[0002] Aerobic fermentation treatment of livestock and poultry manure is a comprehensive technology that integrates manure reduction, harmlessness and resource utilization. In the fermentation tank, the manure materials are fully oxygenated and in full contact with the mixed materials under the rotating and tossing action of the agitator, and the high-humidity waste gas generated during the fermentation process is discharged to ensure reasonable fermentation temperature, humidity and oxygen content. The agitator usually includes a shaft, and the shaft is equipped with stirring blades that rotate with the shaft. The livestock and poultry manure in the fermentation tank has a certain solid content.

[0023] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways other than those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 and Figure 2 As shown in the figure, the stirring structure for the fermentation device provided by the present invention includes a tubular shaft body 100 and a plurality of stirring components 200 installed on the tubular shaft body 100. The stirring components 200 are spaced apart along the axial direction of the tubular shaft body 100 and also spaced apart along the circumferential direction of the tubular shaft body 100.

[0026] Specifically, the stirring assembly 200 includes a first stirring blade 210 and a second stirring blade 220. The first stirring blade 210 is fixed to the tubular shaft 100 at a first end thereof, and the second stirring blade 220 is fixed to the second end thereof. When the tubular shaft 100 rotates, the first stirring blade 210 and the second stirring blade 220 stir the material in the tank to mix it evenly and allow the material to fully come into contact with the incorporated bacterial agent or air for fermentation.

[0027] Furthermore, the cross-section of the first stirring blade 210 is a quadrilateral structure, specifically a rhombus. One of the diagonals of the quadrilateral structure is perpendicular to the axial direction of the tubular shaft 100, and the other diagonal of the quadrilateral structure is parallel to the length direction of the tubular shaft 100. The utility model is applied to a horizontal fermentation tank, and the tubular shaft 100 is arranged in a horizontal direction. The material in the tank has a certain material level, and when the first stirring blade 210 rotates in the circumferential direction, the surface that contacts the material head-on is an inclined surface, which can not only effectively cut into the material through the V-shaped front end, but also enhance the stirring effect on the material through the inclined surface.

[0028] Preferably, the first stirring blade 210 is a hollow tubular structure, which can reduce weight and save raw materials. During manufacturing, the first end of the first stirring blade 210 is welded to the sleeve, and then the sleeve is assembled to the tubular shaft body 100.

[0029] In actual application, the number of stirring components 200 is determined according to the volume of the processed material and the capacity of the tank, for example Figure 3 As shown in FIG, six stirring assemblies 200 may be provided, and each stirring assembly 200 is distributed at an angle of 60° in the circumferential direction of the tubular shaft 100 to ensure dynamic balance during rotation.

[0030] The tubular shaft 100 is fixedly connected to a solid shaft 300 at both ends, supported on a bearing seat by the solid shaft 300, ensuring the main shaft strength of the stirring mechanism. One end of the solid shaft 300 also needs to be keyed to a coupling to achieve high torque transmission. The coupling is connected to the reducer and drive motor.

[0031] Typically, the solid shaft 300 is a stepped shaft with a groove at the end. The solid shaft 300 is inserted into the tubular shaft body 100 and then welded at the joint.

[0032] Preferably, the lengths of the first and second stirring blades 210, 220 are perpendicular to each other. The second stirring blade 220 agitates the material close to the inner wall of the tank, effectively preventing the material from adhering to the inner wall of the tank. Specifically, the second stirring blade 220 includes a first plate 221 that is parallel to the axis of the tubular shaft 100 and is fixedly connected to the second end of the first stirring blade 210 along its length.

[0033] Furthermore, the second stirring blade 220 also includes a second plate body 222, which is vertically fixed on one side surface of the first plate body 221. The wide side surface of the first plate body 221 is perpendicular to the length direction of the first stirring blade 210, and the wide side surface of the second plate body 222 is parallel to the length direction of the first stirring blade 210.

[0034] like Figure 4 As shown in the figure, a first groove 231 is provided on the second end surface of the first stirring blade 210, and a second groove 232 is vertically provided at the bottom of the first groove 231. The first plate 221 is embedded in the first groove 231, and the second plate 222 is embedded in the second groove 232 and welded.

[0035] Furthermore, the second stirring blade 220 also includes a baffle 233, which abuts against the other side surface of the first plate body 221 and is welded to the second end face of the first stirring blade 210, thereby firmly connecting the second stirring blade 220 to the first stirring blade 210 and simplifying installation. The second plate body 222 acts as a reinforcing rib, which can enhance the mechanical strength of the first plate body 221. Moreover, the second plate body 222 increases the connection area between the second stirring blade 220 and the first stirring blade 210, thereby improving the connection strength.
