Air velocity indicator and control device
First Claim
1. An air seeder for distributing agricultural product, comprising:
- a pneumatic distribution system having a control device;
said control device having a body and an indicator assembly mounted at least partially with said body;
said body having an inlet;
an inlet transition segment, a tubular deflector housing defining an inner void space having multiple sidewalls, an outlet transition segment and an outlet; and
an indicator assembly mounted on said tubular deflector housing including a deflector plate assembly and a gauge assembly operably coupled to the pneumatic distribution system;
said gauge assembly operably coupled to said pneumatic distribution assembly;
said deflector plate assembly includes a deflectable plate mounted transversely within the void space of the tubular housing;
wherein a volume of flowing air and entrained agricultural product flows through the tubular housing and actuates the plate, the gauge assembly displaying a magnitude of plate deflection.

Abstract
An air velocity indicator and control device is provided for use with pneumatic distribution systems used in air seeders that pneumatically discharge agricultural product to the ground, seedbed, or furrow. The air velocity indicator and control device includes a tubular housing, extending between an inlet and an outlet, and pivotally housing a deflectable plate that actuates in response to encountering an airflow entrained with agricultural product. A magnitude of deflection of the deflectable plate, corresponding to airflow velocity, can be displayed through an indicator assembly. This enables a user to identify velocity variances and differentials within the air seeder and make corrective adjustments. In some implementations, multiple air velocity indicator and control devices are ganged together with deflectable plates that pivot in unison with each other. The relative angle of fixation of the deflectable plates, upon the pivot pin, can be adjusted to permit airflow tuning as needed.
