[0002] The structure of the air guide device is a structure often used in agricultural machinery diesel engines. The structure of the air guide device is generally equipped with an air guide body and a power mechanism, and the air guide body is driven to rotate through the power mechanism. It is inevitable that some dust particles will be brought in during work, and the existing air guiding device lacks a mechanism that can deal with these dust particles in time. The filter screen is blocked, thereby affecting the use effect of the filter screen. In addition, the existing air guide device will generate a lot of noise during use, which will cause inconvenience to the user, and the user needs to move the entire air guide device when he wants to change the wind direction. Inconvenient to operate
