Description

Technical Field

[0001] This invention relates to the field of peony cultivation technology, and in particular to an automatic peony transplanting device. Background Technology

[0002] In current industrialized peony cultivation practices, transplanting operations still largely rely on manual or semi-mechanized methods, resulting in significant problems such as high labor intensity, low efficiency, and insufficient standardization. Although agricultural automation technology has made significant progress in recent years in crops such as vegetables and tobacco, existing transplanting equipment generally suffers from poor adaptability, functional fragmentation, and insufficient operational precision when used for perennial woody flowers like peonies, which have fleshy root systems, large root balls, and stringent requirements for planting depth and soil covering quality.

[0003] Common general-purpose transplanters on the market usually separate the processes of turning the soil, fertilizing, transplanting, and covering the soil into independent procedures, lacking organic integration. In particular, it is difficult to realize the scientific cultivation logic of "fertilizing first and then covering the soil" - fertilizer is often directly exposed on the ground surface, which is easy to volatilize and lose or be washed away by rainwater, which not only reduces the fertilizer effect, but may also cause local seedling burn.

[0004] Meanwhile, the existing seedling supply system is unable to meet the special transportation needs of peony seedlings. There is a lack of precise coordination between the seedling supply rhythm and the transplanting action, which often results in problems such as missing seedlings, overlapping, or interruption of seedling supply, which seriously restricts the ability to operate continuously.

[0005] In summary, the current technology system has obvious shortcomings in terms of structural integration, operational adaptability, and process closed-loop. There is an urgent need for a highly efficient automatic transplanting device specifically designed for peonies that integrates soil turning, fertilization, seedling supply, transplanting, and soil covering to break through the technical bottleneck of improving the quality and efficiency of the industry.

[0017] By employing the technical solution described above, the present invention has the following beneficial effects: (1) The present invention adopts a detachable design, which allows the frame to be easily connected to the tractor and the height to be adjusted according to the operation requirements, thereby adapting to the operation requirements of different plots. The four-wheel support structure design ensures that the device can still be parked independently or moved a short distance after being detached from the tractor, which is convenient for transportation, maintenance or adjustment of the operation position.

[0018] (2) The integrated design of the soil turning and fertilizing mechanism of this invention realizes the scientific cultivation logic of "fertilizing first and then covering with soil". The crushing device breaks larger soil clods into small particles and covers them on the spread fertilizer, preventing the fertilizer from being exposed to the ground and causing volatilization loss or being washed away by rainwater. At the same time, the soil covering layer helps to maintain soil moisture and promotes the slow release of fertilizer, which greatly improves the survival rate and early growth vigor of peony after transplanting. The conveying device adopts a chain plate structure and a conveyor belt with partitions, which not only improves the conveying efficiency and the reliability of system operation, but also effectively avoids the problem of soil clods accumulating and blocking in the rotary tillage area, ensuring the continuous operation capability of the whole machine.

[0019] (3) The multi-channel synchronous seedling supply layout of the seedling supply mechanism of the present invention significantly improves the number of seedlings supplied per unit time and the overall operation efficiency. The S-shaped vertical stacking structure of the guide rail extends the seedling transport path within a limited space, meeting the demand for seedling supply in continuous operation, while the flexible clamping method reduces mechanical damage to the seedling stems. This design ensures that each seedling maintains an independent and neat posture when it reaches the seedling outlet, providing a foundation for subsequent precise grasping.

[0020] (4) The combined use of the planting mechanism and the transplanting mechanism of this invention realizes fully automated operation from seedling supply to transplanting, reducing manual intervention and improving transplanting consistency. In particular, the ingenious design of the swing arm drive device and the telescopic arm ensures that each transplant can be accurately reset above the target planting point, greatly improving the accuracy of operation repetition. The structural design of the opening and closing claws ensures the safety of seedlings during transportation and improves the transplanting success rate. The entire process is efficient and continuous, and is particularly suitable for long-term continuous operation. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Example 1:

[0026] Combined with appendix Figures 1-3 An automatic peony transplanting device includes a frame 1, a soil-tilling and fertilizing mechanism, a seedling supply mechanism 6, a planting mechanism, and a transplanting mechanism 14. The frame 1 serves as the mounting carrier for the entire device, with its head end connected to the tail end of a tractor. Specifically, the frame 1 is detachably mounted on the towing frame at the tail end of the tractor. This design allows the operator to adjust the height of the frame 1 according to operational needs, thereby adjusting the rotary tillage depth and fertilization covering height to ensure adaptability to different plots of land. This structure ensures the stability of the entire machine during field operations, avoiding problems such as uneven fertilization or damage to the underground root system due to undulating terrain.

[0027] To ensure that the entire device can be parked or moved short distances independently after being detached from the tractor, a wheel is fitted at each of the four corners of the frame 1. These wheels are fixed to the wheel frame at the bottom of the frame 1 via axles, supporting not only the weight of the entire machine but also providing rolling support when moving in the field. The four-wheel support structure allows the device to be parked or pushed independently after being detached from the tractor, facilitating transportation, maintenance, or adjustment of the working position.

[0028] A soil-turning and fertilizing mechanism is installed at the head end of the frame 1. This mechanism is used to level the land, loosen the soil, and apply fertilizer. Specifically, the soil-turning and fertilizing mechanism consists of a rotary tiller 2, a fertilizing device 3, a crushing device 4, and a conveying device 5. The rotary tiller 2 is installed at the head end of the frame 1, using a commercially available device and connected to the tractor's PTO output shaft via a universal drive shaft. The tractor's power take-off shaft provides rotational power, driving the rotary tiller blades to turn and break up the soil. This connection method ensures smooth and reliable power transmission and facilitates quick attachment and disassembly, improving work efficiency. The soil after rotary tilling becomes loose and level, creating favorable conditions for subsequent fertilization, covering, and transplanting of peony seedlings.

[0029] Furthermore, a fertilizer application device 3 is installed at the bottom of the frame 1, located behind the rotary tiller 2. This device 3 is used to spread fertilizer. The fertilizer is evenly spread on the surface of the tilled soil by the fertilizer application device 3, preventing excessive local concentration from burning the seedlings or uneven distribution from affecting peony growth. A crushing device 4 is installed above the fertilizer application device 3 on the frame 1, and a conveying device 5 is installed between the rotary tiller 2 and the crushing device 4. The conveying device 5 transports larger clods of soil and some soil generated after rotary tillage from the front end of the work area to the crushing device 4 at the rear end. The crushing device 4 further breaks the larger clods of soil into fine particles, and the falling soil covers the spread fertilizer, forming a "fertilize first, then cover with soil" operation process. This structure effectively prevents fertilizer from being exposed to the surface and thus losing it through volatilization or being washed away by rainwater. At the same time, the soil cover helps maintain soil moisture and promotes the slow release of fertilizer, thereby improving the survival rate and early growth vigor of peonies after transplanting.

[0030] Specifically, as shown in the attached document Figure 4 As shown, the conveying device 5 includes a feeding roller 5-1, feeding rods 5-2, and a conveyor belt 5-3. The feeding roller 5-1 is rotatably connected to the frame 1 via bearing seats at both ends. A first motor for driving the feeding roller 5-1 is mounted on the frame 1. Multiple feeding rods 5-2 are arranged in a circumferential and axial array on the surface of the feeding roller 5-1. The conveyor belt 5-3 is obliquely installed between the feeding roller 5-1 and the crushing device 4. When the first motor starts, the feeding roller 5-1 drives the feeding rods 5-2 to rotate, feeding larger clods of soil and some broken soil accumulated at the front of the frame 1 after rotary tillage onto the conveyor belt 5-3. The conveyor belt 5-3 then transports these larger clods of soil and broken soil upwards to the feed inlet of the crushing device 4. This structure effectively prevents soil from accumulating and clogging in the rotary tillage area, ensuring the continuous operation capability of the entire machine.

[0031] It should be noted that the conveyor belt 5-3 adopts a chain plate structure, and its belt surface is equipped with multiple baffles perpendicular to the running direction at intervals along the running direction. These baffles can support larger clods and loose soil during the operation of the conveyor belt 5-3, allowing them to rise stably along the inclined path, preventing the material from slipping back to its original position due to gravity during the conveying process, thereby improving the conveying efficiency and the reliability of the system operation.

[0032] A soil testing device 7 is also installed on one side of the conveyor device 5. This device is used to perform real-time testing on the soil transported by the conveyor belt 5-3 after tilling, in order to obtain the soil's physicochemical parameters and provide data support for subsequent peony transplanting operations. (See attached image) Figure 1 As shown, the soil testing device 7 can be configured as two sets, located on both sides of the conveyor belt 5-3 respectively. (See attached diagram) Figure 8 As shown, each soil testing device 7 includes a soil tester 7-1, a rotating sleeve 7-2, and a feed tube 7-3. The soil tester 7-1 is a commercially available model QT-WS-01, which has wireless communication capabilities and can transmit test results in real time to an external control terminal or a display device on the tractor, allowing operators to promptly grasp the soil condition of the current work area.

[0033] The soil testing instrument 7-1 is horizontally fixed to the frame 1, with its testing end facing the conveyor belt 5-3. A rotating sleeve 7-2 is rotatably connected to the outside of the testing end. The axis of the rotating sleeve 7-2 is coaxial with the testing end of the soil testing instrument 7-1, ensuring that the testing end is always within the internal channel of the rotating sleeve 7-2 and is not affected by external interference. Multiple guide tubes 7-3 are evenly spaced along the circumference of the rotating sleeve 7-2. One end of each guide tube 7-3 is connected to the rotating sleeve 7-2, and the other end extends above the conveyor belt 5-3, forming a periodic meshing relationship with the partitions on the conveyor belt 5-3. When the conveyor belt 5-3 is running, the partitions on it sequentially push the free ends of each guide tube 7-3, subjecting the guide tubes 7-3 to periodic thrust, which in turn drives the rotating sleeve 7-2 to rotate continuously around its axis.

[0034] During rotation, the end of the feed pipe 7-3 near the conveyor belt 5-3 contacts and intercepts a portion of the broken soil being transported on the conveyor belt 5-3, guiding this portion of broken soil into the inner cavity of the rotating sleeve 7-2. This ensures that the broken soil makes full contact with the detection end of the soil analyzer 7-1, completing one soil sampling and testing process. As the rotating sleeve 7-2 continues to rotate, the tested broken soil, under the combined action of gravity and centrifugal force, is discharged from the open end of the rotating sleeve 7-2 away from the soil analyzer 7-1, thus achieving a continuous and automatic soil sampling and testing cycle. This soil sampling and testing mechanism provides a relatively reliable data foundation for variable fertilization operations, helping to improve the scientific nature of fertilization.

[0035] A seedling supply mechanism 6 is installed at the rear end of the frame 1. The seedling supply mechanism 6 includes a box 6-1 and a seedling storage mechanism. The box 6-1 serves as the main support structure of the seedling storage mechanism, used to support and accommodate all components of the entire seedling storage mechanism, while providing necessary external protection for the internal components. (See attached image) Figure 12 and 13 As shown, multiple seedling storage mechanisms are arranged at intervals along the horizontal direction inside the box 6-1, forming a multi-channel synchronous seedling supply layout, which significantly improves the number of seedlings supplied per unit time and the overall operating efficiency. A seedling outlet is provided on one side of the box 6-1 corresponding to the output end of each seedling storage mechanism. The position of this outlet is strictly aligned with the end of the seedling storage mechanism, ensuring that the peony seedlings can smoothly and unobstructedly enter the seedling picking position of the transplanting equipment after being transported to the end, effectively avoiding seedling jamming caused by positional deviation or mechanical damage to the seedling roots.

[0036] Specifically, as shown in the attached document Figure 14 As shown, the seedling storage mechanism includes a guide rail 6-2, clamping belts 6-3, and a reel 6-4. The guide rail 6-2 is fixedly installed inside the housing 6-1, and has an overall S-shaped vertical stacking structure. This structure can significantly extend the seedling transport path within a limited vertical space, thereby increasing the single-load capacity without increasing the overall height of the equipment, meeting the demand for seedling supply in continuous operations. The guide rail 6-2 has guide grooves arranged vertically and horizontally, and the two clamping belts 6-3 slide and engage in the upper and lower guide grooves respectively. The cross-sectional shape of the guide grooves is dovetail-shaped or T-shaped. This type of structure has good limiting performance and can effectively prevent the clamping belts 6-3 from laterally dislodging, shifting, or overturning during operation, ensuring the stability of the transport process. The peony seedlings are horizontally clamped between the two clamping belts 6-3; the clamping effect is achieved by the moderate pressure generated by the flexible material of the clamping belts 6-3 and their tension, forming a wrapping clamp on the seedling stem, avoiding epidermal damage or tissue crushing that may occur with rigid clamping methods.

[0037] To effectively isolate adjacent seedlings, multiple protruding strips extending from the guide groove surface are spaced along the length of the inner sides of the two clamping belts 6-3. These protruding strips on the upper and lower clamping belts 6-3 correspond one-to-one in relative position and abut against each other, forming an independent clamping unit. Each unit accommodates one peony seedling. This structure prevents seedlings from becoming disordered or physically damaged during transport due to squeezing, collision, or entanglement of branches and leaves, ensuring that each seedling maintains an independent and neat posture upon reaching the seedling outlet, providing a structural basis for the precise grasping of the subsequent transplanting mechanism 14. Two rollers 6-4 are installed inside the housing 6-1 near the seedling outlet. The rollers 6-4 are rotatably connected to the housing 6-1 via bearings or bushings. The ends of the two clamping belts 6-3 are respectively wound around the two rollers 6-4. A fourth motor is also installed inside the housing 6-1, which is connected to the two rollers 6-4 for synchronously driving their rotation. The roller 6-4 orderly winds up the clamping belt 6-3, pushing the peony seedlings clamped between them to move forward one by one along the guide rail 6-2, achieving a continuous and stable seedling supply action, avoiding seedling leakage, overlap, or disordered seedling supply rhythm caused by intermittent or skipped pushing.

[0038] A planting mechanism is installed in the area of ​​the frame 1 between the soil-turning and fertilizing mechanism and the seedling supply mechanism 6. Multiple planting mechanisms are spaced apart along the transverse direction of the frame 1. (See attached diagram) Figure 10 As shown, each planting mechanism includes a swing arm 8, a telescopic arm 10, and an opening / closing claw 11, as well as a swing arm drive device 9 for driving the swing arm 8 to swing in coordination with the frame 1 as it moves, and an opening / closing claw drive device 12 for driving the opening and closing of the opening / closing claw 11. The top of the swing arm 8 is hinged to the frame 1 via a pin, allowing it to swing in a vertical plane; the swing arm drive device 9 is mounted on the frame 1, and its drive end is connected to the middle or lower part of the swing arm 8. During peony transplanting, the swing arm drive device 9 drives the swing arm 8 to swing in the direction the frame 1 is moving. As the frame 1 moves forward, the swing arm 8 gradually swings back in the opposite direction under the drive, thereby ensuring that the opening / closing claw 11 carried at the end of the swing arm 8 can accurately align with the preset planting point during the transplanting of the same peony seedling, avoiding misalignment of the planting position due to travel deviation and improving transplanting accuracy.

[0039] A telescopic arm 10 is installed on the swing arm 8. The telescopic arm 10 is slidably set in the vertical direction. A pointed cone-shaped opening and closing claw 11 is installed at its bottom. This structure facilitates insertion into the soil and reduces resistance. An opening and closing claw drive device 12 is also installed on the telescopic arm 10. Its drive end is connected to the opening and closing claw 11 to control the opening and closing action of the opening and closing claw 11.

[0040] A seedling transplanting mechanism 14 is installed on the frame 1, in the area between the seedling supply mechanism 6 and the planting mechanism. Multiple seedling transplanting mechanisms 14 are spaced laterally along the frame 1, and each seedling transplanting mechanism 14 corresponds one-to-one with a planting mechanism. Specifically, as shown in the attached diagram... Figure 15 As shown, the transplanting mechanism 14 includes a fixed base 14-1, a rocker arm 14-2, a motor 14-3, a crank 14-4, and a pull rod 14-5. The fixed base 14-1 is mounted on the frame 1; one end of the rocker arm 14-2 is the drive end, and the other end has a fork-shaped structure for receiving peony seedlings from the seedling supply mechanism 6; the rocker arm 14-2 is hinged to the fixed base 14-1 near the drive end, allowing it to swing around the hinge point; the motor 14-3 is mounted on one side of the fixed base 14-1, and the output end of the motor 14-3 is connected to the crank 14-4; one end of the pull rod 14-5 is hinged to the crank 14-4, and the other end is hinged to the drive end of the rocker arm 14-2. (See attached diagram) Figure 16 and 17 As shown, when the motor 14-3 is running, the crank 14-4 drives the pull rod 14-5 to reciprocate, which in turn drives the rocker arm 14-2 to swing around the fixed base 14-1, realizing the grasping, transfer and release of peony seedlings. This four-bar linkage has a compact structure and a rapid response, and can be precisely synchronized with the seedling supply rhythm and planting action, ensuring that the seedling transfer process is efficient and stable, and avoiding seedlings falling or shifting in posture.

[0041] When transplanting peony seedlings, firstly, the frame 1 is connected to the tractor so that it moves with the tractor. The soil is loosened and fertilized by the soil-tilling and fertilizing mechanism. Then, the planting mechanism is controlled so that the opening and closing claw 11 is in the closed state. The seedling supply mechanism 6 supplies peony seedlings with soil balls one by one, and the transplanting mechanism 14 accurately transfers the seedlings into the cavity inside the opening and closing claw 11. Next, the swing arm drive device 9 is controlled to drive the swing arm 8 to swing in the direction of the frame 1. At this time, some of the fine soil crushed by the crushing device 4 can fall into the opening and closing claw 11, preparing for subsequent soil covering. Then, the telescopic arm 10 is controlled to move downward, causing the closed opening and closing claw 11 to penetrate into the soil to a predetermined depth. Then, the opening and closing claw 11 is controlled to open, releasing the peony seedling and its root ball. Immediately afterward, the telescopic arm 10 is controlled to retract upward. After the opening and closing claw 11 is removed from the soil, the loose soil inside and around the seedling naturally falls back, covering the roots of the peony seedling, completing the automatic soil covering process. This process requires no additional soil covering mechanism, effectively reducing manual intervention and improving transplant consistency. After the opening and closing claw 11 moves to its upper limit position, it is controlled to close again and tilted backward to prepare for the transplanting of the next peony seedling. The entire process is continuous and efficient, suitable for long-term continuous operation. Example 2:

[0042] Combined with appendix Figure 1 , 45. An automatic peony transplanting device, an improvement upon Embodiment 1. The feeding roller 5-1 has a hollow structure, and the feeding rod 5-2 is detachably connected to the feeding roller 5-1 via a threaded connection or pin. This design facilitates the replacement of feeding rods 5-2 of different lengths or shapes according to soil hardness or clod size, and also allows for individual replacement of feeding rods 5-2 after wear or breakage, reducing maintenance costs and extending the overall service life of the machine.

[0043] As attached Figure 5 As shown, the crushing device 4 includes a crushing chamber 4-1 and a crushing shaft 4-2. The crushing chamber 4-1 is fastened to the frame 1 with bolts to ensure structural stability under vibration conditions. The top of the crushing chamber 4-1 has a feed inlet for receiving soil clods conveyed by the conveyor belt 5-3; the bottom has a discharge outlet for discharging the crushed soil. This through-type structure allows for smooth material flow and reduces the risk of blockage. The crushing shaft 4-2 is rotatably connected to the inside of the crushing chamber 4-1 via a bearing assembly, and multiple sets of radially distributed crushing blades are mounted on its shaft along the axial direction; a second motor for driving the crushing shaft 4-2 is installed on the frame 1. During operation, the crushing blades rotate at high speed, impacting and shearing the soil clods entering the crushing chamber 4-1, crushing them into fine soil with a smaller particle size, meeting the requirements for fine soil compaction in peony planting.

[0044] It should be noted that the crushing device 4 and the conveying device 5 can share the same power source. For example, the power of the first motor driving the feeding roller 5-1 can be diverted to the crushing shaft 4-2 through a gearbox, chain drive, or pulley system, thereby reducing the number of motors, simplifying the electrical control system, reducing the overall manufacturing cost and energy consumption, reducing potential failure points, and improving the overall reliability of the system. Example 3:

[0045] Combined with appendix Figure 1 , 6 7. An automatic peony transplanting device, further optimizing the fertilization and soil covering structure based on Embodiment 1 or 2. The fertilization device 3 includes a fertilization chamber 3-1, a mesh plate 3-2, and a fertilizer bin 3-3. The fertilization chamber 3-1 is inclined, with both ends securely connected to the frame 1 via supports; an opening is provided on the lower side of the fertilization chamber 3-1; and multiple guide plates are provided on the upper side facing away from the opening. These guide plates are used to divert some of the soil discharged from the pulverizing device 4 towards the planting mechanism, providing covering soil for the transplanted peony seedlings.

[0046] A V-shaped perforated plate 3-2 is installed at the opening of the fertilizer bin 3-1, with the V-shaped tip pointing downwards and through holes evenly distributed on both sides of the inclined surface. Under the action of gravity, the fertilizer slides down the bottom surface of the fertilizer bin 3-1 onto the V-shaped perforated plate 3-2, and falls evenly through the mesh holes, avoiding the accumulation of fertilizer and achieving uniform fertilization in the lateral width direction.

[0047] Meanwhile, the top plane of the fertilizer bin 3-1 also serves as the discharge guide plate of the crushing device 4. After the crushed soil falls from the discharge port of the crushing device 4, it first contacts the top surface of the fertilizer bin 3-1 and slides down its inclined surface to the rear, naturally covering the spread fertilizer and forming a uniform layer of soil. No additional soil covering mechanism is required, which simplifies the overall structure of the machine.

[0048] A fertilizer bin 3-3 is installed on the top of the frame 1, used to store granular or powdered fertilizer. The bottom ends of the fertilizer bin 3-3 are connected to connecting pipes 3-4, which in turn connect to the two ends of the fertilizer application bin 3-1, forming a dual-channel feeding structure to ensure balanced fertilizer supply to all horizontal areas of the fertilizer application bin 3-1. A rotary feeder 3-5 is installed on each of the two connecting pipes 3-4. This rotary feeder 3-5 is a commercially available device with an internal rotor equipped with blades. Its rotation controls the flow of fertilizer from the fertilizer bin 3-3 into the fertilizer application bin 3-1 along the connecting pipes 3-4, allowing for controlled adjustment of the fertilizer application rate to meet the fertilizer requirements of different peony varieties or growth stages. The rotary feeder 3-5 is driven by a third motor, facilitating variable-rate fertilization based on soil parameters fed back by the soil testing device 7, thus improving the scientific nature of fertilization and resource utilization efficiency.

[0049] In addition, as attached Figure 9 As shown, a leveling roller 3-6 is rotatably connected to the frame 1 below the corresponding fertilizer bin 3-1. The leveling roller 3-6 rolls synchronously with the frame 1 to level the soil surface after covering, avoiding local accumulation of soil after being crushed by the crushing device 4, ensuring a uniform thickness of the covering layer, and facilitating good contact between the seedling roots and the soil. Example 4:

[0050] Combined with appendix Figure 12 and 14An automatic peony transplanting device is proposed, which optimizes the structure of the seedling supply mechanism 6 based on Embodiment 1. A straightening and guiding device 6-5 is added to the box 6-1 in the area between the two rollers 6-4. The straightening and guiding device 6-5 includes two spaced-apart arc-shaped guide rods, which are arranged at an angle. The higher end of the guide rod is vertically offset, while the lower end is on the same horizontal plane. When a peony seedling, held between two clamping belts 6-3, enters the straightening and guiding device 6-5 from the vertically offset end, it automatically slides down the curved surfaces of the two arc-shaped guide rods under the action of gravity. During this process, the seedling's posture gradually transitions from an initial horizontal state to a vertical state, ultimately resulting in roots facing downwards and stems and leaves facing upwards, conforming to the natural growth direction of the plant. This posture adjustment requires no additional power drive and is completed entirely by gravity and the geometric guidance of the guide rod surfaces, resulting in a simple structure and reliable operation. After being straightened, the seedlings can be directly inserted into the soil at the transplanting station, eliminating the need for manual or mechanical adjustment of the direction. This not only improves the efficiency of transplanting operations but also helps to increase the survival rate of seedlings.

[0051] To further control the seedling supply rhythm, a dial wheel 6-6 is rotatably connected above the straightening guide device 6-5 in the housing 6-1. Multiple slots are evenly distributed along the circumference of the dial wheel 6-6, with the spacing between the slots matching the spacing between adjacent peony seedlings on the clamping belt 6-3. A dedicated drive motor is installed inside the housing 6-1 to drive the dial wheel 6-6 to rotate intermittently. During the rotation of the dial wheel 6-6, its slots sequentially align with the seedlings entering the straightening guide device 6-5 and push them in, ensuring that only one seedling is fed into the straightening guide device 6-5 at a time. This effectively prevents multiple seedlings from entering simultaneously, causing blockages, posture confusion, or straightening failure, thus achieving precise synchronization and matching between the seedling supply action and the straightening process.

[0052] Furthermore, the housing 6-1 is equipped with an openable and closable door 6-7 on one side corresponding to its seedling outlet. The door 6-7 is connected to the housing 6-1 via a hinge or sliding rail structure and supports manual or electric opening. The door 6-7 facilitates the replenishment of peony seedlings into the seedling storage mechanism during equipment downtime, which is particularly suitable for mid-term seedling replenishment needs in long-term continuous operation scenarios. At the same time, opening the door 6-7 also provides a convenient passage for cleaning, replacing, or repairing key internal components such as the guide rail 6-2 and the clamping belt 6-3, significantly improving the maintainability and long-term operational reliability of the equipment.

[0053] In addition, the top of the box 6-1 is designed as an open structure, which allows operators to directly observe the remaining quantity and conveying status of peony seedlings inside the box 6-1 without opening the door 6-7, so as to promptly determine whether seedlings need to be replenished or abnormalities need to be investigated, effectively reducing unplanned downtime and ensuring the continuity and efficiency of seedling supply operations. Example 5:

[0054] Combined with appendix Figure 10 and 11 A planting device for peony transplanting is disclosed, which further refines the drive structure of the planting mechanism based on Embodiment 1. The swing arm drive device 9 includes a turntable 9-1 and a connecting rod 9-2. The turntable 9-1 is rotatably connected to the frame 1 via bearings, and a first motor for driving the rotation of the turntable 9-1 is installed on the frame 1; one end of the connecting rod 9-2 is hinged to the swing arm 8, and the other end is hinged to the eccentric position of the turntable 9-1. When the first motor drives the turntable 9-1 to rotate at a constant speed, the rotational motion is converted into the reciprocating swing of the swing arm 8 through the eccentric connecting rod mechanism. The motion trajectory is stable and controllable, ensuring that the swing arm 8 can accurately return to above the target planting point each time transplanting, thus improving the repeatability accuracy of the operation.

[0055] The telescopic arm 10 includes a movable rod 10-1 and a drive gear 10-2. The movable rod 10-1 slides with the swing arm 8 via a guide groove or guide rail to ensure the stability of its vertical movement; the top of the movable rod 10-1 is provided with a strip tooth; the drive gear 10-2 is rotatably connected to the swing arm 8 via a shaft, and a second motor connected to the drive gear 10-2 is mounted on the swing arm 8; the drive gear 10-2 meshes with the strip tooth at the top of the movable rod 10-1. When the second motor rotates forward and backward, the drive gear 10-2 drives the movable rod 10-1 to move up and down, realizing precise stroke control of the telescopic arm 10, which is convenient for adapting to different soil depths or seedling sizes.

[0056] The opening and closing claw 11 includes a mounting frame 11-1, a claw body 11-2, and a torsion spring 11-3. The mounting frame 11-1 is fastened to the bottom of the movable rod 10-1 of the telescopic arm 10; the claw body 11-2 consists of multiple arc-shaped metal plates evenly spaced around the mounting frame 11-1, and its top is hinged to the mounting frame 11-1 by a pin; a torsion spring 11-3 is installed at the hinge point between each claw body 11-2 and the mounting frame 11-1. The spring keeps the claw body 11-2 closed when there is no external force, ensuring that the seedlings will not fall off during transportation.

[0057] The opening and closing claw drive device 12 includes a sliding sleeve 12-1, pull ropes 12-2, and a telescopic cylinder 12-3. The sliding sleeve 12-1 is sleeved on the outside of the movable rod 10-1 and can slide along its axial direction; the number of pull ropes 12-2 is the same as the number of claw bodies 11-2, with one end of each pull rope 12-2 fixed to the middle or lower part of the corresponding claw body 11-2, and the other end connected to the sliding sleeve 12-1; the telescopic cylinder 12-3 is fixedly installed on the movable rod 10-1, and its telescopic end is connected to the sliding sleeve 12-1. When the telescopic cylinder 12-3 shortens, it drives the sliding sleeve 12-1 to move upward, tightening all the pull ropes 12-2, overcoming the elastic force of the torsion spring 11-3, and causing the claw bodies 11-2 to open synchronously; when the telescopic cylinder 12-3 extends, the sliding sleeve 12-1 moves downward, the pull ropes 12-2 loosen, and the claw bodies 11-2 automatically close under the action of the torsion spring 11-3. This structure eliminates the need for individual drive components for each claw, simplifying the mechanical structure, reducing the failure rate, and ensuring synchronous and reliable opening and closing actions.

[0058] Furthermore, an automatic watering device 13 is installed on the frame 1; the automatic watering device 13 includes a water tank 13-1 and a hose 13-2. The water tank 13-1 is fixedly installed on the top of the frame 1 and contains a water pump; one end of the hose 13-2 is connected to the water pump outlet, and the other end is laid along the inside or outside of the telescopic arm 10, extending into the opening and closing claw 11. Simultaneously with the opening and closing claw 11 opening and releasing the peony seedlings, the water pump is activated, and water is quantitatively injected into the planting hole through the hose 13-2, achieving integrated "planting-watering" operation. This design not only saves subsequent manual watering procedures but also provides moisture to the seedling roots at the moment of transplanting, alleviating transplanting stress and significantly improving the survival rate, making it particularly suitable for field operations in arid or semi-arid regions.
