Description

Technical field [0001] The invention relates to the field of agricultural drone devices, in particular to a six-rotor spray drone for spraying citrus forests. Background technique [0002] The traditional spraying method for citrus groves is to hold a spray nozzle on the ground to spray the trees. This method is low in efficiency and is greatly affected by the terrain. Compared with taller trees, there may be insufficient pressure and spraying. The pesticides released can cause harm to the human body and even endanger life. [0003] Although drones are now used in the agricultural field to a certain extent, there are still certain shortcomings in the process of use: For large citrus trees with lush branches and leaves, due to the number of branches in the process of spraying pesticides , The liquid medicine will be sprayed directly on the upper surface of the blade under the action of the air pressure of the rotor, and only the spray on the upper surface of the blade can be achiev...

Problems solved by technology

[0002] The traditional way of spraying citrus groves is that people hold the nozzle on the ground to spray the trees. This method is inefficient and is greatly affected by the terrain. Compared with taller trees, there may be insufficient pressure and the spraying cannot be done. The pesticides released will cause harm to the human body, even life-threatening

[0003] Although drones have been used in the agricultural field to a certain extent, there are still certain defects in the use process: for large citrus trees with luxuriant branches and leaves, due to the large number of layers of branches, it is difficult to spray pesticides during the process of spraying pesticides. , the liquid medicine will be sprayed directly to the upper surface of the blade under the action of rotor air pressure, only the spraying on the upper surface of the blade can be realized

[0004] For example: the plant protection unmanned aerial vehicle disclosed in CN 106043704 A adopts a six-rotor unmanned aerial vehicle, but the nozzle of this unmanned aerial vehicle adopts the traditional nozzle spraying effect is not ideal, and there are only two nozzles, which are installed at the two ends of the spray rod , which greatly limits the scope of spraying, which in turn affects the spraying efficiency
