Description

Technical Field

[0001] This invention relates to the field of scallion seedling transplanting technology, and in particular to a seedling supply mechanism, equipment and method for scallion seedling transplanting. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Taking Zhangqiu scallion transplanting as an example, the current scallion transplanting work has gradually shifted from traditional, complex manual operations to semi-automatic or automatic machinery. Fully automatic transplanters are only used for transplanting seedlings from trays, while the machinery suitable for transplanting scallion seedlings from the field after seed propagation is mainly finger-clamp, chain-clamp, and duckbill type. Due to the special nature of mechanized transplanting devices and their operating principles, it is difficult to guarantee the quality of scallion seedling planting during transplanting. In particular, most scallion transplanters on the market are powered by tractors, and to adapt to the tractor's wheel track, they are mostly of a complex structure, making operation difficult and compromising transplanting quality.

[0004] Most transplanters on the market that are suitable for transplanting scallion seedlings from the field after the scallion seedlings have been propagated are semi-automatic transplanters. They rely on manual seedling separation and supply, which is labor-intensive and makes it difficult to guarantee the quality of seedling separation and the spacing between transplanted plants, resulting in a low rate of upright transplanting. In order for transplanters to be recognized and accepted by users, it is necessary to design seedling feeding devices and upright planting devices on the transplanters.

[0005] Since current transplanting methods are mainly suitable for transplanting small seedlings and require manual assistance in placing the seedlings, for transplanting large seedlings, especially scallions, which are about 180mm long and about 10mm in diameter and have a certain weight, the traditional small seedling transplanting method requires workers to assist in placing the seedlings for a long time, which is a problem of high labor intensity. This is mainly because the seedling supply mechanism in the existing transplanting machine does not meet the seedling supply requirements of scallions.

[0006] Of course, there are also existing technologies for automatic transplanting machines for scallion seedlings, which are designed for thinner scallion seedlings less than 10cm in length. They require a seedling tray for transplanting and are not suitable for longer scallion seedlings. Moreover, the overall structure is complex. The distance between the power mechanism and some other mechanisms is too far, which affects the response accuracy of the overall structure. The flexible disc, as the planting mechanism, exerts a large squeezing force on the scallion seedlings, which can easily lead to damage to the seedlings. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a seedling supply mechanism for transplanting scallion seedlings, which can realize automatic seedling supply without the need for manual assistance.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0009] A seedling supply mechanism for transplanting scallion seedlings includes a support ring and a support component. The support ring is hollow and can be inserted into the support shaft of a scallion seedling transplanting device. The support component is located circumferentially around the support ring, and there is a gap between the support component and the support ring. A protective component is circumferentially fitted around the scallion seedling. Multiple scallion seedlings are arranged closely between the support component and the support ring in a predetermined manner. Both sides of the scallion seedlings protrude from the end side of the support component. An opening can be formed on one side of the support component under the action of external force. The width of the opening is adapted to the diameter of a single scallion seedling, and the length of the opening is the same as the thickness of the support component.

[0010] As described above, the seedling supply mechanism arranges the scallion seedlings closely between the support component and the support ring. The support component can form an opening. Before the opening is formed, the seedling supply mechanism as a whole is easy to move and install. After the opening is formed, the scallion seedlings are supplied downward from the opening, realizing the supply of longer and larger diameter scallion seedlings without the need for manual assistance in supplying seedlings during the machine's movement.

[0011] As described above, in a seedling supply mechanism for transplanting scallion seedlings, the supporting component is circular or hexagonal, and the protective component is a protective ring. The shape of the protective ring is the same as that of the supporting component, so as to ensure the spacing between two adjacent scallion seedlings and to ensure the transplanting distance between scallions during the transplanting process.

[0012] The support ring is a flexible support ring or a flexible component is provided on the outer circumferential surface of the support ring to avoid damaging the scallion seedlings.

[0013] Secondly, this invention discloses a fully automatic scallion seedling transplanting equipment, including a frame, a power mechanism, a walking mechanism, and a furrow opener. The frame supports a mounting plate, and the mounting plate is provided with a support shaft. The support shaft cooperates with the aforementioned seedling supply mechanism for scallion seedling transplanting. A seedling guide mechanism is provided at the mounting plate, and the opening of the support component is aligned with the upper side of the seedling guide mechanism. A planting mechanism is provided on the frame and is rotatable relative to the frame. The mounting plate is located in front of the power mechanism. The walking mechanism, the seedling guide mechanism, and the planting mechanism are all connected to the power mechanism, and a controller is connected to the power mechanism.

[0014] As described above, the transplanting equipment has a reasonable overall structure. The seedling supply mechanism supplies seedlings to the seedling guide mechanism, the seedlings enter the seedling guide mechanism, and then the transplanting mechanism transplants the seedlings. The overall structure is simple, without a complicated seedling supply mechanism, and can achieve automated operation without the need for personnel assistance.

[0015] As described above, in a fully automatic scallion seedling transplanting equipment, the planting mechanism is located in front of the seedling supply mechanism for scallion seedling transplanting. A protective component is provided in the area of ​​the planting mechanism that contacts the scallion seedling. When the protective component contacts the scallion seedling, it can protect the scallion seedling to the greatest extent, reduce the squeezing force on the scallion seedling, and reduce the damage rate of the scallion seedling.

[0016] A limiting component is installed at the frame. The limiting component can be inserted into the inside of the planting mechanism. The limiting component is located on the upper side of the planting mechanism and on the front side of the seedling supply mechanism.

[0017] As described above, a fully automatic scallion seedling transplanting equipment includes a planting mechanism comprising two oppositely arranged flexible discs, a clamping mechanism on the outer side of the flexible discs, the flexible discs being rotatable, and the protective component being a flexible protrusion. A flexible protrusion is provided on the inner surface of the flexible disc, and multiple flexible protrusions are provided along the radial direction of the flexible disc. The length of the flexible protrusion is less than the radius of the flexible disc.

[0018] The limiting component is a limiting fork, which allows the flexible disk to open so that the protective component can catch the scallion seedlings.

[0019] As described above, a fully automatic scallion seedling transplanting equipment, considering the rationality of the structural layout, includes a first support frame, which is arranged around the mounting plate and perpendicular to the mounting plate. The first support frame is connected to a second support frame, and depth-limiting wheels are movably arranged on both sides of the second support frame. A third support frame is arranged below the first support frame, and the mounting plate is fixed to the third support frame. The third support frame supports the planting mechanism. A furrow opener is also installed on the bottom side of the third support frame. The furrow opener is placed in front of the depth-limiting wheels, and the depth-limiting wheels are placed between the furrow opener and the traveling mechanism.

[0020] A soil-covering wheel is installed on the front side of the ditcher on the frame. The circumferential surface of the soil-covering wheel has a first protrusion, which is a triangular protrusion. The sharp corner of the triangular protrusion is oriented away from the central axis of the soil-covering wheel. A second protrusion and a third protrusion are also provided on the side of the soil-covering wheel away from the third support. The second and third protrusions are spaced apart on the circumferential surface of the soil-covering wheel. The third protrusion is set lower than the second protrusion and extends beyond the side of the soil-covering wheel. The arrangement of the first, second, and third protrusions, and the second and third protrusions spaced apart on the circumferential surface of the soil-covering wheel, can provide sufficient power for the planting mechanism, prevent slippage during the operation of the transplanting device, and achieve better planting results.

[0021] As described above, in a fully automatic scallion seedling transplanting equipment, the second bracket is connected to a fourth bracket on the side away from the first bracket. The fourth bracket supports the power mechanism. The walking mechanism is located below the fourth bracket and includes wheels. A support arm is provided below the fourth bracket, and wheels are respectively provided on both sides of the support arm. The two wheels are connected by the same rotating shaft, and the rotating shaft is connected to the power mechanism through a first transmission component.

[0022] As described above, in a fully automatic scallion seedling transplanting equipment, the output end of the power mechanism is provided with a second transmission component, which is installed on the mounting plate. The second transmission component is connected to a third transmission component, and the third transmission component is separately connected to the planting mechanism. In this way, the power mechanism is close to each structural component that needs to be driven, ensuring the response speed of each structural component.

[0023] As described above, a fully automatic scallion seedling transplanting equipment includes a scallion seedling guiding mechanism comprising two oppositely arranged conveyor belts, which are arranged around an active roller and a driven roller. The active roller is connected to a power source. The conveyor belts are bent, and a guide block is located on the outside of the bend in the conveyor belt. One end of the guide block is fixed to the mounting plate.

[0024] Thirdly, the present invention also provides a method for operating a seedling supply mechanism for transplanting scallion seedlings, comprising the following:

[0025] Place the frame in the furrow;

[0026] A seedling supply mechanism for transplanting scallion seedlings is installed on an installation plate for support. An opening slides out on the bottom side of the support component, and the opening of the support component is aligned with the upper side of the scallion seedling guide mechanism.

[0027] The controller controls the power mechanism to work, and the power mechanism drives the walking mechanism to start working, so that the frame can walk along the furrows. During the walking process, the furrow opener opens the furrows.

[0028] During the frame movement, the power mechanism drives the scallion seedling guiding mechanism and the planting mechanism to start working. The scallion seedlings enter the scallion seedling guiding mechanism through the opening of the support component under the action of gravity, and the scallion seedling guiding mechanism sends the scallion seedlings into the planting mechanism.

[0029] The planting mechanism rotates relative to the frame, and after rotating to a set angle, it sends the scallion seedlings into the ditch.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1) The seedling supply mechanism provided by this invention arranges the scallion seedlings closely between the supporting component and the supporting ring. The supporting component can form an opening. Before the opening is formed, the seedling supply mechanism as a whole is easy to move and install. After the opening is formed, the scallion seedlings are supplied downwards from the opening, realizing the supply of longer and larger diameter scallion seedlings without the need for manual assistance in supplying seedlings during the machine's movement.

[0032] 2) The transplanting equipment provided by this invention has a reasonable overall structure and optimal layout, ensuring rapid power transmission. The seedling supply mechanism supplies seedlings to the seedling guide mechanism, the seedlings enter the seedling guide mechanism, and then the transplanting mechanism transplants the seedlings. The overall structure is simple, without a complicated seedling supply mechanism, and can achieve automated operation without human assistance. The operator only needs to set up the seedling supply mechanism. The whole system can achieve automatic walking in small furrows and automatic transplanting of scallions, which helps to reduce the labor cost of scallion transplanting and improve the upright rate of transplanted scallions.

[0033] 3) The planting mechanism of the present invention includes a flexible disc, which is rotatable relative to the frame. The flexible disc receives the scallion seedlings transported by the seedling guide mechanism. The flexible disc rotates and, under the action of the clamping mechanism, drives the scallion seedlings to the ground. When it moves to the release point of the flexible disc, the scallion seedling is planted. Then, the soil covering wheel covers and compacts the soil to achieve upright, low-damage, and anti-slip planting of the scallion seedlings.

[0034] 4) The frame structure of this invention is reasonably designed. The frame supports the mounting plate, which is located in front of the power mechanism. This allows the seedling supply mechanism, the seedling guiding mechanism, and the planting mechanism to be located close to the power mechanism. Since the power mechanism drives some of the above mechanisms through the transmission components, it facilitates the rapid transmission of force and ensures the response speed of each mechanism.

[0035] 5) In this invention, flexible protrusions are provided on the inner side of the flexible disc. When the flexible protrusions are in contact with the scallion seedlings, they can protect the scallion seedlings to the greatest extent, reduce the squeezing force on the scallion seedlings, and reduce the damage rate of the scallion seedlings.

[0036] 6) In this invention, the circumferential surface of the soil covering wheel is provided with a first protrusion and a second protrusion. The second protrusion is located on the outer side of the soil covering wheel. The provision of the first protrusion and the second protrusion can provide sufficient power for the planting mechanism, prevent slippage during the operation of the transplanting device, and achieve better planting results.

Detailed Implementation

[0051] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0052] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0053] As described in the background section, the existing scallion seedling transplanting mechanism has a complex structure. In order to solve the above technical problems, the present invention proposes a seedling supply mechanism for scallion seedling transplanting.

[0054] Example 1

[0055] In a typical embodiment of the present invention, reference is made to Figure 5 and Figure 6 As shown, a seedling supply mechanism for transplanting scallion seedlings includes a support ring 24 and a support component 23. The support ring 24 is hollow and can be inserted into the support shaft of the scallion seedling transplanting equipment. The support component 23 is located circumferentially around the support ring 24, and the support component 23 and the support ring are spaced apart. Multiple scallion seedlings 22 are circumferentially covered with protective parts and are arranged closely between the support component 23 and the support ring 24 in a predetermined manner. Both sides of the scallion seedlings 22 protrude from the end sides of the support component 23. The protruding length of the scallion seedlings 22 from one end of the support component 23 is greater than the protruding length of the scallion seedlings from the other end of the support component 23. An opening can be formed on one side of the support component 23 under the action of external force. The width of the opening is adapted to the diameter of a single scallion seedling 22, and the length of the opening is the same as the thickness of the support component 23.

[0056] Among them, the support ring 24 is a flexible support ring or a flexible component is provided on the outer circumferential surface of the support ring. The flexible support ring can be a rubber support ring, and the flexible component can be made of rubber material to avoid damaging the scallion seedlings.

[0057] In some examples, the support component 23 is circular, and in some examples, the support component 23 is hexagonal. The support component 23 is made of cardboard, and one side of the support component is provided with a notch. After the support component is fixed to the transplanting equipment, the notch is torn open under the action of external force or the notch is cut open with a tool to form an opening on the bottom side of the support component. Under the action of gravity, the scallion seedlings fall one by one from the opening.

[0058] Specifically, the protective component 25 is a protective ring, which can be made of protective paper. The protective component can be buried in the soil together with the scallion roots during transplanting. It is biodegradable. The length of the protective component 25 is the same as the height of the support ring. The shape of the protective ring is the same as the shape of the support component. The protective ring fits snugly against the scallion seedling. When the support component 23 is hexagonal, the protective ring is also hexagonal to ensure the spacing between two adjacent scallion seedlings, thereby ensuring the transplanting distance between scallions during transplanting.

[0059] The seedling supply mechanism provided in this embodiment arranges the scallion seedlings 22 closely between the support component and the support ring. The support component can form an opening. Before the opening is formed, the seedling supply mechanism as a whole is easy to move and install. After the opening is formed, the scallion seedlings 22 are supplied downward from the opening, realizing the supply of longer and larger diameter scallion seedlings without the need for manual assistance in supplying seedlings during the machine's movement.

[0060] Example 2

[0061] This embodiment provides a fully automated scallion seedling transplanting equipment, see reference. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a frame 1, which is equipped with a power mechanism 2, a walking mechanism 11, and a furrow opener 8. The frame 1 supports a mounting plate 3, which is equipped with a support shaft. The support shaft cooperates with a seedling supply mechanism for transplanting scallion seedlings as described in Embodiment 1. A scallion seedling guide mechanism 9 is provided at the mounting plate 3. The opening of the support component 23 is aligned with the upper side of the scallion seedling guide mechanism 9. The frame 1 is equipped with a planting mechanism 6, which is rotatable relative to the frame 7. The mounting plate 3 is located in front of the power mechanism. The walking mechanism 11, the scallion seedling guide mechanism 9, and the planting mechanism 6 are all connected to the power mechanism 2. A controller is connected to the power mechanism. The controller is a PLC controller or other type of controller.

[0062] It should be noted that, from the front to the rear of the frame 1, the covering wheel 5, the trencher 8, the depth limiting wheel 10 and the traveling mechanism 11 are arranged in sequence. The covering wheel 5 is located on both sides of the frame and is inclined outward relative to the frame 1. The trencher 8 is located below the middle of the frame 1. The depth limiting wheel 10 is located on one side of the frame 1. The traveling mechanism 11 is set below the depth limiting wheel 10. The covering wheel 5 is set above the trencher 8. The frame 1 is equipped with a handrail 7 above the power mechanism.

[0063] The furrow opener 8 includes two furrowing plates with a spacing between them. After the planting mechanism rotates the scallion seedlings at a set angle, it delivers the scallion seedlings to the area between the two furrowing plates. The bottom of the planting mechanism is higher than the bottom of the furrow opener 8.

[0064] Considering the rationality of the structural layout, the frame 1 includes a first support 13, which is arranged around the mounting plate 3 and perpendicular to the mounting plate 3. The first support 13 is connected to the second support 14. Depth limiting wheels 10 are movably arranged on both sides of the second support 14. A third support 15 is arranged below the first support. The mounting plate 3 is fixed to the third support 15. The third support 15 supports the planting mechanism 6. A furrow opener 8 is also installed on the bottom side of the third support 15. The furrow opener is placed in front of the depth limiting wheel, and the depth limiting wheel is placed between the furrow opener and the traveling mechanism.

[0065] Specifically, the first bracket 13 is a frame-shaped frame, and the width of the first bracket 13 on the side of the mounting plate 3 is greater than the width of the front side of the first bracket. The bottom of the first bracket near the back side of the mounting plate is connected to the second bracket. The second bracket 14 is a vertical frame, and the side of the second bracket 14 is provided with a connecting rod connected to the same depth limiting wheel.

[0066] Among them, a limiting component 20 is provided at the first bracket 13, for reference. Figure 7 As shown, the limiting component 20 is fixed to the first bracket 13 by the connecting frame 26. The limiting component is located above the front of the flexible disc 19. The limiting component 20 can be inserted into the inner side of the planting mechanism 6. The limiting component 20 is specifically a limiting fork. The limiting fork is a rigid structural component. The two sides of the limiting fork are located between the two flexible discs. When the flexible disc is clamped, the setting of the limiting fork can make the upper side of the flexible disc open so as to catch the scallion seedling through the flexible disc.

[0067] refer to Figure 3 As shown, the transverse cross-section of the mounting plate 3 is U-shaped. One side of the mounting plate 3 is used to fix the scallion seedling guide mechanism 9 and the seedling supply mechanism 4, while the other side of the mounting plate 3 supports the third transmission component. The mounting plate is located between the power mechanism and the seedling supply mechanism.

[0068] In this embodiment, the side of the second bracket 14 away from the first bracket is connected to the fourth bracket 16. The fourth bracket 16 is set lower than the first bracket and is also a frame. The fourth bracket supports the power mechanism 2, which is specifically an engine. The walking mechanism is located below the fourth bracket. The walking mechanism 11 includes wheels. A support arm is set below the fourth bracket, and wheels are set on both sides of the support arm. The two wheels are connected by the same rotating shaft. The rotating shaft is connected to the power mechanism through a first transmission component. The first transmission component is a gear transmission component, which is located inside the support arm to realize the rotation of the wheels.

[0069] refer to Figure 2As shown, the output end of the power mechanism 2 is provided with a second transmission component 17, which is a belt transmission component. The output pulley of the second transmission component is also connected to a third transmission component 21. The third transmission component 21 includes a chain transmission component. The driving wheel and driven wheel of the third transmission component are installed on the back side of the mounting plate. The third transmission component is connected to the planting mechanism. A driven shaft 18 is provided at the driven wheel of the third transmission component. The driven shaft 18 extends beyond the mounting plate 3. The part of the driven shaft 18 that extends beyond the mounting plate is connected to the planting mechanism through a bevel gear transmission component to drive the planting mechanism to achieve rotational movement. In this way, the power mechanism is close to each structural component that needs to be driven, ensuring the response speed of each structural component.

[0070] Regarding the covering wheel, the covering wheel is supported by a third support, see reference. Figure 8 and Figure 9 As shown, the circumferential surface of the covering wheel 5 is provided with a first protrusion 28, which is a triangular protrusion. The triangular protrusions are evenly distributed on the circumferential surface of the covering wheel, and the sharp corners of the triangular protrusions are set in a direction away from the central axis of the covering wheel 5. The side of the covering wheel 5 away from the third support 15 is also provided with a second protrusion 29 and a third protrusion 30. The third protrusion 30 is set lower than the second protrusion 29. The second and third protrusions are spaced apart on the circumferential surface of the covering wheel. The third protrusion 30 is set beyond the side of the covering wheel 5. The second protrusion 29 has a set height and the side of the second protrusion 29 is flush with the side of the covering wheel 5. The second protrusion 29 and the third protrusion are both rectangular protrusions. The distance between two adjacent second protrusions 29 is greater than the distance between two adjacent first protrusions. The arrangement of the first protrusion 28, the second protrusion 29 and the third protrusion 30 can provide sufficient power for the planting mechanism, prevent slippage during the operation of the transplanting device, and achieve better planting results.

[0071] In this embodiment, the scallion seedling guiding mechanism 9 includes two oppositely arranged conveyor belts. The conveyor belts are arranged around the active roller and the driven roller. Both the active roller and the driven roller are mounted on the mounting plate. The active roller is connected to the power mechanism. The conveyor belts are bent. The guide block 12 is located on the outside of the bend of the conveyor belt. One end of the guide block 12 is fixed to the mounting plate. The side of the guide block that contacts the conveyor belt is an arc-shaped surface.

[0072] Specifically, the scallion seedling guiding mechanism 9 is driven by a power source installed on the back side of the mounting plate. The power source is a rotary motor, which drives the two active rollers of the scallion seedling guiding mechanism to rotate. (Refer to...) Figure 11 As shown, the two drive rollers are connected by a sprocket drive assembly, and the drive sprocket 31 of the sprocket drive assembly meshes with the output gear 33 at the power source through gears.

[0073] In this embodiment, the planting mechanism 6 is located on the front side of a seedling supply mechanism for transplanting scallion seedlings (hereinafter referred to as the seedling supply mechanism). The area inside the planting mechanism that comes into contact with the scallion seedlings is provided with protective components. When the protective components receive the scallion seedlings, they can protect the scallion seedlings to the greatest extent, reduce the squeezing pressure on the scallion seedlings, and reduce the damage rate of the scallion seedlings. The flexible disc 19 is made of rubber, so it can maximize the uprightness of the scallion seedlings and reduce the damage rate of the scallion seedlings when planting them.

[0074] Specifically, the planting mechanism 6 includes two oppositely arranged flexible discs 19, each with a clamping mechanism. The flexible discs are rotatable, and the protective components are flexible protrusions. (See reference...) Figure 10 As shown, a flexible protrusion 32 is provided on the inner surface of the flexible disk 19 near the edge of the flexible disk. The flexible protrusion 32 is provided along the radial direction of the flexible disk. The flexible protrusion 32 has a set height and a set length. The flexible protrusion is a rubber protrusion. The angle between two adjacent flexible protrusions is less than or equal to 10°.

[0075] It should be noted that the planting mechanism using a flexible disc is existing technology. A clamping mechanism 27 is set on the outside of the flexible disc. The clamping mechanism 27 can realize the directional transport of the scallion seedlings between the clamping pad and the release point. The clamping mechanism is existing technology and will not be described in detail.

[0076] The transplanting equipment provided in this embodiment supplies seedlings to the seedling guide mechanism. The seedlings enter the seedling guide mechanism and are then transplanted by the planting mechanism. The overall structure is simple, without a complex seedling supply mechanism, enabling automated operation without human assistance. It achieves the agronomical requirements for seedling transplanting by independently walking in the trench, reducing labor costs and improving the uprightness of transplanted seedlings. Moreover, the overall structure is reasonably designed, with cleverly arranged components to achieve effective seedling supply and transplanting, while ensuring effective drive of each component by the power mechanism.

[0077] Example 3

[0078] This embodiment provides a working method for a seedling supply mechanism for transplanting scallion seedlings, including the following:

[0079] Place frame 1 in the furrow;

[0080] The seedling supply mechanism 4 is installed on the mounting plate 3 for support, and an opening slides out on the bottom side of the support component 23, with the opening of the support component 23 aligned with the upper side of the scallion seedling guide mechanism.

[0081] The transplanting equipment moves along the direction of the furrow in the ridge using the power provided by the engine. The scallion seedlings enter the scallion seedling guide mechanism 9 through the opening of the support component 23 under the action of gravity, and the scallion seedling guide mechanism 9 sends the scallion seedlings into the planting mechanism 6.

[0082] When the flexible disc 19 in the planting mechanism 6 receives the scallion seedlings released by the seedling guide mechanism 9, the flexible disc will be clamped at the contact point of the scallion seedlings under the action of the clamping mechanism 27. When the flexible disc 19 rotates, the clamped scallion seedlings will rotate with the disc. When the scallion seedlings move to the designated position, the clamping force of the clamping device disappears and the scallion seedlings fall upright into the trench opened by the trench opener 8. Then the soil covering wheel 5 completes the soil covering and compaction of the scallion seedlings, completing one scallion seedling transplanting operation.

[0083] Once all the scallion seedlings have been supplied to the seedling supply unit, the seedling supply unit can continue to operate by replacing it with a new seedling supply unit 4.

[0084] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
