Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and particularly relates to a Mikania micrantha positioning spraying device for unmanned aerial vehicles. Background Technique

[0002] Mikania micrantha is a perennial herbaceous or woody vine of the genus Mikania in the Asteraceae family, and is an alien invasive species known as the "plant killer". It emits an allelochemical substance that causes other surrounding plants to wither gradually. It often climbs on the trunks and crowns of other plants and quickly forms a whole-plant covering trend, destroying the photosynthesis of surrounding plants and finally strangling them.

[0003] With the development of unmanned aerial vehicle technology, in order to improve work efficiency, staff usually adopt the method of using unmanned aerial vehicles to spray pesticides to remove Mikania micrantha. Most of the nozzles carried by common plant protection unmanned aerial vehicles are in a fixed state, with fixed spraying amplitude and spraying angle. When spraying pesticides on Mikania micrantha, the pesticides may be sprayed on nearby plants at the same time, causing damage to the ecological environment. In order to adjust the spraying amplitude and spraying angle of the unmanned aerial vehicle and avoid damaging other nearby plants when spraying pesticides on Mikania micrantha, we propose a Mikania micrantha positioning spraying device for unmanned aerial vehicles.

The spraying assembly includes a second motor 19, the second motor 19 is fixedly installed on the inner wall of the mounting frame 5, the output end of the second motor 19 rotates through the mounting frame 5, and the output end of the second motor 19 is fixedly connected to a rotating frame 20.

[0020] A plurality of groups of delivery pipes 15 are fixedly communicated with the side wall of the transfer box 13, one end of the delivery pipe 15 away from the transfer box 13 is fixedly communicated with a hose 18, and one end of the hose 18 away from the delivery pipe 15 is fixedly communicated with the top of the nozzle 22.

[0021] When the device is used, first inject pesticides into the medicine storage tank 4, then control the UAV to fly to the growth position of Mikania micrantha. The pesticides flow into the transfer box 13 through the connecting pipe 9 and the medicine delivery pipe 10 in sequence, and then are injected into the spraying assembly through the delivery pipe 15 and the hose 18. Adjust the angle of the spraying assembly so that its direction is aligned with Mikania micrantha and then spray the pesticides, which can prevent damage to other surrounding plants during the process of spraying pesticides on Mikania micrantha and protect the ecological environment.

[0022] The spraying assembly further includes a first motor 16. The first motor 16 is fixedly installed on the side wall of the rotating frame 20. The output end of the first motor 16 rotatably penetrates through the rotating frame 20. The output end of the first motor 16 is fixedly connected with a mounting plate 21. One end of the mounting plate 21 away from the first motor 16 is rotatably connected with the side wall of the rotating frame 20. A spray head 22 is fixedly penetrated through the mounting plate 21.

[0023] When the second motor 19 starts to drive the rotating frame 20 to rotate, the spray head 22 rotates. When the first motor 16 starts to drive the mounting plate 21 to rotate, the spray head 22 rotates. With the cooperation of the second motor 19 and the first motor 16, the angle of the spray head 22 can be flexibly adjusted, and the pesticide can be accurately sprayed to the designated position.

[0025] After the spraying assembly adjusts the angle, control the cylinder 11 to drive the pressing plate 12 to descend. Then the pesticide in the medicine storage tank 4 is sprayed out from the spray head 22 along the pipeline under the action of pressure. Adjusting the descending speed of the pressing plate 12 can change the pressure received by the pesticide, so as to adjust the spraying range.

[0026] A camera 2 is fixedly installed at the left end of the UAV body 1. A searchlight 8 is fixedly installed at the bottom of the transfer box 13.

The second motor 19 is started to drive the rotating frame 20 to rotate, so that the nozzle 22 rotates, and the first motor 16 is started to drive the mounting plate 21 to rotate, so that the nozzle 22 rotates. Under the cooperation of the second motor 19 and the first motor 16, the angle of the nozzle 22 can be flexibly adjusted so that the spraying direction is aimed at Mikania. After the spraying component adjusts the angle, the control cylinder 11 drives the pressing plate 12 to descend, and the pesticide in the medicine storage box 4 flows into the transfer box 13 through the connecting pipe 9 and the drug delivery pipe 10 in turn, and then is sprayed out from the nozzle 22 through the delivery pipe 15 and the hose 18, which can prevent other plants around from being damaged during the spraying of pesticides on Mikania, thereby protecting the ecological environment. Adjusting the descending speed of the pressing plate 12 can change the pressure received by the pesticide, thereby adjusting the spraying amplitude.
