Description

Technical Field

[0001] This utility model relates to the field of camellia seedling grafting equipment, specifically a rootstock cutting device for camellia seedling grafting. Background Technology

[0002] The rootstock cutting device for grafting Camellia oleifera seedlings is a specialized tool used in the grafting process to precisely cut rootstock branches, creating a suitable interface for grafting. It is of great significance for ensuring the survival rate of grafted Camellia oleifera seedlings and cultivating high-quality seedlings. In actual grafting operations, general-purpose devices have prominent problems: insufficient clamping stability of rootstock branches. Due to the differences in thickness and shape of Camellia oleifera rootstock branches, conventional devices are difficult to adapt to branches of different specifications. During cutting, branches are prone to slippage and displacement, resulting in irregular cutting interfaces, affecting the fit between the scion and rootstock, and reducing the grafting survival rate.

[0003] To address the issue of unstable clamping, conventional manufacturers often employ methods such as adding simple spring clips or fixing slots to the cutting blade. These methods utilize the elastic clamping force of the spring clips or the limiting effect of the fixing slots to attempt to fix the rootstock branch in the cutting position. Some devices also optimize the surface roughness of the clamping components to increase friction and prevent branch slippage, thereby improving clamping stability and ensuring the quality of the cutting interface.

[0004] However, conventional techniques have significant drawbacks. On the one hand, the elasticity of simple spring clips is greatly affected by the number of uses and ambient temperature, easily leading to elastic decay and an inability to maintain a stable clamping position. Furthermore, the fixing slots have poor adaptability, only suitable for branches of specific sizes, making them unsuitable for a wide variety of Camellia oleifera rootstock branches. On the other hand, methods to optimize surface roughness have limited effect on increasing friction when the branch surface has sap or moisture, still resulting in slippage. These problems lead to unstable clamping during rootstock cutting, large fluctuations in the quality of the cut interface, and an inability to meet the stringent requirements for precise cutting in Camellia oleifera seedling grafting.

[0005] Therefore, a rootstock cutting device for grafting Camellia oleifera seedlings is proposed to solve the problems mentioned above. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] A rootstock cutting device for grafting Camellia oleifera seedlings includes a blade holder 1. A clamping screw 11 is provided at the upper end of the blade holder 1. A clamping movable bearing 12 is provided on one side of the clamping screw 11. A support arm 10 is provided on both sides of the clamping movable bearing 12. A clamping device 9 is provided at one end of the support arm 10. A rotating shaft 18 is vertically and annularly provided on one side of the front end of the clamping device 9. An anti-detachment plate 17 is provided at the bottom of the rotating shaft 18. A stop plate 16 is provided at the upper end of the front end of the clamping device 9. A limit frame 8 is provided at the upper end of the front end of the clamping device 9. A sliding rod 20 is provided inside the limit frame 8. A slider 19 is slidably provided outside the sliding rod 20. A hinge plate 2 is provided at the top of the slider 19. A spring 21 is provided on one side of the slider 19. A central shaft 6 is vertically provided at the intersection of the clamping device 9 and the front end of the clamping screw 11.

[0028] A cutting screw 15 is provided at the bottom of the tool holder 1. A cutting moving bearing 14 is provided on one side of the cutting screw 15. Cutting arms 3 are provided on both sides of the cutting moving bearing 14. A blade 4 is provided at the front end of the cutting arm 3. A rotating rod 5 is provided on the outside of the blade 4. A wiping plate 7 is provided at the front end of the rotating rod 5. A rotating plate 13 is provided at the end of the cutting screw 15 and the clamping screw 11.

[0029] Example 1: Please refer to Figure 1 - Figure 5 The original abutment 16 was structurally improved by replacing it with an elastically deformable arc-shaped rubber sheet. The original abutment 16 was a rigid structure with limited adaptability to rootstock branches of different diameters and shapes. The elastic arc-shaped rubber sheet has good deformation capability. When the clamping device 9 holds the rootstock branch, the rubber sheet can conform to the surface of the branch, increase the contact area, and improve the clamping friction. When the anti-detachment plate 17 is rotated to adjust the angle of the abutment 16, the rubber sheet can better adapt to the changes in the branch contour, stably hold the branch, and prevent the branch from sliding during the cutting process. At the same time, the elasticity of the rubber sheet can buffer the vibration during cutting, reduce the impact on the clamping structure, and ensure the service life of components such as the clamping device 9 and the clamping arm 10. The performance of the device is optimized from the perspective of clamping adaptability and structural protection.

[0030] The improved clamping plate 16 enhances the adaptability of the clamping device to different rootstock branches, improves clamping stability, reduces the impact of cutting vibration, ensures the durability of the device's structural components, and enables the device to adapt to more diverse camellia rootstock cutting needs.

[0031] Example 2: Please refer to Figure 1 - Figure 5The material of the wiping pad 7 is replaced with a nanofiber cleaning cloth. When the original wiping pad 7 cleans the blade 4, its cleaning effect on fine residual impurities is limited. The nanofiber cleaning cloth has an ultra-high specific surface area and adsorption capacity. When the rotating rod 5 makes the wiping pad 7 fit the blade 4, it can efficiently adsorb wood chips, resin and other residues on the blade. Its soft fiber structure will not damage the blade and is highly durable. It can still maintain good adsorption performance after multiple cleanings. After the blade 4 has finished cutting, cleaning with the nanofiber wiping pad 7 can more thoroughly remove impurities from the blade, ensuring the sharpness and cutting quality of the blade 4 for the next cut, optimizing the blade 4 maintenance process and improving the cutting stability of the device.

[0032] The replacement of the material of the wiping plate 7 improves the cleaning effect of the blade 4, ensures the cutting performance of the blade 4, reduces the problem of reduced cutting quality caused by blade residue, extends the service life of the blade 4, and makes the cutting operation of the device more stable and efficient.

[0033] In use, the user rotates the rotating plate 13 at the end of the clamping screw 11. The rotating plate 13 drives the clamping screw 11 to rotate. The clamping moving bearing 12 moves outside the clamping screw 11. The clamping arms 10 on both sides of the clamping moving bearing 12 start to rotate. The clamping arms 10 drive the clamping device 9 to rotate toward the central shaft 6. The arc-shaped structure at the front end of the clamping device 9 clamps the outside of the grafted branch. At this time, the abutments 16 at the upper and lower ends of the rotating shaft 18 abut against the outside of the branch. The user rotates the anti-detachment plate 17. The anti-detachment plate 17 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the abutment plate 16 to rotate. In this way, the angle of the abutment plate 16 against the outside of the branch can be adjusted. Therefore, the abutment plate 16 can help the clamping device 9 to better clamp the outside of the cut branch.

[0034] Furthermore, when the hinge slice 2 is pressed against the remaining branches extending from the grafted branch, the flat part of the hinge slice 2 is forced to move towards the arc-length structure of the clamp 9. The hinge slice 2 drives the slider 19 to move outside the slide rod 20 inside the limit frame 8, while the spring 21 can reduce the range of movement of the slider 19, so that the excess branches outside the grafted branch are blocked during grafting and cutting and normal use.

[0035] The user rotates the rotating plate 13 at the end of the cutting screw 15 again. The cutting screw 15 rotates, and the cutting movable bearing 14 on the outside of the cutting screw 15 begins to move. The cutting arms 3 on both sides of the cutting movable bearing 14 begin to rotate. The front end of the cutting arm 3 abuts against the blade 4, and the blade 4 begins to rotate. The blade 4 begins to cut the tree branch held inside the clamp 9. After the blade 4 is used up, the user rotates the rotating rod 5, so that the rotating rod 5 drives the wiping plate 7 to rotate onto the blade edge of the blade 4. Then the wiping plate 7 is rotated to clean the blade edge of the blade 4. Because the wiping plate 7 has a trapezoidal structure, the outer edge of the wiping plate 7 will not obstruct the normal use of the blade 4 when the angle is adjusted by rotation.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
