[0021] Each active component 44 comprises: A plurality of movable sleeves 441 are spaced apart and movably sleeved on the outer wall of the stirring rod 43; A plurality of levers 443 are connected to the outer wall of the movable sleeve 441 through a ring 442 and rotate on the outer wall of the movable sleeve 441 to move the raw materials; The connecting rod 444 is connected between two adjacent movable sleeves 441 and is used to push the movable sleeves 441 to slide on the outer wall of the stirring rod 43 .

[0022] The activity component 44 also includes: The extension sleeve 446 is sleeved on the outer wall of the stirring rod 43 and connected to the movable sleeve 441 on the side away from the rotating shaft 42 through two push rods 445; A spring 448 is mounted on the inner wall of the extension sleeve 446 and connected to the end of the stirring rod 43 to push the extension sleeve 446 away from the stirring rod 43; The sliding bead 447 is mounted on the extension sleeve 446 and fits inside the fermentation tank 1; A plurality of arc blocks 449 are installed on the inner wall of the fermentation tank 1 and fit with the sliding ball 447 to push the extension sleeve 446 to move on the outer wall of the stirring rod 43 .

[0023] Working principle: When the raw materials are fermented, all the raw materials are placed in the fermentation tank 1 through the cover plate 3 for fermentation. At this time, the controller controls the motor 41 to rotate, thereby driving the rotating shaft 42 to rotate, and driving the multiple stirring rods 43 connected in a circle on the outer wall to rotate, thereby stirring the raw materials placed in the fermentation tank 1 to avoid accumulation in the fermentation tank 1, and breaking the anaerobic area in the fermentation tank to promote the fermentation of microorganisms and increase the fermentation speed; At the same time, when the stirring rod 43 rotates, it drives the sliding ball 447 to contact the arc block 449 inside the fermentation tank 1, which will squeeze the sliding ball 447 to push the extension sleeve 446 to move, thereby pushing the push rod 445 to move, so as to push the movable sleeve 441 connected to it to move, thereby moving the ring 442 and the lever 443 installed on the movable sleeve 441, and at the same time, after breaking away from the contact with the arc block 449, the sliding ball 447 is reset, and under the push of the spring 448, the extension sleeve 446 is pushed to move, and the movable sleeve 441 is driven to move, so that the lever 443 can be moved back and forth to improve the stirring effect of the raw materials, and at the same time, the stirring effect can be further improved in combination with the rotatable lever 443.

[0024] See also Figure 1-9 On the basis of the above embodiment, in another embodiment of the present invention, an auxiliary stirring mechanism 5 is provided on the arc blocks 449 arranged at intervals on the circumference, for assisting in stirring the raw materials, and the auxiliary stirring mechanism 5 comprises: The groove 51 is provided on the arc block 449; The L-shaped rod 52 is hinged in the groove 51 and is used to assist in stirring the raw materials.

[0026] Working principle: Through the L-shaped rod 52 connected to the arc block 449, when the rotating stirring rod 43 rotates, it touches the L-shaped rod 52 in an interlaced manner to achieve the crushing of the raw materials, so as to promote the interlaced crushing of the raw materials; At the same time, when the sliding ball 447 moves to the arc block 449 and contacts the spring plate 53, it will be pushed by the spring 448 to push the L-shaped rod to deflect around its hinge point and deflect upward. When it deflects upward, it can contact the rotating lever 443 to promote the shifting of the lever 443, thereby achieving the shifting effect to promote the shifting effect of the raw material.

[0027] See also Figure 1-9 Based on the above embodiment, in another embodiment of the present invention, the enzyme adding mechanism 6 comprises: An enzyme storage chamber 65 is provided in the stirring rod 43 and is used for storing enzymes; A plurality of through holes 67 are provided at the bottom of the stirring rod 43 and communicated with the interior of the enzyme storage chamber 65 for releasing the enzyme; A plurality of through holes 66 are provided on the connecting rod 444, and the connecting rod 444 is in contact with the outer wall of the stirring rod 43.

[0028] The enzyme adding mechanism 6 also includes: A hollow cavity 61 is provided in the fermentation tank 1; A fixed shaft 62, fixedly connected to the bottom of the inner wall of the hollow cavity 61 of the fermentation tank 1; The bottom of the rotating shaft 42 is rotatably connected to the bottom of the fermentation tank 1, and a seal is set at the connection, and the inner wall of the rotating shaft 42 is hollow; The air bag 64 is mounted on the inner wall of the rotating shaft 42, and an air hole 68 is opened at the connection between the rotating shaft 42 and the stirring rod 43 for injecting gas and spraying out the enzyme; A plurality of arc-shaped protrusions 63 are connected to the outer wall of the fixed shaft 62 , and the arc-shaped protrusions 63 squeeze the airbag 64 to eject gas from the air hole 68 .

[0030] Working principle: when the stirring rod 43 rotates, when the sliding ball 447 contacts the arc block 449 and detaches from the arc block 449, the extension sleeve 446 moves on the stirring rod 43. At the same time, the movement of the connecting rod 444 will change the blocking of the second through hole 67. At this time, the second through hole 67 and the first through hole 66 move with each other and overlap, so that the enzyme stored in the enzyme storage chamber 65 falls along the second through hole 67 and the first through hole 66.

At this time, the inner wall of the airbag 64 will be driven to contact the arc-shaped protrusion 63 to squeeze the airbag at different positions, so that the gas inside it is sprayed into the enzyme storage chamber 65 along the air hole 68 to release the enzyme. At the same time, it is connected with the interior of the fermentation tank 1 through the air hole to realize internal gas circulation, thereby realizing the fermentation of the raw materials.
