Technical Field

[0001] This utility model relates to the field of tree grafting technology, specifically to a tree grafting fixing device. Background Technology

[0002] Top grafting, also known as high-position grafting or top grafting for variety replacement, is a common technique in fruit tree horticulture. It refers to grafting onto a mature tree at a higher position (such as on the trunk, main branches, or lateral branches) with the aim of completely replacing the variety of the crown.

[0003] Chinese Patent No. CN206314253U discloses a fixing device for top grafting of fruit trees, including a first arc-shaped fixing plate, a second arc-shaped fixing plate, a hinge, a fixing hook, a fixing ring, a positioning ring, and a support rod. One side of the first and second arc-shaped fixing plates is connected by the hinge, and the other side is respectively provided with a fixing hook and a fixing ring, with each fixing hook and fixing ring corresponding to the other. Positioning rings are provided on the outer walls of both the first and second arc-shaped fixing plates, and the support rod is inserted into the positioning ring. The beneficial effect of this invention is that it can effectively position the top grafted branches, prevent wind damage, and improve the grafting success rate.

[0004] However, in the above technical solution, the tree is supported and positioned by multiple positioning rings on the support rod. However, during its use, not only the trunk will grow, but the grafted branches will also grow. If the positioning rings are not replaced or removed in time, it will affect the growth of the branches. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a tree grafting and fixing device.

[0006] The technical solution of this utility model is as follows: A tree grafting fixing device includes two arc-shaped plates symmetrically arranged, with one end of the two arc-shaped plates rotatably connected. The arc-shaped plates are detachably connected by biodegradable cable ties. Multiple arc-shaped blocks are connected to each arc-shaped plate, and multiple receiving grooves are opened on the arc-shaped blocks. Multiple support components are distributed and connected to the arc-shaped plates. The support components consist of support rods and fixing rings. The support rods are detachably connected to the receiving grooves. Multiple fixing rings are distributed along the axis of the support rods, and the fixing rings are provided with pre-fabricated stress concentration structures.

[0007] Preferably, the fixing ring consists of two arc-shaped rings, with a connecting piece integrally formed between the arc-shaped rings, the thickness of which is less than the thickness of the arc-shaped rings.

[0008] Preferably, one end of the support rod is integrally formed with two elastic latches, which engage with the receiving groove.

[0009] Preferably, the inner wall of the arc-shaped plate is connected with a plurality of first elastic strips, and the inner wall of the fixing ring is connected with a plurality of second elastic strips.

[0010] Preferably, the support rod, retaining ring, and elastic latch are all made of polylactic acid.

[0011] Preferably, the support rod, fixing ring, and elastic tab degrade faster than biodegradable cable ties.

[0012] Preferably, the curved plate is provided with a label area for identifying the grafting date or variety.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, a support assembly is used to fix and support the grafted branches. All components within the support assembly are made of biodegradable polylactic acid. The stress concentration structure between the fixing rings used to restrict the branches can break as the branches grow, thus avoiding affecting their normal growth. The arc-shaped plate used to connect with the trunk can also decouple the overall structure from the tree through the degradation of the biodegradable cable ties. By using different degradation rates, the fixation function is achieved, the impact on the growth of the branches is avoided, and the need for subsequent manual intervention is reduced.

[0020] Example 1

[0021] like Figures 1-4As shown, the present invention proposes a tree grafting fixing device, comprising an arc-shaped plate 1, an arc-shaped block 2, and a support assembly. Two arc-shaped plates 1 are symmetrically arranged, with one end of the two arc-shaped plates 1 rotatably connected. The arc-shaped plates 1 are detachably connected to each other by a biodegradable cable tie. Multiple arc-shaped blocks 2 are connected to each arc-shaped plate 1, and multiple receiving grooves 3 are provided on the arc-shaped blocks 2. The receiving grooves 3 are all convex or stepped, and cooperate with the elastic latches 8 through the stepped protrusions. Multiple support assemblies are distributed around the central axis of the arc-shaped plate 1. The support assembly is connected to the arc-shaped plate 1 and consists of a support rod 4 and a fixing ring 5. The support rod 4 is detachably connected to the receiving groove 3. Multiple fixing rings 5 ​​are distributed along the axial direction of the support rod 4, and the fixing rings 5 ​​are provided with a pre-fabricated stress concentration structure.

[0022] Example 2

[0023] like Figures 2-4 As shown, this utility model proposes a tree grafting fixing device. Compared with Embodiment 1, this embodiment describes the detailed structure of the support component.

[0024] In an optional embodiment, the fixing ring 5 consists of two arc-shaped rings 6, with a connecting piece 7 integrally formed between the arc-shaped rings 6. The thickness of the connecting piece 7 is less than the thickness of the arc-shaped rings 6. The connecting piece 7 is prone to breakage under certain external force, thereby causing the two arc-shaped rings 6 to separate from each other, preventing the binding from forming a cage that affects tree growth.

[0025] In an optional embodiment, the support rod 4 has two elastic latches 8 integrally formed at one end, which engage with the receiving groove 3; the elastic latches 8 facilitate insertion and engagement with the receiving groove 3 through their elastic deformation.

[0026] In an optional embodiment, a plurality of first elastic strips 9 are connected to the inner wall of the arc plate 1, and a plurality of second elastic strips 10 are connected to the inner wall of the fixing ring 5; the first elastic strips 9 and the second elastic strips 10 are both rubber or other elastic materials, which can deform and fit against the outer wall of the tree when in contact with it.

[0027] In an optional embodiment, the support rod 4, the retaining ring 5, and the elastic latch 8 are all made of polylactic acid (PLA); PLA can degrade in outdoor environments within months or years and can be technically removed as the tree grows to avoid affecting its growth.

[0028] In an optional embodiment, the support rod 4, the fixing ring 5, and the elastic latch 8 degrade faster than the biodegradable cable tie; if the biodegradable cable tie degrades faster than the support assembly, it may be damaged when it falls and comes into contact with tree branches. This situation can be avoided if the components of the support assembly degrade faster than the cable tie.

[0029] In an optional embodiment, the curved plate 1 is provided with a label area 11 for identifying the grafting date or variety; the label area 11 makes it convenient for staff to affix labels for later recording and observation.

[0030] In summary, when using this utility model, the work involves grafting branches onto the trunk of a fruit tree, then wrapping the branches and trunk with plastic wrap to retain moisture and prevent evaporation. Next, two arc-shaped plates 1 are fitted onto the outside of the trunk, and biodegradable cable ties are used to connect the two through the connection holes on the arc-shaped plates 1. Simultaneously, the presence of the first elastic strip 9 maintains a certain distance between the arc-shaped plates 1 and the trunk to prevent excessive clamping that could affect tree growth. Furthermore, the number of support rods 4 is adjusted according to the number of grafted branches. After inserting one end of the support rod 4 into the receiving groove 3, the elastic latch 8 engages with the side wall of the receiving groove 3. The protruding contacts engage to restrict movement between the two components. As the support rod 4 is inserted, the branch passes through the fixing ring 5 to create a positioning effect. The second elastic strip 10 on the fixing ring 5 can fit into the irregularly shaped branch. As the branch continues to grow, both the biodegradable cable tie and the support component gradually degrade. The support component degrades faster than the biodegradable cable tie due to its material. At the same time, as the branch thickens, it comes into contact with the fixing ring 5, gradually opening it and causing it to break off from the connecting piece 7. This prevents excessive restriction from causing deformation during growth. After degradation, the above structure detaches from the tree to reduce the impact on tree growth.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
