A center drive portable auger system for transporting particulate material. The auger includes an auger tube having a feed end and a discharge end, an auger drive shaft within the auger tube, and an auger flighting mounted to the auger drive shaft for transporting particulate material from the feed end to the discharge end of the auger tube. A gear box is positioned adjacent an external surface of the auger tube between the discharge end and the feed end for center driving the auger flighting. Since the central gear is external to the auger tube it does not restrict the flow of the particulate material within the auger tube, does not leak oil into the particulate material, and runs cooler than the internal gear boxes due to less friction during operation. A drive linkage operates between the gear box and the auger drive shaft for driving the auger flighting.
An auger for transporting particulate material, the auger comprising:
In a center drive portable auger having an auger tube with a feed end and a discharge end and a substantially constant diameter, an auger drive shaft within the auger tube, an auger flighting mounted on the auger drive shaft for transporting particulate material from the feed end to the discharge end of the auger tube, and a center drive positioned between the feed end and the discharge end of the auger tube and operable with the auger drive shaft, the improvement being the center drive comprising a drive member mounted on the auger drive shaft and having a diameter less than the substantially constant diameter of the auger tube, an external gear box positioned outside of the auger tube and operable with the drive member such that oil in the gear box does not leak into particulate material in the auger tube, and a drive tube extending substantially perpendicularly into the auger drive tube and surrounding the drive member and linking the external gear box to the auger drive shaft such that the particulate material cannot contact the drive member, such that the gear box runs cooler than if the gear box was positioned inside the auger tube.
