Abstract

A chopping assembly for a harvesting implement having a blade assembly, a housing, and a guide. The blade assembly is disposed within the housing and the guide directs cornstalks toward an input port on the housing. The blade assembly not only cuts the cornstalk from its root but also chops the stalk into stover. A fluid dynamic force is created by the blade assembly to direct the stover with the aid of the housing to an output port.

Claims

1. A chopping assembly for a harvesting implement, comprising:

a corn head mounted to a frame;

an arcuate housing mounted to the corn head and having an input port and an output port wherein the top wall of the housing is mounted flush to the corn head'"'"'s bottom surface;

a blade assembly disposed within the arcuate housing; and

an exhaust channel mounted to the housing wherein the exhaust channel extends rearwardly away from the output port of the housing and downwardly offset and spaced away from the corn header'"'"'s bottom surface, to an output port of the exhaust channel.

2. The chopping assembly of claim 1 wherein the exhaust channel is connected to and in communication with the output port of the housing.

3. The chopping assembly of claim 1 further comprising a pair of elongated guide members that are mounted to and extend between the corn head and the housing.

4. The chopping assembly of claim 3 wherein the elongated guide members are positioned on either side of the input port.

5. The chopping assembly of claim 1 further comprising a conveyor positioned adjacent the output port of the exhaust channel at an end of the exhaust channel.

6. The chopping assembly of claim 1 wherein the blade assembly comprises a plurality of blades having teeth.

7. The chopping assembly of claim 1 wherein the housing has a side wall and a bottom wall.

8. The chopping assembly of claim 7 wherein the bottom wall has a slot positioned at the input port.

9. The chopping assembly of claim 1 wherein the blade assembly includes a plurality of blades extending outwardly from a drive shaft.

10. The chopping assembly of claim 1 further comprising the housing having a sidewall that is arcuate.

11. The chopping assembly of claim 1 wherein the housing'"'"'s top wall has an opening such that stover falls through the opening.

12. The chopping assembly of claim 1 wherein the blade assembly is positioned to cut a cornstalk received within the input port from its root and chop the cornstalk into stover, wherein the blade assembly creates a fluid dynamic force to direct the stover through the output port.
