[0038] Embodiment one

[0039] Please refer to Figures 1 to 8The embodiment discloses an upper clamping mechanism; the upper clamping mechanism comprises a rack 1, a guide rail 2, a segmentation assembly 3, a clamping jaw 4 and a first roller 5; the guide rail 2 is arranged on the rack 1 and is used for conveying a long strip-shaped grafting material clamp 7; the segmentation assembly 3 is used for cutting a part of the grafting material clamp 7 to form a grafting clamp 71; the clamping jaw 4 can be switched between a clamping state and an open state, the clamping jaw 4 can open the grafting clamp 71 when being switched to the clamping state, and the clamping jaw 4 can allow the grafting clamp 71 to enter the clamping jaw 4 or release the clamping of the grafting clamp 71 to make the grafting clamp 71 clamped when being switched to the open state; and the first roller 5 is rotatably arranged on the rack 1, wherein the first roller 5 is used for contacting the grafting material clamp 7 to make the grafting material clamp 7 move along the guide rail 2, so that the grafting clamp 71 is pushed into the clamping jaw 4 switched to the open state.

[0040] The upper clamping mechanism provided by the embodiment is used for placing the grafting material clamp 7 on the guide rail 2, and the segmentation assembly 3 can cut a part of the grafting material clamp 7 as the grafting clamp 71; when upper clamping is needed, the clamping jaw 4 can be switched to the open state first, the first roller 5 is rotated to push the grafting material clamp 7 to move along the guide rail 2, the grafting material clamp 7 pushes the cut grafting clamp 71 into the clamping jaw 4, at this time, the grafting clamp 71 is in the clamped state, then the clamping jaw 4 can be switched to the clamping state to open the grafting clamp 71, after the grafting clamp 71 is filled with the scion and the stock, the clamping jaw 4 is switched to the open state again to make the grafting clamp 71 clamped again, and the grafting process (the scion and the stock are combined together) can be completed, the operation is simple and convenient and relatively accurate, the grafting effect is good, the skill requirement and the labor intensity of the operator are reduced, the first roller 5 is used for conveying the grafting material clamp 7, the continuity and the stability of conveying can be improved, the grafting material clamp 7 with a relatively long length can be conveyed, the grafting efficiency is further improved, the overall structure of the upper clamping mechanism is relatively simple and compact, the space occupied is relatively small, the production cost is relatively low, and the upper clamping mechanism is favorable for the wide application of the grafting device.

[0041] As shown in Figure 4 , specifically, in the embodiment, the upper clamping mechanism further comprises a second driving member 20, the second driving member 20 is arranged on the rack 1, the second driving member 20 is in transmission connection with the first roller 5 and is used for driving the first roller 5 to rotate.

[0042] As shown in Figure 4 , Figure 5 and Figure 8As shown, preferably, in the present embodiment, the first roller 5 comprises a first taper portion 51 and a second taper portion 52 connected in series, which are respectively used to contact the two sides of the grafting material clamp 7 arranged at an angle; the first taper portion 51 gradually decreases in the direction away from the second taper portion 52 in the cross section perpendicular to the axis direction; the second taper portion 52 gradually decreases in the direction away from the first taper portion 51 in the cross section perpendicular to the axis direction. In this way, this design makes the first roller 5 present a specific shape change in the cross section perpendicular to the axis direction, due to the gradual change of the cross section, which helps the first roller 5 to better contact the grafting material clamp 7, and the first roller 5 can more evenly apply pressure to the grafting material clamp 7 during rolling, thereby avoiding the problem of unstable transportation caused by uneven pressure, and further enabling the first roller 5 to more effectively push the grafting material clamp 7 to move along the guide rail 2, improving the continuity and stability of transportation, prolonging the service life of the first roller 5, and reducing maintenance costs.

[0043] As shown in the drawings, Figure 8 Preferably, in the present embodiment, in order to enhance the friction between the first roller 5 and the grafting material clamp 7, the circumferential wall of the first taper portion 51 is provided with a plurality of first grooves 511 arranged at intervals, and the circumferential wall of the second taper portion 52 is provided with a plurality of second grooves 521 arranged at intervals; in this way, the design of these grooves not only increases the roughness of the surface 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 material 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 material clamps 7 of different materials and thicknesses.

[0044] It should be noted that the groove design of the first taper portion 51 and the second taper portion 52 can be adjusted in terms of quantity, depth and interval 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, and adjusting the interval of the grooves can optimize the rolling effect of the roller.

[0045] As shown in the drawings, Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, preferably, in the present embodiment, the guide rail 2 is provided with a transportation groove 23, which includes a first inclined groove 231 and a second inclined groove 232 that are connected and jointly form a spade structure, and a groove opening 233 that is connected to the intersection of the first inclined groove 231 and the second inclined groove 232; in this way, the transportation groove 23 can more effectively adapt to the transportation needs of the grafting material clamp 7, especially when handling grafting material clamps 7 of different sizes and shapes, and in addition, the transportation groove 23 with a spade structure also has a certain guiding effect, which can guide the grafting material clamp 7 to move in a set direction during the rolling process of the first roller 5, avoiding transportation problems caused by path deviation. This guiding effect not only improves the accuracy of grafting operations, but also reduces errors and waste caused by improper operation.

[0046] It should be noted that the design of the transportation groove 23 can be further adjusted and optimized according to actual needs. For example, the inclination angle of the first inclined groove 231 and the second inclined groove 232, the size and shape of the groove opening 233, and other parameters can be adjusted to adapt to the specific requirements of different grafting operations, and by optimizing these parameters, we can further improve the transportation efficiency and adaptability of the guide rail 2.

[0047] As shown in Figure 3 , Figure 4 and Figure 5 , preferably, in the present embodiment, the upper clamping mechanism further includes a second roller 6, which is rotatably arranged on the rack 1, and the second roller 6 and the first roller 5 are oppositely arranged, and the second roller 6 and the first roller 5 are respectively used to form pressure on both sides of the grafting material clamp 7. In this way, this layout allows the second roller 6 and the first roller 5 to effectively press on both sides of the grafting material clamp 7, and in actual application, when the grafting material clamp 7 is fed into the upper clamping mechanism, the first roller 5 and the second roller 6 will simultaneously apply pressure to it, thereby ensuring that the grafting material clamp 7 remains stable during transportation. This design of double-sided pressure not only improves the stability of the transportation of the grafting material clamp 7, but also effectively prevents the grafting material clamp 7 from deviating or slipping during transportation; in addition, the introduction of the second roller 6 also enhances the versatility and flexibility of the upper clamping mechanism, as the second roller 6 can be independently adjusted in position and pressure relative to the first roller 5, the upper clamping mechanism can better adapt to grafting material clamps 7 of different sizes and shapes, thereby allowing the upper clamping mechanism to be widely used in various vegetable grafting operations, improving its application value.

[0048] 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 needs of different grafting material clamps 7. At the same time, the relative position and angle between the second roller 6 and the first roller 5 can also be adjusted to optimize the transportation effect and accuracy of the clamping mechanism.

[0049] As shown in Figure 3 , preferably, in this embodiment, the guide rail 2 is slidingly arranged on the rack 1, and the guide rail 2 can slide in a direction perpendicular to the axis of the first roller 5 to adjust the position. In this way, in actual application, the sliding design of the guide rail 2 allows the operator to flexibly adjust the position of the guide rail 2 according to the size, shape and transportation needs of the grafting material clamp 7, and can easily adapt to grafting material clamps 7 of different sizes and shapes without the need to replace or adjust other components to ensure that the clamping mechanism can stably and efficiently clamp and transport the grafting material clamp 7; and the sliding design of the guide rail 2 improves the stability and reliability of the clamping mechanism, and by precisely adjusting the position of the guide rail 2, it can ensure that the clamping force of the first roller 5 and the second roller 6 on the grafting material clamp 7 is uniform and moderate, avoiding transportation problems caused by unstable clamping; in addition, the sliding design of the guide rail 2 also simplifies the operation process, and the operator only needs to adjust the position of the guide rail 2 through a simple sliding action, without the need for complex disassembly and installation work, which not only saves time and effort, but also reduces the operation difficulty and cost.

[0050] It should be noted that the sliding design of the guide rail 2 can also be combined with other innovative technologies to further improve the performance of the clamping mechanism. For example, sensors and automatic control systems can be introduced to monitor and adjust the position of the guide rail 2 in real time, achieving more accurate and intelligent automated operation, and the sliding mechanism of the guide rail 2 can also be optimized to improve its sliding stability and durability.

[0051] As shown in Figure 3 , Figure 4 , and Figure 5As shown, specifically, in the present embodiment, the upper clamping mechanism further comprises a feeding part 9, which is arranged on the frame 1; the guide rail 2 comprises a first rail part 21 and a second rail part 22 arranged at intervals, both of which are provided with the transport groove 23 described above, the grafting clamp 7 sequentially passes through the transport grooves 23 of the first rail part 21 and the second rail part 22, the first roller 5 is located between the first rail part 21 and the second rail part 22, the first rail part 21 is relatively close to the feeding part 9 and relatively far from the dividing assembly 3, and the second rail part 22 is relatively close to the dividing assembly 3 and relatively far from the feeding part 9. In this way, the feeding part 9 serves as the entrance of the grafting clamp 7 into the first rail part 21, so that the grafting clamp 7 can enter the first rail part 21 and the second rail part 22 in an orderly and stable manner, thereby providing a strong guarantee for subsequent clamping and transportation; more importantly, the interval arrangement of the first rail part 21 and the second rail part 22 also fully considers the size and shape of the grafting clamp 7, avoids the waste of space caused by single-rail transportation, ensures the maximization of space utilization, and thus makes the upper clamping mechanism more compact as a whole.

[0052] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 7 , specifically, in the present embodiment, the dividing assembly 3 comprises a third driving member 32 and a dividing knife 31, the third driving member 32 and the dividing knife 31 are in transmission connection, the third driving member 32 can drive the dividing knife 31 to make reciprocating motion, and the second rail part 22 is further provided with a avoiding groove 221 for avoiding the dividing knife 31, the avoiding groove 221 and the transport groove 23 partially overlap.

[0053] As shown in Figure 1 , Figure 2 and Figure 3 , specifically, in the present embodiment, the upper clamping mechanism further comprises a horizontally arranged operation table 8 and a first driving member 10, the operation table 8 provides a stable and convenient operation platform for grafting operation, the operation table 8 is provided with an operation opening 81, the operation opening 81 is a specific area opened on the operation table 8, which is used for the grafting clamp 71 to enter and exit and for the placement of scions and stock plants, thereby ensuring the smooth progress of the grafting process; the first driving member 10 and the clamping jaw 4 are in transmission connection, the first driving member 10 can accurately control the clamping jaw 4 to switch between the clamping state and the open state, and drive the clamping jaw 4 to move up and down between the first position and the second position.

[0054] As shown in Figure 1 , Figure 3 and Figure 4 , when the clamping jaw 4 is switched to the open state and moves to the first position, the clamping jaw 4 is opposite to the end of the guide rail 2, thereby allowing the grafting clamp 71 to enter the clamping jaw 4, at this time, the grafting clamp 71 is in the clamping state;

[0055] As shown in Figure 2As shown, when the clamping jaw 4 switches to the clamping state and moves to the second position, the clamping jaw 4 opens the grafting clamp 71 to prepare for the placement of the scion and the stock, and the clamping jaw 4 extends out of the operation port 81. This action is to ensure that the grafting clamp 71 is fully exposed in the operation area, so that the operator can accurately place the scion and the stock in the grafting clamp 71. After the scion and the stock enter the grafting clamp 71, the clamping jaw 4 can be switched to the open state again to release the clamping force on the grafting clamp 71. After losing the clamping force of the clamping jaw 4, the grafting clamp 71 automatically clamps tightly to combine the scion and the stock together, and the grafting work is completed.

[0056] In this way, on the one hand, through the precise control of the first driving member 10, the automatic operation of the clamping jaw 4 mechanism is realized, greatly improving the efficiency and accuracy of the grafting operation; on the other hand, the design of the operation table 8 and the operation port 81 makes the grafting process intuitive and easy to understand, reducing the operation difficulty; on the other hand, the clamping jaw 4 mechanism can freely switch between the clamping state and the open state, and can move between different positions, thereby adapting to different sizes and shapes of the grafting clamp 71 and different varieties of vegetable grafting needs; on the other hand, the overall structure design is reasonable, ensuring the stability and reliability of the grafting process, avoiding grafting failure due to operation errors.

[0057] As shown in Figure 1 , Figure 2 and Figure 3 , preferably, in the present embodiment, the operation port 81 and the first driving member 10 are staggered, and the projection of the first driving member 10 to the operation table 8 is located outside the operation port 81. This layout avoids the direct overlap of the two in space. During the grafting operation, even if there are sundries or debris flying in the operation port 81, they will not directly fall into the first driving member 10, thereby effectively avoiding equipment failure or safety risks caused by sundries interference. In this way, on the one hand, the staggered layout design reduces the opportunity of direct contact between sundries and the first driving member 10, reducing the risk of equipment damage or personnel injury caused by sundries interference; on the other hand, it avoids the mechanical failure or jamming phenomenon that may be caused by the falling of sundries into the first driving member 10, ensuring the stability and reliability of the upper clamping mechanism during the grafting operation; on the other hand, the optimized layout makes the daily cleaning and maintenance of the equipment more convenient, reducing the maintenance cost and time; on the other hand, by reducing the downtime caused by equipment failure, the optimized upper clamping mechanism can more efficiently complete the grafting operation, improving the production efficiency.

[0058] Specifically, in the embodiment, the clamping jaw 4 comprises a first clamping finger 41 and a second clamping finger 42 arranged oppositely, and the first clamping finger 41 and the second clamping finger 42 are both in transmission connection with the first driving member 10; the first driving member 10 can drive the first clamping finger 41 and the second clamping finger 42 to move away from each other so as to switch the clamping jaw 4 to the open state; the first driving member 10 can drive the first clamping finger 41 and the second clamping finger 42 to move close to each other so as to switch the clamping jaw 4 to the clamping state; more specifically, in the embodiment, the first driving member 10 can also drive the first clamping finger 41 and the second clamping finger 42 to move up and down synchronously so as to move the clamping jaw 4 between the first position and the second position.

[0059] It should be noted that, in some other embodiments, the clamping jaw 4 can also be, but is not limited to, a pulley gripper or a sliding table clamping jaw or a magnetic clamping jaw, etc., which can be selected according to actual needs, and is not limited herein.

[0060] Specifically, in the embodiment, the first driving member 10 and the third driving member 32 are air cylinders, and the second driving member 20 is a motor.

[0061] As shown in Figure 1 , Figure 2 and Figure 3 , in addition, the embodiment also provides a grafting device, the grafting device comprising the upper clamping mechanism as described above, the grafting device further comprising a cutting seedling mechanism 30, a control module and a foot switch, the cutting seedling mechanism 30 being used for cutting seedlings into scions and stocks respectively;

[0062] The cutting seedling mechanism 30, the foot switch, the first driving member 10 and the second driving member 20 are all in electrical connection with the control module, after the control module is powered on, the upper clamping mechanism is started, at this time, the first driving member 10, the second driving member 20 and the third driving member 32 are all started, a part of the grafting material clamping member 7 is cut off by the dividing assembly 3 to form a grafting clamping member 71, the second driving member 20 drives the first roller 5 to rotate so as to make the grafting clamping member 71 enter the clamping jaw 4, the first driving member 10 drives the clamping jaw 4 to switch to the clamping state and moves from the first position to the second position, at this time, the clamping jaw 4 is opened to prepare for the placement of the scion and the stock;

[0063] 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.

[0064] 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.

[0065] Example 2

[0066] 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.

[0067] like Figure 11 As shown, 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.

[0068] Example 3

[0069] 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.

[0070] As shown in Figure 12 The main difference between this embodiment and embodiment one is that the cross section of the clamping column 713 perpendicular to the axial direction is in the shape of a water droplet, so that the grafting system is more suitable for grafting melons, and it can be understood that the seedlings of melons are relatively tender, if the cross section of the clamping column 713 perpendicular to the axial direction is in the shape of a circle, then it will be wrapped by the clamping column 713, and the seedlings of melons are prone to die, and setting the cross section of the clamping column 713 perpendicular to the axial direction to be a relatively flat water droplet shape can achieve the purpose of reducing the contact area between the clamping column 713 and the seedlings of melons, so that the grafted seedlings of melons are more likely to survive.

[0071] Embodiment four

[0072] This embodiment also provides a grafting system, which comprises the grafting device as described in embodiment one, and further comprises a grafting material clamp 7, a part of the grafting material clamp 7 can be split by the split assembly 3 to form a grafting clamp 71; the grafting clamp 71 comprises a clamping column 713, a first clamping leg 711 and a second clamping leg 712, and the clamping column 713 is connected between the first clamping leg 711 and the second clamping leg 712;

[0073] As shown in Figure 13 The main difference between this embodiment and embodiment one is that the cross section of the clamping column 713 perpendicular to the axial direction is in the shape of a U, so that the grafting system is more suitable for grafting melons, and it can be understood that the seedlings of melons are relatively tender, if the cross section of the clamping column 713 perpendicular to the axial direction is in the shape of a circle, then it will be wrapped by the clamping column 713, and the seedlings of melons are prone to die, and setting the cross section of the clamping column 713 perpendicular to the axial direction to be a relatively flat U shape can achieve the purpose of reducing the contact area between the clamping column 713 and the seedlings of melons, so that the grafted seedlings of melons are more likely to survive.

[0074] In summary, the upper clamping mechanism, the grafting device and the grafting system disclosed by the utility model can at least bring the following beneficial technical effects:

[0075] 1) The use of the first roller 5 to transport the grafting material clamp 7 can also improve the continuity and stability of transportation, thereby allowing the transportation of a grafting material clamp 7 with a relatively long length, further improving the grafting efficiency, and the overall structure of the upper clamping mechanism is also relatively simple and compact, occupies a relatively small space, and has a relatively low production cost, which is conducive to the wide application of the grafting device;

[0076] 2) The first roller 5 presents a specific shape change in the cross section perpendicular to the axial direction, and due to the gradual change of the cross section, it is helpful for better contact between the first roller 5 and the grafting material clamp 7, and the first roller 5 can apply pressure more uniformly to the grafting material clamp 7 during rolling, thereby avoiding the problem of unstable transportation caused by uneven pressure;

[0077] 3) The transport groove 23 can more effectively adapt to the transportation needs of the grafting clamp 7, especially when dealing with different sizes and shapes of grafting clamps 7, and in addition, the transport groove 23 with a splayed structure also has a certain guiding effect, which can guide the grafting clamp 7 to move in a set direction during the rolling process of the first roller 5, avoiding transportation problems caused by path deviation;

[0078] 4) The second roller 6 and the first roller 5 can effectively resist the pressure on both sides of the grafting clamp 7, respectively, in actual application, when the grafting clamp 7 is sent into the upper clamping mechanism, the first roller 5 and the second roller 6 will simultaneously apply pressure to it, thereby ensuring that the grafting clamp 7 remains stable during transportation.

[0079] The technical means disclosed in the utility model scheme is not only limited to the technical means disclosed in the above-mentioned embodiments, but also includes the technical scheme composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
