[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the rotor UAV is assembled with the main support frame through the prefabricated plate. The telescopic rod is pulled vertically downward, and the arc plate moves downward with the disc. When the device is used, the adjustment spring is always in a stretched state, and the inner ball head of the ball head rod always fits and slides with the inner wall of the groove opened on the outer side of the arc plate.

The main bearing frame and the support frame are assembled as a whole through the threaded assembly method of the above components to form a landing frame that is easy to disassemble and assemble. When the agricultural plant protection UAV is used, it can be assembled as a whole after arriving at the use site, which is convenient for disassembly, assembly, storage and storage of the landing frame of the agricultural plant protection UAV;

[0015] 2. In the present invention, the straight plate is pressed downward, and the flexible spring is stretched. The medicine liquid box is placed in the area between the top of the carrier plate and the inner side of the folding block. The straight plate is released, and the straight plate is reset under the action of the flexible spring. At this time, the bottom end of the rubber plate is in contact with the top of the medicine liquid box, and the second air guide tube is fitted and assembled with the circular hole set on the top of the medicine liquid box to firmly clamp and limit the medicine liquid box.

[0016] 3. In the present invention, when the air pump device is started, air is blown into the cavity box through the connected pipe, and the air enters the second air duct through the first air duct. The air entering the second air duct forms two passages, one of which is a passage where the air enters the medicine liquid box through the through hole arranged at the bottom of the second air duct, and the discharge of the medicine liquid is promoted by the method of air blowing and pressurization, and the medicine liquid is pressurized and atomized and sprayed out through the fine holes opened in the liquid outlet tube. In the other passage, the air enters the end tube through the folded tube, the third air duct and the fourth air duct, and is exhausted through the dust-proof filter arranged inside the end tube. The device can disperse the atomized medicine liquid through air flow through four groups of symmetrically arranged first air duct, second air duct, rubber plate, folded tube, third air duct, fourth air duct, end tube and dust-proof filter, so as to improve the atomization degree of the medicine liquid.

[0057] A flexible buffer pad is fixedly provided on the top of the box plate 11. The rotor UAV is assembled with the main frame 1 through the prefabricated plate 4. The telescopic rod 15 is manually pulled vertically downward. The disc 16, the connecting rod 171, the arc plate 172, the first disc block 173 and the second disc block 174 are fixed structures. At this time, the arc plate 172 moves downward with the disc 16, and the sleeve 176 plays a role in limiting the horizontal sliding of the ball head rod 178. The first disc block 173 can limit the top of the inner ball head of the ball head rod 178, and the second disc block 174 can limit the bottom of the inner ball head of the ball head rod 178. When the device is in use, the adjustment spring 1772 is always in a stretched state, and the inner ball head of the ball head rod 178 is always in the groove opened on the outer side of the arc plate 172 The outer ball head of the ball head rod 178 first fits and touches the strip plate 141. At this time, the strip plate 141, the L-shaped plate 144, the connecting plate 145, the first hole plate 146 and the second hole plate 147 rotate circumferentially along the central axis of the sleeve rod 142 as a whole. The outer ball head of the ball head rod 178 contacts the bottom groove of the L-shaped plate 144 and continues to extend outward until the outer ball head of the ball head rod 178 touches the inner wall of the bottom groove of the L-shaped plate 144 to limit the position, forming an extended structure of the main frame 1, and the prefabricated plate 4 and the second hole plate 147 are threadedly assembled by external studs to form an assembly structure of the rotor UAV and the main frame 1.

[0058] The external studs are threadedly assembled to the anchor plate 217 and the first hole plate 146, and the main frame 1 and the support frame 2 are integrally assembled by the threaded assembly method of the above components.

[0059] The bottom plate of the air pump device 201 is fixed to the support plate 301, and the side of the straight plate 210 close to the liquid medicine tank is fixed to the support plate 301. The support frame 2 and the box frame 3 are fixed as a whole by the fixing method of the above components. Pull out the sliding plug set at the center of the top of the liquid medicine tank, and pour the liquid medicine into the liquid medicine tank. After the pouring is completed, reset the sliding plug and press the straight plate 210 downward. At this time, the flexible spring 212 is stretched, and the liquid medicine tank is placed in the area between the top of the support plate 301 and the inner side of the folding block 302, and release it.

When the elbow 310 is assembled and installed, the bottom pipe opening of the elbow 310 is inserted into the top of the first liquid guide pipe 308 and the top of the second liquid guide pipe 309. At this time, the inner wall of the first liquid guide pipe 308 is The inner walls of the second liquid guiding tube 309 are in contact with the silicone ring 311 provided on the outer side of the bottom of the curved tube 310, and the side plates provided on the first liquid guiding tube 308, the second liquid guiding tube 309 and the curved tube 310 are threadedly assembled through external studs to form a connected drainage pipeline structure. When the medical liquid flows inside the second liquid guiding tube 309, the curved tube 310 and the first liquid guiding tube 308, a better leak-proof sealing structure can be formed through the silicone ring 311.

[0060] When the air pump device 201 is started, air is blown into the cavity box 202 through the connected pipe, and the air enters the second air duct 204 through the first air duct 203, and the air entering the second air duct 204 forms two passages;

[0061] In one of the passages, air enters the medicine liquid tank through the through hole provided at the bottom of the second air guide tube 204, and the discharge of the medicine liquid is promoted by means of air pressure increase. The discharged medicine liquid enters the T-shaped tube 305 through the second liquid guide tube 309, the curved tube 310 and the first liquid guide tube 308, and the medicine liquid is pressurized and atomized and sprayed out through the fine hole provided in the liquid outlet tube 307;

[0062] In another passage, air enters the end tube 214 through the folded tube 206, the third air duct 207 and the fourth air duct 213, and is exhausted through the dust filter 215 provided inside the end tube 214. The device can disperse the atomized medicine liquid through the four groups of symmetrically arranged first air duct 203, second air duct 204, rubber plate 205, folded tube 206, third air duct 207, fourth air duct 213, end tube 214 and dust filter 215, so as to improve the atomization degree of the medicine liquid.
