PROBLEM TO BE SOLVED: To effectively remove dust whirled up on the front side of a drivers seat during reaping operation in a general-purpose combine harvester, to facilitate driving operation of an operator, and to raise the efficiency in the reaping operation.SOLUTION: In the general-purpose combine harvester, a suction fan (7) for sucking the dust in a feeder case (5) is installed on an outer lateral face of the feeder case (5), and a dust suction port (6) is provided in a surface on the side of the drivers seat (3) of the feeder case (5). In addition, a part of the suction fan (7) is protruded upwardly from the top surface of the feeder case (5), and a second dust suction port (8) opening to the side of the drivers seat (3) is installed in a duct (24) covering the suction fan (7). Furthermore, a thirled iron plate or a wire net preventing the passage of grains is provided in the dust suction port (6), and the suction fan (7) is driven with an electric motor (9). An opening and closing port (10) for charging grain culms is installed in a site on the side of the suction fan (7) of the feeder case (5).COPYRIGHT: (C)2012,JPO&INPIT【課題】汎用コンバインでの収穫作業中に操縦席の前側で巻き上がる塵埃を効果的に除去して、作業者の運転操作を容易化し、刈取作業の能率を高める。【解決手段】汎用コンバインにおいて、フィーダーケース(5)の外側面に該フィーダーケース(5)内の塵埃を吸引する吸引ファン(7)を設けると共に、フィーダーケース(5)の操縦席(3)側の面に吸塵口(6)を設ける。また、吸引ファン(7)の一部をフィーダーケース(5)の上面から上方へ突出させ、吸引ファン(7)を覆うダクト(24)に操縦席(3)側に向けて開口する第二吸塵口(8)を設ける。また、吸塵口(6)に穀粒の通過を阻む目抜き鉄板或いは金網を設ける。また、吸引ファン(7)を電動モータ(9)で駆動する。また、フィーダーケース(5)の吸引ファン(7)側の部位に穀稈投入用の開閉口(10)を設ける。【選択図】図3
