[0013] By adopting the above technical solution, the medicine storage tank and the four-way pipe are both bolted to the helicopter mechanism, which facilitates disassembly and maintenance. The adjustment box is also bolted to the helicopter tail, which is easy to disassemble.
[0014] Optionally, a stirring motor is fixedly installed on the other side of the medicine storage tank, and a stirring rod is fixedly installed on the output shaft of the stirring motor.
[0015] By adopting the above technical solution, turning on the stirring motor to drive the stirring rod to rotate can stir the medicine liquid and prevent the medicine liquid from settling.
[0016] Optionally, the number of the first nozzles is seven, and the number of the second nozzles is eight.
[0017] By adopting the above technical solution, each group of four second nozzles and one second diverter pipe forms a spraying assembly on one side, and the two sets of spraying assemblies can easily expand the spraying range to both sides.
[0018] Optionally, the front of the medicine storage box is connected to a liquid filling pipe, and the top of the liquid filling pipe is provided with a screw cap.
[0019] By adopting the above technical solution, the medicine can be added to the medicine storage tank through the liquid addition tube after opening the screw cap.
[0020] Optionally, a guide slider is fixedly installed on the other side of the adjusting screw block, and a guide groove is provided in the inner cavity of the adjusting box.
[0021] By adopting the above technical solution, the guide slider and the guide groove are used together to guide the adjusting screw block, so that the adjusting screw block can move stably.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. This utility model retains the normal functions of a helicopter by setting up a helicopter mechanism. By setting up an adjustable spraying mechanism, the first nozzle can be used for spraying by turning on the water pump, which facilitates spraying.

Opening the electronic valve allows the liquid to enter the second diverter pipes along the liquid guide hose and be sprayed out through the second nozzle, thereby expanding the spraying range. Controlling the stepper motor to rotate in reverse can retract the second diverter pipes to reduce the area occupied. The pipes can be retracted upon landing to avoid damage, and the spraying range can be adjusted according to actual needs.
[0024] 2. This utility model ensures the normal function of the helicopter mechanism by setting up a propeller and a helicopter tail fin. The landing gear facilitates take-off and landing and ensures the stability of the helicopter body. The medicine storage tank and the four-way pipe are bolted to the helicopter mechanism for easy disassembly and maintenance. The adjustment box is also bolted to the helicopter tail fin for easy disassembly. Turning on the stirring motor drives the stirring rod to rotate, which can stir the medicine liquid and prevent the medicine liquid from settling. Every four second nozzles and one second diverter pipe form a spraying assembly on one side. The two sets of spraying assemblies can easily expand the spraying range to both sides. Opening the cap allows medicine liquid to be added to the medicine storage tank through the liquid filling pipe. The guide slider and guide groove work together to guide the adjusting screw block, making the adjusting screw block move stably. Attached Figure Description

The landing gear 104 is a high-strength metal frame.
[0035] In this embodiment: by setting up the helicopter mechanism 1, the propeller 102 and the helicopter tail 103, the normal function of the helicopter mechanism 1 is ensured, the landing gear 104 facilitates take-off and landing, and ensures the stability of the helicopter body 101.
[0036] Example 2:
[0037] Reference Figure 1-5An adjustable spraying mechanism 2 is installed at the bottom of the helicopter body 101. The adjustable spraying mechanism 2 includes a medicine storage tank 201, a four-way pipe 205, and an adjustment box 207. A water pump 203 is fixedly installed on one side of the medicine storage tank 201. The input end of the water pump 203 is connected to the medicine storage tank 201, and the output end of the water pump 203 is connected to a liquid outlet pipe 204, which is connected to the four-way pipe 205. A liquid guiding metal pipe 206 is connected to the bottom of the four-way pipe 205. One end of the liquid guiding metal pipe 206 is connected to a first diverter pipe 208, which is fixedly connected to the adjustment box 207. A first nozzle 209 is connected to the bottom of the first diverter pipe 208. A stepper motor 210 is fixedly installed on the other side of the inner cavity of the adjustment box 207. A bidirectional threaded rod 211 is fixedly installed on the output shaft of the stepper motor 210. Adjusting screw blocks 212 are threadedly connected to both sides of the surface of the bidirectional threaded rod 211. A second diversion pipe 213 is fixedly installed on one side of the adjusting screw block 212. The bottom of the second diversion pipe 213 is connected to a second nozzle 214. A liquid guiding hose 215 is connected to one side of the second nozzle 214. The liquid guiding hose 215 is connected to a four-way pipe 205. An electronic valve 216 is installed in the inner cavity of the liquid guiding hose 215. The medicine storage tank 201 and the four-way pipe 205 are both fixedly connected to the helicopter body 101. The adjusting box 207 is fixedly connected to the helicopter tail fin 103. A stirring motor 202 is fixedly installed on the other side of the medicine storage tank 201. A stirring rod is fixedly installed on the output shaft of the stirring motor 202. There are seven first nozzles 209 and eight second nozzles 214. A liquid filling pipe 217 is connected to the front of the medicine storage tank 201. A cap is provided on the top of the liquid filling pipe 217. A guide slider is fixedly installed on the other side of the adjusting screw block 212. A guide groove is opened in the inner cavity of the adjusting box 207.
[0038] In this embodiment: an adjustable spraying mechanism 2 is provided. By turning on the water pump 203, the first nozzle 209 can be used for spraying, thus facilitating spraying. Controlling the stepper motor 210 to rotate forward can drive the two second diversion pipes 213 to move away from each other. Opening the electronic valve 216 allows the liquid to enter the second diversion pipes 213 along the liquid guiding hose 215 and be sprayed out through the second nozzle 214, thereby expanding the spraying range. Controlling the stepper motor 210 to rotate in reverse can retract the second diversion pipes 213, reducing the occupied area. The spraying range can be adjusted according to actual needs. The storage tank 201 and the four-way pipe 205 are also included. All components are bolted to the helicopter mechanism 1 for easy disassembly and maintenance.

Turning on the stirring motor 202 drives the stirring rod to rotate, which can stir the liquid and prevent the liquid from settling. Every four second nozzles 214 and one second diverter pipe 213 form a spraying assembly on one side. The two sets of spraying assemblies can easily expand the spraying range to both sides. Opening the cap allows liquid to be added to the storage tank 201 through the liquid filling pipe 217. The guide slider and guide groove work together to guide the adjusting screw block 212, making the adjusting screw block 212 stable when it moves.
[0039] The implementation principle of this utility model is as follows: When in use, the water pump 203 is turned on to extract the liquid medicine from the medicine storage tank 201. The liquid medicine enters the four-way pipe 205 along the outlet pipe 204, and then enters the first diversion pipe 208 along the liquid guiding metal pipe 206 and is sprayed out through the first nozzle 209 for spraying. The stepper motor 210 is controlled to rotate forward to drive the bidirectional threaded rod 211 to rotate. The bidirectional threaded rod 211 drives the two adjusting screw blocks 212 to move away from each other, thereby driving the two second diversion pipes 213 to extend. The electronic valve 216 is opened, and the liquid medicine is sprayed out through the liquid guiding hose 215 through the second diversion pipes 213 and the second nozzle 214. Thus, the first nozzle 209 and the second nozzle 214 can spray medicine at the same time, increasing the spraying range. When it is necessary to land, the stepper motor 210 is controlled to reverse to retract the two second diversion pipes 213 to avoid damage from hitting foreign objects during landing.
[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
