And the same code | symbol as the said embodiment is attached | subjected to each same member. This embodiment is effective when the length of the poultry house 51 is longer than, for example, 100 m.

  FIG. 13 (schematic front view) shows a third embodiment of the present invention. In this embodiment, the auxiliary oil temper 25 for connecting the auxiliary wire 24 is not provided so as to cover the entire side outside air inflow portion 4 but is directed from the exhaust portion 6 toward the outside air inflow portions 2a and 2b. It was installed up to the middle of 4. In this case, the opening / closing of the baffle 9 by the auxiliary drive unit 26 is not performed in a portion other than the portion where the auxiliary oil temper 25 is installed, and the portion where this is not installed can only be opened / closed by the main drive unit 21.

FIG. 14 (schematic front view) shows a fourth embodiment of the present invention. In this embodiment, the distance setting from each tip of the auxiliary wire 24 to each stopper 23 is changed, the descending distance of the support wire 10 is changed, and the degree of openness of the side outside air inflow portion 4 is set on one of the wife surfaces. The outside air inflow portions 2a and 2b are small, gradually increasing toward the middle, and slightly smaller on the exhaust portion 6 side on the other end face side. When the outside air temperature is particularly low, such as during the severe winter season, the outside air inflow portions 2a and 2b on one side of the wife are closed and the rotation of the fan 5 is controlled by the controller 30 so that the air flow inside the poultry house 1 flows. Becomes extremely slow or stops, and the force to draw the outside air flowing in from the side outside air inflow portion 4 to the poultry house central side is weakened. When this pulling-in force is weakened, a phenomenon occurs in which the outside air once flows into the exhaust section 6 and flows out again from the side outside air inflow section 4 on the exhaust section 6 side without reaching the center in the width direction of the poultry house 1. Since the temperature in the center in the width direction of the poultry house 1 is increased, the degree of openness of the side outside air inflow parts 2a and 2b on the exhaust part 6 side is slightly reduced to prevent the outside air from flowing out again. The distance from the tip of the auxiliary wire 24 at a predetermined portion to the stopper 23 is set so as to reach the center in the direction.

  The present invention is not limited to the above embodiments. For example, the displacement body 17 of the elevating mechanism 11 is not provided with the winding pulley 16, and the tip of the auxiliary wire 24 is provided in a portion where the winding pulley 16 is provided. May be fixed directly. Further, the side outside air inflow portion 4 may be provided only on one side, not on both sides. Furthermore, the stopper 23 of the auxiliary wire 24 may be movable, and the position setting of the stopper 23 may be changed after installation instead of being set in advance as in the above embodiment.
