Abstract

A corn harvesting header ( 24 ) includes a powered row unit ( 38 ) and a gathering hood ( 98 ). The row unit ( 38 ) defines a longitudinal crop row path that extends in a generally rearward crop travel direction and receives a corn row as the header ( 24 ) is advanced along the corn row. The gathering hood ( 98 ) partly overlies the row unit ( 38 ) and includes a laterally extending dam ( 132 ) that restricts corn from moving forwardly. The dam ( 132 ) at least partly defines a gutter to receive corn kernels and direct the corn kernels rearwardly.

First claim

What is claimed is:

1 . A corn harvesting header operable to harvest a row of corn, said corn harvesting header comprising:
a powered row unit defining a longitudinal crop row path that extends in a generally rearward crop travel direction and receives the corn row as the header is advanced along the corn row, with the row unit operable to move corn in the crop travel direction; and a gathering hood partly overlying the row unit and presenting forward and aft ends, said gathering hood including an outer wall that presents an exposed gathering surface positioned laterally adjacent the crop row path and extending longitudinally between the ends, with at least part of the gathering surface being slanted downwardly toward the crop row path to generally direct corn into the crop row path, said gathering hood further including a laterally extending dam that projects upwardly from the outer wall adjacent the forward end to restrict corn from moving forwardly along the gathering surface, with the dam and the outer wall cooperatively defining a gutter to receive corn kernels, said dam including a central section and an end section spaced from the central section in the crop travel direction so that the gutter directs corn kernels rearwardly.

2 . The corn harvesting header as claimed in claim 1 ,
said dam including a transition section that interconnects the central section and the end section so that the gutter extends continuously between the sections.

3 . The corn harvesting header as claimed in claim 2 ,
said transition section and said central section cooperatively defining an obtuse included angle.

4 . The corn harvesting header as claimed in claim 1 ,
said gathering surface including a generally central surface and side surfaces located on opposite sides of the central surface, said central surface having a convex shape along a transverse cross-section and being positioned so that the central surface directs corn kernels toward at least one of the side surfaces.

5 . The corn harvesting header as claimed in claim 4 ,
said gathering surface including a rear surface positioned rearwardly of the central surface to direct corn kernels rearwardly of the gathering hood.

6 . The corn harvesting header as claimed in claim 4 ,
said central surface including a centrally located hump portion that projects from the dam, said hump portion being raised relative to a remaining portion of the central surface.

7 . The corn harvesting header as claimed in claim 1 ,
said row unit including a pair of adjacent deck plates that cooperatively define a longitudinal crop-receiving deck plate opening extending along the crop row path and sized to receive stalks of corn, with the deck plate opening presenting a width dimension, said deck plates cooperatively defining a forwardmost converging region along which the width dimension tapers in the crop travel direction, with the converging region presenting a rear margin that defines a restricted width dimension; and said gutter presenting an end margin that is located adjacent the rear margin of the converging region to direct corn kernels rearwardly of the converging region.

8 . The corn harvesting header as claimed in claim 1 ; and
a snout extending forwardly of the gathering hood and operable to direct the corn row into the row path, said snout presenting a forward tip end and an exposed snout surface that tapers forwardly toward the tip end.

9 . The corn harvesting header as claimed in claim 8 ,
said snout and said gathering hood being coaxially aligned and pivotally attached to one another, with the snout being pivotal relative to the gathering hood into and out of a lowermost position.

10 . The corn harvesting header as claimed in claim 9 ,
said snout presenting an aft opening that at least partly receives the forward end of the gathering hood so that the snout overlaps the gathering hood.

11 . The corn harvesting header as claimed in claim 10 ,
said aft opening of the snout receiving the central section of the dam, with the end section being located rearwardly of the snout.

12 . The corn harvesting header as claimed in claim 11 ,
said snout being pivotal relative to the gathering hood into and out of an uppermost position, said end section of the dam engaging the snout in the uppermost position to restrict upward movement of the snout beyond the uppermost position.
