Description

Technical Field

[0001] This invention relates to the field of grafting binding devices, and more specifically to a grafting binding device for tree plants. Background Technology

[0002] Grafting methods are broadly divided into two types: branch grafting and bud grafting. Branch grafting is carried out in early spring before the buds become active. Trees have cambium tissue under the bark that forms new cells. The new cells are tightly attached together, forming new tissue in sequence.

[0003] The requirements for grafting are: the surfaces that are in close contact need to be flat, the cambium layers need to be in contact, the cambium layers need to be tightly attached together, and they need to be firmly bound together with biodegradable polyethylene tape. Before they are completely glued together, moisture must be kept away from this part.

[0004] The work of binding the grafting part is quite troublesome. When the tape is wrapped around the grafting part, the hands must be switched once. The staff has to loosen their grip on the grafting part, which causes the grafting part to shift and misalign after binding, and the cambium cannot be aligned, affecting the grafting effect. Summary of the Invention

[0005] The purpose of this invention is to provide a grafting device for tree plants, which solves the problem that grafting requires two hands and lacks hand-held fixation of the branch parts, resulting in displacement and misalignment of the grafted parts and misalignment of the cambium layers after binding.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A grafting and binding device for tree plants, characterized in that it comprises: a tape retainer, including a damping shaft for inserting tape and a hollow wheel for driving the damping shaft to perform a circular motion around the branch, wherein one end of the tape is attached to the branch and, during the circular motion, the damping shaft releases the tape and maintains the tension of the tape; a housing, including a handle-shaped gripping part and a wheel retaining part for constraining the hollow wheel to rotate around its own axis, wherein the side of the wheel retaining part facing the center of the hollow wheel is open; a driver, disposed inside the housing, wherein the actuator of the driver is drively connected to the hollow wheel; and a power supply, electrically connected to the driver via a switch.

[0008] Furthermore, the rotating wheel retaining part and one side of the hollow rotating wheel are provided with an opening with a central angle of less than 180°.

[0009] Furthermore, the hollow wheel has two hooks at one end near its opening, and the openings of the two hooks face away from the axis of the hollow wheel. The two ends of the damping shaft are respectively inserted into the two hooks and cannot be rotated. The tape is located between the two hooks.

[0010] Furthermore, the damping shaft includes: a first retainer connected to one end of the hollow wheel along its axial direction; a second retainer connected to the other end of the hollow wheel along its axial direction; a pin rotatably connected to the first retainer via a bearing, the pin being elastic and having an interference fit with the shaft hole of the tape; and a friction disc slidably connected to the second retainer via a guide rod and elastically connected to the second retainer via an elastic element, the friction disc being able to move along its own axis but not rotate, the elastic element having an internal force that drives the friction disc closer to the pin.

[0011] Furthermore, a bolt is installed at the end of the insertion post facing the first card holder, and the first card holder is provided with a through hole that is clearance-fitted with the bolt. The diameter of the bolt head is larger than the diameter of the through hole, and the distance between the bolt head and the first card holder is smaller than the axial length of the bearing.

[0012] Furthermore, the friction disc and the guide rod are an integral piece, and the guide rod is prism-shaped; the elastic element is a spring sheet, and the two ends of the spring sheet are bonded to the friction disc and the second card holder.

[0013] Furthermore, both the hollow wheel and the wheel retaining part have C-shaped cross sections, and the side facing its own center is open. The wheel retaining part is in rolling friction contact or sliding friction contact with the two end faces and the outer peripheral surface of the hollow wheel.

[0014] Furthermore, the wheel retaining part contacts the outer peripheral surface of the hollow wheel through a roller shaft, the two ends of which are rotatably connected to the housing, and the axis of the roller shaft is parallel to the axis of the hollow wheel; the wheel retaining part contacts the two end faces of the hollow wheel through wear-resistant plates, and the wear-resistant plates are fixedly connected to the two end faces of the hollow wheel.

[0015] Furthermore, the driver is a hub motor, and the outer peripheral surface of the driver is covered with a friction layer, which contacts the outer peripheral surface of the hollow wheel.

[0016] Furthermore, the friction layer is leather.

[0017] Compared with the prior art, this application has the following advantages:

[0018] A grafting and binding device for tree plants is provided. After a hollow rotating wheel is fitted onto a branch and one end of tape is attached to the branch, turning on the switch will automatically drive the tape to rotate around the branch to bind the branch. After that, it can be operated with only one hand, and the operator's other hand can be used to hold and fix the grafted part to avoid misalignment during the binding process.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0029] Because binding the grafting site is quite troublesome, the tape must be switched hands once it is wrapped around the grafting site. The staff has to loosen their grip on the grafting site, which causes the grafting site to shift and misalign after binding, and the cambium layers cannot be aligned, affecting the grafting effect.

[0030] To address the aforementioned issues, a grafting and binding device for tree plants is provided below. Please refer to [reference needed]. Figure 1 , 2 3.

[0031] Tree grafting binding devices include:

[0032] The tape retainer includes a damping shaft 1 for inserting tape 9 and a hollow wheel 2 for driving the damping shaft 1 to perform a circular motion around a tree branch. During the circular motion, one end of the tape 9 is attached to the tree branch, and the damping shaft 1 releases the tape 9 with appropriate tension, so that the tape 9 can be firmly bound to the tree branch with a certain tension.

[0033] The housing includes a straight handle-shaped grip 3 and a wheel retainer 4 that constrains the hollow wheel 2 to rotate around its own axis. The side of the wheel retainer 4 facing the center of the hollow wheel 2 is open, and the tape 9 can be released from the damping shaft 1 onto the branch without obstruction.

[0034] The driver 5 is located inside the housing, and the actuator of the driver 5 is connected to the hollow rotary wheel 2 for transmission.

[0035] The power supply 6 is located inside the housing and is electrically connected to the driver 5 via a switch 7.

[0036] The working principle of the above embodiments is as follows:

[0037] The worker places the hollow rotating wheel 2 onto the tree branch and attaches one end of the tape 9 to the branch. After turning on the switch 7 and powering on the driver 5, the hollow rotating wheel 2 rotates. As the tape 9 moves in a circular motion around the branch, the damping shaft 1 releases the tape 9 with appropriate tension, allowing the tape 9 to be firmly bound to the branch. The worker moves the handle along the length of the branch at an appropriate speed, thus binding the two branches together with the tape 9.

[0038] When the branch is higher than the worker's shoulder, it is difficult to move the hollow wheel 2 upward to remove it from the branch after tying it. However, this embodiment solves this problem simply by providing an opening 8 with a central angle of less than 180° on one side of the wheel holding part 4 and the hollow wheel 2. The branch can enter or leave the interior of the hollow wheel 2 through the opening 8, and the hollow wheel 2 will not detach from the wheel holding part 4 when it rotates around its own center.

[0039] Both the hollow wheel 2 and the wheel retaining part 4 have C-shaped cross sections, and the side facing their own center is open. The wheel retaining part 4 makes rolling friction contact or sliding friction contact with the two end faces and the outer peripheral surface of the hollow wheel 2 to keep the axis of the hollow wheel 2 coincide with its own axis and to restrict the axial movement of the hollow wheel 2.

[0040] For details, please refer to Figure 3 and Figure 5 .

[0041] The rotating wheel holding part 4 contacts the outer peripheral surface of the hollow rotating wheel 2 through the roller 41. The two ends of the roller 41 are rotatably connected to the housing, and the axis of the roller 41 is parallel to the axis of the hollow rotating wheel 2.

[0042] The wheel retaining part 4 contacts the two end faces of the hollow wheel 2 through the wear-resistant plate 21, and the wear-resistant plate 21 is fixedly connected to the two end faces of the hollow wheel 2.

[0043] The driver 5 uses a hub motor. The outer peripheral surface of the driver 5 is covered with a friction layer, which contacts the outer peripheral surface of the hollow wheel 2. The friction layer can be made of leather.

[0044] In the above embodiment, the outer peripheral surface of the hollow wheel 2 is flat.

[0045] The outer circumferential surface of the hollow wheel 2 can also be designed as a toothed surface. Accordingly, gears need to be used to replace the roller shaft 41, and gear rings need to be used to replace the friction layer.

[0046] On the other hand, please refer to Figure 5 .

[0047] Damping shaft 1 includes coaxially arranged:

[0048] The first card holder 11 is connected to one end of the hollow rotating wheel 2 along its axial direction;

[0049] The second card holder 14 is connected to the other end of the hollow rotating wheel 2 along the axial direction;

[0050] The insert 12 is connected to the first card holder 11 via the bearing 13. The insert 12 can rotate around its own axis. The insert 12 is elastic and has an interference fit with the shaft hole of the tape 9.

[0051] The friction disc 15 is connected to the second card holder 14 via the guide rod 16 and the elastic element 17. The friction disc 15 can move along its own axis but cannot rotate. The elastic element 17 has an internal force that drives the friction disc 15 to approach the insertion post 12.

[0052] The end of the friction disc 15 facing the insertion post 12 has a convex spherical surface, and the end of the insertion post 12 facing the friction disc 15 has a concave spherical surface. The two are resisted by the elastic force of the elastic element 17 to generate rotational damping, and the tape 9 is tensioned by the rotational damping of the insertion post 12.

[0053] The first retainer 11, the bearing 13, and the insert 12 are a single assembly. To prevent the three from separating, a bolt 18 is installed on the end of the insert 12 facing the first retainer 11. The first retainer 11 is provided with a through hole 111 that is clearance-fitted with the bolt 18. The diameter of the bolt head is larger than the diameter of the through hole 111, and the distance between the bolt head and the first retainer 11 is less than the axial length of the bearing 13.

[0054] After the damping shaft 1 is assembled, the bolt 18 and the first retainer 11 never come into contact. When the damping shaft 1 is removed, the head of the bolt 18 abuts against the side of the first retainer 11 away from the insert post 12, thereby preventing relative axial movement between the first retainer 11 and the insert post 12.

[0055] The friction disc 15 and the guide rod 16 are a single piece. The guide rod 16 is prismatic in shape. The elastic element 17 is a spring sheet, and both ends of the spring sheet are bonded to the friction disc 15 and the second retainer 14. When the damping shaft 1 is removed, the internal force of the elastic element 17 is released and it elongates. However, the maximum axial length of the elastic element 17 is less than the axial length of the guide rod 16, thereby preventing the axial movement of the friction disc 15 and the second retainer 14.

[0056] On the other hand, please refer to Figure 6 .

[0057] Two hooks 22 are provided at one end of the hollow wheel 2 near its own opening 8. The openings 8 of the two hooks 22 are both facing away from the axis of the hollow wheel 2. The two ends of the damping shaft 1 are respectively inserted into the interior of the two hooks 22, and the tape 9 is located between the two hooks 22.

[0058] Because the tape 9 is always under tension when binding the tree branch, the tape 9 and the damping shaft 1 are always subjected to a pulling force that moves toward the center of the hollow wheel 2, thereby preventing the hook 22 and the damping shaft 1 from separating.

[0059] It should be noted that, in order to prevent the damping force inside the damping shaft 1 from being lost due to relative movement between the damping shaft 1 and the hook 22, the two ends of the damping shaft 1 are non-rotatably connected to the hook 22.

[0060] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of the embodiments of the present invention.
