摘要： PROBLEM TO BE SOLVED: To provide an assembly for securing a wear member to an excavator, in particular, for mounting an adaptor to a dredge cutter head. SOLUTION: The assembly for mounting an excavating tooth particularly suited for a dredge cutter head includes a base, an adapter, and a lock. The base includes a convex, curved bearing surface that abuts on a concaved and curved bearing surface on the adapter. The curved bearing surfaces can maintain substantially full contact with each other at transverse loading. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To protect an adaptor and a lock pin from abrasion. SOLUTION: An excavating tooth is assembled by fitting a point A' on an adaptor nose B" and by inserting a lock pin C" between them. In this state, the opposite ends of the lock pin engage respectively with an upper projecting part 29 and a lower projecting part 28 of an ear part 25 provided on one side wall of the point A', while the center of the lock pin engages with the front wall of a groove formed in the adaptor nose B". The ear part 25 extending to the rear of the point A' so acts as to protect an adaptor and the lock pin C".

摘要： PURPOSE: To prevent swiveling by extending a bottom wall to the front edge having a V shape and equipped with a plurality of excavation teeth, and arranging the teeth, projected sequentially forward toward the side wall from the longitudinal center line of the bucket. CONSTITUTION: The bottom wall 26 of a dragline bucket 12 is extended to the front edge 17 having a V shape and equipped with a plurality of excavation teeth 18. Subsequently, the teeth 18 are arranged in a V shape of an opposite direction in relation to the direction of movement of the bucket 12 during excavation, and the teeth 18 are arranged at the angle of about 75 deg. to about 80 deg.. Subsequently, the bucket 12 and a power device are connected by the dragline 15, a hoisting rope 14, and a dump rope 16. By applying a rope traction force to the dragline 15 arranged along the central line of the bucket 12, the teeth 18 on one side are engaged with an excavated material. The excavated material is crushed and collected in the front edge 17, and the bucket 12 is held stably to prevent punching and rotation. In addition, the filled bucket 12 is pulled up and the excavated material is discharged.

摘要： PURPOSE: To reduce wear and fatigue of a nose, to reduce loosening of a point fitting and to lengthen the life of the nose by providing a long supporting surface and a pair of lugs with space in a vertical direction on the point. CONSTITUTION: At a front tip part of a comparatively thin and long integral main body, a ground engaging edge part is provided and an adapter nose receiving socket formed by a top, a bottom part and a pair of side walls is provided. Next, at least one of the side walls is extended backward beyond the top and a bottom wall, and upper and lower ear projecting parts which are aligned so as to receive a lock pin C" and are away in a vertical direction are provided near top parts and bottom parts of the side walls. As a result, supporting pressure of a point in a nose B" is reduced, and wear and fatigue of the nose B" can be reduced.
