Abstract
An agricultural seeding machine includes a metering system and a damper arrangement. The metering system for the seeding machine includes selectively powered metering sections operable to individually allow or restrict seed dispensation. The damper arrangement is included 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 particulate metering section of said plurality of particulate metering sections being operably positioned between said tank and a respective particulate-transporting line of said particulate-transporting lines so as to control dispensation of the particulate from said tank to said respective particulate-transporting line;
- an airflow generator in communication with said particulate-transporting lines so as to generate respective pneumatic-conveying airstreams within said particulate-transporting lines;
- and
- a plurality of damper assemblies, each of which is positioned along a respective particulate-transporting line of said particulate-transporting lines downstream relative to said metering system and selectively located at least in part within the respective airstream to restrict airflow within said respective particulate-transporting line responsive to variations in metering of particulate to said respective particulate-transporting line.
