Abstract

A breaker tine comprises a front elongated portion, a rear elongated portion, a nose portion extending from the front elongated portion at an opposite end from the rear elongated portion, and a replaceable ground engaging tool coupled to the nose portion of the breaker tine. The breaker tine may include pins for attaching the ground engaging tool to the breaker tine. The breaker tine may further include a first receiving cavity formed in a first side of the nose portion, and a second receiving cavity formed in a second side of the nose portion, wherein the first receiving cavity is opposite the second receiving cavity but do not communicate or connect with each other.

First claim

We claim:

1. A ground engaging tool system, comprising:
a back frame assembly;
a breaker tine coupled to the back frame assembly, the breaker tine comprising:
a front elongated portion;
a rear elongated portion extending in a direction substantially perpendicular to the front elongated portion;
a nose portion extending from the front elongated portion at an opposite end from the rear elongated portion;
a first plate receiving cavity formed in a first side of the nose portion;
a second plate receiving cavity formed in a second side of the nose portion;
wherein the first plate receiving cavity is opposite the second plate receiving cavity but do not communicate or connect with each other;

a first plate comprising a frustoconically shaped first knob, wherein the first plate is configured to fit into the first plate receiving cavity;
a replaceable ground engaging tool coupled to the nose portion of the breaker tine, comprising:
a front end;
a rear end;
a top surface;
a bottom surface;
a first side opposite a second side; and
a nose portion receiving cavity on an interior side.

2. The system of claim 1 , wherein the first plate receiving cavity further comprises:
a bottom indent portion;
a top indent portion; and
a ledge parallel to the top surface of the nose portion and disposed between the bottom indent portion and top indent portion.

3. The system of claim 2 , wherein the top indent portion is deeper in a direction towards the second plate receiving cavity than the bottom indent portion.

4. The system of claim 3 , wherein the top indent portion is wider in a direction towards a tip of the nose portion than the bottom indent portion.

5. The system of claim 1 , wherein the first plate further comprises:
a bottom portion;
a top portion; and
a seating portion located between the top portion and the bottom portion.

6. The system of claim 5 , wherein the top portion is thicker than the bottom portion in a direction parallel to a longitudinal axis of the first knob, wherein a width of the bottom portion of the first plate is narrower than a width of the top portion of the first plate, wherein the first knob is frustoconically shaped.

7. The system of claim 6 , wherein the first plate further comprises:
a first tapered projection extending outward from a first side of the top portion of the first plate; and
a second tapered projection extending outward from a second side of the top portion of the first plate opposite the first side.

8. The system of claim 7 , further comprising:
a second plate including a frustoconically shaped second knob, wherein the second plate is configured to fit into the second plate receiving cavity.

9. The system of claim 1 , wherein the ground engaging tool further comprises a bulge extending outward from an exterior surface of the first side of the ground engaging tool, wherein a lock opening extends through the bulge to the nose portion receiving cavity, and wherein a width of the front end of the ground engaging tool extending from the first side to the second side is greater than 1.5 times of a height of the rear end of the ground engaging tool extending from the top surface to the bottom surface of the ground engaging tool.

10. The system of claim 9 , wherein the ground engaging tool further comprises:
a receiving slot formed in an interior surface of a first side of the ground engaging tool and extending between the rear end of the ground engaging tool to the lock opening, where the lock opening extends through the bulge, and wherein the receiving slot is configured to receive the first knob.

11. The system of claim 9 , wherein the ground engaging tool further comprises:
a lock coupled to the lock opening, wherein the first knob is capable of being inserted into an indent in a bottom portion of the lock, and wherein the lock further comprises an indent in a top portion of the lock opposite the bottom portion.

12. The system of claim 6 , wherein a joint is capable of being formed by one or more tapered projections on the first plate interlocking with the first plate receiving cavity.

13. The system of claim 12 , wherein the top portion of the first plate is flush with both the first side and a top surface of the nose portion, and the bottom portion of the first plate is flush with the bottom surface of the nose portion, when the first plate is seated in the first plate receiving cavity.
