[0018] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0019] Example 1: An adjustable drone spraying device, see Figures 1 to 3, including an unmanned aerial vehicle body 1, a spray box 2 is installed at the bottom of the unmanned aerial vehicle body 1, and both ends of the spray box 2 are connected with a spray pipe 21, and the bottom outsides of the two spray pipes 21 are connected with a plurality of spray nozzles 22, one end of one of the spray pipes 21 is installed with a servo motor, and the driving end of the servo motor is installed with a drive shaft 36, the inner cavity of the spray pipe 21 is provided with a plurality of annular grooves 31, and the plurality of annular grooves 31 are respectively connected with the plurality of spray nozzles 22, and arc-shaped adjustment blocks 32 are slidably connected on both sides of the inner cavity of the plurality of annular grooves 31, a T-shaped slot 34 is provided at the top of the inner cavity of the spray pipe 21, and the T-shaped slot 34 is connected with the annular slot 31, and the two arc-shaped adjustment blocks 32 are connected with a traction rope 35, and the two traction ropes 35 are connected to the drive shaft 36 through the T-shaped slot 34, and a spring 33 is provided on the outer side of the traction rope 35 in the annular groove 31, and the two ends of the spring 33 are respectively connected with the arc-shaped adjustment blocks The node block 32 is connected to one end of the inner cavity of the annular groove 31, and the spring 33 is always in a compressed state, and the elastic force of the spring 33 is greater than the friction force of the arc-shaped adjustment block 32 in the annular groove 31. When working, the nutrient solution in the spray box 2 is transported to the spray pipe 21 through the pump body (not shown) in the spray box 2, and sprayed through the spray nozzle 22 for spraying the nutrient solution. Then, by starting the drive motor 3 to drive the drive shaft 36 to rotate, the drive shaft 36 can reel in the traction rope 35, so that the traction rope 35 can pull the arc-shaped adjustment block 32 to move and increase the number of connections between the spray nozzle 22 and the spray pipe 21, and at the same time compress the spring 33, and then start the drive motor 3 to drive the drive shaft 36 to rotate to unwind the traction rope 35, so that the elastic force of the compressed spring 33 is raised to the arc-shaped limit block 41 to reset, thereby reducing the number of connections between the spray nozzle 22 and the spray pipe 21, thereby adjusting the range of nutrient solution spraying, thereby improving the spraying efficiency of the nutrient solution.

[0020] For details, see Figure 2 and Figure 3 , limiting grooves 4 are provided on both sides of the inner cavity of the annular groove 31, and both ends of the arc-shaped adjustment block 32 are fixedly connected to the limiting blocks 41, and the two limiting blocks 41 are respectively slidably connected in the two limiting grooves 4. The limiting blocks 41 are guided to move in the limiting grooves 4, thereby improving the stability of the arc-shaped limiting block 41 moving in the annular groove 31.

[0021] For further information, see Figure 3 A sealing gasket 5 is installed at one end of the protrusion of the arc-shaped adjustment block 32, and the sealing gasket 5 is elastic. The sealing gasket 5 increases the sealing performance of the connection between the arc-shaped adjustment block 32, the annular groove 31 and the spray nozzle 22, thereby preventing the unused spray nozzle 22 from leaking and affecting the spraying effect.

[0022] It is worth noting that see Figure 1The spray box 2 is a transparent acrylic box, which is convenient for passing the capacity of the nutrient solution in the spray box 2 through the outside.

[0023] It is worth mentioning that see Figure 2 The spring 33 is a stainless steel spring, and the traction rope 35 is a stainless steel wire rope, which is used to increase the corrosion resistance of the spring 33 and the traction rope 35 and further extend the service life of the spring 33 and the traction rope 35.
