[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] (1) A sliding assembly and a gear assembly are provided in the fermentation tank, and a stirring assembly is also provided on one side of the gear assembly. The gear assembly drives the small ring to rotate in the material, and brings out part of the material through the groove. After the small ring tilts, the material falls down, and the large ring brings out part of the material through the storage trough. After leaving the liquid surface, the material falls down. In the process of the material falling down, the material is fully exposed to oxygen, which accelerates the fermentation efficiency. When the small ring and the large ring rotate in the fermentation tank, the material is stirred. The inclined rod is driven by the connecting vertical rod to stir the dead corner in the fermentation tank. When the small ring rotates with the driving motor as the axis, the material is stirred, and the small ring rotates on the large ring through the meshing of the small gear, thereby increasing the stirring effect of the material. When the small ring rotates with the driving motor as the axis, it drives the large ring to rotate, so that the conical gear ring and the umbrella gear ring are meshed, so that the whole set of stirring mechanism rotates around the inner wall of the fermentation tank, so that the stirring is more flexible and the stirring range is wider, so that the stirring of the material is more sufficient;

[0018] (2) When the connecting vertical rod drives the diagonal rod to rotate, the connecting vertical rod and the diagonal rod stir the materials at the corners below the fermentation tank, so that the materials in the dead corners inside the fermentation tank can also be fully stirred, thereby improving the reaction efficiency between the materials and oxygen. When the connecting vertical rod drives the diagonal rod to rotate, the top of the diagonal rod hits the elastic vertical plate at the bottom of the fermentation tank, causing the elastic vertical plate to vibrate. The stirring component drives the connecting disk to rotate through the connecting component. During this period, the connecting component also stirs the materials, thereby improving the reaction efficiency between the materials and oxygen. The connecting disk drives the horizontal long rod to rotate. While the horizontal long rod stirs the materials at the center of the bottom of the fermentation tank, it hits the elastic horizontal plate, causing the elastic horizontal plate to vibrate, generating shear force, impact force, etc. through vibration. These forces act on the foam to cause it to burst. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of transverse long rods 46 are fixedly connected to the outer side of the connecting disk 45. When the connecting disk 45 drives the transverse long rods 46 to rotate, they collide with the elastic transverse piece 42, causing the elastic transverse piece 42 to vibrate, and the bubbles in the material are defoamed by vibration. A plurality of air outlets 47 are provided above the connecting disk 45, and oxygen enters the connecting disk 45 through the connecting pipe 43, and then is discharged into the fermenter 1 from the air outlet 47.

[0041] A sealing cover for sealing the fermentation tank 1 is provided above the fermentation tank 1, and a material injection port, a pressure relief port, etc. are provided on the sealing cover.

[0042] The working principle and use process of the present invention are as follows: when in use, the material is poured into the fermentation tank 1 to ferment the material in the fermentation tank 1, the driving motor in the sliding block 311 drives the bevel gear 313 to rotate, the bevel gear 313 engages with the bevel gear 324, so that the bevel gear 324 rotates around the bevel gear 313, the bevel gear 324 drives the C-shaped frame 321 to rotate on one side of the C-shaped frame 321, the C-shaped frame 321 drives the small ring 331 to rotate around the driving motor in the sliding block 311 as the axis through the fixing plate 322, the small ring 331 drives the large ring 335 to rotate through the sliding groove 337, at this time the large ring 335 engages with the bevel gear ring 41 through the bevel gear ring 339, so that the large ring 335 rotates around the bevel gear ring 41, the bevel gear 324 drives the large gear 325 to rotate through the connecting rod, and the large ring 335 rotates. The gear 325 meshes with the pinion 326 to rotate, and the pinion 326 meshes with the teeth 333 to make the small ring 331 rotate in the sliding groove 337. At this time, the limiting short plate 338 slides in the annular groove 334, and the short rod 323 also slides in the annular groove 334. The short rod 323 ensures the stability of the small ring 331 during rotation. The conical gear ring 339 meshes with the umbrella-shaped gear ring 41 to make the large ring 335 rotate around the umbrella-shaped gear ring 41, thereby driving the entire stirring mechanism 3 to rotate around the inside of the fermentation tank 1. The sliding block 311 slides inside the rotating sliding cavity 12. The sliding block 311 drives the connecting vertical rod 34 and the inclined rod 35 to stir the materials at the corners inside the fermentation tank 1. When the inclined rod 35 moves, it hits the elastic vertical sheet 14, causing the elastic vertical sheet 14 to vibrate, and the bubbles in the material are defoamed by the vibration.

[0043] When the small ring 331 and the large ring 335 rotate in the fermentation tank 1, the small ring 331 brings out part of the material through the groove 332. When the small ring 331 is tilted and the opening direction of the groove 332 is downward, all the material falls out. When the large ring 335 rotates, part of the material is brought out through the storage tank 336. After the material in the storage tank 336 leaves the liquid surface, it starts to fall and repeatedly contacts with oxygen in this process, thereby improving the fermentation efficiency.

[0044] When the small ring 331 rotates, it drives the C-shaped block 361 to rotate. The C-shaped block 361 drives the vertical rod 364 to rotate in the fermenter 1 through the connecting block 363. The connecting block 363 drives the connecting plate 45 to rotate in the fermenter 1. The connecting plate 45 drives the horizontal long rod 46 to hit the elastic cross piece 42, so that the elastic cross piece 42 vibrates to eliminate bubbles in the material through vibration.

[0045] The stirring assembly 33 stirs the material inside the fermentation tank 1 during the rotation and revolution, and makes the connecting vertical rod 34 and the oblique rod 35 stir the dead corner inside the fermentation tank 1, so that the material can be better stirred and the material can be fermented better;

[0046] When the stirring component 33 rotates, it takes part of the material away from the liquid surface, and then makes the material fall by itself. During the falling process of the material, the falling material is fully contacted with oxygen, thereby increasing the efficiency of material fermentation.

[0047] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
