本考案は、エンジン冷却ラジエータ及びこのラ
ジエータに対する冷却フアンをエンジンの前方に
配置した農用トラクターの原動部構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure of a driving unit of an agricultural tractor in which an engine cooling radiator and a cooling fan for the radiator are disposed in front of the engine.
上記農用トラクターにおいて、従来、バツテリ

置するようにしており、次の如き不利が在つた。
In the above-mentioned agricultural tractors, conventionally, when storing the battery in the engine bonnet, the battery was placed in front of the engine cooling radiator and furthermore, as shown in Japanese Utility Model Application Publication No. 58-40476, In order to keep the height of the front end of the engine bonnet as low as possible so that visibility from the control section to the front of the aircraft can be seen as close to the front end of the aircraft as possible, the front end of the engine bonnet is positioned below the top of the engine cooling radiator. There were some disadvantages.

That is, although the battery is located almost entirely in front of the radiator, the air that is supplied to the radiator by the cooling fan or the air that is discharged from the radiator by the cooling fan is notwithstanding this. In order for the wind to flow smoothly, it was necessary to secure a wide air passage between the battery and the radiator, which meant that the distance between the battery and the radiator became large, which increased the length of the aircraft.
このように機体長さ（エンジンボンネツトの長
さ）が大になると、特に前方下方の見通しが悪く
なるので、本考案はバツテリーをエンジンボンネ
ツト内に収容する場合に、ラジエータの冷却風が
スムーズに流れるようにしながら、前方下方の見
通しを良くすることを目的としている。 As the length of the fuselage (length of the engine bonnet) increases, visibility especially towards the front and downward becomes poor, so this invention is designed to ensure that the radiator's cooling air flows smoothly when the battery is housed within the engine bonnet. The purpose is to improve the visibility forward and downward while allowing the vehicle to flow smoothly.

The feature of the present invention is that the structure of the driving part of the agricultural tractor as described above is configured as follows. In other words, the battery is placed between the radiator and the engine, with the lower end located above the rotation axis of the cooling fan, and with the lower part wrapped around the top of the engine when viewed from the front and rear of the aircraft. An upper bonnet part that covers the upper half and battery is provided, and an exhaust port is provided in the front part of the radiator and cooling fan in the lower bonnet part below this upper bonnet part, and cooling air is discharged from the exhaust port to the front and outside. The cooling fan is rotated to
例えば第１図に示すように、バツテリー１３を
ラジエータ１１とエンジン９の間に配置すること
によつて、ラジエータ１１の前側にバツテリー１
３を配置する従来構造よりも、エンジンボンネツ
トの長さを短くできる。
For example, as shown in FIG. 1, by arranging the battery 13 between the radiator 11 and the engine 9, the battery
The length of the engine bonnet can be made shorter than the conventional structure in which the engine bonnet 3 is arranged.
冷却フアン１２の回転軸芯Ｐの上方にバツテリ
ー１３を配置することによつて、バツテリー１３
の下側に冷却風用の風路１６が広く確保できる。
そして、下部ボンネツト部分８ａに排気口１７を
設けているので、この排気口１７が前述の風路１
６と略同じ高さの位置にくる。 By arranging the battery 13 above the rotation axis P of the cooling fan 12, the battery 13
A wide air passage 16 for cooling air can be secured below.
Since the exhaust port 17 is provided in the lower bonnet portion 8a, this exhaust port 17 connects to the air passage 1 described above.
It will be at approximately the same height as 6.
これにより、冷却フアン１２による冷却風は、
前述の風路１６からラジエータ１１を通り、排気
口１７から略一直線に前外側に排出される。 As a result, the cooling air from the cooling fan 12 is
The air passes through the radiator 11 from the air passage 16 mentioned above and is discharged from the exhaust port 17 in a substantially straight line to the front and outside.
又、バツテリー１３の下部とエンジン９の上部
をラツプさせることにより、バツテリー１３及び
これを覆う上部ボンネツト部分８ｂの高さを低く
抑えることができる。 Furthermore, by making the lower part of the battery 13 and the upper part of the engine 9 overlap, the height of the battery 13 and the upper bonnet portion 8b that covers it can be kept low.
以上のようにバツテリーを配置することによ

トラクターの操縦性を向上させることができた。
By arranging the battery as described above, it was possible to reduce the length of the engine bonnet while keeping the height of the engine bonnet low. This improves the forward and downward visibility for the operator and improves the maneuverability of the agricultural tractor.
又、冷却風がバツテリーの下側の広い風路を略
一直線に流れるように構成できたので、ラジエー
タによる熱交換が効率良く行われるようになる。 Furthermore, since the cooling air can be configured to flow in a substantially straight line through a wide air passage below the battery, heat exchange by the radiator can be performed efficiently.

As shown in FIG. 3, it has a pair of left and right steering type front wheels 1, 1 and rear wheels 2, 2, and
A lift arm 5 that connects various working devices such as a rotary tiller so that it can be raised and lowered, and a power take-off shaft 6 that transmits power to the connected working device are installed at the rear of the self-propelled body which has a control section 4 at the rear. , which constitutes a riding type agricultural tractor.

連結してある。 As shown in FIG. 1, the driving unit 3 is composed of a lower bonnet part 8a fixed to the fuselage frame 7, and an upper bonnet part 8b that can be opened and closed by swinging up and down about the axis on the front end side. Inside the engine bonnet 8, a cleaner 10 for engine hot combustion air is provided above the engine 9, an engine cooling radiator 11 and a cooling fan 12 for the radiator 11 are provided in front of the engine 9, and a battery 13 is provided with a lower end thereof. It is located above the rotation axis P of the cooling fan 12, and is arranged between the engine 9 and the radiator 11 in such a manner that the lower part and the upper part of the engine 9 overlap when viewed in the longitudinal direction of the aircraft. It is connected to the body frame 7 via a battery mounting base 15 through which a transmission rotating shaft 14 to the cooling fan 12 passes.

It is introduced from the air passage 16 below 3 and between the rear part of the battery mounting base 15 and sent to the front side of the aircraft,
It is configured so that it passes through the radiator 11 and is discharged from the exhaust port 17 to the front and outside of the engine bonnet 8, so that the inside air of the bonnet heated by the heat dissipation of the engine itself, the hot air for cooling the radiator, and the noise of the driving part are removed. It is designed to flow out to the front side of the aircraft so that it is difficult to flow into or be transmitted to the control section 4.
