[0022] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0023] Refer to Figures 1-4, an embodiment provided by the present utility model, a lactic acid bacteria fermentation device for culturing fermented soybean meal, includes a tank body 1. At both ends above the tank body 1, there are fixedly connected cylinders 16. The extending ends of the cylinders 16 are fixedly connected with connecting plates 19. By starting the cylinders 16, the connecting plates 19 can be driven to perform lifting adjustment. In the middle above the connecting plate 19, there is fixedly connected a driving motor 18. The output end of the driving motor 18 penetrates into the tank body 1 and is provided with a rotating rod 17 inside. At the upper end inside the tank body 1, there is fixedly connected a fixed block 22. By starting the driving motor 18, the rotating rod 17 can be driven to rotate, thereby driving the stirring plates 2 at both ends to rotate, so as to uniformly mix the internal fermentation raw materials and improve the mixing effect;

[0024] At the lower end of the fixed block 22, there is fixedly connected a compression spring 25. The other end of the compression spring 25 is fixedly connected with a movable block 23, and the movable block 23 is movably connected to the rotating rod 17. At the bottom of the rotating rod 17, there is fixedly connected a connecting block 12. Inside the tank body 1, there is fixedly connected a temperature sensor 21. Through the temperature sensor 21, the temperature inside the tank body 1 can be monitored in real time. At both ends of the movable block 23 and the connecting block 12, there are fixedly connected fourth rotating shafts 24. On the fourth rotating shafts 24, there is rotatably connected a second connecting rod 28. The other end of the second connecting rod 28 is rotatably connected to a third rotating shaft 14. The other end of the third rotating shaft 14 is fixedly connected with the stirring plate 2. Starting the cylinder 16 drives the connecting plate 19 and the driving motor 18 to move upward. Then, the rotating rod 17 follows the driving motor 18 to move upward. During the movement of the rotating rod 17, due to the elastic force of the compression spring 25, the position of the movable block 23 remains basically unchanged, and the distance between the movable block 23 and the connecting block 12 decreases. Under the action of the second connecting rod 28, the stirring plates 2 on both sides of the rotating rod 17 move away from the rotating rod 17, so that the stirring plates 2 are in contact with the inner wall of the tank body 1. At this time, the driving motor 18 is turned on, and then the driving motor 18 can drive the rotating rod 17 to rotate, thereby driving the stirring plates 2 at both ends to rotate, realizing the cleaning function of the inner wall of the tank body 1;

[0025] At one end above the tank body 1, there is penetrated and provided a feed inlet 20. At the other end above the tank body 1, there is penetrated and provided an exhaust pipe 15. Through the feed inlet 20, the fermentation raw materials can be fed into the tank body 1, and at the same time, the exhaust pipe 15 can realize its exhaust function;

[0026] Outside the tank body 1, there is provided a heating jacket 13. At the bottom of the tank body 1, there is penetrated and provided a discharge port 7. At both ends of the tank body 1, there are fixedly connected mounting blocks 29. Inside the mounting blocks 29, there are opened chutes 11. Inside the chutes 11, there is slidably connected a slider 10. The outer end of the slider 10 is fixedly connected with a support frame 3. At the bottom of the support frame 3, there is fixedly connected a base 4. Through the mounting blocks 29, the support frames 3 and the base 4 at both ends, the tank body 1 can be stably supported to ensure the stability of the device during use;

[0027] At both ends of the bottom of the tank body 1, a second rotating shaft 9 is fixedly connected. A first connecting rod 8 is rotatably connected to the second rotating shaft 9. The other end of the first connecting rod 8 is rotatably connected to a first rotating shaft 6. At both upper ends of the base 4, a connecting seat 5 is fixedly connected. A limiting groove 26 is formed inside the connecting seat 5. The first rotating shaft 6 is slidably connected inside the limiting groove 26. And one end of the first rotating shaft 6 is fixedly connected with a damping spring 27. When the stirring assembly inside the tank body 1 works, it will generate certain vibrations. At this time, the tank body 1 drives the second rotating shafts 9 at both lower ends to move downward. Under the action of the first connecting rod 8, the first rotating shaft 6 can be driven to squeeze the damping spring 27. Under the action of the damping spring 27, the shock absorption and buffering effect of the device can be realized, improving the stability of the device during use and reducing the noise generated during its stirring. At the same time, the damping spring in this device is composed of a damper and a spring, which can have the function of buffering and shock absorption. And sliders are arranged at both ends of the first rotating shaft 6, which can correspond to the sliding grooves inside the limiting groove 26 to ensure its stability.

[0028] Working principle: When this device is in use, first, the raw materials to be fermented are sent into the interior of the tank body 1 through the upper feed port 20. Then, the outer heating jacket 13 is started to heat the fermenting raw materials inside. After heating to an appropriate temperature, the upper driving motor 18 is started, which can drive the rotating rod 17 to rotate. Under the action of the rotating rod 17, the stirring plates 2 at both ends can be driven to rotate, so as to stir and mix the fermenting raw materials inside, improving the efficiency of their mixed fermentation. At the same time, during the fermentation process, the internal temperature sensor 21 can monitor the temperature inside the tank body 1 in real time to ensure the suitability of the temperature. After fermentation is completed, it can be discharged through the bottom discharge port 7. After discharging, a certain amount of materials will adhere to the inner wall of the tank body 1. At this time, the air cylinder 16 is started to drive the connecting plate 19 and the driving motor 18 to move upward. Then, the rotating rod 17 follows the driving motor 18 to move upward. During the movement of the rotating rod 17, due to the elastic force of the compression spring 25, the position of the movable block 23 remains basically unchanged. The distance between the movable block 23 and the connecting block 12 decreases. Under the action of the second connecting rod 28, the stirring plates 2 on both sides of the rotating rod 17 move away from the rotating rod 17, so that the stirring plates 2 are in contact with the inner wall of the tank body 1. At this time, the driving motor 18 is turned on, and then the driving motor 18 can drive the rotating rod 17 to rotate, thereby driving the stirring plates 2 at both ends to rotate, realizing the cleaning effect on the inner wall of the tank body 1.

Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
