Microbial inoculant has been widely used in agricultural production process.

[0003] During the fermentation process of microbial inoculant, fermentation material needs to be added. During the growth and metabolism of effective viable bacteria in microbial inoculant, fermentation material is decomposed and various secondary metabolites such as extracellular enzymes are produced. With the progress of fermentation, fermentation material is decomposed, and viable bacteria in microbial inoculant are multiplied. After fermentation is completed, beneficial activity in fermentation product is collected to make organic fertilizer or microbial fertilizer and the like.

[0004] In the prior art, related fermentation devices are disclosed. For example, CN221544585U discloses a microbial inoculant fermentation device, which comprises a fermentation tank, a hollow shaft is rotatably connected to the upper wall of the fermentation tank, a plurality of stirring rods are fixedly connected to the side surface of the hollow shaft, a pair of scrapers are connected to the outer ends of the stirring rods, a sampling cylinder is communicated with the right wall of the fermentation tank, a piston is slidably connected in the sampling cylinder, a slide rod is slidably connected to the right wall of the sampling cylinder, the left end of the slide rod is fixedly connected to the piston, and a sampling pipe is communicated with the lower wall of the sampling cylinder.

[0040] Turnover part 5 is symmetrically provided with two groups, including mounting seat 51 fixed on support frame 1, turnover cylinder 52 fixedly connected with mounting seat 51 at the fixed end and inclined downward toward the front wall of horizontal fermentation tank 2, and fish eye joint 53 fixed on the telescopic end of turnover cylinder 52; a circular shaft 26 is fixed at the position close to the front wall of horizontal fermentation tank 2 at the end of horizontal fermentation tank 2, the eye part of fish eye joint 53 is penetrated by circular shaft 26, and reinforcing rib 27 is fixed on the inner end of circular shaft 26; of course, the front side of support frame 1 is provided with a space for horizontal fermentation tank 2 to turn over, in order to prevent support frame 1 from tilting during the turnover of horizontal fermentation tank 2, counterweight 11 is placed on the rear side of support frame 1.

[0041] In the embodiment, the stirring member 4 further comprises a blade member 48 located between two adjacent support members 44, the blade member 48 comprising a mounting ring 481 mounted on the stirring shaft 42 and fixedly connected with the stirring shaft 42, and a plurality of crushing blades 482 fixed on the outer wall of the mounting ring 481 and extending radially along the mounting ring 481; the outer ends of the crushing blades 482 are located between two adjacent stirring plates 45.

[0042] In the embodiment, a limiting plate 28 is fixed to the rear wall of the horizontal fermentation tank 2 near the top, and a vertical limiting pin 29 is arranged on the limiting plate 28; a limiting rod 12 is fixed to the rear end of the support frame 1, and the limiting pin 29 vertically downwardly penetrates the limiting plate 28 and the limiting rod 12 and is inserted with an open pin (not shown in the figure).

[0043] It should be noted that the air inlet pipe 22 is connected with an external oxygen supply device for conveying oxygen into the horizontal fermentation tank 2 to meet the needs of the growth and metabolism of the living bacteria in the microbial agent; the reduction motor 41 and the heating wire 31 are connected with an external power supply, and the overturning air cylinder 52 is connected with an external air source.

[0044] In use, the limiting pin 29 vertically downwardly penetrates the limiting plate 28 and the limiting rod 12, and an open pin is inserted at the bottom of the limiting pin 29 to prevent the limiting pin 29 from coming out, so that the top opening of the horizontal fermentation tank 2 remains vertically upward. It is not difficult to understand that the limiting plate 28 and the limiting rod 12 are both provided with through holes corresponding to the limiting pin 29 (not marked in the figure).

[0045] The tank cover 21 is opened, the fermentation material is added into the horizontal fermentation tank 2, the appropriate microbial agent is inoculated, and the appropriate amount of water is added to make the water content in the fermentation material reach about 50%. The tank cover 21 is closed, and the heating wire 31 and the reduction motor 41 are started. When the heating wire 31 works, heat is generated to heat the horizontal fermentation tank 2, so that the inside of the horizontal fermentation tank 2 has a certain temperature. After heating for a period of time, the heating wire 31 is turned off. In actual use, the working time of the heating wire 31 can be used to make the inside of the horizontal fermentation tank 2 reach the appropriate temperature, so as to provide suitable temperature for the growth and metabolism of the living bacteria in the microbial agent.

[0046] When the reduction motor 41 works, the stirring shaft 42 is driven to rotate, and the stirring shaft 42 drives the support member 44 and the blade member 48 to rotate. When the support member 44 rotates, the stirring plate 45 is driven to rotate through the support rod 442, and when the support rod 442 and the stirring plate 45 rotate, the materials in the horizontal fermentation tank 2 are stirred and mixed, so that the fermentation material and the microbial agent are fully contacted, which is beneficial to the subsequent fermentation and decomposition of the fermentation material. Moreover, through the continuous rotation and stirring of the stirring plate 45, the materials at the bottom of the horizontal fermentation tank 2 are continuously rolled up and down, so that the fermentation degree of the fermentation material at different positions is uniform, and the fermentation material at different positions can be fully fermented and decomposed.

[0047] During the rotation of the blade member 48, the breaking blade 482 contacts the material in the horizontal fermentation tank 2, and while playing a certain stirring role, the breaking blade 482 also produces a shearing action on the material in the horizontal fermentation tank 2, breaks the fermentation material gathered together, and helps the fermentation material to be fully fermented and decomposed.

[0048] In addition, during the fermentation process, the switch valve 24 on the air inlet pipe 22 and the air outlet pipe 23 is opened every certain period of time, and oxygen is transported into the horizontal fermentation tank 2 through the air inlet pipe 22 to ensure the normal growth and metabolism of the microorganisms in the horizontal fermentation tank 2. After the oxygen transportation is completed, the switch valve 24 on the air inlet pipe 22 and the air outlet pipe 23 is closed. Through the stirring action of the stirring plate 45, the supporting rod 442 and the breaking blade 482, the microorganism agent in the horizontal fermentation tank 2 can also be fully contacted with oxygen, and the normal growth and metabolism of the microorganism agent can be ensured.

[0049] After the fermentation is completed, the reduction motor 41 is stopped, the limit pin 29 is taken out, the extension end of the turnover air cylinder 52 is extended, the extension end of the fish eye joint 53 is extended and a pushing force is generated on the circular shaft 26, under the action of the pushing force, the top of the horizontal fermentation tank 2 is turned forward, after the top of the horizontal fermentation tank 2 is inclined downward by a certain angle, the fermentation product in the horizontal fermentation tank 2 is discharged from the horizontal fermentation tank 2, and the fermentation product can be collected by placing a container below. During this process, the reduction motor 41 is started, and the stirring plate 45 rotates counterclockwise (see the orientation of Figure 1 ), which is beneficial to the discharge of the fermentation product from the horizontal fermentation tank 2.

[0050] The foregoing description of specific exemplary embodiments of the present application is intended for purposes of illustration and example only. These descriptions are not intended to limit the application in any way, but to explain the principles of the application. It will be apparent to those skilled in the art that many changes can be made without departing from the principles of the application.
