Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a liquid medicine spraying device for unmanned aerial vehicles. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an onboard computer. Drones can be divided into military and civilian applications according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft, while in the civilian application area, drones + industry applications are the real rigid demand for drones. The application of drones in civilian fields such as aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, observing wild animals, photographing infectious diseases, surveying and mapping, news reporting, power inspections, disaster relief, filming, creating romance, etc. has greatly expanded the use of drones themselves.

[0003] After searching, the patent publication number CN218229419U discloses a patent named "A kind of liquid atomizing spraying device for crop protection drones". The technical problem to be solved is that the nozzle is usually fixed and can only spray in a specified direction, which reduces the spraying range of the device. When adding medicine to the device, it needs to be mixed manually, and the liquid medicine is prone to uneven mixing. Through the mutual cooperation between the rotating rod, motor, movable frame, incomplete gear, slider, slide groove, sleeve, rack and movable rod, the device can control the rotation of the incomplete gear to drive the movable frame to move back and forth when spraying medicine, so as to drive the two sets of spray rods to swing and spray continuously, thereby increasing the spraying range of the device and improving the spraying effect of the device; but there are still the following disadvantages that need to be solved: there will be wind formed by air flow in the natural environment, which is easy to cause the liquid medicine sprayed on the crops to deviate, thereby causing the crops to be sprayed unevenly with the liquid medicine.
