Description

Technical Field

[0001] The utility model relates to the technical field of grafting, in particular to a portable device for grafting Torreya grandis 'Merrillii' seedlings with Torreya grandis Background Art

[0002] Grafting is a propagation method in which a bud or branch of one plant is grafted onto another plant so that the two joined parts grow into a complete plant. The bud or branch grafted on is called the scion, and the plant to be grafted is called the rootstock. The key to successful grafting is to closely combine the cambiums of the scion and the rootstock. Grafting methods are divided into branch grafting and bud grafting, and grafting is carried out by utilizing the wound healing function of plants. Traditionally, grafting is carried out by manually cutting the grafting body (rootstock), then cutting the end of the scion (grafting branch) into a wedge shape, and then inserting the grafting branch into the cut grafting body to closely combine the cambiums of the scion and the rootstock. Finally, they are wound together with a transparent film to fasten the scion and the rootstock together, which can also achieve the purpose of preventing water loss and improving the survival rate. However, the traditional method of manually inserting the scion into the rootstock is not very stable (prone to skew), and cannot closely combine the cambiums of the scion and the rootstock. Therefore, the survival rate depends entirely on the experience and skills of the grafter. Moreover, in the traditional manual grafting method, when winding the transparent film, the connection part between the scion and the rootstock will also loosen and shift, which will further reduce the probability of closely combining the cambiums of the scion and the rootstock, and thus further reduce the survival rate of grafting, which is not conducive to the large-scale popularization of Torreya grandis grafting.

[0003] Chinese Utility Model Patent CN 218417461 U discloses a fruit tree grafting device, which includes a fixed frame and an airbag; there are two fixed frames and they are symmetrically distributed. The airbags are fixedly distributed inside the two fixed frames, and an inflation nozzle is provided outside the airbag and extends to the outside of the fixed frame. This device has complex operation and is not conducive to the efficient grafting of fruit trees. Summary of the Utility Model

[0004] The utility model aims to solve the above-mentioned shortcomings of the prior art and provides a portable device for grafting Torreya grandis branches on Torreya grandis seedlings, which can graft Torreya grandis branches on Torreya grandis seedlings quickly, conveniently and with a high success rate, meeting the requirements of Torreya grandis grafting for increasing yield, being quick, convenient and having a high success rate.

[0005] The technical solution adopted by the utility model to solve its technical problems: This portable device for grafting Torreya grandis seedlings with Torreya grandis includes a vertical plate. Suspension blocks are fixed at both the top and bottom of the vertical plate. Longitudinal perforations are opened on both suspension blocks, and clamping members are installed in both longitudinal perforations; The clamping member includes clamping plates arranged oppositely. On both clamping plates, there are "V"-shaped and symmetrically arranged clamping openings. On both clamping plates, insertion rods inserted into the suspension blocks are fixed. At the end of each insertion rod, a limiting block with a cross-section larger than that of the insertion rod is fixed. Compression springs for making the two clamping plates approach each other are installed on each insertion rod. Handle screws threadedly connected to the suspension block are provided at the relative positions of the two clamping openings; Rubber soft pads are fixed on the clamping surfaces of the two clamping openings. The function of the lower-side suspension block here is to stably clamp the rootstock, and the upper-side suspension block is used to stably clamp the scion and stably and accurately graft the Torreya grandis branch onto the Torreya grandis seedling; The functions of the clamping plate, clamping opening, insertion rod, and compression spring here are to provide a clamping force to clamp the Torreya grandis seedling and the Torreya grandis branch, so as to easily insert the Torreya grandis branch onto the Torreya grandis seedling; The function of the limiting block here is to create a certain gap between the two clamping plates, preventing the two clamping plates from fitting together under the elastic force of the compression spring, providing a smooth channel for the subsequent clamping of the Torreya grandis seedling and the Torreya grandis branch; The function of the handle screw here is that after the clamping opening clamps the Torreya grandis seedling, it can be tightened by the handle screw to avoid the device from shaking, and it can also tighten the Torreya grandis branch when the Torreya grandis branch is grafted onto the Torreya grandis seedling, thus avoiding the problem of the position deviation of the Torreya grandis branch after being grafted onto the Torreya grandis seedling, resulting in an unsmooth nutrient channel and a low survival rate, for the convenience of subsequent winding of the transparent film; The function of the rubber soft pad here is to make the clamping of the Torreya grandis seedling and the Torreya grandis branch a flexible clamping, avoiding scratching the surfaces of the Torreya grandis seedling or the Torreya grandis branch; The "V" shape of the clamping opening here can adapt to Torreya grandis seedlings and Torreya grandis branches with different diameters.

[0006] For further improvement, a folding cover plate is installed between the clamping plate and the suspension block. The function of the folding cover plate here is to prevent soil and dirt from touching the insertion rod and the compression spring, thus affecting the operation of the compression spring.

[0007] For further improvement, self-lubricating layers are provided at both side ends of each clamping plate. The function of the self-lubricating layer here is to make the clamping plate move more smoothly and prevent jamming; The self-lubricating layer is made of tin bronze material.

[0008] For further improvement, a "V"-shaped flared opening is provided at the inlet end of the longitudinal perforation. The function of the flared opening here is to facilitate guiding the device to be inserted into the Torreya grandis seedling and guiding the Torreya grandis branch to be inserted into the clamping opening.

[0009] For further improvement, a set of rolling columns are provided on the opposite surfaces of the two clamping plates. The function of the rolling columns here is to make it a rolling friction when the Torreya grandis seedling and the Torreya grandis branch are inserted into the clamping opening, which can reduce the scratching of the surfaces of the Torreya grandis seedling and the Torreya grandis branch and improve the survival rate (such as Figure 5 、Figure 6 as shown

[0010] Furthermore, an installation base is installed on the lower side suspension block, and three support feet arranged at equal angles are installed on the installation base by means of threads. The bottom ends of the support feet are threadedly connected with adjusting rods, and the bottom ends of the adjusting rods are pointed tips. The functions of the installation base, the support feet, and the adjusting rods here are to be utilized when grafting onto large torreya grandis saplings. The adjusting rods can adjust the length, so as to play a role in stabilizing the placement of the device (as Figure 8 shown

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1). Through the clamping plates, the clamping mouths, the insertion rods, and the compression springs, clamping force can be provided to clamp the torreya grandis saplings and the torreya grandis branches, so that it is easy to operate to insert the torreya grandis branches onto the torreya grandis saplings;

[0013] 2). Through the limiting blocks, a certain gap is generated between the two clamping plates, and the two clamping plates will not be mutually attached under the elastic force of the compression springs, providing a smooth passage for the subsequent clamping of the torreya grandis saplings and the torreya grandis branches;

[0014] 3). Through the handle screws, after the clamping mouths clamp the torreya grandis saplings, they can be tightened by the handle screws, so as to avoid the shaking of the device, and can also tighten the torreya grandis branches when the torreya grandis branches are grafted onto the torreya grandis saplings, so as to avoid the problem of the position deviation of the torreya grandis branches after being grafted onto the torreya grandis saplings, resulting in unsmooth nutrient channels and low survival rate, for the convenience of subsequent winding of the transparent film;

[0015] 4). Through the rubber soft pads, the clamping of the torreya grandis saplings and the torreya grandis branches can be flexibly tightened, avoiding scratching the surfaces of the torreya grandis saplings or the torreya grandis branches. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] The present utility model will be further described below in conjunction with the accompanying drawings:

[0026] Referring to the accompanying drawings: This portable device for grafting torreya grandis saplings with torreya grandis branches includes a vertical plate 1. Suspension blocks 2 are fixed to both the top and bottom of the vertical plate 1. Longitudinal through holes 2-1 are formed in both suspension blocks 2, and clamping members 3 are installed in both longitudinal through holes 2-1; The clamping member 3 includes clamping plates 3-1 arranged oppositely. Clamping openings 3-1a in the shape of "V" and symmetrically arranged are provided on both clamping plates 3-1. Insertion rods 3-3 inserted into the suspension blocks 2 are fixed to both clamping plates 3-1. Limit blocks 3-3a with a cross-section larger than that of the insertion rods 3-3 are fixed to the ends of the respective insertion rods 3-3. Compression springs 3-4 for making the two clamping plates 3-1 approach each other are installed on the respective insertion rods 3-3. Handle screws 3-5 threadedly connected to the suspension blocks 2 are provided at the relative positions of the two clamping openings 3-1a; Rubber soft pads 3-6 are fixed to the clamping surfaces of the two clamping openings 3-1a.

[0027] A folding cover plate 4 is installed between the clamping plate 3-1 and the suspension block 2.

[0028] Self-lubricating layers 3-1b are provided at both side ends of each clamping plate 3-1.

[0029] A flared opening 2-1a in the shape of "V" is provided at the inlet end of the longitudinal through hole 2-1.

[0030] A set of rollers 3-1c are provided on the opposite surfaces of the two clamping plates 3-1.

[0031] A mounting seat 5 is installed on the lower side suspension block 2. Three support feet 6 arranged at equal angles are threadedly installed on the mounting seat 5. An adjusting rod 6-1 is threadedly connected to the bottom end of each support foot 6, and the bottom end of each adjusting rod 6-1 is a tip 6-1a.

[0032] Working principle of the utility model: When it is necessary to graft torreya grandis branch 8 onto torreya grandis sapling 9 (when grafting torreya grandis branch 8 onto torreya grandis sapling 9, it can provide better nutrition for torreya grandis, thus making the yield of torreya grandis higher), if the torreya grandis sapling 9 is relatively small, there is no need to use the support feet 6, and the support feet 6 and the mounting base 5 do not need to be installed (as Figure 7 shown), cut off the top of the torreya grandis sapling 9, then make an incision at the top of the torreya grandis sapling 9, and then, insert the hanging block 2 on the lower side into the flared opening 2-1a. Then, the torreya grandis sapling 9 squeezes the clamping plate 3-1 to open and presses the compression spring 3-4 to store energy. Continuously move the hanging block 2 on the lower side to make the torreya grandis sapling 9 located at the clamping opening 3-1a for clamping. Then, rotate the handle screws 3-5 on both sides to tighten the two clamping plates 3-1, so that the hanging block 2 on the lower side is firmly fixed at the torreya grandis sapling 9. Immediately afterwards, cut the end of the torreya grandis branch 8 into a wedge shape, and then squeeze it into the clamping opening 3-1a of the hanging block 2 on the upper side through the flared opening 2-1a. Then, the torreya grandis branch 8 is loosely clamped at the two clamping openings 3-1a of the hanging block 2 on the upper side. Then, continuously adjust the position of the torreya grandis branch 8 and make the end of the torreya grandis branch 8 insert into the incision of the torreya grandis sapling 9 and align with the epidermal nutrient layer position. After alignment, turn the two handle screws 3-5 on the hanging block 2 on the upper side, so that the two handle screws 3-5 on the hanging block 2 on the upper side tighten the two clamping plates 3-1 on the hanging block 2 on the upper side, so that the torreya grandis branch 8 is clamped in place without deviation, and the alignment of the nutrient layer position between the torreya grandis sapling 9 and the torreya grandis branch 8 is also not deviated. Subsequently, release the hand and use a transparent film to wrap the mating position between the torreya grandis sapling 9 and the torreya grandis branch 8, which not only fixes the position but also can lock the moisture and improve the survival rate. After the transparent film is wrapped well, loosen each handle screw 3-5, and then remove the device from the torreya grandis sapling 9 (as Figure 7 shown), and then the next plant can be grafted. The efficiency is high and the survival rate is high. When it is necessary to graft torreya grandis branch 8 onto a large torreya grandis sapling 9, the upper mounting base 5, the support feet 6, and the adjusting feet 6-1 can be used. The grafting process is the same as that of grafting torreya grandis branch 8 onto a small or large torreya grandis sapling (as Figure 8 shown); This device is made of a lightweight and high-strength polymer material, which is convenient to carry and use.

[0033] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
