Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of auxiliary grafting devices convenient for forestry use, belong to forestry grafting equipment field. BACKGROUND

[0002] Forestry grafting refers to the branch or bud of one plant is grafted to the stem or root of another plant, so that the two parts grafted together grow into a complete plant, the branch or bud grafted is called scion, and the plant body grafted is called stock. The main principle of successful grafting is the regenerative capacity of plants and the totipotency of cells. There are three common grafting methods: bud grafting, branch grafting, and root grafting. Among them, the branch grafting method uses branches as scions. The branch with several buds is cut into a suitable length of scion, and the lower end is cut into a wedge-shaped or similar shape. The scion is inserted into the cut of the stock, and the cambium of the two is aligned.

[0003] In the prior art, an auxiliary grafting device is needed during branch grafting. The device is in the shape of a blade and cuts the end of the grafted branch. The cutting angle is usually 30°-45°. Since the branch is cut by hand during the cutting process, the bottom end of the branch is not supported, and the blade does not lean against it. This can easily result in an unqualified cutting angle, reducing the survival rate of forestry grafting. At the same time, the phenomenon of wasted branches increases, increasing the consumption of grafted branches.

[0004] Therefore, the utility model provides an auxiliary grafting device convenient for forestry use to solve the above problems. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies of the prior art, the utility model aims to provide an auxiliary grafting device convenient for forestry use to solve the problem of low qualification rate of cutting angle for branch grafting mentioned in the background.

[0006] To achieve the above-mentioned purpose, the utility model is implemented by the following technical solutions: an auxiliary grafting device convenient for forestry use, comprising a sleeve, a first bevel cut is formed at one end of the sleeve, a second bevel cut is formed at the other end of the sleeve, a square groove is formed between the back surface of the sleeve and the back surface of the inner wall, and an adjusting and fixing assembly is embedded in the back surface of the sleeve through the square groove.

[0007] Further, the included angle between the bevel surface of the first bevel cut and the top of the sleeve is °, and the included angle between the bevel surface of the second bevel cut and the top of the sleeve is °.

[0008] Furthermore, the adjusting and fixing assembly includes a mounting base with fastening screws penetrating the top and bottom of the back side of the mounting base. The front side of the mounting base fits against the middle of the back side of the sleeve. The mounting base is fixedly connected to the sleeve by two fastening screws. A threaded rod passes through between the back side and the front side of the mounting base, and a positioning block is installed at one end of the threaded rod inside a square groove.

[0009] Furthermore, a rubber pad is fixedly installed on one side of the positioning block, and one side of the rubber pad is raised with a wavy pattern.

[0010] Furthermore, the threaded rod is threadedly connected to the mounting base, and the end of the threaded rod is rotatably connected to one side of the positioning block via a bearing.

[0011] Furthermore, the positioning block and the square groove are interlocked, and a rotating block is fixedly connected to the other end of the threaded rod.

[0012] Furthermore, threaded holes are provided at the top and bottom of the back of the mounting base to engage with the fastening screws, and the ends of the threaded holes extend to the back of the sleeve.

[0013] The beneficial effects of this utility model are:

[0014] By sequentially threading the end of the branch to be grafted through the first and second oblique cuts on the sleeve, the angle between the oblique surface of the first oblique cut and the top of the sleeve is 45°, and the angle between the oblique surface of the second oblique cut and the top of the sleeve is 30°. The first and second oblique cuts can limit the oblique cutting angle of the end of the grafted branch, ensuring that the oblique cutting angle of the branch end is qualified, avoiding the phenomenon that the oblique cutting angle of the branch end is too small to complete the grafting operation, thereby effectively improving the survival rate of forestry grafting and reducing the consumption of grafted branches.

[0015] By rotating the rotating block inside the fixing component, the threaded rod can be moved while rotating, thereby adjusting the distance between the positioning block and the inner wall of the sleeve. This allows for clamping and fixing of branches that penetrate the sleeve, and can be effectively adjusted according to the thickness of the branches, thus improving the adaptability of the auxiliary grafting device.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-4 This utility model provides a technical solution: an auxiliary grafting device convenient for forestry use, including a sleeve 1. One end of the sleeve 1 has a first oblique cut 2, and the other end of the sleeve 1 has a second oblique cut 3. A square groove 5 is formed between the back of the sleeve 1 and the back of the inner wall. An adjustment and fixing component 4 is embedded in the back of the sleeve 1 through the square groove 5. The angle between the oblique surface of the first oblique cut 2 and the top of the sleeve 1 is 45°, and the angle between the oblique surface of the second oblique cut 3 and the top of the sleeve 1 is 30°. In the T-budding process of bud grafting, the lower end of the bud patch on the scion branch is generally cut at a 30°-45° angle. The angled cut of the bud at approximately 45° allows for a larger contact area between the bud and the rootstock, facilitating the insertion of the bud into the incision in the rootstock. This promotes alignment and healing of the cambium layers. In inlay budding, the bud is typically cut at a 45° angle, and a similar angle is made on the rootstock before embedding the bud. This angle ensures a tight fit between the bud and rootstock, increasing the contact area and improving the survival rate. In side grafting, the scion's angled cut is typically between 45° and 60°. A larger angled cut allows for a larger contact area between the scion and rootstock, enabling better nutrient absorption and increasing the grafting success rate. The first angled cut (2) limits the angled cut at the end of the grafted branch, ensuring a 45° angle. The second angled cut (3) limits the angled cut at the end of the grafted branch, ensuring a 30° angle, preventing grafting from being impossible due to an insufficient angle.

[0024] Please see Figures 2-4The adjusting and fixing component 4 includes a mounting base 41. Fastening screws 42 pass through the top and bottom of the back of the mounting base 41. The front of the mounting base 41 fits against the middle of the back of the sleeve 1. The mounting base 41 is fixedly connected to the sleeve 1 by two fastening screws 42. A threaded rod 43 passes through the back and front of the mounting base 41. A positioning block 45 is installed at one end of the threaded rod 43 and inside the square groove 5. When the threaded rod 43 rotates, it can push the positioning block 45 to move inside the square groove 5 toward the inside of the sleeve 1. The positioning block 45 is in the shape of a round flat block. The gap between the positioning block 45 and one side of the inner wall of the sleeve 1 is reduced, so that the branch placed inside the sleeve 1 can be clamped and fixed.

[0025] Please see Figures 2-4 A rubber pad 46 is fixedly installed on one side of the positioning block 45. One side of the rubber pad 46 is wavy and raised, which can increase the friction between the rubber pad 46 and the branch surface. The rubber pad 46 is soft and elastic. The rubber pad 46 can protect the bark of the branch from being scratched during the clamping process of the positioning block 45. At the same time, the rebound force of the rubber pad 46 can apply a reverse thrust to the positioning block 45, which can make the threaded connection between the threaded rod 43 and the internal threaded groove of the mounting base 41 tighter. The threaded rod 43 is threadedly connected to the mounting base 41. The end of the threaded rod 43 is rotatably connected to one side of the positioning block 45 through a bearing. The positioning block 45 and the square groove 5 are interlocked. The other end of the threaded rod 43 is fixedly connected to a rotating block 44. The top and bottom of the back of the mounting base 41 are provided with threaded holes for threaded connection with fastening screws 42, and the ends of the threaded holes extend to the back of the sleeve 1.

[0026] Specific implementation method: The end of the branch to be grafted is sequentially passed through the first oblique cut 2 and the second oblique cut 3 on the sleeve 1. The angle between the oblique cut surface of the first oblique cut 2 and the top of the sleeve 1 is 45°, and the angle between the oblique cut surface of the second oblique cut 3 and the top of the sleeve 1 is 30°. In the T-budding process of bud grafting, the lower end of the bud on the scion is generally cut at an oblique angle of 30°-45°. This angle allows for a larger contact area between the bud and the rootstock, and facilitates the insertion of the bud into the cut of the rootstock, which is beneficial for the alignment and healing of the cambium layers. In inlay budding, the bud is usually cut at an oblique angle of about 45°, and a similar angle is cut on the rootstock. The bud is then inserted. This angle allows the bud and the rootstock to be tightly embedded, increasing the contact area and improving the survival rate. In side grafting, the oblique cut angle of the scion is usually between 45° and 60°. A larger oblique cut angle allows for a closer fit between the scion and the rootstock. The larger contact area allows for better nutrient absorption from the rootstock, increasing the grafting success rate. The first oblique cut 2 limits the oblique cutting angle at the end of the grafted branch, ensuring a 45° angle. The second oblique cut 3 limits the oblique cutting angle at the end of the grafted branch, ensuring a 30° angle. This prevents grafting from being impossible due to an excessively small oblique cutting angle, thus effectively improving the survival rate of forestry grafting and reducing the consumption of grafted branches.

[0027] After the branch is placed inside the sleeve 1, the rotating block 44 inside the adjusting fixing component 4 is rotated clockwise, which drives the threaded rod 43 to rotate clockwise. As the threaded rod 43 rotates, it moves on the mounting base 41 and pushes the positioning block 45 inside the square groove 5 towards the inside of the sleeve 1. The distance between the positioning block 45 and one side of the inner wall of the sleeve 1 decreases, thus clamping and fixing the branch placed inside the sleeve 1. One side of the rubber pad 46 has a wavy, raised pattern, which increases the friction between the rubber pad 46 and the surface of the branch. The rubber pad 46 is relatively soft and elastic, and can protect the bark of the branch from scratches during the clamping process of the positioning block 45. At the same time, the rebound force of the rubber pad 46 can apply a reverse thrust to the positioning block 45, so that the threaded connection between the threaded rod 43 and the internal thread groove of the mounting base 41 can be tighter. When the rotating block 44 rotates counterclockwise, it drives the threaded rod 43 to rotate counterclockwise, which can drive the positioning block 45 to move in the opposite direction, thereby expanding the clamping distance inside the sleeve 1. This allows for effective adjustment according to the thickness of the branch, effectively improving the adaptability of the auxiliary grafting device.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
