Abstract

A farm implement includes a frame, a container mounted on the frame, a hitch extending away from a front wall of the container in a first direction, and an auger assembly extending away from the front wall. The auger assembly includes a receiving portion coupled to the container, a lower portion coupled to the receiving portion, an upper portion coupled to the lower portion, a joint assembly coupled to both the upper and lower portions, and a discharge portion coupled to the upper portion. The joint assembly allows the upper portion to pivot about a folding axis between a transport position and an operating position. In the operating position, the lower portion is angled toward the hitch relative to a vertical plane extending transverse to a direction of travel by the farm implement, and the lower portion is angularly offset from the upper portion by a second angle.

First claim

What is claimed is:

1. A farm implement comprising:
a frame;
a container mounted on the frame and comprising a front wall, a rear wall, and laterally opposed side walls arranged such that the container defines a space for holding grain;
a hitch extending away from the front wall in a first direction; and
an auger assembly extending away from the front wall and configured to receive grain held in the container and convey the grain out of the container, wherein the auger assembly comprises:
a receiving auger portion disposed proximate to the front wall;
a lower auger portion comprising a lower auger housing extending along a longitudinal axis of the lower auger portion from a first end to a second end, wherein the first end of the lower auger housing is operatively connected to the receiving auger portion;
an upper auger portion comprising an upper auger housing extending along a longitudinal axis of the upper auger portion from a first end to a second end;
a joint assembly coupled to the upper and lower auger portions and defining a folding axis, wherein the upper auger portion is configured to pivot about the folding axis between a transport position and an operating position such that the first end of the upper auger housing abuts the second end of the lower auger housing in the operating position, and the first end of the upper auger housing is spatially separated from the second end of the lower auger housing in the transport position; and
a discharge portion coupled to the second end of the upper auger housing;
wherein the lower auger portion is angled toward the hitch relative to a vertical plane extending transverse to a direction of travel by the farm implement such that a centerline of the lower auger portion is oriented at a first angle relative to the vertical plane;
wherein the lower auger portion is angularly offset from the upper auger portion such that the centerline of the lower auger portion is oriented at a second angle relative to a centerline of the upper auger portion.

2. The farm implement of claim 1 , wherein the first angle ranges from about 5° to about 25°.

3. The farm implement of claim 1 , wherein the first angle is set at about 12°.

4. The farm implement of claim 1 , wherein the second angle ranges from about 10° to about 30°.

5. The farm implement of claim 1 , wherein the second angle is set at about 17.5°.

6. The farm implement of claim 1 , wherein the auger receiving portion is disposed at about a center position along a bottom edge of the front wall.

7. The farm implement of claim 1 , wherein the hitch comprises a tongue and a coupler disposed at an end thereof, and when the upper auger portion is set in the operating position, the auger assembly extends beyond the hitch in the first direction such that the discharge portion is disposed ahead of the tongue and the coupler by a first predetermined distance.

8. The farm implement of claim 7 , wherein the first predetermined distance is set from about 8 inches to 24 inches.

9. The farm implement of claim 7 , wherein the auger receiving portion is aligned with the coupler of the hitch.

10. The farm implement of claim 1 , wherein auger assembly further comprises a pivot member integrated with the lower auger portion, and the pivot member is configured to rotate about a rotational axis extending transverse to the vertical plane such that the auger assembly pivots between a plurality of operating positions.

11. The farm implement of claim 10 , wherein a height between the discharge portion and a ground surface changes as the auger assembly pivots between the plurality of operating positions.

12. The farm implement of claim 11 , wherein the height between the discharge portion and the ground surface ranges from about 10 feet to 20 feet.

13. The farm implement of claim 10 , wherein a side reach between the discharge portion and the rotational axis changes as the auger assembly pivots between the plurality of operating positions.

14. The farm implement of claim 13 , wherein the side reach between the discharge portion and the rotation axis ranges from about 5 feet to about 15 feet.

15. The farm implement of claim 10 , wherein the vertical plane extends through the pivot member.

16. The farm implement of claim 1 , wherein the upper auger housing extends along the front wall in a lateral direction when the upper auger portion is set in the transport position.

17. The farm implement of claim 1 , wherein the centerline of the lower auger portion is defined by the longitudinal axis of lower auger portion or is parallel to the longitudinal axis of the lower auger portion, and the centerline of the upper auger portion is defined by the longitudinal axis of upper auger portion or is parallel to the longitudinal axis of the upper auger portion.

18. The farm implement of claim 1 , wherein the second angle corresponds to a forward component of the angular offset between the upper and lower auger portions such that an angular displacement between the upper and the lower auger portions, as defined by the second angle, extends in the first direction toward the hitch.
