[0029] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0030] A pesticide spraying mechanism comprises a drone body 1, the top of which is fixedly connected to a U-shaped mounting seat 11 by bolts, and a limiting groove 12 is provided at the bottom of the inner wall of the U-shaped mounting seat 11 for cooperating with a limiting plate 22 to limit the position of a liquid storage tank 2.

[0031] As a preferred embodiment of the present invention, the right side surface of the U-shaped mounting seat 11 is fixedly connected to a U-shaped mounting seat 13 by bolts, and the inner wall of the U-shaped mounting seat 13 is slidably connected to a slider 14 for limiting the moving direction of the plug plate 15 .

[0032] Specifically, the left surface of the slider 14 is fixedly connected with an insert plate 15 by bolts. The left end of the insert plate 15 passes through the left end of the U-shaped mounting seat 13 and the right end of the U-shaped mounting seat 11 in sequence and is plugged into the inner wall of the slot 21 to limit the position of the liquid storage tank 2.

[0033] Specifically, a pull rod 16 is fixedly connected to the right surface of the slider 14 by bolts to drive the slider 14 to move. The right end of the pull rod 16 passes through the right end of the U-shaped mounting seat 13 and is welded and fixed with a pull ring 17 to drive the pull rod 16 to move.

[0034] Specifically, a spring 18 is provided on the circumferential outer wall of the pull rod 16 to limit the position of the slider 14 .

[0035] Furthermore, a liquid storage tank 2 is provided at the bottom of the inner wall of the U-shaped mounting seat 13, and a top cover is provided on the top of the liquid storage tank 2. The left and right side surfaces of the liquid storage tank 2 are respectively in contact with the left and right side surfaces of the inner wall of the U-shaped mounting seat 13 for storing pesticides. A slot 21 is provided at the right end of the liquid storage tank 2.

[0036] Specifically, the bottom of the liquid storage tank 2 is fixedly connected to a limit plate 22 by bolts, and the limit plate 22 is plugged into and matched with the inner wall of the limit groove 12 to limit the position of the liquid storage tank 2.

[0037] Specifically, the left and right surfaces of the liquid storage tank 2 are symmetrically fixed with feeding pumps 23 by bolts, and the feed ports of the two feeding pumps 23 are respectively connected to liquid inlet pipes 24. The two liquid inlet pipes 24 respectively penetrate the left and right ends of the liquid storage tank 2 and pass into the inner cavity of the liquid storage tank 2. A liquid inlet port 25 is opened on the circumferential outer wall of the liquid inlet pipe 24, which is used to introduce the pesticide in the liquid storage tank 2 into the liquid inlet pipe 24.

[0038] Specifically, the discharge port of the feed pump 23 is connected to a main liquid outlet pipe 26 for introducing pesticides into an auxiliary liquid outlet pipe 27 , and one end of the main liquid outlet pipe 26 is symmetrically connected to an auxiliary liquid outlet pipe 27 near the front and rear sides for introducing pesticides into a spray head 28 .

[0039] Specifically, a plurality of spray heads 28 are fixedly connected to the auxiliary liquid outlet pipe 27 by bolts for spraying pesticides. The spray heads 28 are evenly arranged at equal intervals, and the spray heads 28, the auxiliary liquid outlet pipe 27 and the main liquid outlet pipe 26 are connected in sequence.

[0040] Furthermore, a partition mechanism 3 is provided in the liquid storage tank 2. The partition mechanism 3 includes an adjusting motor 31. The adjusting motor 31 is fixedly connected to the right side surface of the liquid storage tank 2 by bolts to drive the threaded rod 32 to rotate.

[0041] It should be added that the output shaft of the regulating motor 31 is coaxially connected with a threaded rod 32 , the left end of which passes through the right end of the liquid storage tank 2 and fits against the left surface of the inner wall of the liquid storage tank 2 to drive the partition plate 33 to move.

[0042] Specifically, the threaded rod 32 is threadedly connected with a partition plate 33, and the partition plate 33 is slidably connected to the inner wall of the liquid storage tank 2. The pesticide on the right side of the partition plate 33 cannot move to the left side of the partition plate 33, which is used to separate the internal space of the liquid storage tank 2.

[0043] It is worth mentioning that the structure and working principle of the drone body 1 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0044] During specific use, when the pesticide in the liquid storage tank 2 is used up, the user first pulls the pull ring 17 to the right, thereby driving the pull rod 16 to move to the right, thereby driving the slider 14 to move to the right, thereby driving the plug plate 15 to move to the right. In this process, the slider 14 compresses the spring 18;

[0045] When the spring 18 is compressed to the shortest length, the plug plate 15 is no longer plugged into the inner wall of the slot 21, and the liquid storage tank 2 is moved upward until the outer wall of the liquid storage tank 2 is no longer in contact with the inner wall of the U-shaped mounting seat 11, and another liquid storage tank 2 filled with pesticides is placed at the bottom of the inner wall of the U-shaped mounting seat 11 and the limiting plate 22 at the bottom of the liquid storage tank 2 is plugged into the inner wall of the limiting groove 12;

[0046] Release the pull ring 17, and the spring 18 starts to restore its initial length, thereby driving the slider 14 to move leftward, thereby driving the insert plate 15 to move leftward, until the spring 18 restores its initial length, the insert plate 15 is plugged into and matched with the inner wall of the slot 21 opened at the right end of the new liquid storage tank 2, and the replacement of the liquid storage tank 2 is completed;

[0047] When the internal space layout of the liquid storage tank 2 needs to be adjusted, the user first turns on the adjustment motor 31, and the adjustment motor 31 drives the threaded rod 32 to rotate, thereby driving the partition plate 33 to move to the left until the distance between the left side surface of the partition plate 33 and the left side surface of the inner wall of the liquid storage tank 2 reaches the specified distance, and then turns off the adjustment motor 31.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
