Electrostatic spraying type unmanned helicopter pesticide applying system

Abstract

The invention discloses an electrostatic spraying type unmanned helicopter pesticide applying system. The system comprises an unmanned helicopter having a landing gear, a supporting frame, a storage battery, a high voltage electrostatic generator, an electric diaphragm pump, a pesticide box and two sets of electrostatic spraying devices, wherein the supporting frame and the landing gear are fixed; the storage battery, the high voltage electrostatic generator, the electric diaphragm pump and the pesticide box are fixed on the supporting frame; the electrostatic spraying devices are symmetrically arranged on both sides of the unmanned helicopter; and a liquid outlet of the pesticide box is communicated with a liquid inlet of the electric diaphragm pump, and a liquid outlet of the electric diaphragm pump is communicated with the liquid inlets of the electrostatic spraying devices by a tee joint respectively. The system has the advantages that the size of the sprayed charged droplets is quite small, so the droplets are high in deposition effect and uniformly distributed, in particularly, the droplets can be attached to the back surfaces of leaves of plants, the effective utilization rate of pesticide is guaranteed and the drift loss of pesticide is lowered; and the spraying amount can be remotely controlled, so the spraying amount of the system can be changed along with the change of the flying speed.

Description

technical field [0001] The invention relates to the equipment technology of agricultural aviation plant protection machinery, in particular to a remote-controlled unmanned helicopter system that uses an electrostatic spray structure to apply pesticides, so as to increase the adhesion of mist to crops and improve the efficiency of pesticide application. Background technique [0002] Aerial spraying of pesticides can be widely used in the prevention and control of diseases, insect pests and weeds of forestry and field crops. Especially when sudden disasters are approaching, aerial spraying of pesticides has a convenient and fast effect that cannot be replaced by any other machine tool. The unmanned remote control helicopter has many advantages such as low operating height, less drift, hovering in the air, no need for a special take-off and landing airport, and the downward airflow generated by the rotor helps to increase the penetration of the fog flow on the crops and has a hi...

Problems solved by technology

[0004] Purpose of the invention: In order to overcome the current situation of poor droplet deposition effect and invariable spray volume existing in the existing drone spraying device, the present invention provides a remote-controlled unmanned helicopter system that uses an electrostatic spray structure for spraying. The particle size of the final charged droplets is small, the deposition effect is good, and the distribution is uniform, especially on the back of the plant leaves, the droplets can also be attached to ensure the effective utilization of pesticides and reduce the drift loss of pesticides; and the spray volume can also be set Adjustable structure, so that the amount of spray produced by the system can change with the change of flight speed
