Description

Ultrasonic breathing immunity machine

Technical Field

The invention relates to the technical field of auxiliary equipment of farms, in particular to an ultrasonic breathing immune machine.

Background

With the development of economy, the daily living standard of people gradually rises, and the market demand for meat such as chicken, duck, pork and the like gradually increases. Chickens in a chicken farm are usually raised in a cage raising mode, and the living environment of the cage raised chickens directly influences the economic benefit of chicken farmers. If the carbon dioxide exhaled by the chickens, sulfur dioxide, hydrogen sulfide and other harmful gases generated by excrement in the animal house, and metabolites generated by the chickens such as chicken manure and the like are not properly treated in the chicken farm, a large amount of bacteria can be bred under the action of microorganisms, so that the chickens can be polluted by themselves and polluted by each other, and the growth of the chickens can be influenced. Only when the ideal ecological balance is achieved between the life of the chicken and the living environment of the chicken, the chicken industry can be better developed, and higher economic benefit can be obtained. At present, the disinfection of the environment of a chicken farm is a method for eliminating pathogenic microorganisms, controlling the spread of diseases and establishing benign ecology.
