爪取付部構造に関する。[Detailed Description of the Invention] The present invention is an earthwork packet excavation claw in which a digging claw is attached to the opening edge of the packet body with bolts and nuts, and the nut is positioned in a recessed groove formed in the digging claw. Regarding the mounting structure.
この種のものでは、掘削に伴い、土砂や石が、ナツトよ
り突出したボルトの先端に衝突し、その先端のネジ部を
損傷し、ナツトを取外せず、掘削爪を取外せなくなる問
題があった。With this type of bolt, there is a problem that during excavation, dirt and stones collide with the tip of the bolt that protrudes from the nut, damaging the threaded part at the tip, making it impossible to remove the nut and the digging claw. Ta.
そこで、ボルトの先端をナツトから突出しないようにす
る事が考えられるが、ボルトに対する締付けが弱く掘削
爪の取付強度を低下する問題があった。Therefore, it is possible to prevent the tip of the bolt from protruding from the nut, but there is a problem in that the bolt is not tightly tightened and the mounting strength of the digging claw is reduced.
本考案は、上記の点に鑑み、掘削爪の取付強度を低下す
る事無く、ボルト先端の損傷に起因して掘削爪の取外し
が不能となるのを回避できるようにする事を目的とする
。In view of the above points, it is an object of the present invention to avoid the impossibility of removing the digging claw due to damage to the tip of the bolt, without reducing the mounting strength of the digging claw.
次に、本考案実施の態様を例示図に基いて詳述する。Next, embodiments of the present invention will be described in detail based on illustrative drawings.

しである。A curved packet bottom plate 1 is provided with side plates 2 facing each other.
.
Bolt 6... and Natsu 7...
For example, it is configured as an earthwork packet to be attached to the tip of an arm of a backhoe or the like to perform ground excavation work.

ように構成しである。The digging claw 5 is provided with a notch 9 on the side of the attachment base 8 to the packet main body 4 to fit the bottom plate 1, and
A recessed groove 11 is formed in the upper part to surround the bolt insertion holes 10, 10, and the tips of the nut 7 and bolt 6 are located in the recessed groove 11 when the excavating claw 5 is attached. It is configured as follows.
前記凹入溝１１の周壁１２に、前記ナツト７及びボルト
６の先端より上方側に位置する状態で嵌入溝１３を穿設

先端が外部に露出する事の無いように構威しである。A fitting groove 13 is formed in the peripheral wall 12 of the recessed groove 11 in a state located above the tips of the nuts 7 and bolts 6, and a protective plate 14 having elasticity is fitted into the fitting groove 13. The structure is such that the tips of the nuts 7 and bolts 6 are not exposed to the outside.

ように構成しである。The protective plate 14 is formed into an angular shape by bending one end thereof, and the bent portion 15 forms the plate 14.
It is configured so that it can be easily driven into the insertion groove 13 and easily pulled out, and is also configured so that the end portion of the recessed groove 11 can be covered as much as possible.
以上要するに、本考案は、冒記した土工用パケットの掘

前記掘削爪５に弾性的に嵌着しである事を特徴とする。In summary, the present invention provides the protection plate 14 for the tips of the nuts 7 and bolts 6 in the recessed groove 11 in the excavation pawl attachment structure of the earthworks packet described above.
It is characterized in that it is elastically fitted into the digging claw 5.
つまり、保護プレート１４により、ボルト６の先端を保

回避して強力に締付ける事ができるに至り、掘削爪５を
パケット本体４に、その取付強度を低下させる事無く、
かつ、取外しを容易に行える状態で取付ける事ができる
に至った。In other words, the protection plate 14 protects the tip of the bolt 6 and prevents dirt, stones, etc. from colliding with the tip of the bolt 6 during excavation and damaging the threaded portion on the tip side. Even if the tip protrudes, it can be tightened strongly without becoming unremovable, and the digging claw 5 can be attached to the packet body 4 without reducing its attachment strength.
Moreover, it has become possible to install the device in a state where it can be easily removed.
