[0002] Microbial fertilizers, also known as biological fertilizers, inoculants or bacterial fertilizers, are a type of fertilizer centered around the life activities of microorganisms, enabling crops to obtain specific waste effects. During the production process of microbial fertilizers, fermenters are required to ferment the raw materials of microbial fertilizers.

[0003] There is a existing microbial fertilizer fermentation device (its authorization announcement number is: CN221397759U), which drives the stirring shaft to rotate continuously by starting the motor to stir the microbial fertilizer in the fermenter, making the microbial fertilizer in the fermenter evenly mixed; however, the stirring mechanism of this microbial fertilizer fermentation device has a relatively simple structure and low stirring efficiency, failing to achieve the effect of highly efficient stirring of the microbial fertilizer in the fermenter; therefore, we propose the present utility model to solve the above problems. Summary of the Utility Model

[0005] To achieve the above object, the present utility model adopts the following technical solutions:

A feed pipe is arranged on one side wall of the fixed cylinder. A discharge pipe is arranged at the bottom of the fermenter. A top frame is fixedly installed on the top side of the fixed cylinder. A motor is fixedly installed on the top side of the top frame. One end of a driving rod is fixedly installed on the output shaft of the motor, and the other end of the driving rod rotatably extends into the fixed cylinder. A conveying and stirring mechanism is arranged on the driving rod. A plurality of openings are formed in the fixed cylinder. A top groove is formed in the inner wall of the top side of the fermenter.

A second spiral conveying blade is fixedly installed on the bottom side of the rotating ring. A first sprocket is fixedly installed on the driving rod. A transmission mechanism for the first sprocket and the external gear ring is arranged on the convex block on the top side of the fermenter.

[0007] Preferably, the conveying and stirring mechanism includes a first spiral conveying blade and a stirring paddle. Two first spiral conveying blades and two stirring paddles are respectively fixedly installed at one end of the driving rod that rotatably extends into the fixed cylinder; the two stirring paddles stir the microbial fertilizer conveyed downward in the fixed cylinder.

[0008] Preferably, the two stirring paddles are located between the two first spiral conveyor blades, and the contact surfaces of the two first spiral conveyor blades are attached to the inner wall of the fixed cylinder; the microbial fertilizer in the fixed cylinder is conveyed downward by the two first spiral conveyor blades.

[0009] Preferably, the second spiral conveyor blade is rotatably sleeved on the fixed cylinder, the inner contact surface of the second spiral conveyor blade is attached to the outer wall of the fixed cylinder, and the outer contact surface of the second spiral conveyor blade is attached to the inner wall of the fermentation tank; the microbial fertilizer on the inner wall of the fermentation tank is conveyed upward by the rotation of the second spiral conveyor blade outside the fixed cylinder.

[0010] Preferably, the multiple openings on the fixed cylinder are distributed in a circumferential array, and the inside of the fermentation tank is communicated with the inside of the fixed cylinder through the multiple openings; it is convenient for the ascending microbial fertilizer to fall into the fixed cylinder through the multiple openings.

[0011] Preferably, the transmission mechanism includes a driven rod, a second sprocket, a gear and a chain.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] For this microbial fertilizer fermentation device, by starting the motor, the first sprocket on the driving rod is driven to rotate. Under the action of the transmission mechanism, the second spiral conveyor blade at the bottom side of the rotating ring is driven to rotate outside the fixed cylinder, so as to convey the microbial fertilizer on the inner wall of the fermentation tank upward. When the microbial fertilizer rises to the multiple openings of the fixed cylinder, the microbial fertilizer falls into the fixed cylinder. The microbial fertilizer in the fixed cylinder is conveyed downward by the two first spiral conveyor blades, and the two stirring paddles stir the microbial fertilizer conveyed downward in the fixed cylinder, thereby realizing the circulating flow of the microbial fertilizer between the inside of the fermentation tank and the inside of the fixed cylinder.

One end of a drive rod 7 is fixedly installed on the output shaft of the motor 6. The other end of the drive rod 7 rotatably extends into the fixed cylinder 2. A conveying and stirring mechanism is provided on the drive rod 7. A plurality of openings 10 are provided on the fixed cylinder 2. A top groove 11 is provided on the inner wall of the top side of the fermentation tank 1. A rotating ring 12 is rotatably installed in the top groove 11.

A first sprocket 15 is fixedly installed on the drive rod 7.

[0021] Furthermore, the conveying and stirring mechanism includes a first spiral conveyor blade 8 and a stirring paddle 9. Two first spiral conveyor blades 8 and two stirring paddles 9 are respectively fixedly installed at one end of the drive rod 7 that rotatably extends into the fixed cylinder 2; the two stirring paddles 9 stir the microbial fertilizer conveyed downward in the fixed cylinder 2.

[0022] Specifically, the two stirring paddles 9 are located between the two first spiral conveyor blades 8, and the contact surfaces of the two first spiral conveyor blades 8 are attached to the inner wall of the fixed cylinder 2; the two first spiral conveyor blades 8 are used to convey the microbial fertilizer in the fixed cylinder 2 downward.

[0023] Specifically, the second spiral conveyor blade 14 is rotatably sleeved on the fixed cylinder 2, the inner contact surface of the second spiral conveyor blade 14 is attached to the outer wall of the fixed cylinder 2, and the outer contact surface of the second spiral conveyor blade 14 is attached to the inner wall of the fermentation tank 1; by rotating the second spiral conveyor blade 14 outside the fixed cylinder 2, the microbial fertilizer on the inner wall of the fermentation tank 1 is conveyed upward.

[0024] Specifically, the multiple openings 10 on the fixed cylinder 2 are distributed in a circumferential array, and the inside of the fermentation tank 1 is connected to the inside of the fixed cylinder 2 through the multiple openings 10; it is convenient for the rising microbial fertilizer to fall into the fixed cylinder 2 through the multiple openings 10.

[0025] Furthermore, the transmission mechanism includes a driven rod 16, a second sprocket 17, a gear 18 and a chain 19.
