Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all 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.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution: a fermentation device for feed production raw materials, including a support frame 1 and a fermentation tank 2. The fermentation tank 2 is fixedly installed inside the support frame 1, and a sealing cover 3 is installed on the top of the fermentation tank 2. A support cylinder 4 is rotatably connected inside the sealing cover 3 through a bearing. At one end of the support cylinder 4 located inside the fermentation tank 2, scraping rods 5 are symmetrically and fixedly connected, and the scraping rods 5 are cooperatively connected to the inner wall of the fermentation tank 2.

[0023] It should be noted that the scraping rod 5 is integrally in an L-shaped structure, and the bottom end of the scraping rod 5 is matched with the spherical end of the fermentation tank 2, so that the scraping rod 5 can scrape the materials on the inner wall of the fermentation tank 2 in all directions, avoiding the situation that the materials adhere to the inner wall of the fermentation tank 2 and are difficult to clean later. An exhaust pump for extracting the gas inside the fermentation tank 2 is also provided on the outer wall of the fermentation tank 2 to prevent potential safety hazards caused by the increase in the internal air pressure of the fermentation tank 2.

[0024] A filtrate plate 6 is fixedly connected between the two scraping rods 5, and the outer side of the filtrate plate 6 is in contact with the inner wall of the fermentation tank 2. Stirring shafts 7 are fixedly connected at equal intervals below the filtrate plate 6 on the side walls of the scraping rods 5, and the stirring shafts 7 on the side walls of the two scraping rods 5 are arranged in a cross manner. A communication groove is opened at the top of the filtrate plate 6, and a fixed cylinder 8 is fixedly connected inside the communication groove. A transmission shaft 14 is rotatably connected inside the sealing cover 3, the end of the transmission shaft 14 passes through the fixed cylinder 8, a spiral blade 15 is arranged on the outer side of the transmission shaft 14, and the spiral blade 15 is located inside the fixed cylinder 8.

[0025] It should be noted that when the utility model is in use, the sealing cover 3 is opened. After the sealing cover 3 is lifted, the scraping rod 5, the filtrate plate 6, the stirring shaft 7, the fixed cylinder 8, the transmission shaft 14 and the spiral blade 15 inside the fermentation tank 2 are lifted out accordingly. The feed raw materials to be fermented are placed inside the fermentation tank 2, and then the sealing cover 3 is connected to the fermentation tank 2. At this time, the feed raw materials are located below the filtrate plate 6 inside the fermentation tank 2. An instrument for detecting temperature and humidity and a heating component are installed inside the fermentation tank 2, and a corresponding controller is installed outside it, which can control the temperature change inside the fermentation tank 2. After fermenting for a period of time, when stirring is required, the control system set by the device controls the driving motor 11 to work, causing the driving gear 12 to rotate. Through the meshing connection between the driving gear 12 and the gear ring 10, the support cylinder 4 rotates. The rotation of the support cylinder 4 drives the two scraping rods 5 to rotate, scraping the inner wall of the fermentation tank 2. The rotation of the scraping rod 5 drives the filtrate plate 6 and the stirring shaft 7 on the side wall of the scraping rod 5 to rotate accordingly, enabling the stirring shaft 7 to stir the fermentation raw materials. After fermentation is completed, the driving motor 11 stops working, and the rotation motor 18 is controlled to work, causing the driving pulley 17 to rotate. Through the transmission connection between the driving pulley 17 and the driven pulley 16, the transmission shaft 14 rotates. Under the action of the spiral blade 15, the fermentation raw materials at the bottom end inside the fermentation tank 2 are lifted to the top end inside the fermentation tank 2 and guided to the surface of the filtrate plate 6 through the guide plate 9, so that the fermented liquid passes through the filtrate plate 6 and is filtered to the bottom end of the fermentation tank 2. Part of the impurities are mixed in the filtered liquid. By opening the control valve on the drain port 19, the liquid and a small amount of mixed impurities are discharged and collected through the drain port 19.

[0026] A gear ring 10 is fixedly connected to the outer side of one end of the transmission shaft 14 located outside the sealing cover 3. The top of the sealing cover 3 is fixedly connected with a motor seat, and a driving motor 11 is fixedly installed inside the motor seat. The end of the output shaft of the driving motor 11 is fixedly connected with a driving gear 12, and the driving gear 12 is meshed with the gear ring 10.

[0027] It should be noted that the driving motor 11 is controlled to work, causing the driving gear 12 to rotate. Through the meshing connection between the driving gear 12 and the gear ring 10, the support cylinder 4 rotates. The rotation of the support cylinder 4 drives the two scraping rods 5 to rotate, scraping and stirring the inner wall of the fermentation tank 2, integrating fermentation and stirring in the device and improving the production efficiency of the feed.

[0028] An L-shaped fixing plate 13 is fixedly connected to the top of the sealing cover 3. The transmission shaft 14 is rotatably connected inside the L-shaped fixing plate 13. A driven pulley 16 is fixedly connected to the top of the transmission shaft 14. A rotation motor 18 is fixedly connected to one end of the top of the sealing cover 3 away from the driving motor 11. The end of the output shaft of the rotation motor 18 is fixedly connected with a driving pulley 17, and the driving pulley 17 and the driven pulley 16 are connected by a belt transmission.

[0029] It should be noted that by controlling the operation of the rotating motor 18 to rotate the driving pulley 17, the transmission connection between the driving pulley 17 and the driven pulley 16 causes the transmission shaft 14 to rotate. Under the action of the spiral blade 15, the fermentation raw materials at the bottom end inside the fermentation tank 2 are lifted to the top end inside the fermentation tank 2 and guided to the surface of the filtrate plate 6 through the guide plate 9, so that the fermented liquid is filtered to the bottom end of the fermentation tank 2 through the filtrate plate 6, and the feed accumulates on the filtrate plate 6.

[0030] The bottom end of the fermentation tank 2 is of a hemispherical structure.

[0031] It should be noted that the bottom end of the fermentation tank 2 is set to a hemispherical structure, enabling the internal materials and liquid to be quickly discharged under the action of gravity, avoiding the situation of raw materials accumulating at the four corners.

[0032] A liquid discharge port 19 is provided at the center of the bottom of the fermentation tank 2, and a control valve is provided outside the liquid discharge port 19.

[0033] It should be noted that the setting of the liquid discharge port 19 facilitates the quick discharge of the materials and liquid with filter residues inside the fermentation tank 2.

[0034] A vertical observation window 20 is provided on the outside of the fermentation tank 2.

[0035] It should be noted that the setting of the observation window 20 facilitates observing the fermentation situation of the internal raw materials, so as to timely understand the fermentation degree of the raw materials.

[0036] Interlayers are provided inside both the fermentation tank 2 and the sealing cover 3, and heat-insulating cotton is filled in the interlayers.

[0037] It should be noted that the setting of the heat-insulating cotton ensures the heat-insulating effect of the fermentation tank 2, is conducive to maintaining a constant temperature inside the fermentation tank 2, and thus realizes better fermentation.

[0038] A guide plate 9 is fixedly connected to the outside of the top end of the fixed cylinder 8, and the guide plate 9 is of an overall conical structure.

[0039] It should be noted that the setting of the guide plate 9 at the top end of the fixed cylinder 8 facilitates the scattered distribution of the lifted materials around the top of the filtrate plate 6, ensuring the dispersion of the materials and being conducive to better filtering out the liquid.
