[0056] Working or installation process:

[0057] Initial state: the scraper 25 is located at a side away from the second discharge chute 20 and the side wall of the scraper 25 is in contact with the side wall of the screening chamber 18; the baffle 27 is in contact with the side wall of the screening housing 14 and closes the sliding groove 23, the bolt is inserted into the insertion hole and the bolt is threadedly connected with the threaded hole 26, so that the baffle 27 is fixed to the side wall of the screening housing 14 and closes the sliding groove 23;

[0058] When screening is performed, the cover plate 15 is placed on the top wall of the screening housing 14, and the lock buckle 16 is used. The lock buckle 16 is engaged with the hook of the cover plate 15, so that the cover plate 15 is fixed on the top wall of the screening housing 14. The worker adds ingredients through the feed port on the top wall of the cover plate 15, and the ingredients pass through the feed port and fall onto the screen 29. The vibration motor 17 is started, and the vibration motor 17 causes the screening housing 14 to vibrate and screen. The screen 29 follows the screening housing 14 to vibrate and screen. The ingredients are located on the top wall of the screen 29 and vibrate and screen. A collection box with the opening facing upward is placed below the first discharge trough 19 and the second discharge trough 20, so that the ingredients that fall from the first discharge trough 19 and the second discharge trough 20 are collected.

[0059] According to the size of the sieve holes of the screen 29, the ingredients with a particle volume smaller than the sieve hole diameter of the screen 29 fall downward and fall onto the bottom wall of the screening chamber 18, and the ingredients with a particle volume larger than the sieve hole diameter of the screen 29 stay on the top wall of the screen 29. Since the screen 29 continues to vibrate, the ingredients that fall onto the bottom wall of the screening chamber 18 move along the extension direction of the screening chamber 18 until they fall into the second discharge chute 20; the ingredients located on the screen 29 move along the extension direction of the screen 29 until they fall into the first discharge chute 19, thereby completing the ingredient screening.

[0060] After the ingredients screening is completed, the vibration motor 17 is turned off, the lock 16 is opened, so that the lock 16 is disengaged from the hook of the cover plate 15, and the worker manually sweeps the ingredients remaining on the screen 29 into the first discharge chute 19; since some ingredients still remain on the bottom wall of the screening chamber 18, it is necessary to sweep the remaining ingredients into the second discharge chute 20; at this time, the bolt is rotated in the opposite direction to disengage the bolt from the threaded hole 26, the bolt is pulled out from the threaded hole 26, and the baffle 27 is rotated so that a part of the baffle 27 is moved out of the sliding groove 23, and the baffle 27 no longer closes the sliding groove 23, the drive motor 21 is started, and the output shaft of the drive motor 21 drives the threaded shaft 22 to rotate, the threaded shaft 22 is threadedly connected with the connecting plate 24 and drives the connecting plate 24 to move along the extension direction of the threaded shaft 22, and the connecting plate 24 drives the scraper 25 to move synchronously, and the scraper 25 pushes the ingredients remaining on the bottom wall of the screening chamber 18 until it is pushed into the second discharge chute 20;

[0061] When the scraper 25 moves to above the second discharge chute 20, the drive motor 21 starts in reverse, and the drive motor 21 drives the scraper 25 to move to the side away from the second discharge chute 20 and restores to the initial position; the baffle 27 is flipped over and the bolt is inserted into the insertion hole and the threaded hole 26 again, so that a part of the bolt is threadedly connected with the threaded hole 26, so that the baffle 27 is fixedly connected to the side wall of the screening housing 14 again and the sliding groove 23 is closed to prevent the ingredients from falling from the sliding groove 23 to the outside of the screening housing 14 during screening.
