Abstract

A seed filling system is mounted to a trailing implement that is towed by an agricultural machine. The seed filling system has a reduced-volume receptacle for receiving seed and a metering assembly that causes the distribution of the seed through a manifold to respective storage containers of plural row units before the seed is dispensed to soil.

First claim

The invention claimed is:

1. A seed filling system mounted to a trailing implement configured to be towed by an agricultural machine, the seed filling system comprising:
a receptacle configured to receive seed from a source external to the trailing implement;
a manifold in fluid communication with the receptacle and configured to receive the seed;
a plurality of row units in fluid communication with the manifold, each row unit comprising a storage container and a seed dispensing assembly, wherein a total seed storage capacity of the storage containers is greater than a storage capacity of the receptacle; and
a metering assembly configured to cause a distribution of the seed from the manifold to each of the storage containers prior to the seed dispensing assembly dispensing the seed.

2. The seed filling system of claim 1 , further comprising at least one additional receptacle in fluid communication with the manifold.

3. The seed filling system of claim 1 , wherein the metering assembly comprises at least one hydraulic motor and at least one blower.

4. The seed filling system of claim 3 , wherein the metering assembly is configured to cause the distribution of the seed until a predetermined volume of each of the storage containers is filled with seed.

5. The seed filling system of claim 4 , wherein each of the storage containers comprises a vent, wherein the predetermined volume is a volume at which air flow through the vent is stopped, preventing ingress of further seed.

6. The seed filling system of claim 4 , further comprising a controller and at least one sensor wherein the at least one sensor is configured to provide an indication of a volume filled with seed compared to the predetermined volume and, based on the indication, the controller is configured to cause the metering assembly to turn off or disengage.

7. The seed filling system of claim 4 , further comprising a controller configured to cause the seed dispensing assembly to dispense the seed after the predetermined volume of each of the storage containers is filled with seed.

8. The seed filling system of claim 1 , further comprising a controller configured to cause the metering assembly to commence seed distribution operations.

9. The seed filling system of claim 8 , further comprising at least one sensor, wherein the controller is configured to cause the metering assembly to commence seed distribution operations based on the at least one sensor detecting a presence of the seed within or proximal to the receptacle.

10. The seed filling system of claim 8 , further comprising at least one sensor and a seed tender, wherein the controller is configured to cause the metering assembly to commence seed distribution operations based on the at least one sensor detecting a presence of the seed tender proximal to the receptacle.

11. The seed filling system of claim 8 , further comprising a user interface, wherein the controller is configured to cause the metering assembly to commence seed distribution operations responsive to receiving an input at the user interface.

12. A seed filling method for a trailing implement towed by an agricultural machine, the method comprising:
receiving seed in at least one receptacle from a source external to the trailing implement; and
while receiving the seed, distributing the seed to respective storage containers of a plurality of row units before dispensing the seed to soil from the row units, wherein a total seed storage capacity of the storage containers is greater than a storage capacity of the at least one receptacle.

13. The seed filling method of claim 12 , wherein distributing the seed to respective storage containers comprises driving at least one blower with at least one hydraulic motor to cause air flow to the respective storage containers.

14. The seed filling method of claim 13 , further comprising terminating the distributing when a predetermined volume of each of the storage containers is filled with seed.

15. The seed filling method of claim 14 , wherein air flow through a vent of each of the storage containers ceases when the predetermined volume is filled with seed.

16. The seed filling method of claim 14 , further comprising detecting, using at least one sensor, when the predetermined volume is filled with seed.

17. The seed filling method of claim 14 , further comprising dispensing the seed to the soil from the plurality of row units after the predetermined volume of each of the storage containers is filled with seed.

18. The seed filling method of claim 12 , further comprising commencing distribution of the seed based on detecting a presence of the seed within or proximal to the at least one receptacle or based on detecting a presence of a seed tender proximal to the at least one receptacle.

19. The seed filling method of claim 12 , further comprising commencing distribution of the seed based on receiving input at a user interface.
