PROBLEM TO BE SOLVED : To provide a working vehicle in which a sorting structure is simplified and downsized to ensure high sorting accuracy, accelerate the single graining of un-single-grained grains, and stabilize the vehicle body by lowering the gravity center of a grain tank. SOLUTION : The working vehicle has a threshing apparatus 6 for applying a threshing treatment to reaped grain culms, and a sorting apparatus 7 for applying a sorting treatment to a treated product obtained by the threshing treatment, wherein a cyclone sorting apparatus 7 for sorting the grains from the treated product with a whirlwind is provided as the sorting apparatus 7. A re-threshing apparatus for again applying a threshing treatment to a treated product is disposed in the threshing apparatus 6. The cyclone sorting apparatus 7 comprises a plurality of sorting portions 68, 69, and has a fan for forming a whirlwind which swivels and blows from one end of the sorting portions 68, 69 to the other end through the insides of the sorting portions 68, 69. The grain tank 8 for storing the grains obtained by the sorting treatment is disposed on the lower side of the vehicle body. COPYRIGHT : (C)2009, JPO&INPIT
