[0022] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 , Instruction Manual Figure 6 And the instruction manual Figure 8 The turning frame 8 includes a second gear 47 installed on the connecting rod 42, a circular ring platform 48 is provided on the outer side of the cylindrical lifting platform 4, and the circular ring platform 48 is connected to the cylindrical lifting platform 4 of the rotating screw 15 through a plurality of connecting shafts 49. A circular rack 50 is installed on the upper end of the circular ring platform 48, and the circular rack 50 is meshed with the second gear 47. A fixing plate 51 is installed on the upper end of the rotating screw 15, and an arc-shaped pushing plate 52 is installed on the lower end of the fixing plate 51. When the rotating platform 10 is separated from the limiting rod 12, the arc-shaped pushing plate 52 can contact the rotating platform 10. The arc-shaped pushing plate 52 is A square opening 53 is opened on the side, and an arc-shaped telescopic plate 54 is arranged in the square opening 53. The arc-shaped telescopic plate 54 and the inner side of the square opening 53 are connected by a plurality of telescopic springs 55. A spring ejector pin 56 is installed on one side of the lower end of the arc-shaped telescopic plate 54. An L-shaped positioning rod 57 is installed on the upper end of the screw bearing 18. The L-shaped positioning rod 57 can limit the rotating table 10. When the arc-shaped pushing plate 52 pushes the rotating table 10 for one circle, the L-shaped positioning rod 57 can contact the rotating table 10. When the rotating table 10 rotates, the first gear 40 and the gear slot 41 are disconnected; The process of the turning frame 8 turning the spray pipe 6 is as follows: when the cylindrical lifting platform 4 moves upward and the limiting hole 11 moves to the top of the limiting rod 12, the rotating platform 10 first contacts the spring ejector pin 56 and compresses the spring ejector pin 56. When the spring ejector pin 56 rotates to one side of the rotating platform 10, the spring ejector pin 56 can be restored to its original state. Under the rotation of the rotating screw 15, the arc-shaped pushing plate 52 can contact the upper end of the rotating platform 10 and push the rotating platform 10 to one side. The rotating platform 10 can drive the connecting rod 42, the second gear 47, the spray pipe 6, and the medicine box 5 to rotate. The second gear 47 is meshed with the circular rack 50. The second gear 47 can rotate while the second gear 47 rotates around the rotating platform 10, thereby driving the connecting rod 47 and the spray pipe 6 to rotate, thereby causing the spray pipe 6 to turn over. Go to the other side of the tree, and then position the rotating platform 10 through the L-shaped positioning rod 57, and then reverse the rotating screw 15 to move the cylindrical lifting platform 4 downward. When the cylindrical lifting platform 4 moves downward, it can drive the rotating platform 10 to move downward. The one-way bearing 9 can prevent the rotating platform 10 from reversing. When the rotating platform 10 leaves the L-shaped positioning rod 47, the spring ejector pin 56 at the lower end of the arc-shaped telescopic plate 54 contacts the rotating platform 10 to prevent the rotating platform 10 from rotating forward. Since the rotating platform 10 cannot be reversed, the arc-shaped telescopic plate 54 can be retracted into the square opening 53 and the telescopic spring 55 can be compressed. When the limiting hole 11 on the rotating platform 10 moves to the upper end of the limiting rod 12, the spring ejector pin 56 is separated from the rotating platform 10, thereby ensuring the position of the rotating platform 10.

[0023] Refer to the instruction manual Figure 1 And the instruction manual Figure 5 The mobile platform 1 is also provided with a liquid replenishing mechanism, which includes a liquid inlet valve 58 installed on one side of the upper end of the square box 23, a pressure valve 59 installed on one side of the lower end of the square box 23, and an outlet end of the pressure valve 59 is connected to the connecting pipe 7. A solution box 60 is installed on the upper surface of the mobile platform 1, and a liquid adding valve 61 is installed on one side of the lower end of the solution box 60. A liquid adding pipe 62 is installed on the outlet end of the liquid adding valve 61. When the square box 23 moves up and down, the lifting piston 24 can move up and down in the square box 23. When the lifting piston 24 moves downward, the medicine in the square box 23 can break through the pressure valve 59 and spray out. When the lifting piston 24 moves upward, the lifting piston 24 can move to the top of the liquid inlet valve 58. If the amount of medicine in the square box 23 is small, liquid can be added through the liquid adding valve 61 and the liquid adding pipe 62. If the amount of medicine in the square box 23 is large, no liquid needs to be added.

[0024] The liquid adding pipe 62 is rotatably connected to the liquid adding valve 61. Under normal circumstances, the liquid adding pipe 62 is biased to one side to avoid the liquid inlet valve 58. When liquid needs to be added, the liquid adding pipe 62 is rotated to a position corresponding to the liquid inlet valve 58, and the liquid adding valve 58 is opened to add liquid.

[0025] Refer to the instruction manual Figure 1 And the instruction manual Fig. 9 An L-shaped detection tube 63 is installed on one side of the lower end of the square box 23, and the upper end of the L-shaped detection tube 63 is closed. When the lifting piston 24 moves to above the liquid inlet valve 58, the internal space of the square box 23 can be connected with the external space, so that the liquid level in the L-shaped detection tube 63 can be the same as the liquid level in the square box 23. The staff can observe the liquid level of the L-shaped detection tube 63 to judge the liquid level in the square box 23.
