Unmanned aerial vehicle for plant protection

Abstract

The invention discloses an unmanned aerial vehicle for plant protection. The unmanned aerial vehicle comprises a rack, wherein a center plate is firmly connected to the top of the rack; multiple machine arms are uniformly distributed on sides of the center plate; a rotor driven by a motor is disposed on the front end of each machine arm; a water tank is firmly connected to the bottom of the center plate; an outlet of the water tank is connected to an inlet of a water pump by a pipeline; the water pump is fixed on a horizontal rod which is located at the middle part of the rack; spraying rods which extend to the left side and the right side are disposed at the middle part of the rack; a spraying nozzle is disposed on each spraying rod; an outlet of the water pump communicates with each spraying nozzle by multi-way joints and pipelines; landing rods are disposed on the left side and the right side of the bottom of the rack respectively; a storage battery is fixed on the top face of the center plate; and the storage battery is electrically connected to the water pump and the motor which drives the rotors. The center plate and the water tank sandwich the single rod for integral fastening. The unmanned aerial vehicle disclosed by the invention has the advantages that the structure is compact and firm; because of a damping sponge cushion, the spraying rods are prevented from shaking and then causing unstable flight of the whole machine, so that flight stability can be ensured.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a plant protection unmanned aerial vehicle. Background technique [0002] Plant protection drones, unmanned aircraft used for agricultural and forestry plant protection operations, realize spraying operations through ground remote control or GPS flight control, and can spray chemicals, seeds, powders, etc. The plant protection UAV has low operating height, less drift, can hover in the air, does not need 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, high control effect, and remote control operation , Spraying operators avoid the danger of exposure to pesticides, improve the safety of spraying operations and many other advantages. [0003] Stable flight is the most basic and important requirement in the manufacturing process of UAVs. The existing UAVs are developing tow...

Problems solved by technology

[0003] Stable flight is the most basic and important requirement in the manufacturing process of UAVs. The existing UAVs are developing towards lightweight. The large-scale application of carbon fiber materials can reduce the weight of the whole machine without affecting the firmness of the connection. Extend the flight time to a certain extent, but reduce the weight without changing the structure of the whole machine, which will lead to unstable flight and body shaking. Under normal circumstances, it is easier to resonate with the water pump and cause vibration, resulting in unstable flight and affecting the spraying effect
