[0002] The methods for treating livestock and poultry manure mainly include organic fertilizer fermentation, drying treatment, biological treatment, feed technology, and disinfection treatment. Among them, organic fertilizer fermentation is to use microorganisms to decompose organic matter in livestock and poultry manure through aerobic fermentation or anaerobic fermentation technology to generate biological organic fertilizer or biogas. The aerobic fermentation method is more commonly used. It uses aerobic microorganisms to ferment under aerobic conditions, produces less odor, is dry, and is easy to package and apply. In the existing technology, during the process of aerobic fermentation of livestock and poultry manure to produce organic fertilizer, the livestock and poultry manure needs to be ventilated to allow the livestock and poultry manure to contact with oxygen and provide oxygen for the work of the microorganisms. At the same time, during the ventilation process, the manure needs to be stirred by a stirring rod to allow the manure to fully contact with oxygen. However, when some fermentation devices for aerobic fermentation of livestock and poultry manure to produce organic fertilizer are used, a lot of manure accumulates in the fermentation cylinder. Due to the influence of manure accumulation, the contact between manure and oxygen is not sufficient. Utility Model Content

The pushing plates 44 are used to push the feces between the outer arc surface of the separating ring 41 and the inner arc surface of the fermentation cylinder 1 to move upward until they fall downward from the dropping hole 43. The feces come into contact with oxygen during the falling process. At the same time, the feces inside the separating ring 41 continuously enters between the outer arc surface of the separating ring 41 and the inner arc surface of the fermentation cylinder 1 from the feeding hole 42, continuously driving the feces to move to a high place and fall downward, avoiding the accumulation of feces resulting in an increase in the force required for stirring, reducing energy consumption, and ensuring sufficient contact between feces and oxygen.

During the fermentation process, external oxygen enters the fermentation cylinder 1 through the oxygen inlet pipe 2, and the original air in the fermentation cylinder 1 is discharged through the ventilation pipe 3, providing oxygen for the aerobic fermentation of livestock and poultry manure. At the same time, the motor 6 is started by the control switch 7, and the output shaft of the motor 6 drives the turntable 45 and the pushing plate 44 to rotate. The pushing plate 44 is used to push the manure between the outer arc surface of the separation ring 41 and the inner arc surface of the fermentation cylinder 1 to move upward until it falls downward from the drop hole 43. The manure comes into contact with oxygen during the falling process. At the same time, the manure inside the separation ring 41 continuously enters between the outer arc surface of the separation ring 41 and the inner arc surface of the fermentation cylinder 1 from the feed hole 42, continuously driving the manure to move to a high place and fall downward, avoiding the increase in the force required for stirring due to the accumulation of manure, reducing energy consumption, and ensuring sufficient contact between manure and oxygen.
