EXCAVATING-CUM-GROUND-LEVELING TOOL FOR BUCKET OF SHOVEL MACHINE FOR CIVIL ENGINEERING WORK

PROBLEM TO BE SOLVED: To mold a ground leveling plate and a tooth holder by completely separating them from each other, enable mounting without selecting a pitch of a bucket tooth by fitting the ground leveling plate and the tooth holder into each other so that they can be slidably adjusted in use, facilitate the replacement of the tooth holder, and enhance ground leveling accuracy, in terms of a soil leveling tool for a bucket of a shovel machine. SOLUTION: In a structure, a guide member (2) is laterally molded in the ground leveling plate (1); run off (3) for insertion/extraction of a lock pin for attachment/detachment of a tooth member (T) is formed in an upper position along the guide member (2); a recessed groove guide (8) is molded at a lower position along the guide member (2) long from side to side; a lower protrusion piece (40) of the tooth holder (4) for fixedly attaching the tooth member (T) of the bucket (B) is fitted slidably along the guide (8); and the lock pin (7) is inserted, coupled and fixed into a hole (6), which is provided in the tooth holder (4), and a hole (h) of the tooth member (T) via the run off (3) of the plate (1).
