[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figure 1-5 A stone mill grinding device for flour production includes a support frame 1, a fixed cover 2 fixedly connected to the inner side of the support frame 1, a lower grinding disc 3 rotatably connected to the lower part of the fixed cover 2, an upper grinding disc 4 fixedly connected to the inner side of the support frame 1 and above the lower grinding disc 3, a feed hopper 5 fixedly connected to one side of the top of the upper grinding disc 4, a sieve plate 6 slidably connected inside the feed hopper 5, grinding blocks 7 fixedly connected to the outside of the lower grinding disc 3, and a transmission assembly provided inside the fixed cover 2.
[0022] Specifically, the transmission assembly includes a motor 8 and a linkage unit. The motor 8 is fixedly connected to the top of the upper grinding disc 4 via a mounting plate. A rotating shaft 9 is fixedly connected to the top of the lower grinding disc 3 extending to the top of the upper grinding disc 4. The output end of the motor 8 is fixedly connected to the rotating shaft 9. The sieve plate 6 can move through the linkage unit. The linkage unit includes a first synchronous wheel 10, which is fixedly connected to the outside of the output end of the motor 8. A rotating rod 11 is rotatably connected to one side of the top of the upper grinding disc 4. A second synchronous wheel 12 is fixedly connected to the lower outside of the rotating rod 11. The first synchronous wheel 10 and the second synchronous wheel 12 are connected by a synchronous belt 13. A turntable 14 is fixedly connected to the top of the rotating rod 11. A sliding shaft 15 is fixedly connected to one side of the top of the turntable 14. Slide plates 16 are fixedly connected to both sides of the sieve plate 6 extending to the outside of the feed hopper 5. The slide plates 16 are slidably connected to the feed hopper 5. The sliding shaft 15 is slidably connected to the bottom side of the slide plate 16.
[0023] With the above technical solution, when flour milling is required, wheat is fed into the hopper 5 above the sieve plate 6. Then, the motor 8 is started. The output of the motor 8 drives the bottom rotating shaft 9 and the lower grinding disc 3 to rotate, and simultaneously drives the first synchronous wheel 10 to rotate. The first synchronous wheel 10 drives the second synchronous wheel 12 and the rotating rod 11 to rotate through the synchronous belt 13. The rotating rod 11 then drives the top turntable 14 to rotate, so that the turntable 14 drives the top sliding shaft 15 to slide inside the slide plate 16. This pushes the slide plate 16 and the sieve plate 6 to perform high-frequency reciprocating motion, thereby sieving the wheat raw material through the sieve plate 6, removing impurities such as straw and stones from the raw material, thus avoiding impurities from affecting the subsequent milling effect, and effectively improving the quality of flour. After the wheat is sieved, it falls through the first discharge port 17 between the upper grinding disc 4 and the lower grinding disc 3, and is then milled by the rotation of the sieve plate 14. The moving lower grinding disc 3, in conjunction with the upper grinding disc 4, grinds wheat raw materials. The flour ground between the upper and lower grinding discs 4 and 3 can continue to fall through the second feed port 18 in the grinding block 7 to the bottom of the fixed cover 2. As the lower grinding disc 3 rotates, it can drive the external grinding block 7 to rotate as well. The rotating grinding block 7, in conjunction with multiple sieve discs 19, performs secondary grinding of the flour, resulting in finer flour. This effectively improves the uniformity of flour particles and the taste of the flour. This device can sieve the wheat raw materials before grinding to remove impurities such as straw and stones, thereby avoiding impurities from affecting the subsequent grinding effect and effectively improving the quality of the flour. Furthermore, the primary grinding by the lower grinding disc 3 and the upper grinding disc 4, combined with the secondary grinding by the grinding block 7 and the sieve discs 19, improves the fineness of the flour, thus effectively improving the uniformity of flour particles and the taste of the flour.
[0024] Specifically, a first discharge port 17 is provided on one side of the inner side of the upper grinding disc 4. The bottom of the feed hopper 5 extends into the inner side of the upper grinding disc 4 and is fixedly connected to the first discharge port 17. A second discharge port 18 is provided inside the grinding block 7. A screen plate 19 is fixedly connected at equal intervals on the bottom side of the fixed cover 2 near the grinding block 7. A collection frame 20 is fixedly connected inside the support frame 1 and below the fixed cover 2. A discharge port 21 is fixedly connected to the bottom of the collection frame 20. A solenoid valve is provided inside the discharge port 21.
[0025] With the above technical solution, the flour that has undergone secondary grinding can fall into the collection box 20, and then the solenoid valve can be opened to discharge the flour, making it convenient for staff to collect.
[0026] When grinding flour, wheat is fed into the hopper 5 above the sieve plate 6. The motor 8 is then started. The output of the motor 8 drives the bottom rotating shaft 9 and the lower grinding disc 3 to rotate, simultaneously driving the first synchronous wheel 10 to rotate. The first synchronous wheel 10 drives the second synchronous wheel 12 and the rotating rod 11 to rotate via the synchronous belt 13. The rotating rod 11 then drives the top turntable 14 to rotate, causing the turntable 14 to drive the top sliding shaft 15 to slide inside the slide plate 16. This pushes the slide plate 16 and the sieve plate 6 to perform high-frequency reciprocating motion, thus sieving the wheat raw material through the sieve plate 6, removing impurities such as straw and stones, preventing impurities from affecting the subsequent grinding effect, and effectively improving flour quality. After sieving, the wheat falls through the first discharge port 17 between the upper grinding disc 4 and the lower grinding disc 3. The rotating lower grinding disc 3, in conjunction with the upper grinding disc 4, grinds the wheat raw material. The flour ground between the lower grinding disc 4 and the upper grinding disc 3 can continue to fall through the second feed port 18 in the grinding block 7 to the bottom of the fixed cover 2. As the lower grinding disc 3 rotates, it can drive the external grinding block 7 to rotate as well. The rotating grinding block 7, in conjunction with multiple sieve discs 19, can perform secondary grinding of the flour, thereby obtaining finer flour and effectively improving the uniformity of flour particles and the taste of the flour. This device can sieve the wheat raw materials before grinding to remove impurities such as straw and stones, thereby avoiding impurities from affecting the subsequent grinding effect and thus effectively improving the quality of the flour. The primary grinding by the lower grinding disc 3 and the upper grinding disc 4, combined with the secondary grinding by the grinding block 7 and the sieve disc 19, improves the fineness of the flour, thereby effectively improving the uniformity of flour particles and the taste of the flour. The flour that has undergone secondary grinding can fall into the collection frame 20, and then the solenoid valve can be opened to discharge the flour for easy collection by the staff.
