Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ventilation system for a livestock barn. That is, the invention relates to a ventilation system that exchanges the air inside the barn where livestock such as chickens and pigs are raised with the air outside the barn.

[Conventional technology]

Ventilation in livestock barns where livestock grow is carried out as follows. That is, an outside air intake fan is attached to a ventilation hole in a side wall of the attic of the livestock barn, and the outside air is taken into the attic by this outside air intake fan. And this outside air is
The air flows into the livestock growing room below through multiple ventilation holes in the ceiling. On the other hand, the livestock barn is provided with an exhaust passage for discharging the air in the room where the livestock grows, and at least a part of this exhaust passage is formed by the space between the side walls of the double wall structure that constitutes the room where the livestock grows. and has an opening in the inner side wall. The air in the room where the livestock grows is discharged to the outside through an opening in the inner side wall through a discharge passage.

[Problem that the invention seeks to solve]

Therefore, it is desirable to change the amount of ventilation depending on the season. For example, in the winter, reduce the amount of ventilation to prevent the temperature in the room where livestock grows, and conversely, increase the amount of ventilation in the summer. , prevent the temperature in the room where livestock grows from rising.

However, in the above-mentioned conventional ventilation system, since the opening area of the opening in the side wall for exhaust is constant, the amount of ventilation is constant, and there is a problem that detailed ventilation operations cannot be performed.

Furthermore, conventional livestock barns are equipped with an emergency door, and in the event of an accident, the emergency door is opened to allow livestock to evacuate outside. However, this requires a lot of effort and the effect is only temporary.

The present invention has been made in view of the above points. Furthermore, the purpose is to enable livestock to be easily evacuated from the barn in the event of an accident or the like.

c Means for Solving the Problems] The structure of the first invention for achieving the above object is that an outside air intake fan is attached to a ventilation hole in the side wall of the attic of the livestock barn, and the outside air intake fan allows air to flow inside the attic. The outside air taken in by the barn flows through the ventilation holes in the ceiling into the room where the livestock grow below, while the livestock barn is equipped with an exhaust passage to exhaust the air inside the room where the livestock grow. In a ventilation system for a livestock barn, in which at least a part of the discharge passage is constituted by a space between side walls of a double wall structure constituting a room in which livestock grow, and an opening is provided in the inner side wall, the opening in the inner side wall is provided. The structure of the second invention is characterized in that an outside air intake fan is attached to a ventilation hole in a side wall of the attic of the livestock barn, and the outside air intake fan Outside air is taken into the attic and flows into the room below where the livestock grow through a ventilation hole in the ceiling, while the livestock barn is equipped with an exhaust passage that exhausts the air inside the room where the livestock grow. In a ventilation system for a livestock barn, in which at least a part of the exhaust passage is formed in a space between side walls of a double wall structure constituting a room where livestock grow, and has an opening in the inner side wall,
An opening in the inner side wall is provided at the lower end, a rollable curtain is provided in the opening that can adjust the opening area, and an opening is provided in a portion of the outer side wall opposite to the opening in the inner side wall. , the frontage is covered with a curtain that can be rolled up.

[Effect]

The outside air taken into the attic by the outside air intake fan flows through the ventilation hole provided in the ceiling into the room below where the livestock grow. On the other hand, the air in the room where the livestock grows is exhausted through the exhaust passage from the opening in the inner side wall. At this time, depending on the season, etc., the roll-up curtain provided at the opening in the inner side wall is adjusted to vary the opening area of the opening to an appropriate area, and the amount of ventilation is adjusted. It allows ventilation while maintaining the appropriate temperature in the growing room.

In addition, in the event of an emergency such as an accident, by fully opening the inner and outer rollable curtains, the livestock in the barn can be easily evacuated to the outside through the opening at the lower end.

〔Example〕

FIG. 1 is a perspective sectional view of the livestock barn, and FIG. 2 is a side sectional view of the same.

The livestock barn 1 is a long triangular layered building, consisting of a pair of horizontally long opposing side walls 2, a chevron-shaped wall 3 extending from the upper ends of these walls to form a roof, and a space surrounded by these walls. It is composed of end walls 4 that close both ends. The inside of the livestock shed 1 is partitioned into upper and lower parts by a horizontal ceiling 5 provided at the upper end of the side wall 2, and the lower space forms a room 6 in which the livestock grow. A ventilation hole 8 is provided in both end walls 4 of the attic 7, and an outside air intake fan 9 is attached to the ventilation hole 8 to draw outside air into the attic 7. And on ceiling 5,
A plurality of slits 10 extending in the longitudinal direction are arranged at intervals in the width direction, and the outside air taken into the attic 7 by the outside air intake fan 9 passes through the slits 10 into the room 6 below where livestock grow. It is something that flows inside. The side wall 2 and the chevron-shaped wall 3 have a double wall structure, and the space between the double walls constitutes a discharge path 11 for discharging the air in the room 6 where the livestock grows to the outside. The lower ends of the inner and outer side walls 2 are cut out and opened over the entire longitudinal direction, and curtains 12 and 13 that can be rolled up are provided in each opening. Since these curtains 12 and 13 are rolled up by power or the like, opening and closing operations are easy and labor-saving, and it is preferable to form them from aluminum foil because of their high heat insulation properties.

The method of using these curtains 12, 13 will be explained below. First, the outer curtain 13 is normally kept closed. The inner curtain 12 is constructed as follows, for example. That is, it remains closed when the back is released. During rearing, the curtain 12 is rolled up a little depending on the temperature in the room and the lower end is opened to reduce the amount of ventilation so as not to lower the temperature in the room 6 where the livestock grow too much in the winter. In summer, the curtain 12 is fully opened to increase the amount of ventilation to prevent the temperature in the room from rising too much.

In this way, the air in the room 6 where the livestock grows passes from the opening in the inner side wall 2 through the exhaust passage 11 composed of the double wall of the side wall 2 and the chevron wall 3, and then to the outer chevron wall 3. It is discharged to the outside through an opening formed at the top. In addition, 14 is a small mountain-shaped roof provided so as to cover the upper part of the opening at the top of the mountain-shaped wall 3, and 15 is a roof plate that covers the upper surface of the mountain-shaped wall 3.

In the event of an accident such as a power outage, the inner and outer curtains 12 and 13 are fully opened to allow the domestic animals in the room to evacuate to the outside through the opening at the lower end.

〔Effect of the invention〕

As explained above, according to the first invention, the ventilation amount can be adjusted by adjusting the inner rollable curtain and changing the opening area, so that the temperature inside the building can always be maintained constant. Moreover, the adjustment is simple and labor-saving because the curtain is rolled up and lowered. According to the second invention, in addition to the above-mentioned effects, in the event of an accident, the livestock inside the barn can be easily evacuated to the outside by fully opening the inner and outer curtains that can be rolled up. , the work is also easy.
