Embodiment Construction

[0052] Hereinafter, the first embodiment of the present invention will be described in detail with reference to the drawings. In addition, for ease of understanding, directions are shown for ease of description, but the structure is not limited to this.

[0053] Such as Figure 1 ~ Figure 4 As shown, the combine harvester 1 is equipped with: a traveling device 3 consisting of a pair of left and right crawlers walking in the farmland; a harvesting device 4 that harvests grain stalks from the farmland at the front end of the machine body; behind it, the grain stalks are threshed and screened The threshing device 5; and a grain container 6 for storing threshing and sieved grains arranged side by side on the right side of the threshing device 5. The front side of the grain container 6 faces the back of the harvesting device 4, and is provided for operation The driver’s cab 7.

[0054] In addition, the rear side of the grain container 6 is provided with a discharge auger 8 that dischar...

Abstract

The task of the invention is to improve the durability of a pipeline at an exhaust influx side of an exhaust purification device and is not apt to generate metal fatigue, and to enable high-temperature exhaust gas exhausted from an upper end part of an exhaust pipe is difficult to be toward rice crumbs accumulated at a lower part of a machine body. The solution of the invention is that an inclined wall (23B) which is inclined upwards toward a threshing device (5) is arranged at the bottom of a grain container (6), an exhaust purification device (40) which removesparticle-shaped substances from exhausts of an engine (9) is configured in a space under the inclined wall (23B), an influx port of the exhaust purification device (40) is connected to an exhaust manifold (30B) through a connecting pipe (50) having flexibility, an outflux port of the exhaust purification device (40) is connected to a lower end part of an exhaust pipe (61) which guides gas exhausted from the outflux port to outside the machine, and the exhaust pipe (61) is arranged in an upward extending manner along a winnow device (14).

Description

Technical field [0001] The invention relates to a combine harvester. Background technique [0002] In the past, it has been proposed that an exhaust purification device (Diesel particulate filter: diesel particulate filter, hereinafter referred to as "DPF") that purifies particulate matter contained in the exhaust gas of a diesel engine is arranged between the threshing device and the grain container. The structure of the space. [0003] As an example, Patent Document 1 discloses disposing a DPF under an inclined wall formed at the bottom of a grain container, connecting the lower end of an exhaust pipe to the outlet of the exhaust gas purification device, and aligning the exhaust pipe This is the technique of extending the valley upward device once. [0004] In addition, Patent Document 2 and Patent Document 3 disclose a technique of extending the upper end of such an exhaust pipe to a position higher than the upper surface of the threshing device. [0005] Prior art literature [0...
