[0024] Please refer to Figures 1-4The walnut tree crown top sprayer based on the drone includes a drone body 1, a spraying assembly 2 is installed just below the drone body 1, and the spraying assembly 2 includes a liquid storage tank 21, a column 211 is welded and fixed at the center of the top of the liquid storage tank 21, and a plurality of slots 213 are regularly opened along the circumference of the upper end of the side wall of the column 211. A fixing column 23 is hinged in the slot 213, and a nut 22 for fixing is threadedly connected to the upper end of the column 211. The bottom end of the liquid storage tank 21 is rotatably connected to a T-shaped catheter 28 through an infusion tube 27, and a plurality of spray heads 29 are provided at the bottom end of the horizontal section of the T-shaped catheter 28. The bottom surface of the liquid storage tank 21 is rotatably connected to a rotating ring block 25, and two fixing rods 251 are symmetrically provided at the bottom end of the rotating ring block 25. The bottom end of the fixing rod 251 is fixed with the two ends of the horizontal section of the T-shaped catheter 28.
[0025] In this embodiment, a groove 11 is provided at the center of the top surface of the drone body 1, and a through hole 12 that is adapted to the size of the column 211 is provided at the center of the groove 11. The bottom surface of the groove 11 is divergently provided with a plurality of fixing grooves 13 that are adapted to the size of the fixing column 23, are equal in number and have corresponding positions; the through hole 12 is used for the column 211 to pass through, and the design of the fixing groove 13 allows the fixing column 23 to be in the groove when it is rotated to the horizontal direction, and then clamped and fixed by the nut 22.
[0026] Furthermore, the outer wall of the upper end of the column 211 is provided with an external thread 212 that is compatible with the nut 22, and the length of the smooth section of the column 211 is equal to the distance from the bottom surface of the drone body 1 to the bottom surface of the groove 11; the design of the external thread 212 enables the column 211 to be threadedly connected with the nut 22, so that the nut 22 can be clamped and fixed after the fixing column 23 is immersed in the fixing groove 13.
[0027] Secondly, a fixed ring block 215 is welded and fixed to the bottom surface of the liquid storage tank 21 , and a ring groove 216 that matches the size of the rotating ring block 25 is opened in the fixed ring block 215 ; the design of the ring groove 216 facilitates the rotation of the rotating ring block 25 in the fixed ring block 215 .
[0028] Furthermore, an outer gear ring 253 is integrally formed at the bottom end of the outer side wall of the rotating ring block 25, and a mounting bracket 214 is welded and fixed to the outer side wall of the liquid storage tank 21. A motor 24 is mounted on the mounting bracket 214, and the output shaft of the motor 24 is coaxially connected to a gear 26, which is meshed with the outer gear ring 253; the motor 24 provides power for the rotation of the gear 26, and the rotation of the gear 26 drives the rotating ring block 25 to rotate through the meshing outer gear ring 253.
[0029] Secondly, the top end of the infusion tube 27 is connected to the liquid outlet 217 provided at the bottom end of the liquid storage tank 21. An electromagnetic switch 271 is installed on the infusion tube 27. The bottom end of the infusion tube 27 is connected to the liquid inlet of the T-shaped catheter 28 through a rotating block 272 with good sealing performance; the design of the electromagnetic switch 271 can control the infusion tube 27 to transmit the liquid to be sprayed, and the rotating block 272 makes it difficult for the liquid to flow out when the T-shaped catheter 28 rotates.
[0030] Furthermore, a fixing ring 252 is welded and fixed to the bottom end of the fixing rod 251, and the inner diameter of the fixing ring 252 is equal to the outer diameter of the horizontal section of the T-shaped tube 28; the fixing ring 252 is sleeved and fixed to the T-shaped tube 28, so that when the rotating ring block 25 rotates, it drives the T-shaped tube 28 to rotate.
[0031] Working principle: When using the drone-based walnut tree crown sprayer of the utility model, the user first injects pesticides or nutrient solution into the liquid storage tank 21, then passes the column 211 through the through hole 12, rotates the fixing column 23 to make it fall into the fixing groove 13, rotates the nut 22 to clamp and fix it, and then starts the drone body 1 to drive the spray component 2 to fly above the walnut tree, turns on the electromagnetic switch 271, so that the pesticide or nutrient solution is sprayed from the spray head 29, and finally starts the motor 24 to drive the gear 26 to rotate, and drives the rotating ring block 25 to rotate through the meshing outer gear ring 253. The rotating ring block 25 rotates and drives the T-shaped guide tube 28 to rotate through the fixing rod 251, so that multiple spray heads 29 rotate accordingly, and the walnut tree crown is evenly sprayed.
[0032] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model.
