[0031] In this embodiment, the personnel can first pull the movable column 105 outward to make it slide outward inside the connecting piece 102, while driving the reset spring 106 to extend, and then place the drone body 1 on the top of the medicine barrel 103, and press down the drone body 1 to drive the connecting column 101 to be embedded in the inside of the connecting groove 104. When the connecting column 101 is embedded to a certain extent, the personnel can loosen the movable column 105 to reset the reset spring 106, so that while resetting, it can drive the movable column 105 to slide inward and embed into the inside of the positioning groove 107, and then the personnel can turn the bolt 108, so that it is embedded in the inside of the threaded hole 109, thereby fixing the drone body 1 and the medicine barrel 103, and the arrangement of the connecting piece 102 and the bolt 108 structure not only simplifies the separation and installation process of the drone body 1 and the medicine barrel 103, but also makes it easier for personnel to complete the loading and unloading operations, reducing the operation time and labor intensity. At the same time, since the drone body 1 and the medicine barrel 103 can be handled independently, when the equipment fails, only the damaged part needs to be replaced instead of the entire system, which not only reduces the waste caused by equipment damage, but also shortens the equipment downtime and improves the equipment utilization efficiency.

[0032] Example 2, as Figures 1 to 4 As shown, a motor 201 is fixedly installed on the top of the rotating rod 2, a plurality of blades 202 are fixedly installed on the outer surface of the rotating rod 2, support columns 204 are fixedly installed at the center of both sides of the rotating rod 2, and scrapers 205 are fixedly installed on the outer sides of the two support columns 204. A chute 203 is opened at the center of the inner wall of the medicine barrel 103, and the outer surfaces of the two scrapers 205 are slidably connected to the inner surface of the chute 203. A first water outlet pipe 206 is fixedly embedded on the front side of the bottom of the medicine barrel 103, and a first water outlet pipe 206 is fixedly embedded on the front side of the bottom of the medicine barrel 103. A pump 207 is fixedly installed at the other end of a water outlet pipe 206, the top of the pump 207 is fixedly installed at the bottom of the medicine barrel 103, a second water outlet pipe 208 is fixedly installed on the left side of the pump 207, a conveying rack 209 is fixedly installed at the other end of the second water outlet pipe 208, the outer surface of the conveying rack 209 is fixedly installed at the bottom of the medicine barrel 103, a water inlet pipe 211 is fixedly installed on the top rear side of the medicine barrel 103, and a plurality of nozzles 210 are fixedly installed at the bottom of the conveying rack 209.

This design ensures smooth transportation and efficient spraying of the liquid medicine, and is suitable for scenarios that require continuous spraying, such as plant protection operations.

When the rotating rod 2 is rotating, it can drive the scraper 205 to slide in a circle inside the chute 203 through the support column 204, and then the scraper 205 scrapes the inner wall of the medicine barrel 103 to prevent the medicine powder from adhering to the inner wall of the medicine barrel 103, resulting in insufficient mixing. When the liquid medicine is stirred, personnel can start the pump 207 through the power supply system of the pump 207, so that when it is running, it can extract the inside of the medicine barrel 103 through the first water outlet pipe 206. The liquid medicine enters the interior of the pump 207, and is then transported by the pump 207, so that the liquid medicine enters the interior of the conveying rack 209 through the second water outlet pipe 208, and is transported again by the conveying rack 209, so that the liquid medicine enters the interior of the nozzle 210, and is sprayed out through the nozzle 210 to spray the plant protection. Moreover, the arrangement of the rotating rod 2 and the pump 207 structure not only effectively combines the stirring and scraping functions, ensures that the mixing of the powder and the clean water is more uniform, and prevents the powder from adhering to the inner wall of the medicine barrel 103, thereby improving the mixing effect and spraying quality of the liquid medicine, but also the pump 207 transports the stirred liquid medicine to the interior of the nozzle 210, and then sprays it through the nozzle 210.
