Abstract

A forage harvester row crop header having fore-and-aft dividers defining elongated passageways therebetween is provided with a rotary member disposed within a pocket defined in a rear portion of one of the outboard dividers to assist in the feeding of crop along the passageway. The rotary member is capstan shaped having its axis of rotation inclined upwardly and rearwardly with respect to the top surface of the respective outboard divider. The lower surface of the rotary member forms a smooth transition with the top surface of the divider and thus, in profile, the divider and the rotary member are represented by a line which gradually slopes, from the forward end of the divider upwardly and rearwardly and therefrom smoothly contours upwardly and rearwardly a short distance and therefrom upwardly and forwardly, thereby providing a substantially uninterrupted surface for the flow of draped over crop along the divider and the rotary member. The rotary member is power driven to feed the crop inwardly toward the passageway.

Claims

1. In a row crop means for a mobile harvesting unit adapted to advance over a field of crop planted in rows, said means including a frame, laterally spaced generally fore-and-aft gathering members mounted on the frame defining at least one elongated fore-and-aft passageway adapted to receive a row of crop as the unit advances, each of said gathering members adapted to move crop rearwardly along the passageway to feed the crop to said unit, at least one of said gathering members having a relatively smooth upwardly and rearwardly inclined top surface adapted to slideably engage down crop as the unit advances, the improvement comprising:

a rotary member disposed in a rear portion of at least one of said gathering members for assisting in the feeding of said down crop being draped over said member to said unit, said at least one gathering member having a cut-away portion on the rearward end thereof forming a recess area for positioning said rotary member such that the lower portion of said rotary member forms a substantially continuous path extending from said top surface of said at least one gathering member for the sliding of said draped-over crop rearwardly and upwardly from said member and onto said rotary member.

2. The row crop means as described in claim 1, wherein the rotary member is inclined upwardly and rearwardly with respect to the top surface of said gathering member.

3. The row crop means as described in claim 1, wherein the lower portion of said rotary member, from the bottom end thereof, slopes upwardly and tapers inwardly.

4. The row crop means as described in claim 1, wherein the lower portion of said rotary member forms a smooth transitional path for the flow of draped-over crop over the top surface of said gathering member and up and along said rotary member.

5. The row crop means as described in claim 1, wherein the upper portion of said rotary member, from the top end thereof, slopes downwardly and tapers inwardly such that said crop is prevented from moving up and over said rotary member.

6. The row crop means as described in claim 1, wherein said rotary member is capstan shaped.

7. The row crop means as described in claim 1, wherein the profile of said gathering member together with said rotary member is represented by a line which gradually slopes, from the forward end of said gathering member, upwardly and rearwardly and therefrom smoothly contours upwardly and rearwardly a short distance and therefrom upwardly and forwardly, thereby providing a substantially uninterrupted surface for the flow of draped over crop along said gathering member and said rotary member.

8. The row crop means as described in claim 1, wherein the axis of said rotary member is canted inwardly toward said passageway such that an upper portion of said rotary member is closer to said passageway then its lower portion.

9. In a row crop means for a mobile harvesting unit adapted to advance over a field of crop planted in rows, said means including, laterally spaced generally fore-and-aft gathering members mounted on the frame and defining at least one elongated fore-and-aft passageway adapted to receive crop as the unit advances, each of said gathering members adapted to move crop rearwardly along the passageway to feed the crop to said unit, at least one of said gathering members having a relatively smooth upwardly and rearwardly inclined top surface adapted to slideably engage down crop as the unit advances;

the improvement comprising;

a rotary member disposed in a rear portion of at least one of said gathering members for assisting in the feeding of said down crop being draped over said member to said unit, said at least one gathering member having a pocket defined at the rearward end thereof by a downwardly and rearwardly sloping surface on which said rotary member is mounted so as to provide a rotating surface which is substantially a continuation of the top surface of said gathering member but increasing in slope such that the draped crop which moves rearwardly over the top surface of said gathering member continues upwardly on said rotary member which is adapted to rotate in a direction causing said crop to move rearwardly along said passageway.

10. The row crop means as described in claim 9, wherein the lower portion of said rotary member, from the bottom end thereof, slopes upwardly and tapers inwardly.

11. The row crop means as described in claim 9, wherein the lower portion of said rotary member forms a smooth transitional path for the flow of draped over crop over the top surface of said gathering member and up and along said rotary member.

12. The row crop means as described in claim 9, wherein the upper portion of said rotary member, from the top end thereof, slopes downwardly and tapers inwardly such that said crop moving up and along said rotary member is prevented from moving over the top of said rotary member.

13. The row crop means as described in claim 9, wherein the axis of said rotary member is canted inwardly toward said passageway such that the upper portion of said rotary member is closer to said passageway then its lower portion.

14. A row crop gathering head for a forage harvester unit comprising:

a. a frame having a discharge opening defined therein for the passage of crop from said gathering head into said harvester unit;

b. a plurality of crop dividers mounted on said frame and defining at least one crop passageway, at least one of said dividers having an upper edge surface angling upwardly from its front end towards its rear end, thereby providing a crop guiding surface for crop drapped over said divider as said unit advances forwardly over a field of row crops;

c. gathering conveyors respectively disposed on opposite sides of said passageway for engaging crop therein and moving the same rearwardly along said passageway; and

d. a rotary member mounted adjacent the rear end of said at least one divider and being inclined such that its lower portion forms a transition with the top surface of said at least one divider such that crop sliding over said top surface are not interrupted as the same are moved rearwardly along said passageway to said discharge opening.

15. The row crop gathering head as described in claim 14, wherein said rotary member is inclined upwardly and rearwardly with respect to the top surface of said divider.

16. The row crop gathering head as described in claim 14, wherein the upper portion of said rotary member from the top thereof slopes downwardly and tapers inwardly such that said crop is prevented from moving over the top of said rotary member.

17. The row crop gathering head as described in claim 14, wherein the axis of said rotary member is canted inwardly toward said passageway such that an upper portion of said rotary member is closer to said passageway than its lower portion.

18. A row crop unit for a forage harvester or the like adapted to be moved forwardly over a field of row crop comprising:

a. a frame having a rear discharge opening for the introduction of crop material to said harvester,

b. a plurality of fore-and-aft dividers mounted on the frame and defining at least one elongated passageway for receiving stalks of crops as the unit advances over the field, at least one of said dividers having a top surface which gradually slopes upwardly and rearwardly and then bends downwardly and rearwardly for a short distance and then upwardly and rearwardly to a top portion of said frame thereby forming a pocket in said top surface of said one divider,

c. a rotary member disposed within said pocket of said one divider having its axis of rotation generally perpendicular to the rearward downwardly sloping portion of said top surface of said one divider and having its outer surface meeting with the top surface of said one divider to thereby form a rearward and upwardly inclined continuous path for the sliding over of down crop stalks toward said discharge opening.

19. The row crop unit as described in claim 18, wherein said rotary member is hour-glassed shaped.
