Abstract
A bubble up auger includes a tubular housing, a screw auger and a baffle. The tubular housing includes an inlet opening having a first width end adjacent a first end of the tubular housing and a second width end opposite the first width end. The baffle extends from the inlet opening, outwardly from the central longitudinal axis of the tubular housing and towards the first end of the tubular housing.
Claims11
A crop conveying system for conveying crop material on an
- agricultural combine comprising:
- a crop material elevator for generating a crop material output therefrom;
- a chamber receiving said crop material output;
- a tubular housing having:
- a central longitudinal axis;
- a first end positioned adjacent to the crop material elevator and into said chamber for receiving crop material from the crop material elevator and a second end opposite the first end,
- an inlet opening in the tubular housing at the first end of the tubular housing, said inlet opening being positioned for receiving the crop material output from the crop material elevator, the inlet opening having:
- a first width end adjacent the first end of the tubular housing, a second width end opposite the first width end and spaced from the first width end along a length of the tubular housing, and
- a length from the first width end to the second width end in the direction of the central longitudinal axis;
- and
- an outlet opening about the second end for discharging crop material;
- a screw auger within the tubular housing for conveying crop material between the first and second ends;
- and
- a baffle extending from an outside surface of the tubular housing adjacent the second width end of the inlet opening and in said chamber, the baffle extending outwardly from the tubular housing and the central longitudinal axis of the tubular housing and towards the first end of the tubular housing;
- wherein the inlet opening is rectangular shaped and has a length about 35% to 45% of an overall length of the tubular housing.

An agricultural harvester comprising:
- a harvester frame;
- a crop material elevator connected to the frame for generating a crop material output therefrom;
- a chamber receiving said crop material output;
- a tank for holding crop material connected to the frame;
- a tubular housing connected to the frame and positioned to receive crop material from the crop material elevator, the housing comprising:
- a first end positioned adjacent said crop material elevator and into said chamber and a second end opposite the first end,
- an inlet opening in a length portion of the tubular housing at the first end of the tubular housing for receiving a flow of crop material from the crop material elevator, the inlet opening having a length between a proximal end thereof adjacent the first end of the tubular housing and a distal end thereof opposite the proximal end and between the proximal end and the second end of the tubular housing;
- and
- an outlet opening about the second end for discharging crop material to the tank;
- a screw auger within the tubular housing for conveying crop material between the first and second ends;
- and
- a baffle extending from the tubular housing adjacent the distal end of the inlet opening and in said chamber, the baffle extending both outwardly from a central longitudinal axis of the tubular housing and towards the first end of the tubular housing and spanning a portion of the distance between the proximal and distal ends of the inlet opening;.
- wherein the inlet opening is rectangular shaped and has a length about 35% to 45% of an overall length of the tubular housing.
