Description

Technical Field

[0001] This invention relates to the field of seedling cultivation equipment technology, specifically a sweet potato seedling cultivation device. Background Technology

[0002] Sweet potato is a high-yield and highly adaptable food crop, closely related to industrial and agricultural production and people's lives. Besides being a staple food, its tubers are also important raw materials for food processing, starch and alcohol manufacturing. The roots, stems, and leaves are excellent fodder. Sweet potato seedling cultivation refers to a series of technical operations from seed potato selection and treatment to cultivating seedlings suitable for transplanting. First, disease-free, undamaged sweet potato seed potatoes with excellent varietal characteristics are selected. After disinfection and other treatments, they are placed on carefully prepared seedbeds, ensuring sufficient sunlight and timely and appropriate fertilization. Through scientific management, the sweet potato seedlings grow vigorously. Once the seedlings reach a certain height and number of leaves, and possess strong adaptability, they can be transplanted into the field for further growth and development, thus laying the foundation for a high-yield sweet potato harvest.

[0003] Chinese Patent Publication No. CN222707245U discloses a sweet potato cultivation device, the structure of which includes: a base, a cultivation box and a pair of electric push rods connected to the top of the base, a housing connected to the top of the electric push rods, a limiting mechanism inside the housing, and a U-shaped plate connected to the top of the housing through the limiting mechanism; a nutrient supply mechanism is set at the middle of the top of the base. By evenly cutting sweet potatoes into pieces and placing them in the positioning holes of the U-shaped plate, placing the U-shaped plate into the cultivation box, turning on the water pump, the nutrient solution in the nutrient 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, immersing the sweet potatoes in the nutrient solution. The electric push rods control the raising and lowering of the U-shaped plate to keep a portion of the tubers above the liquid surface, thereby ensuring sufficient nutrients for sweet potato cultivation. This device can effectively avoid the impact of natural disasters on sweet potato cultivation and improve the survival rate.

[0004] However, the above-mentioned existing technologies have the following shortcomings: During the growth of sweet potato seedlings, the roots of different seedlings are easily entangled together, making it difficult to separate the roots when transplanting seedlings later. This not only increases the difficulty of transplanting seedlings and labor costs, but also easily damages the roots, prolonging the seedling recovery period after transplanting and reducing the survival rate of seedlings. Summary of the Invention

[0005] The purpose of this invention is to provide a sweet potato seedling cultivation device to solve the problem that during the growth of sweet potato seedlings, the roots of different seedlings easily become entangled, making it difficult to separate the roots when transplanting. This not only increases the difficulty and labor cost of transplanting, but also easily damages the roots, prolongs the recovery period after transplanting, and reduces the survival rate of the seedlings.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sweet potato seedling cultivation device, comprising: a base, on which a planting component for separating and developing sweet potato seedlings is rotatably mounted, a motor is fixedly connected to the side end of the base, and an irrigation component is provided on the planting component for guiding water flow into the planting component to irrigate the seedlings, and a locking component is provided on the irrigation component for switching the state of the planting component according to the amount of liquid stored in the irrigation component;

[0007] The planting component includes a gear 1 rotatably connected to the base. One end of the gear 1 is fixedly connected to an upper fixing plate. An extension component is fixedly connected to the side end of the upper fixing plate. A water flow component is fixedly connected to one end of the extension component. A closed hole is opened through the top of the upper fixing plate. A connecting block is fixedly connected to the top of the water flow component. A seedling pot 1 is fixedly connected to the top of the connecting block. A water-absorbing rope is provided at the bottom of the inside of the seedling pot 1, and one end of the water-absorbing rope passes through the top of the seedling pot 1 and the top of the water flow component. A seedling pot 2 and a seedling pot 3 are symmetrically distributed on both sides of the seedling pot 1, and the seedling pot 2 and the seedling pot 3 are respectively hinged to the bottom of the seedling pot 1. The seedling pot 1, seedling pot 2, and seedling pot 3 pass through the closed hole.

[0008] When the liquid in the irrigation component is sucked into the soil in the seedling pot by the water-absorbing rope from the water flow component and absorbed by the seedling, the weight of the liquid in the irrigation component causes the water flow component to move downward, which causes the gravity of the extension component to gradually decrease. However, due to the locking state of the locking component, the extension component cannot return to its original length. When it decreases to a certain extent, the locking state of the locking component is released, the extension component returns to its original state, and the water flow component moves upward, pushing the seedling pot out of the closed hole. Seedling pot two and seedling pot three, which are no longer restricted by the closed hole, rotate hinged under the action of gravity, causing the seedling pots to separate.

[0013] As a further embodiment of the present invention: a rotating rod is rotatably connected to the inner side of the base, and a second gear is fixedly connected to the outer side of the rotating rod. The second gear meshes with the first gear, and the motor output end passes through the base and is fixedly connected to the rotating rod.

[0014] As a further embodiment of the present invention: the water inlet component includes a water inlet pipe 1 that is connected to a water storage tank 1, and a water inlet pipe 2 that is connected to a water storage tank 2.

The water inlet pipe 1 and the water inlet pipe 2 are symmetrically distributed on both sides of the diverter cylinder, and a diverter plate is fixedly connected to the bottom of the inside of the diverter cylinder.

[0015] As a further embodiment of the present invention: the locking member includes a rotating shaft that passes through and is rotatably connected to the second fixing lug. A rotating rod is fixedly connected to the top end of the rotating shaft. A through hole is opened through the top end of the first fixing lug, and a gear is fixedly connected to the top end of the first rotating rod through the through hole.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, seedlings are separated into conical seedling pots consisting of seedling pot one, seedling pot two, and seedling pot three by a planting component, which avoids the roots of different seedlings from getting entangled and provides sufficient growth space for the roots of each seedling. The conical constraint of the closed hole and the elastic deformation of the spring work together to realize the automatic closing or opening of the seedling pot. When closed, the maximum diameter matches the closed hole to ensure good sealing. When opened, the hinged seedling pot two and seedling pot three hang down naturally, which can avoid damage to the mature root system.

[0019] 2. In this invention, liquid is injected through the inlet at the top of the diversion cylinder in the pouring component. The liquid is then precisely and evenly distributed to the symmetrical water storage tank 1 and water storage tank 2 by the triangular prism diversion plate, ensuring that the water volume in the two tanks is always equal and guaranteeing the normal operation of subsequent functions. The float plate and the sealing block can automatically control the liquid outflow according to the liquid volume in the water storage tank and the tilt state of the device, eliminating the need for frequent manual operation and saving a lot of labor costs. Moreover, this slow and stable liquid outflow method can ensure that the seedlings continuously and appropriately 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 early stage of seedling cultivation, the locking component effectively prevents the water flow component from moving arbitrarily due to changes in the weight of the liquid in the water tank, ensuring that the seedling pot remains stably closed and creating a good initial growth environment for the seedlings. During the liquid reduction stage, its precise unlocking mechanism closely matches the liquid volume in the water tank and the position of the float plate, appropriately releasing the restriction on the water flow component. This allows the water flow component to move upward under the action of the spring, smoothly separating the seedling pot and facilitating the subsequent removal of the seedlings. This greatly improves the automation level and operational reliability of the entire cultivation device, and reduces the complexity and error probability of manual intervention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0035] Reference Figures 1 to 3 In this embodiment of the invention, a sweet potato seedling cultivation device includes: a base 1, a planting component 3 rotatably mounted on the base 1 for separating and developing sweet potato seedlings, a motor 2 fixedly connected to the side of the base 1, an irrigation component 4 for guiding water flow into the planting component 3 to irrigate the seedlings, the opening and closing state of the seedling pots in the planting component 3 can be switched by changing the amount of water in the irrigation component 4, and a locking component 5 for restricting the state of the planting component 3 is provided on the irrigation component 4.

[0036] Reference Figures 4 to 6The planting component 3 includes a gear 31 rotatably connected to the base 1. One end of the gear 31 is fixedly connected to an upper fixing plate 32. Two sets of gears 31 are symmetrically distributed on both sides of the upper fixing plate 32. An extension component 314 is fixedly connected to the side end of the upper fixing plate 32. One end of the extension component 314 is fixedly connected to a water flow component 33. Four sets of extension components 314 are symmetrically distributed on both sides of the upper fixing plate 32. A closed hole 37 is formed through the top of the upper fixing plate 32. The inner wall of the closed hole 37 is conical, wider at the top and narrower at the bottom. Multiple sets of closed holes 37 are evenly distributed at the top of the upper fixing plate 32. A connecting block 39 is fixedly connected to the top of the water flow component 33. A seedling pot 310 is fixedly connected to the top of the connecting block 39. Multiple sets of connecting blocks 39 are provided. Multiple sets of seedling pots 310 are provided. The bottom of each set of seedling pots 310 is fixedly connected to two sets of connecting blocks 39, and each set of seedling pots 310 corresponds to a set of closed holes 37. A set of water-absorbing ropes 311 is provided at the bottom of the inside of each set of seedling pots 310. The water-absorbing ropes 311 are in the shape of a mountain, and the three tips of the mountain-shaped water-absorbing ropes 311 pass through the top of the seedling pot 310 and the top of the water flow component 33, respectively. On both sides of each set of seedling pots 310, seedling pots 312 and 313 are symmetrically distributed. Seedling pots 312 and 313 are the same size, and the bottom of seedling pots 312 and 313 are hinged to the bottom of seedling pots 310 through two sets of hinges. Seedling pots 310, 312, and 313 pass through the closed holes 37. When the three seedling pots 310, 312, and 313 are fitted together at the closing hole 37, they form a complete conical seedling pot. The conical seedling pot is wider at the top and narrower at the bottom, and its maximum diameter is the same as the maximum inner diameter of the closing hole 37. The extension member 314 includes a 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 fixing ear 34, and a fixing ear 35 is fixedly connected to the bottom end of the spring 36. The fixing ear 35 is fixedly connected to the side end of the water flow member 33. The water flow member 33 includes a lower fixing plate 317 fixedly connected to the side end of the fixing ear 35. A water flow channel 38 is provided through the side end of the lower fixing plate 317, and a water suction channel 315 is provided through the top end of the lower fixing plate 317. The water suction channel 315 and the water flow channel are connected through the water flow channel. The water tank 315 is connected to a top plate 316 fixedly connected to its inner top. Multiple sets of top plates 316 are provided, each set being fixedly connected to a set of connecting blocks 39 at the bottom of a set of seedling pots 310. One end of the water-absorbing rope 311 passes through the water-absorbing tank 315 and enters the water-flowing tank 38. When irrigation liquid is poured into the diverting cylinder 431, the liquid flows into the first water storage tank 41 and the second water storage tank 42. The increased weight of the water storage tanks causes the second fixing lug 35 to move downwards, extending the spring 36 and causing the water-flowing component 33 to move downwards. The seedling pots 310, 312, and 313 gradually close under the constraint of the closing hole 37. When the spring 36 returns to its original length, it causes the water-flowing component 33 to move upwards, pushing the seedling pots out of the closing hole 37.Seedling pot 2 (312) and seedling pot 3 (313) separate by hinged rotation under the influence of gravity.

[0037] The above scheme is adopted: by separating the seedlings into conical seedling pots composed of seedling pot 1 310, seedling pot 2 312 and seedling pot 3 313, the problem of root entanglement of different seedlings is avoided, ensuring that the root system of each seedling has enough space to grow. Through the synergistic effect of the conical constraint of the closing hole 37 and the elastic deformation of the spring 36, the seedling pots can be automatically closed or opened. When closed, the maximum diameter matches the closing hole 37 to ensure airtightness. When opened, the hinged seedling pot 2 312 and seedling pot 3 313 hang down naturally to avoid damage to the mature root system.

[0038] Reference Figures 7 to 10The irrigation component 4 includes a water storage tank 41 and a water storage tank 42 that are connected through the water channel 38. The water storage tank 41 and the water storage tank 42 are symmetrically distributed on both sides of the lower fixed plate 317 and are fixedly connected to the lower fixed plate 317. A fixed frame 411 is fixedly connected to the side of the upper fixed plate 32. Two sets of fixed frames 411 are provided and are symmetrically distributed on both sides of the upper fixed plate 32. The water storage tank 41 and the water storage tank 42 are slidably inserted into one set of fixed frames 411 respectively. The cross-section of the water storage tank 41 and the water storage tank 42 is T-shaped, and the fixed frame 411 is U-shaped. A water inlet 43 is connected through the side of the water storage tank 41. One end of the water inlet 43 is connected through the side of the water storage tank 42. A limit plate 44 is fixedly connected to the top of the inside of the water channel 38. A slidably inserted part is inserted into the limit plate 44. A connecting rod 45 is fixedly connected to a limiting block 46 on its outer side. Two sets of limiting plates 44 are symmetrically distributed on both sides of the limiting block 46. A sealing block 47 is fixedly connected to the end face of the connecting rod 45. Two sets of sealing blocks 47 are symmetrically distributed at both ends of the connecting rod 45. The two sets of sealing blocks 47 are slidably inserted into the outlets of water tank 1 41 and water tank 2 42, respectively. One side of the top of the sealing block 47 is arc-shaped. A set of water inlet grooves 48 is opened at the bottom of the outlet of water tank 1 41 and water tank 2 42. The cross-section of the water inlet groove 48 is triangular, and the top width of the water inlet groove 48 is greater than the bottom width of the sealing block 47. A rotating rod 49 is rotatably connected to the inner side of the base 1. A gear 2 410 is fixedly connected to the outer side of the rotating rod 49. Two sets of gear 2 410 are provided. Each set of gears 410 meshes with a set of gears 31. The output end of the motor 2 passes through the base 1 and is fixedly connected to the rotating rod 49. The water inlet component 43 includes a water inlet pipe 432 that is connected to the water storage tank 41 and a water inlet pipe 433 that is connected to the water storage tank 42. The water inlet pipe 432 is connected to a diverter cylinder 431. The water inlet pipe 433 is connected to the diverter cylinder 431. The water inlet pipe 432 and the water inlet pipe 433 are symmetrically distributed on both sides of the diverter cylinder 431. The water inlet pipe 432, the water inlet pipe 433 and the diverter cylinder 431 are Y-shaped. The water inlet of the diverter cylinder 431 is higher than the connection point between the water inlet pipe 432 and the water inlet pipe 433 and the water storage tank 41 and the water storage tank 42. The bottom of the diverter cylinder 431 is fixed inside. A diversion plate 434, which is triangular prism-shaped, is connected to the connection point of inlet pipe 432, inlet pipe 433, and diversion cylinder 431. The diversion plate 434 diverts the liquid entering the diversion cylinder 431, ensuring even distribution so that the liquid flows into inlet pipes 432 and 433 respectively. The pouring component 4 injects liquid through the inlet at the top of the Y-shaped diversion cylinder 431, which is then evenly distributed to inlet pipes 432 and 433 via the triangular prism diversion plate 434. This allows the symmetrical water storage tanks 41 and 42 to simultaneously store water. After impacting the float plate 55, the liquid seeps into the bottom of the tank through its drain hole. As the water level rises, the float plate 55 is lifted by buoyancy, revealing the water outlet. At this time, the increased weight of the symmetrical water storage tanks causes the fixing lug 35 to press down the spring 36.The trigger water flow component 33 moves downward as a whole. The sealing block 47 inside the outlet of the dual water tank remains stationary due to the balanced water pressure on both sides. When the device is driven to rotate by motor 2, the sealing block 47 of the lower water tank is pushed by water pressure and slides through connecting rod 45, connecting the triangular inlet channel 48 with the water flow channel 38 to form the main irrigation channel. The sealing block 47 of the higher water tank partially retracts, creating a slow-flow gap. Limiting plate 44 and limiting block 46 cooperate to maintain a stable flow rate. The water in the water flow channel 38 is continuously supplied to the seedling pots through the capillary action of the mountain-shaped suction rope 311. When the water level drops to a critical value, float 55 moves downward, triggering guide block two 510 to engage with guide block three 511, releasing the restriction of locking component 5, and the sealing block 47 resets, completing the irrigation cycle.

[0039] The above solution, through the diversion cylinder 431 and the diversion plate 434, can accurately and evenly distribute the irrigation liquid to the two water tanks, ensuring that the water volume in the two tanks is always equal, thus guaranteeing the correct implementation of subsequent functions. Utilizing the design of the float plate 55 and the sealing 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, eliminating the need for frequent manual operation and greatly saving labor costs. Moreover, this slow and stable liquid outflow method can ensure that the seedlings continuously and appropriately absorb water, avoiding the soil being washed away or the seedling roots being damaged due to excessive water flow, thus effectively improving the efficiency and quality of seedling cultivation.

[0040] Reference Figures 11 to 12The locking component 5 includes a rotating shaft 51 that passes through and is rotatably connected to the fixing lug 34. 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 opened through the top of the fixing lug 34, and a gear 54 is fixedly connected through the through hole 53. The through hole 53 is U-shaped. A limiting block 512 is fixedly connected to the side of the rotating rod 52. Two sets of limiting blocks 512 are symmetrically distributed on the side of the rotating rod 52. The cross-sectional area of ​​the limiting blocks 512 and the rotating rod 52 is the same as the size of the through hole 53. A float plate 55 is slidably connected inside the water tank 42. Multiple sets of drainage holes are opened through the float plate 55 to allow the liquid to flow below the float plate 55. A through hole 2 56 is provided at the top of plate 55. A rotating rod 2 57 is rotatably connected to the bottom of the interior of water tank 2 42. A gear 4 58 is fixedly connected to the top of rotating rod 2 57, and gear 4 58 meshes with gear 3 54. A guide block 1 59 and a guide block 2 510 are fixedly connected to the outer side of rotating rod 1 52. Guide blocks 1 59 and 2 510 are the same size and are spiral-shaped. Two sets of guide blocks 1 59 and 2 510 are provided, symmetrically distributed on the outer side of rotating rod 1 52. A guide block 3 511 is fixedly connected to the inner wall of through hole 2 56. Two sets of guide blocks 3 511 are provided, symmetrically distributed on the inner wall of through hole 2 56, which is spiral-shaped. Furthermore, guide block 3 511 is adapted to guide block 1 59 and guide block 2 510 respectively. Under the guidance of guide block 3 511 and guide block 1 59 or guide block 2 510, rotating rod 2 57 rotates 90 degrees. Locking parts 5 are provided in four sets, symmetrically distributed on both sides of the upper fixed plate 32. Water tank 1 41 is also provided with float plate 55, through hole 2 56, rotating rod 2 57, gear 4 58, guide block 1 59, guide block 2 510 and guide block 3 511. Water tank 1 41 and water tank 2 42 are each provided with two sets of through hole 2 56, rotating rod 2 57 and gear 4 58, symmetrically distributed at the top of float plate 55. When the pouring liquid is poured into the diversion cylinder 431, as the liquid in water tank 1 41 and water tank 2 42 increases, the weight increases. This causes the fixed lug 2 35 to move downwards, and the spring 36 to extend. At this time, the rotating shaft 51, which passes through the fixed lug 2 35 and is connected to the rotating rod 1 52, moves accordingly. The limiting block 512 moves below the fixed lug 1 34 through the through hole 1 53. When the float 55 moves upwards due to the increase of liquid in the water tank, the guide block 3 511 on the inner wall of the through hole 2 56 at the top of the float 55 abuts against the guide block 1 59 on the outer side of the rotating rod 1 52. Due to their spiral structure, the rotating rod 2 57 rotates 90 degrees under the guidance of the cooperation. Through the meshing of gear 4 58 and gear 3 54, the rotating rod 1 52 also rotates 90 degrees, causing the limiting block 512 to be misaligned with the through hole 1 53. This achieves the restriction of the water flow component 33, preventing it from prematurely returning to its initial state due to the subsequent decrease in gravity.When the liquid in the water tank decreases, the float 55 moves down to abut against the arc surface of the sealing block 47, pushing the sealing block 47 back to its initial state of blocking the outlet. At this point, the guide block 510 on the outside of the rotating rod 52 inserts into the through hole 56 and abuts against the guide block 511, causing the rotating rod 57 to rotate 90 degrees again. Through gear transmission, the rotating rod 52 rotates 90 degrees, and the limiting block 512 realigns with the through hole 53, releasing the restriction on the water flow component 33, allowing the spring 36 to drive the water flow component 33 upwards.

[0041] The above solution effectively prevents the water flow component 33 from moving arbitrarily due to changes in the weight of the liquid in the water tank during the early stage of seedling cultivation. This ensures that the seedling pot remains stably closed, providing a good initial growth environment for the seedlings and preventing them from being disturbed by external factors due to premature opening and closing of the pot. During the liquid reduction stage, its precise unlocking mechanism, in conjunction with the liquid volume in the water tank and the position of the float 55, appropriately releases the restriction on the water flow component 33, allowing it to move upward under the action of the spring 36, thus separating the seedling pot and facilitating the subsequent removal of the seedlings. This greatly improves the automation level and operational reliability of the entire cultivation device and reduces the complexity and error probability of manual intervention.

[0042] The working principle of this invention is as follows: First, the irrigation liquid is poured into the distribution cylinder 431. The triangular prism-shaped distribution plate 434 inside the cylinder is located at the connection point between the first water inlet pipe 432, the second water inlet pipe 433, and the distribution cylinder 431, which can evenly distribute 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 tanks first falls on the float plate 55 with multiple sets of drainage holes, and then flows to the bottom of the float plate 55 through the drainage holes. As the liquid continues to increase, the float plate 55 gradually moves upward due to buoyancy, and the outlets of the first water storage tank 41 and the second water storage tank 42 are exposed. Due to the action of the distribution plate 434, the liquid volume in the two water storage tanks is always the same, and the water storage tanks are located at the bottom. The liquid thrust on the sides of the two sets of sealing blocks 47 inside the outlets of tank 41 and tank 42 is consistent, thus keeping the sealing blocks 47 balanced and stable inside the outlets. Simultaneously, the increased weight of tanks 41 and 42 due to the increased liquid causes the fixing lug 35 to move downwards, extending the spring 36. During this process, the limiting block 512 moves through the through hole 53 below the fixing lug 34 until the T-shaped tanks 41 and 42 respectively abut against a set of fixing frames 411. At this point, the fixing lug 35 moves to its limit position, and the water flow component 33 also moves to its limit position simultaneously, thereby driving the seedling pots 310, 312, and 313 downwards. Under the constraint of the conical inner wall of the closing hole 37, the seedling pot 310… Seedling pots 2 (312) and 3 (313) gradually close. Then, the float 55 continues to move upwards until guide block 1 (59) enters through hole 2 (56) and abuts against guide block 3 (511). Due to the spiral contact surface of guide block 1 (59) and guide block 3 (511), rotating rod 2 (57) rotates 90 degrees. Through the meshing of gears 4 (58) and 3 (54), rotating rod 1 (52) also rotates 90 degrees, causing the limiting block 512 to misalign with through hole 1 (53), thus restricting the water flow component 33. This prevents the spring 36 from prematurely restoring the opening / closing state due to subsequent weight reduction. Liquid addition is now complete. After liquid addition, soil is filled into the closed seedling pots, and sweet potato seedlings are planted. Then, motor 2 is started, and the output of motor 2 drives rotating rod 49 to rotate. As gears 31 and 410 mesh, the upper fixing plate 32 begins to rotate, and the planting component 3 and the irrigation component 4 rotate synchronously to ensure that the seedlings in the seedling pots always receive sunlight. During the rotation, the symmetrically distributed water storage tanks 41 and 42 will tilt. When the outlet of water storage tank 42 or water storage tank 41 tilts to a lower position, the other side of the outlet of water storage tank 41 or water storage tank 42 tilts to a higher position. The balance of the two sets of sealing blocks 47 is broken. The liquid thrust on the sealing block 47 in water storage tank 41 or water storage tank 42 with the outlet tilted to a lower position increases, while the thrust on the sealing block 47 on the other side decreases, causing the connecting rod 45, the limiting block 46, and the sealing block 47 to slide to a lower position.Until the limiting block 46 abuts against the limiting plate 44, at this point, the triangular water inlet trough 48 at the bottom of the lower set of closed blocks 47 is connected to the inside of the water storage tank and the water flow trough 38 respectively. The upper set of closed blocks 47 partially detaches from the outlet of the water storage tank, creating a gap with the outlet. Liquid then slowly flows out of the water storage tank and flows through the water flow trough 38 to another set of water storage tanks. Due to the action of the limiting block 46 and the limiting plate 44, regardless of the change in tilt angle, the liquid can be ensured to flow out slowly. The liquid flowing in the water flow trough 38 is sucked into the soil in the seedling pot by the mountain-shaped water absorption rope 311 for the seedlings to absorb. As the liquid in water storage tank 1 41 or water storage tank 2 42 gradually decreases, under the restriction of the limiting block 512, even if water storage tank 1 41 or water storage tank 2 42... The weight of the second tank 42 is less than the elastic force of the spring 36, so they cannot move upwards to reset until the float 55 moves downwards to abut against the arc surface of the sealing block 47, pushing out the sealing block 47 in the outlet of the first water tank 41 or the second water tank 42. The two sets of sealing blocks 47 return to their initial state and return to the outlets of the first water tank 41 and the second water tank 42, respectively. 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 the spiral abutment surface of the two, the rotating rod 2 57 rotates 90 degrees. With the help of the meshing action of the gear 4 58 and the gear 3 54, the rotating rod 1 52 also rotates 90 degrees. The limiting block 512 is realigned with the through hole 1 53. At this time, the spring 36 is no longer restricted, returns to its original length, and drives the water flow component 33 to move upwards. The seedling pots are pushed out of the closed hole 37. Freed from the constraint of the closed hole 37, seedling pots 312 and 313 hinge and rotate under gravity, separating the seedling pots. Since the seedling roots have already fixed the soil, the seedlings can be directly removed from the seedling pots after separation. The planting element 3 separates the seedlings into conical seedling pots composed of seedling pot 310, seedling pot 312, and seedling pot 313, preventing root entanglement between different seedlings and providing ample growth space for each seedling. The conical constraint of the closed hole 37 and the elastic deformation of the spring 36 work together to automatically close or open the seedling pots. When closed, the maximum diameter matches the closed hole 37, ensuring good sealing. When opened, the hinged seedling pot 312... The seedlings in pots 312 and 313 hang naturally, preventing damage to the mature root system. Liquid is injected through the top inlet of the diversion cylinder 431 in the irrigation component 4, and then precisely and evenly distributed to the symmetrical water storage tanks 41 and 42 via the triangular prism diversion plate 434, ensuring that the water volume in both tanks is always equal and guaranteeing the normal operation of subsequent functions. The float plate 55 and the sealing block 47 can automatically control the liquid flow based on the liquid volume in the water storage tanks and the tilt of the device, eliminating the need for frequent manual operation and saving a lot of labor costs. Moreover, this slow and stable liquid flow method ensures that the seedlings continuously and appropriately absorb water, effectively preventing damage to the seedling roots due to excessive water flow, and significantly improving the efficiency and quality of seedling cultivation. The locking component 5 is used in the early stage of seedling cultivation.It effectively prevents the water flow component 33 from moving arbitrarily due to changes in the weight of the liquid in the water tank, ensuring that the seedling pot remains stably closed and creating a favorable initial growth environment for the seedlings. During the liquid reduction phase, its precise unlocking mechanism closely matches the liquid level in the water tank and the position of the float 55, appropriately releasing the restriction on the water flow component 33. This allows the water flow component 33 to move upwards under the action of the spring 36, smoothly separating the seedling pot and facilitating subsequent seedling removal. This significantly improves the automation level and operational reliability of the entire cultivation device, reducing the complexity and error probability of manual intervention.
