In China, there are many farms or factories that need to maintain good ventilation, and large-volume exhaust fans are often used as ventilation equipment. Its stability is very strong, and its life span can even reach8-10In order to reduce the occupied volume of the fan, it will be installed directly on the wall. After a long period of use, a large amount of fluff and dust will stick, and the exhaust fan is generally electrically driven. Only when it is removed can a good washing operation be performed. The disassembly process is cumbersome and is not conducive to cleaning. The agricultural and animal husbandry fan installs a cleaning device in the casing, and uses the cleaning device to clean the fan, thereby reducing the number of disassembly and assembly of the casing.

The casing, the fan body and the cleaning device. The body is installed inside the casing and connected to the casing through several fixing frames; the cleaning device is located at the rear of the fixing frame. An airflow channel connected to the air blowing nozzle, and there is an inclined angle between the air blowing nozzle and the rotating rod.

A limit groove is provided on the casing of the farming and animal husbandry fan, and the end of the rotating rod is slidingly connected to the limit groove.

A rotating shaft and a small motor connected to the rotating shaft are provided in the middle of the rotating rod.

The distance between adjacent blowing nozzles is the same, the number of blowing nozzles is four, and the inclination directions of the blowing nozzles located at the upper and lower ends of the rotating rod are opposite.

The middle part of the rotating rod is provided with a movable joint connected with the air flow channel, and the angle between the air blowing nozzle and the rotating rod is10-25°.

The fan body includes a motor and a number of arc-shaped blades connected to the output end of the motor. Each arc-shaped blade surface is provided with a number of reinforcing ribs, which are distributed along the airflow direction.

The number of curved blades is5-9The material of the curved blades and the shell of the agricultural and animal husbandry fans are both FRP.

The middle of the fixing frame is provided with a wire groove, and a wire fixing clamp is provided on the wire groove.

The middle of the fixing frame is provided with a wire groove, and a wire fixing clamp is provided on the wire groove.

Positioning plates are respectively arranged on the left and right sides of the casing, and the positioning plate and the casing are welded and formed.
