Description

TECHNICAL FIELD

[0001] The utility model relates to pig farm exhaust technology field, concretely is adjustable pig farm exhaust device. BACKGROUND

[0002] The breeding industry is a production department that uses the physiological functions of animals such as livestock and poultry that have been domesticated by humans, or wild animals such as deer, musk deer, foxes, minks, otters, and quails, to convert plant energy such as pasture and feed into animal energy through artificial feeding and breeding, in order to produce meat, eggs, milk, wool, cashmere, leather, silk, and medicinal materials. It is an extremely important link in the exchange of material between humans and nature. In a pigsty in a pig farm, multiple pigs are enclosed, and in hot weather, the temperature inside the pigsty can be very high, so an exhaust device is usually used to dissipate heat inside the pigsty. According to the principle of thermal expansion and contraction, the heat generated inside the pigsty will accumulate above the pigsty, so the exhaust device is usually installed on the roof of the pigsty.
