Description

Harvester {HARVESTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester, and more particularly, to an exhaust gas post-treatment apparatus for reducing pollutants generated by the operation of an engine, The present invention relates to a harvesting machine capable of minimizing a change in the structure of an existing harvester and minimizing an increase in production cost of the harvester by arranging the harvester in parallel with a traveling path along the inside of the processing apparatus.

The harvester is an agricultural machine that runs on the farmland and takes the rice, barley, wheat, grass seeds, etc., as well as the threshing and sorting work. These harvesters are used to sort rice, barley wheat, and other crops, and then thresh, and sort and select.

Because these harvesters require strong traction due to the nature of their operations, diesel engines powered by diesel are being adopted. However, as already known, diesel engines have a problem in that a large amount of harmful gas and pollutants are discharged as compared with engines used for other fuels. Therefore, in an attempt to regulate the exhaust gas due to environmental problems, It is actively proceeding.

For example, to meet Tier 4 level environmental regulations in countries such as Europe and North America, the fuel injection timing of the diesel engine is delayed, the concentration of nitrogen oxides is reduced by using an exhaust gas recirculation device, Development of an engine that improves the combustion performance in order to reduce the material, and development of an exhaust gas aftertreatment apparatus for lowering the pollution degree of the exhaust gas.

However, since the harvester has various apparatuses such as a harvesting apparatus (cutting apparatus), a threshing apparatus, a grain tank and the like compared with other agricultural working vehicles such as a tractor and the like, the structure is considerably complicated, There is a space limitation in installing the device. Therefore, conventionally, an exhaust gas post-treatment apparatus is provided above the threshing apparatus or below the traveling gas.

However, when the exhaust gas aftertreatment device is disposed above the threshing device or under the traveling gas, there is a concern that the supporting structure for supporting the exhaust gas aftertreatment device becomes complicated and is not easy to maintain from the viewpoint of maintenance have. Therefore, it is required to efficiently arrange the post-treatment apparatus considering the maintenance property while effectively utilizing the limited space of the harvester.

In addition, the diesel particulate filter (DPF) adopted for the exhaust gas purification treatment is required to maintain a constant high-temperature environment because PM to be treated is treated by high-temperature combustion.

However, in the configuration in which the exhaust gas post-treatment device is disposed above the threshing device or below the traveling gas as described above, it is difficult to maintain the temperature of the exhaust gas post-treatment device at a high temperature, There is a problem that it can not be exercised effectively.

Further, in some cases, the post-treatment device may be installed on the upper part of the engine. However, when the post-treatment device is installed on the upper part of the engine, the position of the driver's seat provided on the upper part of the engine is increased, However, there is a problem that it is difficult to apply to the conventional harvesting machine because the electric field design corresponding thereto must be accompanied.

In addition, when the post-processing apparatus is installed on the upper portion of the engine, heat generated in the post-processing apparatus is transferred to the driver's seat, so that it is difficult to provide a heat insulating means between the driver's seat and the post-processing apparatus.
