[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a drone variable fertilization device, a drone body 1 and a storage box 11 disposed on the top of the drone body 1;

[0027] A stirring assembly 2 is placed inside the storage tank 11. The stirring assembly 2 includes a support column 21 fixedly connected to the top of the storage tank 11. A support rod 22 is provided inside the support column 21. A first connecting rod 23 is rotatably connected to the bottom of the support rod 22. A sleeve 25 is fixedly connected to the inner cavity of the first connecting rod 23. A fixing rod 28 is provided inside the inner cavity of the sleeve 25. A third connecting rod 210 is fixedly connected to the bottom of the fixing rod 28. A discharge pipe 29 is fixedly connected to the bottom of the storage tank 11.

[0028] Drive assembly 3 is placed on top of stirring assembly 2. Drive assembly 3 includes a mounting base 31 fixedly connected to the top of storage tank 11. A gear 32 is provided on the top of mounting base 31. The bottom of gear 32 is fixedly connected to the top of support rod 22. A groove 24 is provided in the inner cavity of support rod 21. One side of support rod 22 extends into the inner cavity of groove 24. The side of support rod 21 is slidably connected to the inner cavity of groove 24. A first limiting groove 26 is provided on the outer surface of sleeve 25. A second connecting rod 27 is provided on the top of fixed rod 28. The second connecting rod 27 is located away from fixed rod 28. The end is fixedly connected to the top of the inner cavity of the sleeve 25. A guide groove 211 is provided on the side of the third connecting rod 210. The third connecting rod 210 is slidably connected to the inner cavity of the discharge pipe 29. A handle is provided on the top of the storage box 11. When using it, first manually lift the handle upward to open the inner cavity of the storage box 11. Pour the prepared fertilizer into the inner cavity of the storage box 11. Then start the motor on the top of the cam 38. The output shaft of the motor rotates forward, which drives the gear 32 to move clockwise through the tooth block 39. This enables the support rod 22 to move along the inner cavity of the support column 21. The clockwise motion effect occurs when the support rod 22 moves to a certain position and then moves downwards, thereby driving the third connecting rod 210 downwards via the first connecting rod 23. When the first connecting rod 23 moves to a certain position, it is coordinated with the sleeve 25 and the fixed rod 28 to cause the first connecting rod 23 to move clockwise. By setting the first limiting groove 26, the movement trajectory of the fixed rod 28 can be limited, preventing the fixed rod 28 from disengaging from the inner cavity of the sleeve 25 during movement. At this time, the support rod 22 continues to move, thereby causing the first connecting rod 210 to move clockwise. The first connecting rod 23 moves upward, thereby driving the stirring rod to stir up and down repeatedly, preventing fertilizer from accumulating in the inner cavity of the storage box 11. At the same time, the third connecting rod 210 moves up and down along the inner cavity of the discharge pipe 29, which can effectively prevent the fertilizer from being unevenly distributed in the inner cavity of the storage box 11 due to sudden changes in flow rate when adjusting the amount of fertilizer to be spread. By setting the guide trough 211, the fertilizer throughput can be effectively improved. By setting the second connecting rod 27, the first connecting rod 23 and the fixed rod 28 can be stably driven.

[0029] Furthermore, such as Figure 3 and Figure 4As shown: A toothed block 39 meshes with the side of the gear 32. A limiting plate 35 is fixedly connected to the end of the toothed block 39 away from the gear 32. A contact block 34 is fixedly connected to the top of the limiting plate 35. A second limiting groove 37 is opened on the top of the limiting plate 35. A cam 38 is provided in the inner cavity of the limiting plate 35. A limiting rod 36 is slidably connected to the inner cavity of the second limiting groove 37. The bottom of the limiting rod 36 is fixedly connected to the top of the mounting base 31. A small motor is provided on the top of the cam 38. When the motor output rotates forward, it can drive the limiting plate 35 to move through the cam 38. When the limiting plate 35 moves to a certain position, the side of the toothed block 39 meshes with the side of the gear 32, thereby causing the gear 32 to move clockwise. At this time, the cam 38 continues to move, thereby causing the toothed block 39 to disengage from the outer surface of the gear 32, thus achieving the effect of causing the gear 32 to rotate intermittently, effectively improving the service life of the gear 32 and reducing energy consumption.

[0030] During the operation of the tooth block 39 and gear 32, due to the inevitable vibrations that occur during the flight of the UAV, the position of the tooth block 39 after disengaging from the gear 32 and re-engaging will shift to a certain extent. For example... Figure 4 As shown: In this design, a lever 33 is provided at the end of gear 32 away from support rod 22. After the side of tooth block 39 meshes with the side of gear 32, tooth block 39 continues to move, thereby driving contact block 34 to move. When contact block 34 moves to a certain position, the side of contact block 34 contacts the bottom of lever 33, thereby causing the end of lever 33 away from contact block 34 to move closer to gear 32. This achieves the effect of positioning gear 32 when tooth block 39 disengages from the inner cavity of gear 32, effectively improving the meshing stability of tooth block 39 and gear 32.

[0031] like Figures 1-4 As shown:

[0032] In use: First, manually move the handle upwards to open the inner cavity of the storage box 11. Pour the prepared fertilizer into the inner cavity of the storage box 11. Then, start the motor on top of the cam 38. The motor's output shaft rotates clockwise, which drives the limiting plate 35 to move via the cam 38. When the limiting plate 35 moves to a certain position, the side of the tooth block 39 meshes with the side of the gear 32, causing the gear 32 to move clockwise. At this time, the cam 38 continues to move, causing the tooth block 39 to disengage from the outer surface of the gear 32, thus achieving the effect of intermittent rotation of the gear 32. When the gear 32 moves clockwise, it drives the support rod 22 to move clockwise along the inner cavity of the groove 24. When the support rod 22 moves to a certain position, it moves downwards. This allows the first connecting rod 23 to drive the third connecting rod 210 downwards. When the first connecting rod 23 reaches a certain position, the sleeve 25 and the fixing rod 28 work together to make the first connecting rod 23 move clockwise. At this time, the support rod 22 continues to move, which in turn causes the first connecting rod 23 to move upwards. This achieves the effect of the first connecting rod 23 driving the stirring rod to stir up and down, preventing fertilizer from accumulating in the inner cavity of the storage box 11. At the same time, the third connecting rod 210 moves up and down along the inner cavity of the discharge pipe 29, which effectively avoids the problem of uneven distribution of fertilizer in the inner cavity of the storage box 11 due to sudden changes in flow rate when adjusting the amount of fertilizer applied. By setting the guide trough 211, the fertilizer throughput can be effectively improved.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
