It can be understood that, the chicken manure, the egg shells and the mushroom residues are added into the fermentation tank, and then the microbial additive is added into the chicken manure, the egg shells and the mushroom residues to perform a primary fermentation operation, so that more acidic substances are generated in the fermentation process of the chicken manure, the egg shells and the mushroom residues, and the microbial additive is suitable for survival under neutral and weakly alkaline conditions, and the activity of the microbial additive is reduced or even the microbial additive is inactivated under the acidic conditions.

S200, adding the chicken manure, the egg shells and the mushroom residues into the primary fermentation product, and performing secondary fermentation treatment on the primary fermentation product at a three-stage fermentation temperature. It can be understood that the chicken manure, the egg shells and the mushroom residues which are not subjected to fermentation treatment are added in the secondary fermentation treatment process, because the macromolecular organic matter content of the unfermented chicken manure, the egg shells and the mushroom residues is more, the filamentous fungi, the saccharomycetes and the lactobacillus play a leading role, and for the primary fermentation product which is subjected to primary fermentation, the saccharomycetes, the photosynthetic bacteria, the bacillus subtilis and the actinomycetes play a leading role, and the microbial additives play a common role, so that in the initial period of the secondary fermentation treatment process, the temperature of the primary fermentation product is rapidly increased, the problem that the temperature of the primary fermentation product after primary fermentation operation is lower, the temperature of the primary fermentation product is increased by increasing external energy consumption, and the energy consumption is increased is solved. In the process of secondary fermentation treatment, along with the continuous rise of the temperature of the primary fermentation product after the initial period, the content of small molecular substances in the primary fermentation product is increased, photosynthetic bacteria, actinomycetes and filamentous fungi play a leading role, and the photosynthetic bacteria, the actinomycetes and the filamentous fungi reproduce a large amount of propagules in each step in the early stage, so that in the process of secondary fermentation treatment, the temperature of the primary fermentation product is greatly increased in a short time, organic matters in the primary fermentation product are further decomposed in the process of temperature rise, and a large amount of pathogens, worm eggs and miscellaneous vegetable seeds in the primary fermentation product are inactivated. At the end of the second fermentation treatment, due to the continuous rise of the temperature of the primary fermentation product, the activity of photosynthetic bacteria and bacillus subtilis is gradually reduced, the cellulose content is still higher and the content of small molecular organic matters is further increased, lactobacillus and filamentous bacteria play a leading role, the temperature of the primary fermentation product is slowly increased, in the process of slowly increasing the temperature, pathogens, eggs and miscellaneous vegetable seeds in the primary fermentation product are further inactivated, but degradable substances in the primary fermentation product are gradually reduced, and due to the influence of high temperature, the activity of each bacterium in the primary fermentation product is reduced, so that the heat production of the primary fermentation product is less than heat dissipation, the temperature of the primary fermentation product is gradually reduced, the fully fermented and rotten fermentation product is finally obtained, and the complete rotten chicken manure is ensured by adopting the three-stage fermentation temperature to carry out secondary fermentation treatment on the primary fermentation product, so that the quality of the fermentation product is high.

S300, performing aging operation on the primary fermented product after the secondary fermentation treatment to obtain a fermented product. It can be understood that the primary fermented product after the secondary fermentation treatment is aged, so that the particle consistency of the fermented product is effectively improved, the metastable state crystal form precipitate in the organic fertilizer forms a stable crystal form precipitate, and the incomplete crystal precipitate in the fermented product is changed into the complete crystal precipitate.

S400, crushing and mixing the fermented product to obtain mixed fermented powder. It can be understood that the organic fertilizer after fermentation and decomposition is blocky or granular substances with different sizes, that is, the fermented product is blocky or granular substances with different sizes, and the fermented product is crushed and mixed, so that the grain size of the fermented product is reduced and homogenized.

In one embodiment, the three-stage fermentation temperature comprises a first stage temperature, a second stage temperature and a third stage temperature, wherein the second stage temperature is greater than the first stage temperature and the third stage temperature. It can be understood that, in order to reduce the energy consumption of the secondary fermentation treatment, the temperatures of the respective stages of the secondary fermentation treatment are made to be adjusted based on the actual temperature of the primary fermented product during the secondary fermentation treatment, i.e., the secondary temperature is made to be greater than the primary temperature and the tertiary temperature.

wherein the second-stage temperature comprises a second temperature and a third temperature, and the primary fermentation product after the first fermentation treatment is subjected to second fermentation treatment under the second temperature condition; and performing third fermentation treatment on the primary fermentation product after the second fermentation treatment under a third temperature condition. It can be understood that the temperature of the primary fermentation product in the secondary fermentation treatment process changes along with the change of the fermentation time, so that in the process of adjusting the temperature of the secondary fermentation treatment, the temperature of each stage of the secondary fermentation treatment is adjusted based on the actual temperature of the primary fermentation product in the secondary fermentation treatment process, so that pathogens, ova and miscellaneous vegetable seeds in the primary fermentation product are fully inactivated, and the energy consumption of the secondary fermentation treatment is reduced.

In one embodiment, the first temperature is 25 ℃ to 45 ℃; the second temperature is 45-60 ℃; the third temperature is 60-70 ℃; the temperature of the third section is 35-55 ℃. It can be understood that, in the process of the secondary fermentation treatment, the temperature of the primary fermentation product can be gradually increased, and in order to reduce the energy consumption of the secondary fermentation treatment, the temperature of each stage of the secondary fermentation treatment is adjusted based on the actual temperature of the primary fermentation product in the process of the secondary fermentation treatment, so that pathogens, worm eggs and miscellaneous vegetable seeds in the primary fermentation product are fully inactivated, and the energy consumption of the secondary fermentation treatment is reduced. Specifically, the chicken manure, the eggshell and the mushroom residues which are not subjected to fermentation treatment are added in the secondary fermentation treatment process, because the macromolecular organic matter content of the unfermented chicken manure, the eggshell and the mushroom residues is high, the filamentous fungi, the yeasts and the lactobacillus play a leading role, and for the primary fermentation product which is subjected to primary fermentation, the yeasts, the photosynthetic bacteria, the bacillus subtilis and the actinomycetes play a leading role, and the microbial additives play a common role, so that the temperature of the primary fermentation product in the primary fermentation treatment process of the secondary fermentation treatment is rapidly increased, the problems that the temperature of the primary fermentation product is low, the external energy consumption needs to be increased to heat the primary fermentation product, and the energy consumption is increased are solved. In the process of carrying out the second fermentation treatment after the first fermentation treatment, the temperature of the primary fermentation product rises, the content of small molecular substances in the primary fermentation product at the moment is increased, the photosynthetic bacteria, the actinomycetes and the filamentous fungi play a leading role, and the photosynthetic bacteria, the actinomycetes and the filamentous fungi reproduce a large amount of propagules in each step in the early stage, so that in the process of the second fermentation treatment, the temperature greatly rises in a short time, organic matters in the primary fermentation product are further decomposed in the process of temperature rise, and a large amount of pathogens, worm eggs and miscellaneous vegetable seeds in the primary fermentation product are inactivated. In the process of carrying out the third fermentation treatment after the second fermentation treatment, due to the rising of the temperature, the activities of the photosynthetic bacteria and the bacillus subtilis are gradually reduced, the cellulose content is still higher at the moment, the content of the small molecular organic matters is further increased, the lactobacillus and the filamentous bacteria play a leading role, the temperature of the primary fermentation product is slowly increased, and in the process of slowly increasing the temperature, pathogens, worm eggs and miscellaneous vegetable seeds in the primary fermentation product are further inactivated. In the process of carrying out the fourth fermentation treatment after the third fermentation treatment, the degradable substances in the primary fermentation product are gradually reduced, and due to the influence of high temperature, the activity of each bacterium in the primary fermentation product is reduced, so that the temperature of the primary fermentation product is gradually reduced, and finally, the fully fermented and decomposed fermentation product is obtained.

In one embodiment, the primary fermentation product is subjected to a secondary fermentation process by intermittent oxygen supply. It can be understood that in the secondary fermentation treatment process, the bacteria playing the leading role are different, in order to better play the role of the leading bacteria, the primary fermentation product is subjected to secondary fermentation treatment by adopting an intermittent oxygen supply mode, and the fermentation and decomposition sufficiency of the chicken manure, the egg shells and the mushroom residues is better improved.

Referring to fig. 4 and 6, in one embodiment, the dung cleaner 10 further includes a heating element assembly 500, the heating element assembly 500 is disposed between the driving roller 220 and the first scraper 320, and the heating element assembly 500 is located on a side of the conveyor belt 240 close to the driving roller 220 and connected to the mounting base 100. It can be understood that if the amount of the chicken manure reaching the cleaning roller brush assembly 410 is large, i.e. the amount of the chicken manure with water content scraped by the first scraper 320 is small, the amount of the chicken manure to be dehydrated subsequently is increased, the time and labor for treating the chicken manure are increased, further, in the dung cleaner 10 of the present application, such that the heat-generating body assembly 500 is disposed between the drive roller shaft 220 and the first scraper 320, and the heat-generating body assembly 500 is positioned at a side of the transfer belt 240 close to the driving roller shaft 220 and connected with the mounting seat 100, that is, the heat generating body dries the chicken manure on the transfer belt 240 between the first scraper 320 and the drive roller shaft 220, thereby effectively reducing the water content of the chicken manure on the transfer belt 240 between the first scraper 320 and the drive roller shaft 220, so that the chicken manure on the conveyor belt 240 can be mostly scraped and collected by the first scraper 320, and the collecting and processing time of the chicken manure is effectively reduced.

in the preparation method of the powder organic fertilizer, the microbial additive and the pH regulator are added into the chicken manure, the egg shells and the mushroom residues to perform primary fermentation operation, so that the living environment of the microbial additive is neutral or slightly alkaline, the chicken manure, the egg shells and the mushroom residues are added into the primary fermented product, and the primary fermented product is subjected to secondary fermentation treatment at a three-stage fermentation temperature, so that pathogens, worm eggs and miscellaneous vegetable seeds in the primary fermented product are fully inactivated, the biological activity of the microbial additive in each time period is fully exerted, the complete decomposition of the chicken manure is further ensured, and the quality of the fermented fertilizer is higher.
