Description

Upper clamping mechanism, grafting device and grafting system Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to upper clamping mechanisms, grafting devices and grafting systems. Background Technology

[0002] Planting is becoming increasingly regionalized and specialized, with continuous cropping and replanting being quite common. Vegetable grafting is an effective technique for preventing soil-borne diseases. It uses resistant plants as rootstocks and cultivated varieties as scions, which can preserve the excellent characteristics of the plants, enhance disease resistance, and improve the stress resistance and yield of grafted seedlings. Currently, vegetable grafting is still largely done manually.

[0003] To improve grafting efficiency, some automated grafting machines exist in the existing technology. However, the clamping mechanism of the existing automated grafting machines has problems such as unstable transportation, complex structure, large space occupation, and high production cost, which limits the widespread application of automated grafting technology. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, this application provides an upper clamping mechanism, a grafting device, and a grafting system, which aim to improve the transport stability of the upper clamping mechanism and reduce the space occupied and production cost of the upper clamping mechanism, thereby enabling the widespread application of the grafting device.

[0005] The technical solution adopted in this application to solve its problem is:

[0006] The upper clamping mechanism includes: a frame; a guide rail disposed on the frame for transporting a long strip-shaped grafting clip; a dividing component for cutting a portion of the grafting clip to form a grafting clip; a clamping jaw that can switch between a clamping state and an open state, wherein when the clamping jaw is switched to the clamping state, it can open the grafting clip, and when the clamping jaw is switched to the open state, it can allow the grafting clip to enter the clamping jaw or release the clamping of the grafting clip to make the grafting clip clamped; and a first roller rotatably disposed on the frame, wherein the first roller is used to contact the grafting clip to move the grafting clip along the guide rail, thereby pushing the grafting clip into the clamping jaw when switched to the open state.

[0007] According to some embodiments of this application, the first roller includes a first cone and a second cone connected to each other; the cross-section of the first cone in the direction perpendicular to the axis gradually decreases in the direction away from the second cone; the cross-section of the second cone in the direction perpendicular to the axis gradually decreases in the direction away from the first cone.

[0008] According to some embodiments of this application, the guide rail is provided with a transport groove, the transport groove including a first inclined groove, a second inclined groove and a groove opening, the first inclined groove and the second inclined groove are connected and together form a figure-eight structure, and the groove opening is connected to the junction of the first inclined groove and the second inclined groove.

[0009] According to some embodiments of this application, the upper clamping mechanism further includes a second roller, which is rotatably mounted on the frame. The second roller and the first roller are arranged opposite to each other, and the second roller and the first roller are respectively used to press against both sides of the grafting clamp.

[0010] According to some embodiments of this application, the guide rail is slidably disposed on the frame, and the guide rail can slide in a direction perpendicular to the axis of the first roller to adjust its position.

[0011] According to some embodiments of this application, the upper clamping mechanism further includes a feeding section disposed on the frame; the guide rail includes a first rail section and a second rail section spaced apart, the first roller is located between the first rail section and the second rail section, the first rail section is relatively close to the feeding section and relatively far away from the dividing component, and the second rail section is relatively close to the dividing component and relatively far away from the feeding section.

[0012] According to some embodiments of this application, the upper clamping mechanism further includes an operating table and a first driving member. The operating table has an operating port. The first driving member and the clamping claw are connected in a transmission manner. The first driving member can drive the clamping claw to switch between the clamping state and the open state. The first driving member can also drive the clamping claw to move between a first position and a second position. When the clamping claw switches to the open state and moves to the first position, the end of the clamping claw is opposite to the end of the guide rail, thereby allowing the grafting clip to enter the clamping claw. When the clamping claw switches to the clamping state and moves to the second position, the clamping claw extends out of the operating port. The clamping claw opens the grafting clip and allows the scion and rootstock to enter the grafting clip. The clamping claw can switch back to the open state to release the clamping of the grafting clip and make the grafting clip clamp tight.

[0013] According to some embodiments of this application, the operating port and the first driving member are offset, and the projection of the first driving member onto the operating table is located outside the operating port.

[0014] According to some embodiments of this application, the gripper includes a first gripping finger and a second gripping finger disposed opposite to each other, both the first gripping finger and the second gripping finger being convexly connected to the first driving member; the first driving member can drive the first gripping finger and the second gripping finger to move away from each other so that the gripper switches to an open state; the first driving member can drive the first gripping finger and the second gripping finger to move closer to each other so that the gripper switches to a clamping state.

[0015] In addition, this application also provides a grafting device, which includes the upper clamping mechanism as described above, and the grafting device also includes a seedling cutting mechanism.

[0016] In addition, this application also provides a grafting system, including the grafting device as described above, and a grafting clamp, a portion of which can be divided by the dividing component to form a grafting clamp; the grafting clamp includes a clamping post, a first clamping leg and a second clamping leg, the clamping post being connected between the first clamping leg and the second clamping leg; the cross-section of the clamping post perpendicular to the axial direction is circular, elliptical, teardrop-shaped or U-shaped.

[0017] In summary, the upper clamping mechanism, grafting device, and grafting system provided in this application have at least the following technical advantages:

[0018] The grafting clip is placed on a guide rail. The dividing component can cut off a portion of the grafting clip to serve as the grafting clamp. When clamping is required, the jaws can first switch to the open state. The first roller rotates to push the grafting clip along the guide rail. The grafting clip pushes the cut-off grafting clip into the jaws, at which point the grafting clip is clamped. Then, the jaws can switch to the holding state to open the grafting clip. After the operator places the scion and rootstock into the grafting clip, the jaws switch back to the open state to re-clamp the grafting clip, thus completing the grafting process (joining the scion and rootstock together). The operation is simple, convenient, and relatively precise, with good grafting results. It also reduces the skill requirements and labor intensity of the operators. Furthermore, using the first roller to transport the grafting clip improves the continuity and stability of transportation, allowing for the transport of longer grafting clips, further improving grafting efficiency. The overall structure of this clamping mechanism is also relatively simple and compact, occupying little space and having low production costs, which is conducive to the widespread application of grafting devices.

[0036] The present application will now be described in further detail with reference to the accompanying drawings.

[0037] Example 1

[0038] Please refer to Figures 1 to 8. This embodiment discloses an upper clamping mechanism. The upper clamping mechanism includes a frame 1, a guide rail 2, a dividing component 3, a clamping claw 4, and a first roller 5. The guide rail 2 is disposed on the frame 1 and is used to transport a long strip-shaped grafting clip 7. The dividing component 3 is used to cut a portion of the grafting clip 7 to form a grafting clip 71. The clamping claw 4 can switch between a clamping state and an open state. When the clamping claw 4 is switched to the clamping state, it can open the grafting clip 71. When the clamping claw 4 is switched to the open state, it can allow the grafting clip 71 to enter the clamping claw 4 or release the clamping of the grafting clip 71 to make the grafting clip 71 clamp. The first roller 5 is rotatably disposed on the frame 1. The first roller 5 is used to contact the grafting clip 7 to make the grafting clip 7 move along the guide rail 2, thereby pushing the grafting clip 71 into the clamping claw 4 when it is switched to the open state.

[0039] The clamping mechanism provided in this embodiment includes a grafting clip 7 placed on a guide rail 2. A dividing component 3 can cut off a portion of the grafting clip 7 to serve as a grafting clip 71. When clamping is required, the jaws 4 can first switch to an open state. The first roller 5 rotates to push the grafting clip 7 along the guide rail 2, causing the grafting clip 7 to push the cut-off grafting clip 71 into the jaws 4. At this time, the grafting clip 71 is in a clamped state. Subsequently, the jaws 4 can switch to a holding state to open the grafting clip 71. After the operator places the scion and rootstock into the grafting clip 71, the jaws 4 switch back to a holding state. The grafting process (joining the scion and rootstock together) can be completed by opening the grafting clamp 71 to re-clamp it. The operation is simple, convenient and relatively precise, with good grafting effect. It also reduces the skill requirements and labor intensity of the operators. Furthermore, using the first roller 5 to transport the grafting clamp 7 can improve the continuity and stability of transportation, thereby allowing the transportation of longer grafting clamps 7, which further improves grafting efficiency. The overall structure of the upper clamping mechanism is also relatively simple and compact, occupies less space, and has a lower production cost, which is conducive to the widespread application of grafting devices.

[0040] As shown in Figure 4, specifically in this embodiment, the upper clamping mechanism further includes a second driving member 20, which is disposed on the frame 1. The second driving member 20 is connected to the first roller 5 and is used to drive the first roller 5 to rotate.

[0041] As shown in Figures 4, 5, and 8, preferably, in this embodiment, the first roller 5 includes a first cone 51 and a second cone 52 connected to each other. The first cone 51 and the second cone 52 are respectively used to contact the two sides of the grafting clamp 7 arranged at an angle. The cross-section of the first cone 51 in the direction perpendicular to the axis gradually decreases in the direction away from the second cone 52; the cross-section of the second cone 52 in the direction perpendicular to the axis gradually decreases in the direction away from the first cone 51. This design results in a specific shape change in the cross-section of the first roller 5 in the direction perpendicular to the axis. Due to the gradual change in cross-section, better contact between the first roller 5 and the grafting clamp 7 is facilitated. During rolling, the first roller 5 can apply pressure to the grafting clamp 7 more evenly, thereby avoiding transportation instability caused by uneven pressure. This allows the first roller 5 to more effectively push the grafting clamp 7 along the guide rail 2, improving the continuity and stability of transportation, extending the service life of the first roller 5, and reducing maintenance costs.

[0042] As shown in Figure 8, more preferably, in this embodiment, in order to enhance the friction between the first roller 5 and the grafting clamp 7, the peripheral sidewall of the first cone 51 is provided with a plurality of spaced first grooves 511, and the peripheral sidewall of the second cone 52 is provided with a plurality of spaced second grooves 521. Thus, the design of these grooves not only increases the surface roughness of the first roller 5, but also provides additional gripping points, so that the first roller 5 can more effectively grip the surface of the grafting clamp 7 during rolling. This enhanced friction not only improves the continuity and stability of transportation, but also enables the first roller 5 to better adapt to grafting clamps 7 of different materials and thicknesses.

[0043] It should be noted that the number, depth and spacing of the grooves in the first cone 51 and the second cone 52 can be adjusted according to actual needs. By optimizing these parameters, we can further improve the performance of the roller to meet the specific requirements of different grafting operations. For example, increasing the number and depth of the grooves can enhance the friction, while adjusting the spacing of the grooves can optimize the rolling effect of the roller.

[0044] As shown in Figures 3, 4, 5, and 6, preferably, in this embodiment, the guide rail 2 is provided with a transport groove 23, which includes a first inclined groove 231, a second inclined groove 232, and a groove opening 233. The first inclined groove 231 and the second inclined groove 232 are connected and together form a figure-eight structure. The groove opening 233 is connected to the junction of the first inclined groove 231 and the second inclined groove 232. In this way, the transport groove 23 can more effectively adapt to the transport needs of the grafting clip 7, especially when handling grafting clips 7 of different sizes and shapes. In addition, the figure-eight structure of the transport groove 23 also has a certain guiding function. During the rolling of the first roller 5, it can guide the grafting clip 7 to move along the set direction, avoiding transport problems caused by path deviation. This guiding function not only improves the accuracy of grafting operations, but also reduces errors and waste caused by improper operation.

[0045] It should be noted that the design of the transport trough 23 can be further adjusted and optimized according to actual needs. For example, parameters such as the inclination angle of the first inclined trough 231 and the second inclined trough 232, and the size and shape of the trough opening 233 can be adjusted to adapt to the specific requirements of different grafting operations. By optimizing these parameters, we can further improve the transport efficiency and adaptability of the guide rail 2.

[0046] As shown in Figures 3, 4 and 5, preferably, in this embodiment, the upper clamping mechanism further includes a second roller 6, which is rotatably mounted on the frame 1. The second roller 6 and the first roller 5 are arranged opposite to each other, and the second roller 6 and the first roller 5 are respectively used to press against both sides of the grafting clamp 7. This arrangement allows the second roller 6 and the first roller 5 to effectively press against both sides of the grafting clip 7. In practical applications, when the grafting clip 7 is fed into the upper clamping mechanism, the first roller 5 and the second roller 6 apply pressure simultaneously, ensuring the grafting clip 7 remains stable during transportation. This double-sided pressing design not only improves the stability of the grafting clip 7 during transportation but also effectively prevents it from shifting or slipping during transport. Furthermore, the introduction of the second roller 6 enhances the versatility and flexibility of the upper clamping mechanism. Since the second roller 6 can adjust its position and pressure relatively independently of the first roller 5, the upper clamping mechanism can better adapt to grafting clips 7 of different sizes and shapes, thus enabling the upper clamping mechanism to be widely used in various vegetable grafting operations and improving its application value.

[0047] It should be noted that the design of the second roller 6 can also be further adjusted and optimized according to actual needs. For example, the material, size, shape, and other parameters of the second roller 6 can be adjusted to adapt to the characteristics and transportation requirements of different grafting clamps 7. At the same time, the transportation effect and accuracy of the upper clamping mechanism can be optimized by adjusting the relative position and angle between the second roller 6 and the first roller 5.

[0048] As shown in Figure 3, preferably, in this embodiment, the guide rail 2 is slidably mounted on the frame 1, and the guide rail 2 can slide in a direction perpendicular to the axis of the first roller 5 to adjust its position. Thus, in practical applications, the sliding design of the guide rail 2 allows operators to flexibly adjust its position according to the size, shape, and transportation requirements of the grafting clamp 7, easily adapting to grafting clamps 7 of different sizes and shapes without needing to replace or adjust other components, ensuring that the upper clamping mechanism can stably and efficiently clamp and transport the grafting clamp 7. Furthermore, the sliding design of the guide rail 2 improves the stability and reliability of the upper clamping mechanism. By precisely adjusting the position of the guide rail 2, it can be ensured that the clamping force of the first roller 5 and the second roller 6 on the grafting clamp 7 is uniform and moderate, avoiding transportation problems caused by unstable clamping. In addition, the sliding design of the guide rail 2 simplifies the operation process; operators only need to adjust the position of the guide rail 2 with a simple sliding action, without the need for complex disassembly and installation work. This not only saves time and effort but also reduces the difficulty and cost of operation.

[0049] It should be noted that the sliding design of guide rail 2 can also be combined with other innovative technologies to further improve the performance of the upper clamping mechanism. For example, sensors and automatic control systems can be introduced to monitor and adjust the position of guide rail 2 in real time, achieving more precise and intelligent automated operation. At the same time, the sliding mechanism of guide rail 2 can be optimized to improve its sliding smoothness and durability.

[0050] As shown in Figures 3, 4, and 5, specifically in this embodiment, the upper clamping mechanism further includes a feeding section 9, which is disposed on the frame 1; the guide rail 2 includes a first rail section 21 and a second rail section 22 spaced apart, both the first rail section 21 and the second rail section 22 are provided with the aforementioned transport groove 23, the grafting clamp 7 passes through the transport groove 23 of the first rail section 21 and the second rail section 22 in sequence, the first roller 5 is located between the first rail section 21 and the second rail section 22, the first rail section 21 is relatively close to the feeding section 9 and relatively far away from the dividing component 3, and the second rail section 22 is relatively close to the dividing component 3 and relatively far away from the feeding section 9. Thus, the feeding section 9 serves as the entry point for the grafting clamp 7 to enter the first rail section 21, enabling the grafting clamp 7 to enter the first rail section 21 and the second rail section 22 in an orderly and stable manner, providing strong support for subsequent clamping and transportation. More importantly, the spacing between the first rail section 21 and the second rail section 22 also fully considers the size and shape of the grafting clamp 7, avoiding space waste caused by single-rail transportation, ensuring maximum space utilization, and making the upper clamping mechanism more compact overall.

[0051] As shown in Figures 3, 4, 5 and 7, specifically in this embodiment, the dividing component 3 includes a third driving member 32 and a dividing blade 31. The third driving member 32 and the dividing blade 31 are connected by a transmission. The third driving member 32 can drive the dividing blade 31 to reciprocate. The second track 22 is also provided with a clearance groove 221 to avoid the dividing blade 31. The clearance groove 221 and the transport groove 23 partially overlap.

[0052] As shown in Figures 1, 2, and 3, specifically in this embodiment, the upper clamping mechanism further includes a horizontally arranged operating platform 8 and a first driving member 10. The operating platform 8 provides a stable and easy-to-operate platform for grafting operations. The operating platform 8 has an operating opening 81, which is a specific area on the operating platform 8 for the entry and exit of the grafting clamp 71 and the placement of the scion and rootstock, ensuring the smooth progress of the grafting process. The first driving member 10 is connected to the clamp 4 through a transmission. The first driving member 10 can precisely control the clamp 4 to switch between the clamping state and the open state, and drive the clamp 4 to move up and down between the first position and the second position.

[0053] As shown in Figures 1, 3 and 4, when the gripper 4 is switched to the open state and moved to the first position, the end of the gripper 4 is opposite to the end of the guide rail 2, thus allowing the grafting clip 71 to enter the gripper 4. At this time, the grafting clip 71 is in the clamped state.

[0054] As shown in Figure 2, when the clamp 4 switches to the clamping state and moves to the second position, the clamp 4 opens the grafting clamp 71 to prepare for the placement of the scion and rootstock. The clamp 4 extends beyond the operating opening 81. This action is to ensure that the grafting clamp 71 can be fully exposed in the operating area, so that the operator can accurately place the scion and rootstock into the grafting clamp 71. After the scion and rootstock enter the grafting clamp 71, the clamp 4 can switch back to the open state to release the clamping force on the grafting clamp 71. After the clamping force of the clamp 4 is released, the grafting clamp 71 automatically clamps, tightly joining the scion and rootstock together to complete the grafting work.

[0055] Thus, on the one hand, the precise control of the first driving component 10 enables the automated operation of the gripper 4 mechanism, greatly improving the efficiency and accuracy of grafting operations; on the other hand, the design of the operating table 8 and the operating port 81 makes the grafting process intuitive and easy to understand, reducing the difficulty of operation; furthermore, the gripper 4 mechanism can freely switch between the clamping state and the open state, and can move between different positions, thereby adapting to the grafting needs of grafting clamps 71 of different sizes and shapes as well as different varieties of vegetables; and finally, the overall structural design is reasonable, ensuring the stability and reliability of the grafting process and avoiding grafting failure due to operational errors.

[0056] As shown in Figures 1, 2, and 3, preferably, in this embodiment, the operating port 81 and the first driving component 10 are staggered, with the projection of the first driving component 10 onto the operating table 8 located outside the operating port 81. This layout avoids direct spatial overlap between the two. During the grafting operation, even if debris or fragments splash from the operating port 81, they will not fall directly into the first driving component 10, effectively preventing equipment malfunctions or safety risks caused by debris interference. Thus, on the one hand, the staggered layout reduces the chance of direct contact between debris and the first driving component 10, lowering the risk of equipment damage or personal injury caused by debris interference; on the other hand, it avoids mechanical malfunctions or jamming that may be caused by debris falling into the first driving component 10, ensuring the stability and reliability of the upper clamping mechanism during the grafting operation; furthermore, the optimized layout makes daily cleaning and maintenance of the equipment more convenient, reducing maintenance costs and time; and finally, by reducing downtime caused by equipment malfunctions, the optimized upper clamping mechanism can complete the grafting operation more efficiently, improving production efficiency.

[0057] Specifically, in this embodiment, the gripper 4 includes a first gripping finger 41 and a second gripping finger 42 disposed opposite to each other. Both the first gripping finger 41 and the second gripping finger 42 are transmittedly connected to the first driving member 10. The first driving member 10 can drive the first gripping finger 41 and the second gripping finger 42 to move away from each other so that the gripper 4 switches to an open state. The first driving member 10 can also drive the first gripping finger 41 and the second gripping finger 42 to move closer to each other so that the gripper 4 switches to a clamping state. More specifically, in this embodiment, the first driving member 10 can also drive the first gripping finger 41 and the second gripping finger 42 to move up and down synchronously so that the gripper 4 moves between a first position and a second position.

[0058] It should be noted that in some other embodiments, the gripper 4 may also be, but is not limited to, a pulley gripper, a slide table gripper, or a magnetic gripper, etc., and can be selected according to actual needs, without being limited to one.

[0059] Specifically, in this embodiment, the first driving member 10 and the third driving member 32 are cylinders, and the second driving member 20 is a motor.

[0060] As shown in Figures 1, 2 and 3, this embodiment also provides a grafting device, which includes the upper clamping mechanism as described above, and also includes a seedling cutting mechanism 30, a control module and a foot switch. The seedling cutting mechanism 30 is used to cut the seedling into scions and rootstocks respectively.

[0061] The cutting mechanism 30, the step switch, the first drive component 10 and the second drive component 20 are all electrically connected to the control module. After the control module is powered on, the upper clamping mechanism is started. At this time, the first drive component 10, the second drive component 20, and the third drive component 32 are all started. A part of the grafting material clamp 7 is cut off by the dividing component 3 to form the grafting clamp 71. The second drive component 20 drives the first roller 5 to rotate so that the grafting clamp 71 enters the clamping claw 4. The first drive component 10 drives the clamping claw 4 to switch to the clamping state and move from the first position to the second position. At this time, the clamping claw 4 opens to prepare for the placement of the scion and rootstock.

[0062] When the operator steps on the foot switch, the seedling cutting mechanism 30 works and cuts the seedling into scions and rootstocks. After the operator places the scions and rootstocks into the grafting clamp 71, they can release the foot switch. The first drive component 10 drives the clamp 4 to switch to the open state and move from the second position to the first position. At this time, the clamp 4 clamps again to join the scion and rootstock together, completing the grafting work. After one grafting is completed, a part of the grafting material clamp 7 is cut off by the dividing component 3 to form the grafting clamp 71. The second drive component 20 drives the first roller 5 to rotate so that the grafting clamp 71 enters the clamp 4. The first drive component 10 drives the clamp 4 to switch to the clamping state and move from the first position to the second position. At this time, the clamp 4 opens to prepare for the placement of the scion and rootstock. This is how the grafting operation is carried out.

[0063] In addition, this embodiment also provides a grafting system, including the grafting device as described above, and a grafting clip 7. A portion of the grafting clip 7 can be divided by the dividing component 3 to form a grafting clip 71. The grafting clip 71 includes a clamping post 713, a first clamping leg 711 and a second clamping leg 712. The clamping post 713 is connected between the first clamping leg 711 and the second clamping leg 712. The cross-section of the clamping post 713 perpendicular to the axial direction is circular.

[0064] Example 2

[0065] This embodiment also provides a grafting system, including the grafting device as described in Embodiment 1, and a grafting clip 7. A portion of the grafting clip 7 can be divided by the dividing component 3 to form a grafting clip 71. The grafting clip 71 includes a clamping post 713, a first clamping leg 711 and a second clamping leg 712, and the clamping post 713 is connected between the first clamping leg 711 and the second clamping leg 712.

[0066] As shown in Figure 11, the main difference between this embodiment and Embodiment 1 is that the cross-section of the clamping column 713 perpendicular to the axial direction is elliptical. In this way, the grafting system can be more suitable for grafting melons. It can be understood that melon seedlings are relatively tender. If the cross-section of the clamping column 713 perpendicular to the axial direction is circular, it will be wrapped by the clamping column 713, and the melon seedling is prone to dying. By setting the cross-section of the clamping column 713 perpendicular to the axial direction to a flatter elliptical shape, the contact area between the clamping column 713 and the melon seedling can be reduced, thereby making the grafted melon seedling more likely to survive.

[0067] Example 3

[0068] This embodiment also provides a grafting system, including the grafting device as described in Embodiment 1, and a grafting clip 7. A portion of the grafting clip 7 can be divided by the dividing component 3 to form a grafting clip 71. The grafting clip 71 includes a clamping post 713, a first clamping leg 711 and a second clamping leg 712, and the clamping post 713 is connected between the first clamping leg 711 and the second clamping leg 712.

[0069] As shown in Figure 12, the main difference between this embodiment and Embodiment 1 is that the cross-section of the clamping column 713 perpendicular to the axial direction is teardrop-shaped. In this way, the grafting system can be more suitable for grafting melons. It can be understood that melon seedlings are relatively tender. If the cross-section of the clamping column 713 perpendicular to the axial direction is circular, it will be wrapped by the clamping column 713, and the melon seedling is prone to dying. By setting the cross-section of the clamping column 713 perpendicular to the axial direction to a flatter teardrop shape, the contact area between the clamping column 713 and the melon seedling can be reduced, thereby making the grafted melon seedling more likely to survive.

[0070] Example 4

[0071] This embodiment also provides a grafting system, including the grafting device as described in Embodiment 1, and a grafting clip 7. A portion of the grafting clip 7 can be divided by the dividing component 3 to form a grafting clip 71. The grafting clip 71 includes a clamping post 713, a first clamping leg 711 and a second clamping leg 712, and the clamping post 713 is connected between the first clamping leg 711 and the second clamping leg 712.

[0072] As shown in Figure 13, the main difference between this embodiment and Embodiment 1 is that the cross-section of the clamping column 713 perpendicular to the axial direction is U-shaped. In this way, the grafting system can be more suitable for grafting melons. It can be understood that melon seedlings are relatively tender. If the cross-section of the clamping column 713 perpendicular to the axial direction is circular, it will be wrapped by the clamping column 713, and the melon seedling is prone to dying. By setting the cross-section of the clamping column 713 perpendicular to the axial direction to a flatter U-shape, the contact area between the clamping column 713 and the melon seedling can be reduced, thereby making the grafted melon seedling more likely to survive.

[0073] In summary, the upper clamping mechanism, grafting device, and grafting system disclosed in this application can bring at least the following beneficial technical effects:

[0074] 1) Using the first roller 5 to transport the grafting clip 7 can also improve the continuity and stability of transportation, thereby allowing the transport of grafting clips 7 with a longer length, further improving the grafting efficiency. The overall structure of the upper clip mechanism is also relatively simple and compact, occupies less space, and has a lower production cost, which is conducive to the widespread application of grafting devices.

[0075] 2) The first roller 5 exhibits a specific shape change in the cross section perpendicular to the axis direction. Due to the gradual change in the cross section, it helps the first roller 5 to have better contact with the grafting clamp 7. The first roller 5 can apply pressure to the grafting clamp 7 more evenly during the rolling process, thereby avoiding the problem of unstable transportation caused by uneven pressure.

[0076] 3) The transport trough 23 can more effectively adapt to the transport needs of the grafting clip 7, especially when handling grafting clips 7 of different sizes and shapes. In addition, the figure-eight structure of the transport trough 23 also has a certain guiding function. During the rolling of the first roller 5, it can guide the grafting clip 7 to move along the set direction, avoiding transport problems caused by path deviation.

[0077] 4) The second roller 6 and the first roller 5 can respectively form effective pressure on both sides of the grafting clip 7. In practical applications, when the grafting clip 7 is fed into the upper clamping mechanism, the first roller 5 and the second roller 6 will apply pressure to it at the same time, thereby ensuring that the grafting clip 7 remains stable during transportation.

[0078] The technical means disclosed in this application are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
