Abstract

An agricultural product delivery system and method is provided. The agricultural product delivery system includes a feeder for receiving particulate materials and a storage tank for holding particulate materials. A control system controls a filling system for providing particulate materials to the feeder. The control system is configured to communicate with a filling system to substantially maintain an alignment between the filling system and the feeder.

First claim

I claim:

1. An agricultural product delivery system comprising:
a feeder for receiving particulate materials;
a storage tank for holding particulate materials;
a rotary air lock coupled between the feeder and the storage tank, and being operable to transfer particulate materials from the feeder to the storage tank while substantially maintaining a pressure in the storage tank, the rotary air lock including a plurality of vanes providing pockets in between for holding particulate materials, wherein rotation of the rotary air lock rotates the pockets from the feeder to a sealed area and from the sealed area to the storage tank such that the particulate materials exit the pockets and fall into the storage tank;
sensing hardware in communication with the sealed area, the sensing hardware being configured to measure a volume of particulate material transferred from the feeder to the storage tank;
a metering box operatively connected to the storage tank and configured to transfer the particulate materials from the storage tank to a ground engaging tool; and
a control system for controlling a tilling system providing particulate materials to the feeder, wherein the control system is configured to communicate with the filling system to substantially maintain an alignment between the filling system and the feeder.

2. The delivery system of claim 1 , further comprising a global positioning system (GPS), wherein the control system uses the GPS to substantially maintain the alignment.

3. The delivery system of claim 1 , further comprising a wireless communication unit (WCU), wherein the control system wirelessly communicates with the filling system using the WCU.

4. The delivery system of claim 1 , wherein the delivery system is an air cart and the storage tank has a capacity over 500 bushels.

5. The delivery system of claim 1 , wherein the filling system comprises an auger conveyor.

6. The delivery system of claim 1 , wherein the control system controls at least one of a speed and a direction of travel for the filling system.

7. The delivery system of claim 1 , wherein the control system is operable to summon the filling system from a distal location and initiate control of the filling system when in a proximal location.

8. The delivery system of claim 1 , wherein the feeder comprises at least one of a hopper and a drogue.

9. A method for filling an agricultural product delivery system comprising:
(a) receiving particulate materials at a feeder from a separately operated filling system;
(b) interconnecting the feeder to a storage tank with a rotary air lock, the rotary air lock being operable to transfer particulate materials from the feeder to the storage tank while substantially maintaining a pressure in the storage tank;
(c) holding particulate materials in pockets between a plurality of vanes of the rotatry air lock;
(d) rotating the rotary air lock such that the pockets are moved from a loading position wherein the pockets are in communication with the feeder to a sealed area and from the sealed area to unloading position wherein the pockets are in communication with the storage tank such that the particulate materials exit the pockets and fall into the storage tank;
(e)using a sensing hardware, sensing a volume of particulate material passing through the sealed area from the feeder to the storage tank;
(f) holding particulate materials in a storage tank;
(g) transferring the particulate materials from the storage tank to a ground engaging tool with a metering box operatively connected to the storage tank; and
(h) communicating with and electronically controlling the filling system providing particulate materials to the feeder to substantially maintain an alignment between the filling system and the feeder.

10. The method of claim 9 , further comprising using a GPS to substantially maintain the alignment.

11. The method of claim 9 , further comprising wirelessly communicating with the filling system using a WCU.

12. The method of claim 9 , further comprising controlling at least one of a speed and a direction of travel for the filling system.

13. The method of claim 9 , further comprising summoning the filling system from a distal location and initiating control of the filling system when in a proximal location.

14. The method of claim 9 , further comprising detaching a tank from the filling system and receiving particulate materials at the feeder from the tank.

15. The method of claim 9 , further comprising controlling a general transfer rate of the particulate materials to a ground engaging tool.

16. An agricultural product delivery system comprising:
a filling system comprising an auger conveyor for providing particulate materials;
a feeder for receiving particulate materials from the filling system;
a storage tank for holding particulate materials;
a rotary air lock coupled between the feeder and the storage tank, and being is operable to transfer particulate materials from the feeder to the storage tank while substantially maintaining a pressure in the storage tank, the rotary air lock including a plurality of vanes providing pockets in between for holding particulate materials, wherein rotation of the rotary air lock rotates the pockets from the feeder to a sealed area and from the sealed area to the storage tank such that the particulate materials exit the pockets and fall into the storage tank;
sensing hardware in communication with the sealed area, the sensing hardware being configured to measure a volume of particulate material transferred from the feeder to the storage tank;
a metering box operatively connected to the storage tank and configured to transfer the particulate materials from the storage tank to a ground engaging tool; and
a control system for controlling the filling system providing the particulate materials to the feeder, wherein the control system is configured to communicate with the filling system to substantially maintain an alignment between the filling system and the feeder.
