COMBINE HARVESTER
Document Type and Number:
Japanese Patent JP2019080544
Kind Code:
A
Abstract:
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: A first 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 second purification device (14) for purifying nitrogen oxides is installed in parallel between the first 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 second purification device (14) faces a rear side of the cooling fan (42). When a surface temperature of the second purification device (14) reaches a first threshold temperature (T1) or more, a rotation speed of the cooling fan (42) is increased.SELECTED DRAWING: Figure 10
