Embodiment 1

[0048] see figure 1 and figure 2 , figure 1 A structural cross-sectional view of a solenoid valve used in a plant protection drone spraying system provided in the embodiment of the present application, figure 2 It is an exploded view of the structure of a solenoid valve used in the plant protection drone spraying system provided by the embodiment of the present application.

[0049] The spraying system of the plant protection drone can usually use a solenoid valve to control the opening and closing of the liquid channel. The solenoid valve is a valve device controlled by the principle of electromagnetic induction. The mechanical movement of the electromagnet is controlled by the current on and off of the electromagnetic coil to achieve the purpose of opening or closing the valve.

[0050] However, when the existing electromagnetic valve is in a working state, it needs to continuously energize the electromagnetic coil, which consumes a lot of power. When the plant protect...

Abstract

The invention provides an electromagnetic valve for a plant protection unmanned aerial vehicle, a spraying system and an air exhaust method. The electromagnetic valve comprises a valve element assembly, an adjusting assembly and an electromagnetic assembly. The adjusting assembly is arranged between the valve element assembly and the electromagnetic assembly. The adjusting assembly comprises a fixing shell, a driving gear, a rotating wheel, a connecting shaft and a first spring. The driving gear and the rotating wheel are arranged inside the fixing shell, the two ends of the rotating wheel abut against the driving gear and the valve element assembly correspondingly, and the two ends of the driving gear abut against the rotating wheel and the electromagnetic assembly correspondingly. One end of the connecting shaft abuts against the rotating wheel, and the other end of the connecting shaft abuts against the driving gear. The first spring sleeves the driving gear. The electromagnetic assembly is powered on and off, the adjusting assembly can be pushed to move so as to drive the valve element assembly to move, and therefore the electromagnetic valve can be located in an open or closedstate. The electromagnetic valve is low in power consumption and can be applied to the plant protection unmanned aerial vehicle spraying system, and the spraying operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of drones, and in particular relates to a solenoid valve, a spraying system and an exhaust method for plant protection drones. Background technique [0002] The plant protection drone is a kind of unmanned aircraft used for agricultural and forestry plant protection operations. By manipulating the plant protection drone through radio remote control equipment or its own program control device, it can realize the spraying operation of agricultural and forestry plants, thereby reducing labor costs and improving spraying efficiency. [0003] The spraying system of the plant protection drone usually includes a water pump connected to the medicine tank through a hose, multiple sprinklers connected to the water pump, and a solenoid valve arranged on the hose to control the opening and closing of the medicine liquid channel. The solenoid valve is a valve device controlled by the principle of electromagnetic inducti...
