Abstract

A cart having an adjustable elevation auger. A junction box may located within the opening of a sump of a bin of a cart. The junction box may have an open top, closed bottom and sides, and back wall. The back wall of the junction box may be secured to a bin wall by a hinge such that the junction box may pivot about a pivot axis. An auger housing may be connected to and extend from the junction box. An auger may extend through the auger housing and have an intake end disposed within the junction box. The auger housing and auger may pivot with the junction box about a pivot axis between a lowered position and an elevated position. The auger may be a corner auger and may be a folding auger.

First claim

The invention claimed is:

1. A cart comprising:
a frame supported on a plurality of wheels;
a bin supported on said frame and including a plurality of bin walls defining a storage space for agricultural material;
an auger housing coupled to the bin and having an intake end configured to receive agricultural material from the bin, the auger housing having a lower auger housing section and an upper auger housing section, wherein said upper and lower auger housing sections of said auger housing are pivotally connected together such that said upper auger housing section pivots about a first pivot axis between stored and operating positions of said auger housing;
upper and lower augers extending through said upper and lower auger housing sections, respectively;
a discharge spout at a top end of said upper auger housing section;
a lift assembly connected with said auger housing and movable to cause said auger housing in said operating position to pivot about a second pivot axis between a lowered position in which said discharge spout is disposed at a first elevation and an elevated position in which said discharge spout is disposed at a second elevation higher than said first elevation; and
wherein said first and second pivot axes are oriented at different angles relative to a longitudinal axis of said auger housing,
wherein said upper auger housing section is configured to be disposed along an outer surface of said bin when said auger housing is in said stored position, and
wherein said upper auger housing section is movable in only two directions of freedom, about said first and second pivot axes.

2. The cart of claim 1 , wherein said upper auger housing section is movable in response to said auger housing pivoting about said second pivot axis.

3. The cart of claim 1 , wherein both said upper and lower auger housing sections are movable in response to said auger housing pivoting about said second pivot axis.

4. The cart of claim 1 , wherein said first and second pivot axes are spaced from one another along a longitudinal axis of said auger housing.

5. The cart of claim 1 , wherein said first and second pivot axes are spaced from one another along a longitudinal axis of said lower auger housing section.

6. The cart of claim 1 , wherein said first and second pivot axes are oriented at different angles relative to a longitudinal axis of said lower auger housing section.

7. The cart of claim 1 , wherein said second pivot axis is located above a central axis of said lower auger when said auger housing is in both said lowered and elevated positions.

8. The cart of claim 1 , wherein said lift assembly further includes a piston connected between the frame and the auger housing and wherein said piston is configured to be controlled remotely from a cab of a tractor.

9. The cart of claim 1 , wherein said first pivot axis is above said second pivot axis when said auger housing is in each of said stored, operating, lowered, and elevated positions.

10. A cart comprising:
a frame supported on a plurality of wheels;
a bin supported on said frame and including a plurality of bin walls defining a storage space for agricultural material;
an auger housing coupled to said bin and having an intake end configured to receive agricultural material from said bin, said auger housing having a lower auger housing section and an upper auger housing section, wherein said lower auger housing section is pivotally secured to the upper auger housing section such that the upper auger housing section is pivotable about a first pivot axis between an operating position of said auger housing, in which said upper auger housing section is substantially in alignment with said lower auger housing section, and a stored position of said auger housing, in which said upper auger housing section extends along an outer surface of the bin;
upper and lower augers extending through said upper and lower auger housing sections, respectively;
a discharge spout at a top end of said upper auger housing section;
a lift assembly connected with said auger housing and movable to cause said auger housing in said operating position to pivot about a second pivot axis independent of any movement of said bin and between a lowered position in which said discharge spout is disposed at a first elevation and an elevated position in which said discharge spout is disposed at a second elevation higher than said first elevation;
wherein said first and second pivot axes are oriented at different angles relative to a longitudinal axis of said auger housing, and
wherein said upper auger housing section is movable in only two directions of freedom, about said first and second pivot axes.

11. The cart of claim 10 , wherein said first and second pivot axes are spaced from one another along a longitudinal axis of said auger housing.

12. The cart of claim 10 , wherein said first and second pivot axes are spaced from one another along a longitudinal axis of said lower auger housing section.

13. The cart of claim 10 , wherein said first and second pivot axes are oriented at different angles relative to a longitudinal axis of said lower auger housing section.

14. The cart of claim 10 , wherein said second pivot axis is located above a central axis of said lower auger when said auger housing is in both said lowered and elevated positions.

15. The cart of claim 10 , wherein said lift assembly further includes a piston connected between the frame and the auger housing and wherein said piston is configured to be controlled remotely from a cab of a tractor.

16. The cart of claim 10 , wherein said first pivot axis is above said second pivot axis when said auger housing is in each of said stored, operating, lowered, and elevated positions.

17. A cart comprising:
a frame supported on a plurality of wheels;
a bin supported on said frame and including a plurality of bin walls defining a storage space for agricultural material, including a first side wall and a second side wall connected to said first side wall;
an auger housing coupled to said bin at a corner of said bin defined as a region where said first side wall and said second side wall meet and having an intake end configured to receive agricultural material from said bin, said auger housing having a lower auger housing section and an upper auger housing section, wherein said lower auger housing section is pivotally secured to the upper auger housing section such that the upper auger housing section is pivotable about a first pivot axis between an operating position of said auger housing, in which said upper auger housing section is substantially in alignment with said lower auger housing section, and a stored position of said auger housing, in which said upper auger housing section extends along an outer surface of the bin;
upper and lower augers extending through said upper and lower auger housing sections, respectively;
a discharge spout at a top end of said upper auger housing section;
a lift assembly connected with said auger housing and movable to cause said auger housing in said operating position to pivot about a second pivot axis between a lowered position in which said discharge spout is disposed at a first elevation and an elevated position in which said discharge spout is disposed at a second elevation higher than said first elevation; and
wherein said first and second pivot axes are oriented at different angles relative to a longitudinal axis of said auger housing.

18. The cart of claim 17 , wherein said lift assembly further includes a piston connected between the
