Description

Technical Field

[0001] This utility model relates to the field of drone spraying, specifically a drone that is easy to disassemble and assemble and can spray precisely. Background Technology

[0002] In agricultural planting, pesticides need to be sprayed on crops. To ensure even spraying, drones are often used for aerial spraying. Drone spraying mainly utilizes drones equipped with pesticide tanks and nozzles. Ground personnel remotely control the drones to change their direction. Agricultural drones are used for irrigation and pesticide spraying on crops. A search revealed a multi-rotor agricultural drone with application number CN202220552566.5, which describes a drone with a quick-assembly spraying structure. It includes a central control unit, an arm, and a rotor. The arm is connected to one side of the central control unit, and the central control unit is responsible for receiving commands and controlling the drone's operation. A rotor is installed at one end of the arm, and the rotor is responsible for taking off. When the locking block is engaged and fixed in the slot, it will drive the connecting block to connect with the fixing block, thereby assembling the spray pipe at the bottom of the fixing pipe, which facilitates quick assembly of the spray pipe. When the rotating rod rotates, it will drive the stirring blade to rotate. At this time, the stirring blade will agitate the pesticide in the storage tank, which can make the pesticide more thoroughly mixed and prevent pesticide sedimentation.

[0003] However, the above description still has the following defects in actual use: the spraying drone solves the problem of spray pipe installation, but the stirring blade will affect the structure of extracting pesticide liquid in actual use, and the spraying structure cannot be installed and disassembled with the drone. At the same time, the spraying range cannot be adjusted, so the accuracy of the spraying process cannot be improved. Therefore, it is necessary to design a practical, easy-to-disassemble and assemble drone that can spray accurately. Utility Model Content

[0029] Please see Figure 4 The installation component 2 includes a mounting base 21 installed at the bottom center of the body 1. The mounting base 21 has slots 22 on both ends of its edges. The inner walls of the two slots 22 are provided with connecting shafts 23. The surfaces of the two connecting shafts 23 are fitted with L-shaped limiting plates 24. The inner walls of the opposite side of the two L-shaped limiting plates 24 are connected to the side of the water storage tank 25. The two ends of the two L-shaped limiting plates 24 have slots 26. The inner walls of the two sets of slots 26 are engaged with two limiting strips 27. The surfaces of the two ends of the two limiting strips 27 have limiting holes 28. The inner walls of the two sets of limiting holes 28 are threadedly connected to the positioning holes 210 on one side of the inner walls of the two sets of slots 26 through limiting pins 29.

[0030] In practical use: Rotate the two L-shaped limiting plates 24 on the surface of the connecting shaft 23 on the inner wall of the two slots 22 until the inner wall of the two L-shaped limiting plates 24 is engaged with the surface of the water storage tank 25. Engage the two limiting strips 27 with the inner wall of the two sets of slots 26, and insert the two sets of limiting pins 29 into the two sets of limiting holes 28 and positioning holes 210, thereby completing the fixation of the two limiting strips 27 and the L-shaped limiting plates 24, so as to facilitate the installation and disassembly of the water storage tank 25. Engage the connecting pipe 311 at the top of the spray pipe 33 with the water outlet pipe 211, and use the tightening ring to install and disassemble the two. Engage the elastic clips 31 at the bottom of the two connecting parts 32 with the surface of the support frame 12, thereby facilitating the installation and disassembly of the spray structure.

[0031] Please see Figure 5The spray assembly 3 is adjusted. The spray assembly 3 includes two elastic clips 31 mounted on the surface of the support frame 12. The tops of the two elastic clips 31 are fixedly connected to the bottoms of both ends of the spray pipe 33 via connectors 32. The surfaces of both ends of the spray pipe 33 are fixedly connected to two telescopic tubes 35 via mounting rings 34. The other end of each of the two telescopic tubes 35 is provided with an auxiliary ring 36. The sides of the surfaces of the two auxiliary rings 36 are provided with limiting rods 37.

[0032] In practical use: the two auxiliary rings 36 drive the two limiting rods 37 to move within the inner wall of the through hole 312 on the side of the two mounting rings 34, while simultaneously driving the two telescopic tubes 35 to stretch until they reach the appropriate position. Then, the locking knob 39 is threadedly connected to the annular groove on the edge of the inner wall of the through hole 312, which facilitates the limiting rods 37 and the mounting rings 34 to be limited and fixed, thus completing the limiting of the telescopic tubes 35 after adjustment. The pump body draws the liquid from the water storage tank 25, which enters the spray pipe 33 and the telescopic tube 35 through the outlet pipe 211 and the connecting pipe 311. Then, it cooperates with several spray heads 310 to perform spraying operations, so as to improve the spraying range and spraying accuracy.

[0043] In practical use: the support rod 1102 is threaded to the frame rod 1101, which facilitates the installation and replacement of the propeller blade 1103 and the frame rod 1101, and realizes the disassembly and assembly of the wing 11 structure.

[0044] In use, rotate the two L-shaped limiting plates 24 on the surface of the connecting shaft 23 on the inner wall of the two slots 22 until the inner wall of the two L-shaped limiting plates 24 engages with the surface of the water storage tank 25. Engage the two limiting strips 27 with the inner wall of the two sets of slots 26, and insert the two sets of limiting pins 29 into the two sets of limiting holes 28 and positioning holes 210 to fix the two limiting strips 27 and L-shaped limiting plates 24, so as to facilitate the installation and disassembly of the water storage tank 25. Engage the connecting pipe 311 at the top of the spray pipe 33 with the water outlet pipe 211, and use the tightening ring to install and disassemble them. Engage the elastic clips 31 at the bottom of the two connecting parts 32 with the surface of the support frame 12 to facilitate the spraying. The spray structure is installed and disassembled; two auxiliary rings 36 drive two limiting rods 37 to move within the inner wall of the through hole 312 on the side of the two mounting rings 34, while simultaneously driving the two telescopic tubes 35 to stretch until they reach the appropriate position. Then, the locking knob 39 is threaded into the annular groove on the edge of the inner wall of the through hole 312 to facilitate the limiting rods 37 and the mounting rings 34 to be fixed in place. This completes the limiting of the telescopic tubes 35 after adjustment. The pump body draws the liquid from the water storage tank 25, which enters the spray pipe 33 and the telescopic tube 35 through the outlet pipe 211 and the connecting pipe 311. Then, it cooperates with several spray heads 310 to perform spraying operations, so as to improve the spraying range and spraying accuracy.
