Method for measuring air efficiency and efficacy in a combine harvester |
摘要 |
The airflow through a harvesting machine is adjusted by calculating a G-factor at a first point on an upper chaffer to determine if it is greater than 1+n, where n represents a desired factor. A blower is adjusted to reduce an airstream if the G-factor is greater than 1+n. A MOG factor is calculated if the G-factor is less than 1+n. The blower is adjusted to increase the airstream if the MOG-factor is less than 1+x, where x represents a desired factor. A MOG-factor is calculated at a second point if the MOG-factor at the point is greater than 1+x and the blower is adjusted to reduce the airstream if the MOG-factor at the second point is greater than 1+y, where y represents a desired factor or adjusted to increase the airstream if the MOG-factor at the second point is less than 1+y. |

1. A method of managing the airflow of a blower mechanism through the threshing and cleaning systems of a combine harvesting machine, the method comprising:
calculating a G factor at a first point on an upper chaffer that is just underneath the forward edge of a grain pan to determine if the G factor at said first point is greater than 1+n, where n represents a desired factor; adjusting the blower mechanism to cause a reduction in the rearward movement of grain if the G factor at said point is greater than 1+n; calculating a MOG factor is calculated at said first point if the G factor calculated at said point is less than 1+n; adjusting the blower mechanism to increase the airstream so as to entrain more MOG if the MOG factor at said first point is less than 1+x, where x represents a desired factor; calculating a MOG factor at a second point if the MOG factor at said first point is greater than 1+x; adjusting the blower to reduce the airstream if it is determined the MOG factor at said second point is greater than 1+y, where y represents a desired factor; and adjusting the blower to increase the airstream if it is determined the MOG factor at said second point is less than 1+y. |
