of operation, but also may bring potential safety hazards. However, the sliding design of the moving wheel 14 of the present device makes the volume adjustment easy and stable, avoiding potential safety risks.

[0031] 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 shell 1, a moving block 17 is fixedly installed at the bottom of the external reinforcement shell 4, an adjusting screw 18 is installed on the shaft seat 15, one end of the adjusting screw 18 is fixedly connected to the output shaft of the motor 16, and the adjusting screw 18 threadably passes through the moving block 17, and is used to drive the movement of the external reinforcement shell 4 and the auxiliary shell 2 and the extension and retraction of the telescopic shell 3, thereby controlling the internal volume of the water tank.

[0032] In this embodiment, the bottom of the main housing 1 is fixedly installed with a shaft seat 15 and a motor 16, and an adjusting screw 18 is rotatably installed on the shaft seat 15, and one end of the adjusting screw 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 external reinforcement shell 4, and the adjusting screw 18 is threadedly penetrated through the moving block 17. When the motor 16 is started, its output shaft will drive the adjusting screw 18 to rotate, and then drive the moving block 17 to move along the axial direction of the adjusting screw 18 through the thread transmission. This movement will drive the external reinforcement shell 4 and the auxiliary shell 2 to move together, thereby controlling the telescopic state of the telescopic shell 3 and accurately adjusting the internal volume of the water storage tank.

[0033] In a further preferred embodiment of the present invention, a placement hole 19 is opened on the seedling water pipe 11 for placing the seedling planting basket 12, and the upper part of the seedling planting basket 12 has an edge, and the diameter of the edge is larger than the aperture of the placement hole 19.

[0034] In this embodiment, placement holes 19 are provided on the seedling water pipe 11, and the size and shape of these placement holes 19 ensure that the seedling planting basket 12 can be stably placed. At the same time, the upper part of the seedling planting basket 12 is designed with an edge, and the diameter of the edge is larger than the aperture of the placement hole 19, so as to provide additional support and stability when placed, and prevent the seedling planting basket 12 from slipping or tilting during the flow of nutrient solution or operation.

[0035] In actual operation, the user only needs to align the edge of the seedling planting basket 12 with the placement hole 19 and then gently put it in. Since the diameter of the edge is larger than the aperture of the placement hole 19, the seedling planting basket 12 will be firmly stuck in the placement hole 19 without additional fixing measures.

[0036] In a further preferred embodiment of the present invention, both ends of the seedling water pipe 11 are detachably provided with a water inlet joint 20 and a drainage joint 21, and the water inlet joint 20 and the drainage joint 21 are both watertightly connected to the seedling water pipe 11; a plurality of butt joints 22 with valves are fixedly mounted on the support plate 6; the number of the butt joints 22 is equal to the number of the seedling water pipe 11, the water inlet joint 20 and the drainage joint 21; the butt joints 22 are butt-jointed with the water inlet joint 20 at the corresponding position; a gear screw barrel 23 is provided on the external threaded sleeve of the butt joint position between the butt joint 22 and the water inlet joint 20; a water pump 24 is provided in the sub-shell 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 to a plurality of butt joints 22, and is used to pump the aqueous solution into the seedling water pipe 11 for absorption by the plants in the seedling planting basket 12.

[0037] In this embodiment, the two ends of the seedling water pipe 11 are detachably provided with a water inlet joint 20 and a drainage joint 21, and a watertight connection is achieved between the two joints and the seedling water pipe 11, ensuring the stability and safety of the nutrient solution during the transportation process. At the same time, a plurality of butt joints 22 with valves are fixedly installed on the support plate 6, and the number of these butt joints 22 is equal to the number of the seedling water pipe 11, the water inlet joint 20 and the drainage joint 21, so as to achieve one-to-one precise docking.

[0038] In actual operation, the user only needs to dock the water inlet connector 20 with the docking pipe 22 at the corresponding position, and set the gear screw barrel 23 on the external thread 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 auxiliary shell 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 to a plurality of docking pipes 22. When the water pump 24 is started, it will extract nutrient solution from the water tank, and pump the nutrient solution into the seedling water pipe 11 through the liquid supply pipe 25 and the docking pipe 22 for absorption by the plants in the seedling planting basket 12.

[0039] 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, and a plurality of drainage pipes 27 are fixedly installed on the drainage joints 21. The discharge end of the drainage pipe 27 is inserted into the corresponding water receiving pipe 26 to return the aqueous solution in the seedling water pipe 11 into the main shell 1 through the return water support shell 5.

[0040] In this embodiment, a plurality of water receiving pipes 26 are fixedly installed on the water return support shell 5, and the positions and numbers of these water receiving pipes 26 match the drainage joints 21. At the same time, a drainage pipe 27 is fixedly installed on each drainage joint 21, and the discharge end of the drainage pipe 27 is cleverly inserted into the corresponding water receiving pipe 26. This design enables the aqueous solution in the seedling water pipe 11 to flow smoothly into the water receiving pipe 26 through the drainage pipe 27 when discharged, and finally flow back into the main housing 1, thereby realizing the recycling and conservation of the aqueous solution.

[0041] In actual operation, when the aqueous solution in the seedling water pipe 11 needs to be discharged, the aqueous solution will flow into the water receiving pipe 26 along the drain pipe 27. Since the water receiving pipe 26 is connected with the return water support shell 5 and the inside of the main shell 1, the aqueous solution will eventually flow back into the water storage tank in the main shell 1 for subsequent seedling cultivation. This design not only simplifies the operation process, but also improves the utilization rate and saving effect of the aqueous solution.

[0042] In a further preferred embodiment of the present invention, a plurality of pipe placing positioning plates 28 are fixedly installed on the return water support shell 5, and the plurality of pipe placing positioning plates 28 are staggeredly located above the plurality of water receiving pipes 26, and a positioning notch 29 is provided on the plurality of pipe placing positioning plates 28 for inserting and positioning the drainage pipe 27, and the width of the positioning notch 29 is equal to the diameter of the drainage pipe 27.

[0043] In this embodiment, a plurality of pipe placement positioning plates 28 are fixedly installed on the return water support shell 5. These 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. The width of these positioning notches 29 is equal to the diameter of the drain pipe 27, so that the drain pipe 27 can be accurately inserted and fixed in the positioning notch 29.

[0044] In actual operation, when placing the seedling water pipe 11, the user only needs to align the drainage 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 firmly fixed in the positioning notch 29, avoiding the problem of poor reflux 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 reflux system.

[0045] In a further preferred embodiment of the present invention, a filter screen 30 is fixedly installed in the main shell 1 for filtering the reflowing aqueous solution, and the side of the main shell 1 has a cleaning port. The side of the main shell 1 is detachably mounted with a closing plate 31 for sealing the cleaning port using bolts.

[0046] In this embodiment, the filter 30 is fixedly installed in the main housing 1, located at a key position of the reflux path, for filtering the refluxed aqueous solution and removing impurities and particulate matter therein. In addition, a cleaning port is provided on the side of the main housing 1, and the design of this cleaning port is convenient for the user to clean and maintain the filter 30. In order to ensure the sealing and detachability of the cleaning port, we use a bolt connection method and install a closing plate 31 to block the cleaning port.

[0047] In actual operation, when the filter 30 needs to be cleaned or replaced, the user only needs to unscrew the bolts on the closing plate 31 and remove the closing plate 31 to easily access the filter 30. Then, the user can clean or replace the filter 30 to ensure its filtering effect. After cleaning, the closing plate 31 is reinstalled on the main housing 1 with bolts to complete the entire maintenance process.

[0048] In a further preferred embodiment of the present invention, a replenishing pipe 32 with a valve is installed on the top of the main shell 1, and a sewage pipe 33 with a valve is installed on the bottom of the side of the main shell 1.

[0049] In this embodiment, a supplementary pipe 32 with a valve is installed on the top of the main housing 1. This design allows the user to easily add new aqueous solution or nutrient solution to the main housing 1 through the supplementary pipe 32 to meet the needs of the seedling raising process. At the same time, a sewage pipe 33 with a valve is installed at the bottom of the side of the main housing 1. This design allows the user to regularly discharge sewage or waste liquid in the main housing 1 to keep the main housing 1 clean and hygienic.

[0050] 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 sewage or waste liquid in the main housing 1, the user only needs to open the valve on the sewage pipe 33 and discharge the sewage or waste liquid through the sewage pipe 33. These two designs not only simplify the operation process, but also improve work efficiency.

[0051] In a further preferred embodiment of the present invention, the seedling planting basket 12 is a truncated cone structure as a whole, and its diameter gradually decreases from top to bottom. The seedling planting basket 12 is divided into two halves of the basket body, and the two halves of the basket body are detachably connected. The top of the seedling planting basket 12 is a seedling release opening 34, and the bottom is a root opening 35. A plurality of water-permeable openings 36 are opened around the periphery of the seedling planting basket 12, and a positioning identification point 37 is provided on the inner side of one half of the basket body for automatic equipment identification. A grabbing suction cup and an information reading and storage module 38 are also provided on this half of the basket body, which is a sheet structure with an identification pattern set on the surface for information reading or storage to facilitate digital management.

[0052] 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.

[0053] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: 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.

[0054] 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.

[0055] 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. 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. 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.

[0056] In another embodiment of the present invention, the combined seedling planting device also includes a plurality of synchronous locking mechanisms, and the synchronous locking mechanisms include assembly holes 41 opened on both sides of the main pipe seat 10, and driving screw barrels 42 are rotatably installed in the two assembly holes 41, and interference screws 43 are threadedly installed in the two driving screw barrels 42. When the two driving screw barrels 42 drive the two interference screws 43 to approach each other, they respectively interfere with the two sides of the seedling water pipe 11 for fixing the seedling water pipe 11, and the two interference screws 43 are opened with rectangular through holes 44, and support frames 45 are fixedly installed on both sides of the main pipe seat 10, and the two Rectangular guide rods 46 are fixedly installed on the support frame 45, and the two rectangular guide rods 46 are respectively inserted into the two rectangular through holes 44, and are used to drive the screw barrel 42 to rotate and drive the conflicting screw 43 to guide when it moves. An assembly plate 47 is fixedly installed on the second supporting plate 8, and a synchronous shaft 48 is rotatably installed on the assembly plate 47. Sprocket wheels 49 are fixedly mounted on both ends of the synchronous shaft 48 and the two driving screw barrels 42, and the same chain 50 is mounted on the corresponding two sprocket wheels 49, so that the synchronous shaft 48 can drive the two driving screw barrels 42 to rotate at the same time, thereby driving the two conflicting screw barrels 43 to move closer to or away from each other.

[0057] In this embodiment, a plurality of synchronous locking mechanisms are introduced to stably fix the seedling water pipe 11. Specifically, the synchronous locking mechanism includes an assembly hole 41 provided on both sides of the main pipe seat 10, and a driving screw 42 is rotatably installed in the assembly hole 41. The driving screw 42 is internally threaded with a conflicting screw 43, and when the two driving screws 42 rotate synchronously, they will drive the two conflicting screws 43 to move closer to or away from each other. In order to ensure the stability of the movement of the conflicting screw 43, a rectangular perforation 44 is provided on the conflicting screw 43, and a support frame 45 is fixedly installed on both sides of the main pipe seat 10, and a rectangular guide rod 46 is fixedly installed on the support frame 45, and the rectangular guide rod 46 is inserted into the rectangular perforation 44 to play a guiding role. In addition, an assembly plate 47 is fixedly installed on the second supporting plate 8, and a synchronous shaft 48 is rotatably installed on the assembly plate 47. A sprocket 49 is fixedly installed on the synchronous shaft 48 and the two driving screws 42, and is connected by a chain 50 to realize the function of the synchronous shaft 48 driving the two driving screws 42 to rotate at the same time.

[0058] In actual operation, when the seedling water pipe 11 needs to be fixed, it is only necessary to rotate the synchronization shaft 48, which drives the two driving screw barrels 42 to rotate synchronously through the chain 50, thereby driving the two abutting screws 43 to approach each other and abut on both sides of the seedling water pipe 11, thereby firmly fixing the seedling water pipe 11. When the seedling water pipe 11 needs to be released, the user rotates the synchronization shaft 48 in the opposite direction, so that the two abutting screws 43 move away from each other, thereby releasing the seedling water pipe 11.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The introduction of the sprocket wheel 56, the chain 57, the chain shaft 58 and the hand wheel 59 enables multiple synchronous locking mechanisms to operate synchronously, thereby realizing the synchronous fixation and connection of multiple seedling water pipes 11. This design not only simplifies the operation process, reduces the difficulty of operation, but also greatly improves the work efficiency. The user only needs to turn the hand wheel 59 to complete the synchronous processing of multiple seedling water pipes 11, which greatly saves time and energy.

[0069] In another embodiment of the present invention, a plurality of air ports 60 are provided on the external reinforcement shell 4, and the plurality of air ports 60 correspond to the positions of the telescopic shell 3, and are used to balance the air pressure outside the telescopic shell 3 when the main shell 1 and the auxiliary shell 2 change the spacing.

[0070] In this embodiment, the air ports 60 are provided on the external reinforcement shell 4, and the position corresponds to the telescopic shell 3. When the spacing between the main shell 1 and the auxiliary shell 2 changes, such as the telescopic shell 3 is extended or retracted due to the placement or removal of the seedling water pipe 11, these air ports 60 can allow air to freely enter and exit, thereby balancing the air pressure between the main shell 1 and the auxiliary shell 2 and the outside of the telescopic shell 3. This design is intended to ensure that the telescopic shell 3 will not be subjected to unnecessary resistance or damage due to the difference in air pressure during the extension and retraction process.

[0071] To sum up, compared with the related art, the present device controls the total volume of the water 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 shell 1 and the auxiliary shell 2, and can flexibly adapt to seedling water pipes 11 of different lengths to ensure that the device can adapt to diverse seedling needs.
