Description
Technical Field
The invention belongs to the technical field of biology and new medicines, relates to the technical field of agricultural biology, particularly relates to the technical field of modern agricultural equipment and informatization, and particularly relates to a microbial pesticide spraying mechanism for a plant protection unmanned aerial vehicle.
Background
Microbial pesticide (microbial pesticide) is biological pesticide which takes bacteria, fungi, viruses and protozoa or genetically modified microorganism living bodies as active ingredients and prevents and treats pests such as diseases, insects, grasses, mice and the like; it comprises controlling insects with bacteria, controlling bacteria with bacteria, weeding with bacteria, etc.; the pesticide has the characteristics of strong selectivity, safety to people, livestock, crops and natural environment, no harm to natural enemies, difficult generation of resistance and the like; these microbial pesticides include bacteria, fungi, viruses, and the like, such as bacillus thuringiensis, beauveria bassiana, nucleopolyhedrovirus, clostridium botulinum exotoxin type C, and the like. The microbial pesticide can overcome the pollution of chemical pesticide to ecological environment, reduce the pesticide residue in agricultural and sideline products, improve the quality of the agricultural and sideline products, and favorably promote the economic growth of rural areas and the income increase of farmers.
Along with the rapid development of science and technology, the unmanned aerial vehicle is more and more widely used, the infrastructure related to agriculture is continuously improved, the demand of agricultural production on labor force can be greatly reduced by spraying microbial pesticide by using the plant protection unmanned aerial vehicle, and the plant protection unmanned aerial vehicle has the advantages of low operation height, less drift, hovering in the air, no need of a special take-off and landing airport, capability of increasing the penetrability of fog flow to crops due to downward airflow generated by a rotor wing, high prevention and control effect and the like; the existing plant protection unmanned aerial vehicle sprays microbial pesticide, generally, the microbial pesticide prepared in advance is loaded into a pesticide box of the plant protection unmanned aerial vehicle, then the plant protection unmanned aerial vehicle is controlled to take off for spraying, but the microbial pesticide prepared in advance is easy to precipitate, so that a large amount of microbial pesticide is deposited at the bottom of the pesticide box, the concentration of the pesticide in the early stage of spraying is easily too high, and the concentration of the pesticide in the later stage of spraying is too low, so that the spraying effect of the microbial pesticide is seriously influenced; because plant protection unmanned aerial vehicle is in crops upper portion when spraying microbial pesticide, make current plant protection unmanned aerial vehicle's sprinkling mechanism when spraying microbial pesticide, microbial pesticide very easily covers the plant top, but be difficult to cover the plant side completely, make microbial pesticide can not carry out whole spraying to the plant, and in order to guarantee the effect that microbial pesticide sprays, need once spray more between plant and guarantee microbial pesticide and spray the effect, adopt this kind of mode not only to consume more microbial pesticide easily, and can greatly increased use plant protection unmanned aerial vehicle spraying microbial pesticide's time, seriously influence spraying efficiency.
In order to facilitate use of the existing plant protection unmanned aerial vehicle, the pesticide box is directly arranged inside the plant protection unmanned aerial vehicle, but when the plant protection unmanned aerial vehicle sprays pesticides, the pesticide liquid in the pesticide box can shake, the flight stability of the plant protection unmanned aerial vehicle is seriously influenced, and the continuously-shaken pesticide liquid can corrode and damage the internal structure of the unmanned aerial vehicle to a certain extent, so that the service life of the unmanned aerial vehicle is greatly shortened; and inside the back with the plant protection unmanned aerial vehicle of medical kit setting, when needs carry out the microbial pesticide spraying, need add microbial pesticide and water in advance, after microbial pesticide and the water consumption that adds finishes, need add once more, seriously reduced plant protection unmanned aerial vehicle spray microbial pesticide's efficiency, increased the spraying cost.
