Grain mass flow sensor for an agricultural combine

摘要

A mass flow sensor for a combine is positioned in the transition housing between the paddle elevator of the clean grain elevator and the loading auger of the clean grain tank. The mass flow sensor comprises an impact plate having an arm which is axially aligned with the predominant grain flow from the paddle elevator. The arm is coupled to a force measuring assembly having a potentiometer for generating an electric signal that is proportional to impact force.
