Resistance rotation type material level switch fan blade

The utility model discloses a rotation resistance type material level switch fan blade which comprises a sheet-shaped fan blade body, the fan blade body has a first direction and a second direction, a rotation axis is arranged in the middle of the fan blade body in the first direction, a balance weight piece is arranged on one side of the fan blade body in the first direction, and the balance weight piece enables the gravity center of the fan blade body to deviate from the rotation axis of the fan blade body. The counter weight on one side of the fan blade body is additionally arranged, so that light powder can press the fan blade body more easily to force the spring to act when reaching the material level, the rotation resistance type material level switch stops running, and frequent false alarm caused by too light powder due to pipeline limitation is reduced. 本实用新型公开了一种阻旋式料位开关扇叶，包括片状的扇叶本体，扇叶本体具有第一方向和第二方向，扇叶本体上第一方向的中部为旋转轴线，所述扇叶本体上第一方向的一侧设置有配重件，配重件使扇叶本体的重心偏离其旋转轴线，本实用新型增加扇叶本体一侧的配重，使较轻的粉料到达料位时更易压住扇叶本体来迫使弹簧动作，阻旋
