Working vehicle including exhaust gas treatment device

摘要

A working vehicle includes an engine, a vehicle body frame on which the engine is mounted, an exhaust gas treatment device for treating exhaust gas of the engine, and a fixing base for fixing the exhaust gas treatment device, and the fixing base is separated from the engine by a gap. Furthermore, a support body for connecting the fixing base to the vehicle body frame is also separated from the engine by a gap. A bellows pipe for absorbing solid-borne sound is provided in an area where a suction pipe of the exhaust gas treatment device is connected to an exhaust manifold of the engine.

1. A working vehicle comprising:
an engine; a vehicle body frame on which the engine is mounted; an exhaust gas treatment device for treating exhaust gas of the engine; a fixing base for fixing the exhaust gas treatment device, the fixing base being separated from the engine by a gap; a support body for connecting the fixing base to the vehicle body frame, the support body being separated from the engine by a gap; and a bellows pipe for absorbing solid-borne sound, the bellows pipe being provided in a connection area where a suction pipe of the exhaust gas treatment device is connected to an exhaust manifold of the engine, wherein the suction pipe includes an upper pipe portion extending from a portion below a transverse cross-sectional center of the exhaust gas treatment device and being bent obliquely downward at an obtuse angle, and a lower pipe portion forming the connection area, and a depression angle of a pipe axis of the lower pipe portion relative to the exhaust gas treatment device is larger than that of the upper pipe portion.
