Cattle breeding is an important breeding activity in animal husbandry. In the process of cattle breeding, attention should be paid to the breeding environment and feed supply, clean feeding houses, suitable temperature and humidity. The cattle house also needs to have good ventilation, because during the growth of livestock, harmful gases such as feces, carbon dioxide, ammonia, etc. will be produced, so good ventilation equipment is needed to discharge excess water vapor, dust, heat and harmful gases in the breeding house.

[0003] In the prior art, if there are debris in the surrounding environment of the cowshed, these debris may be sucked into the fan in the ventilation structure, resulting in a decrease in the operating efficiency of the fan, and in serious cases, damage to the fan, which requires maintenance personnel to disassemble and maintain; however, common fans are generally fixed to the wall of the cowshed by multiple screws, and the screws need to be screwed multiple times during disassembly and assembly, which is inefficient in maintenance.
