Description

Technical Field

[0001] This utility model relates to the technical field of fermentation equipment, specifically to a fermentation equipment for the production of agricultural microbial fertilizers. Background Technology

[0002] Microbial fertilizers, also known as bio-fertilizers or microbial fertilizers, are environmentally friendly fertilizers that utilize the life activities of beneficial microorganisms to improve plant nutrition and promote growth. Their core functions include: converting atmospheric nitrogen into nitrogen that plants can absorb (nitrogen fixation), decomposing insoluble phosphorus and potassium elements in the soil (phosphorus and potassium solubilization), and secreting plant growth hormones to stimulate crop growth. Compared with traditional chemical fertilizers, microbial fertilizers have advantages such as low energy consumption, low pollution, and the ability to improve soil microecology.

[0003] In existing technologies, fermentation equipment is required for the fermentation of microbial fertilizers. However, existing fermentation equipment often only has a single stirring function. For example, utility model patent application number 202220853076.9 provides a fermentation device for agricultural microbial fertilizer production, including a box, a support plate, a fermentation chamber, and a high-efficiency stirring device. The support plate is located inside the box, the fermentation chamber is located on the bottom wall of the box, and the high-efficiency stirring device is located on the support plate. The high-efficiency stirring device includes a top chute, a top sliding block, a top sliding rod, an electric telescopic rod, a connecting block, a connecting column, a bottom chute, a stirring rod, a stirring shaft, a drive motor, an adjusting block, an adjusting rod, a connecting plate, and a bottom sliding rod. The top chute is located below the top wall of the box, and the bottom chute is located on the support plate. Improving the stirring effect accelerates the fermentation speed. However, fermentation requires not only stirring but also oxygen supply to promote microbial reproduction while dissipating heat and preventing localized anaerobic conditions that could produce odors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fermentation device for the production of agricultural microbial fertilizers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a fermentation device for the production of agricultural microbial fertilizer, comprising a fermentation tank and a stirring mechanism. The fermentation tank is equipped with a top cover, and the top cover is provided with an annular connecting chamber. The fermentation tank is provided with a replenisher that is rotatably connected to the top cover. The replenisher consists of an annular outer shell and an annular inner shell installed inside the annular outer shell. The bottom plate of the annular outer shell has multiple replenishment holes.

[0008] As a preferred technical solution of this utility model, the transmission assembly includes a drive gear and a transmission gear. The drive gear is sleeved and fixed outside the stirring rod. The transmission gear meshes with the drive gear and the transmission gear. A rotating rod is installed on the transmission gear, and one end of the rotating rod is rotatably connected to the top cover.

[0009] As a preferred embodiment of this utility model, an annular connection interface is formed between the annular outer shell and the annular inner shell, which communicates with the annular connecting chamber.

[0010] As a preferred embodiment of this utility model, the top of the annular connecting chamber is provided with at least two connecting pipes, and the inner and outer sides of the annular connecting chamber are provided with annular connecting protrusions.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model discloses a fermentation device for agricultural microbial fertilizer production, including a fermentation tank 1 and a stirring mechanism. The fermentation tank 1 is equipped with a top cover 3, and the top cover 3 is provided with an annular connecting chamber 33. The fermentation tank 1 is provided with a replenisher 5 rotatably connected to the top cover 3. The replenisher 5 is composed of an annular outer shell 51 and an annular inner shell 53 installed inside the annular outer shell 51. The bottom plate of the annular outer shell 51 is provided with a plurality of replenishment holes 55. The inner wall of the annular bottom plate of the annular outer shell 51 is provided with a set of transmission teeth 54 distributed in a ring. The inner side of the annular bottom plate is also provided with a transmission component.

[0025] The stirring mechanism includes a stirring motor 2 and a stirring rod 6. The stirring motor 2 is installed on the top of the top cover 3. The upper end of the stirring rod 6 passes through the top cover 3 and is connected to the output shaft of the stirring motor 2. The outer wall of the stirring rod 6 is provided with several stirring blades 7. The stirring motor 2 controls the stirring rod 6 to rotate, and the stirring rod 6 drives the stirring blades 7 to stir the fertilizer, thereby improving the fermentation efficiency.

[0026] The transmission assembly includes a drive gear 8 and a transmission gear 10. The drive gear 8 is sleeved and fixed outside the stirring rod 6. The transmission gear 10 meshes with the drive gear 8 and the transmission teeth 54. A rotating rod 9 is installed on the transmission gear 10. One end of the rotating rod 9 is rotatably connected to the top cover 3. The stirring rod 6 drives the drive gear 8 to rotate. The meshing of the drive gear 8 and the transmission gear 10 drives the transmission gear 10. The meshing of the transmission gear 10 and the transmission teeth 54 causes the supplementer 5 to rotate. With the help of the rotating supplementer 5, oxygen or water can be replenished more evenly.

[0027] Among them, an annular connecting interface 52 is formed between the annular outer shell 51 and the annular inner shell 53, which communicates with the annular connecting chamber 33. The annular connecting interface 52 can be rotatably connected to the annular connecting protrusion 32 through a bearing, so that the supplementer 5 is rotatably set at the bottom of the top cover 3.

[0028] The annular connecting chamber 33 has at least two connecting pipes 31 on its top. Both the inner and outer sides of the annular connecting chamber 33 have annular connecting protrusions 32, forming mounting grooves between the annular connecting protrusions 32 and the annular connecting chamber 33. These mounting grooves cooperate with the annular connecting interface 52 and can accommodate bearings. The corresponding connecting pipes 31 are connected to the oxygen supply system or water supply system via pipes. Since the connecting pipes 31 are located on the annular connecting chamber 33 and do not rotate with the replenisher 5, they can be easily connected to the oxygen supply system or water supply system, avoiding pipe entanglement. Furthermore, the connecting pipes 31 can also be used to install automatic air vents for automatic air venting.

[0029] The fermentation tank 1 has a discharge port at the bottom, and a discharge valve 4 is connected to the discharge port. The upper part of the fermentation tank 1 is connected to a feed hopper, and a cover plate is movably connected to the feed hopper. The cover plate can be connected to the feed hopper by a hinge. The specific installation structure of the cover plate is not limited here, so it is not marked in the attached figure. When the discharge valve 4 is opened, the fermented fertilizer can be discharged from the fermentation tank 1.

[0030] During operation, raw materials are fed into fermentation tank 1 through the feed hopper, and the cover is closed. The stirring rod 6 is rotated by the stirring motor 2, and the stirring blade 7 is used to stir the fertilizer. Oxygen or water enters the annular connecting chamber 33 through the corresponding connecting pipe 31, enters the replenisher 5 through the annular connecting interface 52, and is then sprayed out through the replenishment hole 55 to replenish oxygen or water. When the stirring rod 6 rotates, it also drives the drive gear 8 to rotate. The meshing of the drive gear 8 with the transmission gear 10 drives the transmission gear 10. The meshing of the transmission gear 10 with the transmission teeth 54 makes the replenisher 5 rotate. With the help of the rotating replenisher 5, oxygen or water can be replenished more evenly.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
