Description

technical field [0001] The invention belongs to the technical field of biology and new medicine, relates to the field of agricultural biotechnology, in particular to the field of modern agricultural equipment and information technology, and specifically relates to a microbial pesticide spraying mechanism for a plant protection drone. Background technique [0002] Microbial pesticides refer to biological source pesticides that use bacteria, fungi, viruses, protozoa or genetically modified living microorganisms as active ingredients to prevent and control diseases, insects, grasses, rats and other harmful organisms; it includes bacteria to control insects, Use bacteria to control bacteria, use bacteria to kill weeds, etc.; this type of pesticide has strong selectivity, is safe for humans, livestock, crops and the natural environment, does not harm natural enemies, and is not easy to develop resistance; these microbial pesticides include bacteria, fungi, viruses, etc. , such as...

Problems solved by technology

[0003] With the rapid development of science and technology, the use of drones has become more and more extensive, and agricultural-related infrastructure has also been continuously improved. The use of plant protection drones for microbial pesticide spraying can greatly reduce the demand for labor in agricultural production. Plant protection UAVs have many advantages such as low operating height, less drift, hovering in the air, no need for special take-off and landing airports, and the downward airflow generated by the rotor helps to increase the penetration of fog to crops and high control effect; the existing plant protection UAVs spray microbial pesticides. Generally, pre-configured microbial pesticides are put into the medicine box of the plant protection drone, and then the plant protection drone is controlled to take off for spraying. However, the pre-configured microbial pesticides are prone to precipitation, which makes the microorganisms A large number of pesticides are deposited at the bottom of the medicine box, which may easily cause the concentration of the chemical solution in the early stage of spraying to be too high, while the concentration of the chemical solution in the later stage of spraying is too low, which seriously affects the spraying effect of microbial pesticides; The upper part of the crops makes the spraying mechanism of the existing plant protection drone spray microbial pesticides. The microbial pesticides can easily cover the top of the plants, but it is difficult to completely cover the sides of the plants, so that the microbial pesticides cannot be sprayed on the plants as a whole. For the effect of spraying, it is necessary to spray one more time between plants to ensure the spraying effect of microbial pesticides. This method not only consumes more microbial pesticides, but also greatly increases the time for using plant protection drones to spray microbial pesticides. Seriously affect the spraying efficiency

[0004] For the convenience of use, the existing plant protection drones directly set the medicine box inside the plant protection drone, but when the plant protection drone sprays pesticides, the liquid medicine in the medicine box will shake, which seriously affects the plant protection drone. flight stability, and the continuous shaking of the liquid medicine will also cause a certain degree of corrosion and damage to the internal structure of the drone, which greatly reduces the life of the drone; and after the medicine box is set inside the plant protection drone, when When it is necessary to spray microbial pesticides, it is necessary to add microbial pesticides and water in advance. When the added microbial pesticides and water are consumed, they need to be added again, which seriously reduces the efficiency of spraying microbial pesticides by plant protection drones and increases the cost of spraying
