Description

Technical Field

[0001] This invention relates to the field of grafting tools, and in particular to a portable mulberry grafting device. Background Technology

[0002] Mulberry branch grafting is one of the most widely used grafting methods for mulberry trees in the field. This method uses branches (scions) of one mulberry variety to graft onto another mulberry rootstock. This method has a high survival rate, produces vigorous seedlings, and can flower and bear fruit earlier. It can cultivate seedlings with good tree shape in a short period of time, restore the original tree yield, and create ideal economic benefits. It is mainly used for the rejuvenation and renewal of old mulberry trees in mulberry orchards, the replacement of old trees with improved varieties, and the cultivation of improved varieties.

[0003] Traditional hand-grafting of mulberry trees is a complex process requiring the guidance of professional technicians. The main steps include using pruning shears and a grafting knife to cut the scion and tearing open the bark of the rootstock to form the grafting bag. During traditional hand-grafting, tools need to be frequently switched, and the sharp blade can easily cause injury to the grafting personnel. Furthermore, the width and length of the bag opening must correspond to the cut surface of the scion and must not contain any woody parts or wrinkled bark. Overall, traditional hand-grafting of mulberry trees is time-consuming, labor-intensive, prone to injury, and has low grafting efficiency.

[0004] On the other hand, current mechanized grafting devices are mainly suitable for indoor grafting, are relatively large and cannot meet the needs of field operations, and are primarily used for hardwood grafting, which is not suitable for mulberry bark grafting. Therefore, this application proposes a portable mulberry grafting device, providing a new technical solution to address the aforementioned technical problems. Summary of the Invention

[0005] Therefore, it is necessary to provide a portable mulberry grafting device to address the aforementioned technical problems. Through the coordinated design of multiple structures, the device can perform three functions: cutting scions, slicing scions, and peeling bark.

It effectively improves grafting efficiency, reduces the complexity of the process, and has a compact overall structure that is easy to carry.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0041] Example 1:

[0042] Please refer to Figure 1 - Figure 7 A portable mulberry grafting device, comprising:

[0043] The device housing 1 has an insertion channel 2 at one end, a scion discharge window 3 at the lower end, and a debris discharge window at the upper end. The lower end of the scion discharge window 3 is detachably connected to a storage box for holding scions and for gripping, thus improving the ease of use of the device.

[0044] The device housing 1 is equipped with a first guide mechanism 5, a second guide mechanism 6, a third guide mechanism 7, a cutting mechanism 8, a first shaving mechanism 9, and a second shaving mechanism 10. The first guide mechanism 5 is located near the insertion channel 2, and the cutting mechanism 8 is located at the end of the first guide mechanism 5 away from the insertion channel 2.

[0045] Inside the device housing 1, at the location of the scion discharge window 3, a scion discharge frame 41 is fixedly connected. Inside the device housing 1, between the cutting mechanism 8 and the scion discharge frame 41, a branch guide frame 40 is fixedly connected. The end of the branch guide frame 40 near the scion discharge frame 41 is inclined. The second guide mechanism 6 and the third guide mechanism 7 are both located above the branch guide frame 40. The second guide mechanism 6 is located at the end of the branch guide frame 40 near the cutting mechanism 8, and the third guide mechanism 7 is located at the end of the branch guide frame 40 near the scion discharge frame 41.

[0046] The first cutting mechanism 9 is located on the upper part of the inner side of the device housing 1 and close to the third guide mechanism 7. The second cutting mechanism 10 is located above the branch guide frame 40 and at the bending position of the branch guide frame 40.

[0047] Among them, the cutting mechanism 8 is used to cut the branches into small sections;

[0048] The second cutting mechanism 10 is used to cut a small section on one side of a small branch; in order to facilitate the discharge of debris cut by the second cutting mechanism 10, a debris discharge through hole 24 is provided on the branch guide frame 40, and the debris discharge through hole 24 corresponds to the position of the second cutting mechanism 10.

[0049] Among them, the first cutting mechanism 9 is used to cut a large arc-shaped bevel on the other side of a small branch;

[0050] Among them, the first guiding mechanism 5, the second guiding mechanism 6, and the third guiding mechanism 7 are used for guiding and transporting branches and small branches, respectively;

[0051] Specifically, a bark-tearing mechanism 4 is provided on the outside of the device housing 1 at the end position for peeling the bark of the rootstock to form the grafting bag opening.

[0052] As can be seen, during use, the branch is inserted into the device housing 1 through the insertion channel 2. The first guiding mechanism 5 and the second guiding mechanism 6 guide and limit the inserted part of the branch. The cutting mechanism 8 cuts the inserted part. By continuously inserting the branch, the cut section of the branch is pushed into the device housing 1 by the subsequently inserted branch. The third guiding mechanism 7 continues to guide the section of the branch. During the pushing process, the second cutting mechanism 10 cuts a small section off the side of the section of the branch. By continuously pushing, the section of the branch is pushed until it is fully inserted. One end of the branch segment extends into the discharge window of the device housing 1. The first cutting mechanism 9 cuts a large arc-shaped bevel on the side of the branch segment. During the cutting process of the branch segment by the first cutting mechanism 9, the cutting mechanism 8 can cut off the subsequently inserted branches. After the branch segment is cut by the first cutting mechanism 9, the cut branch segment is continuously pushed and falls downward by the continuously inserted branches. After being guided by the scion discharge frame 41, it is discharged outward from the scion discharge window 3, thereby producing a scion for grafting.

[0053] The bark-tearing mechanism 4 can cut the mulberry bark, making it easier to tear the bark to form the grafting bag opening and to put or place the scion.

[0054] Specifically, the first guiding mechanism 5 includes a fixed ring frame 11, which is fixedly connected to the inner wall of the device housing 1. There are at least two fixed ring frames 11, which are arranged in parallel. Multiple first movable wheel sets 13 are arranged on the inner side of the fixed ring frame 11, and the multiple first movable wheel sets 13 are arranged in a ring array. The ends of the multiple first movable wheel sets 13 away from the fixed ring frame 11 extend to the inner side of the insertion channel 2. The second guiding mechanism 6 includes a fixed arc frame 12, which is fixedly connected to the inner wall of the device housing 1. There are two fixed arc frames 12, which are arranged symmetrically. A second movable wheel set 14 is arranged on the inner side of each of the two fixed arc frames 12. The third guiding mechanism 7 includes a third movable wheel set 15, which is connected to the inside of the device housing 1. There are two third movable wheel sets 15, which are arranged symmetrically.

[0055] It can be seen that the two fixed ring frames 11 and the multiple first movable wheel groups 13 in the ring array inside each fixed ring frame 11 can effectively limit the inserted branches, keeping the branches in the center. Thus, the second movable wheel groups 14 in the two subsequent fixed arc frames 12 can guide the inserted branches and the cut small branches. The two third movable wheel groups 15 limit the small branches, so that the first cutting mechanism 9 can quickly cut the small branches.

[0056] Furthermore, the first movable wheel group 13, the second movable wheel group 14, and the third movable wheel group 15 have the same structure. The first movable wheel group 13 includes a movable frame 16, one end of which is rotatably connected to a guide wheel 17, and the other end of which is provided with two connecting pins 18. A return spring 19 is provided between the two connecting pins 18, and one end of the return spring 19 is fixedly connected to the movable frame 16. The movable frame 16 in the first movable wheel group 13 is movably connected to the fixed ring frame 11 through the connecting pins 18. The movable frame 16 in the second movable wheel group 14 is movably connected to the fixed arc frame 12 through the connecting pins 18. The movable frame 16 in the third movable wheel group 15 is movably connected to the device housing 1 through the connecting pins 18.

[0057] It can be seen that when the first movable wheel group 13, the second movable wheel group 14, and the third movable wheel group 15 all come into contact with the branches or small sections of branches through the guide wheel 17, the branches or small sections of branches will drive the guide wheel 17 to move the movable frame 16 towards the return spring 19 and squeeze the return spring 19. When the return spring 19 is under force, it continuously applies an opposite force to the movable frame 16, thereby enabling the guide wheel 17 to remain in contact with the branches or small sections of branches, thus achieving the limitation of the branches or small sections of branches, and at the same time playing the role of clamping the branches or small sections of branches.

[0058] In order to enable the third movable wheel set 15 to drive the movement of the small branch, the third movable wheel set 15 also includes a follower frame 26 and a drive motor 27. A movable through groove 25 is provided on the first movable wheel set 13 at a position corresponding to one of the third movable wheel sets 15. The follower frame 26 is slidably connected inside the movable through groove 25. The lower end of the follower frame 26 extends to the outer side of the lower end of the first movable wheel set 13, and the upper end of the follower frame 26 extends to the outer side of the upper end of the first movable wheel set 13. The drive motor 27 is fixedly connected to the bottom of the follower frame 26. The output end of the drive motor 27 passes through the follower frame 26 and is fixedly connected to the guide wheel 17 in the third movable wheel set 15.

[0059] It can be seen that through the sliding connection between the follower frame 26 and the movable through slot 25, and the fixed connection between the drive motor 27 and the follower frame 26, the drive motor 27 can follow the movement when the guide wheel 17 in the third movable wheel group 15 contacts the small branch, which facilitates the drive motor 27 to drive the guide wheel 17. By starting the drive motor 27, the guide wheel 17 in the third movable wheel group 15 can be driven to rotate, thereby achieving the effect of conveying the small branch. In other embodiments, the drive motor 27 can be a commercially available motor with a self-locking function, so that when the drive motor 27 stops rotating, it cooperates with the guide wheel 17 in the third movable wheel group 15 to clamp the small branch, thereby achieving the fixing effect of the first cutting mechanism 9 on the small branch during the cutting process.

[0060] Furthermore, the rear end of the device housing 1 has reserved space for housing the battery and control board. All of the above electrical components are electrically connected to the control board and the battery. The control board can be a conventional known device such as a PLC control board, and the existing publicly available power connection technology will not be described in detail here.

[0061] Example 2:

[0062] The portable mulberry grafting device provided in Example 1 has been further optimized, specifically, as follows: Figure 6 As shown, the cutting mechanism 8 includes a fixed blade body 20 and a movable blade body 21, which are arranged opposite to each other. Each side of the fixed blade body 20 and the movable blade body 21 is provided with a cutting edge. The cutting edges of both the fixed blade body 20 and the movable blade body 21 are arc-shaped. The fixed blade body 20 is fixedly connected to the inner wall of the device housing 1. One end of the movable blade body 21 is rotatably connected to the device housing 1 through a connecting pin 22. The other end of the movable blade body 21 is provided with a first telescopic mechanism 23. The telescopic end of the first telescopic mechanism 23 is rotatably connected to the movable blade body 21, and the other end of the first telescopic mechanism 23 is rotatably connected to the device housing 1.

[0063] With the above structural design, after the branch extends into the device housing 1, when it is necessary to cut the branch, the first telescopic mechanism 23 is activated to push the movable blade 21 to rotate around the connecting pin 22 towards the fixed blade 20. Thus, the branch can be cut by the blades set in opposite directions by the fixed blade 20 and the movable blade 21. Through the arc-shaped setting of the blades and the cooperative design of the first guide mechanism 5 and the second guide mechanism 6, the displacement phenomenon during the branch cutting process can be effectively reduced, thereby facilitating subsequent cutting operations.

[0064] Example 3:

[0065] The portable mulberry grafting device provided in Example 1 has been further optimized, specifically, as follows: Figure 8 As shown, the first cutting mechanism 9 includes a cutting tool 28 and a second telescopic mechanism 32. Guide rails 29 are provided on both sides of the cutting tool 28. The guide rails 29 are fixedly connected to the inner wall of the device housing 1. The cutting tool 28 can slide along the length of the guide rails 29. An edge sealing frame 30 is fixedly connected to the guide rails 29. The edge sealing frame 30 is located inside the waste discharge window opened in the device housing 1. A connecting block 31 is fixedly connected to the outside of the cutting tool 28. The end of the connecting block 31 away from the cutting tool 28 extends to the outside of the device housing 1. The second telescopic mechanism 32 is fixed to the outside of the device housing 1. The telescopic end of the second telescopic mechanism 32 is fixedly connected to the connecting block 31.

[0066] With the above structural design, after the end of the small branch extends into the discharge window of the device housing 1, the second telescopic mechanism 32 is activated to push the connecting block 31 to move the cutting tool 28 into the discharge window. The movement of the cutting tool 28 is guided by the guide rail 29. The small branch is cut by the cutting tool 28 moving into the discharge window. The discharge window is sealed by the cutting tool 28 and the edge sealing frame 30. Thus, the cut debris can be directly discharged from the discharge window and prevented from falling back into the device housing 1.

[0067] Example 4:

[0068] The portable mulberry grafting device provided in Example 1 has been further optimized, specifically, as follows: Figure 9 and Figure 10 As shown, the peeling mechanism 4 includes a fixed base 33 and two peeling blades 34. The fixed base 33 is fixedly connected to the outside of the device housing 1. Two peeling blades 34 are arranged parallel inside the fixed base 33. Peeling blade seats 35 are fixedly connected to the two peeling blades 34 near the fixed base 33. The peeling blade seats 35 are located inside the fixed base 33. One peeling blade seat 35 is slidably connected to the fixed base 33, and the other peeling blade seat 35 is fixedly connected to the fixed base 33. Two adjusting rods 36 are arranged laterally inside the fixed base 33. The two adjusting rods 36 are located at both ends of the peeling blade seat 35, and both adjusting rods 36 are threadedly connected to the movable peeling blade seat 35. A transmission wheel 37 is fixedly connected to the outside of each of the two adjusting rods 36. The two transmission wheels 37 are connected to each other through a transmission component 38. One end of the adjusting rod 36 extends to the outside of the fixed base 33, and an adjusting knob 39 is fixedly connected to the end of the adjusting rod 36 located on the outside of the fixed base 33.

[0069] Through the above structural design, two bark-peeling blades 34 are used to cut the grafting area of ​​the mulberry rootstock. The distance between the two bark-peeling blades 34 can be adjusted by rotating the adjusting rod 36, thereby adjusting the bark-peeling width. Through the cooperation of the transmission wheel 37 and the transmission component 38, rotating one adjusting rod 36 causes the other to rotate accordingly, achieving synchronous rotation of the two adjusting rods 36 and effectively reducing the possibility of misalignment during the adjustment of the bark-peeling blades 34. The transmission wheel 37 and the transmission component 38 can be a chain and a toothed transmission disc or a grooved transmission belt, thus preventing slippage and idle rotation.
