Plant protection unmanned aerial vehicle with spray nozzles easy and convenient to replace

Abstract

The invention belongs to the field of unmanned aerial vehicles, and discloses a plant protection unmanned aerial vehicle with spray nozzles easy and convenient to replace. The plant protection unmanned aerial vehicle comprises installing racks which are symmetrically fixed to the bottom of an unmanned aerial vehicle body, fixing rods are fixed to the opposite sides of the installing racks, a liquid storage box is fixed to the opposite ends of the fixing rods, an installing rod is fixed to one side of each installing rack, an installing plate is detachably and fixedly installed on the installing rod and in the length direction of the installing rod through a fixing mechanism, and the spray nozzles are fixed to the bottom of the installing plate. The installing rod, a pressing rod, a guidingpillar, the installing plate, a limiting pillar, the spray nozzles, liquid guiding branched pipes, a liquid guiding main pipe, a threaded pillar, a knob and a clockwise and anticlockwise rotation motor are arranged, in this way, the spray nozzles can be replaced without tools for detaching screws, and when the number of the damaged spray nozzles is large, the effect of replacement is better; in addition, a user can select a manual or electric detaching mode according to needs.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a plant protection unmanned aerial vehicle with easy replacement of nozzles. Background technique [0002] Unmanned plant protection aircraft, as the name suggests, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flying platform, GPS flight control, and spraying mechanism. The spraying operation is realized through ground remote control or GPS flight control. , can spray medicine, seeds, powder and so on. After the nozzles of the current unmanned plant protection machines are damaged, especially when the number of damages is large, it is often necessary to manually disassemble and replace the damaged nozzles one by one with a tool for removing screws. The replacement process is cumbersome and laborious. A good use effect. Therefore, there is an urgent need for a pla...
