前記従来技術は、吸排塵ファン及び吸排塵フードの各下部をフィーダハウス内 部に突入させるから、フィーダハウスの上下幅を容易に縮少し得ず、フィーダハ ウス上面板と内部のコンベア上面との間に大きな空間が形成され、フィーダハウ スの吸排塵効率を容易に向上させ得ないと共に、左右方向の水平軸回りに吸排塵 ファンを回転させるから、吸排塵ファンの大径化及び回転低下などを容易に行い 得ず、吸排塵機能を維持し乍ら吸引圧力を容易に低下し得ず、稈または莢などを 吸引したり土砂粉塵の吸引力が不足する等の不具合があり、刈取り穀稈及び穀粒 などの吸込み防止並びに排塵能力の向上などを容易に図り得ない等の問題がある 。 In the prior art, since each lower part of the suction and exhaust fan and the suction and exhaust hood is inserted into the inside of the feeder house, the vertical width of the feeder house cannot be easily reduced, and the space between the upper surface plate of the feeder house and the upper surface of the internal conveyor is not obtained. A large space is formed in the feeder housing, making it difficult to improve the efficiency of suction and exhaust of the feeder house.In addition, since the intake and exhaust fan rotates around the horizontal axis in the horizontal direction, it is easy to increase the diameter of the intake and exhaust fan and reduce rotation. It is difficult to reduce the suction pressure while maintaining the suction and discharge function, and there are problems such as suction of culms or pods and insufficient suction power of sediment dust. There is a problem that it is not easy to prevent the suction of particles and the like and to improve the dust discharging ability.
【０００４】 また、吸排塵ファンを駆動する電動モータをフィーダハウス左右幅の外側に設 けるから、電動モータを衝突によって損傷させたり、電動モータ取付スペースの 確保によってフィーダハウスと運転台が離間する等の不具合がある。In addition, since the electric motor for driving the suction / discharge dust fan is provided outside the left and right widths of the feeder house, the electric motor may be damaged by collision, or the feeder house and the cab may be separated by securing an electric motor mounting space. There is a problem.

An electric motor (30) can be installed within the left and right widths of (18) to prevent damage due to collision of the electric motor (30) and to reduce the size of the aircraft by placing the feeder house (18) and the cab (11) close to each other. Driver's cab (11 Operator comfort improvement by increase in size of the one in which the it is possible to easily like.
