前記従来技術は、穀稈刈取作業時に穀物ヘッダで発生する粉塵が運転席の作業者に飛散し易い不具合があると共に、収穫作業途中で圃場枕地に到達し、次工程位置に方向転換するとき、刈取部を上昇させて持上げることにより、吸排塵ファンが高位置に支持されて高所に排塵が放出される不具合がある等の作業上の問題がある。 The conventional technology has a problem that dust generated in the grain header during the harvesting operation tends to be scattered to the operator in the driver's seat, and reaches the field headland during the harvesting operation and turns to the next process position. When the mowing unit is lifted and lifted, there is a problem in work such as a problem that the dust suction / discharge fan is supported at a high position and dust is discharged at a high place.

そこで、本発明では、運転台（１１）の側方に配置したフィーダハウス（１８）内の粉塵を、吸排塵ファン（２６）により防塵フード（２５）を通して外部へ排出するようにしたコンバインの刈取装置において、防塵フード（２５）は、上記吸排塵ファン（２６）を内設する上面フード（２３）と、同上面フード（２３）と連通する側面フード（２４）とを具備し、上面フード（２３）は、フィーダハウス（１８）の上面に開設した吸塵口（２８）を介してフィーダハウス（１８）内と連通させると共に、側面フード（２４）は、フィーダハウス（１８）の一側面でかつ運転台（１１）に設けた運転席（１２）の作業者側と反対の側面に配置し、フィーダハウス（１８）内の粉塵を吸排塵ファン（２６）により吸引して、上面フード（２３）と側面フード（２４）とを通してフィーダハウス（１８）の一側下方に排出させるようにしたことを特徴とするコンバインの刈取装置を提供するものである。Therefore, in the present invention, the harvesting of the combine in which the dust in the feeder house (18) arranged on the side of the cab (11) is discharged to the outside through the dust-proof hood (25) by the suction / discharge dust fan (26). In the apparatus, the dust-proof hood (25) includes an upper surface hood (23) in which the suction / exhaust dust fan (26) is provided, and a side hood (24) communicating with the upper surface hood (23). 23) communicates with the inside of the feeder house (18) through a dust suction port (28) opened on the upper surface of the feeder house (18), and the side hood (24) is one side surface of the feeder house (18) and It is arranged on the side opposite to the operator side of the driver's seat (12) provided in the cab (11), and the dust in the feeder house (18) is sucked by the suction / discharge dust fan (26), and the top hood (23) There is provided a combine of cutting device, characterized in that the through the side hood (24) so as to be discharged on one side below the feeder house (18).

本発明では、運転台（１１）の側方に配置したフィーダハウス（１８）内の粉塵を、吸排塵ファン（２６）により防塵フード（２５）を通して外部へ排出するようにしたコンバインの刈取装置において、防塵フード（２５）は、上記吸排塵ファン（２６）を内設する上面フード（２３）と、同上面フード（２３）と連通する側面フード（２４）とを具備し、上面フード（２３）は、フィーダハウス（１８）の上面に開設した吸塵口（２８）を介してフィーダハウス（１８）内と連通させると共に、側面フード（２４）は、フィーダハウス（１８）の一側面でかつ運転台（１１）に設けた運転席（１２）の作業者側と反対の側面に配置し、フィーダハウス（１８）内の粉塵を吸排塵ファン（２６）により吸引して、上面フード（２３）と側面フード（２４）とを通してフィーダハウス（１８）の一側下方に排出させるようにした。したがって、穀物ヘッダ（１７）で発生する粉塵が運転席（１２）の作業者方向に飛散するのを防ぐと共に、フィーダハウス（１８）から脱穀部（４）に搬入される粉塵量を低減させることができる。In the present invention, in the combine harvester, the dust in the feeder house (18) disposed on the side of the cab (11) is discharged to the outside through the dust hood (25) by the dust suction fan (26). The dust-proof hood (25) includes a top hood (23) in which the suction / discharge dust fan (26) is provided, and a side hood (24) communicating with the top hood (23).
