[0002] The forestry airborne target spraying device refers to a device used for spraying pesticides on targets in forestry operations. This device is usually installed on a drone or a helicopter to effectively spray insecticides, herbicides or other chemical agents in a large range of forests to control pests, diseases or weeds, protect the health of trees and the ecological balance of forests. The device usually has precise spraying function, which can adjust the dosage and range of spraying as needed to ensure the effective use of pesticides and accurate coverage of targets. The use of airborne target spraying device can improve the efficiency and coverage of spraying, reduce labor costs and operation time, and reduce the impact on the environment.

[0003] The forestry airborne target spraying device plays an important role in forest pest control and is one of the important tools in modern forestry management. There are many different types of airborne target spraying devices on the market, but the existing airborne target spraying devices usually have fixed structure design. However, in actual work process, the spraying range of the device is usually covered or single directional, the covered spraying device is more suitable for large area forest disease control, when the trees in the forest are planted at equal intervals, this large range covered spraying method will cause a lot of waste of pesticides, and cannot be better applied to target trees. Due to the large amount of pesticide consumption, the pesticide needs to be frequently replenished, thereby reducing the efficiency of spraying work; the directional spraying device is usually suitable for small forest farms or large planting interval forest farms, and due to its small spraying coverage, it also affects the spraying efficiency to some extent.

[0011] Further, the connecting mechanism comprises mounting racks fixed to the top of the two sides of the medicine storage box, and two mounting holes are formed in each of the two mounting racks.

[0014] Through the above technical solution, the air supply mechanism can provide high-speed airflow for the ring-shaped medicine spraying mechanism and the bottom medicine spraying mechanism when working, so that the direction and range of the medicine spraying can be interfered by the high-speed airflow, and the ring-shaped medicine spraying mechanism and the bottom medicine spraying mechanism can perform large-area covering spraying, small-range accurate directional spraying or two-side uniform spraying according to different situations. In actual work, after the air supply fan is powered on, the air supply fan will suck a large amount of air through the plurality of groups of air inlet holes, and then the airflow will enter the flow guide cover. Under the adjustment and control of the rotation adjustment mechanism, the high-speed airflow will flow out through a specific channel, so as to interfere with the sprayed medicine by wind power.

[0015] Further, the annular air guide mechanism comprises a bottom cover plate fixedly installed on the annular frame, a plurality of uniformly distributed fixed clamping seats are fixedly connected to the bottom periphery of the bottom cover plate, an inner spraying annular groove and an outer spraying annular groove are respectively formed in the top of the bottom cover plate, a plurality of uniformly distributed inner spraying through holes are formed in the bottom of the inner spraying annular groove, a plurality of uniformly distributed outer spraying through holes are formed in the bottom of the outer spraying annular groove, a plurality of inner spraying flow guide nozzles penetrating the inner spraying through holes are fixedly connected to the bottom periphery of the bottom cover plate, and a plurality of outer spraying flow guide nozzles penetrating the outer spraying through holes are also fixedly connected to the bottom periphery of the bottom cover plate.

[0016] Through the above technical scheme, the annular air guide mechanism is mainly used for controlling the direction control of the air flow blown by the air supply fan, and the direction, range and state of the pesticide spraying can be accurately controlled by cooperating with the rotary adjusting mechanism. The inner spraying through holes, the outer spraying through holes and the center through holes are respectively formed in the bottom cover plate, and the air flow can flow out through the corresponding through holes under the adjusting control of the rotary adjusting mechanism.

[0017] Further, the annular pesticide spraying mechanism comprises a pesticide pumping device installed on the air supply mechanism, the liquid inlet of the pesticide pumping device is connected with a first pesticide pumping pipe and a second pesticide pumping pipe, the other ends of the first pesticide pumping pipe and the second pesticide pumping pipe are communicated with a pesticide storage tank, the liquid outlet of the pesticide pumping device is connected with a pesticide supply pipe, the other end of the pesticide supply pipe is connected with a first annular flow guide pipe, the first annular flow guide pipe is clamped and fixed on the plurality of fixed clamping seats, a plurality of uniformly distributed atomizing nozzles are arranged on the first annular flow guide pipe, and an independent first electromagnetic valve is installed on each atomizing nozzle.

Since an independent first electromagnetic valve is installed on each atomizing nozzle, the spraying state of each atomizing nozzle can be independently controlled through the corresponding first electromagnetic valve, thereby realizing the adjustment of the pesticide spraying state. When large-area covering spraying is needed, a plurality of atomizing nozzles can be opened at the same time.
