Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0039] Embodiment 1

[0040] The present invention is a production process of a biological organic fertilizer, comprising the following steps:

[0041] Step 1: Prepare organic fertilizer raw materials; select organic fertilizer ingredients, and stir and mix them to obtain organic fertilizer raw materials. The organic fertilizer ingredients include animal manure, and one or more of straw, wood ash or kaolin. If animal manure is used, straw, wood ash and kaolin are mixed in a certain proportion and stirred thoroughly.

[0042] Step 2: Pretreatment of organic fertilizer raw materials: Pretreatment of the organic fertilizer raw materials prepared in step 1 is performed by a pretreatment device. The pretreatment process is to add a culture solution into the organic fertilizer raw materials. The specific culture solution includes Bacillus subtilis and photosynthetic probiotic bacteria, lactic acid bacteria, yeast, actinomycetes or filamentous bacteria. For example, Bacillus subtilis and yeast are used and added to the organic fertilizer raw materials respectively.

[0043] Step 3: ferment the pretreated organic fertilizer raw materials to obtain fermented and decomposed materials, and then stir, dry and granulate them to obtain biological organic fertilizer. During the fermentation process, the temperature is controlled at 20-40°C, the relative humidity in the air is 60-80%, and the compost needs to be turned during the fermentation process.

[0044] like Figures 1 to 4 As shown, the pretreatment device in step 2 comprises a box body 1, the bottom of which is divided into two liquid-containing chambers 101 by a partition. The two liquid-containing chambers 101 contain a Bacillus subtilis solution and a yeast colony solution respectively.

[0045] The inner wall of the box body 1 is fixedly connected with a spray pipe 2 corresponding to the liquid chamber 101, and is rotatably connected with a driving wheel 301 corresponding to the liquid chamber 101. The spray pipe 2 is located above the liquid chamber 101. The spray pipe 2 is connected to a water pump through a pipeline, and the water pump is located in the liquid chamber 101. The two spray pipes 2 are respectively located on the side walls of the two liquid chambers 101 that are far away from each other.

[0046] Two driving wheels 301 are located on the same side wall of the box body 1, and the two driving wheels 301 are connected to the driving device 3. The driving device 3 is connected to the outer wall of the box body 1, and the two driving wheels 301 are connected to the side wall of the box body 1 through a rotating shaft, and the two rotating shafts are connected to a sprocket or a synchronous belt pulley, so that the two rotating shafts are connected to each other through a chain or a synchronous belt, and one of the rotating shafts is connected to the driving device 3, so that the two driving wheels 301 can be driven to rotate by one driving device 3, reducing the number of installed driving devices 3, which is conducive to reducing production costs.

[0047] like Figures 5 to 8 As shown, a feeding port 102 is provided on the side wall of the box body 1, and sliding seats 4 are slidably connected to the two inner side walls, and a rotating frame 5 is rotatably connected between the two sliding seats 4. A material holding frame 6 for holding organic fertilizer raw materials is installed in the rotating frame 5. One of the sliding seats 4 is provided with a through hole 401, which is used to take the material holding frame 6 out of and put it into the rotating frame 5 through the through hole 401, and take it out of and put it into the box body 1 through the feeding port 102.

[0048] The rotating frame 5 includes two rotating disks 503 , which are rotatably connected to the two sliding seats 4 , respectively. One of the rotating disks 503 is provided with a through slot 504 for the material holding frame 6 to pass through, and the through slot 504 corresponds to the through opening 401 .

[0049] Six or more fixing rods 505 are fixedly connected between the two turntables 503 . Six fixing rods are taken as an example in the figure. The six fixing rods 505 are distributed around the material holding frame 6 and fit with the outer wall of the material holding frame 6 , so that the position of the material holding frame 6 is limited by the fixing rods 505 .

[0050] like Figure 8 and 9 As shown, the material holding frame 6 includes a frame body 601 and a cover plate 602, and the side walls of the frame body 601 and the cover plate 602 are both perforated plate structures. The frame body 601 and the cover plate 602 enclose a rectangular box structure, and the frame body 601 and the cover plate 602 can be connected by screws or by buckles.

[0051] Two connecting ears 603 are welded to one end wall of the frame body 601, and the rotating frame 5 is provided with threaded holes 502 corresponding to the positions of the connecting ears 603 for fixing the relative positions of the material holding frame 6 and the rotating frame 5 by screws.

[0052] After the organic fertilizer raw materials are filled in the frame 601, the cover plate 602 is closed and pushed into the rotating frame 5 through the feed inlet 102, the through hole 401 and the through slot 504, and then screws are passed through the connecting ears 603 and connected and locked with the threaded holes 502, so as to fix the material containing frame 6 inside the rotating frame 5.

[0053] like Fig.10 As shown, the rotating disk 503 at one end of the rotating frame 5 is fixedly connected to the ring gear 501, and the box body 1 is equipped with a linear drive mechanism, such as a screw-nut mechanism, for driving the two sliding seats 4 to move. If the sliding seat 4 is driven to the right by the linear drive mechanism, the ring gear 501 is engaged with the driving wheel 301 and stops moving.

[0054] At this time, the driving device 3 is started, and the rotating frame 5 is driven to rotate through the driving wheel 301, and then the material holding frame 6 is driven to rotate through the rotating frame 5, and the culture solution is sprayed on the material holding frame 6 through the spray pipe 2, so that the culture solution can be fully integrated into the organic fertilizer raw materials in the material holding frame 6. In addition, the excess culture solution in the spraying process can be directly dripped into the liquid holding chamber 101 below, so as to achieve recycling.

[0055] Specifically, the spraying process includes:

[0056] a. The rotating frame 5 drives the material containing frame 6 to rotate counterclockwise at a speed n1 while spraying.

[0057] b. After spraying for a period of time, the rotating frame 5 drives the material holding frame 6 to rotate clockwise at a speed n1 while spraying. By rotating counterclockwise and clockwise during the spraying process, the organic fertilizer raw materials in the material holding frame 6 can be fully sprayed with the culture solution.

[0058] c. After spraying is completed, the rotating frame 5 drives the material containing frame 6 to rotate clockwise or counterclockwise at a rotation speed n2, and n2>n1, so that the rotating frame 5 rotates at a faster speed, so that the excess culture solution can be thrown out.

[0059] d. After spraying of one culture solution is completed, the sliding seat 4 is driven to the right by the linear drive mechanism, so that the rotating frame 5 drives the material holding frame 6 to move to the top of the liquid holding chamber 101 on the other side, so that the ring gear 501 is engaged with the driving wheel 301 at this position, and the above steps are repeated to spray another culture solution on the organic fertilizer raw material in the material holding frame 6.

[0060] e. After the spraying is completed, the rotating frame 5 drives the material holding frame 6 to move to the position of the material inlet 102, and the material holding frame 6 is taken out of the box body 1.

[0061] The use of the spraying method not only allows the culture solution to be more evenly integrated into the organic fertilizer raw materials, but also reduces the drainage process. When the rotating frame 5 drives the material holding frame 6 to rotate quickly, the excess culture solution can be fully thrown out to ensure that there is no excess culture solution, thereby effectively shortening the pretreatment time and effectively improving the pretreatment efficiency of the organic fertilizer raw materials.

In addition, an observation window 104 is provided on the side wall of the box body 1 for observing the spraying state of the organic fertilizer raw material during pretreatment, thereby greatly improving the overall convenience and practicality of use.
