Charged atomized spraying system allowing rotor drone to achieve wind-pesticide integration

Abstract

The invention discloses a charged atomized spraying system allowing a rotor drone to achieve pesticide integration and belongs to the field of crop protection drones. The charged atomized spraying system comprises the rotor drone and brushless membrane pesticide pumps, electronic regulators and atomizing sprayers which are sequentially serially connected through pesticide conveying pipes, a pesticide tank is fixed to the rotor drone, the atomizing sprayers are located pesticide raising preventing devices and located in the downward wind field areas of the rotor drone, and the pesticide raisingpreventing devices are arranged on the frame of the rotor drone. By the arrangement, the charged atomized spraying system has the advantages that the efficiency and precision requirements during drone pesticide application can be satisfied, most of the pesticide solution can act on crops to avoid pesticide solution waste, and the body of the drone can be prevented from being corroded by the pesticide solution.

Description

Technical field [0001] The invention belongs to the field of plant protection drones, and in particular, relates to a charged atomized spraying system used for rotor drones to form integrated wind and medicine. Background technique [0002] With the continuous advancement of agricultural planting and management technology, today's agriculture is gradually turning into digital agriculture, which can better guarantee the yield and quality of agricultural products. As a large agricultural country, my country's agricultural planting and management technology is continuously developing, and spray devices represented by drones are developing rapidly. [0003] During the spraying operation of the drone, the traditional operation mode is prone to the following problems. For example, the traditional operation mode of the plant protection drone is to spray the pesticide directly on the crops through the nozzle. This mode of operation Rough, it cannot meet the requirements for efficient and ...

Problems solved by technology

[0003] During the spraying operation of drones, the traditional operation mode is prone to the following problems. For example, the traditional operation mode of plant protection drones is to directly spread the agent on the crops through the nozzle to achieve spraying. This operation mode It is relatively rough and cannot meet the needs of efficient and precise pesticide application in the existing agricultural development process; secondly, the traditional sprinkler head of the UAV for plant protection is easy to form a downward umbrella-shaped three-dimensional working surface. Under the influence of height and terrain height changes, and plant height changes, it is easy to miss spraying and re-spraying; third, when plant protection drones are operated with traditional nozzles, they only rely on the gravity of the drops and the spraying settings of the nozzles. Affected by the inertia generated by the flight speed of the UAV, the natural wind force, the updraft, etc., it is easy to drift, diffuse and evaporate, resulting in the waste of liquid medicine or the occurrence of drug damage; Fourth, due to the unidirectional rotation of the UAV rotor The centrifugal force acts on the sprayed medicinal liquid, which is easy to cause the hoisting of the medicinal liquid. While causing the waste of medicinal liquid, the acidic and alkaline medicinal liquid will also cause corrosion to the body; During operation and due to the high dependence of the droplet settlement requirement on water during spraying, the droplet particles cannot be atomized, and the flight speed cannot be increased when taking into account the effect of spraying, resulting in low operating efficiency; There is no atomization effect during use, and it can only be achieved by increasing the proportion of the liquid medicine, and the increase in the proportion of the liquid medicine will lead to an increase in the load of the drone, resulting in an increase in the purchase cost of the drone, and high after-sales and maintenance costs.
