TOOTH STRUCTURE FOR BUCKET, AND BUCKET

KIYONO KAZUYA / SAKATA SEISAKU

PROBLEM TO BE SOLVED: To prevent a dropout of a left edge tooth member from an adapter by having an upper dropout prevention protrusion of the left edge tooth member come into contact with a top side of a holding protrusion of an intermediate tooth member adjacent on a right side of the left edge tooth member, and having the top side of the holding protrusion come into contact with the upper drop out prevention protrusion.SOLUTION: A tooth structure for a bucket comprises a left edge tooth member L at a left edge position, at least one intermediate tooth member C at an intermediate position, and a right edge tooth member R at a right edge position, laid out sequentially in a right-left direction opposite an edge side of a bucket 1. The left edge tooth member has an upper dropout prevention protrusion 7 formed to come into contact with a top side SU of a holding protrusion S of the intermediate tooth member adjacent on the right side of the left tooth member.SELECTED DRAWING: Figure 1

【課題】左端ツース部材がアダプタから抜け落ちようとしても、左端ツース部材の上側抜止凸部が左端ツース部材の右側に隣り合う中間ツース部材の挟持凸部の上辺部に当接し、挟持凸部の上辺部と上側抜止凸部との当接により左端ツース部材の抜け落ちを防止することができる。【解決手段】バケット１の先端辺部に対向して左右方向に順次配置される左端位置の左端ツース部材Ｌ、少なくとも１個の中間位置の中間ツース部材Ｃ及び右端位置の右端ツース部材Ｒからなり、左端ツース部材に右側に隣り合う中間ツース部材の挟持凸部Ｓの上辺部ＳＵに当接可能な上側抜止凸部７が形成されている。【選択図】図１
