Title: Excavating rod in extensive excavator
Inventor: SUGA KOICHI
IPC: E02D5/46
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To solve a problem of a conventional extensive excavator, i.e., the problem of inefficient bothersome connection or separation of an inner pipe to or from an outer pipe, because, at every connection or separation of the inner pipe, a swivel is connected to the excavator to advance a piston rod of its pipe and a bit operating rod is squeezed to open an excavating bit.
