Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] Embodiments of this utility model: such as Figure 1-5 As shown, a drone pesticide spraying device includes a body 1, a pesticide tank 2, and a frame 3. The frame 3 is fixedly installed at the bottom of the body 1, and the pesticide tank 2 is installed on the frame 3. The frame 3 is provided with a support plate 4 for supporting the pesticide tank 2. The support plate 4 is slidably connected to the frame 3. The bottom front end of the support plate 4 is provided with a support leg 5, and the bottom of the support plate 4 is provided with a storage groove 6, into which the support leg 5 can be retracted. The frame 3 is provided with two fixing frames 7, located on both sides of the pesticide tank 2. The side wall of the pesticide tank 2 is provided with a limiting groove 8 corresponding to the support plate 4 and the fixing frame 7. The fixing frame 7 is hinged to the frame 3 and can be rotated into the limiting groove 8. The top of the two fixing frames 7 is provided with a fixing lock 9, and the two fixing frames 7 are connected and fixed by the fixing lock 9.
[0023] It is worth noting that a fixing pin can be set on the side wall of the storage slot 6, and a pin hole can be set on the support leg 5 to fix the support leg 5 and prevent the support leg 5 from coming off during flight.
[0024] It is worth noting that, as shown in the figure, the support plate 4 has a baffle at the rear end. When placing the medicine box 2, pressing the rear end of the medicine box 2 against the baffle indicates that it is in place.
[0025] With the above structure, when taking out or placing the medicine box 2, the support plate 4 is pulled out and the support leg 5 is taken out for support, which facilitates the placement of the medicine box 2 and can prevent the drone from tipping over when placing the medicine box 2. Align the limiting groove 8 at the bottom of the medicine box 2 with the support plate 4, place the medicine box 2 on the support plate 4 and press it against the rear baffle. Then push the support plate 4 back into the frame 3, and the fixing bracket 7 aligns with the limiting groove 8 on the side wall of the medicine box 2. Rotating the two fixing brackets 7 towards the middle can lock them into the limiting groove 8 of the medicine box 2 and they can be connected and fixed by the fixing lock 2, thereby fixing the medicine box 2. The support plate 4, the fixing bracket 7 and the corresponding limiting groove 8 are engaged to prevent the medicine box 2 from shifting.
[0026] like Figure 2 , 4 As shown, the length direction of the storage groove 6 is perpendicular to the moving direction of the support plate 4, and the bottom of the support leg 5 is provided with a moving wheel 10.
[0027] The above structure facilitates the support leg 5 to support the support plate 4, preventing the medicine box 2 from being placed on the support plate 4 after the support plate 4 extends, which could cause the drone to tip over. The moving wheel 10 makes it easy to push the support plate 4 back into the frame 3.
[0028] like Figure 2 , 4 As shown in Figure 6, a stirring paddle 11 is rotatably installed inside the medicine tank 2. The top of the stirring paddle 11 extends to the outside of the medicine tank 2. A liquid dispensing port is provided on the top of the medicine tank 2, and a cover 12 is installed on the liquid dispensing port. The stirring paddle 11 passes through the cover 12 and is rotatably mounted on the cover 12. The top of the stirring paddle 11 is flush with the top surface of the cover 12.
[0029] like Figure 6 As shown, the top of the stirring paddle 4 is provided with a hexagonal slot 19, and a crank 20 is inserted into the hexagonal slot 19.
[0030] With the above structure, when preparing the pesticide solution, the medicine box 2 is taken out, the cover 12 is opened and water and pesticide are added, the cover 12 is closed and the crank handle 20 is inserted into the hexagonal slot 19, so that the stirring paddle 11 can be rotated to stir and mix evenly.
[0031] like Figure 2-5 As shown, the top of the fixing frame 7 is provided with a positioning half ring 13, and the two positioning half rings 13 are respectively locked on both sides of the cover 12. Both ends of the positioning half ring 13 are provided with ear pieces 14, and the fixing lock 9 is set on the ear pieces 14.
[0032] The fixed lock 9 includes a rotating shaft 15 and a semi-circular locking plate 16. The semi-circular locking plate 16 is rotatably connected to a lug 14 via the rotating shaft 15. The opposite lug 14 is provided with a semi-circular locking hole 17, and the semi-circular locking plate 16 passes through the semi-circular locking hole 17.
[0033] With the above structure, the semicircular locking plate 16 can be aligned with the semicircular locking hole 17 by rotation. The semicircular locking plate 16 is passed through the semicircular locking hole 17, and then rotated in the opposite direction to make the semicircular locking plate 16 and the semicircular locking hole 17 misaligned, thus locking the device.
[0034] like Figure 3 As shown, a torsion spring 18 is sleeved on the rotating shaft 15, and the two ends of the torsion spring 18 are fixedly connected to the lug 14 and the rotating shaft 15, respectively.
[0035] It is worth noting that when the torsion spring 18 is in its natural state, the semi-circular locking plate 16 is offset from the semi-circular locking hole 17.
[0036] With the above structure, the semi-circular lock plate 16 can automatically reset after passing through the semi-circular lock hole 17, thereby preventing the fixed lock 9 from unlocking automatically.
[0037] The support plate 4 and the fixing frame 7 are provided with cushioning pads on the surfaces that contact the medicine box 2.
[0038] Through the above structure, the design of the buffer pad can protect the medicine box 2, provide cushioning during the flight of the drone, and increase friction to prevent the medicine box 2 from shifting.
[0039] In practical use of this utility model, when replacing the medicine box 2, after the drone is parked, unlock the fixing lock 9, rotate the fixing frame 7 to both sides to separate it from the medicine box 2, take out the support leg 5, and pull the support plate 4 outward to make the medicine box 2 leave the frame 3 for easy removal; then place the other medicine box 2 with the prepared medicine solution on the support plate 4, so that the medicine box 2 is pressed against the baffle on the support plate 4, push the support plate 4 back into the frame 3, retract the support leg 5 into the storage slot 6, and then rotate the fixing frame 7 to the middle to lock the fixing lock 9 for fixation.
