摘要：
A tailings conveyance including a housing having a front plate, a back plate, and a wall, and is adapted to recycle tailings through a cleaning system of a combine using at least one impeller. The wall of the housing describes an arc near the impeller paddles over a segment of a circle described by the circumference of the impeller. The wall further continues on a tangent away from the circle at a point of tangency. A sensor is positioned proximate to the point of tangency, and senses whether a space between the front plate and the back plate directly adjacent to the sensor is obscured by tailings as the impeller rotates. A controller or control system connected to the sensor calculates an amount or percentage of time the space between the front plate and the back plate directly adjacent to the sensor is obscured by tailings as the impeller rotates.
