した座席部８よりなる。 1 is a driver's seat in a traveling work machine such as a combine harvester equipped with an appropriate traveling device A, and its configuration is as follows:
An engine 5 is provided on one side of working devices such as a reaping part B and a threshing part C placed on a machine stand 1a, and is equipped with an operating part 3 in the front and a blower fan 4 in the rear via a standing wall 2.
It consists of a seat part 8 in which a seat 7 is installed on an engine cover 6 with an interior.

９は変速レバー等各種操作レバー１０を支架し

もに、下部をデツキ部１１に突出ピン１３を差込
んで、デツキ部１１上の側方を覆うとともに着脱
自在に取付けられている。 The vertical wall 2 is made of a wide plate-like body, and its upper part is fastened to the horizontal support frame 9 with screws 12, and its lower part is inserted into the deck part 11 with a protruding pin 13, and the lower part is connected to the deck part 11. It covers the sides and is detachably attached.

やかな機外への放出を促進させるものである。 Reference numeral 25 designates a guide piece formed by bending the end of the air outlet 23 of the shielding plate 21 toward the air exhaust direction.
Further, the exhaust air Y is appropriately directed in the exhaust direction to promote prompt discharge to the outside of the aircraft.

そして、上述のように構成した運転席はコンバ
インに限られることなく、広く一般の走行作業機
の運転席に用いられる。 The driver's seat configured as described above is not limited to combine harvesters, but is widely used as the driver's seat of general traveling working machines.

〔作用・効果〕[Action/Effect]

従つて、本考案構成の運転席を備えたコンバイ

し、機体外方に放出される。 Therefore, when the engine 5 is started and work is performed on a combine harvester equipped with the driver's seat configured according to the present invention, cooling air is sucked in from the intake hole 81 as the blower fan 4 rotates, and passes through the radiator 82 to the engine 5. While being cooled, the air is discharged from an air exhaust port 61 formed on the inside of the engine cover 6, passes through the transport device B1 and transmission case B2 of the adjacent reaping section B, and is discharged to the outside of the machine.

この時、機体の前方で前記立壁２の側部に停滞

３の直前を勢い良く通過する排風により、吸入口
２２から空気が吸い込まれることにより、共に吸
い込まれて通風路２４を通り、前記ラジエーター
８２を冷却した排風Ｙとともに機外に放出され
る。 At this time, the heated air
Air is sucked in from the suction port 22 by the exhaust air passing just in front of the radiator 3, passing through the ventilation passage 24 and being discharged outside the machine together with the exhaust air Y that has cooled the radiator 82.

以上に説明してきたように、本考案では立壁付
近に停滞しようとする加温空気は機体前方の外気
とともに、立壁及び遮板で構成される通風路内

出されるので、この部での加温空気の停滞は抑制
されるとともに、立壁そのものも通風路を介して
冷されるので、異常に加熱されることがない。 As explained above, in this invention, the warmed air that tends to stagnate near the vertical wall is sucked into the ventilation path consisting of the vertical wall and shielding board by the engine exhaust, along with the outside air in front of the aircraft. Since it is discharged to the outside, stagnation of heated air in this area is suppressed, and the vertical wall itself is also cooled through the ventilation passage, so it will not be heated abnormally.

また、通風路を介して設けられる遮板が停滞す
る加温空気の熱を直接立壁に伝えることもない。 Moreover, the heat of the stagnant heated air is not directly transmitted to the standing wall by the shielding plate provided through the ventilation path.

それ故、運転者の足が上記立壁に触れても何ら
運転には支障なく、快適な運転作業ができる効果
を生ずるものである。 Therefore, even if the driver's feet touch the vertical wall, there is no problem in driving, and the effect is that the driver can drive comfortably.

また、このような加熱防止装置は遮板を立壁に
対設すると言う、簡潔で廉価な構成で行なうこと
ができる特徴があり、両者を一体的に構成した場
合には枠剛性が向上し防振効果を伴い、運転席の
居住性を一層高めることができる。 In addition, this type of heating prevention device has the feature that it can be implemented with a simple and inexpensive configuration in which the shielding plate is installed opposite to the vertical wall, and when the two are configured integrally, the frame rigidity improves and vibration isolation is achieved. With this effect, the comfort of the driver's seat can be further improved.
