To provide a combine harvester that can restrain an excessive temperature increase of a purification device for exhaust gas and improve purification efficiency of the purification device.SOLUTION: An exhaust purification device (12) for purifying impurities in exhaust gas discharged from an engine is installed between a threshing device (4) and a grain tank (7) in a left-right direction. A urea purification device (14) for purifying nitrogen oxides is installed in parallel between the exhaust purification device (12) and the grain tank (7). A cooling fan (42) for cooling a condenser comprised in an air conditioning device provided in a steering part (5) is provided in a rear wall of a cabin (40) covering the steering part (5). The urea purification device (14) faces a rear side of the cooling fan (42). An air blowing guide (46) for vertically adjusting an air blowing direction of air discharged from the cooling fan (42) is provided.SELECTED DRAWING: Figure 10
【課題】排気ガスの浄化装置の過剰な温度上昇を抑制し、浄化装置の浄化効率を向上させることができるコンバインを提供する。【解決手段】脱穀装置(4)とグレンタンク(7)の左右方向での間に、エンジンから排出される排気ガス中の不純物を浄化する排気浄化装置(12)を設置し、この排気浄化装置(12)とグレンタンク(7)の間に窒素酸化物を浄化する尿素浄化装置(14)を並設し、操縦部(5)を覆うキャビン(40)の後壁に、操縦部(5)に設けられた空調装置に備えるコンデンサを冷却する冷却ファン(42)を設け、尿素浄化装置(14)を冷却ファン(42)の後側に臨ませ、該冷却ファン(42)から排風された空気の送風方向を上下に調整する送風ガイド(46)を設けた。【選択図】図10
