[0017] Compared with the prior art, the present application has the following advantages:

[0018] , the straw provides a carbon source, the fecal pollution supplements a nitrogen source, the diatom earth is rich in silicon elements to enhance the lodging resistance of seedlings, the biochar adsorbs heavy metals and fixes carbon, realizes nutrient complementation and improves the synergy of multi-source solid waste, and improves the fertility; by integrating agricultural, garden, food processing and other multi-field waste, the pressure of incineration and landfill is reduced;

[0021] , the material conveying belt body drives a plurality of material conveying buckets to move in an intermittent closed loop, the opening of the material conveying bucket faces upward for containing the medium-temperature anaerobic fermentation material, at this time, the electric telescopic rod one is shortened to stack the upper pushing shell on the supporting base; after subsequent proportioning and mixing with the high-temperature aerobic fermentation material, when the material conveying bucket moves to the opening facing downward, the electric telescopic rod one is started to lengthen, the upper pushing shell pushes out the mixed material of the high-temperature aerobic fermentation material and the medium-temperature anaerobic fermentation material outside along the material conveying bucket; the mixed material with high viscosity of the medium-temperature anaerobic fermentation material is accurately and completely pushed out; meanwhile, a plurality of penetrating columns are correspondingly controlled by a plurality of electric telescopic rods four to penetrate into the medium-temperature anaerobic fermentation material, and then are withdrawn, a plurality of proportioning holes are formed on the medium-temperature anaerobic fermentation material, the high-temperature aerobic fermentation material is quickly mixed into the medium-temperature anaerobic fermentation material, pre-proportioning is realized, and the subsequent mixed pulp preparation is facilitated;

Multiple proportioning holes are formed in the flat mesophilic anaerobic fermentation material zone along with multiple intersecting columns, creating a pre-mixed state of the mesophilic anaerobic fermentation material. High-temperature aerobic fermentation material enters the material chamber through the feed hood and feed pipe. Multiple aeration holes on the aeration plate blow high-speed air from inside the air chamber onto the high-temperature aerobic fermentation material, spraying and spreading it flat on the mesophilic anaerobic fermentation material zone, thus forming a high-temperature aerobic fermentation material zone. This allows the high-temperature aerobic fermentation material and the mesophilic anaerobic fermentation material to be pre-mixed in a proportional manner, forming a stable, unitized pre-mixed state, which is beneficial for subsequent efficient and rapid pulping. This overcomes the significant difference in physical properties between the dried fibers of the high-temperature aerobic fermentation material and the viscous fecal matter of the mesophilic anaerobic fermentation material, which can easily lead to localized clumping.

[0023] After spreading the mesophilic anaerobic fermentation material inside the material conveying hopper, a sealed conveyor belt can be used to ensure that the mesophilic anaerobic fermentation material is in an anaerobic environment as much as possible, so as to maintain the anaerobic environment and protect the activity of lactic acid bacteria.
