Abstract
An agricultural air cart assembly includes an agricultural air cart. The agricultural air cart includes independently controllable, first and second product metering systems that regulate the rates at which product flows from a storage compartment into corresponding first and second distribution lines. Independently controllable, rotatable fans are operatively connected to corresponding first and second distribution lines and are configured to generate optimized air flows in the first and second distribution lines which entrain and carry the product downstream toward corresponding row units at balanced pressures.
Claims8
An agricultural air cart assembly for transmitting a controlled volume of product from a storage compartment to a plurality of row units for depositing the product on an agricultural field, comprising:
- a first distribution line for receiving a first supply of the product from the storage compartment therein;
- a second distribution line for receiving a second supply of the product from the storage compartment therein;
- a rotatable first fan being operatively connected to the first distribution line and having an adjustable rotational speed, the rotatable first fan being configured such that rotation of the rotatable first fan generates an air flow in the first distribution line which entrains and carries the first supply of the product downstream toward a first row unit;
- and
- a rotatable second fan being operatively connected to the second distribution line and having an adjustable rotational speed, the rotatable second fan being configured such that rotation of the rotatable second fan generates an air flow in the second distribution line which entrains and carries the second supply of the product downstream toward a second row unit;
- a first meter wheel communicating with the storage compartment and being rotatable about an axis such that rotation of the first meter wheel transfers the first supply of the product from the storage compartment to the first distribution line;
- and
- a first motor assembly operatively connected to the rotatable first fan and the first meter wheel.

- a rotatable second fan being operatively connected to the second distribution line and having an adjustable rotational speed, the second fan being configured such that rotation of the second fan generates an air flow in the second distribution line which entrains and carries the second supply of the product downstream toward a second row unit;
- and
- a first meter wheel adapted for transferring the first supply of the product from the storage compartment to the first distribution line, the first meter wheel being adjustable to provide a selected rate at which the first supply of product is transferred to the first distribution line;
- wherein:
- the first meter wheel and the rotatable first fan are powered by a first motor;
- the first meter wheel is operatively connected to the first motor by adjustable linkage;
- and
- adjustment of the linkage varies the rate at which the first supply of product is transferred to the first distribution line.
