Stirring device for sludge aerobic composting

The utility model relates to the technical field of stirring and mixing equipment, and discloses a stirring device for sludge aerobic composting, which comprises a main box body, a support fixedly arranged at the bottom of the main box body, and a stirring mechanism arranged in the main box body, and is characterized in that a discharge hole is formed in the middle of the bottom of the main box body; a flow guide plate is fixedly connected to one position of the discharge port, and the stirring mechanism comprises a rotating mechanism arranged above the flow guide plate. By adjusting a second spring fixedly connected to a pin and a stirring blade in the vibration mechanism, when the stirring blade rotates and is adjusted, the second spring rotates along with the stirring blade, so that torque force is generated, and when centrifugal force disappears, a first spring resets to pull a sliding rod to reset, so that the stirring blade is rotated and adjusted; therefore, the torque force of the second spring can be
