Description

Technical Field

[0001] This utility model belongs to the field of grafting knife technology, specifically relating to a grafting knife device for grafting magnolia. Background Technology

[0002] Magnolia is a common ornamental tree species with significant horticultural and ecological value. Since superior varieties are typically propagated through grafting, the grafting survival rate is a crucial indicator for seedling production. However, during magnolia grafting, the cut surfaces of the scion and rootstock are prone to oxidative browning, primarily due to the rapid oxidation of phenolic substances at the cut in the air. This phenomenon severely affects tissue healing quality and reduces the grafting success rate.

[0003] Existing methods for preventing browning typically rely on manually spraying antioxidant and anti-browning protective liquids, such as PVP (polyvinylpyrrolidone iodine) aqueous solutions, after grafting. However, this method of cutting first and then spraying the liquid is cumbersome, inefficient, and results in delayed reactions. Therefore, there is an urgent need for a grafting knife device specifically designed for magnolia grafting that integrates spraying and cutting functions to achieve simultaneous cutting and protection, thereby improving grafting efficiency and quality. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a grafting knife device for magnolia grafting, which allows the operator to spray protective liquid immediately after the cutting action, thereby improving the grafting survival rate.

[0005] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A grafting knife device for magnolia grafting includes a handle and a blade connected to the handle. The handle is provided with a medicine storage tank, a spray pump connected to the medicine storage tank, and a battery and a button electrically connected to the spray pump. The spray pump is connected to a nozzle through a spray pipe. A limit block is connected to the blade, and the nozzle is connected to the limit block.

[0007] Furthermore, the blade is provided with a first through hole, and the limiting block corresponds to the position of the first through hole. The limiting block includes a ring block connected to the blade and a slide block connected to the ring block. The slide block is located in the first through hole and has a slide. The nozzle is provided with a slider corresponding to the slide. The slider slides on the slide to switch the nozzle between a first position and a second position. In the first position, the nozzle is located on one side of the blade, and in the second position, the nozzle is located on the other side of the blade.

[0008] Furthermore, the nozzle is oriented towards the cutting edge of the blade.

[0009] Furthermore, one end of the slide block is located on one side of the blade, and the other end of the slide block is located on the other side of the blade.

[0010] Furthermore, the first through hole is a circular hole.

[0011] Furthermore, the medicine storage tank is equipped with a dosing pipe, and a plug is detachably connected to the dosing pipe.

[0012] Furthermore, the spray tube is a flexible hose.

[0013] Furthermore, the knife handle is provided with a perforated hole corresponding to the medicine storage container.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0015] 1. By setting up a handle, blade, storage tank, spray pump and nozzle, the cutting function of the knife and the protective liquid spraying function are integrated into one. The operator can spray an antioxidant and anti-browning protective liquid (such as PVP aqueous solution) immediately after completing the cutting action to form a protective layer on the cut surface, thereby effectively slowing down the oxidation process, solving the problem of browning that easily occurs after the cut surface is exposed in the traditional grafting process, improving the tissue healing rate between the scion and the rootstock, and significantly improving the grafting survival rate.

[0016] 2. The medicine storage tank is built into the middle of the knife handle, which facilitates the movement and use of the knife in complex environments. The medicine storage tank is made of transparent material and the knife handle is equipped with corresponding perforated holes, which makes it easy for personnel to observe the remaining amount of protective liquid.

[0017] 3. It has a compact structure and is easy to operate, making it suitable for field operations or nursery use. Compared with traditional spray treatment methods, it sprays more promptly and can complete the spraying within 0.5 seconds, significantly reducing the oxidation reaction start-up time.

[0018] 4. A first through hole is provided on the blade, and a limiting block is connected to the first through hole. The nozzle is slidably connected to the limiting block, and the nozzle can switch between working on both sides of the blade. Switching between the two sides not only adapts to the spraying needs of the inner and outer sides of the grafting blade, but also adapts to both left and right hands when holding the grafting blade, which greatly facilitates the operator's use.

It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] like Figure 1 and Figure 2 As shown, a grafting knife device for magnolia grafting includes a handle 1 and a blade 2. Both the handle 1 and the blade 2 are strip-shaped. One end of the handle 1 is connected to the rear end of the blade 2. The blade 2 is made of metal, with a pointed tip and a sharpened lower edge. The handle 1 is a flattened cylinder. A storage tank 3 is installed inside the handle 1. The storage tank 3 is a horizontally arranged cylindrical tank used to store an antioxidant and anti-browning protective liquid, such as a PVP (polyvinylpyrrolidone iodine) aqueous solution. The storage tank 3 is made of transparent material. Hollow holes corresponding to the storage tank 3 are provided on both sides of the handle 1, allowing observation of the liquid level inside the storage tank 3. A dosing tube 31 is provided at the upper rear end of the storage tank 3. A stopper 32 is detachably connected to the dosing tube 31. Opening the stopper 32 allows the protective liquid to be added to the storage tank 3.

[0026] like Figure 1 and Figure 2 As shown, a spray pump 4 is installed inside the handle 1. The spray pump 4 is an existing electric micro spray pump. The inlet pipe of the spray pump 4 is connected to the medicine tank 3, so that protective liquid can be drawn from the medicine tank 3. The handle 1 is also equipped with a battery 51 and a button 52. The battery 51 is located in the upper area of ​​the medicine tank 3 and is electrically connected to the spray pump 4 to provide working power. The handle 1 is equipped with an existing battery charging port that is electrically connected to the battery 51 for connecting to an external power source for charging. The button 52 is electrically connected to the battery 51 and the spray pump 4 to control the power supply. The button 52 is circular and protrudes from one side of the handle 1, making it convenient for personnel to press directly with their fingers. After pressing the button 52, the spray pump 4 is powered on and works.

[0027] like Figure 1 and Figure 2As shown, the spray pump 4 is connected to the nozzle 42 via the spray pipe 41. The outlet pipe of the spray pump 4 is connected to the spray pipe 41. The spray pipe 41 is an existing transparent plastic hose. The spray pipe 41 is located outside the handle 1. One end of the spray pipe 41 is connected to the spray pump 4, and the other end is connected to the nozzle 42. When the spray pump 4 is working, it draws the antioxidant liquid from the storage tank 3 and sprays it out of the nozzle 42. The nozzle 42 is facing the blade 2. When grafting magnolia, the operator can press the button 52 immediately after completing the cutting action. The spray pump 4 will work, and the nozzle 42 will spray the protective liquid towards the cut surface, forming a protective layer on the cut surface, thereby effectively slowing down the oxidation process, improving the tissue healing rate between the scion and the rootstock, and significantly improving the grafting survival rate.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a first through hole 201 is provided in the front part of the upper middle section of the blade 2. The first through hole 201 is near the back of the blade and is a circular hole. A limiting block 6 is connected to the blade 2. The position of the limiting block 6 corresponds to the position of the first through hole 201. The limiting block 6 includes a ring block 61 and a slide block 62. The ring block 61 passes through the first through hole 201 and is connected to the blade 2 above the first through hole 201 (the ring block 61 can be integrally and tightly connected to the blade 2 by injection molding). The slide block 62 is connected to the lower end of the ring block 61 and passes through the first through hole 201. One end of the slide block 62 is located on one side of the blade 2, and the other end is located on the other side of the blade 2. A slide 621 is provided on the lower end surface of the slide block 62. The slide 621 is a T-shaped slide. The nozzle 42 is provided with a slider 421 corresponding to the slide 621. The slider 421 is a T-shaped block. 1. The nozzle 42 can slide within the slide rail 621, thereby connecting the nozzle 42 to the limiting block 6 via the slider 421. The slider 421 slides on the slide rail 621 to switch the nozzle 42 between the first position and the second position (the spray pipe 41 is a flexible hose with a certain length of redundancy, which will not affect the short-distance movement of the nozzle 42). In the first position, the nozzle 42 is located on one side of the blade 2, and in the second position, the nozzle 42 is located on the other side of the blade 2. For example, when the cut surface of the scion and the rootstock is located on the inside of the blade 2, the nozzle 42 is slid to the inside of the blade 2 in advance. When the cut surface of the scion and the rootstock is located on the outside of the blade 2, the nozzle 42 is slid to the outside of the blade 2 in advance. The nozzle 42 can switch between the two sides of the blade 2, which not only meets the spraying needs of the inner and outer sides of the grafting knife, but also allows for use by both left and right hands when holding the grafting knife, greatly facilitating the operator.

[0029] Actual experiments show that within 14 days after grafting, magnolia scions treated with this device exhibit significant callus formation, an average reduction in browning degree of approximately 40%, and an increase in graft survival rate of 15%–25%. This device is not only suitable for magnolias but can also be extended to the grafting treatment of other browning-sensitive plants, such as purple magnolias. It has good practical value and promising prospects for widespread application.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
