[0026] The flour is screened by the cooperation between the vibration mechanism 2 and the screening mechanism 4. During the screening process, the flour is stirred by the stirring mechanism 3 to prevent the screening mechanism 4 from being blocked.

[0027] like Figure 2 . Figure 3 As shown, the output end of the motor 1 21 is fixedly connected to the rotating rod 1 22, the rear part of the outer wall of the rotating rod 1 22 is connected to the transmission belt 23, the left part of the transmission belt 23 is connected to the rotating rod 2 24, the rear end of the rotating rod 24 is rotatably connected to the connecting plate at the top of the screening box 1, and the outer walls of the rotating rod 1 22 and the rotating rod 2 24 are fixedly connected to the incomplete gear 25.

[0028] By starting motor 1 21 , motor 1 21 drives rotating rod 1 22 to rotate, rotating rod 1 22 drives transmission belt 23 to rotate, and transmission belt 23 drives rotating rod 2 24 to rotate, thereby causing rotating rod 1 22 and rotating rod 2 24 to simultaneously drive the incomplete gear 25 to rotate.

[0029] like Figure 2-Figure 4 As shown, the outer wall of the incomplete gear 25 is meshed with a tooth plate 26, the outer wall of the tooth plate 26 is slidably connected to the top of the screening box 1, the inner wall of the tooth plate 26 is slidably connected to the outer wall of the limit block 15, and the bottom of the tooth plate 26 is fixedly connected to the top of the screening frame 27.

[0030] When the incomplete gear 25 rotates, the incomplete gear 25 on the right side engages with the tooth plate 26, causing the tooth plate 26 to move upward. At the same time, the outer wall of the limit block 15 slides on the inner wall of the tooth plate 26, and the limit block 15 limits and guides the tooth plate 26 to prevent the tooth plate 26 from deflecting. At the same time, the tooth plate 26 drives the screening frame 27 to move upward synchronously. When the incomplete gear 25 on the right side rotates to a place without teeth, the incomplete gear 25 on the left side engages with the tooth plate 26, causing the tooth plate 26 to move downward, thereby causing the tooth plate 26 to move up and down reciprocatingly, and the tooth plate 26 drives the screening frame 27 to move synchronously.

[0031] like Figure 2 、 Figure 3 As shown, the left and right ends of the screening frame 27 are fixedly connected with guide blocks 271, the outer wall of the guide block 271 is slidably connected to the inner wall of the screening box 1, the bottom of the screening frame 27 is fixedly connected with a connecting rod 28, the bottom end of the connecting rod 28 is fixedly connected with a screen 29, the outer wall of the screen 29 is slidably connected to the bottom of the inner cavity of the screening box 1, the left and right ends of the screen 29 are fixedly connected with a limit block 291, and the outer wall of the limit block 291 is slidably connected to the inner wall of the screening box 1.

[0032] When the screening frame 27 moves, it drives the guide block to slide synchronously on the inner wall of the screening box 1, so as to screen the flour in the screening frame 27. At the same time, the screen 1 29 is also continuously moved up and down under the drive of the screening frame 27. The screen 1 29 drives the limit block 291 to slide on the inner wall of the screening box 1. The limit block 291 guides the screen 1 29, so that the screen 1 29 moves more smoothly. The flour filtered by the screen 1 29 falls on the guide plate 14. Since the guide plate 14 has a certain slope, the flour falling on the guide plate 14 is discharged from the discharge port 12, thereby completing the screening.

[0033] like Figure 2 、 Figure 5 As shown, the output end of the second motor 31 is fixedly connected to a rotating shaft 32 , the left end of the rotating shaft 32 is rotatably connected to the left end of the inner cavity of the screening frame 27 , and the outer wall of the rotating shaft 32 is fixedly connected to a stirring rod 33 .

[0034] By starting the second motor 31, the shaft 32 is driven to rotate, and the shaft 32 drives the stirring rod 33 to rotate, and the stirring rod 33 stirs the flour in the screening frame 27 to prevent the flour from piling up, causing the second screen 41 to be blocked, affecting the screening efficiency, and playing the effect of preventing the second screen 41 from being blocked.

[0035] like Figure 2 、 Figure 5 and Figure 6As shown, a limiting rod 42 is inserted into the inner wall of the screen 2 41 , and the outer wall of the limiting rod 42 is movably connected to the bottom of the screening frame 27 . The right part of the limiting rod 42 is fixedly connected to a spring 43 , and the left end of the spring 43 is fixedly connected to the bottom of the screening frame 27 .

[0036] When the screen 2 41 needs to be replaced, the limit rod 42 is pulled to extend the spring 43 so that the outer wall of the limit rod 42 is no longer plugged into the inner wall of the screen 2 41. The screen 2 41 can then be removed for replacement or maintenance, which makes disassembly easy.

[0037] The working principle of the utility model is as follows: when in use, flour is poured into the screening box 1 from the feed port 11, and the flour falls into the screening frame 27. At the same time, the motor 1 21 is started, and the motor 1 21 drives the rotating rod 1 22 to rotate, and the rotating rod 1 22 drives the transmission belt 23 to rotate, and the transmission belt 23 drives the rotating rod 24 to rotate, thereby making the rotating rod 1 22 and the rotating rod 2 24 drive the incomplete gear 25 to rotate at the same time, so that the incomplete gear 25 on the right side is engaged with the tooth plate 26, so that the tooth plate 26 moves upward, and at the same time the outer wall of the limit block 15 slides on the inner wall of the tooth plate 26, The limit block 15 limits and guides the tooth plate 26 to prevent the tooth plate 26 from deflecting. At the same time, the tooth plate 26 drives the screening frame 27 to move upward synchronously. When the incomplete gear 25 on the right side rotates to a place without teeth, the incomplete gear 25 on the left side meshes with the tooth plate 26, causing the tooth plate 26 to move downward, thereby causing the tooth plate 26 to move up and down reciprocatingly. The tooth plate 26 drives the screening frame 27 to move synchronously, and the screening frame 27 drives the guide block to slide synchronously on the inner wall of the screening box 1, thereby screening the flour in the screening frame 27 and achieving a vibration effect. At the same time, the motor 231 is started to drive the rotating shaft 32 to rotate, so that the rotating shaft 32 drives the stirring rod 33 to rotate, and the stirring rod 33 stirs the flour in the screening frame 27 to prevent the flour from piling up, which causes the sieve 2 41 to be blocked and affects the screening efficiency, thereby preventing the sieve 2 41 from being blocked. The flour filtered by the sieve 2 41 falls onto the sieve 1 29, and the sieve 1 29 is also driven by the screening frame 27 to move up and down, and the sieve 1 29 drives the limit block 291 to slide on the inner wall of the screening box 1, and the limit block 291 is used to move the flour The screen 1 29 is guided to make the screen 1 29 move more smoothly. The flour filtered by the screen 1 29 falls on the guide plate 14. Since the guide plate 14 has a certain slope, the flour falling on the guide plate 14 is discharged from the discharge port 12. Subsequently, when the screen 2 41 needs to be replaced, the limit rod 42 is pulled to extend the spring 43 so that the outer wall of the limit rod 42 is no longer connected with the inner wall of the screen 2 41. Then the screen 2 41 can be removed for replacement or maintenance, which makes disassembly easy, thereby greatly improving the user experience.
