[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a vertically-ventilated poultry house (also referred to as a tunnel-ventilated poultry house) that ventilates a poultry house for poultry farming by flowing outside air taken in through an air inlet provided on one of the wives in a direction that passes through the poultry house.
[0002]
[Prior art]
In a conventional vertical ventilation house, for example, when the length of the cage row housed inside is about 70 to 80 m or less, the air introduced from one wife face flows in the direction of the other wife face, and the cage row is longer. In such a case, the air introduced from the substantially central portions of both side walls in the longitudinal direction was allowed to flow in the direction of the both wives to ventilate the poultry house.
[0003]
This type of vertical ventilation poultry house has low equipment costs (it is possible to reduce the cost of ventilation-related electric work, which accounts for a large proportion of windless electric work, and it is possible to eliminate the ceiling), and running costs are low (tunnel wind speed effect As a result, the total amount of ventilation per wing is small, the electricity cost of the ventilation fan in the summer is small, there is no dead spot (partial stagnation of the air in the house), and the wind speed in the house is easy to emit. In particular, it has been widely used in poultry houses that use cooling pads.
[0004]
[Problems to be solved by the invention]
In the above-mentioned conventional vertical ventilation house, the air introduced into the house flows gradually while being warmed by the body temperature of the chicken in the cage, so that a temperature difference occurs between the vicinity of the intake and the vicinity of the exhaust, particularly in winter. When the outside air temperature was around 0 ° C., a difference of 10 to 20 ° C. occurred, resulting in an unfavorable environmental condition from the viewpoint of chicken breeding management.
[0005]
In order to address the above problems, the present applicant first provided an auxiliary intake port extending from a substantially central portion of the distance from the intake port to the exhaust port to the upper portion of the longitudinal side walls downstream, The opening and closing and the opening degree of the inlet adjustment plate at the outlet of the auxiliary inlet are adjusted by the signal from the temperature sensor provided in the poultry house before and after the auxiliary inlet (upstream and downstream). We have developed a tunnel-ventilated house that adjusts the amount of air taken in (see Japanese Patent Application Laid-Open No. 9-102).
[0006]
However, the one developed by the present applicant also has a problem that the switching operation of ventilation in both the summer and winter seasons, in particular, the temperature equalization in winter season is not always performed smoothly.
[0007]
The present invention solves the above-mentioned problems of the prior art and those previously developed by the present applicant, especially in winter and summer, especially in winter, in which the temperature around the inlet and outlet in the poultry house is as uniform as possible. become was thus to be able to switch the airflow inside the house smoothly, it has an object to provide a summer-winter switching換縦cross ventilation chicken house.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the summer / winter switching vertical ventilation poultry house according to the present invention takes in outside air from an air inlet provided on one wife side of the poultry house and uses an exhaust fan attached to an exhaust port on the other wife side. In the longitudinal ventilation poultry house to be discharged, an inlet is provided on one of the wives and / or a side surface connected to the wife, and near the inlet of the one wife on the inside of the upper side of the longitudinal side walls of the poultry house. And an air passage extending to a portion corresponding to the end of the cage row close to the exhaust port, the air passage leading to the outside air is provided, and the air passage is provided with an air inlet near the air inlet of the one of the wives. Auxiliary intake ports are provided closer to the exhaust port than the air ports, and an intake adjustment mechanism is provided for each of the intake ports and the auxiliary intake ports provided in the air passages above these side walls, and these intake adjustment mechanisms are provided. From the sensors installed near each inlet and auxiliary inlet Configured to be opened and closed adjusted by temperature, in the summer, these intake air adjusting mechanism, both upper portion of the side wall of the inlets provided in the canal air and auxiliary inlet air port is operated so as to completely close, whereas The air in the poultry house is ventilated only by the air inlet of the wife's face or the side air inlet connected to the wife's face or both of these air inlets, and in winter, the air inlet of one wife's face And completely shut off the air inlet on the side surface connected to the wife surface, and adjust the opening and closing of the air inlet adjusting mechanism according to the temperature sensed from the sensors installed near the respective air inlets and auxiliary air inlets. In this manner, the poultry house can be ventilated only by the adjusted air intake from the air inlet provided in the air passages on the upper side walls and the auxiliary air inlet .
