The bottom of the rotating rod 4 is connected to the surface of the inner cavity of the fermentation box 1 and is evenly provided with stirring rods 5. The inner wall of the fixed frame 2 is also fixedly provided with a supporting eave 6 for supporting the edge of the box cover 3. An opening 7 communicating with the inner cavity is opened on the outer side of the fixed frame 2. A first motor 8 for driving the box cover 3 to rotate in the fixed frame 2 is also fixedly connected to the outer side of the fermentation box 1. The rotating rods 4 are located on the outer side of the upper end of the box cover 2 and are fixedly sleeved with mutually meshing transmission gear discs 9. The upper end of the box cover 3 is fixedly connected with The second motor 10 drives the right rotating rod 4 to rotate, wherein a threaded pin 201 is provided through the outer thread of the fixed frame 2, and a ball 202 is movably embedded in the inner end of the threaded pin 201, and an annular groove 302 is arranged around the outer wall of the box cover 3, and the ball 202 is movably engaged with the annular groove 302, and the outer wall of the box cover 3 is also evenly provided with latch teeth 301, and the power end of the first motor 8 is fixedly connected to a driving gear 303 meshing with the latch teeth 301 on the outer wall of the box cover 3, and the switch panel 13 includes a switch group and a display screen, and the switch group includes switches for the first motor 8, the second motor 10 and the exhaust fan 11.

[0022] Based on the above structure, the device docks the box cover 3 with the supporting eaves 6 at the upper end of the fixed frame 2, and then rotates the threaded pin 201 to make the ball 202 at its inner end engage in the annular groove 302 on the outer side of the box cover 3, so that the box cover 3 can be relatively limited in the fixed frame 2, and when stirring and mixing, the first motor 8 and the second motor 10 are started by an external switch, and the second motor 10 drives the right rotating rod 4 to rotate and cooperates with the mutually meshing transmission gear disks 9, thereby realizing the synchronous rotation of the three groups of rotating rods 4, and the stirring rod 5 at the bottom of the rotating rod 4 is used to mix and stir the organic fertilizer in the fermentation box 1, so that the accumulated organic fertilizer can be fully heat-dissipated and fermented, and the driving gear 303 at the power end of the first motor 8 is meshed and engaged with the card teeth 301 on the outer side of the box cover 3, thereby driving the box cover 3 and the fixed frame 2 on the upper end of the fermentation box 1 to rotate, and then the rotating rod 4 rotates and stirs while also moving in a circle, thereby improving the relative thoroughness of the stirring.

When the temperature is too high, the exhaust fan 11 can be started by the switch to draw air through the filter net 401 at the upper end of the middle rotating rod 4 and filter out the dust. Then the air flow flows out through the air hole 12 at the bottom of the middle rotating rod 4, and then is sucked in through the air hole 12 at the bottom of the left rotating rod 4 together with the high-temperature gas inside. Finally, it is extracted through the connecting pipe 1101 in cooperation with the exhaust fan 11 to achieve heat dissipation of the high-temperature gas inside the fermentation box 1, thereby ensuring the appropriate temperature for fermentation.
