However, the existing unmanned aerial vehicle-mounted microbial agent spraying and curing device and technology still have key technical defects in practical application, and particularly the design in the raw material supplying and mixing links is unreasonable, so that the stability and reliability of the slope curing effect are seriously affected. At present, a conventional unmanned aerial vehicle-mounted spraying device generally adopts a disposable feeding mode, namely microbial agents and required supplementary raw materials are all fed into a mixing tank at one time before operation, and then are mixed by a stirring mechanism and sprayed, but excessive raw materials are fed once to easily cause material accumulation in the mixing tank, even if the stirring mechanism is arranged, the raw materials with high concentration and large accumulation are fully and uniformly mixed with the microbial agents in a short time, and the problems of overhigh local raw material concentration and unbalanced mixing system proportion are extremely easy to occur. After the unevenly mixed materials are sprayed on the surface layer of the side slope, the reaction degree of the microbial inoculum, soil particles and water is inconsistent, so that the strength of a cementing layer formed on the surface layer of the side slope is uneven, the curing effect of a partial area is insufficient, the slippage and the soil erosion cannot be effectively resisted, and the overall quality and the long-term stability of the curing of the side slope are seriously affected.
