[0059] Among them, the scraper 20 is adapted to the storage tank 4;

[0060] Among them, a plurality of anti-blocking rods 15 are fixedly connected to the outer surface of the fixed shaft 7, and the anti-blocking rods 15 are located in the connecting pipe 3;

[0061] The fixed disk 17 is fixedly sleeved on the outer surface of the fixed shaft 7;

[0062] The lower surface of the fixing plate 17 is slidably connected to the upper surface of the mounting plate 14 .

[0063] Furthermore, two mirror-image rotating plates 16 are fixedly connected to the outer surface of the fixed disk 17;

[0064] The lower surface of the rotating plate 16 is slidably connected to the upper surface of the mounting plate 14;

[0065] The rotating plate 16 is fan-shaped and is adapted to the through slot 18 .

[0066] Wherein, the motor 12 is fixedly connected to the upper surface of the storage tank 4;

[0067] Wherein, the mounting shaft 13 is fixedly connected to the rotating output shaft of the motor 12;

[0068] The mounting block 8 is fixedly connected to the upper end of the fixed shaft 7 .

[0070] Wherein, the sliding block 10 is fixedly connected to the upper surface of the fixed plate 11;

[0071] The mounting chute 9 is provided on the upper surface of the mounting block 8 and extends out of the lower surface of the mounting block 8;

[0072] The sliding block 10 extends into the installation slot 9 , and the outer surface of the sliding block 10 is slidably connected to the inner wall of the installation slot 9 .

[0073] Furthermore, in this solution, in the initial state, in this solution, the motor 12 is a motor with a self-locking function, such as a conical rotor motor, etc., and the rotating output shaft of the motor will self-lock after the power is cut off, so that the rotating output shaft of the motor cannot rotate;

[0074] Furthermore, in this solution, when in use, the pharmaceutical intermediate is poured into the storage tank 4 through the fixed pipe 5, and the pharmaceutical intermediate enters the storage tank 4 and the connecting pipe 3. Because in the initial state, the two rotating plates 16 are located directly above the two through grooves 18, so that the two rotating plates 16 block the two through grooves 18. At this time, the rotating plate 16 and the mounting plate 14 cooperate to prevent the pharmaceutical intermediate from falling from the through grooves 18 into the screening device body 2, and then the pharmaceutical intermediates that need to be screened can be poured into the storage tank 4 for storage at one time. At this time, the synchronous starting motor 12 and the screening device body 2 are started. The screening device body 2 is started so that the screening device body 2 vibrates up and down, and the motor 12 starts to drive the fixed plate 11 and the sliding block 10 to rotate around the mounting shaft 13, and the sliding block 10 rotates with the mounting slot 9 during the rotation. In this process, the mounting block 8 is pushed to rotate around the fixed shaft 7. The fixed shaft 7 is driven to rotate back and forth in a fan-shaped manner, and the rotation of the fixed shaft 7 synchronously drives the stirring rod 19, the scraper 20, the connecting rod 21, the anti-blocking rod 15, the mounting plate 14, and the rotating plate 16 to rotate back and forth synchronously. The rotating plate 16 is dislocated with the through slot 18 during the rotation process, so that the pharmaceutical intermediates in the storage tank 4 and the connecting pipe 3 can fall downward into the screening device body 2 through the through slot 18, thereby realizing the unloading of the pharmaceutical intermediates in the storage tank 4 without manual unloading. In addition, the cover 6 can be covered on the fixed pipe 5 during the unloading process to achieve full sealing during the unloading and screening process of the pharmaceutical intermediates, thereby preventing the pharmaceutical intermediates from floating out of the fixed pipe 5 during the unloading or screening process, optimizing the production environment, thereby avoiding the waste of raw materials, and being safer and more hygienic, thereby ensuring the quality of raw material production, thereby increasing the practicality of the screening device;

[0075] As mentioned above, the starting motor 12 drives the scraper 20 to rotate back and forth in a fan shape. During this process, the scraper 20 can scrape the inner wall of the storage tank 4 to prevent the pharmaceutical intermediate from adhering to the inner wall of the storage tank 4, thereby avoiding the waste of the raw material drug and increasing the practicality of the screening device.

[0076] As mentioned above, when in use, the stirring rod 19 can stir the pharmaceutical intermediate in the storage tank 4, and the anti-blocking rod 15 can stir the pharmaceutical intermediate in the connecting pipe 3, thereby avoiding blockage of the storage tank 4 and the connecting pipe 3, thereby ensuring the smoothness of the discharge of the pharmaceutical intermediate, and thereby increasing the practicality of the screening device.

[0077] Furthermore, in this solution, the sliding block 10 drives the mounting block 8 to rotate at an angle greater than ninety degrees.

[0078] Working principle: When the device is in use, the pharmaceutical intermediate is poured into the storage tank 4 through the fixed pipe 5, and the pharmaceutical intermediate enters the storage tank 4 and the connecting pipe 3. Because in the initial state, the two rotating plates 16 are located directly above the two through slots 18, so that the two rotating plates 16 block the two through slots 18. At this time, the rotating plate 16 and the mounting plate 14 cooperate to prevent the pharmaceutical intermediate from falling from the through slots 18 into the screening device body 2, and then the pharmaceutical intermediates that need to be screened can be poured into the storage tank 4 for storage at one time. At this time, the synchronous starting motor 12 and the screening device body 2 are started. The screening device body 2 is started so that the screening device body 2 vibrates up and down, and the motor 12 starts to drive the fixed plate 11 and the sliding block 10 to rotate with the mounting shaft 13 as the center, and the sliding block 10 rotates with the mounting slot 9 during the rotation. In this process, the mounting block 8 is pushed with the fixed shaft 7 as the center. The center rotates back and forth in a fan shape, and in this process, the fixed shaft 7 is also driven to rotate back and forth. The rotation of the fixed shaft 7 synchronously drives the stirring rod 19, the scraper 20, the connecting rod 21, the anti-blocking rod 15, the mounting plate 14, and the rotating plate 16 to rotate back and forth synchronously. During the rotation of the rotating plate 16, it is dislocated with the through slot 18, so that the pharmaceutical intermediates in the storage tank 4 and the connecting pipe 3 can fall downward into the screening device body 2 through the through slot 18, thereby realizing the discharge of the pharmaceutical intermediates in the storage tank 4 without manual discharge, and during the discharge process, the cover 6 can be covered on the fixed pipe 5 to realize full sealing during the discharge and screening of the pharmaceutical intermediates, thereby preventing the pharmaceutical intermediates from floating out of the fixed pipe 5 during the discharge or screening process, optimizing the production environment, thereby avoiding the waste of raw materials, and being safer and more hygienic, thereby ensuring the quality of raw material production, and increasing the practicality of the screening device.
