  Further, by providing the wind direction plate 52 in this way, the selected wind from the auxiliary blower 32 that flows along the upper surface of the wind direction plate 52 generates a negative pressure on the lower side (rear side) of the wind direction plate 52 and causes vortices. It is possible to wind. Such a vortex may cause a reduction in the amount of air in the direction of blowing up between the fins 41 a, 41 a... Of the chaff sheave 41 among the selected air from the auxiliary air blower 32. Therefore, in this configuration, an opening 53 is formed between the wind direction plate 52 and the start end portion of the flow-down plate 39.

  Specifically, the opening on the front side of the space surrounded by the lower surface of the wind direction plate 52, the inner surfaces of the left and right side plates 54 and 54, and the upper surface of the flow-down plate 39 is the opening 53. The space communicates with a space formed between the chaff sheave 41 and the flow-down plate 39 in the swing sorting device 31. In other words, the sorting wind from the Kara 33 and the outside air (wind) due to the advance of the aircraft flow in from the opening 53, and these flow along the lower surface of the wind direction plate 52, and the chaff sheave 41 and the flow-down plate 39. And the wind from the auxiliary blower 32 that flows along the upper surface of the wind direction plate 52 is merged.

  Accordingly, it is possible to prevent a negative pressure (vortex) from being generated on the lower side of the wind direction plate 52, and therefore, between the fins 41a, 41a,... Of the chaff sheave 41 in the selected wind from the auxiliary blower 32. Reduction of the air volume in the blowing direction can be prevented, and the sorting performance can be further improved.
