Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a seedling transplanter. Background Technology

[0002] Traditionally, when transplanting seedlings, seedling trays are dug beforehand, and then the seedlings are transplanted one by one into the trays. This ensures that the seedlings are spaced appropriately, allowing for better water absorption and photosynthesis, thus helping them grow strong. However, because the number of seedlings transplanted is usually large, manual transplanting has the following main disadvantages.

[0003] 1. Low efficiency and damage to seedlings: Traditional methods require removing seedlings one by one from the seedling tray, manually loosening the soil at the bottom of the seedbed with a small hoe before planting the seedlings, and then manually backfilling the soil to cover them. This process is labor-intensive, slow, and it is difficult to ensure that the backfilling soil is evenly compacted, which can easily lead to damage to the seedling roots or loose soil covering, affecting the survival rate.

[0004] 2. Existing transplanting equipment has limited functionality: While transplanting equipment is available on the market to assist in seedling collection and planting, it generally lacks an integrated backfill soil control mechanism. For example, some devices only perform the function of opening holes or planting seedlings, still requiring manual completion of soil covering and compaction. This results in unstable backfill soil compaction and seedling fixation, making it difficult to adapt to different soil moisture requirements.

[0005] 3. Poor water control precision and serious water waste: Traditional irrigation requires external water pipes for flood irrigation after transplanting, which has two major drawbacks: Insufficient water control: It is impossible to accurately adjust the amount of irrigation according to the water needs of seedlings, which easily leads to drought or waterlogging problems; Low water resource utilization: Ineffective seepage and surface runoff in the flood irrigation mode lead to a large amount of water loss, especially in hilly and mountainous areas such as Yunnan, Guizhou and Sichuan, where the undulating terrain exacerbates the problem of uneven water use.

[0006] 4. Limited Promotion of Mechanized Equipment: While large-scale transplanting machinery can improve efficiency, its purchase and maintenance costs are high, and it has strict requirements on plot size and terrain flatness. my country's flue-cured tobacco planting areas (such as Yunnan, Guizhou, and Sichuan) are mostly scattered small-area terraced fields or slopes, which are difficult to apply to large-scale mechanized operations, resulting in a low adoption rate of existing technologies.

[0007] In summary, existing technologies suffer from functional fragmentation, inefficient water control, and poor cost adaptability, making it difficult to meet the needs of efficient, water-saving, and low-damage transplanting in small-scale planting scenarios. Therefore, there is an urgent need to develop an integrated device that combines seedling collection, backfilling, and precise watering to reduce reliance on manual labor and improve transplanting quality.

[0008] The purpose of this invention is to provide a seedling transplanter that can solve at least one of the technical problems in the background art.

[0009] To achieve the above objectives, this utility model provides a seedling transplanter, including a drilling device and an irrigation device connected to a positioning component; the seedling transplanter also includes a seedling storage cylinder, fixedly connected to the positioning component, wherein the seedling outlet of the seedling storage cylinder is provided with a pressure plate, the pressure plate being rotatably connected to the seedling storage cylinder to close and open the seedling outlet; the drilling device is movably connected to the positioning component via a sliding structure to move vertically under force; the water inlet of the irrigation device is connected to a water source, and the water outlet is positioned opposite to the seedling outlet for irrigating seedlings in the base soil.

[0010] In one possible design, the positioning element includes a positioning rod and a smooth rod arranged in parallel, with the upper and lower ends of the positioning rod connected to the smooth rod via positioning plates; the irrigation device and the seedling storage cylinder are both fixedly connected to the positioning rod.

[0011] The sliding structure includes a base and a bushing. The bushing is fitted onto the guide rod, and the drilling device is fixedly connected to the bushing via the base.

[0012] In one possible design, the base is provided with a control assembly; the control assembly includes a fixed handle, a movable handle, a spring, a first linkage assembly, and a locking rod. The fixed handle is fixedly connected to the base; the movable handle is located below the fixed handle and is rotatably connected to the fixed handle via a pin; one end of the spring is connected to the lower end of the base, and the other end is connected to the movable handle; one end of the first linkage assembly is fixedly connected to the pin, and the other end is provided with a locking plate, which is disposed opposite to a positioning plate located at the upper end of the positioning rod, and the locking plate is provided with a locking groove that mates with the positioning plate;

[0013] When the movable handle is pulled upward, the first linkage assembly rotates with the pin, causing the locking plate to rotate and move away from the positioning plate, thereby releasing its vertical lock with the positioning plate; when the movable handle is released, the movable handle resets under the force of the spring, and the locking plate rotates and gradually moves closer to the positioning plate to lock onto the positioning plate.

[0014] In one possible design, the seedling storage cylinder is provided with a mounting shaft, and a torsion spring is sleeved on the mounting shaft; the pressure plate is provided with an L-shaped mounting seat, and the mounting seat is provided with a lever; one end of the torsion spring presses against the seedling storage cylinder, and the other end presses against the mounting seat;

[0015] The positioning rod of the positioning component is provided with a positioning shaft, and the positioning shaft is provided with a rotatable moving pressure plate. The lever is rotatably connected to the moving pressure plate. The base is provided with a support arm for pressing against the moving pressure plate. When the base moves upward, the support arm can press against the moving pressure plate, causing the pressure plate to open. When the pressure on the moving pressure plate disappears, the mounting base returns to its original position under the action of the torsion spring, causing the pressure plate to close.

[0016] In one possible design, the end of the pressure plate is provided with a rotatable roller, which partially overlaps the support arm in the horizontal direction, so that the support arm can press against the roller when it moves.

[0017] In one possible design, the mounting base is provided with a mounting groove for receiving the end of the torsion spring.

[0018] In one possible design, the lower end of the fixed handle is provided with a drilling switch, which is electrically connected to the drilling device so that the drilling device can be rotated when the movable handle touches the drilling switch.

[0021] In one possible design, the seedling transplanter also includes a support frame located below and fixedly connected to the positioning element, with the drill bit of the drilling device disposed in the annular cavity of the support frame.

[0022] The operator moves the transplanter to the preset planting point and uses external force to drive the drilling device down the sliding structure, forming planting holes in the base soil that match the size of the tobacco seedling roots. After drilling is completed, the drilling device returns to its initial position. A single seedling is pre-stored in the seedling storage cylinder. Once the planting hole is formed, the operator rotates the pressure plate around the storage cylinder to open the seedling outlet, allowing the seedling to fall precisely into the planting hole under gravity. The pressure plate then rotates in the opposite direction to close the outlet. The water outlet of the irrigation device corresponds to the seedling outlet. After the seedling is planted, water is metered into the planting hole through the irrigation device, with the water flow directly acting on the root zone of the seedling, avoiding the water wastage caused by traditional flood irrigation.

[0023] Through the above technical solution, drilling, seedling placement, soil covering, and watering are completed in one mechanical operation, reducing manual operation and significantly shortening the transplanting time per seedling. The pressure plate also functions as the opening and closing mechanism for the seedling outlet, ensuring the seedling stands upright and stably. The irrigation device's water outlet is directly aligned with the planting hole, and with a quantitative water supply design (such as a flow controller or pulse injection), precise irrigation is achieved on demand, reducing the loss of ineffective water resources. Addressing the rapid water infiltration characteristic of sloping terrain in the Yunnan-Guizhou-Sichuan region, directional irrigation maintains soil moisture around the roots and prevents surface runoff. The use of simple mechanical components such as a sliding structure and pressure plate eliminates the need for a complex power system, reducing manufacturing costs and maintenance difficulty. This small-scale seedling transplanting equipment has a lightweight overall structure, adapting to terraced fields, slopes, and other terrain conditions, overcoming the dependence of large machinery on the size and flatness of the land plot.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the present invention, it does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0031] According to a specific embodiment of this utility model, a seedling transplanter is provided. Figures 1 to 4 One specific embodiment is shown.

[0032] See Figures 1 to 4 As shown, the seedling transplanter includes a drilling device 2 and an irrigation device 3 connected to the positioning component 1. The seedling transplanter also includes a seedling storage cylinder 41, which is fixedly connected to the positioning component 1. The seedling outlet of the seedling storage cylinder 41 is provided with a pressure plate 42, which is rotatably connected to the seedling storage cylinder 41 to close and open the seedling outlet. The drilling device 2 is movably connected to the positioning component 1 through a sliding structure to move vertically under force. The water inlet of the irrigation device 3 is connected to a water source, and the water outlet is set opposite to the seedling outlet for irrigating the seedlings in the base soil.

[0033] The operator moves the transplanter to the preset planting point and drives the drilling device 2 to move down along the sliding structure using external force, forming planting holes in the base soil that match the size of the tobacco seedling roots. After drilling is completed, the drilling device 2 returns to its initial position. A single seedling is pre-stored in the seedling storage cylinder 41. Once the planting hole is formed, the operator rotates the pressure plate 42 around the storage cylinder 41 to open the seedling outlet, allowing the seedling to fall precisely into the planting hole under gravity. The pressure plate 42 then rotates in the opposite direction to close the seedling outlet, awaiting the manual placement of the next seedling. The water outlet of the irrigation device 3 corresponds to the seedling outlet. After the seedling is planted, water is metered into the planting hole through the irrigation device 3, with the water flow directly acting on the root zone of the seedling, avoiding the water wastage caused by traditional flood irrigation.

[0034] Through the above technical solution, drilling, seedling placement, soil covering, and watering are completed in one go via mechanical linkage, reducing manual operation and significantly shortening the transplanting time per seedling. The pressure plate 42 also functions as the opening and closing port for the seedling emergence, and its conical shape ensures the seedling remains upright and stable. The irrigation device 3's water outlet is directly aligned with the planting hole, and with a quantitative water supply design (such as a flow controller or pulse injection), precise irrigation is achieved on demand, reducing the loss of ineffective water resources. Addressing the rapid water infiltration characteristic of sloping terrain in the Yunnan-Guizhou-Sichuan region, directional irrigation maintains soil moisture around the roots and prevents surface runoff. The use of simple mechanical components such as a sliding structure and pressure plate 42 eliminates the need for a complex power system, reducing manufacturing costs and maintenance difficulty. This small-scale seedling transplanting equipment has a lightweight overall structure, adapting to terraced fields, slopes, and other terrain conditions, overcoming the dependence of large machinery on the size and flatness of the land plot.

[0035] Specifically, the positioning component 1 includes a positioning rod 11 and a smooth rod 12 arranged in parallel. The upper and lower ends of the positioning rod 11 are connected to the smooth rod 12 through positioning plates, respectively. The positioning component 1 is composed of the positioning rod 11 and the smooth rod 12 arranged in parallel. The upper and lower ends of the two form a rigid frame through the positioning plate to ensure that the space of the drilling device 2, the seedling storage cylinder 41 and the irrigation device 3 is relatively fixed.

[0036] Irrigation device 3 and seedling storage cylinder 41 are both fixedly connected to positioning rod 11; the sliding structure includes base 61 and bushing 62, with bushing 62 fitted onto smooth rod 12, and drilling device 2 fixedly connected to bushing 62 via base 61. Before operation, the transplanter is moved to the planting point. Positioning rod 11 serves as the main support, and the seedling storage cylinder 41, irrigation device 3, and drilling device 2 in the sliding structure form a vertical working axis, ensuring the coordination of the actions of each component. The operator applies external force to drilling device 2, driving base 61 to slide bushing 62 along smooth rod 12, causing drilling device 2 to move downwards vertically, forming a planting hole of controllable depth in the base soil. The sliding fit between the smooth rod 12 and the bushing 62 provides linear guidance, avoids drilling deviation, ensures the verticality of the planting hole, and adapts to the growth needs of the seedling roots. After drilling is completed, the external force is removed, and the drilling device 2 slides up and resets along the smooth rod 12 under the action of gravity or a reset mechanism (such as spring 53), so as to avoid hindering the subsequent seedling planting action.

[0037] The seedling storage cylinder 41 is fixed to the positioning rod 11, with its seedling outlet facing the planting hole, and contains a single seedling. By rotating the pressure plate 42, the seedling outlet is opened, and the seedling falls precisely into the hole. Then, the pressure plate 42 rotates in the opposite direction to close the seedling outlet. Its rotational trajectory pushes the soil around the planting hole backfill, completing the soil covering and compaction. The irrigation device 3 is fixed to the positioning rod 11, with its water outlet aligned with the seedling outlet. After the seedling is planted, the water flows directly into the bottom of the planting hole, avoiding water diffusion and waste caused by traditional flood irrigation.

[0038] Positioning rod 11 and smooth rod 12 form a double-track parallel frame through a positioning plate, significantly improving the overall rigidity of the equipment, resisting lateral forces during drilling, and avoiding positioning deviations caused by device swaying. The precise fit between bushing 62 and smooth rod 12 in the sliding structure ensures linear movement of the drilling device 2, avoiding the tilting problem common in manual operation, and guaranteeing that the verticality of the planting hole is ≤3°, meeting the requirements for upright seedling planting. Targeted irrigation reduces water consumption per plant to 30%-40% of traditional flood irrigation, especially in sloping terrain, reducing water loss due to runoff by more than 50%.

[0039] Furthermore, a control assembly 5 is provided on the base 61; the control assembly 5 includes a fixed handle 51, a movable handle 52, a spring 53, a first linkage assembly 54, and a locking rod 55. The fixed handle 51 is fixedly connected to the base 61; the movable handle 52 is located below the fixed handle 51 and is rotatably connected to the fixed handle 51 via a pin; one end of the spring 53 is connected to the lower end of the base 61, and the other end is connected to the movable handle 52; one end of the first linkage assembly 54 is fixedly connected to the pin, and the other end is provided with a locking plate, which is opposite to the positioning plate located at the upper end of the positioning rod 11, and the locking plate is provided with a slot that cooperates with the positioning plate. When the movable handle 52 is pulled upward, the first linkage assembly 54 can rotate with the pin, and the locking plate can rotate and move away from the positioning plate to release its vertical locking with the positioning plate; when the movable handle 52 is released, the movable handle 52 resets under the force of the spring 53, the locking plate rotates and gradually moves closer to the positioning plate to lock onto the positioning plate.

[0040] When not in operation, the tension of spring 53 keeps the movable handle 52 pressed tightly against the fixed handle 51. The first linkage assembly 54 drives the slot on the clamping plate to form a vertical mechanical engagement with the positioning plate at the upper end of the positioning rod 11, preventing the bushing 62 from sliding along the smooth rod 12 and ensuring that the drilling device 2 is at a fixed height. When the operator pulls the movable handle 52 upward with one hand, the movable handle 52 rotates around the pin and stretches the spring 53. At the same time, the first linkage assembly 54 drives the clamping plate to rotate, causing the slot to disengage from the positioning plate and releasing the vertical lock on the sliding structure. At this time, the drilling device 2 can slide down the smooth rod 12 under the action of external force.

[0041] When the operator presses down on the drilling device 2, the bushing 62 moves down along the smooth rod 12, and the drill head cuts into the soil to form a planting hole. When the preset depth is reached (limited by the length of the smooth rod 12 or the position of the positioning plate), the movable handle 52 is released. The spring 53's rebound force drives the movable handle 52 to reset, and the locking plate rotates to re-engage the slot with the positioning plate, locking the drilling device 2 in the current position to ensure that the hole depth is consistent each time (error ≤ 2cm). After completing a single transplant, the operator pulls the movable handle 52 again to unlock it, manually raises the drilling device 2 to the initial height, and releases the handle. The locking plate automatically locks, preparing for the next transplant cycle.

[0042] Through the lever design of the movable handle 52 and spring 53, the operator can complete the entire process of unlocking, pressing down, and resetting with one hand, reducing the coordination difficulty of traditional two-handed operation. The spring 53 assists in resetting, reducing the force required to manually lift the drilling device 2, saving about 40% of physical exertion compared to purely manual operation. The mechanical engagement of the slot and the positioning plate forms a rigid stop, ensuring that the drilling depth deviation is ≤2cm for each hole (the traditional manual hole-opening depth deviation is generally >5cm), avoiding seedling lodging caused by too shallow planting holes or growth retardation caused by too deep holes. The preload of spring 53 maintains a normally locked state, preventing the drilling device 2 from accidentally sliding down during non-operational periods, thus improving safety. The control components 5 (fixed handle 51, movable handle 52, and connecting rod) are integrated into the side of the base 61, without any protruding complex mechanisms, avoiding collisions with surrounding crops or obstacles during field operations. The slot and positioning plate are made of hardened steel, and the contact surface can withstand ≥5000 locking-unlocking cycles, adapting to the needs of high-intensity continuous operation. Spring 53, pin, and connecting rod are all general-purpose mechanical parts, with extremely low replacement costs, making them suitable for rural users to repair themselves. Furthermore, the structural design of this seedling transplanter avoids the risks of electronic sensor or hydraulic system malfunctions, making it particularly suitable for the humid and rainy environment of the Yunnan-Guizhou-Sichuan region.

[0043] In one embodiment, the seedling storage cylinder 41 is provided with an installation shaft, and a torsion spring 44 is sleeved on the installation shaft; the pressure plate 42 is provided with an L-shaped mounting seat 45, and the mounting seat 45 is provided with a lever 46; one end of the torsion spring 44 presses against the seedling storage cylinder 41, and the other end presses against the mounting seat 45; the positioning rod 11 of the positioning member 1 is provided with a positioning shaft, and the positioning shaft is provided with a rotatable moving pressure plate, and the lever 46 is rotatably connected to the moving pressure plate; wherein, the base 61 is provided with a support arm for pressing against the moving pressure plate, and when the base 61 moves upward, the support arm can press against the moving pressure plate, so that the pressure plate 42 opens; when the pressure on the moving pressure plate disappears, the mounting seat 45 is reset under the action of the torsion spring 44, so that the pressure plate 42 closes.

[0044] When the base 61 moves upward, the support arm presses against the moving pressure plate, causing the moving pressure plate to rotate. This rotation, via the lever 46, causes the pressure plate 42 to open, opening the seedling outlet of the seedling storage cylinder 41. Under gravity or other auxiliary forces, the seedlings are moved out of the outlet and implanted into the pre-drilled holes. When the pressure on the moving pressure plate disappears, the mounting base 45 returns to its original position under the action of the torsion spring 44, and the pressure plate 42 closes, sealing the seedling outlet of the seedling storage cylinder 41, preparing for the next transplanting.

[0045] The automatic opening and closing of the pressure plate 42 is achieved through the linkage mechanism of the upward movement of the base 61 and the moving pressure plate, further improving the automation level of the transplanting process and reducing the complexity of manual operation. The opening and closing of the pressure plate 42 is precisely controlled by the linkage mechanism of the torsion spring 44 and the moving pressure plate, ensuring the stability and accuracy of the seedlings during the transplanting process and avoiding seedling damage caused by improper operation.

[0046] Specifically, the end of the pressure plate 42 is provided with a rotatable roller 48, which partially overlaps with the support arm in the horizontal direction so that the support arm can press against the roller 48 when it moves. When the base 61 moves upward, the support arm presses against the moving pressure plate, the moving pressure plate rotates, and the pressure plate 42 is opened by the lever 46, opening the seedling outlet of the seedling storage cylinder 41. The seedlings are moved out of the seedling outlet under gravity or other auxiliary forces and planted into the pre-drilled holes.

[0047] The end of the pressure plate 42 is equipped with a rotatable roller 48, which partially overlaps with the support arm in the horizontal direction. When the support arm moves, it presses against the roller 48, further ensuring a smoother and more stable opening action of the pressure plate 42. When the pressure on the moving pressure plate disappears, the mounting base 45 resets under the action of the torsion spring 44, the pressure plate 42 closes, and the seedling outlet of the seedling storage cylinder 41 is sealed, ready for the next transplanting.

[0048] In one embodiment provided in this disclosure, the mounting base 45 is provided with a mounting groove for accommodating the end of the torsion spring 44, which can effectively limit the position of the torsion spring 44, so that it can be better constrained, ensure that the elastic force can be effectively transmitted, and further improve the stability and reliability of the transplanting process.

[0049] In one embodiment provided in this disclosure, a drilling switch 71 is provided at the lower end of the fixed handle 51. The drilling switch 71 is electrically connected to the drilling device 2 so that when the movable handle 52 touches the drilling switch 71, the drilling device 2 can be rotated.

[0050] The drilling switch 71 is located at the lower end of the fixed handle 51. While holding the fixed handle 51, the operator can easily touch the drilling switch 71 with their other hand to start the drilling device 2, eliminating the need for additional manual operation or complex control devices, thus improving the convenience and smoothness of operation. The drilling device 2 is immediately started when the movable handle 52 touches the drilling switch 71, reducing operational delay and enabling rapid response in drilling operations, thereby improving work efficiency.

[0051] The drilling device 2 is activated by touching the drilling switch 71 with the movable handle 52, ensuring that drilling operations are performed at precise locations and times. Operators can accurately control the start and end of drilling as needed, avoiding unnecessary drilling or deviations in drilling position. The linkage design between the drilling switch 71 and the movable handle 52 ensures that the drilling device 2 only activates when the movable handle 52 is touched, reducing the possibility of misoperation. When drilling is not required, the movable handle 52 will not touch the drilling switch 71, and the drilling device 2 remains stationary, improving operational safety and reliability.

[0052] The operator can activate the drilling device 2 at any time by touching the drilling switch 71 while moving the transplanter, enabling continuous drilling operations without the need for frequent manual opening and closing of the drilling device 2, thus improving the efficiency of the entire transplanting process. Combining the drilling switch 71 with the movable handle 52 simplifies the operation process, reduces the number of steps required from the operator, and makes the entire transplanting process more efficient.

[0053] In this disclosure, a touch arm 63 is provided on the base 61, and a water outlet switch 72 corresponding to the touch arm 63 is provided on the positioning plate located at the upper end of the smooth rod 12. The water outlet switch 72 is connected to the irrigation device 3. When the base 61 moves to a predetermined position, the touch arm 63 will touch the water outlet switch 72. This touch action will trigger the irrigation device 3 to start working, thereby achieving precise irrigation of the seedlings. This automated control method can ensure timely provision of water to the seedlings during the critical period after transplanting, which is beneficial to the survival and growth of the seedlings.

[0054] By coordinating the touch arm and the water outlet switch 72, the irrigation device 3 is activated only when irrigation is needed, avoiding the waste of water resources in traditional watering methods. When watering is not needed, the water outlet switch 72 is in the closed state, preventing water from flowing away and improving the efficiency of water resource utilization.

[0055] In this way, the combination of the touch arm and the water outlet switch 72 allows the three steps of drilling, transplanting, and irrigation to work more closely together. During transplanting, once the seedling is planted in the base soil, the touch arm immediately triggers the water outlet switch 72 to irrigate, completing the entire process seamlessly and greatly improving transplanting efficiency. The water outlet switch 72 is connected to the irrigation device 3, ensuring uniform irrigation. Compared to traditional manual watering, this automated irrigation method delivers water more evenly to the seedling roots, avoiding uneven seedling growth caused by uneven watering and improving transplanting quality.

[0056] In this disclosure, the irrigation device includes a solenoid valve and a water pump. The solenoid valve controls the flow of water in the pipeline, while the outlet switch controls the operating status of the water pump. Therefore, when seedlings need to be irrigated, both the solenoid valve and the outlet switch need to be activated simultaneously to irrigate the seedlings. After irrigation is completed, the solenoid valve can be closed to block the water source, thereby reducing water waste.

[0057] In one embodiment of this disclosure, a guide cylinder 43 is provided below the seedling storage cylinder 41. The guide cylinder 43 is inclined and fixedly connected to the positioning member 1. The inclined arrangement of the guide cylinder 43 provides a smooth path for the seedlings to be removed. When the pressure plate 42 opens and the seedling is removed from the seedling outlet of the seedling storage cylinder 41, the guide cylinder 43 can guide the seedling smoothly into the pre-drilled hole along its inclined direction, avoiding jamming or deviation of the seedling during removal and ensuring that the seedling is accurately planted in the base soil. By adjusting the inclination angle and length of the guide cylinder 43, it can adapt to the transplanting needs of different depths. Under different soil conditions and planting requirements, the transplanting depth of the seedlings can be flexibly adjusted to ensure that the seedlings grow at a suitable depth, which is beneficial to improving the survival rate and growth quality of the seedlings.

[0058] The guide tube 43 facilitates smoother seedling removal, reducing time delays caused by seedling jamming or misalignment. Operators can complete the transplanting operation more quickly, thus improving the overall efficiency of the process. Furthermore, it ensures seedling stability during transplanting, preventing quality degradation due to seedling swaying or tilting. Guided by the guide tube 43, the seedlings are planted into the soil in the correct orientation, promoting root contact and growth, and ultimately improving transplant quality.

[0059] In this disclosure, the guide cylinder 43 is made of stainless steel. The guide cylinder 43 reduces direct friction between the seedlings and the seedling storage cylinder 41 and other components, thus reducing wear and tear. Simultaneously, the guide cylinder 43 itself can withstand a certain amount of friction, protecting other critical components, extending the service life of the equipment, and improving its reliability and economy.

[0060] In one embodiment, the seedling transplanter further includes a support frame 8, which is located below and fixedly connected to the positioning element 1. The drill bit of the drilling device 2 is disposed in the annular cavity of the support frame 8. The support frame 8 provides a stable support platform for the drilling device 2, enabling it to maintain a stable state during operation. Since the support frame 8 is fixedly connected to the positioning element 1, it effectively reduces the shaking and vibration of the drilling device 2 during drilling, thereby improving the accuracy and quality of drilling. The drill bit, disposed in the annular cavity of the support frame 8, provides guidance and constraint to the drill bit, allowing it to move along a predetermined trajectory during drilling, further improving the accuracy and consistency of drilling. This design helps ensure that the position and depth of the drill holes meet the requirements, providing accurate holes for seedling transplantation.

[0061] Furthermore, the support frame 8 isolates the drilling device 2 from the external environment, reducing interference and damage from external factors during use. For example, during the movement or storage of the transplanter, the support frame 8 prevents the drilling device 2 from colliding with other objects, protecting the drill bit from damage. The support frame 8 also protects the drilling device 2, reducing wear and damage and extending its service life. This not only reduces maintenance costs but also improves the reliability and economy of the equipment.

[0062] In this disclosure, the drilling device is configured as a small agricultural drilling device in the prior art, and the irrigation device is configured as a sprinkler or watering device in the prior art. Those skilled in the art can select any suitable device or equipment from the prior art.

[0063] Finally, it should be noted that this utility model is not limited to the above-described optional embodiments, and anyone can derive other various forms of products under the guidance of this utility model. The above specific embodiments should not be construed as limiting the scope of protection of this utility model, which should be determined by the claims, and the description can be used to interpret the claims.
