[0038] In a further embodiment, referring to Figure 3-Figure 4 A plurality of cover plates 11 are installed above the drone body 1, a slot 111 is provided on the cover plate 11, a slot 2 14 is provided below the slot 111 on the drone body 1, a connecting block 31 is fixedly connected to one end of the flight rod 3, and the connecting block 31 is inserted into the slot 1 111 and the slot 2 14.

[0039] In this embodiment, the flight rod 3 is inserted into the slot 1 111 and the slot 2 14 through the connecting block 31 for clamping, thereby being installed and connected with the drone body 1 .

[0040] In a further embodiment, referring to Figure 3-Figure 4 A through hole is provided in the middle of the drone body 1, and the storage barrel 2 vertically penetrates the drone body 1 through the through hole. A plurality of card blocks 12 are slidably connected to the drone body 1, and the card blocks 12 correspond to the flight rods 3 one by one. The corresponding card blocks 12 and the flight rods 3 are on the same straight line, and one end of the card block 12 can be inserted into the connecting block 31, and the other end of the card block 12 is an inclined surface, and one end of the inclined surface of the card block 12 is located inside the through hole.

[0041] In this embodiment, the diameter of the upper end of the storage barrel 2 is larger than the diameter of the lower end, and the block 12 and the movable rod 13 are limited by the cover plate 11. When the storage barrel 2 is inserted into the through hole, the multiple blocks 12 are squeezed into the drone body 1 by the storage barrel 2, and one end of the block 12 is inserted into the connecting block 31, so that the connecting block 13 cannot be separated from the drone body 1 upward.

[0043] In this embodiment, the movable rod 13 is elastically connected to the drone body 1 through a spring. When the storage barrel 2 is separated from the drone body 1, the movable rod 13 can reset the block 12, so that the connecting block 13 can be separated upward from the drone body 1.

[0044] In a further embodiment, referring to Figure 5-Figure 7 A plurality of mounting blocks 15 are fixedly connected below the drone body 1, the battery rack 5 includes a placement rack 51, the upper end of the placement rack 51 is slidably connected to the mounting block 15, a locking rod 52 is slidably connected to the placement rack 51, a limit rod 16 is slidably connected up and down below the card block 12 inside the drone body 1, the lower end of the limit rod 16 is inserted into the mounting block 15, the upper end of the limit rod 16 is provided with an inclined surface, the lower end of the card block 12 is provided with a second slot 122, and the inclined surface of the second slot 122 is in contact with the inclined surface of the upper end of the limit rod 16.

[0045] In this embodiment, when the block 12 moves into the drone body 1, the block 12 passes over the limit rod 16, and the inclined surface of the upper end of the limit rod 16 is pressed by the inclined surface of the second slot 122, so that the limit rod 16 can be pressed and moved downward, and the lower end of the limit rod 16 can extend to the front side of the upper end of the placement rack 51, so as to limit the placement rack 51 from being separated from the mounting block 15. A spring is provided between the limit rod 16 and the drone body 1 to ensure that the limit rod 16 is automatically reset, so that the placement rack 51 can be separated from the mounting block 15.

[0046] In a further embodiment, referring to Figure 2 The storage barrel 2 comprises a barrel 21, a movable cover 22 is installed on the top of the barrel 21, a horizontal through slot is provided below the barrel 21, a fan 23 is installed at one end of the through slot, and a discharge port 24 is installed at the other side of the through slot.

[0047] In this embodiment, the fan 23 is started to blow wind from one end of the slot to the other end of the slot, and the seeds or fertilizers inside the barrel 21 fall into the slot under the action of gravity, so that when the fan 23 is started, they can be blown out from the outlet 24 at the other end of the slot.

[0048] In a further embodiment, referring to Figure 8-Figure 11 The discharge port 24 includes a discharge fixed end 241, one end of the discharge fixed end 241 is rotatably connected to a discharge rotating end 242, one end of the discharge fixed end 241 is installed with a driving device 244, the driving device 244 is used to drive the discharge rotating end 242 to rotate, one end of the discharge rotating end 242 is symmetrically rotatably connected to a plurality of movable baffles 2421, the lower end of the movable baffle 2421 passes through the discharge rotating end 242 and is fixedly connected to a connecting plate 2422, the outer side of the discharge fixed end 241 is fixedly connected to an annular plate 243, the annular plate 243 passes through the discharge rotating end 242, a discharge opening 2431 is opened horizontally and downwardly on one side of the annular plate 243, one side of the lower end of the annular plate 243 is fixedly connected to a fixed plate 2432, and the fixed plate 2432 is located on the rotation path of the connecting plate 2422.

[0049] In this embodiment, the seeds or fertilizers in the through groove enter the fixed discharge end 241 through wind force, and the driving device 244 drives the discharging rotating end 242 to rotate. When the discharging rotating end 242 rotates and tilts upward, the upper side of the annular plate 243 is located inside the discharging rotating end 242, so that the seeds or fertilizers cannot be spilled from the discharging rotating end 242, so that the drone can fly to the sowing area.

[0050] When the discharging rotating end 242 is horizontal, the horizontal discharging opening 2431 is located inside the discharging rotating end 242, so that seeds or fertilizers can be sprinkled out from the discharging rotating end 242 and sprinkled through the rotating end 242, so as to be gathered, sown, and fertilized when there is wind.

[0051] When the discharging rotating end 242 is horizontal, the discharging opening 2431 on the lower side is located inside the discharging rotating end 242, and at the same time, the connecting plate 2422 on the lower side is close to the fixed plate 2432. After being limited by the fixed plate 2432, the connecting plate 2422 is forced to rotate (to ensure that the connecting plate 2422 can rotate in a fixed direction, the connecting plate 2422 should be tilted in a set direction under normal circumstances). The connecting plate 2422 thereby drives the connecting plate 2422 inside the discharging rotating end 242 to rotate and open to both sides, so that the spilled seeds or fertilizers are in a diffused form.

[0052] In a further embodiment, referring to Fig. 9 The discharging fixed end 241 and the discharging rotating end 242 are internally connected to each other.

[0053] In this embodiment, it is ensured that the waste or seeds flowing out of the fixed discharge end 241 can be sprinkled out through the rotating end 242 .

[0054] In a further embodiment, a spiral spring is provided between the connecting plate 2422 and the discharging rotating end 242 .

[0055] In this embodiment, it is ensured that the connecting plate 2422 can be reset after the connecting plate 2422 is rotated and separated from the fixing plate 2432 .

[0056] In a further embodiment, referring to Figure 1 Support legs 4 are installed on both sides of the storage barrel 2 below the drone body 1, and the lower ends of the support legs 4 are lower than the lower end of the storage barrel 2.

[0057] In this embodiment, the drone body 1 is supported by the supporting legs 4 .

[0058] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
