    • PROBLEM TO BE SOLVED: To provide an excavating tool that enables suitable excavation.
      SOLUTION: During excavation work in the ground G in which an excavating tool 100 is lowered, the front end face 11a and the collar 11b of a fitting part 11 are brought into a close contact with the lower bottom face 21a and the annular face 21b of a to-be-fitted part 21, respectively, to make it difficult for earth and sand to enter between a tool body 10 and an excavating unit 20. When a lifting work of lifting up the excavation tool 100 is started, a prescribed fluid is discharged from the inside of the excavating tool 100 to the outside thereof through a gap formed between the tool body 10 and the excavating unit 20. This prevents earth and sand from entering between the tool body 10 and the excavating unit 20 to keep the tool body 10 and the excavating unit 20 from being engaged with each other via earth and sand, allowing the excavating unit 20 to be removed easily from the tool body 10.

    • 要解决的问题:提供能够进行适当挖掘的挖掘工具。 解决方案:在挖掘工具100下降的地面G中的挖掘作业中,装配部11的前端面11a和轴环11b与下底面21a和环状部分 分配被安装部21的表面21b,使得砂土难以进入工具主体10和挖掘单元20之间。当开始提升挖掘工具100的提升作业时, 预定流体通过工具主体10和挖掘单元20之间形成的间隙从挖掘工具100的内部排出到外部。这样可防止砂土进入工具主体10和挖掘单元20之间,以保持 工具主体10和挖掘单元20通过砂土彼此接合,允许挖掘单元20从工具体10容易地取出。版权所有(C)2010,JPO&INPIT
