WIPO Patent Application WO/2020/054640
Kind Code:
A1
Abstract:
A bucket (50) is coupled to an arm (17) of a work machine (12) so as to be able to rotate around a central axis (110). The bucket (50) comprises a bottom plate (60) that has a first deepest portion (62), a bracket (86) that is provided on the back face of the bottom plate (60), and a front lip (72). The bottom plate (60) has a first inclined portion (67) on the side where the bracket (86) is mounted. A first reference line (121) is stipulated to pass through the central axis (110) and the distal end (73) of the front lip (72), and a second reference line (122) is stipulated to be orthogonal to the first reference line (121) and pass through the first deepest portion (62). An angle (β) formed by the second reference line (122) and the front lip (72) is smaller than an angle (α) formed by the second reference line (122) and the first inclined portion (67). The location of the intersection (P) of the first reference line (121) and the second reference line (122) is near the front lip (72) on the first reference line (121).
