Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention ventilates the air blown from the ceiling without providing any window, and reliably prevents the inflow of sunlight to distinguish between day and night by turning on and off the artificial lighting device. The present invention relates to a ventilation system for a poultry house in which chickens are bred and laid under optimal conditions by accurately controlling temperature and humidity.

[0002]

2. Description of the Related Art As is well known, in a windowless poultry house in which a large number of cages for laying a plurality of laying chickens are set up, down, left and right, a high capacity is required to ventilate the air inside. Ventilation equipment is required. As a conventional ventilation device for the above-mentioned windless poultry house, one described in Japanese Patent Application Laid-Open No. 9-273236 proposed by the applicant of the present patent application is known. In this conventional example, an L-shaped protection frame body is provided on the outside of the exhaust port formed at the upper end of the wall surface, and the protection frame body prevents wind, rain, and solar rays from entering from the exhaust port. .

[0003]

However, even in the above-mentioned conventional poultry house, not only the sun rays and reflected rays but also the inflow of wind and rain cannot be reliably prevented, and a constant ventilation state cannot be maintained at all times. That is, if the sunlight directly or even a small amount of reflected light flows into the poultry house, it is impossible to distinguish the light and dark from the chickens, and therefore it is not possible to provide the optimal conditions for raising the chickens. Therefore, the breeding environment of the breeding chickens is lowered and the physical condition is impaired. Especially when the poultry house has a gable roof, long exhaust ports are formed on the left and right along the length of the eaves.
When the strong sunshine in the daylight reflects inside the gutter several times and flows into the poultry house, the reflected light changes the adjustment of the brightness by artificial lighting, and as described above, breeding especially near the exhaust port. It is not possible to give optimum conditions to chickens.

If the inside of the poultry house is not sufficiently ventilated,
The temperature and humidity cannot be controlled accurately.
In other words, the outside air temperature may change significantly during seasonal changes or day and night, and in that case, the radiant heat from the roof and walls changes the internal temperature of the poultry house. The temperature may be above or below the specified temperature, which is not suitable for raising chickens, and the egg-laying rate of the raised chickens may decrease or the chickens may die. Therefore, an object of the present invention is to prevent the inflow of sunlight or reflected light or wind and rain from the exhaust port of a poultry house, and to allow sufficient ventilation inside.

[0005]

In order to achieve the above-mentioned object, the present invention provides an indoor side and an outdoor side at the upper part of the wall surface of a poultry house where the inside is lifted by the air blown into the room from the outlet formed on the ceiling surface. Forming an exhaust port that communicates with the upper surface of the wall surface on the outdoor side, a bottom surface portion and a side surface portion, and an upper surface portion that extends in a folded shape from the upper end of the side surface portion to the bottom surface portion side,
And a light-shielding frame body having a shielding piece that hangs downward from the tip of the upper surface portion so as to cover the outside of the exhaust port, and the upper end portion of the side surface portion of the light-shielding frame body from the exhaust port. Lower end of the shielding piece by extending above and beyond the eaves of the roof of the poultry house, and by extending the tip of the upper surface to a position above the ridge side from the tip of the eaves of the roof The exhaust opening formed between the upper surface of the eaves and the eaves is capable of exhausting an amount equal to or more than the amount of air blown into the room from the outlet.

According to a second aspect of the present invention, the total area of the exhaust openings is made larger than the total area of the blowout openings, so that the exhaust opening is equal to or more than the amount of air blown out into the room. Exhaust is possible in quantity.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The poultry house 1 of the present invention has left and right wall surfaces 2, 2, an upper gabled roof 3, a ceiling 4 and front and rear gable surfaces (not shown), and the poultry house is composed of the left and right wall surfaces 2, the ceiling 4 and the gable surface. The interior 5 is surrounded. In the interior 5 of the poultry house 1, a large number of cage rows are arranged in which cages a for raising chickens inside are arranged in a multi-tiered manner on the left and right.

On the wall surface 2, horizontal crosspieces 22 are vertically arranged on the outdoor side of a pillar material 21 standing upright from the basic part of the poultry house, and a wall plate 23 is provided on the outdoor side of the horizontal crosspiece 22. Watertight,
It is a liquid-tight construction. Therefore, in the wall surface 2, the wall plate 23 partitions the outdoor side and the indoor side. A heat insulating material may be attached to the inner surface of the wall surface 2.

On the roof 3, purlins 31 are installed at appropriate intervals from the ridge toward the eaves, and rafters 32 are fixed on the top of the purlins 31 so as to be orthogonal to the purses 31.
A roof plate 33 is densely roofed on the upper surface of the rafter 32. Therefore, the roof 3 includes the roof plate 33.
It is also possible to partition the outdoor side from the indoor side and additionally install a heat insulating material on the indoor surface of the roof plate 33.

The wall plate 23 of the wall surface 2 is stretched to the lower surface of the purlin 31 at the eaves tip portion 34 of the roof 3, but is stretched in the range of the heights of the purlin 31 and the rafters 32. Absent. Therefore, between the upper end of the wall plate 23 and the lower surface of the roof plate 33, in the range of the height of the purlin 31 and the rafter 32, the exhaust port 24 that communicates the outdoor side with the indoor side is provided. Is configured along the eaves portion 34. And
The eaves tip portion 34 extends from the wall surface 2 to the outside of the room, and a downward draining light-shielding plate 35 is provided at the outdoor end of the eaves tip portion 34. The roof 3 of the poultry house in the snowy area has the eaves tip portion 3 on the roof surface.
A snow stopper 36 is installed at a position near 4.

The ceiling 4 is located below the roof 3 on the indoor side, and a plurality of air outlets 41 are formed in slits along the length of the poultry house 1 to form a side wall between the roof 3 and the ceiling 4. The inner wall portion 42 located on the indoor side of the column member 21
To provide. Therefore, a ventilation duct 43 surrounded by the roof 3 on the upper side, the ceiling 4 on the lower side, and the inner wall portions 42 on the left and right sides is formed on the back of the ceiling.
Is the inside 5 of the poultry house 1 by the air outlet 41.
Communicate with. The interior side of the exhaust port 24 is the inner wall portion 4
Although it is covered by 2, there is an interval corresponding to the thickness of the pillar material 21 and it communicates with the inside 5 of the poultry house 1, so the inside 5
And the outdoor passage.

According to the present invention, a light shielding frame 51 is provided above the outdoor side of the wall surface 2 so as to cover the outdoor side of the exhaust port 24. The light shielding frame body 51 is provided on the upper portion of each of the column members 21 so as to project to the outside of the room.
The gutter member 53 is hung over the character-shaped support fitting 52 and fixed by bolts, spot welding, or the like, and is configured along the length direction of the wall surface 2.

The gutter material 53 is formed by bending a metal plate material, and has a bottom surface portion 54, a side surface portion 55 provided upright on the outer edge of the bottom surface portion 54, and an upper end of the side surface portion 55. An upper surface portion 56 extending in a folded manner from the bottom surface portion 54 side,
It is a frame shape having a shield piece 57 that hangs downward from the upper surface portion 56.

In a state in which the gutter member 53 is provided on each of the pillar members 21 and is suspended and fixed to the supporting metal fittings 52 arranged in parallel, the bottom face portion 54 is located below the exhaust port 24,
The side surface portion 55 stands upright away from the tip of the eaves portion 34, and the upper end is located above the eaves portion 34. Further, the upper surface portion 56 extends to an upper position on the ridge side from the tip of the eaves tip portion 34 so that the tip is located above the extension line of the wall surface 2, and the shield piece 57 is provided.
By making the snowfall closer to the snow stopper 36, a long exhaust opening 58 is formed along the eaves tip 34 between the lower end of the shielding piece 57 and the eaves tip 34 of the roof.

Therefore, the outdoor side of the exhaust port 24 is sufficiently covered by the light shielding frame 51, but the interior 5 of the poultry house 1 is continuous to the outdoor side by the exhaust port 24 and the exhaust opening 58. In such a configuration, if the exhaust port 24 and the exhaust opening 58 can be exhausted in an amount equal to or more than the amount of air blown from the outlet 41 to the inside 5 of the poultry house, the ventilation of the inside 5 will be remarkably good. The inside 5 does not have an extreme lifting pressure and no air accumulation occurs.

For that purpose, the total area of the exhaust port 24 and the exhaust opening 58 is made larger than the total area of the blowing port 41. Specifically, for example, the length of the poultry house is L
1, the three outlets 41 are formed on the ceiling 4 along the entire length in the length direction of the poultry house and each has a width of L2, and the poultry house is a gable roof, and the exhaust port 24 and the exhaust opening part 58 are provided on the left and right. If the width of the exhaust port 24 or the exhaust opening 58, whichever is the narrower, is L3, which is formed over the entire length of the poultry house, 3 x L1 x L2 ≤ 2 x L1 x L3. Since the total area of the outlet 24 and the exhaust opening 58 is larger than the total area of the outlet 41, ventilation is extremely good.

Although the present invention has been described above based on the embodiments shown in the drawings, the present invention is not limited to the above-mentioned embodiments, and how can be changed unless the configuration described in the claims is changed. But it can be done.

[0018]

In summary, according to the present invention, an exhaust port communicating between the inside and the outside of a poultry house where the inside is lifted by the air blown into the room from the outlet formed on the ceiling surface. And a bottom surface portion and a side surface portion above the outside of the wall surface, and a top surface portion that extends in a folded shape from the upper end of the side surface portion to the bottom surface portion side, and hangs downward from the tip of the top surface portion. A light-shielding frame body having a shielding piece so as to cover the outside of the exhaust port is provided, and the upper end portion of the side surface portion of the light-shielding frame body is located above the exhaust port and above the eaves of the roof of the poultry house. It is formed between the lower end of the shielding piece and the upper surface of the eaves portion by extending upward and extending the tip of the upper surface portion to a position above the ridge side from the tip portion of the eaves portion of the roof. The air that blows out the exhaust opening from the outlet into the room. Characterized in that it possible to exhaust in an amount greater than or equal to.

Therefore, the exhaust port and the exhaust opening for exhausting the air in the poultry house are sufficiently covered with the light-shielding frame body. Therefore, especially when the exhaust opening faces the south side,
Also, in the case of facing north, the upper surface and the shielding piece can surely shield direct sunlight, and even if the light irradiating the exhaust opening is reflected on the inner surface of the upper surface, The side parts are reflected in multiple stages and cannot flow into the poultry house. Further, even if a strong wind blows on the exhaust opening, it does not flow into the interior from the exhaust port as a vortex in the inner space of the eaves, the upper surface and the side surface due to the shielding piece. Moreover, even if the rain blows against the exhaust opening along with the strong wind, it becomes a vortex like the above and is transmitted through the gutter and discharged. For these reasons, the natural environment is not affected even inside the poultry house, particularly near the exhaust port, and the best environment for raising chickens can be provided.

By making the total area of the exhaust opening larger than the total area of the outlet, the exhaust opening can be exhausted in an amount more than the amount of air blown into the room from the outlet. Not only can the inside be reliably ventilated, the air can be cleaned, but the temperature and humidity can be controlled with high precision.

It should be noted that if the inner surface of the gutter material is treated with black or a dark color, it is difficult for the reflected light of the sun to flow into the poultry house, and if a snow stopper is provided on the roof of the poultry house in the snowy area, the exhaust opening will be provided. If it is made closer to or the drowning light-shielding plate is drooped inside the gutter, the reflected light of the sunlight and the wind and rain can be more surely blocked.
