RIPPER POINT ATTACHMENT STRUCTURE AND RIPPER POINT

摘要

In a ripper point attachment structure (6), a pin member (13) is inserted into a first pin hole (23) formed in a ripper shank (11) and a second pin hole (42) formed in a ripper point (12). A lock member (14) is engaged with the pin member (13) and retains the pin member (13). The ripper point (12) has an opening (40h), an internal space (S), and a guide groove (41). The opening (40h) is formed at a rear end (40i). The internal space (S) is formed from the opening (40h) toward an end surface (40g). The guide groove (41) is formed in a predetermined area from the rear end (40i) toward the end surface (40g) in a part of an inner surface (40s) forming the internal space (S). The second pin hole (42) in the ripper point (12) is disposed on a bottom surface (41a) of the guide groove (41). The lock member (14) is disposed in a space forming the guide groove (41).
