PROBLEM TO BE SOLVED: To prevent grain bites in an extension auger for discharging grains during interruption of discharging, to enlarge an extension stroke, and to improve efficiency of grain discharging operation. SOLUTION: The reaping thresher supports an extension cylinder (15) that concentrically extends from a slide support portion (14) arranged slidably along a horizontal transporting auger cylinder (13) and is concentric with an extension auger shaft (16) and turnable is formed with an outlet (17) at the transporting end part of vertical one side of the extension cylinder (15), an expansion portion (24) expanding in a direction of separating from the axis of the extension auger shaft (16) in a prescribed region in the axial direction of the extension auger shaft (16) at the other vertical side of the extension auger (15) and a semicylindrical inner cover (25) that shields a space between the expansion portion (24) and each divided helix (27) when the expansion portion (24) is turned to an upper side by the turning of the extension cylinder (15).
