[0002] Sweet potato is a high-yielding and adaptable food crop, which is closely related to industrial and agricultural production and people's livelihood. In addition to being used as a staple food, the tuber is also an important raw material for food processing, starch and alcohol manufacturing industries. The roots, stems and leaves are also excellent feeds. The cultivation of sweet potato seedlings refers to a series of technical operation processes starting from the selection and treatment of sweet potato seeds to the cultivation of suitable sweet potato seedlings for transplanting. First, disease-free, injury-free sweet potato seeds with excellent variety characteristics are selected. After disinfection and other treatments, they are placed on the carefully prepared seedbed, ensuring sufficient light and timely and appropriate topdressing, etc. Through scientific management, the sweet potato seedlings grow vigorously. When the seedlings grow to a certain height and the number of leaves, and have strong adaptability, they can be transplanted into the field for further growth and development, thus laying a foundation for the high-yield and bumper harvest of sweet potatoes.

[0003] Chinese Patent with publication number CN222707245U discloses a sweet potato cultivation device, the structure of which includes: a base, a cultivation box and a pair of electric push rods are connected above the base, the top of the electric push rod is connected with a housing, a limiting mechanism is arranged inside the housing, and a U-shaped plate is connected above the housing through the limiting mechanism; a feeding mechanism is arranged at the middle position above the base. After evenly cutting the sweet potatoes and placing them in the positioning holes of the U-shaped plate, and placing the U-shaped plate into the cultivation box, the water pump is turned on, and the culture solution in the culture solution tank is introduced into the water distribution pipe through the first water pipe and the second water pipe, and sprayed out through the nozzle, submerging the sweet potatoes in the culture solution, and controlling the lifting of the U-shaped plate through the electric push rod to keep part of the tubers exposed above the liquid surface, so as to ensure sufficient nutrients required for sweet potato cultivation. This device can effectively avoid the influence of natural disasters on sweet potato cultivation and improve the survival rate.

[0004] However, the above-mentioned prior art has the following deficiencies: during the growth process of sweet potato seedlings, the roots of different seedlings are easily entangled with each other, resulting in difficult separation of the roots during later seedling lifting and transplanting, which not only increases the difficulty and labor cost of seedling lifting, but also easily damages the roots, prolongs the slow seedling stage after transplanting, and reduces the survival rate of the seedlings. Summary of the Invention

[0005] The purpose of the present invention is to provide a sweet potato seedling cultivation device to solve the problem that during the growth process of sweet potato seedlings, the roots of different seedlings are easily entangled with each other, resulting in difficult separation of the roots during later seedling lifting and transplanting, which not only increases the difficulty and labor cost of seedling lifting, but also easily damages the roots, prolongs the slow seedling stage after transplanting, and reduces the survival rate of the seedlings.

[0006] To achieve the above object, the present invention provides the following technical solutions: a sweet potato seedling cultivation device, including: a base, on which a planting member for separating and growing sweet potato seedlings is rotatably provided, a motor is fixedly connected to the side end of the base, a watering member for introducing water flow into the planting member to irrigate the seedlings is provided on the planting member, and a locking member for switching the state of the planting member according to the storage amount of the liquid in the watering member is provided on the watering member;

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, the seedlings are separated by the planting parts and developed in the conical seedling pots composed of the first seedling pot, the second seedling pot and the third seedling pot, avoiding the entanglement of the roots of different seedlings, providing sufficient growth space for the roots of each seedling. The conical constraint of the closing holes and the elastic deformation of the springs cooperate to realize the automatic closing or unfolding of the seedling pots. When closed, the maximum diameter matches the closing holes to ensure good sealing. When unfolded, the hinge-type second seedling pot and third seedling pot naturally droop, which can avoid damaging the roots that have developed and matured.

[0019] 2. In the present invention, the liquid is injected through the top water inlet of the flow dividing cylinder in the watering part, and the liquid is accurately and evenly distributed to the symmetric first water storage tank and second water storage tank by the triangular prism flow dividing plate, ensuring that the water volume in the two tanks is always equal and guaranteeing the normal operation of subsequent functions. The floating plate and the closing block can automatically control the liquid outflow according to the liquid volume in the water storage tank and the inclination state of the device, without frequent manual operation, saving a large amount of labor costs. Moreover, this slow and stable liquid outflow method can ensure that the seedlings continuously and moderately absorb water, effectively avoiding damage to the seedling roots due to excessive water flow, and significantly improving the efficiency and quality of seedling cultivation.

[0020] 3. In the present invention, through the locking part in the early stage of seedling cultivation, it can effectively prevent the random movement of the water flowing part due to the change of the liquid weight in the water storage tank, ensuring that the seedling pots are stably in the closed state and creating a good initial growth environment for the seedlings. In the stage of liquid reduction, its precise unlocking mechanism can closely cooperate with the liquid volume in the water storage tank and the position of the floating plate to appropriately release the restriction on the water flowing part, enabling the water flowing part to move upward under the action of the spring and smoothly realizing the separation of the seedling pots, facilitating the subsequent operation of taking out the seedlings, greatly improving the automation degree and working reliability of the entire cultivation device, and reducing the complexity and error probability of manual intervention.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0035] Refer to Figures 1 to 3 In the embodiments of the present invention, a sweet potato seedling cultivation device includes: a base 1, a planting member 3 for separating and growing sweet potato seedlings is rotatably arranged on the base 1, a motor 2 is fixedly connected to the side end of the base 1, a watering member 4 for introducing water flow into the planting member 3 to irrigate the seedlings is arranged on the planting member 3, the opening and closing state of the seedling pots in the planting member 3 can be switched by the change of the water volume in the watering member 4, and a locking member 5 for restricting the state of the planting member 3 is arranged on the watering member 4.

[0036] Refer to Figures 4 to 6, the planting member 3 includes a first gear 31 rotatably connected to the base 1. One end of the first gear 31 is fixedly connected to an upper fixing plate 32. There are two sets of the first gears 31, symmetrically distributed on both sides of the upper fixing plate 32. A stretching member 314 is fixedly connected to the side end of the upper fixing plate 32. One end of the stretching member 314 is fixedly connected to a water flowing member 33. There are four sets of the stretching members 314, symmetrically distributed on both sides of the upper fixing plate 32. A closing hole 37 is formed through the top end of the upper fixing plate 32. The inner wall of the closing hole 37 is conical, wider at the top and narrower at the bottom. There are multiple sets of the closing holes 37, evenly distributed on the top end of the upper fixing plate 32. A connecting block 39 is fixedly connected to the top end of the water flowing member 33. A first seedling pot 310 is fixedly connected to the top end of the connecting block 39. There are multiple sets of the connecting blocks 39 and multiple sets of the first seedling pots 310. The bottom end of each set of the first seedling pots 310 is fixedly connected to two connecting blocks 39, and each set of the first seedling pots 310 corresponds to one closing hole 37. A water absorption rope 311 is arranged at the bottom end inside each set of the first seedling pots 310. The water absorption rope 311 is in a mountain shape, and the three tips of the mountain-shaped water absorption rope 311 respectively penetrate through the first seedling pot 310 and the top end of the water flowing member 33. On both sides of each set of the first seedling pots 310, a second seedling pot 312 and a third seedling pot 313 are symmetrically distributed. The second seedling pot 312 and the third seedling pot 313 have the same size, and the bottom ends of the second seedling pot 312 and the third seedling pot 313 are respectively hinged to the bottom end of the first seedling pot 310 through two hinges. The first seedling pot 310, the second seedling pot 312, and the third seedling pot 313 penetrate through the closing hole 37. When the first seedling pot 310, the second seedling pot 312, and the third seedling pot 313 are fitted together, a complete conical seedling pot is formed. The conical seedling pot is wider at the top and narrower at the bottom, and the maximum diameter of the conical seedling pot is the same as the maximum inner diameter of the closing hole 37. The stretching member 314 includes a first fixing ear 34 fixedly connected to the side end of the upper fixing plate 32. A spring 36 is fixedly connected to the bottom end of the first fixing ear 34. A second fixing ear 35 is fixedly connected to the bottom end of the spring 36. The second fixing ear 35 is fixedly connected to the side end of the water flowing member 33. The water flowing member 33 includes a lower fixing plate 317 fixedly connected to the side end of the second fixing ear 35. A water flowing groove 38 is formed through the side end of the lower fixing plate 317. A water absorption groove 315 is formed through the top end of the lower fixing plate 317. The water absorption groove 315 is communicated with the water flowing groove 38. A top plate 316 is fixedly connected to the top end inside the water absorption groove 315. There are multiple sets of the top plates 316, and each set of the top plates 316 is fixedly connected to a connecting block 39 at the bottom end of a set of the first seedling pots 310. One end of the water absorption rope 311 penetrates through the water absorption groove 315 and enters the water flowing groove 38. When the irrigation liquid is poured into the flow dividing cylinder 431, the liquid is divided and enters the first water storage tank 41 and the second water storage tank 42. The weight of the water storage tanks increases, the second fixing ear 35 moves downward, the spring 36 stretches, driving the water flowing member 33 to move downward. The first seedling pot 310, the second seedling pot 312, and the third seedling pot 313 are gradually closed under the restriction of the closing hole 37. When the spring 36 returns to its original length without restriction, it drives the water flowing member 33 to move upward, ejecting the seedling pot from the closing hole 37.The seedling pots II 312 and III 313 are hinged and rotated under the action of gravity to achieve separation.

[0037] Adopting the above solution: By separating the seedlings in the conical seedling pots composed of the seedling pot I 310, the seedling pots II 312 and III 313, the problem of root entanglement of different seedlings is avoided, ensuring that each seedling has enough space for root growth. Through the combined action of the conical constraint of the closing hole 37 and the elastic deformation of the spring 36, the automatic closing or unfolding of the seedling pot is realized. When closed, the maximum diameter matches the closing hole 37 to ensure tightness. When unfolded, the hinged seedling pots II 312 and III 313 droop naturally, avoiding damage to the mature roots.

[0038] Refer to Figures 7 to 10, the watering member 4 includes a water storage tank one 41 and a water storage tank two 42 that are connected through a water flow groove 38. The water storage tank one 41 and the water storage tank two 42 are symmetrically distributed on both sides of the lower fixing plate 317 and are fixedly connected to the lower fixing plate 317. A fixing frame 411 is fixedly connected to the side end of the upper fixing plate 32. There are two groups of fixing frames 411, which are symmetrically distributed on both sides of the upper fixing plate 32. The water storage tank one 41 and the water storage tank two 42 are respectively slidably inserted into a group of fixing frames 411. The cross-sections of the water storage tank one 41 and the water storage tank two 42 are T-shaped, and the fixing frame 411 is U-shaped. One end of the water inlet member 43 is connected to the side end of the water storage tank one 41, and one end of the water inlet member 43 is connected to the side end of the water storage tank two 42. A limiting plate 44 is fixedly connected to the inner top of the water flow groove 38. A connecting rod 45 is slidably inserted into the limiting plate 44. A limiting block 46 is fixedly connected to the outer side of the connecting rod 45. There are two groups of limiting plates 44, which are symmetrically distributed on both sides of the limiting block 46. A closing block 47 is fixedly connected to the end face of the connecting rod 45. There are two groups of closing blocks 47, which are symmetrically distributed at both ends of the connecting rod 45. The two groups of closing blocks 47 are respectively slidably inserted into the water outlet ports of the water storage tank one 41 and the water storage tank two 42. One side of the top of the closing block 47 is an arc surface. A water inlet groove 48 is opened at the inner bottom end of the water outlet ports of the water storage tank one 41 and the water storage tank two 42. The cross-section of the water inlet groove 48 is triangular, and the width of the top of the water inlet groove 48 is greater than the width of the bottom of the closing block 47. A rotating rod 49 is rotatably connected to the inner side of the base 1. A second gear 410 is fixedly connected to the outer side of the rotating rod 49. There are two groups of second gears 410, and each group of second gears 410 is meshed with a first gear 31. The output end of the motor 2 penetrates through the base 1 and is fixedly connected to the rotating rod 49. The water inlet member 43 includes a first water inlet pipe 432 that is connected to the water storage tank one 41, and a second water inlet pipe 433 that is connected to the water storage tank two 42. The first water inlet pipe 432 is connected to a flow dividing cylinder 431, and the second water inlet pipe 433 is connected to the flow dividing cylinder 431. The first water inlet pipe 432 and the second water inlet pipe 433 are symmetrically distributed on both sides of the flow dividing cylinder 431. The first water inlet pipe 432, the second water inlet pipe 433, and the flow dividing cylinder 431 are Y-shaped. The water inlet position of the flow dividing cylinder 431 is higher than the connection positions of the first water inlet pipe 432 and the second water inlet pipe 433 with the water storage tank one 41 and the water storage tank two 42. A flow dividing plate 434 is fixedly connected to the inner bottom end of the flow dividing cylinder 431. The flow dividing plate 434 is a triangular prism, and the flow dividing plate 434 is located at the connection port of the first water inlet pipe 432, the second water inlet pipe 433, and the flow dividing cylinder 431 to divide the liquid entering the flow dividing cylinder 431, so that it is evenly divided and flows into the first water inlet pipe 432 and the second water inlet pipe 433 respectively. The watering member 4 injects liquid through the water inlet at the top of the Y-shaped flow dividing cylinder 431, and is evenly divided into the first water inlet pipe 432 and the second water inlet pipe 433 by the triangular prism flow dividing plate 434, so that the symmetric water storage tank one 41 and the water storage tank two 42 store water synchronously. The liquid impacts the floating plate 55 and seeps into the bottom of the tank through its drain holes. As the water level rises, the floating plate 55 moves upward under the buoyancy force to expose the water outlet. At this time, the increased weight of the symmetric water storage tanks drives the second fixing ear 35 to press down the spring 36,The trigger water flow member 33 moves downward as a whole, and the closing block 47 in the water outlet of the double water tank remains stationary due to the water pressure balance on both sides. When the device is driven to rotate by the motor 2, the closing block 47 of the low-level water tank is pushed by the water pressure, and the triangular water inlet groove 48 is connected with the water flow groove 38 through the sliding of the connecting rod 45 to form the main irrigation channel. The closing block 47 of the high-level water tank partially withdraws to produce a slow flow gap. The limit plate 44 and the limit block 46 cooperate to maintain the flow rate stability. The water in the water flow groove 38 continuously supplies water to the seedling pot through the capillary action of the mountain-shaped water absorption rope 311. When the water level drops to the critical value, the floating plate 55 moves downward to trigger the engagement of the guide block 2 510 with the guide block 3 511, release the restriction of the locking member 5, and the closing block 47 is reset to complete the irrigation cycle.

[0039] The above scheme is adopted: through the diverter tube 431 and the diverter plate 434, the irrigation liquid can be accurately and evenly distributed to the two water tanks, ensuring that the water volume in the two tanks is always equal, and ensuring the correct implementation of subsequent functions. Utilizing the design of the float plate 55 and the closing block 47, the liquid outflow can be automatically controlled according to the liquid volume in the water tank and the tilt state of the device. There is no need for frequent manual operation, which greatly saves labor costs. Moreover, this slow and stable liquid outflow method can ensure that the seedlings absorb water continuously and appropriately, avoid the soil being dispersed or the root system of the seedlings being damaged due to excessive water flow, and effectively improve the efficiency and quality of seedling cultivation.

[0040] Reference Figures 11 to 12The locking member 5 includes a rotating shaft 51 that penetrates the second fixed ear 35 and is rotatably connected to the second fixed ear 35. The rotating shaft 51 is I-shaped. A rotating rod 52 is fixedly connected to the top of the rotating shaft 51. A through hole 53 is penetrated through the top of the fixed ear 34, and the top of the rotating rod 52 penetrates the through hole 53 and is fixedly connected to a gear 3 54. The through hole 53 is in the shape of a Chinese character. A limiting block 512 is fixedly connected to the side end of the rotating rod 52. Two groups of limiting blocks 512 are provided, which are symmetrically distributed on the side ends of the rotating rod 52. The cross-sectional areas of the limiting blocks 512 and the rotating rod 52 are the same as the size of the through hole 53. A floating plate 55 is slidably connected in the water storage tank 242. A plurality of drainage holes are penetrated on the floating plate 55, so that the liquid flows to the bottom of the floating plate 55. A through hole 2 56 is provided at the top of the plate 55, a rotating rod 2 57 is rotatably connected to the bottom end of the water tank 2 42, a gear 4 58 is fixedly connected to the top of the rotating rod 2 57, and the gear 4 58 is meshed with the gear 3 54, a guide block 1 59 is fixedly connected to the outside of the rotating rod 1 52, a guide block 2 510 is fixedly connected to the outside of the rotating rod 1 52, the guide block 1 59 and the guide block 2 510 are of the same size, the guide block 1 59 and the guide block 2 510 are spiral, and the guide block 1 59 and the guide block 2 510 are provided in two groups, which are symmetrically distributed on the outside of the rotating rod 1 52, the inner wall of the through hole 2 56 is fixedly connected to the guide block 3 511, the guide block 3 511 is provided in two groups, which are symmetrically distributed on the inner wall of the through hole 2 56, and the through hole 2 56 is spiral. The guide block 3 511 is respectively matched with the guide block 1 59 and the guide block 2 510. Under the guidance of the cooperation between the guide block 3 511 and the guide block 1 59 or the guide block 2 510, the rotating rod 2 57 rotates 90 degrees. The locking member 5 is provided with four groups, which are symmetrically distributed on both sides of the upper fixed plate 32. The water storage tank 1 41 is also provided with a floating plate 55, a through hole 2 56, a rotating rod 2 57, a gear 4 58, a guide block 1 59, a guide block 2 510 and a guide block 3 511. The through hole 2 56, the rotating rod 2 57 and the gear 4 58 in the water storage tank 1 41 and the water storage tank 2 42 are each provided with two groups, which are symmetrically distributed on the top of the floating plate 55. When the irrigation liquid is poured into the diversion cylinder 431, as the liquid in the water storage tank 1 41 and the water storage tank 2 42 increases, the weight increases. The fixing ear 35 moves downward and the spring 36 stretches. At this time, the rotating shaft 51 that penetrates the fixing ear 35 and is connected to the rotating rod 1 52 moves accordingly, and the limiting block 512 moves to the bottom of the fixing ear 34 through the through hole 1 53. When the floating plate 55 moves upward due to the increase of liquid in the water storage tank, the guide block 3 511 on the inner wall of the through hole 2 56 at the top of the floating plate 55 abuts against the guide block 1 59 on the outer side of the rotating rod 1 52. Due to the spiral structure of the two, the rotating rod 2 57 rotates 90 degrees under the guidance of the cooperation, and the engagement of the gear 4 58 with the gear 3 54 drives the rotating rod 1 52 to rotate 90 degrees, so that the limiting block 512 is misaligned with the through hole 1 53, thereby realizing the restriction of the water flow member 33, preventing it from returning to the initial state prematurely due to the subsequent reduction of gravity.When the liquid in the water storage tank decreases and the floating plate 55 moves downward to abut against the arc surface of the closing block 47, pushing the closing block 47 out to restore the initial state of blocking the water outlet, the guide block two 510 on the outer side of the rotating rod one 52 is inserted into the through hole two 56 to abut against the guide block three 511, rotating the rotating rod two 57 by ninety degrees again. Through gear transmission, the rotating rod one 52 rotates by ninety degrees, and the limiting block 512 is aligned with the through hole one 53 again, releasing the restriction on the water flowing part 33, allowing the spring 36 to drive the water flowing part 33 to move upward.

[0041] Adopting the above solution: Through the locking part 5 in the early stage of seedling cultivation, it can effectively prevent the water flowing part 33 from moving randomly due to the change of the liquid weight in the water storage tank, ensuring that the seedling pot is stably in the closed state, providing a good initial growth environment for the seedlings, and avoiding the seedlings from being interfered by the premature opening and closing of the pot body. In the stage of liquid reduction, its precise unlocking mechanism can cooperate with the liquid volume in the water storage tank and the position of the floating plate 55 to just right release the restriction on the water flowing part 33, enabling the water flowing part 33 to move upward under the action of the spring 36, realizing the separation of the seedling pot, facilitating the subsequent operation of taking out the seedlings, greatly improving the automation degree and working reliability of the entire cultivation device, and reducing the complexity and error probability of manual intervention.

[0042] The working principle of the present invention is as follows: First, the irrigation liquid is poured into the shunt cylinder 431. The triangular prism-shaped shunt plate 434 in the cylinder is located at the connection ports of the first water inlet pipe 432, the second water inlet pipe 433 and the shunt cylinder 431, and can evenly shunt the liquid into the first water inlet pipe 432 and the second water inlet pipe 433. Subsequently, the liquid flows into the first water storage tank 41 and the second water storage tank 42 through the first water inlet pipe 432 and the second water inlet pipe 433 respectively. The liquid flowing into the water storage tank first falls on the floating plate 55 with multiple groups of drainage holes and flows through the drainage holes to the lower part of the floating plate 55. As the liquid continuously increases, the floating plate 55 gradually moves upward due to buoyancy, and the water outlets of the first water storage tank 41 and the second water storage tank 42 are exposed accordingly. Due to the function of the shunt plate 434, the liquid amounts in the two water storage tanks are always the same. The liquid thrusts on the side ends of the two groups of closing blocks 47 located in the water outlets of the first water storage tank 41 and the second water storage tank 42 are the same, so the closing blocks 47 remain balanced and are stably located in the water outlets. At the same time, as the weight of the first water storage tank 41 and the second water storage tank 42 increases due to the increase in liquid, the second fixing ear 35 moves downward, and the spring 36 stretches. During this process, the limiting block 512 moves through the first through hole 53 to the lower part of the first fixing ear 34 until the T-shaped first water storage tank 41 and the second water storage tank 42 are respectively abutted against a group of fixing frames 411. At this time, the second fixing ear 35 moves downward to the limit position, and the water flowing part 33 also moves downward to the limit position synchronously, thereby driving the first seedling pot 310, the second seedling pot 312 and the third seedling pot 313 to move downward. Under the restriction of the conical inner wall of the closing hole 37, the first seedling pot 310, the second seedling pot 312 and the third seedling pot 313 are gradually closed. Then, the floating plate 55 continues to move upward until the first guiding block 59 enters the second through hole 56 and abuts against the third guiding block 511. Due to the spiral abutting surfaces of the first guiding block 59 and the third guiding block 511, the second rotating rod 57 rotates by ninety degrees accordingly. Through the meshing action of the fourth gear 58 and the third gear 54, the first rotating rod 52 also rotates by ninety degrees, causing the limiting block 512 to be misaligned with the first through hole 53, realizing the restriction of the water flowing part 33 and preventing the spring 36 from driving the water flowing part 33 to return to the open and closed state in advance due to the subsequent decrease in gravity. Thus, the liquid addition is completed. After the liquid addition is completed, fill the closed seedling pots with soil and plant sweet potato seedlings. Then start the motor 2. The output end of the motor 2 drives the rotating rod 49 to rotate. Under the meshing action of the first gear 31 and the second gear 410, the upper fixing plate 32 starts to rotate, and the planting part 3 and the irrigation part 4 also rotate synchronously, ensuring that the seedlings in the seedling pots can always receive sunlight. During the rotation process, the symmetrically distributed first water storage tank 41 and the second water storage tank 42 will tilt. When the water outlet of the second water storage tank 42 or the first water storage tank 41 tilts downward, the other side of the water outlet of the first water storage tank 41 or the second water storage tank 42 tilts upward. The balance state of the two groups of closing blocks 47 is broken. The liquid thrust on the closing block 47 in the water storage tank 41 or the second water storage tank 42 with the water outlet tilting downward increases, while the thrust on the other closing block 47 decreases, causing the connecting rod 45, the limiting block 46 and the closing block 47 to slide downward.Until the limiting block 46 abuts against the limiting plate 44. At this time, the triangular water inlet grooves 48 at the bottom ends of the group of closing blocks 47 at the lower position are respectively communicated with the inside of the water storage tank and the water flow groove 38. A part of the group of closing blocks 47 at the higher position disengages from the water outlet of the water storage tank, creating a gap with the water outlet. The liquid slowly flows out of the water storage tank from this gap, flows through the water flow groove 38 and into another group of water storage tanks. Due to the action of the limiting block 46 and the limiting plate 44, no matter how the inclination angle changes, it can ensure that the liquid flows out slowly. The liquid flowing in the water flow groove 38 is sucked into the soil in the seedling pots by the mountain-shaped water-absorbing ropes 311 for the seedlings to absorb. As the liquid in the water storage tank 1 or the water storage tank 2 gradually decreases, under the restriction of the limiting block 512, even if the gravity of the water storage tank 1 or the water storage tank 2 is less than the elastic force of the spring 36, they cannot move upward and reset until the floating plate 55 moves downward to abut against the arc surface of the closing block 47, pushing out the closing block 47 in the water outlet of the water storage tank 1 or the water storage tank 2. The two groups of closing blocks 47 return to the initial state and respectively return to the water outlets of the water storage tank 1 and the water storage tank 2. At the same time, the guide block 2 510 is inserted into the through hole 2 56 and abuts against the guide block 3 511. Due to their spiral abutting surfaces, the rotating rod 2 57 rotates 90 degrees. With the meshing action of the gear 4 58 and the gear 3 54, the rotating rod 1 52 also rotates 90 degrees, and the limiting block 512 is realigned with the through hole 1 53. At this time, the spring 36 is no longer restricted and returns to its original length, driving the water flow part 33 to move upward, pushing out the seedling pots from the closing holes 37. The seedling pots 2 312 and the seedling pots 3 313 that lose the restriction of the closing holes 37 are hinged and rotated under the action of gravity to realize the separation of the seedling pots. Since the roots of the seedlings have developed and fixed the soil, after the seedling pots are separated, the seedlings in the seedling pots can be directly taken out; the seedlings are separated and grown in the conical seedling pots composed of the seedling pot 1 310, the seedling pot 2 312 and the seedling pot 3 13 by the planting part 3, avoiding the entanglement of the roots of different seedlings and providing sufficient growth space for the roots of each seedling. The conical constraint of the closing hole 37 and the elastic deformation of the spring 36 cooperate to realize the automatic closing or unfolding of the seedling pots. When closed, the maximum diameter matches the closing hole 37 to ensure good sealing. When unfolded, the hinge-type seedling pots 2 312 and the seedling pots 3 13 naturally droop, which can avoid damaging the mature roots. The liquid is injected through the top water inlet of the flow dividing cylinder 431 in the watering part 4, and the liquid is accurately and evenly distributed to the symmetric water storage tank 1 and the water storage tank 2 by the triangular prism flow dividing plate 434, ensuring that the water volume in the two tanks is always equal and guaranteeing the normal operation of the subsequent functions. The floating plate 55 and the closing block 47 can automatically control the liquid outflow according to the liquid volume in the water storage tank and the inclination state of the device, without frequent manual operation, saving a large amount of labor costs. Moreover, this slow and stable liquid outflow method can ensure that the seedlings continuously and moderately absorb water, effectively avoiding damage to the seedling roots due to excessive water flow and significantly improving the efficiency and quality of seedling cultivation. Through the locking part 5 in the early stage of seedling cultivation,It can effectively prevent the water flow part 33 from moving randomly due to the change of liquid weight in the water storage tank, ensure that the seedling pot is stably in a closed state, and create a good initial growth environment for the seedlings. In the liquid reduction stage, its precise unlocking mechanism can closely cooperate with the liquid volume in the water storage tank and the position of the floating plate 55, and just release the restriction on the water flow part 33, so that the water flow part 33 can move up under the action of the spring 36, smoothly realize the separation of the seedling pot, and facilitate the subsequent removal of the seedlings, which greatly improves the automation degree and working reliability of the entire cultivation device and reduces the complexity and error probability of manual intervention.
