| A series of semi-circular cut-out portions are provided on the underside of an auger tube which are covered with blanks when the cleaning device is not in use, but which are covered with semi-circular sieves when it is desired to clean grain or the like being augered. The mesh of the screens is selected to suit the cleaning desired. A shroud encloses the sieves and an auxiliary auger is situated at the base of the shroud and is driven by the main auger drive. This auxiliary or return auger moves wheat seeds and the like which have passed through the sieve, to a discharge at the lower end of the shroud regardless of the angle of inclination of the main auger assembly. Reinforcing means are provided on the upper side of the main auger tube (tension) and upon the lower side thereof (compression) in order that distortion and/or damage will occur to the main auger tube particularly during transportation of the auger assembly from one place to another. | ||||||
