Abstract

A modular autonomous agricultural vehicle includes a drive module having a frame, a ground-engaging element rotatably coupled to the frame, a power source, and a drive motor receiving power from the power source and coupled to the ground-engaging element for rotating the ground engaging element. At least one toolbar module is detachably coupled to the frame for coupling the drive module to an agricultural implement or another modular toolbar segment. The modular toolbar preferably includes multiple toolbar modules coupled to each other in series to form the modular toolbar.

Claims

1. A modular autonomous agricultural vehicle comprising

at least one drive module having a frame, a rotatable ground-engaging element coupled to said frame, a power source, and a drive motor receiving power from said power source and coupled to said ground-engaging element for rotating said element, and

multiple toolbar modules coupled to each other in series to form an elongated modular toolbar having a selected length, at least one of said toolbar modules detachably coupled to said frame of said drive module,

said elongated modular toolbar extending horizontally from said drive module along the length of the elongated modular toolbar for coupling said drive module to an agricultural implement or another modular toolbar module,

wherein each of said multiple toolbar modules is a separate element from said at least one drive module,

wherein said ground-engaging element is mounted on said frame for movement around a vertical axis for controlling the direction of movement of both the drive module and the elongated modular toolbar,

a driveshaft extending through the length of said elongated modular toolbar and coupled to said drive motor, and

a driven module attached to said modular toolbar and coupled to said driveshaft.

2. The modular autonomous agricultural vehicle of claim 1 in which each of said toolbar modules has the same width as one of the rows in the agricultural field to be planted.

3. The modular autonomous agricultural vehicle of claim 1 in which said drive module includes at least two of said ground-engaging elements.

4. The modular autonomous agricultural vehicle of claim 3 in which said ground-engaging elements are selected from a group consisting of wheels and articulated tracks.

5. The modular autonomous agricultural vehicle of claim 3 in which said ground-engaging elements are mounted for movement between an operating position in which the ground-engaging elements are positioned for traversing an agricultural field, and a retracted position in which the ground-engaging elements are positioned to make the vehicle more compact for stowage or transporting.

6. The modular autonomous agricultural vehicle of claim 1 in which adjacent toolbar modules are coupled to each other to permit pivoting movement of said adjacent modules relative to each other.

7. The modular autonomous agricultural vehicle of claim 6 in which said coupling of adjacent toolbar modules limits the degree of pivoting movement of those modules relative to each other.

8. The modular autonomous agricultural vehicle of claim 1 in which said toolbar modules include hoppers for carrying commodities.

9. The modular autonomous agricultural vehicle of claim 1 in which said toolbar modules include support brackets adapted to be secured to hoppers for carrying commodities.

10. The modular autonomous agricultural vehicle of claim 1 in which said ground-engaging element is pivotably coupled to said frame of said drive module.

11. The modular autonomous agricultural vehicle of claim 1 in which said drive module includes an attachment plate for coupling said drive module to said modular toolbar.

12. A modular autonomous agricultural vehicle comprising

at least one drive module having a frame, a rotatable ground-engaging element coupled to the frame, and a drive motor coupled to the ground-engaging element for rotating the ground-engaging element;

multiple toolbar modules coupled to each other in series to form an elongated modular toolbar having a selected length, at least one of the toolbar modules detachably coupled to the frame of the drive module; and

a driveshaft coupled to the frame of the drive module, the driveshaft extending through the length of the elongated modular toolbar, wherein;

the ground-engaging element is mounted on the frame for movement around a vertical axis for controlling the direction of movement of both the drive module and the elongated modular toolbar, and

the frame of the drive module does not move relative to the driveshaft.

13. The modular autonomous agricultural vehicle of claim 12, wherein the ground-engaging element is mounted for movement between an operating position in which the ground-engaging element is positioned for traversing an agricultural field, and a retracted position in which the ground-engaging element is positioned to make the vehicle more compact for stowage or transporting.

14. The modular autonomous agricultural vehicle of claim 12, wherein the at least one drive module includes a first drive module attached to a first end of the elongated modular toolbar, and a second drive module attached to a second end of the elongated modular toolbar.
