Title (EN) BLADES FOR DIGGING ASSEMBLIES, RELATED APPARATUSES AND METHODS FOR USE THEREOF
(FR) LAME POUR ENSEMBLE D'EXCAVATION ET APPAREILS CORRESPONDANTS
Abstract: front page image
(EN) A blade (12) for a digging assembly comprises a base portion (24) and a terminal portion (26) remote from the base portion (24). The base portion (24) is wider than the terminal portion (26), and the blade tapers in width between the base and terminal portions (24, 26). First, second and third sharpened edges (28, 30, 32) are provided on the blade (12), each having flanks (34) that subtend an angle of at least 90°. Each of the flanks (34) are skewed in relation to the respective flanks (34) of the other edges. The orientation of the flanks (34) of the sharpened edges (28, 30, 32) enables the blade (12) to exhibit a lifting effect when it is rotated through material on an axis in a digging assembly.
(FR) L'invention concerne une lame (12) pour ensemble d'excavation se composant d'une partie de base (24) et d'une partie d'extrémité (26) éloignée de la partie de base (24). La partie de base (24) est plus large que la partie d'extrémité (26), et la lame s'amincit entre la partie de base et la partie d'extrémité (24, 26). La lame (12) est pourvue de trois arêtes effilées (28, 30, 32) ayant chacune une face de coupe (34) qui sous-tend un angle d'au moins 90 degrés. Chaque face de coupe (34) est en biais par rapport aux faces de coupe (34) des autres arêtes. L'orientation des faces de coupe (34) des arêtes effilées (28, 30, 32) permet à la lame (12) de produire un effet de portance lorsqu'elle tourne autour d'un matériau sur un axe dans un ensemble d'excavation.
