Description

Technical Field

[0001] This utility model relates to the field of fruit tree planting tools, specifically to a fruit tree bud-cutting knife. Background Technology

[0002] In the process of fruit tree planting and management, bud notching is an important operation. Its purpose is to regulate the distribution of nutrients in the fruit tree by making incisions in the bark above or below the bud, thereby promoting bud germination, branching, or the formation of flower buds, and thus achieving the effects of shaping and pruning the fruit tree and improving the fruiting rate. Currently, fruit growers mostly use ordinary knives, scissors, or specialized bud-notching tools when performing bud-notching operations. However, these existing tools have many shortcomings. Ordinary knives and scissors are not specifically designed for bud-notching on fruit trees, making it difficult to accurately control the depth and width of the notch. This can easily lead to problems such as notching too deeply, damaging branches and causing disease infection, or not notching too shallowly, failing to achieve the desired bud-notching effect. On the other hand, ordinary tools are usually only suitable for notching branches of a specific thickness, lacking versatility and failing to meet the fruit growers' needs for efficient and convenient bud-notching.

[0014] Using the aforementioned fruit tree bud-notching knife, specifically in the application of bud notching on fruit trees, the blade mounting box is assembled at the top of the knife handle, and the bud-notching blade assembly with bud-notching depth adjustment function is assembled inside the blade mounting box. This allows for convenient bud notching of branches by having the blade engage with the notch and press down to allow the arc-shaped groove of the blade body to penetrate the branch, thus meeting the needs of fruit farmers for efficient and convenient bud notching. Furthermore, the depth of the arc-shaped groove penetrating the branch is limited by the branch contacting the bottom of the blade's engagement notch. Simultaneously, the guide stud slides vertically along the adjustment groove, and the locking mechanism is tightened. The nut mechanism allows for height adjustment of the blade body, and consequently, adjustment of the length of the arc-shaped groove extending beyond the bottom of the blade's mating notch. This allows for adaptive adjustment of the notch depth through the arc-shaped groove adjustment. The notch depth adjustment method is simple and easy to operate, facilitating adjustment according to actual usage needs to achieve the desired notch effect. Furthermore, because anti-loosening screws are inserted into the top of both sides of the blade mounting box, these anti-loosening studs prevent the blade body from accidentally detaching from the top of the blade mounting box. Additionally, the adjustment... The top of the groove is open. After removing the anti-loosening screw and loosening the locking nut, the guide stud can slide vertically upwards along the adjustment groove, allowing it to sequentially slide out of the adjustment groove and the top of the blade mounting box. This allows the blade body and the blade mounting box to be separated, facilitating subsequent maintenance and replacement of the blade body. Furthermore, due to the vertical sliding engagement between the blade holder body and the fixing sleeve of the disassembly assembly, and the longitudinal sliding engagement between the limiting rod and the limiting hole, the blade mounting box and the engraving blade assembly can be detachably assembled together on the top of the blade holder body. The assembly of the blade assembly together on the top of the blade holder body is simple and easy to implement, thus facilitating the use of the blade mounting box and the bud-marking blade assembly together on the top of the blade holder body for bud-marking operations on fruit trees. Simultaneously, simply pulling the limiting rod out of the limiting hole allows the blade mounting box to move upwards and separate from the blade holder body, enabling the blade mounting box and the bud-marking blade assembly to be detached from the top of the blade holder body. The method of separating the blade mounting box and the bud-marking blade assembly from the top of the blade holder body is simple and easy to implement, facilitating subsequent inspection and maintenance after detachment.

[0015] The beneficial effects are as follows: 1. The present invention has a blade mounting box assembled on the top of the blade holder body, and a bud-cutting blade assembly with bud-cutting depth adjustment function is assembled in the blade mounting box. By using the blade to engage with the notch to hold the branch and press down to press the arc-shaped groove of the blade body into the branch, the bud-cutting operation of the branch can be conveniently performed, which meets the needs of fruit farmers for efficient and convenient bud-cutting. 2. Because the depth of the arc-shaped notch pressed into the branch can be limited by the contact between the branch and the blade with the bottom of the notch, and the blade body can be raised and lowered by the guide stud sliding vertically along the adjustment groove and tightening the locking nut, the length of the arc-shaped notch extending out of the blade and into the bottom of the notch can be adjusted. Thus, the depth of the notch can be adaptively adjusted by adjusting the arc-shaped notch. The method of limiting and adjusting the notch depth is simple and easy to operate, and it is convenient to adjust the notch depth according to the actual use needs to achieve the desired notch effect. 3. Anti-loosening screws are inserted into the top of both sides of the blade mounting box. These anti-loosening screws prevent the blade body from accidentally coming out of the top of the blade mounting box. Since the top of the adjustment groove is open, after removing the anti-loosening screws and loosening the lock nut, the guide stud can slide vertically upward along the adjustment groove to disengage from the adjustment groove and the top of the blade mounting box. This allows the blade body to be separated from the blade mounting box for easy maintenance and replacement of the blade body. 4. By vertically sliding the blade holder body and the fixed sleeve of the assembly and disassembly assembly together, and by longitudinally sliding the limiting rod and the limiting hole together, the blade mounting box and the bud-marking blade assembly can be detachably assembled together on the top of the blade holder body. The assembly method of the blade mounting box and the bud-marking blade assembly together on the top of the blade holder body is simple and easy to achieve, which makes it convenient to use the blade mounting box and the bud-marking blade assembly together on the top of the blade holder body for fruit tree bud-marking operations. 5. Simply pull the limiting rod out of the limiting hole to move the blade mounting box upward and separate it from the tool holder body. This allows the blade mounting box and the engraving blade assembly to be removed from the top of the tool holder body together.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] See Figures 1-8 As shown, this utility model provides a fruit tree bud-notching knife, including a knife handle body 2. A blade mounting box 1 is assembled on the top of the knife handle body 2. The blade mounting box 1 is a hollow box with an open top, and a bud-notching blade assembly 3 with adjustable bud-notching depth is assembled inside the blade mounting box 1. Specifically, the bud-notching blade assembly 3 includes a blade body 302 and a blade mating notch 301. The blade body 302 is inserted into the blade mounting box 1 in a vertical sliding fit. The top edge of the blade body 302 is a cutting notch. The blade body 302 has a recessed arc-shaped groove 306 at the center of its top edge. The blade mounting box 1 has vertically extending blade mating notches 301 on its front, rear, and top sides, all of which are through grooves in the longitudinal direction. The blade mating notches 301 and the arc-shaped groove 306 are aligned front to back. An adjustment groove 303 is vertically extending along the lower front part of the blade mounting box 1, and this groove is also a through groove in the longitudinal direction. A guide stud 30 is fixed longitudinally along the lower front part of the blade body 302. 7. The guide stud 307 slides through the adjustment groove 303 and can slide vertically up and down along the adjustment groove 303. The part of the guide stud 307 extending out of the front end of the adjustment groove 303 is coaxially engaged with a locking nut. The purpose of this setting is to firstly, by using the blade engagement notch 301 to hold the branch and press down to press the arc-shaped cutting groove 306 of the blade body 302 into the branch, a convenient bud notching operation can be achieved. At the same time, the depth of the arc-shaped cutting groove 306 pressed into the branch can be limited by the branch contacting the bottom end of the blade engagement notch 301. Furthermore, by the guide stud 307 sliding vertically along the adjustment groove 303 and tightening the locking nut, the blade body 302 can be raised and lowered. Subsequently, the length of the arc-shaped cutting groove 306 extending out of the bottom end of the blade engagement notch 301 can be adjusted. Thus, the bud notching depth can be adaptively adjusted by adjusting the arc-shaped cutting groove 306. The method of limiting and adjusting the bud notching depth is simple and easy to operate.

[0021] See Figures 1-7As shown, a disassembly and assembly assembly 4 is provided between the tool holder body 2 and the blade mounting box 1. The blade mounting box 1 is detachably fixed to the top of the tool holder body 2 via the disassembly and assembly assembly 4. Specifically, the disassembly and assembly assembly 4 includes a limiting hole 404 and a fixing sleeve 403. The limiting hole 404 is longitudinally formed on the top front of the tool holder body 2 and is a through hole. The fixing sleeve 403 is vertically fixed on the bottom surface of the blade mounting box 1, and the tool holder body 2 is inserted into the fixing sleeve 403 in a vertical sliding fit. The fixing sleeve 405 is longitudinally formed on the front of the fixing sleeve 403 and passes through the rear end face of the fixing sleeve 403. A limiting rod 406 is slidably inserted into the mounting hole 405 in a longitudinal fit, and the rear end of the limiting rod 406 passes through the rear end of the limiting hole 404 and the mounting hole 405 in sequence. A hand is coaxially fixed to the front end of the limiting rod 406 extending out of the mounting hole 405. The handle 401 and the limiting rod 406 are located in front of the fixed sleeve 403 and between the handle 401 and the fixed sleeve 403, respectively. A spring 402 is coaxially fitted between them, and both ends of the spring 402 are fixedly connected to the handle 401 and the front of the fixed sleeve 403. The purpose of this arrangement is that, through the vertical sliding engagement between the tool holder body 2 and the fixed sleeve 403 of the disassembly and assembly assembly 4, and the longitudinal sliding engagement between the limiting rod 406 and the limiting hole 404, the blade mounting box 1 and the engraving blade assembly 3 can be detachably assembled together on the top of the tool holder body 2. At the same time, by simply pulling the limiting rod 406 out of the limiting hole 404, the blade mounting box 1 can be moved upward and separated from the tool holder body 2. In this way, the blade mounting box 1 and the engraving blade assembly 3 can be detached together from the top of the tool holder body 2. The assembly and disassembly of the blade mounting box 1 and the engraving blade assembly 3 together on the top of the tool holder body 2 is simple and easy to implement.

[0022] See Figures 1-8As shown, the following optimizations have been made to this application. Specifically, the upper part of the blade mating notch 301 is a rectangular straight groove, and the lower part of the blade mating notch 301 is an arc-shaped groove that runs in the same direction as the arc-shaped groove 306. When the bottom end of the blade body 302 contacts the inner bottom surface of the blade mounting box 1, the arc-shaped groove 306 is flush with the lower part of the blade mating notch 301, so that the blade body 302 can descend until the arc-shaped groove 306 is covered and hidden by the bottom end of the blade mating notch 301. This allows the blade body 302 to be hidden and stored when not in use, achieving a safe storage effect when not in use. Optionally, the adjustment groove 303 is a vertically arranged waist-shaped elongated groove, with the top of the adjustment groove 303 open and connected to the bottom of the blade mating notch 301. When the bottom end of the blade body 302 contacts the bottom surface of the blade mounting box 1, the outer bottom of the guide stud 307 is in contact with the bottom of the adjustment groove 303. This arrangement facilitates the guide stud 307 to slide upwards and disengage from the top of the adjustment groove 303, and also allows the adjustment groove 303 to have a wider vertical adjustment range. Furthermore, it provides a clear indication when the blade body 302 is adjusted to its lowest position by the outer bottom of the guide stud 307 contacting the bottom of the adjustment groove 303.

[0023] See Figures 1-8 As shown, the locking nut is a hand-tightened knurled nut, and an anti-detachment end 305 is coaxially fixed to the outer end of the guide stud 307. This design allows the locking nut to be tightened and loosened directly by hand, and also prevents the locking nut from accidentally detaching from the outer end of the guide stud 307 using the anti-detachment end 305. Optionally, anti-detachment screws 101 are inserted into the top of both sides of the blade mounting box 1, and these screws are inserted into the interior of the blade mounting box 1. This design prevents the blade body 302 from accidentally detaching from the top of the blade mounting box 1. Alternatively, the lower part of the front end face of the blade handle body 2 is covered with a handle pad 201 to facilitate the fruit farmer's grip during bud-marking operations. Furthermore, both the tool holder body 2 and the fixing sleeve 403 have rectangular horizontal cross-sectional shapes, and the top of the tool holder body 2 is in close contact with the inner top of the fixing sleeve 403. This design facilitates good positioning and guidance when the tool holder body 2 and the fixing sleeve 403 are vertically aligned. At the same time, as the limiting hole 404 slides vertically with the tool holder body 2, when the limiting hole 404 moves to be coaxial with the limiting rod 406, the contact between the top of the tool holder body 2 and the inner top of the fixing sleeve 403 provides a clear indication.

[0024] Using the above structure, specifically for fruit tree bud notching, a blade mounting box 1 is assembled at the top of the blade body 2, and a bud notching blade assembly 3 with bud notching depth adjustment function is assembled inside the blade mounting box 1. This allows for convenient bud notching of branches by using the blade to engage with the notch 301 to hold the branch and pressing down to allow the arc-shaped cutting groove 306 of the blade body 302 to be pressed into the branch, meeting the needs of fruit farmers for efficient and convenient bud notching. Furthermore, the depth of the arc-shaped cutting groove 306 pressed into the branch is limited by the branch contacting the bottom of the blade engagement notch 301. Simultaneously, the guide stud 307 slides vertically along the adjustment groove 303 and is locked by tightening. The nut mechanism allows for height adjustment of the blade body 302, which in turn allows for extension and retraction adjustment of the length of the arc-shaped groove 306 extending from the bottom of the blade-fitting notch 301. This extension and retraction of the arc-shaped groove 306 enables adaptive adjustment of the notch depth. The method for limiting and adjusting the notch depth is simple and easy to operate, facilitating adjustment according to actual usage needs to achieve the desired notch effect. Furthermore, because anti-loosening screws 101 are inserted into the top of both sides of the blade mounting box 1, these anti-loosening studs prevent the blade body 302 from accidentally detaching from the top of the blade mounting box 1. Because the top of the adjusting groove 303 is open, after removing the anti-loosening screw 101 and loosening the locking nut, the guide stud 307 can slide vertically upward along the adjusting groove 303, allowing it to slide out of the adjusting groove 303 and the top of the blade mounting box 1. This allows the blade body 302 to be separated from the blade mounting box 1, facilitating subsequent maintenance and replacement of the blade body 302. Furthermore, due to the vertical sliding engagement between the tool holder body 2 and the fixing sleeve 403 of the disassembly and assembly assembly 4, and the longitudinal sliding engagement between the limiting rod 406 and the limiting hole 404, the blade mounting box 1 and the engraving blade assembly 3 can be detachably assembled together on the top of the tool holder body 2. The assembly of the mounting box 1 and the bud-marking blade assembly 3 together on the top of the blade holder body 2 is simple and easy to implement, which facilitates the use of the mounting box 1 and the bud-marking blade assembly 3 together on the top of the blade holder body 2 for bud-marking operations on fruit trees. At the same time, by simply pulling the limiting rod 406 out of the limiting hole 404, the mounting box 1 can be moved upward and separated from the blade holder body 2. This allows the mounting box 1 and the bud-marking blade assembly 3 to be removed from the top of the blade holder body 2. The method of separating the mounting box 1 and the bud-marking blade assembly 3 together on the top of the blade holder body 2 is simple and easy to implement, which facilitates subsequent inspection and maintenance after the mounting box 1 and the bud-marking blade assembly 3 are removed from the top of the blade holder body 2.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
