Abstract:
In a grain wagon pivotally connected to a tow tractor for transferring grain from a field to an open-top semi-trailer, said wagon including a wheel supported frame having a hitch pivotally connecting said frame to said tractor, a container supported by said frame for receiving a volume of grain, an elongated auger conveyor including a motor driven auger with a helical flight within a tubular auger housing and having a lower portion and an upper portion, said lower portion of said auger conveyor mounted on said wagon and positioned to receive grain from said container, said upper portion of said auger conveyor supported for folding movement between a retracted stored position adjacent said container and an operating position projecting upwardly and laterally outwardly from said container, and said tubular housing for said upper portion of said auger conveyor having a discharge spout defining a discharge outlet, the improvement comprising a spout assembly including a tubular flow control spout supported by said discharge spout for tilting movement on a generally horizontal axis between an upper position and a lower position relative to said upper portion of said auger conveyor, a hydraulic actuator connected to tilt said flow control spout between said upper and lower positions, a hydraulic fluid supply line extending from said actuator along said auger conveyor and said frame and forwardly across said hitch to said tractor, said hydraulic fluid supply line being flexible to provide for pivoting said upper portion of said auger conveyor between said stored and operating positions and for pivoting said grain wagon relative to said tractor, and a hydraulic control valve on said tractor to enable the driver to control the tilting of said flow control spout while pulling said grain wagon along one side of the semi-trailer with said tractor for efficiently and uniformly filling and topping off the semi-trailer with grain.
