Abstract
A v-shaped wear strip includes a v-shaped body defining a longitudinal axis, a first end, and a second end disposed along the longitudinal axis. The v-shaped body includes a first attachment portion defining a first aperture, a first pressing portion that forms a first oblique angle with the first attachment portion at the first end, and a first arcuate portion transitioning from the first attachment portion to the first pressing portion at the first end.
Claims19
A mounting assembly for attaching a board assembly or a blade assembly to a grading machine, the mounting assembly comprising:
- a jaw member defining a Y-shaped slot defining a vertical direction, a horizontal direction, and a longitudinal axis, the jaw member forming a first wear strip attachment portion that extends vertically, and a first angled wear strip support portion that forms a first obtuse angle with the first wear strip attachment portion;
- and
- a first v-shaped wear strip including a first attachment leg defining a first fastener receiving aperture extending horizontally through the first attachment leg, and a first pressing leg that is configured to press onto a board assembly or a blade assembly for holding the board assembly or the blade assembly to the grading machine;
- wherein the first wear strip attachment portion of the jaw member defines a first mounting aperture that extends horizontally and that is aligned with the first fastener receiving aperture of the first v-shaped wear strip.
A v-shaped wear strip for use with a mounting assembly of a grading machine, the v-shaped wear strip comprising:
- a v-shaped body defining a longitudinal axis, a first end, and a second end disposed along the longitudinal axis, the v-shaped body including
- a first attachment portion;
- a first pressing portion that forms a first oblique angle with the first attachment portion at the first end;
- and
- a first arcuate portion transitioning from the first attachment portion to the first pressing portion at the first end;
- and
- wherein the first oblique angle ranges from 130 degrees to 140 degrees, the v-shaped body comprises a metallic material, the first attachment portion defines a minimum thickness measured along a direction perpendicular to the longitudinal axis at the first end ranging from 3 mm to 10 mm, the first arcuate portion defines a convex radius of curvature at the first end ranging from 13 mm to 20 mm, and the v-shaped body defines a longitudinal length measured along the longitudinal axis from the first end to the second end ranging from 150 mm to 500 mm.
A method for mounting or demounting a plurality of v-shaped wear strips to a jaw member of a mounting assembly for attaching a blade assembly or a board assembly to a machine, the method comprising:
- inserting a first fastener into a first mounting aperture of the jaw member;
- inserting the first fastener into a first fastener receiving aperture of a first said v-shaped wear strip;
- inserting the first fastener into a second fastener receiving aperture of a second said v-shaped wear strip;
- and
- inserting the first fastener into a second mounting aperture of the jaw member at a first end of the jaw member.
