[0002] In the process of modern agricultural production management, most links have achieved mechanized operation, while the prevention and control of crop diseases and pests have not been realized, and there are problems such as unprofessional prevention and control, chaotic use of pesticides, large amounts of pesticide residues, and serious environmental pollution. The existing pesticide spraying methods mainly include manual spraying and drone spraying. Among them, manual spraying is carried out by workers manually spraying pesticides. This method consumes a lot of time and physical strength of the staff. Drone spraying is widely welcomed because of its fast spraying time, high efficiency and saving the physical strength of the staff. When the spraying drone sprays pesticides, it sprays pesticides through a spraying rod connected to a medicine tank.

[0003] The spraying nozzles of the existing spraying drones are arranged downward. Moreover, because there is a lot of dust and floating impurities in the air in the farmland, as the spraying drone flies to the operation farmland, the floating impurities and dust in the air will enter the spraying nozzles, and then block the spraying nozzles, affecting the use. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a multifunctional agricultural drone.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A multifunctional agricultural drone includes a drone body. In the middle of the bottom end of the drone body, there is a medicine tank. A support plate is fixed at the bottom end of the medicine tank. A receiving groove is opened in the support plate. A driving mechanism is arranged in the receiving groove. A plurality of connecting plates are obliquely arranged at the bottom of the support plate. Through holes are opened in the connecting plates. The receiving groove is communicated with the through holes. A rotating mechanism is arranged in the through holes. The driving mechanism is connected with a plurality of the rotating mechanisms. The output end of the rotating mechanism penetrates to the bottom end of the connecting plate and is connected with a shielding plate. The middle of the bottom end of the medicine tank is communicated with an infusion tube. The infusion tube is located above the support plate. A plurality of connecting tubes are evenly communicated at the bottom end of the infusion tube. The bottom output end of the connecting tube penetrates to the support plate and is connected with a spraying nozzle.

The bottom output end of the connecting pipe 4 penetrates to the support plate 6 and is connected to a spraying nozzle 5. The shielding plate 8 is located below the spraying nozzle 5 and blocks the bottom output end of the spraying nozzle 5. A sponge layer is provided on the top of the shielding plate 8. A dust-proof groove 18 is formed at the center of the top of the shielding plate 8. The top opening of the dust-proof groove 18 penetrates through the sponge layer. The dust-proof groove 18 matches the opening of the spraying nozzle 5. An installation groove 20 is formed on the side of the shielding plate 8. The installation groove 20 is communicated with the dust-proof groove 18. A connecting film 21 is placed inside the installation groove 20. A fixing component matching the connecting film 21 is provided in the installation groove 20. Through the setting of the shielding plate 8, the shielding plate 8 matches the output end of the spraying nozzle 5. The dust-proof groove 18 on the top of the shielding plate 8 closely adheres to the opening of the spraying nozzle 5, which can protect and block it, and prevent dust and impurities from entering the spraying nozzle 5 through the opening of the spraying nozzle 5 and causing impurity blockage.

[0027] Refer to Figure 4, the driving mechanism includes two support seats 9 fixedly connected to the inner bottom of the receiving groove. A rotating rod 10 is rotatably mounted on the two support seats 9. One end of the rotating rod 10 penetrates outside one of the support seats 9 and is connected to a motor 11. The motor 11 is fixed on one of the support seats 9. A number of first bevel gears 12 are evenly arranged on the outer surface of the rotating rod 10. A number of rotating shafts are rotatably connected to the inner wall of the receiving groove. A driving pulley 14 and a second bevel gear 13 are connected to the rotating shafts. The second bevel gear 13 meshes with the first bevel gear 12. Through the setting of the driving mechanism and the rotating mechanism, when the spraying nozzle 5 needs to perform operations, the driving mechanism operates to drive the rotating mechanism and the shielding plate 8 to rotate, so that the shielding plate 8 moves away from the spraying nozzle 5, exposing the spraying nozzle 5, facilitating the spraying of pesticides on crops. When the spraying nozzle 5 finishes working, it drives the shielding plate 8 to rotate back to block the output end of the spraying nozzle 5. At this time, the dust-proof groove 18 at the top of the shielding plate 8 closely adheres to the output end of the spraying nozzle 5, which can protect and block it, preventing dust and impurities from entering through the opening of the spraying nozzle 5.

[0028] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the rotating mechanism includes a fixed rod 17 rotatably connected in the through hole. One end of the fixed rod 17 is provided with a driven pulley 16. A belt 15 is wound around the driven pulley 16. The other end of the belt 15 penetrates into the receiving groove and is wound around the driving pulley 14. The other end of the fixed rod 17 penetrates outside the connecting plate 7 and is fixedly connected to the shielding plate 8. Through the setting of the driving mechanism and the rotating mechanism, when the spraying nozzle 5 needs to perform operations, the driving mechanism operates to drive the rotating mechanism and the shielding plate 8 to rotate, so that the shielding plate 8 moves away from the spraying nozzle 5, exposing the spraying nozzle 5, facilitating the spraying of pesticides on crops. When the spraying nozzle 5 finishes working, it drives the shielding plate 8 to rotate back to block the output end of the spraying nozzle 5. At this time, the dust-proof groove 18 at the top of the shielding plate 8 closely adheres to the output end of the spraying nozzle 5, which can protect and block it, preventing dust and impurities from entering through the opening of the spraying nozzle 5.

[0029] Refer to Figure 5 and Figure 6, the fixing component includes a liquid absorption pad 19 fixed to the top of the connection film 21. The liquid absorption pad 19 is located in the middle of the top of the installation groove 20. The top end of the liquid absorption pad 19 penetrates into the dust-proof groove 18. The fixing component further includes an annular backing plate 23 slidably connected in the installation groove 20. The bottom end of the annular backing plate 23 is pressed against the top side of the connection film 21. A threaded rod 22 is threadedly connected to the top of the shielding plate 8. A threaded hole matching the threaded rod 22 is opened at the top of the shielding plate 8. The bottom end of the threaded rod 22 penetrates into the installation groove 20 and is movably connected to the top of the annular backing plate 23. A plug is provided at the top of the threaded rod 22 penetrating through the shielding plate 8. A plurality of plug holes matching the plug are opened at the top of the shielding plate 8. Through the setting of the fixing component, the fixing component can replace the liquid absorption pad 19, avoiding that when spraying different pesticides, different liquid medicines dripping on the liquid absorption pad 19 will infect the output end of the medicine spraying nozzle 5, thereby affecting the spraying effect of the pesticides.

[0030] During use, start the unmanned aerial vehicle body 1 to fly above the farmland area where spraying is required (at this time, the dust-proof groove 18 at the top of the shielding plate 8 is always closely attached to the opening of the medicine spraying nozzle 5 to protect and block it, preventing dust and impurities from entering the medicine spraying nozzle 5 through the opening of the medicine spraying nozzle 5 and causing impurity blockage). When the unmanned aerial vehicle body 1 flies above the crops and spraying operation is required, the driving mechanism can be started to drive the rotating mechanism and the shielding plate 8 to rotate, so that the shielding plate 8 leaves the medicine spraying nozzle 5, exposing the medicine spraying nozzle 5, facilitating the spraying of pesticides on the crops. That is, start the motor 11, the motor 11 drives the driving rotating rod 10 and a plurality of first bevel gears 12 to rotate. The rotation of a plurality of first bevel gears 12 drives a plurality of second bevel gears 13 meshing with them to rotate. A plurality of second bevel gears 13 drive the connected driving belt pulleys 14 to rotate through the rotating shafts. When the driving belt pulleys 14 rotate, they drive the belt 15 to rotate. The belt 15 drives the driven belt pulley 16 and the fixed rods 17 to rotate. The simultaneous rotation of a plurality of fixed rods 17 can drive a plurality of shielding plates 8 to rotate simultaneously. At the same time, when the shielding plates 8 rotate, all the medicine spraying nozzles 5 will be exposed simultaneously. At this time, the medicine spraying nozzles 5 can perform the spraying operation. Through the combined use of the driving mechanism and the rotating mechanism, a plurality of shielding plates 8 can be driven to rotate simultaneously, canceling the shielding of the output end of the medicine spraying nozzle 5 by the shielding plates 8;

[0031] After the spraying operation is completed, reverse-rotate the motor 11. The motor 11 drives the rotating rod 10, the first bevel gear 12, the second bevel gear 13, the driving pulley 14, the belt 15, the driven pulley 16, and the fixed rod 17 to rotate. At this time, the driven pulley 16 and the fixed rod 17 rotate in the reverse direction, which can drive the baffle 8 to rotate back to block the output end of the spraying nozzle 5. At this time, the dust-proof groove 18 at the top of the baffle 8 closely adheres to the output end of the spraying nozzle 5, which can protect and block it, preventing dust and impurities from entering through the opening of the spraying nozzle 5. After the baffle 8 rotates to the position where it contacts the opening of the spraying nozzle 5, at this time, the output end of the spraying nozzle 5 is located in the dust-proof groove 18 at the top of the baffle 8. As the spraying nozzle 5 is arranged with its opening facing downwards, the liquid medicine remaining in the connecting pipe 4 will drip down and land on the surface of the liquid-absorbing pad 19, and the liquid-absorbing pad 19 can absorb the liquid medicine;

[0032] When the liquid-absorbing pad 19 absorbs a large amount of liquid medicine or when spraying different pesticides, at this time, different liquid medicines drip onto the liquid-absorbing pad 19, and the mixing of different liquid medicines will infect the output end of the spraying nozzle 5, thereby affecting the spraying effect of the pesticide. Therefore, when spraying different pesticides, the liquid-absorbing pad 19 can be replaced. That is, pull out the pin at the top of the threaded rod 22 so that the bottom end of the pin leaves the pin hole at the top of the baffle 8. Subsequently, rotate the threaded rod 22. Under the action of the threaded hole, the threaded rod 22 moves upwards. The threaded rod 22 drives the annular backing plate 23 to move upwards and leave the surface of the connecting membrane 21. At this time, the connecting membrane 21 and the liquid-absorbing pad 19 can be pulled out through the installation groove 20 on the side of the baffle 8. Immediately afterwards, insert the new connecting membrane 21 and the liquid-absorbing pad 19 into the installation groove 20 through the installation groove 20 on the side of the baffle 8, so that the connecting membrane 21 is located in the installation groove 20, and the top of the liquid-absorbing pad 19 penetrates into the dust-proof groove 18. Subsequently, rotate the threaded rod 22 to drive the annular backing plate 23 to move downwards to squeeze and fix the connecting membrane 21. Finally, insert the pin into the pin hole again to complete the fixation of the threaded rod 22.

[0033] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
