。[Detailed Description of the Invention] [Field of Industrial Application] The present invention has an engine mounted on the rear side inside the engine bonnet at the front of the fuselage, a radiator for cooling the engine disposed on the front side, and a radiator for cooling the engine. The present invention relates to a driving unit structure of an agricultural tractor, which is equipped with a cooling fan immediately behind the bonnet and is configured to suck cooling air from the front of the bonnet.

528号公報に開示してあるように、前記冷却ファンと

た。In the above structure, conventionally, for example,
As disclosed in Japanese Patent No. 528, the cooling fan and the engine were placed close to each other, and the cooling exhaust air outlet was formed on the rear side of the engine bonnet.

その熱気が運転者に降りかかったり、排風による風切り
騒音が大きくなる等の問題もあった。However, in the above conventional structure, since the engine is located immediately behind the cooling fan that generates backward cooling air, the smooth flow of cooling air is obstructed by the engine, and the amount of air that should be efficiently taken in from the front grille is reduced. This has the drawback that the cooling efficiency of the radiator is reduced due to the limited amount of air flow, and the cooling exhaust air is discharged from the outlet near the operating section.
There were also problems such as the hot air falling on the driver and the wind noise caused by the exhaust air becoming louder.
本発明は、合理的な配置構造により、上記したような不
都合点を解消することを目的としている。The present invention aims to eliminate the above-mentioned disadvantages through a rational arrangement structure.
本発明の特徴は、冒記構成の農用トラクタの原動部構造

されるよう構成してある点にあり、その作用・効果は次
の通りである。A feature of the present invention is that in the structure of the driving part of an agricultural tractor having the above configuration, the cooling fan and the engine are arranged with a large space between them, and the side surface of the bonnet between the cooling fan and the engine is arranged. A cooling air outlet is formed, and the cooling exhaust air is discharged to the outside of the machine only from the outlet, and its functions and effects are as follows.
つまり、冷却ファンの後方側には前記空間を形成してあ
るので、生起される冷却風は流動を阻害されることなく
円滑に機内に吸入される。That is, since the space is formed on the rear side of the cooling fan, the generated cooling air is smoothly drawn into the machine without its flow being hindered.
その結果、冷却風の風量が増大しエンジン部側空間の換
気の効率も良くなり、ラジェータの冷却効率も増大する
。しかも、冷却排風はエンジンよりも機体前方側に位置
する排出口からエンジン部空間の掃気を行った後に排出
される。As a result, the volume of cooling air increases, the efficiency of ventilation of the engine side space improves, and the cooling efficiency of the radiator also increases. Furthermore, the cooling exhaust air is discharged from the exhaust port located on the front side of the aircraft body rather than the engine after scavenging the engine space.

きくなるといった不都合を回避できるようになった。Therefore, according to the present invention, by rationally improving the arrangement structure of various devices in the driving part, the cooling efficiency of the radiator and the scavenging efficiency of the space above the engine are improved.
In addition to improving engine cooling performance,
Since the heated exhaust air is discharged outside the machine from a location away from the driving section, it is now possible to avoid inconveniences such as hot air hitting the driver and increased wind noise.
