Embodiment 1

[0025] refer to Figure 1 to Figure 2 , the body 1 is equipped with a power supply module, a control module, and a signal transceiver module, and drives the rotor 2 to rotate, which is the prior art and will not be repeated here.

[0026] A water tank 3 is installed on the body 1, a rotor 2 is arranged on the body 1, a centrifugal nozzle 12 is installed on the lower end of the rotor 2, and an air inlet is provided on the centrifugal nozzle 12, so as to prevent the medicine in the water tank 3 from being discharged when the centrifugal nozzle 2 is running. The liquid is sucked in through the U-shaped telescopic tube 6, and at least one telescopic U-shaped tube 6 is vertically arranged in the water tank 3 .

[0027] refer to figure 2 Specifically, the telescopic U-shaped tube 6 includes a U-shaped tube 61 adopting a U-shaped structure, a main tube 62 and a sub-tube 63. The specific connection method: the sub-tube 63 is slidably nested in the main tube 62, and the female tube 6...

Embodiment 2

[0038] On the basis of Embodiment 1, this embodiment is further set up as follows: the support frame 8, the connecting rod 9 and the suspension rod 10 all adopt a hollow structure, and the three are connected, and the connecting rod 9 is connected to the centrifugal nozzle 12 through the second hose 13. The air inlet is connected, and the bottom end of the boom 10 is flush with the bottom end of the floating plate 11 and communicated with the outside world.

[0039] Since the centrifugal nozzle 12 will form a negative pressure at the nozzle when it moves, in this embodiment, when the floating plate 11 is not in contact with the liquid surface of the paddy pond, the balance air pressure can be communicated with the outside world through the suspension rod 10 to replace The effect of the air inlet in embodiment 1; and when the floating plate 11 is in contact with the liquid surface of the paddy pond, under negative pressure, the suspender 10 can be drawn into the liquid in the pa...

Abstract

The invention discloses an anti-drift type ultra-low-altitude low-volume agricultural spray unmanned aerial vehicle, and relates to the technical field of agricultural unmanned aerial vehicles. The anti-drift type ultra-low-altitude low-volume agricultural spray unmanned aerial vehicle comprises a body, a water tank is arranged on the body, and at least one telescopic U-shaped pipe is vertically arranged in the water tank; one end of the telescopic U-shaped pipe extends to the bottom of the water tank; the other end of the telescopic U-shaped pipe extends to the outer side of the water tank, and communicates with the input end of a centrifugal sprayer through a first hose; the bottom end of the telescopic U-shaped pipe is fixedly connected with a connecting pipe; a suspension rod is fixedly connected to the bottom end of the connecting rod; and a floating plate is fixedly connected to the bottom end of the suspension rod. The anti-drift type ultra-low-altitude low-volume agricultural spray unmanned aerial vehicle has the outstanding characteristics that expansion and contraction of the U-shaped telescopic pipe are realized through cooperative design of the U-shaped telescopic pipeand a floater, and siphoning is realized through contraction motion of the U-shaped telescopic pipe, so that pesticide can be delivered to the centrifugal sprayer, siphoning of the U-shaped telescopicpipe in the water tank is triggered by the tension of liquid, and spraying of the unmanned aerial vehicle in a certain height is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural unmanned aerial vehicles, in particular to an anti-drift ultra-low altitude and low-volume agricultural spray unmanned aerial vehicle. Background technique [0002] In the prior art, when the agricultural drone is spraying, the liquid medicine sprayed by it will drift. For example {Wang Jihuan, Wang Xiu, et al. Analysis of the main factors affecting the drift of chemical pesticide spraying [J]. Chinese Journal of Agricultural Mechanics, 2016, 37(3):82-83} records that the drift of spray is mainly related to the droplet size and velocity , height, etc. Among them, the height of the fog droplets has a greater impact on the drift. When the distance between the UAV and the crops is small, the movement time of the droplets is very short and is less affected by the wind. Even small droplets, It can also reach the target, but when it is too low, there will be a striped effect, resulting in uneven d...
