PRODUCT SENSORS FOR AIR SEEDER

摘要

The product meter of an air seeder is vertically positioned between a produc t tank and a primary air distribution manifold. The product meter is provided with an inlet passage and an outlet passage. Product from the product tank is received in the inle t passage where it is directed to the metering chamber. A meter roller is located in the metering chamber for metering the product received from the product tank. After the product has been metered it is transported though the outlet passage to the primary distribution manifol d. Optical product sensors may be located in either the inlet passage or the outlet passage to detect the operation of the product meter.
