[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0028] The utility model will be further described in detail below in combination with the drawings.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , the embodiment discloses a cutting mechanism for grafting machine, including support seat 1 and cutter 2;Support seat 1 is provided with transversely extending cutting groove 11, cutting groove 11 is used to place plant body, the extension direction of cutting groove 11 is substantially same with the extension direction of plant body;Cutter 2 can move up and down relative to cutting groove 11, cutter 2 has cutter edge 21, cutter edge 21 is towards cutting groove 11, wherein, the horizontal cross section of cutter 2 is inclined to the extension direction of cutting groove 11 in the horizontal direction. Specifically, in the embodiment, the extension direction of cutting groove 11 can refer to the e1 direction in Figure 3 .

[0030] The cutting mechanism provided by the embodiment has the following advantages. On the one hand, the support seat 1 in the cutting mechanism is provided with a transversely extending cutting groove 11, and the extending direction of the cutting groove 11 is basically the same as the extending direction of the plant body. This design enables the plant body to maintain its natural growth direction when placed, thereby avoiding the problem of vascular bundle damage caused by the inconsistency between the cutting direction and the growth direction of the plant body. On the other hand, the horizontal cross section of the cutter 2 in the horizontal direction is inclined to the extending direction of the cutting groove 11. This inclined design enables the cutter 2 to cut into the plant body in a more gentle and gradual manner, rather than directly perpendicular to the center line of the plant body as in the traditional cutting method, thereby effectively reducing the damage to the vascular bundle of the plant body during the cutting process, and further improving the survival rate of the plant after grafting.

[0031] As shown in Figure 4 and Figure 5 , preferably, in the embodiment, the cutting edge 21 extends in a direction inclined to the horizontal plane. Specifically, the inclined design of the cutting edge 21 enables the cutter 2 to cut into the plant body in a smaller angle and smoother manner, which further reduces the damage to the internal structure of the plant body during the cutting process, especially reduces the impact on important tissues such as vascular bundle. This delicate cutting method helps to preserve the physiological functions of the plant body, improves the survival rate and growth quality of the plant after grafting.

[0032] As shown in Figure 2 and Figure 4 , preferably, in the embodiment, the cutting groove 11 has a V-shaped cross section perpendicular to the extending direction. In this way, on the one hand, the design of the V-shaped cutting groove 11 enables the plant body to fit more closely to the groove wall when placed, reducing the cutting deviation caused by shaking or improper position. At the same time, the two side walls of the V-shaped groove form a certain guiding effect on the plant body, which helps the cutter 2 to move more accurately along the predetermined cutting line, thereby improving the cutting accuracy. On the other hand, the bottom of the V-shaped cutting groove 11 is relatively narrow, so that the cutter 2 can concentrate more force during the cutting process, reducing the energy dispersion during the cutting process. This helps to form a more flat and smooth cutting surface, reduces the problem of unstable grafting interface caused by uneven cutting, and improves the survival rate of the plant after grafting. On the other hand, the design of the V-shaped cutting groove 11 also enhances the support stability of the support seat 1 to the plant body. During the cutting process, the root or stem of the plant body can be more firmly embedded in the V-shaped groove, reducing the impact of the cutting generated vibration or impact force on the plant body, and helping to maintain the overall stability and integrity of the plant body. On the other hand, the width of the opening 51 of the V-shaped cutting groove 11 can be adjusted according to the shape and size of different plant bodies, thereby enhancing the adaptability and flexibility of the cutting mechanism. This design enables the cutting mechanism to be applicable to a wider range of plant species and grafting needs, improving the universality and practicality in agricultural production.

[0033] As Figure 4 shown, preferably, in the present embodiment, the support seat 1 is also provided with an avoidance groove 12, which is in communication with the cutting groove 11. The extension direction of the avoidance groove 12 is the same as the extension direction of the cross section of the cutting knife 2 in the horizontal direction. When the cutting knife 2 moves downward, the cutting knife 2 can be partially inserted into the avoidance groove 12. In this way, the existence of the avoidance groove 12 provides additional space for the cutting knife 2, enabling it to move more smoothly during the cutting process, reducing the cutting resistance caused by friction or obstruction, and thus improving the cutting efficiency and cutting quality. On the other hand, since the avoidance groove 12 has the same extension direction as the cross section of the cutting knife 2, it helps the cutting knife 2 to cut into the plant body at a more ideal angle, further reducing the potential damage to the vascular bundle and improving the success rate of grafting and the survival rate of the plant.

[0034] As Figure 2 and Figure 4 shown, preferably, in the present embodiment, the cutting knife 2 is provided with two, and the support seat 1 is provided with two, with one-to-one correspondence between the two cutting knives 2 and the two support seats 1. One cutting knife 2 is used to cut the plant body to form the scion, and the other cutting knife 2 is used to cut the plant body to form the rootstock. In this way, on the one hand, the two cutting knives 2 are used to cut the plant body to form the scion and the rootstock, respectively. This design allows two key steps to be completed in one operation, significantly shortening the grafting operation time. At the same time, since the two cutting knives 2 work synchronously, the errors and uncertainties caused by multiple operations are also reduced, improving the overall efficiency of the grafting operation. On the other hand, the two cutting knives 2 are consistent in design and manufacture, ensuring that the cutting surfaces produced during the cutting process have similar or identical shapes and sizes, which helps to form a tight and stable interface during grafting, improving the survival rate and growth quality of the plant after grafting. On the other hand, the two support seats 1 are used to support the plant body to be cut, making it easier for the operator to position and fix the plant body, reducing the cutting deviation caused by plant body shaking or improper position.

[0035] As Figure 2 and Figure 4As shown, preferably, in the present embodiment, the cutting mechanism further comprises a driving member 3 and a connecting member 4, the two cutters 2 are respectively arranged at the two ends of the connecting member 4, the driving member 3 and the connecting member 4 are in transmission connection, the driving member 3 drives the connecting member 4 to move up and down, and the two cutters 2 move up and down synchronously under the driving of the connecting member 4. In this way, the design of the connecting member 4 enables the two cutters 2 to move up and down synchronously under the driving of the driving member 3, thereby realizing synchronous cutting of the scion and the stock. This synchronous cutting mode helps to maintain the consistency and flatness of the cutting surface and reduces the problem of unstable grafting interface caused by uneven cutting. Preferably, in the present embodiment, the driving member 3 is a pneumatic cylinder.

[0036] As shown in Figure 1 and Figure 6 As shown, preferably, in the present embodiment, the cutting mechanism further comprises a cover 5, the cover 5 is provided with a containing cavity, the cutters 2, the support seat 1 and the connecting member 4 are all located in the containing cavity, the cover 5 is provided with an opening 51, and the cutting groove 11 is exposed to the opening 51. In this way, the design of the cover 5 contains the key components such as the cutters 2, the support seat 1 and the connecting member 4 in the containing cavity, avoiding the direct contact of the operators with the sharp cutters 2 and the moving components, thereby significantly improving the safety of the operation. At the same time, the cover 5 also prevents the debris and splashes generated during the cutting process from causing harm to the operators and the environment. On the other hand, the cover 5 not only provides safety protection for the operators, but also provides protection for the key components of the cutting mechanism. It prevents the influence of external factors such as dust and moisture on the cutting mechanism, reduces the wear and failure rate of the equipment, and thereby prolongs the service life of the equipment. On the other hand, the design of the cover 5 enables the cutting mechanism to maintain a stable operating state during the operation process. It reduces the shaking or position deviation of the equipment caused by external interference, thereby improving the precision and stability of the cutting operation.

[0037] More preferably, in the present embodiment, the two ends of the connecting member 4 are respectively in sliding fit with the opposite two inner side walls of the containing cavity. In this way, on the one hand, the sliding fit of the two ends of the connecting member 4 with the opposite two inner side walls of the containing cavity ensures the stability of the cutting mechanism during the up and down movement. This fit mode effectively prevents the shaking or deviation of the connecting member 4 during the movement, thereby improving the precision and stability of the cutting operation. On the other hand, the design of the sliding fit reduces the friction and wear between the connecting member 4 and the containing cavity, prolonging the service life of the equipment. At the same time, since the sliding fit can uniformly distribute the stress, it also reduces the risk of equipment damage caused by uneven stress. On the other hand, the stable movement of the connecting member 4 ensures the accurate position of the cutters 2 during the cutting process. This precise control helps to form a flat and uniform cutting surface, reduces the problem of unstable grafting interface caused by cutting deviation, and improves the survival rate and growth quality of the grafted plants.

[0038] As shown in Figure 4As shown, specifically in this embodiment, the cutting mechanism further includes a bracket 7, and the support base 1 and the driving component 3 are both mounted on the bracket 7.

[0039] In addition, this embodiment also provides a grafting machine, including the cutting mechanism described above. This grafting machine has all the advantages of the cutting mechanism described above, which will not be repeated here.

[0040] like Figure 6 As shown, specifically in this embodiment, the grafting machine includes a horizontally arranged upper platform 6, and a cutting mechanism is located at the edge of the upper platform 6. Unwanted plant structures can fall directly from the edge of the upper platform 6. It is understood that during the grafting process, it is often necessary to remove unwanted plant structures (such as excess branches, leaves, etc.). By placing the cutting mechanism at the edge of the upper platform 6, these unwanted structures can fall directly from the edge of the upper platform 6 after cutting. Since the unwanted plant structures can fall directly, the operator does not need to interrupt the operation to clean them up, thus allowing them to focus more on the grafting operation itself. This not only improves operational efficiency but also helps maintain the continuity and stability of the operation.

[0041] In summary, the cutting mechanism and grafting machine including it disclosed in this utility model can bring at least the following beneficial technical effects:

[0042] 1) The support seat 1 in the cutting mechanism is provided with a horizontally extending cutting groove 11. The extension direction of the cutting groove 11 is roughly the same as the extension direction of the plant. This design allows the plant to maintain its natural growth direction when placed, avoiding the problem of vascular bundle damage caused by the inconsistency between the cutting direction and the plant's growth direction.

[0043] 2) The horizontal cross-section of the cutter 2 is inclined to the extension direction of the cutting groove 11. This inclined design allows the cutter 2 to cut into the plant in a gentler and gradual manner when cutting the plant, instead of cutting directly perpendicular to the center line of the plant as in the traditional cutting method. This can effectively reduce the damage to the vascular bundles of the plant during the cutting process, thereby improving the survival rate of the grafted plant.

[0044] 3) The design of the V-shaped cutting groove 11 allows the plant to fit more closely to the groove wall when placed, reducing cutting deviation caused by shaking or improper position. At the same time, the two side walls of the V-shaped groove provide a certain guiding effect for the plant, which helps the cutter 2 to move more accurately along the predetermined cutting line, thereby improving the cutting accuracy.

[0045] 4) The inclined design of the knife edge 21 enables the cutting knife 2 to cut into the plant body at a smaller angle and in a smoother manner, which further reduces the damage to the internal structure of the plant body during cutting, especially reduces the impact on important tissues such as vascular bundles, and this delicate cutting manner helps to retain the physiological function of the plant body, improves the survival rate and growth quality of the grafted plant.

[0046] The technical means disclosed in the utility model scheme are not limited to the technical means disclosed in the above-mentioned embodiments, and also include technical schemes composed of any combination of the above technical features. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the utility model, and these improvements and refinements are also considered to be within the protection scope of the utility model.
