Abstract

A seed carrier includes a main hopper coupled with a frame via leg members. The main hopper has a discharge. A base plate is coupled with the frame. A support arm is rotatably coupled with the base plate at a first end. A belt driven conveyor having a conveyor hopper at a first end and a discharge at a second end is rotatably coupled with a second end of said support arm at an approximate center of gravity thereof. A latch mechanism is provided for detachably coupling the first end of the conveyor with the first end of the support arm such that the conveyor hopper is position below the main hopper discharge. When the conveyor is uncoupled from the first end of the support arm, the conveyor can rotate to a loading position wherein the discharge thereof can be positioned over the main hopper.

Claims

1. A seed or grain tender comprising:

a frame;

a main hopper mounted on said frame and having a main hopper discharge;

a base mounted on said frame below said main hopper discharge;

a support arm having first and second ends;

a first coupling connecting said first end of said support arm with said base, said first coupling being rotatable in relation to said base about a first vertical axis of rotation, and said first end of said support arm being rotatable in relation to said first coupling about a first horizontal axis of rotation;

a conveyor having a longitudinal axis and first and second ends, a conveyor hopper at said first end, a conveyor discharge at said second end, and an internal elevator for moving seed or grain from said conveyor hopper to said conveyor discharge; and

a second coupling connecting said second end of said support arm with said conveyor at an approximate center of gravity of said conveyor, said second coupling defining a second vertical axis of rotation that is not parallel to said conveyor longitudinal axis, and said conveyor being rotatable in relation to said second end of said support arm about said second vertical axis of rotation between an unloading position wherein said conveyor hopper is disposed below said main hopper discharge to receive agricultural product from said main hopper and a loading position wherein said conveyor discharge is disposed above said main hopper to dispense agricultural product into said main hopper.

2. The seed or grain tender of claim 1, wherein said support arm extends upwardly at an acute angle from said base.

3. The seed or grain tender of claim 2, wherein said conveyor is parallel to said support arm in said unloading position.

4. The seed or grain tender of claim 3, wherein said conveyor is disposed above said support arm in said unloading position.

5. The seed or grain tender of claim 1, wherein said conveyor is rotatable in relation to said second coupling about a second horizontal axis of rotation.

6. The seed or grain tender of claim 5, wherein said second horizontal axis of rotation extends through said second coupling.

7. The seed or grain tender of claim 1, further comprising a stand coupled with said first end of said conveyor and movable between a stowed position allowing said conveyor hopper to be positioned below said main hopper discharge when said conveyor is in said unloading position and an extended position supporting said conveyor hopper above the ground when said conveyor is in said loading position.

8. The seed or grain tender of claim 1, wherein said first vertical axis extends through said first end of said support arm.

9. The seed or grain tender of claim 1, wherein said first vertical axis extends through said base.

10. The seed or grain tender of claim 1, wherein said second end of said support arm terminates at or near said approximate center of gravity of said conveyor.

11. The seed or grain tender of claim 1, wherein said first end of said support arm is fixed at a first height and said second end of said support arm is pivotable between a range of heights.

12. The seed or grain tender of claim 1, further comprising a lift device for adjusting a height of said second end of said support arm.

13. The seed or grain tender of claim 12, wherein said lift device is a pressurized cylinder.

14. The seed or grain tender of claim 12, wherein said lift device is a hydraulic cylinder.

15. The seed or grain tender of claim 1, wherein said first coupling is a U-shaped member with a horizontal base portion and a pair of upright portions, and wherein said first horizontal axis extends through said upright portions of said first coupling.

16. The seed or grain tender of claim 1, further comprising a locking mechanism for locking or unlocking said support arm in relation to said base.

17. The seed or grain tender of claim 16, wherein said locking mechanism includes a pin releasably engageable with one of a plurality of holes formed in said base.

18. The seed or grain tender of claim 17, wherein said pin is spring-biased toward said holes in said base.

19. The seed or grain tender of claim 17, wherein said internal elevator includes a motor-driven belt.

20. A seed or grain tender comprising:

a frame;

a main hopper mounted on said frame and having a main hopper discharge;

a base mounted on said frame below said main hopper discharge;

a support arm having first and second ends;

a first coupling connecting said first end of said support arm with said base, said first coupling being rotatable in relation to said base about a first vertical axis of rotation, and said first end of said support arm being rotatable in relation to said first coupling about a first horizontal axis of rotation;

a lift device extending from said base to a portion of said support arm between said first and second ends such that said support arm extends upwardly at an acute angle from said base;

a conveyor having a longitudinal axis and first and second ends, a conveyor hopper at said first end, a conveyor discharge at said second end, and a motor-driven elevator for moving seed or grain from said conveyor hopper to said conveyor discharge; and

a second coupling connecting said second end of said support arm with said conveyor at an approximate center of gravity of said conveyor, said second coupling defining a second vertical axis of rotation that is not parallel to said conveyor longitudinal axis, and said conveyor being rotatable in relation to said second end of said support arm about said second vertical axis of rotation between an unloading position wherein said conveyor hopper is disposed below said main hopper discharge to receive agricultural product from said main hopper and a loading position wherein said conveyor discharge is disposed above said main hopper to dispense agricultural product into said main hopper, wherein said conveyor is disposed parallel to and above said support arm in said unloading position; and

a locking mechanism for locking and unlocking said support arm in relation to said base.

21. The seed or grain tender of claim 20, wherein said conveyor is disposed above said support arm in said unloading position.

22. The seed or grain tender of claim 20, wherein said conveyor is rotatable in relation to said second coupling about a second horizontal axis of rotation.
