[0031] A specific application of this embodiment is as follows: When in use, first move the device to the corresponding position, pour the sulfonamide raw material into the outer barrel 1 through the feed port on the barrel cover 101. At this time, the first motor 212 can be started to make its output shaft rotate clockwise. When the output shaft of the first motor 212 rotates clockwise, under the action of the second support 223, the stirring rod two 224 will be driven by the first rotating shaft 211 to rotate clockwise around the output shaft of the first motor 212, and the sulfonamide raw material in the outer barrel 1 will be stirred clockwise. When the first rotating shaft 211 rotates clockwise, the upper inner gear ring 214 located above will be driven to rotate clockwise by the upper partition 213. When the upper inner gear ring 214 rotates, the two gears 218 will be driven to rotate. The rotation of the two gears 218 drives the lower inner gear ring 214 to rotate. The rotation of the lower inner gear ring 214 drives the lower partition 213 to rotate counterclockwise. When the lower partition 213 rotates counterclockwise, the stirring rod one 222 will be driven by the first support 221 to rotate counterclockwise around the first rotating shaft 211, and the sulfonamide raw material in the outer barrel 1 will be stirred counterclockwise. Thus, the sulfonamide raw material in the outer barrel 1 is fully stirred through bidirectional stirring. When feeding is required, the second motor 322 can be started to make its output shaft rotate. When the output shaft of the second motor 322 rotates, the fourth rotating shaft 323 and the first pulley 325 will be driven to rotate. Through the transmission of the belt 327, the rotation of the first pulley 325 will drive the second pulley 326 to rotate. When the second pulley 326 rotates, the third rotating shaft 316 will be driven to rotate. When the third rotating shaft 316 rotates, under the action of the cam 317, the slider 314 will periodically apply pressure to the spring telescopic rod 315, causing it to undergo elastic deformation and generate elastic force. When the convex part of the cam 317 contacts the slider 314, the slider 314 moves downward, and the spring telescopic rod 315 is compressed by the slider 314. When the convex part of the cam 317 moves away from the slider 314, the slider 314 will rebound upward under the elastic force of the spring telescopic rod 315, thereby vibrating the filter screen 311, so that the qualified sulfonamide raw material in the outer barrel 1 falls into the feeding box 312. At this time, under the action of the fourth rotating shaft 323, the sulfonamide raw material in the feeding box 312 will be discharged from the device through the spiral blade 324.
