According to the data of the sensor 14, the control board 4 automatically adjusts each device, and the air delivery pipe 8 starts to deliver air. The air is transmitted to the aeration pipe 21 and the aeration disc 15. The motor 12 drives the aeration pipe 21 and the stirring blade 16 to rotate at a constant speed, improving the aeration efficiency and uniformity. After the aerobic treatment is completed and cleaning and maintenance are required, first use the control board 4 to retract the electric telescopic rod 23 into the interior of the storage groove, and then raise the first electric lifting rod 17 and the second electric lifting rod 18.
