Abstract

Frame assemblies for a corn row head formed from components formed from different materials may include a frame portion having a first beam leg and a second beam leg formed of a first material and a skid plate attached to each of the first beam leg and the second beam leg formed from a second material different than the first material. The first material may be aluminum, and the second material may be steel. In some implementations, a breast plate joining the first beam leg and the second beam leg may be formed from the first material and may be welded to the first beam leg and the second beam leg. In other implementations, the breast plate may be formed from the second material and may be adhesively bonded to the first and second beam legs.

First claim

What is claimed is:

1. A corn row head comprising:
a stalk roll assembly, the stalk roll assembly comprising:
a frame portion comprising:
a first beam leg including a first end and a second end and formed of a first material;
a second beam leg including a first end and a second end and formed from the first material;
a breast plate coupled to the second ends of the first beam leg and the second beam leg;
a first skid plate coupled to the first end of the first beam leg; and
a second skid plate coupled to the first end of the second beam leg, the first skid plate and the second skid plate formed of a second material different than the first material,

wherein the first material is aluminum, and wherein the second material is steel.

2. The corn row head of claim 1 , wherein the first skid plate and the second skid plate are coupled to the first beam leg and the second beam leg, respectively, with an adhesive.

3. The corn row head of claim 1 , wherein the first beam leg comprises a first portion and a second portion, and wherein the first portion and the second portion are coupled together with a stiffener formed from the second material.

4. The corn row head of claim 1 , wherein the breast plate comprises the second material, and wherein the breast plate is attached to the first beam leg and the second beam leg with an adhesive.

5. The corn row head of claim 4 , wherein the first beam leg comprises a laterally-extending portion formed at the second end of the first beam leg, and wherein the laterally extending portion overlaps a central portion of the breast plate.

6. The corn row head of claim 5 , further comprising a doubler plate that overlays a portion of the first beam leg at the second end of the first beam leg such that the doubler plate, the breast plate, and the first beam leg form a three-layered structure.

7. The corn row head of claim 1 , wherein the breast plate is formed from the second material and comprises a base portion and a side portion angularly extending from the base portion,
wherein the first beam leg comprises a first side portion and a second side portion, the first side portion and the second side portion defining an angle, and
wherein the breast plate overlays the first beam leg such that the side portion of the breast plate overlays an exterior surface of the first side portion of the first beam leg and the base portion of the breast plate overlays an exterior surface of the second side portion of the first beam leg.

8. The corn row head of claim 7 , further comprising a doubler plate overlaying the side portion of the breast plate such that the side portion of the breast plate, the first side portion of the first beam leg, and the doubler plate forms a three-layered structure.

9. The corn row head of claim 7 , wherein the doubler plate is attached to the side portion of the breast plate with an adhesive and wherein the side portion of the breast plate is attached to the first side portion of the first beam leg with the adhesive.

10. The corn row head of claim 1 , wherein the breast plate is formed from the first material, and wherein the first beam leg and the second beam leg are welded to the breast plate.

11. A stalk roll assembly of a corn row head, the stalk roll assembly comprising:
a frame assembly comprising:
a first beam leg formed of a first material;
a second beam leg formed of the first material;
a first skid plate formed of a second material adhesively attached to a first end of the first beam leg; and
a second skid plate formed of the second material adhesively attached to a first end of the second beam leg,

wherein the first beam leg comprises a first casting, the first casting forming an I-beam cross-section at a first end, the I-beam cross-section comprising:
a first flange;
a second flange; and
a web formed between the first flange and the second flange,

wherein the first skid plate is attached to the first flange of the first casing.

12. The stalk roll assembly of claim 11 , wherein the first material is aluminum and wherein the second material is steel.

13. The stalk roll assembly of claim 11 ,
wherein the second beam leg comprises a second casting, the second casting forming an I-beam cross-section at a first end, the I-beam cross-section comprising:
a first flange;
a second flange; and
a web formed between the first flange and the second flange,

wherein the first skid plate is attached to the first flange of the first casing, and
wherein the second skid plate is attached to the first flange of the second casting.

14. The stalk roll assembly of claim 11 , wherein the first skid plate and the second skid plate are attached to the first beam leg and the second beam leg, respectively, with one or more fasteners.

15. A method of manufacturing a frame portion of a stalk roll assembly of a corn row head, the method comprising:
forming a first beam leg from a first material, the first beam leg comprising a first end and a second end;
forming a second beam leg from a second material, the second beam leg comprising a first end and a second end;
coupling the first beam leg and the second beam leg;
attaching a stiffener comprising an end portion to the first beam leg to form a gap between the first beam leg and the end portion of the stiffener;
positioning an end piece in the gap;
attaching the end piece to the first leg and the end portion of the stiffener; and
attaching, with an adhesive, a contact plate to the end piece,
wherein the first material is aluminum and wherein the second material is steel.

16. The method of claim 15 , further comprising:
forming a breast plate from the first material; and
attaching the breast plate to the second ends of the first beam leg and the second beam leg.

17. The method of claim 16 , wherein attaching the breast plate to the second ends of the first beam leg and the second beam leg comprises welding the breast plate to the second ends of the first beam leg and the second beam leg.

18. The method of claim 15 , further comprising:
forming a breast plate from the second material; and
attaching the breast plate to the second ends of the first beam leg and the second beam leg with an adhesive.
