Grain metering system for a grain dryer having improved grain flow angle configuration at grain column discharge opening

摘要

A grain dryer which includes a grain column through which grain may flow is disclosed. The grain column has a discharge opening. The grain dryer further includes a metering roll positioned to contact grain advancing out of the discharge opening of the grain column and a grain support member interposed between the metering roll and the discharge opening, the grain support member defining a substantially planar top surface. Rotation of the metering roll causes grain to advance out of the discharge opening, over the substantially planar top surface, and into contact with the metering roll. An angle THETA is defined between a line L1 defined by the substantially planar top surface and a horizontal line HL which intersects the line L1. The angle THETA is greater than or equal to 0 DEG , but less than or equal to 30 DEG .
