LINKAGE STRUCTURE FOR BUCKET AND ARM OF HYDRAULIC EXCAVATOR

摘要

PURPOSE: the excavator between connection bucket and arm is provided to cutting and flows into foreign matter by assembling in separated space and improving sealing power sealing element, because sealing is pressurized through elastomeric spring. ;CONSTITUTION: the method for the excavator between connection bucket and arm includes the following steps. A kind of bucket is rotatably connected to the excavator that front end passes through connecting pin and arm (110). It is separation that sealing element (160) insertion, which forms between space and connects medium, and flows into foreign matter.
