Description

本考案は、接木ナイフに関するものである。 The present invention relates to a graft knife.

従来、接木に使用されているナイフは図１に示すごとくの片刃の小刀で刃先が直線状のものであるから、接木の作業に於いて、台木や穂木を切削すると、その切削面は平らな面となる。 Conventionally, the knife used for grafting is a single-edged knife as shown in FIG. 1, and the cutting edge is linear, so when cutting rootstock and hogi in grafting work, the cutting surface is It becomes a flat surface.

従来より使用されている接木ナイフは、片刃の小刀で直線的な刃先を有するものであるから、台木や穂木を切削するとそれらの切削面は平らなものとなる。接木は、台木と穂木の切削面を向い合わせ両者の形成層同士をぴったりと重ね合わせ、その外周に接木テープを巻いてしめつけ両者の接触面に一定以上の圧力を加えておく作業であるが、この時に加えられる圧力は、台木と穂木の接触する全面に等しくかけられている訳ではない。他の部位よりも固い上に接触面積が一番広いことから、加えられる圧力の多くは、台木と穂木の木質部同士の接触する部位にかけられてしまう現実がある。しかし接木に於いて台木と穂木の切削面の中で、どの部位よりも優先してどの部位よりも強い圧力を加えたいのは、台木と穂木の形成層同士の接触部位の方である。この不合理は、従来の接木ナイフの刃先が直線状であることによって台木や穂木の切削面が平面に切削されるがゆえに生ずる課題である。 Since the grafting knife conventionally used is a single-edged knife and has a straight cutting edge, when cutting rootstock or hogi, their cutting surfaces become flat. Grafting is an operation in which the cutting surfaces of rootstock and hogi face each other, the formation layers of both are closely overlapped, and the grafting tape is wrapped around the outer periphery and squeezed to apply a certain level of pressure to the contact surfaces of both. However, the pressure applied at this time is not equally applied to the entire surface where the rootstock and hogi come into contact. Since it is harder than the other parts and has the largest contact area, there is a reality that much of the applied pressure is applied to the parts where the wood parts of the rootstock and hogi are in contact with each other. However, in the cutting of rootstock and hogi in grafting, we want to apply pressure stronger than any part in preference to any part. It is. This unreasonable problem is caused by the fact that the cutting surface of a conventional graft knife is straight and the cutting surfaces of rootstock and hogi are cut into a flat surface.

そこで、本考案は図２に示す如く、刃の切削方向に対して上方または下方に凹状に湾曲する刃を有する接木ナイフを用いて、台木や穂木の切削面が平面よりもゆるく凹んで切削することができる様にした。このようにすると、台木と穂木の切削面を向かい合わせて重ね圧力を加えても両者の木質部同士は接触せず、かけられる圧力のすべては台木と穂木の樹皮同士や形成層同士の接触する部位の方にかけられるようになる。 Therefore, as shown in FIG. 2, the present invention uses a grafting knife having a blade that curves concavely upward or downward with respect to the cutting direction of the blade, so that the cutting surface of rootstock and hogi is recessed more gently than the plane. I was able to cut. In this way, even if pressure is applied with the cutting surfaces of the rootstock and hogi facing each other, the wood parts of both do not contact each other, and all the applied pressure is between the bark of the rootstock and the hogi and between the formation layers It comes to be able to be applied toward the part where it touches.

本考案の、刃の切削方向に対して、上方又は下方に凹状に湾曲している刃を有する接木ナイフで、台木や穂木を切削すると、その切削面は平面よりもゆるく凹んで切削されるため、台木と穂木の切削面の樹皮同士、形成層同士を向い合わせて重ね、その外側に接木テープを巻いて締めつけ前記接触面に圧力を加えるとその圧力は、従来のように台木と穂木の木質部同士が接触することがなく、接木に於いて、切削面の中でどの部位よりも優先して圧力をつよくかけたい台木と穂木の形成層同士の接触部位に十分な圧力を加えることができるようになり、台木と穂木の切削面の両者の接触部位の空気をつよくしめだして密着させ、乾燥を防止して台木の形成層から穂木の形成層への水分や養分の移動や補給を容易にして接木の成功率を向上させることができる。また、前記により台木と穂木の木質部同士の接触がなくなった事により、接木テープを巻いて締めつける力は従来程に強くなくとも良くなり、接木の作業を楽にし作業効率を向上させる事ができる。 When cutting rootstock or hogi using a grafting knife having a blade that is concavely curved upward or downward with respect to the cutting direction of the blade of the present invention, the cutting surface is cut to be recessed more gently than the plane. Therefore, when the bark of the cutting surfaces of the rootstock and hogi and the formation layers are facing each other and overlapped, and the grafting tape is wrapped around the outer side and tightened, pressure is applied to the contact surface as in the conventional case. There is no contact between the wood parts of the wood and the hogi, and in the grafting, it is sufficient for the contact area between the formation layers of the rootstock and the hogi where you want to apply pressure preferentially over any part in the cutting surface. Pressure can be applied, and the air at the contact area of both the rootstock and the cutting surface of the rootstock is tightly adhered and closely adhered to prevent drying, so that Improve the success rate of grafting by making it easier to move and replenish moisture and nutrients It is possible. In addition, since the contact between the wood parts of the rootstock and the hogi is eliminated as described above, the force of winding and fastening the grafting tape does not have to be as strong as before, and the work of grafting can be facilitated and work efficiency can be improved. it can.

従来の接木ナイフ１は図１の如く直線的な刃先１１を有しているため、台木２や穂木３を切削すると、その切削面は平面になる。図２の如く従来の接木ナイフ１によって切削した台木２と穂木３の切削面を向かい合わせて重ね合わせると、台木２と穂木３の木質部２３と３３同士が接触して前記切削面の樹皮２１と３１同士、同じく形成層２２と３２同士の接触部位にかけたい圧力を妨害したり横取りしたりしている現実があるが接木の作業において最も優先して強い圧力を加えたいのは台木２と穂木３の形成層２２と３２同士の接触部位である。そこで本考案の接木ナイフ４は図４の如く、刃の切削方向に対して上方又は下方に凹状にゆるく湾曲した刃体４２を有する接木ナイフを設け台木２や穂木３を切削するとその切削面は平面よりもゆるく凹んで切削される。よって、図３の如く、台木２と穂木３の切削面を向かい合わせ、樹皮２１と３１、形成層２２と３２を重ね合わせその外側に接木テープを巻いてしめつけ前記の接触面に圧力を加えると、従来のように台木２と穂木３の木質部２３と３３同士が凹んでいて接触しないため、接木テープを巻いてしめつける圧力のすべては、台木２と穂木３の樹皮２１と３１、形成層２２と３２の接触部位にかけることができるようになった。かけられるその圧力はまずは外側の台木２と穂木３の樹皮２１と３１の接触面にかけられるがこの部位はやわらかい為、すぐに押しつぶされて平らになり次には台木２と穂木３の形成層２２と３２をつよく密着させ両者の間の空気をしめ出して乾燥を防止すると共に台木２の形成層２２から穂木３の形成層３２へ水分や養分を受け渡し、補給するのに十分な圧力を得て、接木の成功率を向上させることができる。従来のように、台木２と穂木３の切削面の木質部２３と３３同士の接触がなくなった事により接木テープを従来ほどに強く巻いて締めつけなくても十分な圧力が得られ、接木の作業が楽になり作業の能率も向上する。なお、本考案における接木ナイフの刃先は片刃、両刃の区別は特定しない。 Since the conventional graft knife 1 has a straight cutting edge 11 as shown in FIG. 1, when the rootstock 2 and the hogi 3 are cut, the cutting surface becomes flat. As shown in FIG. 2, when the cutting surfaces of the rootstock 2 and the hogi 3 cut by the conventional grafting knife 1 face each other and overlap, the wood parts 23 and 33 of the rootstock 2 and the hogi 3 come into contact with each other, and the cutting surface The bark 21 and 31 and the formation layers 22 and 32 are in contact with each other, and there is a reality that the pressure to be applied is intercepted or intercepted. This is a contact portion between the formation layers 22 and 32 of the tree 2 and the hogi 3. Therefore, as shown in FIG. 4, the grafting knife 4 of the present invention is provided with a grafting knife having a blade body 42 that is gently curved concavely upward or downward with respect to the cutting direction of the blade, and cutting the rootstock 2 and the hogi 3 is cut. The surface is cut with a recess that is looser than the plane. Therefore, as shown in FIG. 3, the cutting surfaces of the rootstock 2 and the hogi 3 face each other, and the barks 21 and 31 and the formation layers 22 and 32 are overlapped with each other and wrapped with a graft tape to apply pressure to the contact surface. In addition, since the wood portions 23 and 33 of the rootstock 2 and the hogi 3 are recessed and do not come into contact with each other as in the past, all the pressure to wrap the grafting tape and the bark 21 of the rootstock 2 and the hogi 3 31, it can be applied to the contact portion between the formation layers 22 and 32. The pressure to be applied is first applied to the contact surface of the bark 21 and 31 of the outer rootstock 2 and hogi 3, but this part is soft, so it is quickly crushed and flattened, and then the rootstock 2 and hogi 3 In order to replenish and replenish moisture and nutrients from the formation layer 22 of the rootstock 2 to the formation layer 32 of the hogi 3 With sufficient pressure, the success rate of grafting can be improved. As in the prior art, the contact between the wood portions 23 and 33 of the cutting surfaces of the rootstock 2 and the hogi 3 is eliminated, so that sufficient pressure can be obtained without winding and tightening the grafting tape as strongly as before. The work becomes easier and the work efficiency is improved. Note that the cutting edge of the grafting knife in the present invention does not specify the distinction between a single blade and a double blade.

実施例１同様、台木２や穂木３の切削面が平面よりもゆるく凹んで切削することができる接木ナイフを得る今一つの方法で、切削方向に対して、上方又は下方にゆるく湾曲した装着部６１を有するホルダー６を開いて、前記装着部６１にカミソリ刃の如く平板状の薄い刃体５を装着して挟持し、図７の如く、柄６２、６２を閉じ、バンド６３をはめて湾曲させた刃体５、刃先５１を有する接木ナイフを得る。この方式は摩耗した刃がすぐに取り替えられるので常に良好な切れ味を提供することができる。 As in Example 1, this is another method for obtaining a grafting knife that can be cut with the cutting surfaces of the rootstock 2 and the hogi 3 being looser than the plane, and mounting that is gently curved upward or downward with respect to the cutting direction. The holder 6 having the portion 61 is opened, a flat thin blade body 5 such as a razor blade is attached to the mounting portion 61, and the handle 62 and 62 are closed and the band 63 is fitted as shown in FIG. A grafting knife having a curved blade body 5 and a cutting edge 51 is obtained. This method can always provide a good sharpness because the worn blade is replaced quickly.
