Description

Technical Field

[0002] Bio-fertilizers can improve soil structure, enhance soil fertility, and reduce the pollution of the ecological environment caused by chemical fertilizers. The core process is composting and fermentation, which transforms organic matter in agricultural waste and industrial organic waste into fertilizer products rich in microorganisms.

[0003] Early bio-fertilizer production relied on open-air composting, requiring no specialized equipment and relying solely on manual turning of the compost. With the development of large-scale agriculture, fermentation began to be carried out by stirring in cylindrical or square containers. However, during this process, the organic matter inside some lumpy materials is difficult for microorganisms to come into contact with, and only the surface is decomposed. Waiting for complete decomposition requires a significant amount of time; if it is not fully decomposed, lumpy materials will mix into the fertilizer, thus reducing the quality of the bio-fertilizer in improving soil structure. Therefore, a bio-fertilizer composting fermentation device is proposed to solve these problems. Utility Model Content

The rotating rod 24 is fixedly connected to the output end of the motor 17. Multiple stirring rods 28 are fixedly connected to the middle of the rotating rod 24. The stirring rods 28 rotate with the rotating rod, stirring the materials inside the fermentation tank 1 and promoting the fermentation reaction. A fixing rod 27 is fixedly connected to the bottom of the rotating rod 24, and the fixing rod 27 transmits the rotational power of the rotating rod 24. The rotating force; scrapers 26 are fixedly connected to both sides of the fixed rod 27. The scrapers 26 rotate with the rotating rod 24 and slide on the inner wall of the fermentation funnel 7, which can scrape the material on the wall of the fermentation funnel 7 to prevent the material from sticking to the wall and affecting the fermentation effect. It can also help the material to be discharged from the discharge pipe 5. The bottom of the fermentation tank 1 is fixedly connected to the fermentation funnel 7. Its funnel-shaped structure allows the material to naturally converge under the action of gravity. With the help of the scrapers 26, the fermentation products can be discharged from the bottom more thoroughly. The scrapers 26 are slidably connected to the inside of the fermentation funnel 7. The inside of the fermentation tank 1 is filled with heat insulation cotton 25, which plays a role in keeping the fermentation product clean and dry. The fermentation funnel 7 is equipped with a heating element to maintain a stable temperature inside the fermentation tank 1. A discharge pipe 5 is fixedly connected to the bottom of the fermentation funnel 7, used to discharge the material after fermentation. A valve 4 is installed in the middle of the discharge pipe 5, which controls the discharge of fermentation products from the discharge pipe 5. A discharge cover 15 is installed on the top of the crushing box 16, ensuring a relatively closed environment inside the crushing box 16 during the crushing process, preventing material splashing and the entry of external impurities.

The support legs 3 serve to support the entire device. The fixing ring 29 is fixedly connected to one side of the support frame 6.

[0012] Working principle: When motor 12 is turned on, its output drives a rotating shaft 22 to rotate. Because the two rotating shafts 22 are linked by meshing gears 23, they rotate synchronously, and the spiral crushing rollers 21 on the outer side of the two rotating shafts 22 rotate accordingly. Lumpy materials are fed into the crushing box 16 through the discharge cover 15. The spiral crushing rollers 21 crush the large pieces of material through their spiral structure meshing and squeezing. The crushed material falls into the square funnel 11 and enters the transport pipe 9 through the conveying pipe 18. The rolling shaft 19 inside the transport pipe 9 rotates due to the rotational force of motor 20, thereby driving the spiral blades 20 to rotate. The spiral blades 20, with the help of spiral thrust, transport the material towards the fermentation tank 1. At the same time, the leachate from the material passes through the filter screen 30 and is discharged from the outlet pipe 8 at the bottom of the transport pipe 9. After the material enters the fermentation tank 1, motor 317 is started, driving the rotating rod 24 to rotate. The stirring rod 28, the fixing rod 27, and the scraper 26 on the rotating rod 24 operate synchronously. The stirring rod 28 agitates the material, promoting contact between microorganisms and organic matter; the scraper 26 slides along the inner wall of the fermentation funnel 7 to prevent the material from sticking to the wall; the insulation cotton 25 maintains a suitable temperature inside the tank, ensuring the activity of aerobic microorganisms and achieving the decomposition and maturation of organic matter. After fermentation is complete, the valve 4 is opened, and the fermented material is discharged from the discharge pipe 5 under the pushing of the stirring rod and its own gravity, completing the composting process.
