<P>PROBLEM TO BE SOLVED: To make a combine harvester capable of avoiding the local temperature elevation of an exhaust pipe line while suppressing the generation of soil dust caused by exhaust, although installing an exhaust muffler at the upper part of an engine and exhausting engine exhaust gas in the rear lower direction of a traveling machine body. <P>SOLUTION: This combine harvester is provided by installing an exhaust pipe 43 guiding and exhausting the flow of exhaust gas from the exhaust muffler 41 toward the rear lower direction of the traveling machine body linearly by making it pass through between a threshing device and a grain recovery part from an exhaust port 42a of the exhaust muffler 41, and also including a guiding surface 44a having a crossing angle to the axial core 43d of the exhaust pipe 43 and arranging a flow guide 44 guiding the exhaust gas of the exhaust pipe 43 so as to flow toward the rear direction of the traveling machine body by the guiding surface 44a, at the lower side of the exhaust port 43a of the exhaust pipe 43. <P>COPYRIGHT: (C)2012,JPO&INPIT |
