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,

at least one toolbar module detachably coupled to said frame for coupling said drive module to an agricultural implement or another modular toolbar module, and

multiple toolbar modules coupled to each other in series to form a modular toolbar, said toolbar modules carrying ground engaging implements, and which includes a cable extending through all the toolbar modules of said modular toolbar to hold said modules together while allowing the toolbar to flex to follow the contour of the ground engaged by said implements.

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 an 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 is which said ground-engaging elements are selected from the 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 toolbars 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 caring 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 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 with said elongated modular toolbar extending horizontally from said drive module for coupling said drive module to an agricultural implement or another modular toolbar 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, and

a driveshaft extending through the length of said toolbar and coupled to said drive motor, and a driven module attached to said modular toolbar and coupled to said driveshaft.
