Description

Technical Field

[0001] The present invention relates to the technical field of grafting devices, and in particular to a grafting device for growing melon seedlings and a grafting method thereof. Background Art

[0002] Melon wilt is a worldwide soil-borne fungal disease caused by Fusarium oxysporum, specifically for watermelon and melon. It can survive in the soil for long periods of time, making it difficult to control and causing significant losses to melon production. Currently, the most effective method for combating melon wilt is grafting. Research by domestic and international scholars has shown that melon grafting not only prevents wilt but also increases yield, promotes early maturity, improves plant tolerance to low light levels, salinity, and low temperatures, conserves fertilizer, and is environmentally friendly. Undoubtedly, the vigorous promotion of grafting cultivation technology is of great significance for high-quality and high-yield melons. Melon grafting is an agricultural technique that involves grafting a melon (scion) onto another cucurbit (rootstock) to improve disease resistance, stress tolerance, and yield. Commonly used grafting methods include cutting grafting, stick grafting and approach grafting. The appropriate method is selected based on the affinity between the rootstock and the scion. However, the grafting process may face challenges such as unstable survival rate, changes in fruit quality and high costs.

[0003] The existing melon seedling raising device includes: a grafting clamp and a blade. First, the blade is used to obliquely cut off the growth point and the other cotyledon from the cotyledon of the rootstock, with the incision length of 7 to 10 mm; the cut surfaces of the rootstock and scion are aligned and placed together, and then fixed tightly with a grafting clamp. The grafting clamp clamps the rootstock and scion so that their interface can grow and heal quickly, completing the grafting. However, when a large number of melon seedlings are needed for grafting, individual cutting and grafting fixation affect efficiency and waste time. Summary of the Invention

[0020] The present invention is described below by means of several specific embodiments. To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present invention appears in more than one drawing, the component may be represented by the same reference numeral in each drawing.

Figure 2 A top view of a melon seedling grafting device and a grafting method thereof provided in an embodiment of the present invention. Figure 3 A schematic diagram of the structure of an L-shaped guide rail provided in an embodiment of the present invention. Figure 4 A schematic structural diagram of a grafting and fixing assembly provided in an embodiment of the present invention is shown. Figure 5 This is a schematic structural diagram of a breeding box provided in an embodiment of the present invention.

[0022] like Figure 1 and Figure 3 As shown, an embodiment of the present invention provides a melon seedling grafting device and a grafting method thereof, comprising: a cutting assembly 1, an L-shaped guide rail 2, a stock clamping assembly 3, a scion clamping assembly 4 and a grafting fixing assembly 5; the long side 20 of the L-shaped guide rail 2 is arranged horizontally, and the short side 21 is located at the upper end of the long side 20; the L-shaped guide rail 2 includes a horizontal slider 22 and a vertical slider 23, the horizontal slider 22 is slidably connected to the long side 20, and the vertical slider 23 is slidably connected to the short side 21, and the grafting fixing assembly 5 is fixed at the corner of the L-shaped guide rail 2; multiple stock clamping assemblies 3 are fixed on the horizontal slider 22, multiple scion clamping assemblies 4 are fixed on the vertical slider 23, and the cutting assembly 1 is fixed to the middle section of the long side 20 of the L-shaped guide rail 2; The cutting assembly 1 includes a cutter 10 and a driving element 11, wherein the driving element 11 is connected to the cutter 10, and the cutting edge of the cutter 10 faces the direction of travel of the long side 20 of the L-shaped guide rail 2; The grafting fixing assembly 5 includes a plurality of sleeves 50 and a sleeve fixing frame 51. The sleeve fixing frame 51 is fixed to the long side 20 of the L-shaped guide rail 2. The plurality of sleeves 50 are detachably connected to the upper end of the sleeve fixing frame 51. The stock clamping assembly 3 , the corresponding scion clamping assembly 4 and the sleeve 50 are arranged in a straight line, and the central axes of the three are coplanar.

[0023] Specifically, there are two groups of L-shaped guide rails 2, which are symmetrically arranged, and two linear motors drive the vertical slider 23 and the horizontal slider 22 respectively.

[0024] The horizontal slider 22 assembly moves smoothly along the long side 20 of the L-shaped guide rail 2, driving multiple stock clamping assemblies 3 to move forward synchronously. When the stock reaches the cutting station, the driving element 11 drives the cutter 10 to cut the stock fixed by multiple clamping assemblies at one time. The blade cuts off the growth point and a cotyledon to form a flat grafting slope. The cutter 10 is then reset, and the horizontal slider 22 continues to move to the end of the long side 20. The stock falls accurately into the corresponding positioning sleeve 50 below. At the same time, the vertical slider 23 drives the scion clamping assembly 4 to move vertically downward along the short side 21 of the guide rail, so that the scion insertion sleeve 50 is completely in contact with the grafting surface of the stock. The sleeve 50 firmly fixes the stock and the scion to complete the entire grafting process. The stock clamping assembly 3 and the scion assembly adopt a multi-group parallel design, and with the arranged sleeve 50, multiple stock and scion clamping, cutting and fixing can be completed at one time, which is more efficient than the traditional single-plant grafting. The horizontal and vertical sliders 23 of the L-shaped guide rail 2 are linked to ensure that the incision positions of the stock and scion are automatically aligned, reducing manual adjustment time.

[0025] Optional, reference Figure 1 The driving element 11 includes a linear moving component 111 and a support rod 110. The moving end of the linear moving component 111 is connected to the cutter 10. There is an angle between the linear moving component 111 and the horizontal plane. The support rod 110 supports and fixes the linear moving component 111.

[0026] Specifically, there are two groups of linear guide rails, which are symmetrically arranged on both sides of the L-shaped guide rail.

[0027] The drive element 11 consists of a linear guide and support rods 110. Its adjustable angle ensures that the cutter 10 is always in the optimal cutting position. The tilted layout and support rods 110 form a three-point support system, which not only reduces operating amplitude but also effectively disperses cutting reaction forces, improving equipment stability.

[0028] Optional, reference Figure 1 The support rod 110 is a telescopic rod, and the angle between the cutter 10 and the horizontal plane is 30° to 60°.

[0029] Specifically, the present invention preferably has a cutter 10 angle of 45°.

[0030] The oblique cutting design can better increase the contact area between the rootstock and the scion, ensuring that the cambium is fully aligned. The oblique cutting method effectively reduces the risk of tissue damage. The natural wedge-shaped structure created by the oblique incision not only facilitates precise alignment during grafting, but also forms a stable mechanical fit after joining, effectively preventing slippage. Compared with vertical cutting, 45° oblique cutting can significantly reduce damage to the stem tissue and avoid the common splitting problem. At the same time, the incision surface at this angle forms an ideal fiber arrangement direction, which provides favorable conditions for the rapid growth of callus tissue. This design effectively avoids the problems of stem splitting or medullary cavity cavitation easily caused by traditional vertical cutting. At the same time, the fiber guiding characteristics formed by the oblique incision can also accelerate callus formation. Through a precise mechanical adjustment mechanism, the system can automatically select the optimal cutting angle according to the age of the melon seedling, so that the grafted body heals faster and the survival rate is significantly improved.

[0031] Optional, reference Figure 2 The stock clamping assembly 3 is a first clamping jaw, the scion clamping assembly 4 is a second clamping jaw, the first clamping jaw opening faces the short side 21 of the L-shaped guide rail 2, and the second clamping jaw opening faces the first clamping jaw.

[0032] The symmetrically opposed jaws are arranged to match the motion trajectory of the L-shaped guide rail 2, so that the stock and the scion can be docked accurately.

[0033] Optional, reference Figure 1 , anti-slip rubber pads 6 are fixed on the inner sides of the first clamping jaw and the second clamping jaw.

[0034] The specially designed non-slip rubber sleeve on the inside of the clamping jaws not only ensures sufficient friction when clamping the rootstock, but also effectively buffers the mechanical clamping force to avoid damage to the seedling's epidermal tissue. This non-metallic contact clamping prevents the rootstock from slipping during movement, ensuring zero slip during transportation while reducing the damage rate to the tender stem. The corrugated surface structure of the non-slip rubber sleeve can also adapt to rootstocks of different diameters, significantly improving the equipment's compatibility with different varieties. This design solves the technical pain points of traditional metal clamps that are prone to slipping and damage to seedlings, and is the key foundation for ensuring the precise docking of subsequent grafting surfaces.

[0035] Optional, reference Figure 1 The grafting and fixing component 5 also includes a hot air element 52, which includes multiple air outlet ducts 520 and a main duct 521. The main duct 521 is fixed to the side of the grafting and fixing component 5, and multiple air outlet ducts 520 are fixed to the main duct 521. The air outlet duct 520 corresponds to the sleeve 50.

[0036] The hot air unit contains multiple air outlet ducts 520, and the multiple air outlet ducts 520 are aligned with multiple sleeves 50. After the scion transport unit sends the scion into the sleeve 50, the hot air unit starts and outputs hot air. The hot air is blown out from the multiple air outlet ducts 520, and the sleeve 50 shrinks due to heat, so that the rootstock and the scion are connected and fixed. An array-type hot air outlet layout is adopted, and the air outlet of each air outlet duct 520 is aligned one by one with the sleeve 50, which can realize the simultaneous heat shrinkage and fixation of multiple grafted seedlings, significantly improving the efficiency of batch operations. The hot air effect and the scion transportation are linked in time, and the heat shrinkage is triggered immediately after the scion is inserted into the sleeve 50, avoiding the displacement problem caused by traditional manual fixation. It can not only firmly fix the interface, but also will not compress the vascular bundle, thereby ensuring smooth nutrient transportation and improving the survival rate of the grafted seedlings.

[0037] Optional, reference Figure 4 and Figure 5 The grafting fixing assembly 5 also includes a grafting seat 53, which is fixed on the long side 20 of the L-shaped guide rail 2. A protrusion 510 is fixed at the lower end of the sleeve fixing frame 51. The grafting seat 53 has a groove 530 corresponding to the protrusion 510. The protrusion 510 and the groove 530 are plugged into each other, and the two ends of the grafting seat 53 are rotated to connect the stop block 531.

[0038] The grafting seat 53 is fixedly installed on the long side 20 of the L-shaped guide rail, and a positioning groove 530 is provided on its surface; the lower end of the sleeve fixing frame 51 is processed with a protrusion 510 that matches the groove 530, and the protrusion 510 and the groove 530 are plugged in and matched to achieve rapid positioning and installation. This structure has the following advantages. The protrusion 510-groove 530 matching structure is used to ensure the consistency of the center position of the sleeve 50 after each replacement. The blocks 531 connected by the rotating shaft at both ends of the grafting seat 53 can be rotated and locked to provide additional support during operation. After a single grafting is completed, the sleeve fixing frame 51 can be removed by simply rotating and opening the block 531. The replacement operation can be completed within 15 seconds. This design not only ensures the accurate positioning of the sleeve 50 during the grafting process, but also meets the replacement requirements of the sleeve 50 specifications for different varieties of melon seedlings, significantly improving the applicability and operating efficiency of the equipment.

[0039] Optionally, the sleeve 50 is made of degradable bioplastic.

[0040] While ensuring the fixation of the grafted seedlings, the bioplastic sleeve 50 can naturally degrade into water and carbon dioxide within 3-6 months after transplanting, avoiding the white pollution caused by traditional plastic sleeves 50. There is also no need to manually remove the grafting clamp after the rootstock and scion have grown and fixed, unlike traditional grafting devices, saving manpower and process steps. This material has mechanical strength comparable to polypropylene plastic and can reliably fix the grafting site; its unique microporous structure ensures air permeability while maintaining a suitable humidity environment of 80%-90%, promoting callus formation. In addition, the guide groove design on the inner wall of the sleeve 50 can form a synergistic effect with the anti-slip clamp to ensure that the weight is positioned when it falls. This innovative design not only meets the requirements of sustainable agricultural development, but also improves the survival rate by optimizing the grafting microenvironment.

[0041] Optional, reference Figure 1 , and also includes a collection box 7, which is fixed below the linear moving component 111 and is on the same axis as the cutter 10.

[0042] The collection box 7 can accurately receive the waste of the cut rootstock stems and leaves, keep the work area clean, and prevent the waste from scattering and affecting the subsequent grafting operation; its coaxial design with the cutter 10 ensures that the waste can fall naturally by gravity without the need for an additional power device, which simplifies the structure and improves reliability. The closed collection method effectively prevents plant residues from contaminating the grafting interface and ensures clean contact between the scion and the rootstock. At the same time, this design facilitates the centralized processing of waste tissues, which not only meets agricultural hygiene requirements, but also realizes the unified collection of recyclable resources, significantly improving the continuity and overall efficiency of automated grafting operations.

[0043] like Figures 1 to 5 As shown, the embodiment of the present invention provides a melon seedling grafting device and a grafting method thereof, and the working process is as follows: Step 1: the rootstock clamping component 3 clamps the prepared rootstock seedling, and the scion clamping component 4 clamps the prepared scion seedling; Step 2: When the horizontal slider 22 drives the multiple stock clamping assemblies 3 to the cutting station, the cutting assembly 1 cuts the stock in one go, and the cutter 10 is reset; Step 3: The horizontal slider 22 moves to the end of the long side 20, and the rootstock falls into the corresponding positioning sleeve 50 below. At the same time, the vertical slider 23 drives the scion clamping assembly 4 to move downward, so that the scion insertion sleeve 50 is completely in contact with the grafting surface of the rootstock, and the sleeve 50 fixes the rootstock and the scion.

[0044] The above inventions are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
