摘要:
An improved roller assembly for a metering device, with reduced contact between the surface of the roller and the inner surface of the metering housing so as to reduce the areas within the roller assembly where a blockage may occur, and an improved mounting of the metering device so as to improve access to the roller assembly for maintenance. Also provided is an improved process control for driving the stepper motor of a metering device, so as to better detect the onset of a stall condition of a stepper motor and temporarily increase the torque supplied to the motor to avoid a stall condition. Additionally, an improved air manifold incorporates venturi assemblies to reduce or eliminate blockages that may occur when a local reservoir for holding a small reserve of agricultural product adjacent the metering device has reached capacity due to continual supply of product from a product hopper.
