Abstract

See full text

A meter apparatus for dispensing agricultural products into a product conduit carrying a product air stream at a product air pressure. A sealed tank is pressurized to a tank pressure that is substantially equal to the product air pressure, and a meter roller mounted on a shaft is mounted in a housing below the sealed tank. A drive is operative to rotate the shaft and the meter roller. Clearance spaces are provided each side of the meter roller. Bearings mount the shaft to the housing, and seals are mounted to the shaft and to the housing between the right and left bearings and the meter roller. The housing defines right and left chambers between the seals and the meter roller. The purging conduit carries a purging air stream at a purging air pressure that is greater than the product air pressure into the chambers, and through the clearance space.
