Abstract
Description
例えば、油圧ショベルでは、作業機として、アームの先端に掘削バケットが装着される。掘削バケットの掘削側の先端部分に、先端部分から突出するように設けられた複数のアダプタが設けられている。そのアダプタの先端に交換可能な複数のツース(掘削具)がそれぞれ取り付けられる。そして、油圧ショベルを用いて掘削する際には、このバケットの掘削側の先端に設けられたツースが切刃として機能することで、掘削対象へ貫入されて掘削力を高めることができる。
すなわち、上記特許文献1に開示された建設機械の掘削バケットでは、バケットを構成する底板と左右の側板とが互い交錯する三辺に対してアダプタを溶接しているため、バケット構造としては強固になるものの、摩耗したアダプタを交換する作業が困難となる。
本発明の課題は、左右のコーナーアダプタの先端位置を他のアダプタの先端位置と同じライン上に揃えつつ、摩耗したアダプタの交換作業を容易に実施することが可能な建設機械の掘削バケットを提供することにある。
第1の発明に係る建設機械の掘削バケットは、底板と、左右一対の側板と、カッティングエッジと、複数のアダプタと、左右一対のコーナーアダプタと、接合部と、を備えている。底板は、C字状に湾曲する。左右一対の側板は、底板とともに開口部と底部を有するボックス構造を形成し、底板の幅方向の中心線に対して第1角度で開口部に向かって拡開するように取り付けられている。カッティングエッジは、底板の掘削側先端部分に取り付けられており、左右両端に第1角度で底部に向かって傾斜した傾斜部を有する。複数のアダプタは、カッティングエッジの先端側に固定され、先端に掘削用のツース部材が取り付けられる。左右一対のコーナーアダプタは、カッティングエッジの先端側における左右両端に設けられた傾斜部に対して固定され、先端に掘削用のツース部材が取り付けられるとともに、複数のアダプタの先端位置と同一ライン上に先端位置が配置されており、側板が間に挿入される凹部を有する。接合部は、コーナーアダプタをカッティングエッジに対してのみ連続溶接によって接合する。
これにより、コーナーアダプタの溶接箇所の数が少ないため、アダプタが摩耗した際の交換作業をより容易に実施することができる。
本発明に係る建設機械の掘削バケットによれば、左右のコーナーアダプタの先端位置を他のアダプタの先端位置と同じライン上に揃えつつ、摩耗したアダプタの交換作業を容易に実施することができる。
なお、以下の説明で登場する「左右方向」とは、掘削バケット10の底板11の湾曲していない辺の方向、すなわちアダプタが装着される辺の方向を指す。左右方向は、掘削バケット10および底板11の幅方向である。
本実施形態の掘削バケット10は、油圧ショベル等の建設機械のアーム先端に装着され油圧シリンダによって駆動される掘削用の作業機であって、図1に示すように、底板11、左右一対の側板12a,12b、装着部13、カッティングエッジ14、センターアダプタ15、コーナーアダプタ16,17、およびシュラウド18を備えている。

本実施形態の掘削バケット10では、図6に示すように、コーナーアダプタ16,17がカッティングエッジ14の上面、下面に対して溶接接合される際に、それぞれ接合部22a,22bを介して溶接接合される。
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。
上記実施形態では、コーナーアダプタ16,17が、それぞれカッティングエッジ14の上面側(接合部22a)と下面側(接合部22b)の2箇所において溶接接合されている例を挙げて説明した。しかし、本発明はこれに限定されるものではない。
上記実施形態では、センターアダプタ15を3つ有する掘削バケット10を例として挙げて説明した。しかし、本発明はこれに限定されるものではない。
例えば、センターアダプタ15を2つ、あるいは4つ以上有する掘削バケットに対して、本発明を適用することも当然に可能である。
上記実施形態では、油圧ショベルのアーム先端に装着される掘削バケットを例として挙げて説明した。しかし、本発明はこれに限定されるものではない。
例えば、他の建設機械に装着される掘削バケットに対しても、本発明の適用は可能である。
