Abstract
A metering system for a seeding machine is provided. The metering system includes selectively powered metering sections operable to individually allow or restrict seed dispensation. A damper arrangement is also provided so that pneumatic conveying of the particulate within the machine is consistently maintained when particulate flow is varied between the metering sections.
Claims9
An agricultural air cart comprising:
- a tank configured to contain particulate;
- a plurality of particulate-transporting lines;
- a metering system including a plurality of particulate metering sections,
- each of said metering sections being operably positioned between the tank and a respective one of the particulate-transporting lines so as to control dispensation of the particulate from the tank to the respective line;
- an airflow generator in communication with the particulate-transporting lines so as to generate respective pneumatic-conveying airstreams within the lines;
- and
- a plurality of damper assemblies, each of which is positioned along a respective one of the particulate-transporting lines downstream relative to the metering system and selectively located at least in part within the respective airstream to restrict airflow within the respective particulate-transporting line responsive to variations in metering of particulate to the respective particulate-transporting line.
