Ventilation system capable of regulating temperature of chicken house

Abstract

The invention discloses a ventilation system capable of regulating the temperature of a chicken house. The chicken house includes a first wall body and a second wall body. The ventilation system includes several ventilation devices and several exhaust fans; each ventilation device includes a ventilation pipe and a ventilation body, wherein the ventilation pipe penetrates through the first wall body and the ventilation body is arranged at any end of the ventilation pipe and is communicated with the ventilation pipe; one end of each ventilation body is a small hole end, the other end of each ventilation body is a big hole end, each small hole end is detachably connected with the corresponding ventilation pipe, each big hole end is provided with a water inlet and a water outlet, and each ventilation body is internally provided with a wet curtain of a honeycomb structure; exhaust fans can pump air in the chicken house out from the chicken house; when the temperature in the chicken house is more than 27 DEG C, the big hole end of each ventilation body faces toward the outside of the chicken house, and when the temperature in the chicken house is less than 21 DEG C, the big hole end of each ventilation body faces toward the inside of the chicken house. The system can effectively regulate the temperature of the chicken house, improve the ventilation effect, meanwhile save energy and improve the feeding efficiency of chickens.

Description

technical field [0001] The invention relates to the technical field of poultry breeding equipment, in particular to a ventilation system for adjusting the temperature of a chicken coop. Background technique [0002] Chickens have no sweat glands, their body surface is covered with feathers, their ability to self-regulate their body temperature is poor, and they are particularly sensitive to ambient temperature. The optimum temperature for laying hens is 24-27°C, while that for breeding laying hens is 21°C. In this temperature range, better economic benefits for laying eggs can be obtained. When the ambient temperature of the chicken house is higher than 27°C, the body temperature of the chickens often rises, the metabolism is slow, the feed intake is reduced, the drinking water is increased, the weight gain of the young chickens is lowered, the sexual maturity of the backup hens is delayed, and the endocrine of the body is reduced. Egg production decreased, or even stopped ...

AI Technical Summary

Problems solved by technology

However, this device has its limitations: in summer, the cooling effect of the cooling pad is limited by the local temperature, the material of the cooling pad, the volume of the water storage container of the cooling pad, the internal volume of the chicken house, the power of the exhaust fan, etc.

In winter, because the inside of the wet curtain is hollow, if the exhaust fan rotates too fast, it will directly draw the external cold air into the chicken house, causing the temperature in the chicken house to drop for a short time, and it is easy to break out infectious bronchitis, mycoplasma and other respiratory diseases, which will affect the species. chicken performance

If the speed of the exhaust fan is too slow for heat preservation, the air in the chicken house will be dirty and the ventilation will be poor, which will still cause the chickens to get sick and affect the production performance
