Abstract:
1. An excavating bucket of a construction machine, comprising: a bottom plate whose ends in the width direction curve in a C shape; a pair of left and right side plates that along with the bottom plate form a box structure having a bottom part and an opening, the left and right side plates being attached to the ends of the bottom plate and forming a first angle with respect to a center line of the width direction of the bottom plate; a cutting edge attached to a distal end portion on an excavation side of the bottom plate, the cutting edge having a distal end part forming a widthwise center portion of the cutting edge, a pair of protruding parts disposed adjacent to the two widthwise opposite ends of the distal end part and protruding farther away from the bottom plate than the distal end part, and a pair of inclined parts disposed adjacent to the widthwise outside ends of the protruding parts such that each of the protruding parts is disposed between the distal end part and one of the inclined parts, each of the inclined parts being inclined at the first angle with respect to the distal end part such that a widthwise outer end of the inclined part is closer to the bottom plate than a widthwise inner end of the inclined part; a plurality of adapters fixed on the distal end side of the cutting edge, the adapters being configured to have tooth members attached to distal ends thereof to be used for excavation; and a pair of left and right corner adapters fixed with respect to the pair of inclined parts of the cutting edge, the corner adapters being configured to have tooth members attached to distal ends thereof to be used for excavation, the left and right corner adapters being arranged and configured such that distal end positions of the left and right corner adapters are disposed on a same line as distal end positions of the plurality of adapters.
