Problems solved by technology

[0005] The combines described in Patent Documents 1 and 2 utilize steel pipes to connect the exhaust manifold of the engine and the purifying device for purifying unburned fuel and granulated substances. There is a problem that the purification device is damaged in advance due to the vibration of the engine
In addition, since the cleaning device is arranged between the side wall of the threshing device and the side wall of the grain tank, it is necessary to narrow the width of the grain tank in the left-right direction, and there is a problem that the storage capacity of the grain tank decreases.

Abstract

A combine harvester comprises a purification device excellent in durability and a grain tank capable of storing a great quantity of grains. A DPF (diesel particulate filter) unit (40) which is used for purifying exhaust of an engine (9) is disposed on a portion, in the bilateral center of a body, of a transverse side of a threshing device (5), and an exhaust manifold (30B) of the engine (9) is connected with a gas inlet (40E) of the DPF unit (40) through flexible connecting pipes (52 and 72). In addition, the DPF unit (40) is disposed between the threshing device (5) and the grain tank (6), the lower portion of the grain tank (6) is provided with an inclined wall (21D) inclined downward towards the outer side of the body, and the DPF unit (40) enters a space of the lower side of the inclined wall (21D).

Description

technical field [0001] The present invention relates to a combine equipped with a diesel particulate filter. Background technique [0002] Conventionally, the structure which arrange|positions the exhaust device which purifies unburned fuel and granular material contained in exhaust gas in the space formed between a threshing apparatus and a grain tank is proposed (refer patent document 1, 2). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2010-84542 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2010-209813 [0005] The combine harvesters described in Patent Documents 1 and 2 use steel pipes to connect the exhaust manifold of the engine and the purifying device for purifying unburned fuel and granulated substances. Therefore, there is a problem that the purifying device is damaged prematurely due to engine vibration. In addition, since the cleaning device is arranged between the side wall of the threshing device and the side wall of the grain tank, i...
