[0031] The spraying assembly 2 includes a telescopic adjustment unit and an angle adjustment unit. The telescopic adjustment unit is used to adjust the spraying distance, and the angle adjustment unit is used to adjust the spraying angle.

[0032] The telescopic adjustment unit includes a telescopic rod 201, a nozzle 202, an annular toothed groove 203, a first worm gear reducer 205, and a first gear 206;

[0033] There are two telescopic rods 201. The two telescopic rods 201 are distributed in parallel on the inner side of the support frame 101 and extend to both outer ends of the support frame 101. The telescopic rods 201 are slidably connected to the support frame 101.

[0034] The nozzles 202 are respectively fixed to the bottom of the two telescopic rods 201 at opposite ends, and the annular toothed grooves 203 are formed on the outer side of the telescopic rods 201 at the end away from the nozzles 202.

[0035] The first worm gear reducer 205 is fixed to the top middle of the support frame 101. The output end of the first worm gear reducer 205 passes through the inside of the support frame 101 and is fixedly connected to the first gear 206.

[0043] During the spraying process, the distance and angle between the two nozzles 202 can be adjusted, as follows:

[0044] When adjusting the spacing, the first worm gear reducer 205 is started by controlling it to drive the first gear 206 to rotate. The rotating first gear 206 can push the two telescopic rods 201 to move horizontally through the annular tooth grooves 203 on the two telescopic rods 201. The two telescopic rods 201 move in opposite directions, thereby realizing the adjustment of the spacing between the two nozzles 202.

[0045] When adjusting the angle, the second worm gear reducer 207 is started. The second worm gear reducer 207 drives the second gear 207 to rotate. The second gear 207 drives the telescopic rod 201 to rotate under the cooperation of the strip tooth groove 204, thereby realizing the angle adjustment of the nozzle 202.

[0046] Through the cooperation of the above components, the spray nozzle 202 can adapt to the row spacing of different crops, effectively avoiding waste of pesticide solution and incomplete coverage, and further improving the flexibility and applicability of the pesticide solution.
