Description

[Detailed Description of the Invention] This invention relates to a ventilation system for a poultry house, which blows air down into the gap between the left and right cages arranged inside the poultry house, and directs the air flow to the feeder in front of the feed gutter. It is horizontally guided by a face plate and circulated within each cage to eliminate odors and is effective for the health of chickens.

As is well known, poultry houses have a large number of cages arranged vertically in multiple layers. It is difficult to distribute the odor evenly, and the odor inside the cage, especially in the corners and bottom, cannot be sufficiently exhausted.

In addition, if air circulation is poor, fresh outside air will not be supplied to the poultry house, and the chickens will not receive sufficient oxygen, which will have a negative impact on the health and growth of the chickens.

The present invention has been proposed in view of the above, and consists of installing multiple layers of left and right cages vertically in a poultry house in an antipodal manner with a gap between them, and connecting feed troughs to the left and right cages within the gap. The front plate of the bait gutter is tilted forward to serve as an air guide plate, and an air outlet is opened downward above the gap, and the air outlet is installed in the attic. A blower for forcibly supplying outside air into the air storage chamber is installed on the end plate of the air storage chamber, and the outside air supplied into the air storage chamber by the blower is blown downward from the air outlet and passed into the gap. The bait is guided laterally by the front plates of the left and right bait troughs.

Hereinafter, the present invention will be described with reference to the embodiments shown in the drawings, in which a large number of cages 2, 2',
2'' and 3, 3', 3'' are arranged side by side in upper and lower three layers with a gap D between them.

In the gap D, there is a feed gutter 4 for each cage 2.
4' and 4'' extend in opposite directions, respectively.

Each bait trough 4 has a front plate 5, 5', 5'', which is tilted forward to serve as an air guide plate, and the front plates 5, 5 facing each other are A gap 7 is formed between them.

Further, above the gap D, in other words, in the ceiling above the gap 7, slit-shaped air outlets 6 are opened vertically downward in a series or at appropriate intervals to create an air reservoir utilizing the space in the attic. Connect to 8. A blower 10 for forcibly supplying outside air into the air storage chamber 8 is provided on the end plate 9 of the air storage chamber 8.

To ventilate the inside of the poultry house 1 using the ventilation system for the poultry house according to the present invention, the blower 10 is operated to forcibly supply outside air into the air storage chamber 8 . The outside air supplied into the air storage chamber 8 is blown out vertically downward from the air outlet 6. The blown outside air flows downward through the interval D, and a part of the outside air is guided by the slope of the front plate 5 of the upper bait gutter 4, changes its direction laterally, and flows horizontally inside the cages 2 and 3 at the left and right positions. pass through.

Also, a part of the outside air blown out from the air outlet 6 passes through the gap 7 between the upper right and left bait troughs 4, 4 and descends, and the front plate 5' of the middle tier bait troughs 4', 4',
Guided by the slope 5', it changes its direction laterally and passes horizontally through the cages 2' and 3' at the left and right positions in the middle row.

Furthermore, a part of the outside air blown out from the air outlet 6 passes through the upper gap 7 and the middle gap 7' and descends to the front plate 5'' of the lower bait gutter 4'', 4''.
It is guided by the slope of 5'', changes its direction laterally, and passes horizontally through the cages 2'' and 3'' at the lower left and right positions.

The air blown vertically downward from the air outlet 6 in the above manner flows into all the cages 2, 2',
2'', 3, 3', 3'' in the horizontal direction, the odors from the chickens and excrement in each cage 2... are completely eliminated by the flowing air.

The air containing the odor is removed from the wall 1 of the poultry house 1.
It is discharged to the outside from the exhaust hole 12 provided in 1 and others.

Note that the gap D may be wide enough that a person cannot pass through. In order to supply bait to the bait troughs 4, 4', 4'', an automatic feeding device (not shown) that moves each bait trough 4, . . . in parallel may be used.

The ventilation system for a poultry house according to the present invention is a poultry house in which a large number of cages are arranged vertically in multiple layers. Due to the correlation, the outside air blown out by the front plate of the bait gutter is guided laterally so that it flows horizontally inside all the cages, so the structure is simple and there is no need for a duct to guide the outside air. Therefore, it is possible to provide a ventilation system for poultry houses that is easy to construct and inexpensive. Furthermore, according to the present invention, it is possible to uniformly supply outside air into the poultry house and to sufficiently ventilate even the corners and lower cages, so that odors generated from chickens and excrement can be completely eliminated. And since fresh outside air is constantly supplied, it is effective for managing the health of chickens.
It grows quickly and is economically effective.
