Grain cart having an inclined folding unloading auger conveyor with an askewed flow control spout

摘要

A grain cart has a wheel supported container with an inclined auger unloading conveyor having an inclined lower section positioned to receive grain from the container and an upper section supported for folding movement between a stored position adjacent the container and an inclined discharge position projecting upwardly, forwardly and laterally outwardly from the left side wall of the container. The upper section of the auger conveyor has a tubular housing with an askewed discharge spout supporting a pivotable flow control spout for tilting movement on a horizontal axis extending parallel to the left side wall of the container for discharge of grain laterally across an open top rectangular semi-trailer within a vertical plane perpendicular to the left side wall of the cart. The flow control spout is tilted by a remotely controlled actuator for filling and topping off the semi-trailer including all four corner portions of the trailer.

主权项

1. In a grain cart adapted to be pivotally connected to a tow tractor for transferring grain from a field to an elongated rectangular open-top semi-trailer, said cart including
a frame supported for traversing the ground and having a hitch for pivotally connecting said frame to the tow tractor, a container supported by said frame for receiving a volume of grain and including a left side wall and a right side wall connected by a front wall and a rear wall, an elongated inclined auger unloading conveyor including a motor driven auger with a helical flight within a tubular auger housing, with said conveyor having an inclined lower section and an upper section, said lower section of said auger conveyor mounted on said container and positioned to receive grain from said container, said upper section of said auger conveyor supported for folding movement between a retracted stored position adjacent said container and an extended operating discharge position inclined upwardly and forwardly and laterally outwardly from a front corner portion of said container, the improvement wherein said housing of said upper section of said auger conveyor in said discharge position inclined upwardly and forwardly and laterally outwardly including a discharge spout projecting laterally at an askewed angle from said housing, said discharge spout supporting a flow control spout for tilting movement on a substantially horizontal axis askewed with respect to an axis of said auger within said upper section, with said horizontal axis extending substantially parallel to a side wall of said container, said control spout movable on said horizontal axis in a vertical plane spaced forwardly of said front wall of said container and perpendicular to said side wall of said container between a downwardly projecting first position and a laterally outwardly projecting second position, and a remotely controllable actuator connected to tilt said flow control spout between said first and second positions on said horizontal axis when said upper conveyor section is in said inclined discharge position for uniformly filling and topping off the semi-trader with grain including the filling of all four corner portions of the rectangular semi-trailer.
