Problems solved by technology

[0010] As in Patent Document 1 or 2, when the DPF case and the SCR case are assembled separately from the engine, there is a problem that the temperature of the exhaust gas supplied from the engine to the DPF case or the SCR case decreases, and the diesel fuel Chemical reactions such as regeneration of the particle filter and selective catalytic reduction tend to be incomplete, so a special device for keeping the temperature of the exhaust gas in the SCR box at a high temperature is required.

Embodiment Construction

[0040] Hereinafter, embodiments for actualizing the present invention will be described with reference to the drawings. refer to Figure 1 ~ Figure 3 , illustrating the overall structure of the general-purpose combine harvester. In addition, in the following description, the left side toward the advancing direction of the traveling body 1 is simply called the left side, and the right side toward the advancing direction is also simply called the right side. Such as Figure 1 ~ Figure 3 As shown, a traveling body 1 supported by a pair of left and right walking crawler belts 2 as a running part is provided. At the front part of the traveling body 1, the harvesting device 3 for harvesting and introducing grain stalks is attached so as to be able to be raised and lowered around the harvesting rotation fulcrum shaft 4a by a single-acting hydraulic cylinder 4 for lifting. On the traveling body 1, the threshing apparatus 5 which has the threshing drum 6, and the grain tank 7 which ...

Abstract

The present invention addresses the problem of providing a work-vehicle engine device capable of affixing a first case (62) and a second case (229) with a high level of rigidity, by using the frame (91) of an engine room (92). A work-vehicle engine device provided with a first case (62) for removing particulate matter in the exhaust gas of an engine (14), and a second case (229) for removing nitrogen oxide in the exhaust gas of the engine (14), wherein the first case (62) is provided, via a first-case support body (211), in the engine room (92) for housing the engine (14) in the interior thereof, and the second case (229) is provided in the engine room (92) via second-case support bodies (230, 231).

Description

technical field [0001] The present invention relates to an engine unit of a working vehicle such as a combine harvester that harvests grain stalks planted in a field and collects grains, or a forage combine harvester that harvests grain stalks for feed and collects them as feed. More specifically, It relates to an engine unit of a work vehicle equipped with an exhaust gas purification device for removing particulate matter (smoke, particulates) contained in exhaust gas of a diesel engine or the like or nitrogen oxide substances (NOx) contained in exhaust gas. Background technique [0002] Conventionally, in the exhaust path of a diesel engine, as an exhaust gas purification device (exhaust gas post-treatment device), the following technology is known: a housing with a diesel particulate filter (hereinafter referred to as a DPF housing) and a built-in The case of the urea selective reduction catalyst (hereinafter referred to as the SCR case) guides the exhaust gas into the DP...
