Description

本発明は、耕耘機の耕耘軸に装着して、畑などの圃場を耕耘する際に使用する耕耘爪体に関するものである。 The present invention relates to a cultivating claw body that is attached to a cultivating shaft of a cultivator and used when cultivating a field such as a field.

従来から、耕耘作業に用いられる爪としては直線爪やなた爪などが知られており、耕耘作業にはこれらの爪が一般的に用いられている。直線爪は、耕耘する圃場の土壌が固い場合でも少ない馬力で圃場を耕耘することができ、耕した土は前方や上方に飛ばされる。一方、なた爪は耕した土を側方へ飛ばすことができるため土寄せなどの作業には適しているが、圃場の土壌が固い場合には土を耕すのに直線爪に比べて高い馬力を必要とし、耕耘機の高馬力化の一因となっている。 Conventionally, as a nail | claw used for a tilling operation | work, a straight nail | claw, a nail | claw, etc. are known, and these nail | claws are generally used for the tilling | working work. The straight claw can cultivate the field with a small horsepower even when the field to be cultivated is hard, and the cultivated soil is blown forward or upward. On the other hand, nail claws can fly plowed soil to the side, so they are suitable for work such as mulching. However, when the soil in the field is hard, the horsepower is higher than that of straight claws. It is necessary and contributes to the increase in the power of the tiller.

耕耘機の機体中央に前後方向に沿う取付軸を設け、この軸の左右両側に耕耘カバーを取り付けて、土壌が固い圃場において土寄せなどの作業を行う場合にはこの耕耘カバーを上方に回動して左右を開き、直線爪で耕して上方へ飛ばした土を耕耘カバーに当てることによって、耕耘機の側方へ土を寄せることが行なわれている。 At the center of the field of the tiller, a mounting shaft is provided along the front-rear direction. At the left and right sides of this shaft, a tilling cover is attached. The soil is moved to the side of the cultivator by opening the left and right sides, plowing it with straight claws and flying it upward.

しかし、この方法では側方へ土を飛ばすには耕耘カバーを大きく回動させて開かなければならないため土寄せ距離の調節が難しいうえに土が広範囲に飛散してしまい土寄せ効率が悪い。また、耕耘カバーの開きを小さくすると、上方に飛ばした土がカバーに当たってそのまま落下してしまい、機体に近い場所には土を寄せることができないなどの不都合があった。また、土壌が固い圃場において土寄せを行う場合に、直線爪で耕耘した後、なた爪で土寄せを行なうなど、余計な手間と労力がかかっていた。 However, in this method, in order to fly the soil to the side, the tillage cover has to be pivoted and opened. Therefore, it is difficult to adjust the earth moving distance, and the earth is scattered over a wide area, resulting in poor earth moving efficiency. Further, if the opening of the tillage cover is made small, the soil blown upward hits the cover and falls as it is, and there is a disadvantage that the soil cannot be brought close to the body. In addition, when carrying out mulching in a field where the soil is hard, extra labor and labor are required such as plowing with straight claws and then culling with tan nails.

解決しようとする問題点は、土壌の固い圃場における土寄せなどの作業に余計な手間と労力がかかっていた点である。 The problem to be solved is that extra work and labor are required for work such as mulching in a field with hard soil.

本発明は、耕耘軸に対し放射状に取り付ける取付け基部の回転方向前側の側辺を刃先部を回転方向前方に向け湾曲して形成し、この側辺に沿って溶接する耕耘爪の溶接基部を取付け基部に対しその板面が斜めに交差するようになし、そして溶接基部に一体的に連なる耕耘爪の刃先部を三日月状に刃先に近いほど幅を狭く且つ刃先を外向きに湾曲して形成したことを特徴とする。 In the present invention, the side of the mounting base that is mounted radially with respect to the tilling shaft is formed by curving the front side of the mounting base with the cutting edge facing forward in the direction of rotation, and the welding base of the tilling claw for welding along this side is mounted. The plate surface is obliquely crossed with respect to the base, and the cutting edge of the tilling nail integrally connected to the welding base is formed in a crescent shape so that the width is narrower and the cutting edge is curved outward as the cutting edge is closer. It is characterized by that.

本発明は、耕耘爪の刃先部を三日月状には先部に近いほど幅を狭く形成したことにより、この刃先で固い土壌を深くまで耕耘し、耕起した土を外向きに湾曲した刃先部によって耕耘機の機体側方に飛ばすことができるため、土壌の固い圃場においても少ない馬力で深くまで耕耘できると共に土寄せ等を行なうことができる。 In the present invention, the cutting edge portion of the tilling nail is formed so that the width becomes narrower as it approaches the tip in a crescent shape. Can fly to the side of the body of the cultivator, so that it can be cultivated deeply with a small amount of horsepower even in a soily field, and can perform soiling and the like.

以下、本発明に係る耕耘爪体の実施形態について図１乃至図５を参照して説明する。図１は本発明に係る耕耘爪体の溶接基部を板面側から見た図である。また、図２は耕耘爪体の溶接基部を側辺側から見た図で、図１の左側面図である。 Hereinafter, an embodiment of a tilling nail body according to the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a view of a welding base portion of a tilling claw body according to the present invention as viewed from the plate surface side. Moreover, FIG. 2 is the figure which looked at the welding base of the tilling nail | claw body from the side, and is a left view of FIG.

耕耘爪体１は、短冊形に形成された溶接基部３と、この溶接基部３の長さ方向に連続的に形成されると共にその両側辺が幅方向の一方に湾曲した刃先部４とを備え、刃先部４の端縁を溶接基部３の端縁と平行に形成してこの刃先部４の端縁に刃先６を設け、溶接基部３と刃先部４とからなる耕耘爪２を形成して、耕耘軸に装着する長板状の取付け基部５の側辺を耕耘爪２の板面に斜めに交差して取り付けて構成される。 The tilling claw body 1 includes a welding base portion 3 formed in a strip shape, and a cutting edge portion 4 which is continuously formed in the length direction of the welding base portion 3 and whose both sides are curved to one side in the width direction. The edge of the blade edge portion 4 is formed in parallel with the edge of the weld base portion 3, the blade edge 6 is provided on the edge of the blade edge portion 4, and the tilling claw 2 composed of the weld base portion 3 and the blade edge portion 4 is formed. The side of the long plate-shaped attachment base 5 to be mounted on the tilling shaft is attached to the plate surface of the tilling claw 2 so as to cross obliquely.

取付け基部５は、図示しない耕耘軸に設けられる爪ホルダに装着しボルトを挿通して固定するための取付け穴８を備えており、取付け基部５の板面が、耕耘軸に直交する面と平行に爪ホルダに取り付けられる。 The mounting base 5 is provided with a mounting hole 8 that is attached to a claw holder provided on a tillage shaft (not shown) and is fixed by inserting a bolt, and the plate surface of the mounting base 5 is parallel to a surface orthogonal to the tilling shaft. It is attached to the nail holder.

図３及び図４は耕耘爪体１の取付け基部５を側辺又は板面の方向から見た図であり、これは耕耘爪体１を耕耘軸に取り付けたとき、耕耘機の機体正面又は機体側面から耕耘爪体１を見た場合に相当する。つまり、図３においては左右方向が耕耘軸の向きであり、図４においては紙面に垂直な方向が耕耘軸の向きとなる。また、図５は図１のＡ−Ａ断面を示している。 3 and 4 are views of the attachment base 5 of the tilling claw body 1 as viewed from the side or the plate surface direction. This is the front or body of the tiller when the tilling claw body 1 is attached to the tilling shaft. This corresponds to the case where the tilling claw body 1 is viewed from the side. That is, in FIG. 3, the left-right direction is the orientation of the tilling axis, and in FIG. 4, the direction perpendicular to the paper is the orientation of the tilling axis. FIG. 5 shows an AA cross section of FIG.

図３及び図４に示したごとく、耕耘爪体１を爪ホルダに装着したときに、溶接基部３の板面は耕耘軸と直交する面に対して斜めに交差すると共に刃先部４の端縁に形成した刃先６の切っ先７が耕耘軸の回転方向最前端に位置するように取付け基部５の側辺に対して溶接基部３を斜めに取り付けて溶接などにより固着している。 As shown in FIGS. 3 and 4, when the tilling claw body 1 is mounted on the nail holder, the plate surface of the welding base 3 obliquely intersects the plane perpendicular to the tilling axis and the edge of the blade edge portion 4. The welding base 3 is obliquely attached to the side of the mounting base 5 so that the cutting edge 7 of the cutting edge 6 formed at the front end in the rotation direction of the tilling shaft is fixed by welding or the like.

図６は本発明に係る耕耘爪体を取り付けた耕耘機の側面図である。
耕耘機１０に取り付けられた耕耘爪体１は、その切っ先７が耕耘軸の回転方向（時計回り）最前端に位置し、また耕耘爪の溶接基部３は耕耘軸と直交する面に対して傾斜角を有するように配置されている。
また、耕耘機１０の正面視右側（紙面裏側）に取り付けられる耕耘爪は、図１乃至図５に示した耕耘爪体１と鏡像の関係にある。 FIG. 6 is a side view of a cultivator equipped with a cultivating claw according to the present invention.
The tilling claw body 1 attached to the tiller 10 has a cutting edge 7 positioned at the foremost end of the tilling shaft in the rotation direction (clockwise), and the welding base 3 of the tilling nail is inclined with respect to a plane orthogonal to the tilling axis. They are arranged to have corners.
Further, the tilling claw attached to the right side (back side of the paper) of the tiller 10 has a mirror image relationship with the tilling claw body 1 shown in FIGS. 1 to 5.

上記のごとく構成した耕耘爪体１は、耕耘爪の刃先部４を刃先６に近いほど三日月状に幅を狭く形成したことにより、この刃先６で固い土壌を深くまで耕耘すると共に、外向きに湾曲した刃先部４及び溶接基部３によって、耕した土を耕耘機１０の機体側方に飛ばすことができるため、土壌の固い圃場においても少ない馬力で所望の深さまで耕耘すると共に土寄せ等を行なうことができる。 The tilling nail body 1 configured as described above has a narrow crescent-shaped width as the cutting edge portion 4 of the tilling nail is closer to the cutting edge 6, so that hard soil can be deeply cultivated deeply with the cutting edge 6 and outward. Since the cultivated soil can be blown to the side of the body of the cultivator 10 by the curved cutting edge portion 4 and the welded base portion 3, tilling to a desired depth with a small horsepower even in a hard soil field can be performed. Can do.

また、上述の実施形態では溶接基部３及び刃先部４からなる耕耘爪２と取付け基部５とを別体に形成し、これらを溶接などして固着して耕耘爪体１を構成していたが、図７又は図８に示すごとく耕耘爪２から取付け基部５を連続的に一体形成して耕耘爪体１を構成してもよい。 In the above-described embodiment, the tilling claw 2 including the welding base portion 3 and the blade edge portion 4 and the attachment base portion 5 are formed separately, and these are fixed by welding or the like to constitute the tilling claw body 1. As shown in FIG. 7 or FIG. 8, the tilling claw body 1 may be configured by continuously forming the mounting base 5 integrally from the tilling claw 2.
