Grain flow regulator for a grain dryer

摘要

An apparatus for controlling grain flow within a column of a grain dryer is disclosed. The grain dryer includes a metering roll positioned to contact grain advancing out of a discharge opening of the column. The grain dryer further includes a regulator member which is movable between a flow regulating position and a trash escape position. The regulator member contacts either the metering roll, or grain supported by the metering roll when the regulator member is positioned in the flow regulating position. The regulator member is spaced from the metering roll by a distance sufficient to enable a trash object to advance between the regulator member and the metering roll when the regulator is positioned in the trash escape position. A method of controlling grain flow within a column of a grain dryer is also disclosed.
