The filtering mechanism 5 can prevent seeds from being sucked into the interior of the stirring shaft 2 by the fan 4;

[0023] The filter frame 51 can filter the airflow entering the stirring shaft 2 to prevent seeds from entering the stirring shaft 2 along with the airflow. When the stirring shaft 2 rotates, the reciprocating threaded rod 56 rotates along with the stirring shaft 2. When the reciprocating threaded rod 56 rotates, the reciprocating threaded rod 56 moves up and down under the action of the threaded block 57. During the movement of the reciprocating threaded rod 56, the rocker 2 53 will move with it. During the movement of the rocker 2 53, the moving plate 55 will move with it. Under the action of the rocker 1 52, the filter frame 51 will be moved along the side wall groove of the stirring shaft 2 by the moving plate 55. During the movement of the filter frame 51, the seeds attached to the side wall of the filter frame 51 will be scraped off by the blades of the stirring shaft 2, so as to prevent the seeds from adhering to the surface of the filter frame 51 and causing the fan 4 to The working effect is affected, the threaded block 57 is installed on the fan 4, which ensures the working effect of the threaded block 57, the length of the threaded part of the reciprocating threaded rod 56 ensures that the filter frame 51 can move smoothly on the groove of the filter frame 51 installed on the stirring shaft 2, the installation method of the rocker 1 52 and the rocker 2 53 ensures that the reciprocating threaded rod 56 can move with the filter frame 51 when it moves, ensuring the working effect of the filter frame 51, the shape of the through groove of the moving plate 55 ensures that the rotation of the rocker 1 52 will not be hindered, and several connecting rings 54 are arranged on the reciprocating threaded rod 56 to ensure the stability of the reciprocating threaded rod 56 during the movement, and the moving plate 55 is slidably installed on the connecting ring 54 to ensure the stability of the moving plate 55 during the movement.
