[0039] The first bevel gear 403 is connected to the output end of the drive motor 402 via a rotating shaft and a coupling. The first bevel gear 403 is used to provide rotational thrust to the second bevel gear 404.

[0040] The second bevel gear 404 is rotatably mounted inside the transmission box 401 via a shaft, and the second bevel gear 404 is used to provide rotational thrust to the third bevel gear 405.

[0041] The third bevel gear 405 is rotatably mounted on the inner side of the transmission box 401 and meshes with the outer wall of the second bevel gear 404. The third bevel gear 405 is used to drive the first stirring rod 406 to rotate synchronously.

[0042] The stirring unit includes a first stirring rod 406, a fixed rod 407, and a second stirring rod 408;

[0043] The first stirring rod 406 is fixed to the bottom end of the third bevel gear 405 and extends through the transmission box 401 into the interior of the fermentation tank 1. The first stirring rod 406 is used to stir the raw materials inside the fermentation tank 1 clockwise.

[0044] The fixing rod 407 is fixed to the bottom of the first bevel gear 403 and passes through the first stirring rod 406 to the outside of the first stirring rod 406. The fixing rod 407 is used to synchronously drive the second stirring rod 408 to rotate.

[0049] In this embodiment: the raw materials to be fermented are fed into the fermentation tank 1 through the feed port 2. The drive motor 402 is started by turning on the power supply connected to it. The working drive motor 402 drives the first bevel gear 403 connected to the output end to rotate counterclockwise. The counterclockwise rotating first bevel gear 403 provides rotational thrust to the second bevel gear 404. The rotating second bevel gear 404 transmits the thrust to the third bevel gear 405. Since the first bevel gear 403 and the third bevel gear 405 are symmetrically distributed vertically, and the second bevel gear 404 is in a vertical position, the third bevel gear 405, which is subjected to force, will rotate clockwise. The clockwise rotating third bevel gear 405 synchronously drives the first stirring rod 406 to rotate clockwise. The clockwise rotating first stirring rod 406 exerts force on the inside of the fermentation tank 1. The fermentation raw materials are stirred clockwise, and at the same time, the rotation of the first bevel gear 403 will synchronously drive the fixed rod 407 at the bottom to rotate, causing the fixed rod 407 to rotate counterclockwise. The counterclockwise rotation of the fixed rod 407 synchronously drives the second stirring rod 408 to rotate, causing the second stirring rod 408 to rotate counterclockwise over the raw materials inside the fermentation tank 1. Through the clockwise and counterclockwise stirring of the first stirring rod 406 and the second stirring rod 408, the raw materials inside the fermentation tank 1 are fully mixed. At the same time, when the first stirring rod 406 and the second stirring rod 408 rotate clockwise and counterclockwise, the guide ball fixed on the outer wall of the second stirring rod 408 will also move along the inner guide groove of the first stirring rod 406. Through the inclined annular guide groove 410, the second stirring rod 408 moves up and down during rotation, increasing the stirring range and further improving the stirring efficiency.

[0050] It should be noted that the protruding pin 411 is used to ensure the stable transmission between the fixed rod 407 and the second stirring rod 408.

[0051] Please refer to this carefully. Figures 1-4 The transmission box 401 has a rotating groove formed inside for the first stirring rod 406 to rotate. The inner side of the first stirring rod 406 has a rotating space for the fixed rod 407 to rotate. The first bevel gear 403 and the third bevel gear 405 are symmetrically distributed inside the transmission box 401. The outer walls of the first bevel gear 403 and the third bevel gear 405 mesh with the outer wall of the second bevel gear 404. The outer wall of the transmission box 401 is generally U-shaped. The outer wall of the discharge pipe 3 is equipped with a valve to control the discharge of raw materials.

[0052] In this embodiment: With this structure, after the raw materials have been stirred, mixed, and fermented, the valve on the discharge pipe 3 is opened, allowing the fermented raw materials to be discharged through the discharge pipe 3. The first bevel gear 403 and the third bevel gear 405, distributed vertically, provide rotational power to the second bevel gear 404, driving the third bevel gear 405 to rotate. The rotation direction of the third bevel gear 405 is opposite to that of the first bevel gear 403.
