Unloading conveyor of granular material from a truck or trailer to a grain bagging machine

An unloading conveyor system for transferring granular material from a vehicle to a grain bagging machine, the unloading conveyor system configured to convey granular material, such as grain, pellets, or dry sand, from a discharge downspout of a vehicle, including a truck, trailer, or grain cart, to a mechanically driven conveying system for grain bagging machines of the type that fill agricultural silo bags, the unloading conveyor system comprising:

• a receiving trough configured to be positioned proximate to a ground surface and beneath the discharge downspout of the vehicle, the receiving trough including a plurality of sweep augers configured to collect the granular material;
• a conveying auger comprising a first tubular section, a second tubular section, and a third tubular section arranged in series, wherein the first tubular section is coupled at a first end to the receiving trough to receive the granular material therefrom, the first tubular section is pivotally connected at a second end opposite the first end to a first end of the second tubular section via a first horizontal articulation axis disposed at topmost portions of the first tubular section and the second tubular section, enabling relative rotation in a vertical plane, the second tubular section is pivotally connected at a second end opposite the first end to a first end of the third tubular section via a second horizontal articulation axis disposed at lowermost portions of the second tubular section and the third tubular section, enabling relative rotation in the vertical plane, the third tubular section is pivotally connected at a second end opposite the first end to a rotatable hopper via a third horizontal articulation axis extending through the third tubular section and walls of the rotatable hopper, enabling rotation of the third tubular section in the vertical plane, the rotatable hopper is mounted on a turntable configured to rotate in a horizontal plane, and when the first tubular section, the second tubular section, and the third tubular section are deployed, the conveying auger forms a continuous path for the granular material from the receiving trough to the rotatable hopper;
• and
• a compression auger including a mouthpiece configured to receive the granular material, the compression auger disposed transversely relative to the conveying auger, wherein the mouthpiece is positioned beneath the rotatable hopper and connected thereto by a direct passageway configured to permit throughput of the granular material from the rotatable hopper to the compression auger.
