A device and method for killing agricultural pests by using drones to spray low-temperature airflow

Abstract

The invention discloses a device and method for killing agricultural pests by spraying a low-temperature airflow using a drone, comprising a main body, an incubator installed under the main body, a control device installed inside the main body, and a control device installed at the bottom of the main body The power supply; the incubator includes a box body, a partition, a wind source device and an air duct; a plurality of partitions are arranged in the box body, the box body is divided into several small chambers, and an air flow passage is formed between several small chambers; The wind source device is arranged in a small room at the inlet of the airflow channel; the air guide pipe is arranged in a small room at the outlet of the airflow channel; the control device includes a receiver, a governor and a controller; the receiver, the governor It is electrically connected with the controller; the governor is electrically connected with the wind source device; and the power supply is electrically connected with the wind source device and the control device respectively. The invention can achieve the effect of killing insects without using pesticides, and has no pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a device and method for killing agricultural pests by using drones to spray low-temperature airflow. Background technique [0002] Crop pests are a major difficulty in agricultural production. The current control measures mainly use pesticides to kill pests manually. Although good results can be achieved, the use of pesticides has a relatively large adverse effect on the farmland environment and surrounding organisms. [0003] The use of aircraft to spray pesticides can overcome the problems of low labor efficiency and small scope, but the cost cannot be well controlled, and it is also relatively dangerous. With the continuous improvement and application of multi-axis and multi-rotor aircraft structures and control methods in various fields at home and abroad in recent years, multi-rotor aircraft has entered various fields for operations by virtue of its own characteristics.

Problems solved by technology

[0004] The use of low temperature in the natural environment, such as seasonal changes, can effectively inhibit the occurrence and spread of pests, but it is not controlled and cannot be used as an artificial means

If the traditional compressor method is used to produce low-temperature airflow, although it can meet the requirements of flexibility and controllability, the equipment is heavy and consumes a lot of power, so it is not suitable for use by aviation spraying
