Abstract
Description
Technical Field
[0001] This invention belongs to the field of grape grafting technology, specifically relating to a grape grafting training model. Background Technology
[0002] Grape grafting is a horticultural technique that involves grafting a branch (scion) of one grape variety onto a plant of another grape variety (rootstock), allowing them to heal and grow together to form a new plant. This technique is often used to improve grape varieties, enhance plant resistance to adverse conditions, improve fruit quality, or achieve rapid propagation.
[0003] Grape grafting training models are specialized equipment or tool combinations that assist grape grafting operations and improve grafting efficiency and survival rate. Their core functions revolve around key steps in the grafting process (such as rootstock fixing, scion cutting, precise docking, binding and fixing, etc.). Through mechanical structures, automated design or auxiliary tools, the difficulty of operation is reduced, making them particularly suitable for novice training or large-scale grafting scenarios.
[0004] Current grape grafting training models exhibit significant limitations in application. Because they are designed to be optimized only for specific grafting methods, they can only adapt to a single grafting technique in real-world production scenarios. This design results in a lack of necessary adjustment capabilities when faced with different grafting methods, ultimately leading to a narrow range of applicability and insufficient cross-scenario transferability.

[0019] 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.
[0020] Please see Figures 1-6 The present invention provides the following technical solution: a grape grafting training model, including a training shell 1, wherein the side surface of the training shell 1 is provided with a positioning component 2 for fixing the training model; The training housing 1 includes a first half-shell 11 and a second half-shell 12, a hinge 13 connecting the first half-shell 11 and the second half-shell 12 to achieve hinge, and a locking part 14 connecting the other side of the first half-shell 11 and the second half-shell 12 for locking. The top of the first half-shell 11 is provided with a first groove 3 for cutting the top of the grape stalk, and the top of the first half-shell 11 and the second half-shell 12 are respectively provided with a second groove 4 for cutting the top of the grape stalk. The side surface of the first half-shell 11 is provided with a bevel cutting component 5 for bevel cutting at the top.
[0021] Preferably, the depth of the first groove 3 and the second groove 4 is 2-3 cm, and the two sets of second grooves 4 are located at the middle of the top of the first half shell 11 and the second half shell 12, respectively, and the bottom of the second half shell 12 is set as a slope.
[0022] In practical use, the first groove 3 and the second groove 4 can be used to make grooves at the ends of grape branches and open the bark, so as to adapt to grafting methods such as bark grafting, bark grafting, terminal bud grafting, bark grafting, cleft grafting, and single bud grafting. Furthermore, the inclined surface set by the second half-shell 12 can be used to diagonally split grooves on the side surface of the grape stalk, thereby enabling training in both ventral grafting and cleft grafting methods.
[0023] Preferably, the locking part 14 includes a first mating block 141 connected to the side of the second half shell 12, a screw hole 142 opened on the surface of the first mating block 141, a locking screw 143 passing through the inside of the screw hole 142 and threadedly connected, a second mating block 144 connected to the side of the first half shell 11 near the second half shell 12, and a fixing hole 145 opened on the surface of the second mating block 144 and adapted to the size of the locking screw 143; After the first half-shell 11 and the second half-shell 12 are joined together, the second docking block 144 is located directly below the first docking block 141.
[0024] In practical use, the model can be fitted onto the surface of the grape stalk by setting the first half shell 11 and the second half shell 12, and the locking part 14 can be used to fix the first half shell 11 and the second half shell 12 together.
[0025] Preferably, the positioning assembly 2 includes a positioning housing 21 connected to the side surface of the second half-shell 12, a positioning part 22 mounted on the side surface of the positioning housing 21 and extending into the interior, and a first guide part 23 disposed between the positioning part 22 and the positioning housing 21 for guiding.
[0026] Preferably, the positioning part 22 includes a movable plate 221 disposed inside the positioning housing 21, a positioning rubber block 222 connected to the side surface of the movable plate 221, a first screw tube 223 that passes through and connects the movable plate 221 and the positioning rubber block 222, a bearing ring 224 that is fitted and installed on the side surface of the positioning housing 21, and a screw 225 that passes through and connects to the bearing ring 224 and is threadedly connected to the first screw tube 223.
[0027] In practical use, when the screw 225 rotates inside the bearing ring 224, it can drive the first screw tube 223 to move axially through the threaded connection. The axial movement of the first screw tube 223 can drive the positioning rubber block 222 to move closer to the first half shell 11 through the movable plate 221. When the positioning rubber block 222 presses against the inner grape stem surface, the position of the training model can be fixed on the grape stem surface.
[0028] Preferably, the first guide portion 23 includes first guide grooves 231 respectively opened on both sides of the positioning housing 21, and first guide blocks 232 respectively passing through the interior of the two sets of first guide grooves 231 and connected to both sides of the movable plate 221.
[0029] In practical use, when the movable plate 221 is subjected to a force, it can drive the first guide block 232 to slide inside the first guide groove 231, which can limit the movement direction of the movable plate 221 and maintain the stability of the movement.
[0030] Preferably, the beveled component 5 includes a beveled portion 51 disposed on the outer surface of the first half-shell 11, and an adjustment portion 52 and a second guide portion 53 disposed between the beveled portion 51 and the first half-shell 11. The oblique cut portion 51 includes an oblique arc plate 511 disposed on the outer surface of the first half shell 11, a third groove 512 opened on the top of the oblique arc plate 511, and an auxiliary groove 513 opened on the top of the oblique arc plate 511 and adapted to the first groove 3 and the second groove 4 on the top of the first half shell 11. The depth of the third groove 512 is 2-3 cm.
[0031] In practical use, the end of the grape stalk can be cut into a bevel by setting the top bevel of the beveled arc plate 511, so as to be suitable for training in grafting methods. Furthermore, the third groove 512 allows for cutting on the side surface of the middle part of the grape stem, which is suitable for training with tongue grafting.
[0032] Preferably, the adjustment part 52 includes a second helical tube 521 connected to the outer surface of the oblique arc plate 511, a bearing seat 522 installed on the outer surface of the first half shell 11, and a third screw 523 that passes through and is connected to the inside of the bearing seat 522 and threadedly connected to the second helical tube 521.
[0033] In practical use, when the third screw 523 rotates inside the bearing seat 522, it can drive the second screw tube 521 to move longitudinally through the threaded connection. The longitudinal movement of the second screw tube 521 can drive the oblique arc plate 511 to move longitudinally. The oblique arc plate 511 cuts the top of the grape stalk into an oblique surface, thereby adjusting the position of the oblique arc plate 511.
[0034] Preferably, the second guide portion 53 includes a second guide groove 531 formed on the surface of the beveled arc plate 511, and a second guide block 532 passing through the interior of the second guide groove 531 and connected to the outer surface of the first half-shell 11. It should be noted that the angle range of the beveled top surface of the beveled arc plate 511 is 40°-50°.
[0035] In practical use, when the obliquely cut arc plate 511 is subjected to a force, it can drive the second guide groove 531 to slide on the surface of the second guide block 532, which can limit the movement direction of the obliquely cut arc plate 511 and maintain the stability of the movement.
[0036] Preferably, the side surface of the first half-shell 11 is provided with a side-cutting component 6 for grafting grape stem sidewalls. The side-cutting component 6 includes a side-cutting groove 61 formed on the side surface of the first half-shell 11, and a transverse cutting groove 62 formed on the side surface of the first half-shell 11 and located directly below the side-cutting groove 61. It should be noted that the side-cutting angle of the side-cutting groove 61 is controlled within the range of 30°-45°.
[0037] In practical use, the side cutting groove 61 can be used to cut the side surface of the middle part of the grape stem, and the horizontal cutting groove 62 can be used to cut the bottom surface of the cut so that the bark at that position can be removed. This can be adapted to the training of inlay budding and square budding grafting methods.
[0038] Example 1: Working principle: When grafting the ends of grape stalks, firstly, with the first half-shell 11 and the second half-shell 12 joined and locked, the first half-shell 11 and the second half-shell 12 can be fitted onto the cut of the grape stalk, keeping the ends flush. Then, the screw 225 can be rotated. When the screw 225 rotates, it drives the first screw tube 223 to move axially. When the first screw tube 223 moves axially, it drives the positioning rubber block 222 to move closer to the grape stalk through the movable plate 221. When the positioning rubber block 222 is pressed against the surface of the grape stalk, the first half-shell 11 and the second half-shell 12 can be fixed to the surface of the grape stalk. Then, the top of the grape stalk can be slotted by the first groove 3 and the second groove 4 set on the top of the first half-shell 11 and the second half-shell 12, and the bark at the end of the grape stalk can also be cut open to adapt to grafting methods such as bark grafting, bark-attached grafting, terminal bud grafting, bark grafting, cleft grafting, and single bud cleft grafting.
[0039] Example 2: Working principle: When grafting the middle part of a grape stalk, first unfold the first half shell 11 and the second half shell 12, then put the first half shell 11 and the second half shell 12 on the grape stalk to be grafted. After closing the first half shell 11 and the second half shell 12, align the screw hole 142 with the fixing hole 145. Then rotate the locking screw 143. When the locking screw 143 rotates inside the screw hole 142, it can move downward. When the locking screw 143 moves into the fixing hole 145, the first half shell 11 and the second half shell 12 can be closed and fixed. Then the first half shell 11 and the second half shell 12 can be fixed to the surface of the grape stalk by the positioning component 2. Then, when the third screw 523 rotates, it drives the second screw tube 521 to move longitudinally. When the second screw tube 521 moves longitudinally, it drives the oblique arc plate 511 to move longitudinally. The oblique arc plate 511 cuts the top of the grape stalk into an oblique surface, so that the end of the grape stalk can be trained in the joining and tongue grafting methods. At the same time, the epidermis of the middle side surface of the grape stem can be cut and removed by the side-cutting component 6, so as to realize the training of inlay bud grafting and square bud grafting methods; By setting the bottom slope of the second half-shell 12, a groove can be cut on the middle side surface of the grape stalk, thereby enabling training in both ventral grafting and cleft grafting methods.
[0040] It should be noted that when grafting by bark grafting, make a cut in the bark of the rootstock by setting the first groove 3 or the second groove 4, loosen the bark, make a diagonal cut on the back of the scion bud, and then make a horizontal cut below the bud to remove the bark. Insert the scion into the back of the cut on the rootstock, slightly exposing the white part, and then completely seal and wrap it, leaving only the bud eye exposed. When grafting by bark grafting, make a cut in the bark of the rootstock by setting the first groove 3 or the second groove 4 and loosen it. After making a slanted cut on the back of the scion bud, make a short cut on the back and lightly remove a small amount of bark from the side. Insert the scion into the cut of the rootstock, with the bark showing a little white, and then wrap it completely. When grafting by apical bud grafting, make a slanted cut to one-third of the depth at the top of the rootstock by setting the first groove 3 or the second groove 4. Obtain the scion with buds in the same way. When grafting, if the scion is smaller than the cut of the rootstock, align the cambium layers on one side. Wrap it so that it is not ventilated or permeable to water. When grafting by bark grafting, make a 2-3 cm circumference cut on the smooth part of the rootstock, then make a straight cut on the rootstock with the horizontal groove 62 set to the wood, pry open the bark, carefully loosen the bark when taking the scion to avoid damaging the bud, put the bark of the scion into the rootstock, align the lower ends, and wrap the exposed buds and petioles. When grafting by cleft grafting, two sets of second cuts 4 are set in the center of the rootstock to cut and expose the insertion seam. The scion bud is sharpened on both sides, ensuring that one side of the bud is slightly thicker. The small bud of the scion is aligned with the cambium layer of the rootstock, and the cut is slightly exposed. It is then wrapped to prevent rainwater and air from entering. When grafting by single bud cleft grafting, make a cut at one-quarter of the cross-section of the rootstock through the setting of two sets of first cut grooves 3, and then make an oblique cut 2 cm below the cut surface to remove the removed part; make a cut 2.5 cm deep from the back of the bud into the xylem of the scion, and then make an oblique cut on the back of the base, cut off at the top of the bud, insert the scion with at least one side aligned with the cambium of the rootstock, and wrap it. When grafting by side grafting, a notch is cut on the rootstock and the bark is pried open by making a straight cut below the notch through the second groove 4. The scion is prepared in a similar way to the bark-in grafting, inserted into the bark below the notch, and the exposed bud and petiole are wrapped. When grafting by cleft grafting, make a slanted cut on the smooth part of the rootstock through the side cut groove 61, reaching one-third of the xylem and about 2 cm in length; make a cut on each side of the scion, with the bud side slightly thicker and the other side slightly thinner, inserting it with the cambium layer of one side of the bud aligned, and wrap the exposed bud and petiole. When grafting by inlay budding, make a long cut about 2.5 cm deep into the wood by setting the horizontal cutting groove 62 on the rootstock, and then make a diagonal cut below it by using the side cutting groove 61 to remove the shavings; the scion is prepared by cutting the bud in the same way, inserted into the incision in the rootstock, and the exposed bud eye is completely sealed and wrapped. When grafting using the square budding method, the rootstock preparation method is similar to that of the budding method. Square lines are carved around the bud, and the bud patch is taken out with the same length as the cut surface of the rootstock. The scion bud patch is placed inside the bark of the rootstock and completely sealed, leaving only the bud eye exposed. When grafting by cladding, select branches of the same thickness for both the scion and the rootstock. The top of the rootstock is cut into a horse ear shape by setting the oblique cut 51 at the top, and the bottom of the scion is also cut into a horse ear shape. The cut surfaces are of equal length. The two cut surfaces are placed together and aligned, and the exposed buds are wrapped. When grafting by tongue grafting, the top of the rootstock is cut into a slant by setting the slant at the top of the slant cut 51. Then, two sets of second cut grooves 4 are set to make a straight cut on the slant to form an incision. The bottom of the scion is also cut into a slant and then made into an incision. The two incisions are interlocked until the slants are aligned and the bud is wrapped.
[0041] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
