Abstract

A wearing-part arrangement for a leading edge of a soil-working implement includes a point configured to be releasably attached to the soil-working implement. The point has a pointed front portion and a transverse elevation projecting from an upper face thereof. At least the front portion is mirror-symmetrical around a longitudinal axis of the point and has first and second oblique faces diverging in a direction of a socket on the point and merging with a first side edge surface and a second side edge surface. The first oblique face is bounded by a first cutting edge, and the second oblique face is bounded by a second cutting edge. When the point is attached to the soil-working implement, at least a rear portion of the second oblique face and the second side edge surface adjacent to the second oblique face project beyond a side edge of the soil-working implement.

Claims

1. A wearing-part arrangement for a leading edge of a soil-working implement, the wearing-part arrangement comprising:

a point configured to be releasably attached to the soil-working implement, the point having a pointed front portion,

wherein at least the front portion is mirror-symmetrical around a longitudinal axis of the point and has a first oblique face and a second oblique face diverging in a direction of a socket on the point and merging with a first side edge surface and a second side edge surface,

wherein the first oblique face is bounded by a first cutting edge, and the second oblique face is bounded by a second cutting edge,

wherein when the point is attached to the soil-working implement, at least a rear portion of the second oblique face and the second side edge surface adjacent to the second oblique face project beyond a side edge of the soil-working implement, and

wherein the point includes a transverse elevation projecting from an upper face thereof.

2. The wearing-part arrangement in accordance with claim 1, wherein a longitudinal axis of the first oblique face is parallel to the leading edge or a front portion of the leading edge.

3. The wearing-part arrangement in accordance with claim 1, wherein the point is releasably attached to the soil-working implement by a quick-release coupling device.

4. The wearing-part arrangement in accordance with claim 1, wherein a thickness of the point gradually decreases towards the first cutting edge and the second cutting edge.

5. A wearing-part arrangement for a leading edge of a soil-working implement, the wearing-part arrangement comprising:

a point configured to be releasably attached to the soil-working implement, the point having a pointed front portion; and

a wearing-part holder configured to be releasably attached to a surface of the soil-working implement, the wearing-part holder being configured to receive the point,

wherein at least the front portion is mirror-symmetrical around a longitudinal axis of the point and has a first oblique face and a second oblique face diverging in a direction of a socket on the point and merging with a first side edge surface and a second side edge surface,

wherein the first oblique face is bounded by a first cutting edge, and the second oblique face is bounded by a second cutting edge,

wherein when the point is attached to the soil-working implement, at least a rear portion of the second oblique face and the second side edge surface adjacent to the second oblique face project beyond a soil-working implement side edge, and

wherein the point includes a transverse elevation configured to shield the wearing-part holder from wear, the transverse elevation projecting from an upper face of the point.

6. The wearing-part arrangement in accordance with claim 5, wherein the wearing-part holder has a curved abutment surface configured to rest against a portion of the surface of the soil-working implement.

7. The wearing-part arrangement in accordance with claim 6, wherein the abutment surface is single-curved around an axis which is parallel to the longitudinal axis of the point.

8. The wearing-part arrangement in accordance with claim 6, wherein the abutment surface is single-curved around an axis which is parallel to the longitudinal axis of the point, and has a radius that is smaller than a corresponding radius of curvature of the surface of the soil-working implement.

9. The wearing-part arrangement in accordance with claim 5, wherein the wearing-part holder includes an attachment pin that complements and mates with the socket of the point.

10. The wearing-part arrangement in accordance with claim 9, wherein the point is releasably attached to the soil-working implement by a quick-release coupling device comprised of the attachment pin and the socket.

11. The wearing-part arrangement in accordance with claim 5, wherein a thickness of the point gradually decreases towards the first cutting edge and the second cutting edge.
