    • PROBLEM TO BE SOLVED: To provide a bucket capable of suppressing the fall and damage of a segment edge and a working machine.
      SOLUTION: This bucket mounted on the working machine for transporting excavated sediment comprises a cutting edge 42 forming the end edge of the bucket. The cutting edge 42 comprises a plurality of teeth 43 installed at predetermined intervals and segment edges 44, 45, 46 disposed between the teeth 43 and installed so that the end portions project from the end of the cutting edge 42. The segment edges 44, 45, 46 comprise a plurality of weld parts arranged along the end edge of the cutting edge 42 and discontinuous parts formed between the plurality of weld parts, following up the deflection of the cutting edge, and discontinuous with respect to strength. Consequently, since the occurrence of a stress in the adhered portion is reduced, the damage and fall of the segment edges 44, 45, 46 at the adhered portion can be suppressed.

    • 要解决的问题:提供一种能够抑制段边缘和作业机械的跌倒和损坏的铲斗。

      解决方案:安装在作业机上用于运输挖掘的沉积物的该铲斗包括形成铲斗的端边缘的切削刃42。 切削刃42包括以预定间隔安装的多个齿43和设置在齿43之间的分段边缘44,45,46,并安装成使得端部从切削刃42的端部突出。段边缘44,45 46包括沿着切削刃42的端缘布置的多个焊接部件和形成在多个焊接部分之间的不连续部分,跟随切削刃的偏转,并且相对于强度是不连续的。 因此,由于粘附部分发生应力减小,所以能够抑制在粘合部分处的边缘44,45,46的损伤和下降。 版权所有(C)2007,JPO&INPIT
