[0038] Initially, the base 1 is provided with a collecting frame below the flow guide surface, the rotating joint 81 is connected with a water supply pipe, the electromagnetic valve 42 is closed, the staff opens the sealing cover 41 on the mixing tank 4 from the through opening of the protective shell 2, then the staff pours the bean dregs and auxiliary materials into the mixing tank 4, the staff stops pouring the bean dregs and auxiliary materials when the bean dregs and auxiliary materials reach one fourth of the height of the mixing tank 4, then the staff re-closes the sealing cover 41, and then the staff starts the driving motor 66 and the overturning motor 61, the rotating shaft of the driving motor 66 drives the stirring frame 64 to rotate, the stirring frame 64 rotates to stir the bean dregs and auxiliary materials below the mixing tank 4 through the paddle, so that the bean dregs and auxiliary materials are mixed, and the stirring frame 64 rotates to drive the dispersing frame 84 to rotate; After a period of stirring, the bean dregs and auxiliary materials are preliminarily mixed, the output shaft of the overturning motor 61 drives the driving gear 63 to rotate, the driving gear 63 drives the overturning gear 62 to rotate, the overturning gear 62 drives the rotating frame 3 to rotate, the rotating frame 3 drives the mixing tank 4, the sealing cover 41 and the electromagnetic valve 42 to rotate, the mixing tank 4 drives the stirring frame 64, the motor support 65, the driving motor 66, the spraying frame 82, the dispersing frame 84, the moving frame 85 and the intercepting net 86 to rotate, and the mixing tank 4 drives the bean dregs and auxiliary materials in the mixing tank 4 to rotate upward, and the spraying frame 82 drives one end of the rotating joint 81 to rotate; When the mixing tank 4 rotates more than 90 degrees, the dispersing frame 84, the moving frame 85 and the intercepting net 86 will slide downward as a whole under the action of gravity, and the soybean meal and the auxiliary materials rotating to the upper part will fall downward under the action of gravity, and the soybean meal and the auxiliary materials falling downward will pass through the moving frame 85, the intercepting net 86 and the dispersing frame 84, and when the mixing tank 4 rotates more than 180 degrees, the soybean meal and the auxiliary materials located above the mixing tank 4 will all fall to the lower part of the mixing tank 4, and the continuous rotation of the mixing tank 4 will drive the sealing cover 41, the electromagnetic valve 42, the stirring frame 64, the motor support 65, the driving motor 66, the spraying frame 82, the dispersing frame 84, the moving frame 85 and the intercepting net 86 to rotate, and at the same time, the rotation of the mixing tank 4 will drive the soybean meal and the auxiliary materials located below to rotate upward, and when the mixing tank 4 rotates more than 270 degrees, the dispersing frame 84, the moving frame 85 and the intercepting net 86 will slide downward under the action of gravity, and the soybean meal and the auxiliary materials will also fall downward under the action of gravity, and the soybean meal and the auxiliary materials falling downward will pass through the moving frame 85, the intercepting net 86 and the dispersing frame 84, and then the soybean meal and the auxiliary materials will fall to the lower part of the mixing tank 4, and then the mixing tank 4 will continuously bring the soybean meal and the auxiliary materials to the upper part, and the soybean meal and the auxiliary materials will repeatedly pass through the dispersing assembly and fall to the lower part under the action of gravity, so that the upper and lower soybean meal and auxiliary materials can be continuously turned over and reversed, and the accumulation of the soybean meal and the auxiliary materials in the dead angle of the mixing tank 4 can be reduced; At the same time, the continuous rotation of the stirring frame 64 can also continuously stir the materials, so that the soybean meal and the auxiliary materials can be more fully mixed; the water conveying pipe will intermittently inject the mixture of water and fermentation bacteria into the rotating joint 81 and the spraying frame 82, when the mixture is injected into the rotating joint 81 and the spraying frame 82, the mixture sprayed from the spraying holes on both sides of the spraying frame 82 will contact the soybean meal and the auxiliary materials, and then the mixing tank 4 will continuously bring the soybean meal and the auxiliary materials to the upper part, and then the soybean meal and the auxiliary materials will fall from the upper part, and the soybean meal and the auxiliary materials will contact the mixture sprayed from the spraying frame 82 in the process of falling downward, so that the soybean meal and the auxiliary materials can be more uniformly contacted with the mixture, and part of the soybean meal and the auxiliary materials contacted with the mixture will be absorbed and caked, and the caked soybean meal will be intercepted when passing through the intercepting net 86, and the rotation of the dispersing frame 84 will break the soybean meal cake stopped on the intercepting net 86, so that the soybean meal, the auxiliary materials and the mixture can be more uniformly mixed; After the mixed solution is continuously injected for a period of time, the mixed solution is then stopped from being supplied, and after the soybean meal, the auxiliary materials, and the mixed solution are fully mixed by the rotation of the mixing tank 4 and the rotation of the stirring frame 64, the mixed solution is again injected into the mixing tank 4 through the rotating joint 81 and the spraying frame 82, and this cycle is repeated several times. After the soybean meal, the auxiliary materials, and the mixed solution are fully mixed by the small amount of multiple injections of the mixed solution into the mixing tank 4, the staff member turns off the driving motor 66 and the overturning motor 61, and then the staff member starts the electromagnetic valve 42. The opening of the electromagnetic valve 42 allows the mixed soybean meal in the mixing tank 4 to flow out of the mixing tank 4 under the action of gravity, and then the mixed soybean meal falls onto the guide surface of the base 1. The mixed soybean meal flows along the guide surface of the base 1 to the collection frame, and finally the staff member closes the electromagnetic valve 42.

[0039] Example 2: Based on Example 1, as shown in Figures 10-11 The blocking mechanism is provided on the spraying frame 82 and includes two guide plates 91 welded to the base 1 and having guide grooves, a sealing plate 92 slidably connected in the spraying frame 82 and used to block the spraying holes on the spraying frame 82, and two driving rods 93 welded to the sealing plate 92 and slidably connected with the spraying frame 82 and the guide grooves of the two guide plates 91.

[0040] Initially, the sealing plate 92 blocks the spraying holes above the spraying frame 82. The rotation of the rotating frame 3, the mixing tank 4, and the spraying frame 82 drives the sealing plate 92 and the driving rods 93 to rotate. After the mixing tank 4 is rotated to 90 degrees, the rotating frame 3, the mixing tank 4, and the spraying frame 82 continue to drive the sealing plate 92 and the driving rods 93 to rotate. The continued rotation of the driving rods 93 causes them to be squeezed along the guide grooves of the guide plates 91, which causes the driving rods 93 to move away from the rotating frame 3. The movement of the driving rods 93 drives the sealing plate 92 to move away from the rotating frame 3, so that the sealing plate 92 no longer blocks the spraying holes above the spraying frame 82. The sealing plate 92 blocks the spraying holes below the spraying frame 82. After the mixing tank 4 is rotated to 180 degrees, the blocked spraying holes of the spraying frame 82 are rotated to the top, which prevents the soybean meal and the auxiliary materials from entering the spraying frame 82, so that the mixed solution can be more uniformly sprayed, and the mixing of the soybean meal, the auxiliary materials, and the mixed solution is more uniform. Then, this cycle is repeated.

[0041] Example 3: Based on Example 2, as shown in Figures 12-14As shown, a shaking mechanism is also included for shaking the intercepting net 86, which is arranged on the spray rack 82. The shaking mechanism includes: a guide rack 101 and a guide rack 102 welded on the spray rack 82, and the guide rack 101 and the guide rack 102 are respectively provided with a number of inclined surfaces; four contact rods 103 welded on the breaking rack 84, and the four contact rods 103 are in contact with the guide rack 101 and the guide rack 102 respectively; four fixed rotating racks 104 welded on the stirring rack 64, and the four fixed rotating racks 104 are divided into two groups, and the two groups of fixed rotating racks 104 are respectively on both sides of the spray rack 82.

[0042] The rotation of the scattering frame 84 will drive the contact rod 103 to rotate, and the rotation of the stirring frame 64 will drive the fixed rotating frame 104 to rotate. The rotation of the contact rod 103 will be squeezed by the inclined surfaces of the guide frame 101 and the guide frame 102, so that the contact rod 103 moves up and down along the inclined surfaces of the guide frame 101 and the guide frame 102. The up and down movement of the contact rod 103 will drive the scattering frame 84 to move up and down. The up and down movement of the scattering frame 84 will drive the moving frame 85 and the intercepting net 86 to move up and down. The up and down movement of the intercepting net 86 will drive the soybean meal and auxiliary materials on the intercepting net 86 to move up and down. When the soybean meal and auxiliary materials move up and down, the rotating fixed rotating frame 104 will move the soybean meal and auxiliary materials up and down to scatter them. At the same time, the soybean meal and auxiliary materials on the intercepting net 86 quickly fall to the bottom of the mixing tank 4, thereby making it possible to more fully scatter the soybean meal and auxiliary materials, thereby further improving the uniformity of mixing the soybean meal, auxiliary materials and mixed liquid.

[0043] Example 4: Based on Example 3, Figure 6 As shown, the mixing tank 4 further includes: two scraping rods 111 welded to the stirring frame 64 , and two scraping frames 112 welded to the stirring frame 64 . The two scraping rods 111 and the two scraping frames 112 are in contact with the side wall of the mixing tank 4 .

[0044] The rotation of the stirring frame 64 drives the scraper rod 111 and the scraper rack 112 to rotate, and the rotation of the scraper rod 111 and the scraper rack 112 will scrape off the soybean meal and auxiliary materials on the side wall of the mixing tank 4, thereby making the soybean meal and auxiliary materials mixed more fully and evenly.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
