[0029] In one embodiment, a crushing shaft 5 is symmetrically rotatably connected inside the crushing chamber 2. A transmission gear 7 is installed at one end of the crushing shaft 5. A drive gear 8 is meshed between the transmission gears 7. One end of the drive gear 8 passes through one side of the fermentation box 1 and is connected to the output end of the first motor 9.

The crushing chamber 2 is designed to crush agricultural waste to facilitate faster fermentation in the future.

[0030] In one embodiment, a stirring rod 22 is rotatably connected to the middle position inside the fermentation chamber 16. One end of the stirring rod 22 passes through one side of the fermentation box 1 and is connected to the third motor 21.

[0031] In one embodiment, a heating chamber 17 is provided on the outside of the fermentation chamber 1 at the inner position of the surface of the fermentation chamber 1. Several sets of electric heating tubes 18 are installed inside the heating chamber 17. The electric heating tubes 18 are set to heat the fermentation chamber 16 to ensure that the fermentation chamber 16 is at the optimal fermentation temperature.

[0036] Working Principle: In actual use, personnel can add the agricultural waste to the fermentation chamber 1 through the feed pipe 4. The agricultural waste will fall into the crushing chamber 2 at the top. The operation of the first motor 9 drives the drive gear 8 to rotate, which in turn drives the transmission gear 7 to rotate. The transmission gear 7 drives the crushing shaft 5 on the surface to rotate at high speed. At this time, the multiple sets of crushing blades 6 on the surface of the high-speed rotating crushing shaft 5 can crush the agricultural waste, thus facilitating more thorough fermentation. After crushing, the agricultural waste can fall into the sterilization chamber 11 in the middle through the outer movement of the sealing plate 23. First, the agricultural waste can be sterilized by the irradiation of the ultraviolet sterilization lamp 10. Then, the ultraviolet sterilization lamp 10 is turned off, and ozone can be introduced into the gas supply rod 26 through the ozone pipe 25 by the external ozone generator. The ozone is then introduced from the gas supply rod 26 through the gas outlet 13 on the surface of the gas supply rod 26 and the auxiliary rod 27. The process involves discharging ozone, allowing it to reach agricultural waste in different locations. During ozone sterilization, the second motor 12 rotates the gas delivery rod 26 and auxiliary rod 27, agitating the agricultural waste and increasing its contact area with ozone, thus enhancing the overall sterilization effect and removing unwanted bacteria. The agricultural waste is then discharged into the fermentation chamber 16 below. Simultaneously, the necessary bacteria for fermentation, such as EM bacteria, yeast, actinomycetes, and cellulose-decomposing bacteria, can be added through the inoculum addition tube 14. The specific inoculum types can be adjusted according to requirements. After the inoculum is added, the rotation of the stirring rod 22 drives the internal stirring blades 20 to agitate the agricultural waste, ensuring it comes into full contact with the inoculum and heat, thereby improving the overall fermentation quality and facilitating better use. This enhances the practicality of the device, which boasts advantages such as good fermentation effect, effective sterilization of unwanted bacteria, and high practicality.
