Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 7 , the present utility model details the above technical solutions through the following embodiments:

[0028] A koji uniform mixer for Baijiu brewing, comprising: a bottom plate 1; a vertical plate 2 fixedly connected to the top of the bottom plate 1, a rotary frame 3 is arranged on one side of the vertical plate 2, a stirring barrel 4 is arranged inside the rotary frame 3, a barrel cover 5 is arranged on the top of the stirring barrel 4, a gear box 6 is fixedly connected to the bottom of the stirring barrel 4, and the bottom of the gear box 6 is fixedly connected to the rotary frame 3; a linkage mechanism 7 for controlling the flipping of the stirring barrel 4 is arranged on one side of the rotary frame 3 close to the vertical plate 2; a reverse rotation mechanism 8 for fully stirring the koji inside while the stirring barrel 4 is flipped is arranged inside the stirring barrel 4. After the user pours the koji into the inside of the stirring barrel 4 and closes the barrel cover 5, the rotary frame 3 is controlled to rotate by itself through the linkage mechanism 7. While the rotary frame 3 rotates by itself, it drives the stirring barrel 4 and the reverse rotation mechanism 8, so that while the stirring barrel 4 rotates by itself, the reverse rotation mechanism 8 inside stirs the koji, which can control the rotation of the stirring barrel 4 while the device stirs and mixes the koji inside the stirring barrel 4, avoiding the situation that a small amount of koji adheres to the inner edge of the stirring barrel 4. In the existing koji uniform mixer for wine brewing, a small amount of koji is easily adhered to the corners inside the mixing box, and the internal mixing components cannot stir and mix the koji at the corners in the mixing box, resulting in poor mixing effect of the koji.

[0029] Such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown in the figure, the linkage mechanism 7 includes: on one side of the rotating frame 3 close to the vertical plate 2, a first rotating shaft 9 is fixedly connected. One end of the first rotating shaft 9 far from the rotating frame 3 penetrates through the vertical plate 2 and extends to the outside of the vertical plate 2. The first rotating shaft 9 is rotatably connected to the vertical plate 2; a first bevel gear 10 is sleeved on the outer surface of the first rotating shaft 9 near the vertical plate 2. A connecting ring 11 is fixedly connected to one side of the first bevel gear 10 close to the vertical plate 2. The connecting ring 11 is fixedly connected to the vertical plate 2. A second bevel gear 12 is engaged with the bottom of the first bevel gear 10. A second rotating shaft 13 is fixedly connected to the center of the second bevel gear 12. A fixed block 14 is rotatably connected to the outer surface of the second rotating shaft 13. The fixed block 14 is fixedly connected to the rotating frame 3. A first synchronous pulley 15 is fixedly connected to the outer surface of the bottom of the second rotating shaft 13. A second synchronous pulley 16 is arranged on one side of the first synchronous pulley 15. The second synchronous pulley 16 is connected to the first synchronous pulley 15 through a first synchronous belt 17; a speed reduction mechanism 18 for controlling the slow rotation of the stirring barrel 4 is arranged at one end of the first rotating shaft 9 far from the rotating frame 3. The speed reduction mechanism 18 drives the first rotating shaft 9 to rotate. While the first rotating shaft 9 rotates, it drives the rotating frame 3. The rotating frame 3 drives the stirring barrel 4 to rotate through the cooperation of the gearbox 6 and the bucket cover 5. While the rotating frame 3 rotates, it also drives the second rotating shaft 13 through the fixed block 14. The second rotating shaft 13 drives the second bevel gear 12 to make a circular motion with the first bevel gear 10 as the center. While the second bevel gear 12 makes a circular motion, it also rotates by itself through the cooperation of the first bevel gear 10. While the second bevel gear 12 rotates, it drives the second rotating shaft 13. The second rotating shaft 13 drives the first synchronous pulley 15. The first synchronous pulley 15 drives the second synchronous pulley 16 through the first synchronous belt 17.

[0030] As Figure 6As shown in the figure, the reversing mechanism 8 includes: a hollow tube 19 is rotatably connected to the center of the stirring barrel 4. A stirring shaft 20 is arranged inside the hollow tube 19. The bottom end of the hollow tube 19 penetrates through the gearbox 6 and extends to the third bevel gear 21. The third bevel gear 21 is fixedly connected to the hollow tube 19. A fourth bevel gear 22 is meshed with one side of the third bevel gear 21. A third rotating shaft 23 is fixedly connected to the center of the fourth bevel gear 22. The end of the third rotating shaft 23 away from the fourth bevel gear 22 is rotatably connected to the gearbox 6. A fifth bevel gear 36 is meshed with the bottom of the fourth bevel gear 22. The fifth bevel gear 36 is fixed on the outer surface of the stirring shaft 20. Two groups of stirring blades 24 are arranged on the outer surfaces of the hollow tube 19 and the stirring shaft 20 located inside the stirring barrel 4. The stirring blades 24 are respectively fixedly connected to the hollow tube 19 and the stirring shaft 20. The bottom end of the stirring shaft 20 penetrates through the gearbox 6 and the rotating frame 3 and extends to the second synchronous wheel 16. The second synchronous wheel 16 is fixedly connected to the stirring shaft 20. The stirring shaft 20 is rotatably connected to the gearbox 6 and the rotating frame 3. When the second synchronous wheel 16 rotates, it drives the stirring shaft 20. The rotation of the stirring shaft 20 drives the fifth bevel gear 36. The fifth bevel gear 36 drives the fourth bevel gear 22. The fourth bevel gear 22 rotates through the cooperation of the third rotating shaft 23 and then drives the third bevel gear 21. The third bevel gear 21 drives the hollow tube 19, so that the stirring shaft 20 and the hollow tube 19 rotate in opposite directions. While the stirring shaft 20 and the hollow tube 19 rotate in opposite directions, they drive the stirring blades 24, so that the stirring blades 24 stir the koji inside the stirring barrel 4. The koji inside the stirring barrel 4 can be stirred and mixed by the principle of coaxial reverse rotation, improving the stirring effect and solving the problem that when the original koji uniform mixer for wine brewing stirs the koji by an ordinary stirring method, the koji moves with the stirring mechanism due to inertia, resulting in poor stirring effect.

[0031] As Figure 7 shown, the deceleration mechanism 18 includes: a third synchronous wheel 25 is fixedly connected to the outer surface of the end of the first rotating shaft 9 away from the rotating frame 3. A fourth synchronous wheel 26 is arranged at the bottom of the third synchronous wheel 25. The diameter of the fourth synchronous wheel 26 is smaller than that of the third synchronous wheel 25. The third synchronous wheel 25 and the fourth synchronous wheel 26 are connected by a second synchronous belt 27. A connecting frame 28 is fixedly connected to the vertical plate 2 near the fourth synchronous wheel 26. A motor 29 is fixedly connected to the side of the connecting frame 28 away from the vertical plate 2. An output end of the motor 29 is fixedly connected to a fourth rotating shaft 30. The end of the fourth rotating shaft 30 away from the motor 29 is fixedly connected to the center of the fourth synchronous wheel 26. When the motor 29 is started, the output end of the motor 29 drives the fourth rotating shaft 30. The fourth rotating shaft 30 drives the fourth synchronous wheel 26. The fourth synchronous wheel 26 drives the third synchronous wheel 25 to rotate slowly through the second synchronous belt 27. While the third synchronous wheel 25 rotates, it drives the first rotating shaft 9.

[0032] As Figure 1 andFigure 2 As shown in the figure, a screw rod 31 is rotatably connected to the center of the top of the bucket cover 5. The top end of the screw rod 31 penetrates through the rotating frame 3 and extends to the rotating handle 32. The rotating handle 32 is fixedly connected to the screw rod 31. The screw rod 31 is threadedly connected to the rotating frame 3. The user rotates the rotating handle 32, and the rotating handle 32 drives the screw rod 31 to rotate. While the screw rod 31 rotates, it moves towards the mixing bucket 4 through the cooperation of the rotating frame 3. While the screw rod 31 moves, it drives the bucket cover 5, so that the bucket cover 5 moves to the mixing bucket 4 for closing.

[0033] As Figure 4 shown in the figure, a sealing ring 33 adapted to the bucket cover 5 is provided near the bucket cover 5 of the mixing bucket 4. The sealing ring 33 is fixedly connected to the bucket cover 5. An outer surface of the sealing ring 33 near the bucket cover 5 is sleeved with a sealing ring 34, which improves the sealing performance at the closing part of the mixing bucket 4 and the bucket cover 5, and avoids leakage of the internal koji during the self-rotation of the mixing bucket 4.

[0034] As Figure 1 and Figure 2 shown in the figure, universal wheels 35 with braking functions are provided at the four corners of the bottom of the bottom plate 1. The universal wheels 35 are fixedly connected to the bottom plate 1, which is convenient for the user to move and fix the device.

[0035] Working principle: After the user pours the koji into the mixing bucket 4, rotate the rotating handle 32. The rotating handle 32 drives the screw rod 31 to rotate. While the screw rod 31 rotates, it moves towards the mixing bucket 4 through the cooperation of the rotating frame 3. While the screw rod 31 moves, it drives the bucket cover 5, so that the bucket cover 5 moves to the mixing bucket 4 for closing. Start the motor 29. The output end of the motor 29 drives the fourth rotating shaft 30. The fourth rotating shaft 30 drives the fourth synchronous pulley 26. The fourth synchronous pulley 26 drives the third synchronous pulley 25 to rotate slowly through the second synchronous belt 27. While the third synchronous pulley 25 rotates, it drives the first rotating shaft 9. While the first rotating shaft 9 rotates self, it drives the rotating frame 3. The rotating frame 3 drives the mixing bucket 4 to rotate self through the cooperation of the gear box 6 and the bucket cover 5. While the rotating frame 3 rotates self, it also drives the second rotating shaft 13 through the fixing block 14. The second rotating shaft 13 drives the second bevel gear 12 to revolve around the first bevel gear 10 as the center. While the second bevel gear 12 revolves, it also rotates self through the cooperation of the first bevel gear 10. While the second bevel gear 12 rotates self, it drives the second rotating shaft 13. The second rotating shaft 13 drives the first synchronous pulley 15. The first synchronous pulley 15 drives the second synchronous pulley 16 through the first synchronous belt 17. It can control the self-rotation of the mixing bucket 4 while the device stirs and mixes the koji inside the mixing bucket 4, avoiding the situation that a small amount of koji adheres to the inner edge of the mixing bucket 4. In the existing koji uniform mixing machine for wine brewing, a small amount of koji is easily adhered to the corners inside the mixing box, and the internal mixing components cannot stir and mix the koji at the corners of the mixing box, resulting in poor mixing effect of the koji.

[0036] While the second synchronous pulley 16 rotates on its own axis, it drives the stirring shaft 20. The rotation of the stirring shaft 20 drives the fifth bevel gear 36. The fifth bevel gear 36 drives the fourth bevel gear 22. The fourth bevel gear 22 rotates on its own axis through the cooperation of the third rotating shaft 23 and then drives the third bevel gear 21. The third bevel gear 21 drives the hollow tube 19, so that the stirring shaft 20 and the hollow tube 19 rotate in opposite directions. While the stirring shaft 20 and the hollow tube 19 rotate in opposite directions, they drive the stirring blades 24, so that the stirring blades 24 stir the koji inside the stirring barrel 4. The koji inside the stirring barrel 4 can be stirred and mixed by the principle of coaxial reverse rotation, improving the stirring effect and solving the problem that when the original koji uniform mixer for wine brewing stirs the koji by an ordinary stirring method, the koji moves with the stirring mechanism due to inertia, resulting in poor stirring effect.
