Abstract

An agricultural harvester includes an auger assembly including an auger having an auger shaft defining an axis of rotation and a fighting carried by the auger shaft, the auger being configured to rotate the fighting in a sweeping path about the axis of rotation and convey cleaned crop material toward the crop material elevator; an auger trough placed adjacent to the auger to hold crop material in the sweeping path; and an auger cover held above the sweeping path that is configured to direct flung crop material toward the auger and/or the auger trough.

First claim

What is claimed is:

1 . An agricultural harvester, comprising:
a chassis; a cleaning system carried by said chassis and configured to clean crop material; a crop material elevator carried by said chassis and supplied with cleaned crop material from said cleaning system; and an auger assembly carried by said chassis and configured to supply cleaned crop material from said cleaning system to said crop material elevator, said auger assembly including:
an auger having an auger shaft defining an axis of rotation and a flighting carried by said auger shaft, said auger being configured to rotate said fighting in a sweeping path about said axis of rotation and convey cleaned crop material toward said crop material elevator;
an auger trough placed adjacent to said auger to hold crop material in said sweeping path; and
an auger cover held above said sweeping path and configured to direct flung crop material toward at least one of said auger and said auger trough.

2 . The agricultural harvester according to claim 1 , wherein said auger cover has a substantially arced shape.

3 . The agricultural harvester according to claim 1 , wherein said auger assembly includes a first side wall and a second side wall, said auger shaft and said auger cover both being mounted to at least one of said first side wall and said second side wall.

4 . The agricultural harvester according to claim 1 , wherein said auger trough and said auger cover define a front crop material opening and a rear crop material opening therebetween.

5 . The agricultural harvester according to claim 1 , wherein said flighting defines a flighting length and said auger cover is held above an entirety of said flighting length.

6 . The agricultural harvester according to claim 1 , wherein said auger cover defines a symmetrical shape.

7 . The agricultural harvester according to claim 6 , wherein said auger cover is asymmetrically held above said sweeping path.

8 . The agricultural harvester according to claim 1 , wherein said auger assembly has a first side wall and said crop material elevator has a boot portion mounted to said first side wall by at least one bolt, said at least one bolt also mounting said auger cover to said first side wall.

9 . The agricultural harvester according to claim 1 , wherein said cleaning system includes a cleaning fan that produces a forced gas stream defining a blowing path, said auger cover being configured such that crop material flung by said auger does not enter said blowing path.

10 . An auger assembly for an agricultural harvester, comprising:
an auger having an auger shaft defining an axis of rotation and a flighting carried by said auger shaft, said auger being configured to rotate said fighting in a sweeping path about said axis of rotation and convey cleaned crop material toward said crop material elevator; an auger trough placed adjacent to said auger to hold crop material in said sweeping path; and an auger cover held above said sweeping path and configured to direct flung crop material toward said auger trough.

11 . The auger assembly according to claim 10 , wherein said auger cover has a substantially arced shape.

12 . The auger assembly according to claim 10 , wherein said auger assembly includes a first side wall and a second side wall, said auger shaft and said auger cover both being mounted to at least one of said first side wall and said second side wall.

13 . The auger assembly according to claim 10 , wherein said auger trough and said auger cover define a front crop material opening and a rear crop material opening therebetween.

14 . The auger assembly according to claim 10 , wherein said flighting defines a fighting length and said auger cover is held above an entirety of said fighting length.

15 . The auger assembly according to claim 10 , wherein said auger cover defines a symmetrical shape.

16 . The auger assembly according to claim 15 , wherein said auger cover is asymmetrically held above said sweeping path.
