[0002] Biofertilizer is a product that contains both the nutrients needed by crops and microorganisms. It is a combination of biological, organic and inorganic substances. It can replace chemical fertilizers and provide various nutrients required for the growth and development of crops. In the production of microbial fertilizers, microbial fermentation equipment is required to ferment the fertilizer raw materials.

[0003] A prior art utility model, CN 116730757 A, discloses a microbial fertilizer fermentation device. The device includes a crushing assembly to crush raw materials, preventing them from clumping, and a stirring shaft to agitate the raw materials. However, while this prior art solves the problem of raw material agglomeration before entering the fermenter, once the raw materials accumulate inside the fermenter, they are stirred solely by a single stirring shaft, failing to fully mix the raw materials with the fermentation liquid, which can easily lead to incomplete fermentation. Therefore, we propose a microbial fertilizer circulation fermentation device. Utility Model Content

[0004] The utility model provides a microbial fertilizer circulating fermentation device, which solves the problem in the prior art that raw materials and fermentation liquid cannot be fully mixed, resulting in insufficient fermentation of the raw materials.

[0022] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 5 The present invention provides a technical solution: a microbial fertilizer circulation fermentation device, comprising a fermentation tank 16 mounted on a base 18, the top of the fermentation tank 16 is sealed by a sealing top cover 5, and a connecting shaft 23 extending into the fermentation tank 16 is rotatably connected to the sealing top cover 5. Figure 1 、 5 As shown, a pressure relief valve 20 and a pressure sensor 22 are connected to the bottom of the sealing top cover 5. The pressure sensor 22 can monitor the pressure in the fermentation tank 16 in real time. When the pressure is too high, the pressure can be relieved through the pressure relief valve 20 to avoid danger caused by excessive pressure.

[0024] like Figure 3 、 4 As shown, the upper end of the connecting shaft 23 passes through the top of the sealing top cover 5 and is fastened to the driving motor 21, and the driving motor 21 is connected to the sealing top cover 5, and a plurality of groups of stirring blades 2 are fastened on the outer wall of the connecting shaft 23 extending into the fermentation tank 16. The plurality of groups of stirring blades 2 are distributed from top to bottom on the connecting shaft 23, and each group of stirring blades 2 includes a mounting seat 3 fastened to the connecting shaft 23. The stirring blades 2 are circumferentially connected to the outer wall of the mounting seat 3, and a cleaning plate 12 is fastened to the bottom of the connecting shaft 23. A gap is set between the cleaning plate 12 and the inner bottom surface of the fermentation tank 16. The driving motor 21 drives the connecting shaft 23 to rotate. The stirring blades 2 connected to the connecting shaft 23 can stir the raw materials located in the middle of the fermentation tank 16, and the raw materials located at the bottom of the fermentation tank 16 are stirred and scraped away by the cleaning plate 12 to avoid the raw materials from accumulating at the bottom of the fermentation tank 16, thereby achieving sufficient stirring and mixing of the raw materials.

[0025] like Figure 1 、 2 As shown, a support frame 1 is symmetrically connected along the fermentation tank 16 on the base 18, and a mounting side plate 6 is symmetrically connected to the sealing top cover 5. The mounting side plate 6 is located above the support frame 1 and is connected to a first electric telescopic rod 7, and the bottom of the sealing top cover 5 and the top of the fermentation tank 16 are connected to a ring-shaped gasket 4 for sealing. A fixing seat 9 is symmetrically connected to the outer wall of the fermentation tank 16, and a second electric telescopic rod 8 is connected between the fixing seat 9 and the support frame 1. The second electric telescopic rod 8 and the first electric telescopic rod 7 are on the same straight line. The first electric telescopic rod 7 and the second electric telescopic rod 8 can respectively drive the sealing top cover 5 and the fermentation tank 16 to be raised and lowered. When the fermentation tank 16 and the sealing top cover 5 are separated, raw materials can be added. When the fermentation tank 16 and the sealing top cover 5 rise at the same time, the unloading operation of the raw materials after fermentation in the fermentation tank 16 is also facilitated, which brings great convenience to the operation.

[0026] In order to improve the stability of the fermentation tank 16 and the sealing top cover 5 when lifting and lowering, a guide rod 10 parallel to the second electric telescopic rod 8 is connected between the support frame 1 and the base 18. The guide rod 10 passes through the fixed seat 9. A connecting seat 11 is fastened to the adjacent side of the support frame 1. The end of the connecting seat 11 is connected to a support bracket 13 for supporting the bottom of the fermentation tank 16. When the fermentation tank 16 is fermenting, it can be lowered and located on the top of the support bracket 13. At this time, the support bracket 13 can provide stable support for the fermentation tank 16, thereby improving the stability of the overall placement of the fermentation tank 16.

[0027] In summary, the microbial fertilizer circulating fermentation device also includes a control box 17, in which a controller is arranged. When in use, the outer wall and the bottom of the fermentation tank 16 are respectively connected to the liquid inlet pipe 19 and the discharge pipe 14. The liquid inlet pipe 19 and the discharge pipe 14 are both connected to the solenoid valve 15. The liquid inlet pipe 19 is used to transport the fermentation liquid. After the fermentation liquid is transported to the fermentation tank 16, the fermentation liquid and the raw material can be fully mixed under the action of the stirring blade 2, and the first electric telescopic rod 7, the second electric telescopic rod 8, the drive motor 21, the pressure relief valve 20, the pressure sensor 22, and the solenoid valve 15 are all connected to the controller.

[0028] The raw materials to be fermented are placed in the fermentation tank 16, and the sealing top cover 5 is controlled to seal the top of the fermentation tank 16. At the same time, the liquid inlet pipe 19 transports the fermentation liquid into the fermentation tank 16. The stirring blades 2 and the cleaning plate 12 rotate at the same time, so that the raw materials and the fermentation liquid can be fully mixed, thereby ensuring that the raw materials are fully fermented. After the fermentation is completed, the first electric telescopic rod 7 and the second electric telescopic rod 8 drive the sealing top cover 5 and the fermentation tank 16 to move upward, thereby increasing the distance between the discharge pipe 14 and the base 18, making it easier to place the discharge device on the base 18, which brings great convenience to the staff. The fermentation tank 16 moves downward and sits on the support bracket 13, which can also improve the overall stability of the device. At the same time, the sealing top cover 5 and the fermentation tank 16 can slide toward each other, which also facilitates feeding.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
