After the second screening box 4 screens the flour, the screened flour falls into the material holding box 18. By setting the positioning component 2, when the material holding box 18 is placed, the pull plate 25 is pulled to drive the slide rod 24 and the limit plate 26 to slide in the fixed cylinder 22, and the spring 27 is compressed. Then, the material holding box 18 is placed in the folding plate 21, the pull plate 25 is released, and the spring 27 is stretched to push the slide rod 24 and the limit plate 26 to slide in the fixed cylinder 22. One end of the rod 24 enters the clamping hole 28 on the side of the material box 18 to achieve the effect of positioning and fixing the material box 18. When the material box 18 needs to be taken out of the folding plate 21, the pull plate 25 is pulled to drive one end of the slide rod 24 to move out of the clamping hole 28 on the side of the material box 18, and the material box 18 can be moved out of the folding plate 21. By setting the positioning component 2, the placement position of the material box 18 can be positioned and fixed to avoid the screened flour from falling into the material box 18 when the placement position of the material box 18 is inaccurate or the position of the material box 18 is offset due to the working vibration of the device. By setting the guide hopper 23 at the lower end of the second screening box 4, it is convenient for the screened flour to fall into the material box 18;

[0032] By adopting the above technical solution, when the device is not in use, the cover plate 10 is rotated by the dial plate 15, and the fixed ear 13 at one end of the cover plate 10 is rotated on the fixed plate 9 through the pin shaft 14. After the cover plate 10 is rotated to the upper end of the feed hopper 5, the upper end of the feed hopper 5 can be sealed. When the feed hopper 5 needs to be used, the cover plate 10 is opened, and the support plate 16 at one end of the fixed plate 9 supports the cover plate 10. At the same time, a rubber pad 17 is arranged on the upper end of the support plate 16 to buffer the contact between the cover plate 10 and the support plate 16. By arranging the cover plate 10, the feed hopper 5 can be sealed and protected when the device is not in use, so as to prevent dust and other impurities from falling into the first screening box 7 through the feed hopper 5 when the device is not in use, thereby causing pollution to subsequent flour screening.

[0033] Specifically, a bearing rotating seat is provided between the pin shaft 14 and the fixing plate 9 , and the rubber pad 17 and the supporting plate 16 are bonded by glue.

[0034] By adopting the above technical solution, the pin shaft 14 can rotate on the fixing plate 9, and the rubber pad 17 is not easy to fall off due to the glue bonding.

[0035] When this embodiment is in use, by setting the cover plate 10, the cover plate 10 is rotated by the dial plate 15 when the device is not in use, and the fixed ear 13 at one end of the cover plate 10 is rotated on the fixed plate 9 through the pin shaft 14. After the cover plate 10 is rotated to the upper end of the feed hopper 5, the upper end of the feed hopper 5 can be sealed. When the feed hopper 5 needs to be used, the cover plate 10 is opened, and the support plate 16 at one end of the fixed plate 9 supports the cover plate 10. At the same time, a rubber pad 17 is set on the upper end of the support plate 16 to buffer the contact between the cover plate 10 and the support plate 16. By setting the cover plate 10, the feed hopper 5 can be sealed and protected when the device is not in use, so as to prevent dust and other impurities from falling into the first screening box 7 through the feed hopper 5 when the device is not in use, causing pollution to subsequent flour screening.

The working principle is that flour is added to the first screening box 7 through the feed hopper 5, and the driving mechanism 11 drives the spiral leaf mechanism 8 and the stirring plate mechanism 6 to rotate. After the flour is screened in the first screening box 7, it falls into the second screening box 4. After the second screening box 4 screens the flour, the screened flour falls into the material holding box 18.

[0037] The working principle and use process of the utility model are as follows: when the flour screening device dedicated to flour processing is used, the device is installed at a suitable position, flour is added to the first screening box 7 through the feed hopper 5, the driving mechanism 11 drives the spiral blade mechanism 8 and the stirring plate mechanism 6 to rotate, and the flour falls into the second screening box 4 after being screened in the first screening box 7. After the second screening box 4 screens the flour, the screened flour falls into the material holding box 18. By setting the positioning component 2, when the material holding box 18 is placed, the pull plate 25 is pulled to drive the slide The rod 24 and the limit plate 26 slide in the fixed tube 22, and the spring 27 is compressed. Then, the material box 18 is placed in the folding plate 21, and the pull plate 25 is released. The spring 27 stretches and pushes one end of the slide rod 24 into the clamping hole 28 on the side of the material box 18, so as to achieve the effect of positioning and fixing the material box 18. When the material box 18 needs to be taken out of the folding plate 21, the pull plate 25 is pulled to drive one end of the slide rod 24 to move out of the clamping hole 28 on the side of the material box 18, so that the material box 18 can be moved out of the folding plate 21. By setting The positioning assembly 2 can position and fix the material box 18 to prevent the screened flour from falling into the material box 18 when the material box 18 is not placed accurately or the device vibrates during operation, causing the position of the material box 18 to shift. A guide hopper 23 is provided at the lower end of the second screening box 4 to facilitate the screened flour to fall into the material box 18. The cover plate 10 is provided, and the cover plate 10 is rotated by the dial plate 15 when the device is not in use. The fixed ear 13 at one end of the cover plate 10 rotates on the fixed plate 9 through the pin shaft 14, and the cover After the plate 10 rotates to the upper end of the feed hopper 5, the upper end of the feed hopper 5 can be sealed. When the feed hopper 5 needs to be used, the cover plate 10 is opened, and the support plate 16 at one end of the fixed plate 9 supports the cover plate 10. At the same time, a rubber pad 17 is arranged on the upper end of the support plate 16 to buffer the contact between the cover plate 10 and the support plate 16. By arranging the cover plate 10, the feed hopper 5 can be sealed and protected when the device is not in use, so as to prevent dust and other impurities from falling into the first screening box 7 through the feed hopper 5 when the device is not in use, causing pollution to the subsequent flour screening.
