恐れがあつた。 As for conventional lightweight tilling claws, for example, as in Japanese Utility Model Publication No. 36-27508, reinforcing ribs are provided on the tilling claws to reduce the thickness of the tilling claws, resulting in a lightweight and reinforced shape. The tilling claws are used by being attached to the tilling holder of the rotatable tilling shaft, but in this case, the thinner the main part of the tilling claws, the smaller the driving resistance during driving, which is effective in terms of driving resistance and horsepower consumption. It will be very good. On the other hand, as described above, the reinforcing ribs provided on the tilling claws have a shape that protrudes laterally from the main body, which may cause driving resistance during driving.
そこで、この考案は、軽量、かつ強化耕うん爪
としての機能を備えると共に打ち込み時の打ち込

以下、図面に基づきこの考案の一実施例を詳細
に説明する。 Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

て一様な曲線の切込み刃２が設けられ、５は切込
み刃２の境界を示す。なお、切込み刃２は爪主体
を圧延することによつて容易に得られる。 1 and 2, the tilling claw of the present invention consists of a straight mounting base 1 with a rectangular cross section and an arcuate main body of the claw, and the mounting base 1 is slightly larger than the inner diameter of the tilling holder (not shown). A mounting bolt hole 1' is provided which is set to a small diameter and corresponds to the mounting hole of the tilling holder. The main body of the arc-shaped claw is formed into a substantially uniformly thin wall from the end of the mounting base 1 as shown by the dotted line in FIG. The tip of the main nail has a curved surface 3 that turns the soil over during driving. Furthermore, a cutting blade 2 having a uniform curve is provided inside the claw main body from the mounting base 1 to the tip of the claw main body, and 5 indicates the boundary of the cutting blade 2. Note that the cutting edge 2 can be easily obtained by rolling the main part of the claw.
一方、爪主体の幅方向中央部には前記取付基部
１の末端、すなわち爪主体との接点附近を起点と

パー状となつている。したがつて、前記弯曲面３
の側の反対側、すなわち第２図を裏側からみると
きは、前述のリブ６の部分が凹部となつており、
この状態は第３図に示されるとおりである。第３
図では、右側端部の上面、即ち、内側に切込刃２
が設けられているが、下面、即ち、外側に切込み
刃２を設けてもよい。 On the other hand, a reinforcing rib 6 is provided at the center in the width direction of the claw main body, starting from the end of the mounting base 1, that is, near the point of contact with the claw main body, and ending at a portion spanning the curved surface 3. . The rib 6 has a curvature that is approximately the same as the arc-shaped curvature of the main claw, and is narrow and high on the mounting base 1 side, becomes wider and lower as it approaches the curved surface 3, and has a tapered shape that disappears at the end. . Therefore, the curved surface 3
When viewed from the opposite side, that is, from the back side in FIG.
This state is as shown in FIG. Third
In the figure, there is a cutting blade 2 on the upper surface of the right end, that is, on the inside.
However, the cutting blade 2 may be provided on the lower surface, that is, on the outside.
このように構成された軽量強化耕うん爪にあつ
ては、取付基部１を図外の耕うんホルダに嵌挿
し、耕うんホルダの取付孔及び取付ボルト孔１′
を挿入し、そのねじ部にナツトを螺合することで
一般的な標準の耕うんホルダーに対して支障なく
取付けられる。 In the case of the lightweight reinforced tilling claw constructed in this way, the mounting base 1 is inserted into a tilling holder (not shown), and the mounting hole and the mounting bolt hole 1' of the tilling holder are inserted.
By inserting the holder and screwing the nut onto the threaded part, it can be installed on a standard tillage holder without any problems.
耕うんホルダに取付けられた耕うん爪は第２図

め、打ち込み時の打ち込み抵抗は最小に抑えられ
る。 The tilling claw attached to the tilling holder is driven into the field while rotating counterclockwise in FIG. It will work. At the same time, the reinforcing rib 6 also cuts into the cutting edge 2.
Similarly, since it acts on the field sequentially from the mounting base 1 side, the driving resistance during driving can be suppressed to a minimum.
一方、爪主体に巻き付く藁等はテーパー状のリ
ブ６によつて外側へ振り出されると共に取付基部
１と爪主体との境界附近に集中する力はリブ６に
よつてふんばるようになり剛性が確保される。 On the other hand, the straw, etc. wrapped around the main part of the claw is swung outward by the tapered rib 6, and the force concentrated near the boundary between the mounting base 1 and the main part of the claw is spread out by the rib 6, and the rigidity is increased. Secured.

み抵抗、消費馬力の面で大変好しいものとなる。
また、切込刃に続いてリブが一定の関係で作用す
るため振動も小さく抑えられる。 As explained above, the lightweight reinforced tilling claws of this invention can save material by being thinner and prevent straw from getting wrapped around them, and the ribs provide rigidity against stress concentration compared to conventional lightweight tillers. The same effect as reinforced tiller claws can be expected, but in addition, the reinforcing ribs act sequentially from the mounting base toward the tip when driving into the field, making it possible to minimize driving resistance. This is very favorable in terms of driving resistance and horsepower consumption.
Furthermore, since the ribs act in a fixed relationship following the cutting blade, vibrations are also kept to a minimum.
