Problems solved by technology

In particular, when the combine harvester is running in wetlands, since a large amount of mud and the like adhere to the exhaust device, the amount of mud and the like that intrudes into the exhaust device also increases, so there is a problem that the running performance of the combine harvester is reduced.

Abstract

A combine has an exhaust device capable of efficiently discharging exhaust gas in a direction away from a machine body. The combine has a grain tank (17) for containing hulls after harvesting, threshing, and sorting processes, and also has the exhaust device (41) constructed from a silencer (42), a tail pipe (61), etc., with one end of the exhaust device connected to an engine (34) mounted on the machine body and the other end extended between a threshing section (15) and the grain tank (17). The tail pipe (61) connected to an exhaust manifold (36) of the engine (34) on the upstream side of the exhaust device (41) is supported by support members (82, 83) arranged on the threshing section (15).

Description

technical field [0001] The present invention relates to a combine harvester, and more specifically relates to the combine harvester technology in which an exhaust device is arranged on the upper part of the body. Background technique [0002] In the past, the exhaust device of the combine harvester is to pass through the lower part of the body from the engine and is arranged on the side of the body rear, and the exhaust gas produced by the engine is discharged at the body rear. The exhaust device includes an exhaust muffler for reducing exhaust sound, a tailpipe for exhausting exhaust gas, and the like (for example, refer to Patent Document 1). [0003] However, if exhaust devices such as exhaust mufflers and tailpipes are arranged at the lower part of the body, mud and the like rolled up during driving are likely to be caught on the exhaust devices. If mud or the like hangs on the exhaust device, the mud or the like may adhere to and solidify on the exhaust muffler and the...
