combine harvester

Abstract

The utility model provides a gas exhausting structure of an engine. A gas exhausting purification device (40) which removes particle-shaped materials of waste gas from the engine (9) is supported on a machine body frame (2), an inflowing opening of the gas exhausting purification device (40) is connected to a gas exhausting header pipe (30B) of the engine (9) through a connecting pipe (50) with flexibility, an outflowing opening of the gas exhausting purification device (40) is connected to the lower end portion of a gas exhausting pipe (61) which guides the waste gas exhausted from the outflowing opening to the exterior of a machine body, and the gas exhausting pipe (61) extends upwards. In addition, the engine (9) is supported on the machine body frame (2) through an elastic part (9a). According to the structure, metal fatigue of a pipeline on the gas exhausting inflowing side of the gas exhausting purification device is hard to generate, durability is improved, and the high-temperature waste gas exhausted from the upper end portion of the gas exhausting pipe is difficultly towards the lower portion of the machine body.

Description

technical field [0001] The present invention relates to combine harvesters. Background technique [0002] As a prior art, there is a structure in which a threshing device is provided on the left side of the body frame, a grain container is provided on the right side of the body frame, an engine is installed on the front side of the grain container, and an engine room containing the engine is installed. With air filter. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-22244 [0006] In the prior art described above, since the air filter is installed in a small space in the engine room, the size of the air filter is limited due to the restriction of the installation space, thereby reducing the air intake efficiency, and there is a possibility that the performance of the engine cannot be fully exerted. question.

Problems solved by technology

[0006] In the prior art described above, since the air filter is installed in a small space in the engine room, the size of the air filter is limited due to the restriction of the installation space, thereby reducing the air intake efficiency, and there is a possibility that the performance of the engine cannot be fully exerted. question

[0007] In addition, since the air filter is installed in the enclosed space of the engine room, there is also a problem that maintenance of the air filter cannot be easily performed.
