Embodiment approach 1

[0013] Implementation mode 1, see Figure 1-3 .

[0014] An agricultural powder material sprayer, comprising a frame 1, four rotors 2, and rotor motors 3 respectively arranged under each rotor 2, the frame 1 is in the shape of a cage as a whole, and the upper part is a ring beam 11, the lower part is a circular basin bottom 12, and the middle part of the circular basin bottom 12 is provided with a through hole 16; four columns 13 connect the circular ring beam 11 and the circular basin bottom 12 as a whole and follow the circular ring beam 11 or the circle The circumference of the shaped basin bottom 12 is evenly distributed, the upper end of each column 13 is hinged to one end of the first cylinder 4, the lower end of each column 13 is hinged to one end of the second cylinder 5, and the other end of the first cylinder 4 is fixed to the rotor motor 3 , the motor shafts of the four rotor motors 3 are respectively fixed to 4 and the rotor 2, the opposite two rotors have the sam...

Embodiment approach 2

[0016] Implementation mode 2, see Figure 1-3 .

[0017] An agricultural liquid material sprinkler, the other is the same as Embodiment 1, the difference is that the solenoid valve 83 is connected to the nozzle 10, the landing gear 9 includes a dovetail-shaped landing gear seat 91 with the opening downward, and a first hinged joint at one end and the middle part of the dovetail groove. Three cylinders 94, the slide block 92 that the two ends of the dovetail groove are matched respectively, the first support 93 and the second support 95 that one end is respectively hinged with two slide blocks 92, the middle part of the first support 93 and the second support 95 is hinged, the third The other end of cylinder 94 is hinged with the upper section of first support 93 or second support 95, and the other end of two first supports 93 and two second supports 95 is connected by connecting rod 96 respectively, and the air outlet of miniature air compressor 7 It communicates with the cyl...

Embodiment approach 3

[0020] Implementation mode 3, see Figure 1-3 .

[0021] Others are the same as Embodiment 2, except that the outer surfaces of the container 8 and the sealing cover 81 are covered with solar panels. The solar panel is connected to the battery 6 . Since pesticides and fertilizers are mostly sprayed on sunny days, the electric energy converted by solar panels can be stored in batteries to prolong flight time and reflect the concept of green environmental protection.

Abstract

The invention provides an agricultural sprayer including a rack and four rotors. The overall rack is in a cage-like shape; four rotors are articulated on the rack by two cylinders, two opposite rotors have the same direction of rotation, and two adjacent rotors have opposite rotational direction; a battery, a mini air compressor and a landing gear are fixedly arranged outside the rack; a container is arranged in the rack, the lower part of the container is provided with a discharge port, the discharge port is connected with a solenoid valve, the upper part of the container is provided with a seal cover; the battery provides power for rotor motors, a micro inflator and solenoid valve; and the outlet of the micro inflator is in communication with the cylinder bodies and the container. Compared with the prior art, the invention has the following characteristics: higher stability than other aircraft, strong wind resistance, flexible attitude, fast response, capability of hedgehopping, large carrying capacity, and splicing of discharge port at the bottom of the container with different nozzles to accommodate liquid or powder material spray according to different needs of people.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a small agricultural spraying unmanned aerial vehicle used in the agricultural field. Background technique [0002] Quadcopter is a kind of micro-aircraft, and it is also a kind of intelligent robot. It was originally made by aviation enthusiasts. Later, many automation manufacturers found that it can be used for multiple purposes and actively participated in the development. It uses four rotors as flight engines to fly in the air. It is small in size, light in weight, suitable for carrying and use, and has the ability of autonomous navigation and flight. [0003] People spray pesticides and fertilizers on crops manually, which not only makes laborers very tired but also wastes a lot of time, greatly reducing work efficiency. If the common implements for spraying pesticides and chemical fertilizers are changed to aircrafts, the laborers will not only reduce the burden on their bodie...
