Abstract

A process and system are provided for preparing seed mixes having a target quantity and a target ratio of different types of seeds. The process generally includes portioning quantities of different types of seeds from bulk supplies of the seeds, and combining the portioned quantities of seeds to prepare the seed mixes. The system generally includes first and second dispensing assemblies for portioning the quantities of the different types of seeds from the bulk supplies, and a mixing assembly for receiving the portioned quantities of seeds as the seed mixes. The combined quantities of the different types of seeds in the seed mixes are substantially equal to the target quantity, and a ratio of the quantities of the different types of seeds is substantially equal to the target ratio.

First claim

What is claimed is:

1. A system for use in combining different types of seeds into a seed package, in a target quantity and a target ratio, the system comprising:
a seed packaging assembly operable to combine first and second types of seed into a seed package;
a first dispensing assembly disposed above the seed packaging assembly and configured to deliver a predetermined portion of the first type of seed to the seed packaging assembly for inclusion in the seed package;
a conveyor coupled to the first dispensing assembly and configured to transport the first type of seed, from a bulk supply of the first type of seed, to the first dispensing assembly;
a second dispensing assembly configured to deliver a predetermined portion of the second type of seed to the seed packaging assembly for inclusion in the seed package; and
a return coupled to the second dispensing assembly and operable to selectively transport the predetermined portion of the second type of seed from the second dispensing assembly to a storage bin, whereby the predetermined portion of the second type of seed is received in the storage bin instead of at the seed packaging assembly and is maintained separate from the first type of seed;
whereby, based on inclusion of the predefined portions of the first and second types of seed in the seed package, the seed package includes the target quantity and the target ratio of the first and second types of seed.

2. The system of claim 1 , further comprising at least one chute configured to receive the first type of seed from the first dispensing assembly and the second type of seed from the second dispensing assembly, together, in the at least one chute.

3. The system of claim 2 , wherein the at least one chute includes a door moveable between a closed position to retain the first and second types of seed in the at least one chute and an open position to release the first and second types of seed from the at least one chute, together, to the seed packaging assembly.

4. The system of claim 2 , wherein the at least one chute defines a bottom surface, the guide spaced apart from the bottom surface such that the first and second types of seed, when received in the at least one chute, intermix generally below the guide.

5. The system of claim 1 , further comprising the seed package having the target quantity of the first and second type of seed and the target ratio of the first type of seed to the second type of seed.

6. The system of claim 1 , further comprising a seed mixing assembly disposed above the seed packaging assembly and between the first dispensing assembly and the seed packaging assembly, the seed mixing assembly configured to receive the predetermined portion of the first type of seed from the first dispensing assembly and the predetermined portion of the second type of seed from the second dispensing assembly and deliver a mixture of the first and second types of seed to the seed packaging assembly for inclusion in the seed package.

7. The system of claim 6 , wherein the seed mixing assembly includes a container configured to receive the first type of seed from the first dispensing assembly and the second type of seed from the second dispensing assembly, the container including a guide disposed therein for directing the first type of seed and/or the second type of seed into the container.

8. The system of claim 7 , wherein the container defines a bottom surface, and wherein the guide is spaced apart from the bottom surface.

9. The system of claim 8 , wherein the bottom surface of the container includes a door moveable between a closed position for retaining the first and second types of seed in the container and an open position for releasing the mixture of the first and second types of seed from the container to the seed packaging assembly.

10. The system of claim 9 , wherein the seed mixing assembly further includes:
a main chute for delivering the first type of seed to the container at a first location of the container; and
a secondary chute for delivering the first type of seed to the container at a second location of the container separated from the first location of the container by the guide.

11. The system of claim 10 , wherein the seed mixing assembly further includes a chute for delivering the second type of seed to the container at the second location of the container.

12. The system of claim 1 , wherein the conveyor is a first conveyor; and
further comprising a second conveyor coupled to the second dispensing assembly and configured to transport the second type of seed, from a bulk supply of the second type of seed, to the second dispensing assembly.

13. The system of claim 12 , wherein the second dispensing assembly is disposed above the seed packaging assembly.

14. The system of claim 13 , wherein the second dispensing assembly includes:
a bin configured to initially retain the second type of seed in the second dispensing assembly when received from the second conveyor;
a vibratory feeder disposed below the bin and configured to receive the second type of seed from the bin;
a weighing plate disposed below the vibratory feeder, and configured to receive the second type of seed from the vibratory feeder and to measure a weight of the received seed; and
at least one hopper disposed below the weighing plate, the weighing plate configured to transfer the second type of seed to the at least one hopper, as the predetermined portion of the second type of seed, when the weight measured by the weighing plate satisfies a predetermined weight.

15. The system of claim 1 , wherein the second dispensing assembly includes at least one hopper configured to hold the predetermined portion of the second type of seed in the second dispensing assembly; and
wherein the return is coupled to the at least one hopper.

16. The system of claim 15 , further comprising a seed mixing assembly disposed above the seed packaging assembly; and
wherein the seed mixing assembly includes a chute for receiving the predetermined portion of the second type of seed from the second dispensing assembly, the return coupled to the at least one hopper of the second dispensing assembly at a location between the at least one hopper and the chute of the seed mixing assembly.

17. The system of claim 1 , wherein the second dispensing assembly includes:
a first surge bin configured to generate the predetermined portion of the second type of seed;
a first transport coupled to the first surge bin and configured to deliver the second type of seed to the first surge bin from a bulk supply of the second type of seed;
a second surge bin;
a second transport coupled to the first surge bin and to the second surge bin, the second transport configured to receive the predetermined portion of the second type of seed from the first surge bin and deliver the predetermined portion of the second type of seed to the second surge bin; and
a delivery unit disposed below the second surge bin and coupled thereto, the delivery unit configured to transport the predetermined portion of the second type of seed from the second surge bin to the seed packaging assembly for inclusion in the seed package.

18. The system of claim 17 , wherein the second dispensing assembly further includes a return coupled to the second surge bin and operable to selectively transport the predetermined portion of the second type of seed from the second surge bin to a storage bin, whereby the predetermined portion of the second type of seed is received in the storage bin instead of at the seed packaging assembly.
