本考案は、パケットの底壁の前縁部で形成される直線状
の掘削縁から前方へ突出した姿勢で前記パケット底壁に
ボルト止めされた掘削爪の固定構造に関する。[Detailed Description of the Invention] The present invention relates to a fixing structure for a digging claw that is bolted to the bottom wall of the packet in a posture that projects forward from a linear digging edge formed at the front edge of the bottom wall of the packet. .
上記のようなパケットへの掘削爪固定構造は、掘削爪に
かかる掘削反力により取付用ボルトに強大な力が加わり
、ボルトが弛んで爪のガタツきを生じたり、ボルトの変
形や破損を生じたりしやすく、従来では、爪後縁にのみ
に接当する固定部材にて掘削爪の掘削反力を受止めて、
上述の問題発生を防止しようとしていた。With the above-mentioned structure for fixing the excavation claw to the packet, the excavation reaction force applied to the excavation claw applies a huge force to the mounting bolt, which may loosen the bolt and cause the claw to rattle, or the bolt may become deformed or damaged. Conventionally, the digging reaction force of the digging claw is received by a fixed member that contacts only the trailing edge of the claw.
The attempt was made to prevent the above-mentioned problem from occurring.
しかし、実際には掘削反力の方向は常に爪長さ方向とは
限らず、爪−側部に右及び土塊等の硬質部分が存在する
場合等には、爪を回動させる方向への反力が作用し、そ
のために従来のもαは未だ十分に爪のガタッキ防止やボ
ルトの変形破損防止を威しえなかった。However, in reality, the direction of the excavation reaction force is not always in the claw length direction, and if there is a hard part such as a clod or a clod on the side of the claw, the reaction force will be in the direction of rotating the claw. Due to the force acting on the bolt, the conventional Mo-α has not yet been able to sufficiently prevent the pawl from rattling or the bolt from deforming and breaking.
本考案の目的は、かかる事情に鑑みて、爪固定部材の合
理的な配置構成により、あらゆる方向の掘削反力に対応
して、掘削爪のガタツキャボルトの変形破損を長期にわ
たって防止し得るようにする点にある。In view of the above circumstances, the purpose of the present invention is to prevent the deformation and damage of the rattling bolt of the excavating claw over a long period of time by responding to excavation reaction forces in all directions by rationally arranging the claw fixing member. At the point.
本考案の特徴構成は、冒記したパケットへの掘削爪固定

接当あるいは近接する固定部材を前記パケットの底壁に
固着し、前記固定部材を前記掘削爪の横巾内に配置した
点にある。The characteristic configuration of the present invention is that, in the above-mentioned structure for fixing the digging claw to the packet, fixing members in contact with or close to the rear end surface and both lateral end surfaces of the digging claw are fixed to the bottom wall of the packet, and the fixing member is fixed to the bottom wall of the packet. The point is that the member is arranged within the width of the digging claw.
本考案特徴構成による作用効果は、次の通りである。The effects of the characteristic configuration of the present invention are as follows.
つまり、掘削爪の後端面及び両横端面夫々に接当あるい
は近接する固定部材を前記パケットの底壁に固着し、前
記固定部材を前記掘削爪の横巾内に配置しである事を特
徴とする。In other words, a fixing member that contacts or is close to the rear end face and both lateral end faces of the digging claw is fixed to the bottom wall of the packet, and the fixing member is disposed within the width of the digging claw. do.
つまり、掘削爪に作用するあらゆる方向の掘削反力は、
その後端面及び両横側面夫々に接当あるいは近接する固
定部材にて受止められるから、爪のガタッキ、及びガタ
ッキによるボルト弛みに起因する爪脱落、あるいは、ボ
ルトの変形や破損を効果的に防止し得る。In other words, the digging reaction force in all directions acting on the digging claw is
Since it is received by a fixing member that contacts or is close to the rear end face and both side surfaces, it effectively prevents the jaw from rattling, the jaw from falling off due to loosening of the bolt due to rattling, and the deformation and damage of the bolt. obtain.
そのうえに、前記固定部材は、爪の横幅内に配置しであ
るから、掘削時に摩耗することがなく、長期にわたって
、良好な爪取付機能を維持させる事ができ、さらには、
単に固定部材の配置に改良を加えるだけであるから、実
施面においても有効である。Moreover, since the fixing member is arranged within the width of the claw, it will not wear out during excavation, and can maintain good claw attachment function over a long period of time.
Since it is merely an improvement in the arrangement of the fixing members, it is also effective in terms of implementation.
以下本考案の実施例を図面に基づいて詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.
