[0030] It should be noted that, due to the existing cattle barn exhaust device for feeding cattle, poor air flow results in low exhaust efficiency, insufficient air purification, and difficult to meet high standards, and cleaning and maintenance is complicated and the filter cover is easy to damage. These problems have affected the quality of the cattle barn environment and the health of the cattle. The present scheme significantly improves the air quality and environmental comfort in the cattle barn; the rotatable fan body 2 design ensures uniform and effective air intake and exhaust, expands the exhaust area, improves the exhaust efficiency, and deeply purifies the air through multiple layers of filter elements to remove various harmful substances, creating a fresh and healthy environment for the cattle barn, which is conducive to the health and comfort of the cattle; at the same time, the built-in detection element 18 of the device can monitor and automatically adjust the fan operation in real time, ensuring that the harmful gas concentration is within a safe range, further ensuring the safety and hygiene of the cattle barn; in addition, the adsorption filter cover 4 and the integrated cleaning mechanism outside the fan body 2 are designed to simplify the cleaning process, avoid filter cover wear and tear, and ensure the continuous and efficient operation of the exhaust system, providing a strong guarantee for the healthy growth of the cattle.

[0031] Specifically, in the present embodiment, the present scheme mainly includes a mounting seat 1 and a fan body 2, the fan body 2 is designed to be rotatably mounted on the mounting seat 1, and this rotatable feature allows the fan body 2 to adjust its exhaust direction, thereby expanding the exhaust area in the cattle barn. By adjusting the rotation angle of the fan body 2, the air in the cattle barn can be more effectively extracted. This design not only improves the exhaust efficiency, but also enhances the air flow in the cattle barn, which helps to maintain the cleanliness and comfort of the cattle barn environment. The exhaust end of the fan body 2 is connected to the filter box 3 for sucking air from the cattle barn and purifying it through the filter box 3; the adsorption filter cover 4 is arranged at the suction end of the fan body 2 for preliminary filtration of large particles in the air;

[0032] In order to maintain the cleanliness and filtration efficiency of the adsorption filter cover 4, the device is specially designed with a cleaning mechanism; the cleaning mechanism includes an adjusting frame 5, a lead screw 6, an adjusting block 7, a horizontal guide slot 8, a mounting plate 9, a flexible pad 10 and a cleaning block 11;

[0033] When the adsorption filter cover 4 needs to be cleaned, first rotate the lead screw 6 in the adjusting frame 5; the adjusting block 7 threaded on the lead screw 6 will move along the length direction of the lead screw 6 as the lead screw 6 rotates; since the adjusting block 7 is connected to the horizontal guide slot 8 on the outer surface of the fan body 2 through the mounting plate 9, the movement of the adjusting block 7 will drive the mounting plate 9 to move horizontally;

[0034] The side of the mounting plate 9 opposite to the adsorption filter cover 4 is provided with a flexible pad 10 and a cleaning block 11; when the mounting plate 9 moves horizontally, the cleaning block 11 will wipe the outer surface of the adsorption filter cover 4, thereby removing dust, hair and other impurities attached to the filter cover;
