With the development of modern forestry and fruit industry, new varieties of excellent forestry and fruit industry are continuously selected and bred, and fruit growers directly graft the scions of the new varieties to compatible big trees (old trees) for updating. The grafting knife is one of the production tools playing a key role in the grafting process. In the grafting process, a corresponding grafting knife is selected according to the grafting method and requirements, and if the selection is improper, the grafting speed, the grafting quality and the later survival rate are greatly influenced. At present, grafting knives with different shapes are available in the market (see figure 1), the blade surfaces of all grafting knives are planes, partial grafting work is carried out, particularly, when a big tree is used for bark grafting, the diameter difference between a scion and a stock is small, the cutting surface of the scion cannot be completely adhered to the xylem of the stock, gaps are formed on two sides of the scion, and the grafting survival rate is influenced to a great extent.

The grafting knife brings great convenience in the low-yield garden grafting optimization changing work in the forest and fruit industry production. If the diameter difference between the scion and the rootstock is larger, the gap formed on the sticking surface is smaller, for example, the diameter is larger, and the periphery is closer to the plane; however, in the grafting and optimization process of old trees (or big trees) with small diameter difference between the scion and the rootstock, the scion cutting surface and the xylem surface of the grafting insertion part of the rootstock can not be completely stuck together, the phloem of the grafting insertion part of the scion is pushed outwards, gaps with different degrees are generated, and the grafting survival rate is negatively influenced to a certain degree.

To improve the above technical problem, a large tree bark grafting knife is provided in the following embodiments.

Referring to fig. 1, the present embodiment provides a large tree bark grafting knife 10, which includes a handle 100 and a knife 200.

The cutter 200 is connected with the cutter handle 100;

the cutter 200 has a length direction from the holder 100 to the tip, and a width direction from one side to the other side of the blade face of the cutter 200; the length direction and the width direction form an included angle;

lengthwise, the tool 200 includes at least one arcuate blade face 300; and the arc-shaped blade face 300 extends to both sides of the blade face in the width direction.

In the prior art, since the cut of the scion material forms a straight bevel, the bevel portion of the scion has a predetermined thickness; the cut of the stock is also a straight oblique opening, when the oblique sheet of the scion is inserted into the oblique opening of the stock, because the oblique sheet is too thick, the scion cutting surface and the surface of the xylem of the grafting insertion part of the stock cannot be completely adhered together, the phloem of the grafting insertion part of the scion is pushed outwards, gaps of different degrees are generated, and the grafting survival rate is negatively influenced to a certain degree.

The big tree bark grafting knife 10 of the present scheme comprises a handle 100 and a knife 200 which are connected with each other. The portion of the knife 200 in which the scion and rootstock can be cut includes at least one curved facet 300. The arc-shaped blade face 300 can further cut the oblique sheets of the scions to form concave arc faces, so that the thickness of the oblique sheets is reduced, the gaps at the sticking positions of the scions and the stocks are reduced to the maximum extent, the wood surfaces of the scion cutting faces and the stock grafting insertion parts can be tightly stuck, and the grafting survival rate is obviously improved.

It should be further noted that the arc-shaped blade surface 300 of the cutter 200 can extend to both sides of the cutter surface along the width direction, and compared with a mode that the arc-shaped blade surface 300 does not extend, such arc-shaped blade surface 300 can cut the scion with a larger area and a larger depth, so that the scion cutting surface can be further thinned, the close adhesion of the scion and the rootstock at the adhesion position is ensured, and the success rate of grafting is improved.

Optionally, at least two of the plurality of curved edge surfaces 300 have different curvatures, which is advantageous in that the large bark grafting knife 10 can cut scion surfaces with different curvatures as required. Compared with the arc-shaped blade surface 300 with only one curvature, when the scion surface with different curvatures is required to be cut, the scion needs to be repeatedly cut and corrected to obtain the preset arc-shaped concave surface. The arc-shaped blade surface 300 with various bending radians is convenient for a user to select a preset arc-shaped blade surface 300 for one-step forming to obtain a desired arc-shaped concave surface, so that the efficiency of cutting the scion surface into the arc-shaped concave surface is remarkably improved, and the quality of the obtained arc-shaped concave surface is better.

Alternatively, the curvature of the plurality of arcuate blade surfaces 300 may vary. The arc-shaped blade surfaces 300 which are different from each other can further improve the efficiency of the big tree bark grafting knife 10 for cutting the scion surface into the arc-shaped concave surfaces with different radians, and ensure the forming quality of the arc-shaped concave surfaces.

In addition, the cutting edge surface of the grafting knife 10 for bark grafting of big trees has cambered surface structures with different degrees, and can be used in bark grafting and other grafting processes. Furthermore, the blade face part is designed with cambered surface structures of different degrees, the concave cambered surfaces are carried out on the scion cutting faces of different diameters according to the diameter of the stock, the gap between the scion and the stock is reduced to the maximum extent, the survival rate is obviously improved, the secondary tool is simple and convenient to manufacture, and a planar tool face can be cut.

As can be seen, in the present embodiment of the invention, the plurality of arc-shaped blade faces 300 are all disposed on the side of the planar blade face 400 away from the handle 100. That is, the arc-shaped blade surface 300 is arranged in the direction of the plane blade surface 400 facing the tool nose, which is beneficial to the arrangement of the plane blade surface 400 and the arc-shaped blade surface 300, and the plane blade surface 400 has better structural strength, and the plane blade surface 400 is arranged at the position of the arc-shaped blade surface 300 close to the tool holder 100, so that the connection of the plane blade surface 400, the arc-shaped blade surface 300 and the tool holder 100 is more stable, and the structural strength and the structural toughness of the large bark grafting tool 10 can be enhanced.

On the other hand, because the sunken area of arc is less, the meticulous degree that needs during the cutting is higher, set up a plurality of arc facets 300 in plane facet 400 and keep away from handle of a knife 100 one side, the moment of force when the operator cuts is littleer, is convenient for control cutting dynamics to it is sunken to be the arc to be convenient for the scion face cuts more conveniently.

Further, in the present embodiment of the present invention, along the length direction, the plurality of arc-shaped blade faces 300 are connected end to end. The arc-shaped blade surfaces 300 connected end to end can improve the continuity and the integrity of the structure of the big tree bark grafting knife 10, and the arrangement mode can facilitate the switching and the selection among the arc-shaped blade surfaces 300; on the other hand, on the premise that the continuous end-to-end arc-shaped blade surfaces 300 can guarantee the using effect of the cutter 200, the length of the cutter 200 in the length direction is reduced, and the cost can be saved.

Immediately, in other embodiments of the present invention, the end-to-end connection of the arc-shaped blade faces 300 may not be end-to-end, for example, a planar blade face 400 is further provided between the arc-shaped blade faces 300, because each arc-shaped blade face 300 has one planar blade face 400, such an arrangement also enables the operator to switch between scion face cutting and rootstock cutting more efficiently. This is merely an example and is not intended to be limiting as long as the curved edge surface 300 is capable of cutting the graft surface to form a curved depression.

Further, in the present embodiment of the present invention, the cutting tool 200 includes a plurality of arc-shaped blade faces 300; the curvature of the plurality of arc-shaped blade faces 300 decreases in the lengthwise direction. The plurality of arc-shaped blade surfaces 300 with sequentially reduced curvature can concentrate the stress of the large-tree bark grafting knife 10 on the plane blade surface 400; the radian change of the arc-shaped blade surface 300 is in a slow reduction trend, and the structural damage of the big tree caused by stress change during the processing and the manufacturing of the big tree bark grafting knife 10 can be avoided; thus, the whole grafting knife 10 for bark grafting of big trees has better structural strength and better operation mode; on the other hand, the curved radian of a plurality of arc-shaped blade surfaces 300 is reduced in sequence, so that an operator can adjust and select a smaller radian along the length direction naturally, the use is simpler and more convenient, and the fool-proof and cutting-error-proof effects are achieved.

In the present embodiment of the present invention, along the length direction, the width of the planar blade surface 400 is the same as that of the arc-shaped blade surface 300 in the width direction. Therefore, the stress structure of each part of the cutter 200 of the grafting knife 10 for bark grafting of big trees is more stable and reliable, and the situation that the cutter point jumps to hurt people when the cutter 200 is too thin in the using process is avoided.

In the present embodiment of the present invention, along the length direction, the thickness of the planar blade face 400 is the same as that of the arc-shaped blade face 300. It can be understood that the cutter 200 having the same thickness can ensure the stability during cutting, and ensure the superior cutting quality and effect of the large-tree bark grafting knife 10.
