Multi-rotor unmanned pesticide application machine

Abstract

The invention provides a multi-rotor unmanned pesticide application machine which comprises a machine body assembly and a pesticide box assembly which are mounted on an undercarriage assembly, wherein a plurality of machine arm assemblies are mounted on the machine body assembly and are movably connected with insertion holes in the machine body assembly; clamp nuts are arranged at the combining parts; a propeller is connected with a motor in a clamping manner; a plurality of centrifugal tooth disks are rotationally mounted on the motor of each spray head assembly; a conical surface is arranged on the round base of each centrifugal tooth disk; a plurality of carving grooves arranged along a bus are formed in the inner side of each conical surface; a gasket is fixed in each centrifugal tooth disk; check valves are connected with liquid conveying pipes; the liquid conveying pipes penetrate through the center of the motor and the bases of the centrifugal tooth disks; a liquid conveying opening is formed in each liquid conveying pipe positioned above the corresponding gasket. The multi-rotor unmanned pesticide application machine provided by the invention has the benefits as follows: the liquid conveying system is simple, requirements for strength of the pesticide box are low, flow of liquid pesticide and size of fogdrop can be adjusted, and the carrying capacity of the whole machine is increased effectively; since the machine arms can be inserted and pulled out and the propeller can be rapidly disassembled, the difficulties that the whole machine is difficult to transport and replace during failure because of large size are effectively reduced.

Description

technical field [0001] The invention relates to the field of plant protection aircraft, in particular to a multi-rotor unmanned spraying machine. Background technique [0002] The plant protection pesticide applicator is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flying platform (fixed wing, single rotor, and multi-rotor), GPS flight control, and a spraying mechanism. Or GPS flight control to realize the spraying operation, which can spray chemicals, seeds, powder, etc., and the spraying process is sprayed through the nozzle. [0003] However, the current multi-rotor unmanned spraying machine has the following defects: [0004] (1) The pump pressure system has a complex structure and a large volume, and the water pump with an outlet pressure between 0Mpa and 8Mpa is not only large in size, but also relatively heavy, which increases the load on the drone, affects the flight du...
