Abstract
An exhaust gas processing device includes: an exhaust gas processing unit positioned above an engine; a reduction agent tank accommodating a reduction agent; a reduction agent supply unit attached to the exhaust gas processing unit; a cooling unit having a first end portion and a second end portion; a cooling water accommodation unit having a lower portion positioned below the cooling unit; a first pipe connecting the first end portion and the cooling water accommodation unit; a second pipe connecting the second end portion and the cooling water accommodation unit; a circulating device driven by the engine. The first pipe and the second pipe are connected to the lower portion. The first pipe includes: a connection portion connected to the first end portion; an apex portion positioned above the cooling unit; a supplying portion positioned between the connection portion and the apex portion. Thus, it is possible to suppress an increase in the temperature of the reduction agent supply unit.
