Description

TECHNICAL FIELD

[0001] The utility model relates to poultry breeding technical field, especially a poultry house ventilation structure and poultry house. BACKGROUND

[0002] At present, the poultry house design widely used in poultry breeding industry, when facing the situation needing small air volume ventilation, the general practice is to rely on the small window on the poultry house wall as the main air inlet. When the negative pressure fan located on the back gable starts to work, a negative pressure environment will be quickly formed in the poultry house, which promotes the fresh air outside to be attracted and penetrated into the poultry house through these small windows. Subsequently, these fresh air will flow naturally in the poultry house, realizing the air exchange in the house and maintaining the normal operation of the poultry life activities.

[0003] However, this ventilation mode may cause some problems under certain conditions. Especially in the northern region or in the cold winter, due to the significant temperature difference between the inside and outside of the house, the cold air entering the poultry house through the small window will directly flow to the cage interior to directly contact the poultry without proper preheating or buffering. This condition is extremely easy to cause the poultry to suffer from cold stress, which may further cause physiological disorder, disease, decreased immunity and other adverse phenomena, threatening the healthy growth of the poultry. SUMMARY

[0004] The poultry house ventilation structure provided by the embodiment of the application can reduce the problem of cold stress caused by the temperature difference between the inside and outside of the house to the poultry, thereby reducing the generation of diseases.

The beneficial effect of this step is that the heat exchange effect of hot and cold air can be improved.

[0014] In one of the embodiments of the present application: the air inlet is directly opposite the passageway between the breeding cages. The beneficial effect of this step is to avoid the air being directly blown above the breeding cages.

[0015] In one of the embodiments of the present application: further comprising: a first fan, the first fan is installed on the shed body, and the first fan is located at the breeding area. The beneficial effect of this step is that the first fan generates negative pressure in the breeding area to suck the warm air in the second heat exchange area into the breeding area, thereby speeding up the air exchange efficiency.

[0016] In one of the embodiments of the present application: further comprising: a second fan, the second fan is installed on the shed body, and the second fan is located at the second heat exchange area. The beneficial effect of this step is that the second fan is started first to generate negative pressure in the second heat exchange area to suck the hot air in the breeding area into the second heat exchange area, thereby improving the heat exchange efficiency.

[0017] In one of the embodiments of the present application: further comprising: a third fan and an air pipe, the side wall is provided with an air outlet and a third air inlet, the air outlet is located below the suspended ceiling, the third air inlet is located above the suspended ceiling, the air pipe communicates the air outlet and the third air inlet, and the third fan is connected with the side wall. The beneficial effect of this step is that the hot air at the bottom of the poultry shed can be sucked into the double-layer top to realize heat exchange, and at the same time, the third fan can generate negative pressure at the bottom of the poultry shed, so that the warm and fresh air at the top can be sucked to the bottom, solving the industry problem of large temperature difference and large air quality difference between upper and lower layers in multi-layer cage breeding.
