[0027] Example 1: Please refer to Figure 1-Figure 3 In the existing wheat grain screening device for flour production, unqualified wheat grains will remain on the screen during screening, making it inconvenient to observe the screening process. In order to solve this technical problem, this embodiment discloses the following technical content;

[0028] The front side of the box body 1 is rotatably connected to the front door 2, and the middle part of the front door 2 is fixedly connected to the viewing window 3, and the rear right end of the front door 2 is fixedly connected to the protrusion 4. The front right end of the box body 1 is provided with a storage slot 5, and the protrusion 4 is engaged with the storage slot 5;

[0029] When screening wheat grains, the screening situation inside the box body 1 can be observed through the viewing window 3. When something happens inside, a handle is fixedly connected to the middle of the right end of the front side of the front door 2. The handle is held and turned to open the front door 2 to process the situation inside the box body 1. After the processing is completed, the front door 2 is closed on the box body 1. When closed, the protrusion 4 is engaged with the storage slot 5.

[0030] Example 2: In the existing wheat grain screening device for flour production, unqualified wheat grains are left on the screen, which will cause the screen to be blocked, making it difficult to avoid blockage. Therefore, this embodiment adopts the following technical solutions, such as Figures 1-6 As shown;

[0031] The top of the box body 1 is fixedly connected with an anti-blocking device 6, which is composed of a feed box 601, a grid plate 602, a bracket 603, a first motor 604 and a stirring rod 605. The inner bottom end of the feed box 601 is fixedly connected with the grid plate 602, and the middle part of the outer end of the feed box 601 is fixedly connected with the bracket 603, and the left and right sides of the bottom end of the bracket 603 are respectively fixedly connected to the left and right ends of the middle part of the upper surface of the box body 1, the middle part of the top of the bracket 603 is fixedly connected with the first motor 604, and the output shaft of the first motor 604 is fixedly connected with the stirring rod 605, the inner top of the box body 1 is fixedly connected with a guide plate 7, and a through slot 8 is provided in the middle part of the lower end of the rear side of the box body 1, and the box body 1 is fixedly connected to the screening device body 9 at the lower middle part of the rear side, and the screening device body 9 is composed of a second motor 901, a gear disc 902, a fixed block 903, a movable gear ring 904 and a connecting rod 905. The output shaft of the second motor 901 is fixedly connected to the gear disc 902, and fixed blocks 903 are installed on both sides of the left and right sides of the gear disc 902. The left and right ends of the bottom end of the rear side of the box body 1 are fixedly connected to the fixed blocks 903, and the interior of the fixed blocks 903 is slidably connected to the movable gear ring 904. The middle part of the front side of the movable gear ring 904 is fixedly connected to the connecting rod 905 by bolts, and the front end of the connecting rod 905 is fixedly connected to the middle part of the rear side of the screening box 10.
