[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0023] refer to Figure 1-3A multifunctional drone medicine box includes a box body 11, a connecting structure, and a solid-liquid switching mechanism. The box body 11 is fixedly connected to the connecting structure, which is used to connect to the drone. The box body 11 is connected to the drone through the connecting structure, thereby realizing the connection between the box body 11 and the drone. The box body 11 is provided with a medicine inlet 15 for pouring pesticides into the box body 11.

[0024] A solid-liquid switching mechanism is installed on a housing 11. A feeding cylinder 21 is fixedly connected to the bottom of the housing 11. A feeding trough 22 communicating with the housing 11 is provided on the upper side of the feeding cylinder 21. A worm gear 23 is rotatably connected to the feeding cylinder 21. The worm gear 23 extends along the length of the feeding trough 22. The solid-liquid switching mechanism includes a fixed sleeve 31, a rotating sleeve 32, and a rotating plate 33. The fixed sleeve 31 is fixedly connected to the housing 11 and communicates with the feeding trough 22. The rotating plate 33 is rotatably connected to the fixed sleeve 31, and the rotating sleeve 32 is fixedly connected to the rotating plate 33. The worm gear 23 extends into the rotating sleeve 32. The rotating sleeve 32 is provided with a through groove 34. The lower side of the fixed sleeve 31 is provided with a discharge port 35 communicating with the through groove 34. The surface of the worm gear 23 is provided with helical blades. When the worm gear 23 rotates, the helical blades can push the powdered or granular solid pesticide to move along the axial direction of the worm gear 23, realizing the function of the worm gear 23 pushing the pesticide to move towards the through groove 34 when rotating. A support plate 24 is fixedly connected to the housing 11. A drive component 25 is fixedly mounted on the support plate 24. The output shaft of the drive component 25 is fixedly connected to the worm gear 23. The drive component 25 is a geared motor. The drive component 25 drives the worm gear 23 to rotate, thus realizing the function of driving the worm gear 23 to rotate. A support sleeve 26 is provided between the support plate 24 and the feeding cylinder 21. The two ends of the support sleeve 26 are fixedly connected to the support plate 24 and the feeding cylinder 21, respectively. The worm gear 23 is rotatably connected to the support sleeve 26. The feeding cylinder 21 and the worm gear 23 are inclined, and the discharge port 35 is located at the lower end of the worm gear 23.

[0025] The rotating plate 33 has a through hole 36, and the fixed sleeve 31 has a liquid outlet hole 37 communicating with the through hole 36. The through hole 36 is located at the end of the rotating plate 33 away from the through groove 34. When the through groove 34 is connected to the discharge port 35, the through hole 36 and the liquid outlet hole 37 are offset; when the through hole 36 and the liquid outlet hole 37 are connected, the through groove 34 and the discharge port 35 are offset. The fixed sleeve 31 is fixedly connected to a spray pipe 38 communicating with the liquid outlet hole 37, and the spray pipe 38 is equipped with a solenoid valve 39. The rotating plate 33 is fixedly connected to a rotating shaft 41, which extends outside the fixed sleeve 31. The rotating shaft 41 is fixedly connected to a rotating wheel 42 located outside the fixed sleeve 31. Rotating the rotating wheel 42 outside the fixed sleeve 31 drives the rotating plate 33 and the rotating sleeve 32 to rotate through the rotating shaft 41, which facilitates the rotation of the rotating plate 33 and the rotating sleeve 32. A connecting block 46 is fixedly connected to the fixed sleeve 31. A locking pin 43 passes through the connecting block 46, and the rotating shaft 41 has a pin hole 44 for the locking pin 43 to be inserted. Inserting the locking pin 43 into the pin hole 44 locks the rotating shaft 41, the rotating plate 33, and the rotating sleeve 32. A metal threaded sleeve 45 is fixedly connected to the connecting block 46, and the locking pin 43 is threadedly connected to the metal threaded sleeve 45.

[0026] The connection structure includes a top connecting plate 12, a side connecting plate 13, and a connecting sleeve 14. The top connecting plate 12 and the side connecting plate 13 are fixedly connected. The top connecting plate 12 is fixedly connected to the upper wall of the housing 11. The side connecting plate 13 is fixedly connected to the side wall of the housing 11. The connecting sleeve 14 is fixedly connected to the upper side of the top connecting plate 12.

[0027] When liquid pesticides need to be sprayed, the drive plate 33 and the rotating sleeve 32 will rotate, causing the through groove 34 to be misaligned with the discharge port 35 and the through hole 36 to connect with the liquid outlet 37. Figure 2 As shown. Liquid pesticide is added to the container 11. The pesticide in the container 11 can flow into the feeding trough 22, and then flow along the spiral direction of the worm gear 23 blades into the through hole 36, the liquid outlet 37, and the spray pipe 38. After the drone moves the container 11 to the position where the pesticide needs to be applied, it opens the solenoid valve 39, allowing the liquid pesticide to be sprayed onto the plants through the spray pipe 38, thus achieving the spraying of liquid pesticide.

[0028] When solid pesticides need to be applied, the rotating plate 33 and rotating sleeve 32 are driven to rotate, causing the through groove 34 to rotate to the position corresponding to the discharge port 35, thereby connecting the through groove 34 and the discharge port 35. Figure 3 As shown. Powdered or granular solid pesticides are placed into the housing 11. The solid pesticides in the housing 11 roll into the feeding trough 22 and come into contact with the worm gear 23. After the drone moves the housing 11 to the position where the pesticides need to be applied, it drives the worm gear 23 to rotate, causing the worm gear 23 to push the solid pesticides towards the through trough 34. After the solid pesticides reach the through trough 34, they are discharged from the housing 11 and the feeding cylinder 21 through the through trough 34 and the discharge port 35, thereby achieving the application of solid pesticides.

[0029] This embodiment has the following advantages: The worm gear 23 drives the solid pesticide to move towards the channel 34 and the outlet 35, thereby actively providing thrust to the solid pesticide. This effectively prevents the solid pesticide from clogging, making the application of the solid pesticide smoother and achieving the advantage of not being prone to clogging.

[0030] When the worm gear 23 rotates at a faster speed, it drives the solid pesticide to move at a faster speed; when the worm gear 23 rotates at a slower speed, it drives the solid pesticide to move at a slower speed. Therefore, by controlling the rotation speed of the worm gear 23, the application speed of the solid pesticide can be adjusted.

[0031] By rotating the rotating plate 33 and the rotating sleeve 32, the delivery mode of fixed pesticides and liquid pesticides can be switched, thereby realizing the functions of solid pesticide sowing and liquid pesticide spraying respectively, making one box a dual-purpose device.

[0032] When liquid pesticides are stored in the housing 11, the worm gear 23 is driven to rotate, which can stir the liquid pesticides in the feeding trough 22 and the housing 11, effectively preventing the pesticides from settling, making the concentration of the liquid pesticides uniform, and ensuring the spraying effect of the liquid pesticides.

[0033] By tightening the locking pin 43, the locking pin 43 and the metal threaded sleeve 45 achieve self-locking through friction, preventing the locking pin 43 from accidentally slipping out of the pin hole 44. Both the metal threaded sleeve 45 and the locking pin 43 are made of metal, which has good wear resistance, improving service life and structural reliability.

[0034] The support sleeve 26 provides support to the side wall of the worm gear 23, enabling the worm gear 23 to rotate stably. The feed cylinder 21 provides support to the support plate 24 through the support sleeve 26, which improves the structural stability of the support plate 24, prevents the support plate 24 from breaking, and ensures the reliability of the support plate 24 and the drive component 25.

[0035] The top connecting plate 12 and the side connecting plate 13 are fixed to the top and side of the housing 11 respectively, which improves the connection strength between the connecting structure and the housing 11. The top connecting plate 12 and the side support plate 24 themselves can support the housing 11 and prevent the housing 11 from deforming. The connecting sleeve 14 has internal threads, which facilitates the connection of the connecting structure to the drone through studs.

[0036] By tilting the feeding cylinder 21 and the worm gear 23, and setting the discharge port 35 at the lower end of the worm gear 23, the solid pesticide can move more easily to the discharge port 35 through gravity, further preventing the solid pesticide from clogging.

[0037] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
