  Next, the operation of the barn 1 will be described.

  When the entire opening 10 of the roof 7 of the barn body 2 is closed, as shown in FIG. 4, the inner lower curtain 21 and the outer lower curtain 23 are moved up to the upper limit position which is the fully closed position. . Even when the opening 10 is fully closed, the curtains 21 and 23, the nets 11 and 12, and the fixing plate 17 are transparent, so that sunlight can be taken into the barn body 2.

  When the entire opening 10 of the roof 7 of the barn body 2 is opened, as shown in FIG. 5, the inner lower curtain 21 and the outer lower curtain 23 are moved down to the lower limit position that is the fully open position. Let When the opening 10 is fully opened, the air in the barn body 2 can be ventilated.

  Here, for example, in winter in a cold region, as shown in FIG. 5, when the opening 10 is fully opened for ventilation, the heat in the barn body 2 escapes to the outside of the barn body 2, and the The temperature drops.

  Therefore, as shown in FIGS. 8 and 9, in order to prevent waste of heat energy, the stop positions of the inner lower curtain 21 and the outer lower curtain 23 are adjusted, and only a part of the opening 10 is opened. Let That is, for example, the opening amount of the opening 10 is adjusted according to the direction of the wind.

  As shown in FIG. 8, when the wind is blowing toward one side (upper and right side in FIG. 8), the opening amount of the opening 10 is set to a predetermined amount that is half or less.

  Then, moist air in the barn main body 2 (air with a humidity of a predetermined value or more) flows out of the barn main body 2 from the opening 10 through the nets of both nets 11 and 12. That is, since the vicinity of the outside of the opened portion of the opening 10 becomes negative pressure based on the wind force, the moist air in the barn main body 2 is pulled by the wind and efficiently flows out of the barn main body 2.

  At this time, the inner roll-down curtain 21 is in close contact with the surface of the inner net 11 opposite to the opening 10 and covers substantially the entire portion of the inner net 11 that faces the inner roll-down curtain 21. For this reason, it is suppressed that the crevice wind from the outside of the barn main body 2 flows into the barn main body 2 through the opening 10.

  Further, as shown in FIG. 9, when the wind is blowing toward the other side (upper left side in FIG. 9), the opening amount of the opening 10 is set to a minute predetermined amount smaller than that in FIG. To do.

  Then, also in this case, the moist air in the barn main body 2 (air whose humidity is a predetermined value or more) flows out of the barn main body 2 from the opening 10 through the nets of both nets 11 and 12. Note that due to the principle of the orifice, the flow rate of air from inside the barn body 2 is increased, and wind from outside the barn body 2 does not enter.

  At this time, the outer roll-down curtain 23 is in close contact with the surface of the outer net 12 opposite to the opening 10 and covers substantially the entire portion of the outer net 12 facing the outer roll-down curtain 23. For this reason, it is suppressed that the crevice wind from the outside of the barn main body 2 flows into the barn main body 2 through the opening 10.

  Thus, according to the barn 1, by adjusting the opening amount of the opening 10, the air in the barn main body 2 can be discharged out of the barn main body 2 from the opening 10, and the gap air is low in temperature. Can be prevented from flowing into the barn body 2 through the opening 10, so that damp air in the barn body 2 can be discharged out of the barn body 2 while suppressing the temperature drop in the barn body 2 in winter. Accordingly, the interior of the barn body 2 can be maintained in a comfortable environment for cattle and other livestock even in winter. For this reason, livestock can live without stress in the barn body 2, freezing in the barn 1, loss of livestock dying due to illness, etc. can be reduced, and the weight gain can be increased to improve both economically and food-wise.

  In addition, since the inner sway suppressing means 53 for suppressing the swaying of the inner lowering curtain 21 and the outer swaying suppressing means 54 for suppressing the swaying of the outer lowering curtain 23 are provided, the swinging of both the curtains 21 and 23 is appropriately suppressed. It is possible to effectively suppress the gap air from flowing into the barn body 2 through the opening 10.

  Furthermore, since the inner net 11, the outer net 12, the inner lower curtain 21, and the outer lower curtain 23 are all transparent, sunlight can be taken into the barn body 2 even when the opening 10 is closed. It is possible to further improve the environmental state in the barn body 2 and to facilitate the work in the barn body 2.

  In addition, the barn 1 is not limited to a cow barn, and may breed pigs, birds, and the like.

  Further, the inner and outer double curtains 21 and 23 are not limited to a configuration that moves up and down by the power from the drive unit of the drive operation means 31 and 51. Good.

  Furthermore, the curtains 21 and 23 and the nets 11 and 12 are not limited to one piece that is elongated in the horizontal direction, but may be divided into a plurality of pieces. That is, for example, the curtains 21 and 23 may be composed of a plurality of divided curtain members, and each divided curtain member may be individually movable up and down.

  Further, the transmittance of the transparent curtains 21 and 23, the nets 11 and 12, and the fixing plate 17 is preferably close to 100%, but the value is arbitrary, may be low, and may be colored. .

  Furthermore, for example, a configuration in which the sizes of the inner and outer curtains 21 and 23 are the same, a configuration in which the sizes of the inner and outer nets 11 and 12 are the same may be employed.

Further, the inner curtain that is provided inside the opening 10 (side inside the barn body) and opens and closes the opening 10 is the inner roll-down curtain 21, and is provided outside the opening 10 (side outside the barn body). The outer curtain that opens and closes the opening 10 is not limited to the configuration of the outer lower curtain 23. For example, although not shown, the inner curtain is the inner winding curtain and the outer curtain is the outer winding curtain, the inner A configuration in which the curtain is an inner roll-up curtain and the outer curtain is an outer roll-down curtain, a configuration in which the inner curtain is an inner roll-down curtain, and the outer curtain is an outer roll-up curtain may be used. That is, the curtain may be a lowering type that moves down by winding or a winding type that moves up by winding .
