以下、本発明を図１乃至図３に示された一実施の形態、図４に示された他の実施の形態、図５に示されたさらに別の実施の形態を参照しながら詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to one embodiment shown in FIGS. 1 to 3, another embodiment shown in FIG. 4, and still another embodiment shown in FIG. 5. To do.

先ず、図１乃至図３に示された一実施の形態を説明する。   First, an embodiment shown in FIGS. 1 to 3 will be described.

容器状に形成されたバケット本体５の開口先端部には、平板状のエッジプレート5eが設けられている。このエッジプレート5eには、図３に示されるようにアダプタ嵌着凹部12がコ字状に切欠形成されている。   A flat edge plate 5e is provided at the opening end of the bucket body 5 formed in a container shape. In this edge plate 5e, as shown in FIG. 3, an adapter fitting recess 12 is cut out in a U-shape.

図１に示されるように、このアダプタ嵌着凹部12にツースアダプタ13のアダプタ取付基部14が嵌着され溶接されている。このアダプタ取付基部14は、従来のツースアダプタ７のようなエッジプレート挿入溝7b（図８および図９参照）を設けることなく、図３に示されるように直方体形状に形成されている。   As shown in FIG. 1, the adapter mounting base 14 of the tooth adapter 13 is fitted and welded to the adapter fitting recess 12. The adapter mounting base portion 14 is formed in a rectangular parallelepiped shape as shown in FIG. 3 without providing an edge plate insertion groove 7b (see FIGS. 8 and 9) unlike the conventional tooth adapter 7.

したがって、アダプタ取付基部14の直方体形状は、図２に示されるように厚さａが、従来のエッジプレート挿入溝を省略した分だけ小さく抑えられる。   Therefore, the rectangular parallelepiped shape of the adapter mounting base portion 14 can be kept small by the thickness a as much as the conventional edge plate insertion groove is omitted as shown in FIG.

ツースアダプタ13は、このアダプタ取付基部14から突出されたノーズ部15を一体に有する。このノーズ部15の上面および下面は、アダプタ取付基部14から先端面にわたって楔形に傾斜した斜面を有し、左右の側面間には、ピン挿入穴16が貫通して形成されている。   The tooth adapter 13 integrally includes a nose portion 15 protruding from the adapter mounting base portion 14. The upper and lower surfaces of the nose portion 15 have slopes inclined in a wedge shape from the adapter mounting base portion 14 to the distal end surface, and pin insertion holes 16 are formed between the left and right side surfaces.

エッジプレート5eのアダプタ嵌着凹部12とツースアダプタ13のアダプタ取付基部14との接合面は、平面視でコ字状に形成され、図１および図２に示されるように、これらの接合面に沿ってなされる溶接により溶接継手部17が形成されている。この溶接継手部17は、エッジプレート5eの上面および下面の両面に対してそれぞれ設けられた隅肉溶接である。   The joint surface between the adapter fitting recess 12 of the edge plate 5e and the adapter mounting base portion 14 of the tooth adapter 13 is formed in a U shape in plan view, and as shown in FIG. 1 and FIG. A welded joint portion 17 is formed by welding performed along. The welded joint portion 17 is fillet weld provided on both the upper surface and the lower surface of the edge plate 5e.

このようにして溶接継手部17によりエッジプレート5eにアダプタ取付基部14を溶接されたツースアダプタ13のノーズ部15に、ソケット状のツースチップ18が嵌脱可能に嵌着されている。このツースチップ18には、ノーズ部15と嵌合する楔形の溝19が設けられ、ノーズ部15のピン挿入穴16と対応する側面にピン挿入穴20が形成されている。   In this manner, the socket-shaped tooth chip 18 is detachably fitted to the nose portion 15 of the tooth adapter 13 in which the adapter mounting base portion 14 is welded to the edge plate 5e by the welded joint portion 17. The tooth chip 18 is provided with a wedge-shaped groove 19 that fits into the nose portion 15, and a pin insertion hole 20 is formed on a side surface corresponding to the pin insertion hole 16 of the nose portion 15.

ノーズ部15のピン挿入穴16とツースチップ18のピン挿入穴20には、止着手段としてのピン21が着脱可能に挿入される。すなわち、ピン21の一側部には環状溝22が設けられ、一方、ツースアダプタ13のピン挿入穴16の一側部の拡大溝16aにはＣ形のリテーナ23が嵌着され、ピン挿入時にピン21の環状溝22とこのリテーナ23とが嵌合して、ピン21の抜止めとなるが、ピン21をリテーナ23から外してピン挿入穴16，20より抜取ることも可能であり、これにより、摩耗したツースチップ18をノーズ部15から取外して新品と交換することができる。   A pin 21 as a fastening means is detachably inserted into the pin insertion hole 16 of the nose portion 15 and the pin insertion hole 20 of the tooth chip 18. That is, an annular groove 22 is provided on one side of the pin 21, while a C-shaped retainer 23 is fitted in the enlarged groove 16 a on one side of the pin insertion hole 16 of the tooth adapter 13. The annular groove 22 of the pin 21 and the retainer 23 are fitted to prevent the pin 21 from being removed. However, the pin 21 can be removed from the retainer 23 and removed from the pin insertion holes 16 and 20. Thus, the worn tooth tip 18 can be removed from the nose portion 15 and replaced with a new one.

次に、この図１乃至図３に示された作用効果を説明すると、
エッジプレート5eに切欠形成したアダプタ嵌着凹部12に、ツースアダプタ13のアダプタ取付基部14を嵌着して、このアダプタ取付基部14とエッジプレート5eとの接合面を溶接継手部17により固定する。 Next, the operational effects shown in FIGS. 1 to 3 will be described.
The adapter mounting base portion 14 of the tooth adapter 13 is fitted into the adapter fitting recess 12 formed in the edge plate 5e in a notch, and the joint surface between the adapter mounting base portion 14 and the edge plate 5e is fixed by the welded joint portion 17.

ツースアダプタ13のノーズ部15にツースチップ18を嵌合して、これらのピン挿入穴16，20に一側よりピン21を挿入し、リテーナ23で係止する。ツースチップ18が摩耗、損壊したら、ピン21をリテーナ23から外してピン挿入穴16，20より抜取り、新品と交換する。   The tooth chip 18 is fitted into the nose portion 15 of the tooth adapter 13, the pin 21 is inserted into the pin insertion holes 16 and 20 from one side, and is locked by the retainer 23. When the tooth tip 18 is worn out or damaged, the pin 21 is removed from the retainer 23 and removed from the pin insertion holes 16 and 20 and replaced with a new one.

エッジプレート5eのアダプタ嵌着凹部12に、ツースアダプタ13のアダプタ取付基部14を嵌着して溶接したので、アダプタ取付基部14内に従来のようなエッジプレート挿入溝を設ける必要がなく、このエッジプレート挿入溝を省略した分だけアダプタ取付基部14の厚さａを最小限に抑えることができる。   Since the adapter mounting base 14 of the tooth adapter 13 is fitted and welded to the adapter mounting recess 12 of the edge plate 5e, there is no need to provide a conventional edge plate insertion groove in the adapter mounting base 14, and this edge The thickness a of the adapter mounting base 14 can be minimized by the amount that the plate insertion groove is omitted.

このため、掘削抵抗すなわちツース貫入抵抗を軽減でき、また、小形でシンプルな形状のツースアダプタ13を鋳造、鍛造などにより容易に製作でき、また、ツースアダプタ13の軽量化を図ることができ、また、バケット外面側への凸部を低く抑えることができるので、バケット外面を利用した均し作業の際に、バケット外面の凸部による筋状の掘起しを防止できるとともに、バケット内面側への凸部を低く抑えることができるので、バケット内土砂の排土を容易にできる。   For this reason, the drilling resistance, that is, the penetration resistance of the tooth can be reduced, the small and simple tooth adapter 13 can be easily manufactured by casting, forging, and the weight of the tooth adapter 13 can be reduced. Since the convex part on the bucket outer surface side can be kept low, the leveling work using the bucket outer surface can prevent streaking due to the convex part on the bucket outer surface and Since the convex portion can be kept low, the soil in the bucket can be easily discharged.

また、薄肉化にもかかわらず、エッジプレート挿入溝の省略によってアダプタ取付基部14で必要な肉厚を確保するとともに、従来と同様の長さを有する溶接継手部17により必要な溶接量を確保することで、アダプタ連結強度の低下を防止できる。   In addition, despite the thickness reduction, the necessary thickness is secured at the adapter mounting base 14 by omitting the edge plate insertion groove, and the required welding amount is secured by the welded joint portion 17 having the same length as the conventional one. Thereby, the fall of adapter connection intensity | strength can be prevented.

さらに、アダプタ嵌着凹部12およびアダプタ取付基部14の接合面をコ字状に形成することで、これらの加工成形を容易にできる。   Furthermore, by forming the joint surface of the adapter fitting recess 12 and the adapter mounting base 14 in a U-shape, it is possible to easily process and mold these.

次に、図４は、他の実施の形態を示し、ツースアダプタ13のアダプタ取付基部14におけるエッジプレート5eとの接合面、すなわち左右側面および背面に、エッジプレート5eのアダプタ嵌着凹部12と嵌合する凹溝14aが形成され、この凹溝14aがエッジプレート5eのアダプタ嵌着凹部12に嵌着された上で、接合面に沿ってなされる溶接により溶接継手部17が形成されている。   Next, FIG. 4 shows another embodiment, and the adapter fitting recess 12 of the edge plate 5e is fitted to the joint surface of the adapter mounting base 14 of the tooth adapter 13 with the edge plate 5e, that is, the left and right side surfaces and the back surface. A concave groove 14a to be joined is formed, and the concave groove 14a is fitted into the adapter fitting concave portion 12 of the edge plate 5e, and a welded joint portion 17 is formed by welding performed along the joining surface.

このように、エッジプレート5eのアダプタ嵌着凹部12とアダプタ取付基部14の凹溝14aとを嵌合させる構造により、この嵌合部分で荷重を分担できる分、溶接継手部17に作用するせん断力を軽減でき、連結強度を向上できる。   Thus, the structure that fits the adapter fitting recess 12 of the edge plate 5e and the concave groove 14a of the adapter mounting base 14 allows the load to be shared by this fitting part, and the shear force acting on the welded joint part 17 Can be reduced and the connection strength can be improved.

次に、図５は、さらに別の実施の形態、すなわちツースアダプタ13の変形例を示し、エッジプレート5eのアダプタ嵌着凹部12がＵ字状に切欠形成されるとともに、ツースアダプタ13のアダプタ取付基部14の外形もＵ字状に成形されている。すなわち、アダプタ嵌着凹部12およびアダプタ取付基部14の接合面が、平面視で角部を有さないＵ字状に形成されたものである。なお、上記実施の形態と同様の部分には、同一符号を付して、その説明を省略する。   Next, FIG. 5 shows still another embodiment, that is, a modified example of the tooth adapter 13. The adapter fitting recess 12 of the edge plate 5 e is notched in a U shape, and the adapter mounting of the tooth adapter 13 is performed. The outer shape of the base 14 is also formed in a U shape. That is, the joint surface between the adapter fitting recess 12 and the adapter mounting base 14 is formed in a U shape having no corners in plan view. In addition, the same code | symbol is attached | subjected to the part similar to the said embodiment, and the description is abbreviate | omitted.

このように、アダプタ嵌着凹部12およびアダプタ取付基部14の接合面をＵ字状に形成することで、この接合面に沿って同様にＵ字状に形成された溶接継手部（図示せず）は平面的に角部を持たない形状であるから、溶接継手部に作用する応力を分散させて、溶接継手部の破損につながる応力集中を低減できる。   In this way, the joint surface of the adapter fitting recess 12 and the adapter mounting base 14 is formed in a U shape, and a weld joint portion (not shown) similarly formed in a U shape along the joint surface. Since the shape does not have a corner portion in a plane, the stress acting on the welded joint portion can be reduced by dispersing the stress acting on the welded joint portion.
