The middle part of the drive shaft 23 is connected through the activated carbon adsorption plate 6 and the ion filter plate 7. One end of the air inlet pipe 3 is provided with a cleaning structure 24 for cleaning the filter screen 8.

[0023] One end of bracket a11 is fixedly connected to the body 1, the top of connecting shaft 19 is fixedly connected to connecting pipe 10, the outer side of rack 17 is slidably connected to bracket b12, connecting pipe 10 forms a rotating structure with bracket a11 through a rotating shaft, and rack 17 and connecting gear a18 form a meshing transmission structure; cleaning structure 24 includes a cleaning rod 242 fixedly connected to one end of transmission shaft 23, and a spring 243 fixedly connected inside the cleaning rod 242; a cleaning brush 244 is fixedly connected to the top of spring 243, and the outer side of cleaning brush 244 slides against cleaning rod 242.

[0024] The ventilation device for livestock that can change the ventilation direction described in this utility model, in order to provide uniform ventilation inside, is activated by starting the induced draft fan 4 and the blower 5, and starting the motor 13 to drive the top actuating plate 14 to rotate. The actuating plate 14 can drive the protrusion 15 to slide in the strip groove inside the connecting plate 16, thereby driving the connecting plate 16 to move back and forth.

When the cleaning brush 244 rotates, it rolls on one side of the arc plate 246 via the roller 245 at its end. When the roller 245 contacts the arc block 247 on one side of the arc plate 246, the roller 245 and the cleaning brush 244 move and compress the spring 243 at one end. When the roller 245 disengages from the spring, the cleaning brush 244 moves. When the arc-shaped block 247 contacts, the spring 243 will reset and push the cleaning brush 244 to move. As the cleaning brush 244 reciprocates with the cleaning rod 242, it will also reciprocate, thereby cleaning one side of the filter screen 8, removing the debris adhering to the filter screen 8, and keeping the filter screen 8 unobstructed. Through the above operation, the ventilation direction of the ventilation device can be changed, so as to provide uniform ventilation inside the pigsty, ensure fresh air in the pigsty, and block pathogens, African swine fever, etc.
