Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) This invention relates to a ventilation method for ventilating a poultry house in which chickens are raised.

(Prior art) In recent years, broilers, egg-laying hens, f! In order to improve productivity, chicks such as TI chickens are raised by laying bedding in a long and narrow chicken house and letting a large number of chicks roam there. However, when using this breeding method, it is necessary to properly control temperature and humidity until the chicks are about 5 days old, but after that point, ensuring sufficient ventilation in the chicken house has a significant impact on the growth of the chicks. It is said that

For this purpose, conventionally, as shown in FIG. 3, a plurality of intake windows 2 are provided in one side wall 1a of the pair of side walls 1a and lb extending in the longitudinal direction of the poultry house 1, and the intake windows 2 are 2, a plurality of exhaust windows 3 are provided on the other side wall 1b, and each of the exhaust windows 3 is provided with an exhaust fan 4. When the exhaust fans 4 operate, the poultry house 1 is removed from the intake window 2. A ventilation method is used in which outside air is taken in and the air inside the poultry house 1 is exhausted to the outside through the exhaust window 3.

In this conventional method, in order to maintain the inside of the poultry house 1 at approximately a predetermined temperature, the ventilation state inside the poultry house 1 is adjusted by adjusting the opening 1!1ffi of the intake window 2.

(Problems to be Solved by the Invention) In such a conventional ventilation method, when ventilation is performed with the opening amount of the intake window 2 being reduced, air is forced into the chicken house 1 from the intake window 2. Since the inhalation generates a thin flow inside the poultry house 1, ventilation is effectively performed throughout the poultry house 1. However, when ventilation is performed with the intake window 2 opened to a large extent, the third As shown by the arrow in the figure, air flows straight from the intake window 2 toward the exhaust J3, and air stagnation occurs around this airflow, resulting in extremely poor ventilation efficiency throughout the poultry house. .

When uneven ventilation occurs in areas where air flows straight, the temperature locally drops and the airflow hits the chicks directly, making them more susceptible to bronchial diseases. Areas where this occurs are susceptible to bacterial diseases, and mosquitoes tend to accumulate there, facilitating the spread of disease.

Structure of the Invention (Means for Solving the Problems) The present invention has been made by focusing on the above-mentioned problems, and includes a pair of side walls 1a extending in the longitudinal direction of the poultry house 1 and facing each other; 1blC A plurality of intake windows 2 are provided, and an exhaust fan 4 is provided on one adjacent wall 1c adjacent to the side walls 1a and 1b and extending in a direction perpendicular to the longitudinal direction of the poultry house 1. By operating the 7-n 4, outside air is taken into the poultry house 1 through each intake window 2, and the air inside the poultry house 1 is exhausted to the outside through the exhaust fan 4.

(Function) Therefore, according to the ventilation method of the present invention, the air sucked into the poultry house 1 through the intake window 2 does not flow straight to the exhaust fan 4 side, and can be uniformly and effectively throughout the poultry house 1. Ventilation can be provided and the bronchial system and l
It is possible to reliably prevent the risk of contracting a sexually transmitted disease, and also to suppress damage caused by mosquitoes.

(Example) Hereinafter, an example of a poultry house embodying this invention will be described in 1st and 2nd examples.
This will be explained according to the diagram.

In this embodiment, a plurality of intake windows 2 are provided in a pair of opposing side walls 1a and 1b extending in the longitudinal direction of the elongated poultry house 1, respectively. Said both side wall parts 1a, Ib
A plurality of exhaust windows 3 are provided on the adjacent wall 1c that extends in a direction perpendicular to the longitudinal direction of the poultry house 1, and an exhaust fan 4 is attached to each of the exhaust windows 3. .

As shown in FIG. 2, a swing door 5 and a blind 6 are attached to each intake window 2. Furthermore, a pair of guard plates 7 are arranged upright on the floor of the poultry house 1 at a predetermined interval from both longitudinal ends thereof, and bedding is spread on the floor between the guards Ifi 7 to raise chicken chicks. It looks like this.

Furthermore, in this embodiment, as shown in FIG. 1, a temperature sensor 8 is provided on the inner surface of one side wall 1a of the poultry house 1, and detects the temperature inside the chicken @1. The exhaust fan 4 is rotated at a low speed, and when the temperature is high, the exhaust fan 4 is rotated at a high speed.

Now, in the poultry house configured as described above, when the exhaust fan 4 is operated, both side walls 1a are removed.

Air is taken into the poultry house 1 through each intake window 2 provided in the poultry house 1b, the inside of the poultry house 1 becomes negative pressure, and the air is transferred to the exhaust fan 4 side on the adjacent wall 1c as shown by the arrow in Fig. 1. After that, it is exhausted outside the poultry house 1 through the exhaust window 3.

Therefore, the air flows straight from the intake window 2 to the exhaust fan 4 side, and there is no local stagnation of air, and the air from the intake window 2 is dispersed and flows slowly, and the air flows throughout the poultry house 1. ventilation evenly and effectively throughout the area. Therefore, in areas where air flows straight, chicks are more susceptible to bronchial diseases, and in areas where air stagnates, chicks are more susceptible to bacterial diseases, and mosquitoes gather. You can raise chicken chicks in good health without any problems.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be modified and embodied as follows.

(1) Based on the temperature detected by the temperature sensor 8 in the embodiment, the rotation speed of the exhaust fan 4 is configured to be changed in three stages of low speed, medium speed, and high speed, or steplessly.

(2) The exhaust fan 4 is composed of an appropriate number of large fans and small fans, and the start/stop of the small fans is controlled based on temperature detection by the temperature sensor 8, so that the temperature inside the poultry house 1 is below a predetermined value. When this happens, the small fan or the large fan is stopped and ventilation is performed by only one of them, and when the temperature inside the poultry house 1 exceeds a predetermined value of 6 m, ventilation is performed by the large and small fans.

(3) Changing the planar shape of the poultry house to a shape other than the above example.

Structure of the Invention As detailed above, the present invention is capable of uniformly and effectively ventilating the entire inside of the poultry house without the air sucked into the poultry house through the intake window flowing straight to the exhaust fan side. This has the excellent effect of reliably preventing the chicks from contracting bronchial or bacterial diseases, as well as suppressing damage caused by mosquitoes.
