Description

Technical Field

[0001] The utility model specifically relates to the technical field of poultry breeding, in particular to a poultry breeding factory which can improve the breeding environment. Background Art

[0002] Poultry farming refers to the breeding of poultry such as chickens, ducks, and geese. Chickens, ducks, and geese are one of the sources of meat for people's daily consumption and the demand is huge. Therefore, the scale of chicken, duck, and goose breeding is also large, and large breeding rooms are generally built for breeding.

[0003] The breeding requirements for poultry such as chickens, ducks, and geese are relatively high. Take chicks as an example. When breeding chicks, for economic considerations, farmers generally breed a large number of chicks at the same time, and the chicks will be concentrated in the breeding room. The physical fitness of the chicks is very poor and is greatly affected by the environment. Therefore, environmental factors such as the temperature and air quality in the breeding room need to be strictly controlled. When the air quality is poor, it will seriously affect the growth of the chicks, resulting in a reduction in production; in addition, during the growth process, the chicks will produce feces from time to time. Batches of chicks will produce a large amount of feces. The feces will not only produce a strong odor, but also breed a large number of bacteria. In an environment with more bacteria, the chicks will be infected and sick by bacteria, and in severe cases, it will cause the death of a large number of chicks; the main means of removing feces is to use manual shoveling of feces. Manual shoveling not only increases the workload of poultry breeding, but also easily produces residual feces, so that bacteria will still breed in the breeding room;

[0004] To this end, we provide a poultry farm that can improve the breeding environment. The air quality sensor can monitor the air quality in the breeding room in real time. When the air quality in the breeding room is poor due to a lot of feces, the air quality sensor transmits a signal to the controller. The controller controls the air purification device to release the outside air into the breeding room after purification. At the same time, it can also control the suction of impurities and odors in the breeding room and discharge them into the external environment, thereby completing the replacement of the air inside the breeding room and ensuring the quality of the environment in the breeding room. At the same time, the controller controls the water pump to spray water through the water pipe spray nozzle in the breeding room and flush the feces on the ground into the septic tank. There is no need for staff to manually shovel it, and the cleaning effect is good, which effectively prevents the growth of bacteria. Utility Model Content
