Abstract

A system and method for conveying agricultural material in a harvester. One harvester includes a rotor which rotates to separate a plant into a first agricultural material and a second agricultural material. A grate is disposed vertically below the rotor and further separates the first and second agricultural materials from one another. A first conveyor receives the first and second agricultural material directly from a trailing end of the rotor and a trailing end of the grate.

First claim

The invention claimed is:

1. A method for determining a total amount of agricultural material harvested by a harvester, comprising:
measuring with a first sensor connected to a first conveyer a first weight of the agricultural material while the agricultural material is conveyed by the first conveyor of the harvester during a first time period after the agricultural material has exited a rotating threshing system of the harvester;
measuring with a second sensor connected to a second conveyer a second weight of the agricultural material while the agricultural material is conveyed by the second conveyor during a second time period; the second conveyor positioned and configured to receive the agricultural material at least from a cleaning system comprising a sieve, the cleaning system positioned to receive crop material that has exited the threshing system; and
calculating with a control system connected to the first and second sensor the total amount of agricultural material harvested by the harvester based at least partially on the first weight and the second weight.

2. The method of claim 1 , wherein measuring the first weight of the agricultural material comprises measuring the first weight of the agricultural material while the harvester is harvesting the agricultural material.

3. The method of claim 1 , comprising measuring a third weight of the agricultural material while the agricultural material is conveyed by the second conveyor, downstream from the first conveyor, during the first time period, the second time, or a combination thereof.

4. The method of claim 3 , comprising determining the total amount of agricultural material harvested by the harvester based at least partially on the third weight.

5. The method of claim 1 , comprising determining a harvesting rate of the agricultural material based at least partially on the first weight, the second weight, the first time period, the second time period, or a combination thereof.

6. The method of claim 1 , wherein the control system comprises control circuitry and the control circuitry is operably connected to the first and second sensors and configured for determining the total amount of agricultural material harvested at least partially from the first weight and the second weight.

7. The method of claim 1 , wherein the rotating threshing system comprises a rotor configured to rotate to separate a plant into a first agricultural material and a second agricultural material;
a grate disposed vertically below the rotor and configured to further separate the first and second agricultural materials from one another; and
the first conveyor is configured to receive the first and second agricultural material directly from a trailing end of the rotor and a trailing end of the grate.

8. The method of claim 1 , wherein the first and second conveyers rearwardly convey the agricultural material.
