Description

Technical Field

[0001] This utility model relates to the field of grafting tools, specifically to a tree bud grafting device. Background Technology

[0002] Grafting is a practical technique created by working people through long-term production practices. Through grafting, the superior characteristics of varieties can be maintained, and fruit trees, vegetables, and other crops can bear fruit and mature earlier.

[0003] Grafting is one of the most widely used asexual reproduction techniques in forestry production. In particular, the application of square budding in pecan grafting has enabled the large-scale and rapid propagation of superior pecan varieties. During summer budding of pecans, bud patches are typically cut using a traditional square budding knife; a patch about 3cm wide with one plump bud is sufficient.

[0004] In traditional budding, the bud falls from the trunk when the bud is cut, and the grower collects it. However, if the trunk is tall, the bud is easily damaged when it falls to the ground. Utility Model Content

[0005] The purpose of this invention is to provide a tree bud grafting device to solve the problem in the prior art where buds fall off the tree trunk when the budding knife is cutting the buds, and if the tree trunk is high, the buds are easily damaged when they fall to the ground.

[0006] To achieve the above objectives, this utility model provides a tree bud grafting device, including...

[0007] Tool holder body;

[0008] A ring-shaped cutting tool is disposed on one side of the tool holder body;

[0009] The pressure-applying part is located on one side of the tool holder body opposite the annular tool;

[0010] The blade holder body has a receiving cavity inside, and the opening of the receiving cavity is connected to the annular opening of the annular blade; pressure is applied to the pressure part so that the annular blade cuts the bud and the bud is received by the receiving cavity.

[0011] Furthermore, the annular cutter includes a sliding portion and a cutting edge portion connected together. The sliding portion is slidably connected to the receiving cavity to adjust the extension length of the cutting edge portion relative to the cutter holder body.

[0012] Furthermore, a limiting device is provided between the sliding part and the tool holder body, and the limiting device fixes the annular tool to the tool holder body.

[0013] Furthermore, the limiting device includes a limiting bolt and a limiting nut. The limiting bolt passes through the tool holder body and the sliding part, and the limiting nut cooperates with the limiting bolt to fix the tool holder body and the sliding part.

[0014] Furthermore, the side wall of the tool holder is provided with a sliding groove, which is arranged along the sliding direction of the sliding part, and the limiting bolt passes through the sliding groove.

[0015] Furthermore, at least two sets of the limiting device and the slide are provided, and they are located on opposite sides of the tool holder body.

[0016] Furthermore, the annular cutter includes a cutting edge portion, which is recessed inward toward the center of the annulus.

[0017] Furthermore, the inward angle of the blade edge is 4° to 6° relative to the vertical direction.

[0018] Furthermore, the pressure-applying part protrudes from the surface of the tool holder body.

[0019] Furthermore, a wound-opening knife is installed on one side of the knife holder body.

[0020] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0021] This utility model discloses a tree bud grafting device. The inside of the blade holder is provided with a receiving cavity. The opening of the receiving cavity is connected to the annular opening of the ring blade to apply pressure to the pressure part. The buds cut by the ring blade fall into the receiving cavity through the annular opening. This allows the ring blade to cut the buds and the receiving cavity to collect the buds, preventing the buds from falling to the ground. On the one hand, this can avoid the buds from falling from the high tree trunk to the ground and being damaged. On the other hand, it facilitates the collection of buds and improves the efficiency of bud collection during grafting.

[0033] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0034] Reference Figures 1-3 This embodiment provides a tree bud grafting device, including a blade holder 100 and a ring-shaped blade 200, the ring-shaped blade 200 being disposed on one side of the blade holder 100. The ring-shaped blade 200 can cut off tree buds in one go, improving slicing efficiency. A pressure applying part 500 is disposed on the blade holder 100 on the side opposite to the ring-shaped blade 200. When cutting buds for grafting, the blade of the ring-shaped blade 200 faces the tree bark, while the pressure applying part 500 faces the worker, facilitating the worker to apply slicing pressure through the pressure applying part 500.

[0035] The blade holder 100 has a receiving cavity 110 inside, and the opening of the receiving cavity 110 is connected to the annular opening of the ring cutter 200. When pressure is applied to the pressure application part 500, the buds cut by the ring cutter 200 fall into the receiving cavity 110 through the annular opening. The receiving cavity 110 catches the buds to prevent them from falling to the ground. This not only avoids damaging the buds when they fall from a high tree trunk, but also facilitates the collection of the buds.

[0036] In actual grafting work, the bark thickness of trees varies, requiring the cutting of bud grafting bark of different thicknesses. In some embodiments, such as Figure 1 and Figure 2As shown, the annular cutter 200 includes a sliding portion 220 and a cutting edge portion 210 connected together. The sliding portion 220 is slidably connected to the receiving cavity 110 to adjust the extension length of the cutting edge portion 210 relative to the cutter holder body 100. When the sliding portion 220 can slide relative to the receiving cavity 110, the overall position of the annular cutter 200 can be adjusted according to the actual situation, so that the cutting edge portion 210 can be lengthened or shortened, thereby cutting grafted buds of different thicknesses.

[0037] Understandably, when the blade 210 extends or retracts to a suitable position, the annular blade 200 needs to be fixed to the blade holder 100 to ensure that the annular blade 200 remains stable when cutting buds. A limiting device 300 is provided between the sliding part 220 and the blade holder 100, and the limiting device 300 fixes the annular blade 200 to the blade holder 100.

[0038] As one embodiment of the limiting device 300, such as Figure 2 As shown, the limiting device 300 includes a limiting bolt and a limiting nut. The limiting bolt passes through the tool holder body 100 and the sliding part 220, and the limiting nut cooperates with the limiting bolt to fix the tool holder body 100 and the sliding part 220. A sliding groove 120 is provided on the side wall of the tool holder body 100, arranged along the sliding direction of the sliding part 220. The limiting bolt passes through the sliding groove 120. When adjusting the position of the ring cutter 200, the limiting nut is loosened, allowing the sliding part 220 to slide against the tool holder body 100. Simultaneously, the limiting bolt moves upward or downward along the sliding groove 120, preventing the limiting bolt from interfering with the position adjustment of the ring cutter 200.

[0039] It should be noted that two sets of limiting devices 300 and sliding grooves 120 are provided, located on opposite sides of the tool holder body 100. The limiting devices 300 located on opposite sides increase the structural strength of the tool holder body 100 and the annular cutter 200 when fixed, facilitating pressure on the tool holder body 100 during bud cutting to ensure the stability of the annular cutter 200. Depending on the actual situation, more than two sets of limiting devices 300 and sliding grooves 120 may also be provided.

[0040] Of course, the limiting device 300 can also be implemented using other mechanical structures. In some other embodiments, a fastening bolt can be threaded onto the tool holder body 100, with the end of the fastening bolt contacting the annular cutter 200, and a tension spring is provided between the annular cutter 200 and the tool holder body 100. Rotating the fastening bolt forward causes the annular cutter 200 to move in the extending direction, while simultaneously stretching the tension spring. Rotating the fastening bolt in the reverse direction causes the fastening bolt to disengage from the annular cutter 200, but under the restoring action of the tension spring, the annular cutter 200 moves towards the fastening bolt, causing the end of the fastening bolt to continue to press against the annular cutter 200. There is a self-locking function between the fastening bolt and the tool holder body 100, thereby keeping the annular cutter 200 fixed.

[0041] When performing budding, it is necessary to cut through the bark (including the epidermis and phloem) while minimizing damage to the internal xylem. In some embodiments, the ring cutter 200 includes a blade portion 210 that is recessed towards the center of the ring, allowing for more stable control of the cutting depth and facilitating the formation of a uniformly deep, completely closed ring-shaped incision. This is crucial for successful grafting, as only with a neat and standardized incision can the cambium layers of the scion and rootstock align and heal effectively.

[0042] Furthermore, this inward-curving blade, when cutting, not only relies on the "cutting" action but also has a certain "compression" effect. For relatively soft bark tissue, this reduces tearing of the underlying fragile cambium cells (responsible for plant thickening and wound healing), thus protecting the plant's natural healing ability. Moreover, the inward curve of the blade (210°) prevents direct contact between the blade and the user when not in use, protecting the user's safety.

[0043] More importantly, the blade 210 is tapered inward, and the area enclosed by the blade of the ring-shaped cutter 200 is smaller than the cross-sectional area of ​​the receiving cavity 110, so that the area of ​​the cut bud is smaller than the cross-sectional area of ​​the receiving cavity 110, making it easier for the bud to be stored in the receiving cavity 110.

[0044] Preferably, the inward angle of the blade portion 210 relative to the vertical direction is 4° to 6°, and can be 4°, 4.2°, 4.5°, 5°, 5.2°, 5.5° and 6°, with 5° being the most preferred.

[0045] In some embodiments, the pressure-applying portion 500 protrudes from the surface of the tool holder body 100. The protruding pressure-applying portion 500 allows for easy application of cutting pressure by striking it with a hammer. Furthermore, the protruding structure resists deformation from impact, improving the structural strength of the tool holder body 100.

[0046] In some embodiments, a sap flow opening knife 400 is installed on one side of the knife holder body 100. The sap flow opening knife 400 can open a sap flow opening near the grafting site after bud grafting to achieve the purpose of drainage and improve the grafting success rate. The knife holder body 100 integrates the functions of cutting buds and opening sap flow openings, which improves the practicality of this device.
