[0014] Working principle of the utility model: When the organic fertilizer fermentation device of the utility model is used, agricultural waste is added to the fermentation barrel through the feed port, and hot water is introduced through the hot water pipe to increase the initial temperature, so that the fermentation starts quickly. The stirring mechanism in the device drives the stirring paddle and the auger blade to rotate simultaneously through the stirring shaft. While the waste rotates with the stirring paddle, it can be axially mixed under the action of the auger blade to improve the stirring and mixing efficiency. At the same time, the scraper and rubber strip clean the inner wall of the fermentation barrel to prevent it from sticking to the wall. During the fermentation process, the temperature in the fermentation barrel is monitored in real time by the temperature detection probe and displayed in real time on the display. The controller controls the stirring motor to automatically start stirring according to the temperature, and uses the stirring mechanism for efficient stirring to balance the temperature in the entire fermentation barrel. According to the detected temperature, when the temperature is too high, the solenoid valve on the cold water pipe is started to open to cool the fermentation barrel. The hot water discharged from the coil is connected to the greenhouse to heat the greenhouse. At the same time, air can be introduced into the fermentation barrel through the air intake pipe to provide an aerobic environment for fermentation. Alternatively, the lid-opening motor can be activated as needed, and the meshing action of the active gear drives the rotation of the driven gear, which in turn drives the screw, causing the pull plate to move linearly along the screw, opening the top lid and replenishing the CO2 produced by fermentation in the fermentation barrel into the greenhouse. After fermentation is completed, the gate valve and feeder are opened, and the fermented and decomposed agricultural waste is discharged through the discharge port and applied to the greenhouse soil as needed. In addition, a temperature alarm is set to sound an alarm when the temperature in the fermentation barrel reaches a certain value. Humidity and pH monitoring probes are also installed in the fermentation barrel. The detected humidity and pH values ​​are transmitted to the controller and displayed on the display. When the humidity or pH deviates from the set value, the staff is reminded to add water to the fermentation barrel or adjust the acidity and alkalinity to maintain suitable fermentation conditions for the materials in the fermentation barrel, which is conducive to improving fermentation efficiency.

[0015] The beneficial effects of the utility model are as follows: the organic fertilizer fermentation device of the utility model can increase the fermentation speed of agricultural waste by controlling the fermentation temperature and efficient mixing and stirring, utilize the heat and CO2 of aerobic fermentation of agricultural waste to heat and replenish the greenhouse, promote the growth and development of crops in the greenhouse, and apply the fermentation products to the soil as crop manure, effectively and comprehensively utilize agricultural waste, reduce livestock and poultry manure pollution, and improve agricultural greenhouse productivity.
