[0002] To maintain certain desirable plant traits, specific methods must be employed to pass them on. Currently, due to the increasing prevalence of continuous melon cropping, grafting technology is gaining increasing attention. This has led to the emergence of specialized seedling growers and companies.

[0003] Grafting is a method of artificial vegetative plant propagation in which a branch or bud of one plant is grafted onto the stem or root of another, allowing the two parts to grow into a complete plant. The grafted branch or bud is called the scion, and the grafted stem or root is called the rootstock. The scion is typically a seedling with two to four buds, which becomes the upper part or top of the plant after grafting. The rootstock becomes the root system of the plant after grafting.

[0004] During the grafting process, plants need to be cut to form scions. Cutting the scion is a crucial step in determining the success rate of grafting. Professional seedling growers and nursery companies often perform this process manually. Due to human factors, the cross-section of the scion varies significantly, making it difficult to guarantee the success rate of grafting. Furthermore, the cutting process can easily lead to safety hazards such as scratches. Therefore, a scion cutting device is urgently needed. Utility Model Content

[0027] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0028] According to one aspect of the present invention, a scion cutting device is provided. The scion cutting device can be used to cut a plant to form a scion. The scion can be inserted into the grafting seam of the grafting end of the rootstock, so that a grafted plant can be formed with the rootstock. Therefore, the scion cutting device can provide a basis for subsequent grafting procedures. The scion cutting device can be applied to any suitable equipment, including but not limited to grafting equipment. Therefore, according to another aspect of the present invention, a grafting equipment is also provided. The scion cutting device and the grafting equipment of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-6 As shown, the scion cutting device 100 may include a scion clamping assembly 200 , a cutter assembly 300 and a cutter pushing assembly 400 .

[0030] The scion clamping assembly 200 may include a clamping jaw 210. The clamping jaw 210 may be used to clamp the plant 500. Specifically, the clamping jaw 210 may be opened, the plant 500 may be clamped onto the clamping jaw 210, and then the clamping jaw 210 may be closed to clamp and secure the plant 500. The number of clamping jaws 210 may be any number, such as one, two, or more. In embodiments where a plurality of clamping jaws 210 are provided, the plurality of clamping jaws 210 may be arranged along the extension direction of the plant 500 to clamp different positions of the plant 500.

[0031] The cutter assembly 300 can be located on one side of the clamping jaws 210 along the extension direction of the plant 500. The cutter assembly 300 can be used to cut the plant 500 so that the plant portion clamped by the clamping jaws 210 forms a scion 510. After the cutter assembly 300 cuts the plant 500, the non-scion portion 520 not clamped by the clamping jaws 210 can be discharged. In other words, the cutter assembly 300 can divide the plant 500 into two, forming a scion 510 and a non-scion portion 520, respectively. After the cutter assembly 300 cuts the plant 500, a scion section is formed on the scion 510. When the scion 510 is inserted into the grafting seam of the grafting end of the stock, the scion 510 and the stock can grow into a complete grafted plant through the scion section. The cutter assembly 300 can include any suitable type of cutter assembly, such as a linear cutter assembly or a V-shaped cutter assembly, as long as it can be used to cut the plant 500.

[0032] The driving end of the cutter push assembly 400 can be connected to the cutter assembly 300. The cutter push assembly 400 can drive the cutter assembly 300 to move to cut the plant 500. The cutter push assembly 400 includes but is not limited to a cylinder push assembly, a motor push assembly, or a hydraulic cylinder push assembly, as long as it can achieve the above functions.

[0033] In actual use, the scion cutting device 100 can hold the plant 500 with the jaws 210. During the cutting process of the plant 500, the jaws 210 can prevent the scion 510 from shifting, thereby improving the consistency of the scion's cross-section and enhancing the quality of the scion 510. The cutter pusher assembly 400 can drive the cutter assembly 300 to move, thereby cutting the plant 500. In this way, the portion of the plant 500 held by the jaws 210 can form the scion 510. Since plants are generally not very rigid, the further away from the jaws 210 the plant 500 is, the less rigid it becomes. Therefore, the cutter assembly 300 can be positioned as close to one side of the jaws 210 as possible. This ensures that the plant 500 is held by the jaws 210 at this location, making it less likely to shift and improving the quality of the scion 510. Furthermore, the cutter assembly 300 is less likely to damage the plant 500 during the cutting process, thereby preventing the scion 510 from forming. After the scion 510 is formed, the cutter pushing assembly 400 can drive the cutter assembly 300 back to the initial position, so as to be ready for the next cutting.

[0034] In summary, the scion cutting device 100 provided by the embodiments of the present invention can automatically cut the scion, thus eliminating the need for manual operation. Thus, the scion cutting device 100 can avoid labor costs and prevent safety accidents such as scratches. Furthermore, since there is no human influence, the consistency of the scion cross section is high, thereby improving the quality of the scion and, in turn, the success rate of the grafting. Furthermore, the scion cutting process is highly efficient, thereby improving the efficiency of the grafting process.

[0035] For example, the clamping jaw 210 may include a first clamping jaw 211 and a second clamping jaw 212. Along the extension direction of the plant 500, the first clamping jaw 211 may be located between the cutter assembly 300 and the second clamping jaw 212. The first clamping jaw 211 may be used to clamp a portion of the plant 500 that is close to the cutter assembly 300. The second clamping jaw 212 may be used to clamp a portion of the plant 500 that is away from the cutter assembly 300. The first clamping jaw 211 and the second clamping jaw 212 may clamp the plant 500 at different positions, thereby improving the effectiveness of securing the plant 500 and further preventing the plant 500 from shifting, thereby further improving the consistency of the scion cross section. Since plants are generally not very rigid, clamping the plant at different positions is particularly important.

[0036] For example, the first clamp 211 can be a Y-shaped pneumatic clamp. The Y-shaped pneumatic clamp can include a 30-degree pneumatic clamp or a pneumatic clamp with any other suitable angle. The second clamp 212 can be a parallel pneumatic clamp. In this way, the first clamp 211 and the second clamp 212 can clamp the plant 500 in different directions, thereby further improving the effectiveness of securing the plant 500. Furthermore, if a gas leak occurs, the gas will not contaminate the plant 500, thereby improving the reliability of the scion 510.

[0037] Exemplarily, the scion clamping assembly 200 may further include a dust shield 230. The outer side of the jaw 210 may be used to clamp the plant 500. Of course, the plant 500 may also be clamped from other directions of the jaw 210, such as above the jaw 210. That is, the plant 500 may be clamped to the jaw 210 from the outside, and when the cutting is completed, the scion 510 may also be removed from the outside. The dust shield 230 may be located on the inner side of the jaw 210. The dust shield 230 may prevent dirt on the plant 500 and debris such as dust in the environment in which the scion cutting device 100 is used from entering the jaw 210, thereby increasing the service life of the jaw 210.

[0038] Illustratively, the cutter push assembly 400 may include a push drive 410, a floating joint 420, a linear guide 430, and a slider 440. The slider 440 may be disposed on the cutter assembly 300. The slider 440 may be slidably connected to the linear guide 430. The floating joint 420 may be connected between the driving end of the push drive 410 and the slider 440. Driven by the push drive 410, the slider 440 may slide along the linear guide 430. Specifically, the push drive 410 may drive the slider 440 to slide along the linear guide 430 via the floating joint 420. The slider 440 may drive the cutter assembly 300 to move, thereby enabling the cutter assembly 300 to be cut. The push drive 410 may include, but is not limited to, a pneumatic cylinder, a motor, or a hydraulic cylinder. During the process of cutting the plant 500, the cutter assembly 300 may experience a certain amount of vibration and deformation. The floating joint 420 may eliminate this vibration and deformation, thereby preventing damage to the push drive 410. Furthermore, the linear guide rail 430 can improve the stability and linearity of the movement of the cutter assembly 300, thereby improving the quality of the scion cross section.

[0039] Exemplarily, the scion cutting device 100 may further include an adjusting member 600. The adjusting member 600 may be used to adjust the position of the cutter assembly 300. The adjusting member 600 may be connected between the driving end of the cutter push assembly 400 and the cutter assembly 300. The position of the cutter assembly 300 relative to the adjusting member 600 along the extension direction of the plant 500 is adjustable. In this way, along the extension direction of the plant 500, the cutter assembly 300 can adjust its position relative to the clamping jaw 210, so that the position of the scion section can be selected as required, and installation errors can also be compensated. The structure of the adjustable position of the cutter assembly 300 relative to the adjusting member 600 can be arbitrary. In some embodiments, a waist hole may be provided on the adjusting member 600. The cutter assembly 300 can be connected to different positions of the waist hole through a connecting member, so that its position can be adjusted.

[0040] Exemplarily, the cutter assembly 300 may include a V-shaped cutter 310, a first cutter fixing member 320, a second cutter fixing member 330, an elastic member 340, and a fastener 350. Along the extension direction of the plant 500, the V-shaped cutter 310 may be tapered away from the clamping jaw 210. The V-shaped cutter 310 may be used to cut the plant 500 so that the plant part clamped by the clamping jaw 210 forms a scion 510. In this way, the cross section of the scion may be a V-shaped cross section. The V-shaped cross section has a larger area, which is conducive to improving the success rate of grafting. In addition, the tip of the V-shaped cross section can be easily inserted into the grafting seam of the grafting end of the rootstock. A V-shaped groove 321 may be provided on the first cutter fixing member 320. A V-shaped boss 331 may be provided on the second cutter fixing member 330. The fastener 350 can be connected between the first cutter fixing member 320 and the second cutter fixing member 330 so that the V-shaped groove 321 and the V-shaped boss 331 can clamp the V-shaped cutter 310. In addition, the elastic member 340 can be squeezed between the first cutter fixing member 320 and the second cutter fixing member 330. The elastic member 340 includes but is not limited to a spring or an elastic member made of an elastic material such as rubber. When the V-shaped cutter 310 needs to be replaced due to wear, the fastener 350 needs to be removed. The elastic member 340 can then release its elastic potential energy, thereby causing the first cutter fixing member 320 and the second cutter fixing member 330 to be ejected, allowing the V-shaped cutter 310 to be quickly removed and replaced. Therefore, the cutter assembly 300 can improve the efficiency of cutter replacement, thereby improving the efficiency of grafting work.

[0041] For example, the first cutter fixing member 320 may be provided with a through hole 322 and a threaded hole 323. The through hole 322 and the threaded hole 323 may be coaxial and located on either side of the V-shaped cutter 310. A fastener 350 may pass through the through hole 322 and the second cutter fixing member 330 and may be threadedly connected to the threaded hole 323. The fastener 350 includes, but is not limited to, a screw or a bolt. This facilitates installation and removal of the fastener 350, resulting in a simpler structure for the cutter assembly 300.

[0042] Exemplarily, the cutter assembly 300 may further include a cutter guard 360. The cutter guard 360 may be connected to the first cutter fixing member 320. The cutter guard 360 may cover the V-shaped cutter 310. Furthermore, the cutter guard 360 may have an opening 361 that exposes the V-shaped cutter 310. In this way, when the cutter push assembly 400 drives the cutter assembly 300 to move, the plant 500 may pass through the opening 361 and be cut by the V-shaped cutter 310. The cutter guard 360 may protect the V-shaped cutter 310, thereby preventing people from accidentally touching the V-shaped cutter 310 and getting injured.

[0043] Exemplarily, the cutter guard cover 360 may include a pair of guard plates 370. The pair of guard plates 370 may be located on both sides of the V-shaped cutter 310. Each of the pair of guard plates 370 may include a connecting portion 371 and a covering portion 372. One end of the connecting portion 371 of the pair of guard plates 370 may be connected to both sides of the first cutter fixing member 320, respectively. The other end of the connecting portion 371 of the pair of guard plates 370 may extend outside the V-shaped cutter 310. One end of the covering portion 372 of the pair of guard plates 370 may be connected to its corresponding connecting portion 371, respectively. The other end of the covering portion 372 of the pair of guard plates 370 may extend toward each other at a predetermined distance to form an opening 361. In this way, each of the pair of guard plates 370 may be generally L-shaped. With such an arrangement, the structure of the cutter guard cover 360 is relatively simple and convenient for processing and manufacturing.
