COMBINE

摘要

PROBLEM TO BE SOLVED: To lower the temperature of exhaust gas discharged from an exhaust gas cleaning device.SOLUTION: A combine includes: a grain tank (5) mounted on a machine body frame (1); a discharge device (8) for discharging grains accumulated in the grain tank (5) to the outside of the machine; a blower (32) for supplying compressed air for conveying grains to the discharge device (8); a DPF (51) for collecting a particulate material contained in exhaust gas discharged from an engine (E); an exhaust pipe (55) for discharging the exhaust gas purified by the DPF (51) to the outside of the machine; an exhaust gas dilution part (60) for mixing the exhaust gas discharged from the exhaust pipe (55) with ambient air and lowering the temperature of the exhaust gas; and a switch valve (70) that can be switched between a state in which the compressed air from the blower (32) is supplied to a discharge device (8) side and a state in which it is supplied to an exhaust gas dilution part (60) side.
