Pesticide spraying device of unmanned aerial vehicle

Abstract

The invention discloses a pesticide spraying device of an unmanned aerial vehicle. The pesticide spraying device comprises a machine body, a supporting frame fixed on the left side and the right side of the bottom of the machine body, and a rotor wing mechanism rotationally installed on the top of the machine body, wherein the machine body comprises an upper machine main body and a lower machine main body, a pesticide storage cavity is formed in the lower machine main body, a first cavity in the portion, above the pesticide storage cavity, of the lower machine main body, a second cavity is arranged in the portion, on the right side of the first cavity, in the lower machine main body, and a motor is fixedly arranged in the portion, between the second cavity and the first cavity, in the lower machine main body; a first bevel wheel extending into the first cavity is connected with the tail end of the left side of the motor in a matched mode, and a second bevel wheel is connected with the inside of the first cavity in the top of the left side of the first bevel wheel in a meshing mode; a rotating shaft which extends upwards is fixedly arranged on the end surface of the top of the second bevel wheel, and the extending tail end of the top of the rotating shaft is fixedly connected with the bottom of the rotor wing mechanism. The pesticide spraying device is simple in structure, can achieve automatic flying and pesticide stirring, can reduce the flying loss of the unmanned aerial vehicle, enlarges the spraying range, and improves the spraying efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural spraying, and relates to a pesticide spraying device for an unmanned aerial vehicle. Background technique [0002] In the process of modern agricultural production management, most links have been mechanized, but the control of crop diseases and insect pests has not yet been realized. There are problems such as unprofessional control, disorderly use of pesticides, large amount of pesticide residues, and serious environmental pollution. Although a small number of new self-propelled spraying machines have been used in recent years, they cannot meet the needs of crops in the middle and late stages of growth and control; manual spraying is labor-intensive and takes a long time, and the quality of work is poor. Evenly, the expected effect cannot be achieved, and the use of manpower to spray pesticides directly endangers the personal health of the workers, easily causing poisoning and even death, w...

Problems solved by technology

[0002] In the process of modern agricultural production management, most links are mechanized, but the control of crop diseases and insect pests has not yet been realized, and there are problems such as unprofessional control, disorderly use of pesticides, large amount of pesticide residues, and serious environmental pollution.

Although a small number of new self-propelled spraying machines have been used in recent years, they cannot meet the needs of crops in the middle and late stages of growth and control; manual spraying is labor-intensive and takes a long time, and the quality of work is poor. Evenly, the expected effect cannot be achieved, and the use of manpower to spray pesticides directly endangers the personal health of the workers, easily causing poisoning and even death, which seriously hinders the rapid development of modern agriculture. The spraying of low-volume pesticides is suitable for intelligent, high-efficiency, full-process, and low-cost new spraying equipment for farms and large-scale crops. The existing pesticide spraying devices for drones have poor spraying effects and short spraying distances. The problem, in addition to this, pesticide precipitation has its own rules, and the precipitation leads to uneven pesticide concentration after spraying from the sprinkler head
