Abstract

PURPOSE:To prevent high temperature in a henhouse in summer time or during no wind by installing a force air discharge fan at a discharge port which is provided in the roof ridge section of a henhouse and introducing fresh air from many air inlets which is provided in the floor. CONSTITUTION:An air discharge port 3 is provided with a forced air discharge fan 9. Below the ridge section 2a of a roof an air discharge baffle 10 is hung to give uniform air convection flow in a henhouse. For an air inlet port 11 means which can be adjusted automatically in response to the rate of working for its dimension, for instance automatic opening and closing air inlet 12 is installed. Normally fresh air is introduced through the air inlet port 11 which is provided under the eave and the air is discharged from an air discharge port 3a to the outside of the henhouse by natural convection flow. In summer time or during no wind if the inside temperature of the henhouse is high, air inlet ports 14 are opened by winding up a double-cloth curtain 13, and a forced air discharge fan 9 which is installed on an air discharge port 3 provided on the ridge section 2a of the roof is driven. With this arrangement fresh air is introduced into the henhouse through many air inlet slits 15 provided in the floor.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ventilation system for a windless chicken house, particularly a ventilation system for a windless chicken house designed to prevent the inside of the chicken house from becoming too hot in summer or in windless conditions. It is.

[Conventional technology] Conventionally, ventilation systems for windless poultry houses include roof,
A poultry house that has a ceiling, side walls, and end walls, houses and raises a large number of chickens, has an exhaust vent in the roof ridge, and has an inlet under the eaves to naturally exhaust air from the roof ridge. It has been known.

[Problems to be solved by the invention] However, in naturally ventilated chicken houses with such a configuration, an exhaust fan is used from an exhaust port provided in the roof ridge to take advantage of the rise in temperature inside the chicken house caused by the heat generated by the chickens. It is economical as it consumes less energy, but it is difficult to maintain the temperature inside the chicken house as the temperature inside the chicken house becomes high in summer or when there is no wind, which affects the egg-laying performance of the chickens. There was a problem.

An object of the present invention is to solve the above-mentioned problems.

[Means for Solving the Problems] In order to solve these problems, according to the present invention, a forced exhaust fan is installed at the exhaust port in the roof ridge, and a forced exhaust fan is installed at the air inlet under the eaves. There is provided a ventilation system for a windless poultry house, characterized in that it is equipped with means for automatically adjusting the opening size in accordance with the operating rate, and a large number of air intake inlets provided in the floor.

[Function] The present invention installs a forced exhaust fan to the exhaust port provided in the roof ridge of a poultry house, and uses a large number of air intake inlets provided on the floor.
Since fresh air is introduced from ~, it is possible to prevent the inside of the poultry house from becoming too hot during summer or when there is no wind. In this way, it is possible to always achieve a certain level of spawning results.

[Example] An example of the present invention will be described in detail below with reference to the drawings.

The middle-floor type windless chicken house 1 shown in FIG.
It consists of an end wall 5 on the gable side and a floor 6.

In this example, a multi-stage cage (7) is installed inside the poultry house.
a, 7b, 7c, and 7d are arranged along the longitudinal direction of the chicken house. A passage 8 is provided along the cage between the cages 1.

A forced exhaust fan 9 for discharging air from inside the poultry house is attached to an exhaust port 3 provided in the ridge 2a of the roof 2 of the poultry house. An exhaust baffle 10 is provided below the ridge 2a of the roof.
is suspended. This baffle prevents the airflow flowing near the cage 1 located below the roof ridge from becoming strong, and helps to ensure uniform convection within the poultry house.

An inlet 11 for natural ventilation is provided under the eaves, from which fresh air is normally introduced. A means for automatically adjusting the opening size in accordance with the operating rate, such as an automatic opening/closing inlet 12, is attached to the inlet 11.

Below the intermediate floor 6 of the side wall 4 is provided a summer air inlet 14 which can be closed by a double curtain 13. Also floor 6
There are many popular pickpockets 7) to 5.

The inlet 14 is opened by rolling up the double curtain 13 when the inside of the poultry house becomes high temperature in summer or in windless conditions.

In the windless poultry house according to the present invention configured as described above, fresh air is introduced through the inlet 1 which is usually provided under the eaves, and together with the air inside the poultry house warmed by the chickens, the roof 2 is heated by natural convection. It is discharged outside the poultry house from a natural ventilation exhaust port 3a provided in the ridge 2a.

When the temperature inside the poultry house becomes high in summer or in windless conditions, the air inlet 14 is opened by rolling up the double curtain 13,
Further, the natural ventilation exhaust port 3a is closed, and the forced exhaust fan 9 attached to the exhaust port 3 provided on the ridge portion 2a of the roof is operated. In this way, fresh air is introduced into the poultry house through the inlet 14 and through the large number of popular slits 15 provided in the floor.

The introduced air replaces the dirty air inside the poultry house.

In this way, as shown by the arrow in Fig. 1, the popular slit 15
Air from the passage 8 arranged between the cage units
The liquid is blown out to create convection within the poultry house, and is discharged from the exhaust port 3 by the forced exhaust fan 9.

In the summer, the roof is scorched by the sun's heat, and the radiant heat heats up the inside of the chicken house, so air is introduced from one inlet for natural ventilation and exhausted from the exhaust outlet 3 along with the air from inside the chicken house. It is desirable to do so.

Although this embodiment describes a middle-bed type windless poultry house, the present invention can also be applied to a low-bed type and a raised-bed type windless poultry house.

[Effects of the invention] Since the windless poultry house according to the present invention can use both natural ventilation and forced ventilation, ventilation is normally performed by natural convection. Since the forced exhaust fan 9 is operated to perform forced ventilation, it is possible to prevent the inside of the poultry house from becoming high temperature. In this way, a decrease in the egg production rate of chickens can be avoided. Moreover, the forced exhaust fan is only operated in summer or in windless conditions, which can keep power consumption low.

In this way, necessary and sufficient ventilation can be provided throughout the year, whether in winter or summer.
