Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a small-sized transplanting device for seedlings. Background Art

[0002] When transplanting seedlings, the traditional method is to dig out seedling nests in advance, and then transplant the seedlings one by one into the seedling nests, so that the seedlings can maintain an appropriate distance between each other, so that they can better absorb water and photosynthesize, thereby helping the seedlings to grow healthily. Since the transplanted amount of seedlings is usually large, there are mainly the following disadvantages when transplanting seedlings manually.

[0003] 1. Low efficiency and damage to seedlings: The traditional method requires taking out seedlings one by one from the seedling tray, manually using a small hoe to dig the soil at the bottom of the pine tobacco nest, planting the seedlings, and then manually backfilling the soil to cover. This process is labor-intensive, slow to transplant, and it is difficult to ensure uniform compaction of the backfill soil, which can easily damage the seedling roots or loosen the covering soil, affecting the survival rate.

[0004] 2. Existing transplanting equipment has a single function: There are transplanters on the market that can assist in seedling removal and planting, but they generally lack an integrated backfill control mechanism. For example, some devices only realize the function of hole opening or seedling planting, and still need to be manually completed to compact the soil, resulting in unstable backfill compaction and seedling fixation effect, and it is difficult to adapt to different soil moisture requirements.

[0005] 3. Poor watering control accuracy and serious waste of water resources: Traditionally, external water pipes are required for flooding after transplanting, which has two major defects: Insufficient water control ability: It is impossible to accurately adjust the irrigation amount according to the water demand of the seedlings, which is prone to drought or waterlogging problems; Low water resource utilization rate: Ineffective leakage 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: Although large-scale transplanting machinery can improve efficiency, its purchase and maintenance costs are high, and it has strict requirements on the size of the plot and the flatness of the terrain. Most of my country's flue-cured tobacco planting areas (such as Yunnan, Guizhou and Sichuan) are scattered small terraces or sloping land, which are difficult to apply to large-scale mechanized operations, resulting in a low penetration rate of existing technologies.

[0007] In summary, the existing technology is difficult to meet the needs of efficient, water-saving and low-damage transplanting in small-scale planting scenarios due to problems such as functional fragmentation, extensive water control and poor cost adaptability. Therefore, it is urgent to develop an integrated device that integrates seedling removal, backfilling and precise watering functions to reduce manual dependence and improve transplanting quality.

DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that although the description of these embodiments is used to help understand the present invention, it does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0034] According to a specific embodiment of the present invention, a small-sized transplanting device for seedlings is provided. Figures 1 to 5 One specific embodiment is shown.

[0035] See also Figures 1 to 5 As shown, the small-scale transplanting equipment for seedlings includes a drilling device 2 and an irrigation device 3 connected to a positioning member 1, and the small-scale transplanting equipment for seedlings also includes a seedling storage tube 41, which is fixedly connected to the positioning member 1, wherein a seedling outlet of the seedling storage tube 41 is provided with a pressure plate 42, and the pressure plate 42 is rotatably connected to the seedling storage tube 41 so as to be able to close and conduct the seedling outlet; the drilling device 2 is movably connected to the positioning member 1 through a sliding structure so as to be able to move in a vertical direction under the action of a force; the water inlet end of the irrigation device 3 is connected to a water source, and the water outlet end is arranged opposite to the seedling outlet, so as to be used for irrigating the seedlings in the base soil.

[0036] The support frame 8 is located below the positioning member 1 and is fixedly connected to the support frame 8, and the drill bit of the drilling device 2 is arranged in the annular cavity of the support frame 8. The support frame 8 provides a stable support platform for the drilling device 2, so that the drilling device 2 can maintain a stable state during operation. Since the support frame 8 is fixedly connected to the positioning member 1, the shaking and vibration of the drilling device 2 during the drilling process can be effectively reduced, thereby improving the accuracy and quality of the drilling. The drill bit is arranged in the annular cavity of the support frame 8, and the annular cavity can play a certain guiding and restraining role on the drill bit, so that the drill bit can move along a predetermined trajectory during the drilling process, further improving the accuracy and consistency of the drilling. This design helps to ensure that the position and depth of the drilling meet the requirements and provide accurate holes for transplanting seedlings.

[0037] In addition, the setting of the support frame 8 can relatively isolate the drilling device 2 from the external environment, reducing the interference and damage of the drilling device 2 by external factors during use. For example, during the movement or storage of the transplanter, the support frame 8 can prevent the drilling device 2 from colliding with other objects and protect the drill bit from damage. Based on the setting of the support frame 8, it can also protect the drilling device 2, reduce the wear and damage of the drilling device 2, and thus extend the service life of the drilling device 2. This not only reduces the maintenance cost of the equipment, but also improves the reliability and economy of the equipment.

[0038] The operator moves the transplanter to the preset planting point, and drives the drilling device 2 to move down along the sliding structure through external force, forming a planting hole in the base soil that matches the root size of the tobacco seedling. After the drilling is completed, the drilling device 2 is reset to the initial position. A single seedling is pre-stored in the seedling storage tube 41. When the planting hole is formed, the pressure plate 42 is operated to rotate around the seedling storage tube 41 to open the seedling outlet, and the seedling falls accurately into the planting hole under the action of gravity; then the pressure plate 42 rotates in the opposite direction to close the seedling outlet. The water outlet of the irrigation device 3 corresponds to the position of the seedling outlet. After the seedlings are planted, the water source injects water into the planting hole in a quantitative manner through the irrigation device 3, and the water flow directly acts on the root area of ​​the seedling, avoiding the waste of water diffusion caused by traditional flooding.

[0039] Through the above technical scheme, the actions of drilling, planting seedlings, covering soil, and watering are completed at one time through mechanical linkage, which reduces the manual operation links and significantly shortens the transplanting time of a single plant. The pressure plate 42 has the function of opening and closing the seedling outlet to ensure that the seedlings are upright and stable. The water outlet of the irrigation device 3 is directly aimed at the planting hole, and with the quantitative water supply design (such as a flow controller or pulse water injection), precise irrigation on demand is achieved to reduce the loss of ineffective water resources. In view of the characteristics of fast water seepage in slopes in Yunnan, Guizhou and Sichuan, directional irrigation can maintain the soil moisture around the roots and avoid surface runoff. Simple mechanical components such as sliding structures and pressure plates 42 are used, and there is no need for complex power systems, which reduces manufacturing costs and maintenance difficulties. The overall structure of the small transplanting equipment for seedlings is lightweight, adapts to terrain conditions such as terraces and slopes, and overcomes the dependence of large machinery on the scale and flatness of the plot.

[0040] Specifically, the positioning member 1 includes a positioning rod 11 and a light rod 12 arranged in parallel, and the upper and lower ends of the positioning rod 11 are connected to the light rod 12 through positioning plates. The positioning member 1 is composed of the positioning rod 11 and the light rod 12 arranged in parallel, and 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 tube 41 and the irrigation device 3 is relatively fixed.

[0041] The irrigation device 3 and the seedling storage tube 41 are both fixedly connected to the positioning rod 11; the sliding structure includes a base 61 and a sleeve 62, the sleeve 62 is sleeved on the light rod 12, and the drilling device 2 is fixedly connected to the sleeve 62 through the base 61. Before operation, the transplanter is moved as a whole to the planting point, and the positioning rod 11 serves as the bearing body. The seedling storage tube 41, the irrigation device 3 connected thereto, and the drilling device 2 in the sliding structure form an operating axis in the vertical direction to ensure the coordination of the movements of each component. The operator applies an external force to the drilling device 2, driving the base 61 to drive the sleeve 62 to slide along the light rod 12, so that the drilling device 2 moves downward in the vertical direction to form a planting hole with controllable depth in the base soil. The sliding fit between the light rod 12 and the shaft sleeve 62 provides a linear guide to avoid drilling deviation, ensure the verticality of the planting hole, and adapt to the growth requirements of the seedling root system; after the drilling is completed, the external force is removed, and the drilling device 2 slides up and resets along the light rod 12 under the action of gravity or a reset mechanism (such as a spring 53) to avoid obstruction of subsequent seedling planting.

[0042] The seedling storage tube 41 is fixed to the positioning rod 11, and its seedling outlet is directly opposite to the planting hole position, and a single seedling is built in; the seedling outlet is opened by rotating the pressure plate 42, and the seedling falls into the hole accurately, and then the pressure plate 42 rotates in the opposite direction to close the seedling outlet. The irrigation device 3 is fixed to the positioning rod 11, and its water outlet is aligned with the seedling outlet position. After the seedling is planted, the water flow is directly injected into the bottom of the planting hole, avoiding water diffusion and waste caused by traditional flood irrigation.

[0043] The positioning rod 11 and the light rod 12 form a double-track parallel frame through the positioning plate, which greatly improves the overall rigidity of the equipment, resists the lateral force during drilling, and avoids positioning deviation caused by the shaking of the device. The precise matching of the sleeve 62 and the light rod 12 in the sliding structure ensures the linear motion of the drilling device 2, avoids the common hole opening tilt problem in manual operation, ensures the verticality of the planting hole ≤3°, and meets the requirements of upright planting of seedlings. Directional irrigation reduces the water consumption of a single plant to 30%-40% of traditional flooding, especially in slope scenarios, and can reduce water loss caused by runoff by more than 50%.

[0044] Further, 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 connecting rod assembly 54 and a clamping 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 through a pin shaft, 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 connecting rod assembly 54 is fixedly connected to the pin shaft, and the other end is provided with a clamping plate, which is arranged opposite to the positioning plate located at the upper end of the positioning rod 11, and a clamping groove matching the positioning plate is provided on the clamping plate. When the movable handle 52 is pulled upward, the positioning assembly can be rotated with the pin shaft, and the clamping plate can be rotated and moved away from the positioning plate to release the locking of the positioning plate in the vertical direction; when the movable handle 52 is released, the movable handle 52 is reset under the action of the spring 53, and the clamping plate rotates and gradually approaches the positioning plate to be locked to the positioning plate.

[0045] When not in operation, the tension of the spring 53 makes the movable handle 52 close to the fixed handle 51, and the first connecting rod assembly 54 drives the slot on the card plate to form a vertical mechanical bite with the positioning plate at the upper end of the positioning rod 11, preventing the sleeve 62 from sliding along the light rod 12, ensuring that the drilling device 2 is at a fixed height. The operator pulls the movable handle 52 upward with one hand, and the movable handle 52 rotates around the pin and stretches the spring 53. At the same time, the first connecting rod assembly 54 drives the card plate to rotate, so that the slot is separated from the positioning plate, and the vertical lock of the sliding structure is released. At this time, the drilling device 2 can slide down along the light rod 12 under the action of external force.

[0046] When the operator presses down the drilling device 2, the sleeve 62 moves down along the polished rod 12, and the drilling head cuts into the soil to form a planting hole; when the preset depth (limited by the length of the polished rod 12 or the position of the positioning plate) is reached, the movable handle 52 is released, and the spring 53 rebounds to drive the movable handle 52 to reset, and the card plate rotates to re-engage the card 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 up the movable handle 52 again to unlock it, manually lifts the drilling device 2 to the initial height, and the card plate automatically locks after releasing the handle, preparing for the next transplant cycle.

[0047] Through the lever design of the movable handle 52 and the spring 53, the operator can complete the whole process of unlocking-pressing-resetting with one hand, reducing the coordination difficulty of traditional two-handed operation; the spring 53 assists in resetting and reduces the strength of manually lifting the drilling device 2, saving about 40% of physical effort compared with pure manual operation. The mechanical engagement of the card slot and the positioning plate forms a rigid stopper to ensure that the depth deviation of each drilling is ≤2cm (the depth deviation of traditional manual hole opening is generally >5cm), avoiding the seedlings from falling over due to shallow planting holes or growth lag due to too deep planting holes. The preload force of the spring 53 maintains the normal locking state to prevent the drilling device 2 from accidentally sliding down during non-operation periods, thereby improving safety. The control component 5 (fixed handle 51, movable handle 52, connecting rod) is integrated on the side of the base 61, without a complex convex mechanism, to avoid collision with surrounding crops or obstacles during field operations. The card slot and the positioning plate are made of hardened steel, and the contact surface can withstand ≥5000 locking-unlocking cycles, meeting the needs of high-intensity continuous operations. The spring 53, the pin shaft, and the connecting rod are all general mechanical parts, and the replacement cost is extremely low, which is suitable for rural users to repair by themselves. In addition, the structural setting of the small transplanting equipment for seedlings also avoids the risk of failure of electronic sensors or hydraulic systems, and is particularly suitable for the humid and rainy environment in Yunnan, Guizhou and Sichuan.

[0048] In one embodiment, a mounting shaft is provided on the seedling storage tube 41, and a torsion spring 44 is sleeved on the mounting shaft; an L-shaped mounting seat 45 is provided on the pressure plate 42, and the mounting seat 45 is provided with a lever 46; one end of the torsion spring 44 presses against the seedling storage tube 41, and the other end presses against the mounting seat 45; a positioning shaft is provided on the positioning rod 11 of the positioning member 1, and a rotatable dynamic pressure plate is provided on the positioning shaft, and the lever 46 is rotatably connected to the dynamic pressure plate; wherein, a support arm for pressing the dynamic pressure plate is provided on the base 61, and when the base 61 moves upward, the support arm can press the dynamic pressure plate, so that the pressure plate 42 is opened; when the pressure on the dynamic pressure plate disappears, the mounting seat 45 is reset under the action of the torsion spring 44, so that the pressure plate 42 is closed.

[0049] When the base 61 moves upward, the arm presses the dynamic pressure plate, and the dynamic pressure plate rotates, driving the pressure plate 42 to open through the lever 46, and the seedling outlet of the seedling storage tube 41 is connected. The seedlings are moved out of the seedling outlet under the action of gravity or other auxiliary forces and planted in the pre-drilled holes. When the pressure on the dynamic pressure plate disappears, the mounting seat 45 is reset under the action of the torsion spring 44, and the pressure plate 42 closes, closing the seedling outlet of the seedling storage tube 41, preparing for the next transplant.

[0050] The upward movement of the base 61 and the linkage mechanism of the dynamic pressure plate realize the automatic opening and closing of the pressure plate 42, further improving the automation of the transplanting process and reducing the complexity of manual operation. The opening and closing of the pressure plate 42 are precisely controlled by the linkage mechanism of the torsion spring 44 and the dynamic pressure plate, ensuring the stability and accuracy of the seedlings during the transplanting process and avoiding damage to the seedlings due to improper operation.

[0051] Specifically, a rotatable roller 48 is provided at the end of the pressing plate 42, and the roller 48 partially overlaps with the support arm in the horizontal direction, so that the support arm can press the roller 48 when moving. When the base 61 moves upward, the support arm presses the movable pressure plate, and the movable pressure plate rotates, driving the pressing plate 42 to open through the lever 46, and the seedling outlet of the seedling storage tube 41 is connected. The seedlings are moved out of the seedling outlet under gravity or other auxiliary effects and planted in the pre-drilled holes.

[0052] A rotatable roller 48 is provided at the end of the pressure plate 42, and the roller 48 partially overlaps with the support arm in the horizontal direction. When the support arm moves, it can press the roller 48, further ensuring that the opening action of the pressure plate 42 is smoother and more stable. When the pressure on the dynamic pressure plate disappears, the mounting seat 45 is reset under the action of the torsion spring 44, and the pressure plate 42 is closed, closing the seedling outlet of the seedling storage tube 41, preparing for the next transplanting.

[0053] In an embodiment provided in the present disclosure, a mounting groove for accommodating the end of the torsion spring 44 is provided on the mounting seat 45, which can effectively limit the position of the torsion spring 44 so that it can be better constrained, ensuring that the elastic force can be effectively transmitted, and further improving the stability and reliability of the transplanting process.

[0054] In an embodiment provided in the present disclosure, a drilling switch 71 is provided at the lower end of the fixed handle 51 , and 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 rotate.

[0055] The drilling switch 71 is arranged at the lower end of the fixed handle 51. When the operator holds the fixed handle 51 for operation, he can conveniently touch the drilling switch 71 with his other hand to start the drilling device 2, without the need for additional manual operation or complicated control devices, thereby improving the convenience and fluency of operation. The movable handle 52 can immediately start the drilling device 2 by touching the drilling switch 71, thereby reducing operation delays, enabling rapid response to drilling operations, and improving work efficiency.

[0056] By starting the drilling device 2 by touching the drilling switch 71 with the movable handle 52, it can be ensured that the drilling operation is carried out at a precise position and timing. The operator can accurately control the start and end of drilling according to actual needs, avoiding unnecessary drilling or drilling position deviation. The linkage design of the drilling switch 71 and the movable handle 52 ensures that the drilling device 2 will only be started 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 the safety and reliability of operation.

[0057] The operator can start the drilling device 2 at any time by touching the drilling switch 71 during the process of moving the transplanter, thereby realizing continuous drilling operation without frequently manually opening and closing the drilling device 2, thereby improving the efficiency of the entire transplanting process. The drilling switch 71 is combined with the movable handle 52 to simplify the operation process, reduce the number of operation steps that the operator needs to perform, and make the entire transplanting process more efficient.

[0058] In the present 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 at the upper end of the light rod 12, and 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 touches the water outlet switch 72. This touch action triggers the irrigation device 3 to start working, thereby realizing precise irrigation of the seedlings. This automated control method can ensure that water is provided to the seedlings in time during the critical period after transplanting, which is conducive to the survival and growth of the seedlings.

[0059] Through the cooperation of the touch arm 63 and the water outlet switch 72, the irrigation device 3 is activated only when irrigation is needed, thereby avoiding the waste of water resources in the traditional watering method. When watering is not needed, the water outlet switch 72 is in a closed state, and water will not flow away, thereby improving the utilization efficiency of water resources.

[0060] In this way, the setting based on the touch arm and the water outlet switch 72 enables the three steps of drilling, transplanting and irrigation to work more closely together. During the transplanting process, after the seedlings are planted in the base soil, the touch arm triggers the water outlet switch 72 for irrigation. The whole process is completed in one go, which greatly improves the transplanting efficiency. The water outlet switch 72 is connected to the irrigation device 3 to ensure the uniformity of irrigation. Compared with the traditional manual watering method, this automated irrigation method can more evenly transport water to the roots of the seedlings, avoid the problem of inconsistent seedling growth caused by uneven watering, and improve the quality of transplanting.

[0064] In one embodiment, the guide tube has an inclination angle α relative to the vertical direction, and α is 20° to 50°.

[0065] The inclined setting of the guide cylinder can provide a smooth path for the seedlings to move out. When the pressure plate is opened and the seedlings are moved out of the seedling outlet of the seedling storage cylinder, the guide cylinder can guide the seedlings to smoothly enter the pre-drilled holes along its inclined direction to prevent the seedlings from getting stuck or offset during the removal process, ensuring that the seedlings can be accurately implanted in the base soil. By adjusting the inclination angle and length of the guide cylinder, it can adapt to transplanting needs at different depths. In this way, even under different soil conditions and planting requirements, the transplanting depth of the seedlings can be flexibly adjusted to ensure that the seedlings grow at an appropriate depth, which is conducive to improving the survival rate and growth quality of the seedlings.

[0066] The inclined setting structure of the guide cylinder can stabilize the posture of the seedlings during transplanting, avoiding the decline of transplanting quality caused by shaking or tilting of the seedlings. Under the guidance of the guide cylinder, the seedlings can be planted in the base soil in the correct posture, which is conducive to the full contact between the roots of the seedlings and the soil, promotes the growth and development of the seedlings, and improves the quality of transplanting.

[0067] The guide cylinder is fixedly connected to the positioning piece and is closely connected to the structure of the entire transplanter, which enhances the overall stability of the equipment. During the transplanting process, the guide cylinder can maintain a stable position and posture, and will not loosen or shift due to external forces, ensuring the reliability and consistency of the transplanting operation.

[0068] In an embodiment provided by the present disclosure, the pressure plate is located on the inner side close to the positioning member, and the seedling outlet is located in the middle area of ​​the guide cylinder, which is conducive to accurately controlling the release timing of the seedlings. When the pressure plate is opened, the seedlings are moved out of the seedling outlet under the influence of gravity or other auxiliary effects. Since the pressure plate is located close to the positioning member, it can be ensured that the seedlings will not be offset or stuck during the removal process, and the seedlings can be ensured to enter the guide cylinder smoothly.

[0069] The seedling outlet is located in the middle area of ​​the guide cylinder, so that the seedlings can directly enter the center of the guide cylinder when they are moved out. The tilt setting of the guide cylinder can provide a smooth transplanting path for the seedlings, ensuring that the seedlings can be accurately implanted in the base soil, and avoiding the seedlings from shifting or lodging during the transplanting process. By adjusting the tilt angle and length of the guide cylinder, it can meet the transplanting needs of different depths. The seedling outlet is located in the middle area of ​​the guide cylinder, so that the seedlings can better adapt to the tilt angle of the guide cylinder when they are moved out, ensuring that the seedlings can smoothly enter the base soil when transplanting at different depths.

[0070] In an embodiment provided by the present disclosure, the support frame 8 is annular or arc-shaped, and the support frame 8 is fixedly connected to the fixing member through a column. The annular or arc-shaped support frame 8 has good rigidity and anti-deformation ability, can provide more stable support for the drilling device 2, effectively reduce the shaking and vibration of the drilling device 2 during operation, thereby improving the accuracy and quality of drilling.

[0071] The support frame is fixedly connected to the fixing part through the column, and the column can accurately adjust the height and position of the support frame 8 to ensure that the drilling device 2 can maintain an accurate position and angle during the drilling process. Precise positioning helps to improve the consistency and accuracy of drilling, reduce problems such as poor seedling growth or uneven planting density caused by inaccurate transplanting position, and improve the overall quality of transplanting.

[0072] The annular or arc-shaped support frame 8 can relatively isolate the drilling device 2 from the external environment, reducing interference and damage to the drilling device 2 from external factors during use. For example, during the movement or storage of the transplanter, the support frame 8 can prevent the drilling device 2 from colliding with other objects and protect the drill bit from damage.

[0073] In the present disclosure, the drilling device 2 includes a motor 21, a transmission shaft 22 and a blade 24, wherein one end of the transmission shaft 22 is transmission-connected to the output shaft of the motor 21, and the other end is provided with a barrel 23, and a spiral blade 24 is provided on the barrel 23. In this way, the rotation center of the transmission shaft 22 is parallel to the Z direction. When the motor 21 rotates, it can transmit power to the barrel 23, thereby driving the blade 24 to rotate, and then drilling a hole in the base soil.

[0074] Among them, the spiral blade 24 is designed with good soil cutting performance and can effectively cut and crush the soil during the drilling process. As the blade 24 rotates, the soil is continuously cut and transported upward to form neat holes, which improves the efficiency and quality of drilling. During the rotation process, the blade 24 can also loosen and stir the soil to a certain extent, which is beneficial to improve the air permeability and drainage of the soil and create a good environment for the root growth of the seedlings. At the same time, the rotation of the spiral blade 24 can mix the surface soil with the bottom soil, making the nutrient distribution of the soil more uniform, which is beneficial for the seedlings to better absorb nutrients after transplanting and promote growth.

[0075] In one embodiment provided by the present disclosure, the irrigation device 3 includes a water storage cylinder 31, a water inlet pipe 32 and a water outlet pipe 33. The two ends of the water storage cylinder 31 are respectively connected to the water inlet pipe 32 and the water outlet pipe 33. The water inlet pipe is connected to the water source, and the water outlet pipe is arranged opposite to the guide cylinder. Among them, a solenoid valve 9 is provided on the water outlet pipe to control the on and off of the water flow in the pipeline, so as to supply and cut off water in time and reduce the waste of water resources. In this way, when the water source is insufficient, the water stored in the water storage cylinder can be used for supplementary irrigation.

[0076] The water storage tank is equipped with a float and a vent. Through the design of the float and the vent, the time and amount of watering can be controlled more accurately, reducing the waste of resources and poor crop growth caused by over-watering or under-watering. This can not only reduce the need for manual intervention and improve work efficiency, but is especially suitable for large-scale planting scenarios. In addition, the uniform and appropriate water supply helps protect the newly transplanted flue-cured tobacco seedlings and promote their healthy and rapid growth.

[0077] In the present disclosure, the irrigation device includes a water pump. The water outlet switch controls the working state of the water pump. Therefore, when it is necessary to irrigate the seedlings, the solenoid valve and the water outlet switch need to be started at the same time, so that the irrigation device irrigates the seedlings.
