Abstract

A wear plate assembly for a ground engaging system. The wear plate assembly includes a wear plate, a connection plate, and a lock cavity. The wear plate has a back surface and a front surface spaced from the back surface along a first direction. The connection plate extends from the front surface at least partially in the first direction. The connection plate has an inner surface and an outer surface spaced from the inner surface along a second direction. The lock cavity is formed by the connection plate. The lock cavity extends from a first opening that opens to the inner surface to a second opening that opens to the outer surface. The first opening has a first diameter and the second opening has a second diameter that is smaller than the first diameter.

First claim

We claim:

1. A wear plate assembly comprising:
a wear plate having a first portion, a second portion spaced from the first portion along a first direction, a back surface, and a front surface spaced from the back surface along a second direction that is substantially perpendicular to the first direction, wherein the back surface and the front surface extend between the first portion and the second portion;
a connection plate extending from the front surface at least partially in the second direction, the connection plate having an inner surface and an outer surface spaced from the inner surface along a third direction; and
a lock cavity formed by the connection plate, the lock cavity extending from a first opening that opens to the inner surface to a second opening that opens to the outer surface, wherein the first opening has a first diameter and the second opening has a second diameter that is smaller than the first diameter.

2. The wear plate assembly of claim 1 , further comprising a slide lock member coupled to the front surface of the wear plate, the slide lock extending in the first direction.

3. The wear plate assembly of claim 2 , wherein the slide lock member is positioned adjacent to the first portion.

4. The wear plate assembly of claim 3 , wherein the slide lock member has a t-shaped cross section.

5. The wear plate assembly of claim 1 , further comprising a second connection plate extending from the front surface at least partially in the second direction, the second connection plate having a second inner surface and a second outer surface spaced from the second inner surface along a fourth direction, wherein a second lock cavity is formed by the second connection plate, the lock cavity extending from a third opening that opens to the second inner surface to a fourth opening that opens to the second outer surface, wherein the third opening has a third diameter and the fourth opening has a fourth diameter that is smaller than the third diameter.

6. The wear plate assembly of claim 5 , wherein the connection plate and the second connection plate are positioned adjacent to the first portion of the wear plate.

7. The wear plate assembly of claim 6 , wherein the third direction and the fourth direction are substantially perpendicular to both the first direction and the second direction.

8. The wear plate assembly of claim 1 , further comprising a rotatable lock positioned within the lock cavity, the rotatable lock configured to rotate between an unlocked position and a locked position, the rotatable lock including a slot configured to receive a post within, wherein when the post is received within the slot and when the lock is in the locked position the post is prevented from moving from the slot.

9. The wear plate assembly of claim 1 , wherein the distance between the back surface and the front surface is less than or equal to 45 millimeters.
