[0031] See also Fig. 9In this embodiment, specifically, one set of driving shafts 14 is fixedly connected to the output shaft of the driving motor 19, and another set of driving shafts 14 and the stirring shaft 5 are respectively fixedly provided with a set of synchronous pulleys, and the two sets of synchronous pulleys are sleeved with synchronous belts 22. Under the action of the synchronous belts 22, the stirring shaft 5 drives the other set of driving shafts 14 to rotate synchronously with it, and a lifting shaft 23 is rotatably provided between the opposite side walls of the driving box 16, and an active conical wheel 24 is fixedly provided on the transmission shaft 13, and a There is a driven conical wheel 25, and the driving conical wheel 24 is meshed with the driven conical wheel 25.

[0034] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 The side wall cleaning scraper 33 is connected to the side wall of the fermenter 1 by the gap adjustment component.

[0035] As a further improvement of this embodiment, the cross section of the side wall cleaning scraper 33 is an arc-shaped structure adapted to the inner wall of the fermentation tank 1 , thereby ensuring that the side wall cleaning scraper 33 fits the side wall of the fermentation tank 1 .

[0036] See also Figure 3 and Figure 4 In this embodiment, specifically, the gap adjustment assembly includes a slide 34, an electromagnet 35, a magnet 36 and a slide post 37.

When the side of the electromagnet 35 facing the magnet 36 has an opposite polarity to the magnet 36, an attractive force is generated on the magnet 36, and the side wall cleaning scraper 33 is driven away from the fermentation tank 1 under the cooperation of the magnet 36 and the slide column 37, so that the stirring mechanism 2 and the side wall cleaning scraper 33 can rotate smoothly in the fermentation tank 1 to perform the stirring action.

[0039] In specific use, when the lifting rod 7 is raised or lowered, the fertilizer adhered to the surface of the lifting rod 7 can be scraped and removed by the arrangement of the cleaning member 39 .

[0040] See also Figure 2 , Figure 3 and Figure 5In this embodiment, specifically, the bottom wall of the fermentation tank 1 is a funnel-shaped structure, and a bottom wall cleaning scraper 40 is provided on the bottom wall of the connecting plate 31. The bottom wall cleaning scraper 40 is used to scrape and clean the bottom wall of the fermentation tank 1.

The air inlet pipe 43 can be used to add oxygen required for fermentation into the fermentation tank 1, and the exhaust pipe 44 can be used to discharge the reaction waste gas in the fermentation roller.

[0042] It is worth noting that there are at least two groups of feeding ports 41 on the top wall of the fermentation tank 1, one group for adding solid raw materials and the other group for adding liquid raw materials. In actual production, in order to ensure the fermentation production efficiency, a sealing valve is provided on the feeding port 41. Since the structure of providing a sealing valve on the feeding port 41 is a prior art, it will not be described in detail in this solution.

[0043] The present embodiment provides a reaction and fermentation device for fertilizer production, and the specific working principle is as follows: (1) Fertilizer raw materials are added into the fermentation tank 1 through the feeding port 41, and the driving motor 19 is started. The driving motor 19 drives the driving gear 20 to rotate, and the meshing of the driving gear 20 and the driven gear 21 drives the stirring shaft 5 to rotate. The stirring shaft 5 drives the main stirring plate 6 to rotate through the engagement of the locking protrusion 11 and the locking groove 12. When the main stirring plate 6 rotates, the fertilizer raw materials in the fermentation tank 1 are stirred; At the same time, the driving motor 19 drives one set of driving shafts 14 to rotate, and the stirring shaft 5 drives another set of driving shafts 14 to rotate under the action of the synchronous belt 22. The two sets of driving shafts 14 respectively drive the fan gears 18 fixed thereon to rotate, and the two sets of fan gears 18 intermittently mesh with the transmission gear 17. Since the rotation directions of the two sets of fan gears 18 are opposite, the transmission shaft 13 can be driven to rotate forward and reverse intermittently; the transmission shaft 13 drives the active conical wheel 24 to rotate, and the active conical wheel 24 meshes with the driven conical wheel 25 to drive the lifting shaft 23 to rotate, and the lifting shaft 23 retracts and releases the lifting rope 27 through intermittent forward and reverse rotation; When the lifting shaft 23 reels the lifting rope 27, the lifting rod 7 is driven to rise in the fermentation tank 1 through the lifting rope 27. When the lifting shaft 23 unwinds the lifting rope 27, the lifting rod 7 is driven to descend in the fermentation tank 1 through the lifting rope 27. When the lifting rod 7 rises, the cleaning member 39 cleans the portion of the lifting rod 7 passing through the cleaning member 39. When the lifting rod 7 rises, the lower push plate 10 applies an upward thrust to the main turning and mixing plate 6, thereby driving the rotating main turning and mixing plate 6 to rise; when the lifting rod 7 descends, the upper push plate 9 applies a downward thrust to the main turning and mixing plate 6, thereby driving the rotating main turning and mixing plate 6 to descend; the main turning and mixing plate 6 is lifted and lowered while rotating, thereby increasing the turning and mixing coverage of the main turning and mixing plate 6; (2) During the rotation of the mixing shaft 5, the connecting plate 31 drives the mounting vertical plate 32 to rotate synchronously, and the mounting vertical plate 32 drives the auxiliary mixing rod 38 to rotate synchronously, thereby cooperating with the main mixing plate 6 to improve the mixing efficiency; (3) In the initial state, the magnetic poles of the electromagnet 35 and the magnet 36 are opposite to each other. Under the action of the electromagnet 35, the magnet 36 is attracted, so that the side wall cleaning scraper 33 is away from the inner wall of the fermenter 1. When the side wall of the fermenter 1 needs to be cleaned, the magnetic pole direction of the electromagnet 35 is changed. The magnetic poles of the electromagnet 35 and the magnet 36 are the same on the opposite side. Under the action of the electromagnet 35, the magnet 36 is repelled, so that the side wall cleaning scraper 33 is in contact with the inner wall of the fermenter 1. As the stirring shaft 5 rotates, the side wall cleaning scraper 33 is driven to clean the inner wall of the fermenter 1.
