EXCAVATING TOOTH AND BODY FOR EXCAVATING TOOTH

摘要

An excavating tooth includes a body and an abrasion-resistant layer. The abrasion-resistant layer has hardness higher than the body. The body includes a tip end face, a first face, a second face, a pair of first slope faces, and a pair of second slope faces. The abrasion-resistant layer includes a first abrasion-resistant layer section and a second abrasion-resistant layer section. The first abrasion-resistant layer section is formed on the tip end face. The second abrasion-resistant layer section is formed respectively on the pair of first slope faces and the pair of second slope faces. Thereby, it is possible to obtain an excavating tooth and a body for the excavating tooth capable of keeping a penetration force of a blade edge high in penetrating into an excavation subject.

主权项

1. An excavating tooth comprising:
a body having one end and the other end; and an abrasion-resistant layer formed on said body and having hardness higher than said body, said body including
a tip end face positioned at said one end,a first face and a second face extending respectively from said tip end face up to said other end and facing each other,a pair of first slope faces extending respectively from said tip end face toward said other end and forming an obtuse angle on said tip end face with said first face, anda pair of second slope faces extending respectively from said tip end face toward said other end and forming an obtuse angle on said tip end face with said second face, said abrasion-resistant layer including
a first abrasion-resistant layer section formed on said tip end face, anda second abrasion-resistant layer section formed respectively on said pair of first slope faces and said pair of second slope faces.
