[0055] An exposure groove is arranged on the adjusting outer support leg 12, and the position of the exposure groove corresponds to the position of the rack 30.

[0056] A first connecting rod 35 is arranged inside the driving housing 15.

A sliding frame 43 is slidably connected to the first connecting rod 35. A second spring 41 is arranged between the sliding frame 43 and the fixing frame 14. The second spring 41 is sleeved outside the first connecting rod 35;

[0057] A sliding sleeve plate 44 is fixedly connected to the sliding frame 43. A second connecting rod 36 is inserted into the sliding sleeve plate 44. A third spring 42 is sleeved on the second connecting rod 36. The upper end of the third spring 42 abuts against the limiting piece at the upper end of the second connecting rod 36, and the lower end of the third spring 42 abuts against the sliding sleeve plate 44;

[0058] The lower end of the second connecting rod 36 is fixedly connected to a stabilizing frame 34. The stabilizing frame 34 is slidably connected to a fixed sliding sleeve 40. The fixed sliding sleeve 40 is fixedly connected to a sliding sleeve fixing rod 39. The sliding sleeve fixing rod 39 is fixedly connected to the adjusting housing inside the driving housing 15;

[0059] Clamping columns 37 are fixedly connected to both lower ends of the stabilizing frame 34.

[0060] A limit fixing sleeve 46 is fixedly connected to the adjusted outer support leg 12. A sliding groove block 50 is fixedly connected between the limit fixing sleeves 46. A sliding clamping rod is slidably inserted into the sliding groove block 50. A clamping strip fixing plate 47 is fixedly connected to the side of the sliding clamping rod facing the rack 30. A clamping strip 48 is fixedly connected to the clamping strip fixing plate 47.

[0062] The wedge block 38 can cooperate with the clamping position column 37.

[0063] The working principle and beneficial effects of the above scheme:

[0064] When adjusting the height of the nozzle 10, press the adjustment handle 16. The end of the adjustment handle 16 located in the drive housing 15 moves upward, driving the linkage cross bar 45 to move upward. By squeezing the third spring 42 through the sliding sleeve plate 44, the stabilizing frame 34 moves upward. The clamping position column 37 fixed on the stabilizing frame 34 clamps the wedge block 38, causing the wedge block 38 to move against the elastic force of the fourth spring 49, driving the clamping strip 48 to move, and making the clamping strip 48 release the restriction on the rack 30;

[0065] When continuing to press the adjustment handle 16, the second spring 41 and the third spring 42 are compressed, and the stabilizing frame 34 is restricted and no longer continues to rise. Continuing to press the adjustment handle 16 will drive the toothed plate 19 to move, driving the first gear 20 meshing with the toothed plate 19 to rotate, and then driving the first ratchet wheel 23 to rotate. The first ratchet wheel 23 drives the first bevel gear 27 to rotate through the second ratchet wheel 24, and then the second bevel gear 28 and the second gear 29 rotate to lift the rack 30. After repeating the above operations to make the nozzle 10 reach an appropriate height, the adjustment handle 16 resets under the action of the torsion spring 18, and the stabilizing frame 34 also resets under the action of the second spring 41 and the third spring 42. The clamping strip 48 loses the restriction and is clamped to the rack 30 to prevent the rack 30 from moving and causing the height to change;

[0066] When the height of the nozzle 10 needs to be lowered, press the adjustment handle 16, drive the stabilizing frame 34 to make the clamping strip 48 release the restriction on the rack 30, press down the horizontally installed plate 11, drive the rack 30 to move downward. Due to the first ratchet wheel 23 and the second ratchet wheel 24, and a first spring 33 is arranged between the second ratchet wheel 24 and the adjustment disc 31. At this time, the first spring 33 will be compressed, and the second ratchet wheel 24 moves towards the adjustment disc 31. The first ratchet wheel 23 and the second ratchet wheel 24 are no longer meshed, that is, the stillness of the toothed plate 19 and the first gear 20 will not affect the downward movement of the rack 30;

[0067] By adjusting the height of the nozzle 10, the mismatch of liquid medicine spraying at the same height for plants in different growth periods is avoided, the problem that the liquid medicine cannot fully act on the plants is avoided, the liquid medicine is saved, and the waste of the liquid medicine is avoided.

[0068] Example 3

[0069] Please refer to Figure 8 , on the basis of Embodiments 1-2, a longitudinal mounting plate 8 is fixedly connected to the transverse mounting plate 11, an angle adjustment assembly 9 is fixedly connected to the longitudinal mounting plate 8, the angle adjustment assembly 9 includes a fixed rotating support 51, the fixed rotating support 51 is fixedly connected to the longitudinal mounting plate 8, a fourth rotating shaft 52 is rotatably connected to the fixed rotating support 51, a movable rotating support 54 is fixedly connected to the fourth rotating shaft 52, and a nozzle 10 is fixedly connected to the movable rotating support 54;

[0073] The working principle and beneficial effects of the above solution:

[0074] Pull the handle 58, the five springs 57 contract, the clamping block 56 is disengaged from the chuck 53, the rotation of the chuck 53 is no longer restricted, rotate the movable rotating support 54 to drive the nozzle 10 to rotate, so that the spraying angle of the nozzle 10 can adapt to different plant row spacings, and can better adapt to different use scenarios. For example, in the scenario of intercropping corn and soybeans, the spacing between soybeans is different from the spacing between corn and soybeans, and spraying at the same spacing cannot meet this requirement. By changing the spraying angle, the sprayed liquid medicine can act on plants with different spacings, avoiding the waste of the liquid medicine.
