[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A spraying device includes a spraying frame 5 and two connecting frames 1, the two connecting frames 1 are symmetrically installed on the vehicle body, and the spraying frame 5 is located between the two connecting frames 1, the interior of the spraying frame 5 is hollow, and a plurality of supporting keels 7 are arranged in the middle of the spraying frame 5.

[0022] The interior of the spray rack 5 is hollow and is used for conveying liquid medicine. The spray rack 5 is connected to the liquid supply box through a hose and is externally connected to a pump body. With continuous conveying pressure, the liquid medicine is sprayed out from the high-pressure nozzle 6. At the same time, the connecting frame 1 is installed on the vehicle frame and moves between the ridges with the agricultural vehicle. This part is the existing technology and will not be elaborated here.

[0023] The widths of ridges in different areas are different, and the height of traditional nozzles cannot be adjusted, so that the crop area covered by a single high-pressure nozzle 6 is a fixed value. When the spraying area increases, it is often necessary for the agricultural vehicle to reciprocate multiple times to cover and spray the crops.

[0024] A plurality of high-pressure nozzles 6 are evenly installed at the bottom of the spraying rack 5, and the high-pressure nozzles 6 are connected to the pump body through a pipeline. A sliding assembly is provided on the upper part of the connecting frame 1, and two support plates 8 are slidably provided through the sliding assembly. A plurality of pads 9 are evenly distributed on the opposite side of the two support plates 8 in the longitudinal direction. A limit frame 10 is extended from the side wall of the spraying rack 5, and the limit frame 10 is clamped between the upper ends of the two pads 9;

[0025] The support plate 8 is fixed on the connecting frame 1 through a fastening structure.

[0026] The sliding assembly includes a base 11, a track 12 and a slider 2. The slider 2 is connected to the lower end of the base 11, the base 11 slides on the upper end of the connecting frame 1, the track 12 is opened on the upper part of the connecting frame 1, the slider 2 is slidably set on the inner side of the track 12, and the slider 2 and the track 12 cooperate with each other.

[0027] The fastening structure includes a fastening bolt 3 and a threaded hole 4. The threaded hole 4 is provided on one side of the upper end of the connecting frame 1 close to the limiting frame 10. The fastening bolt 3 penetrates the base 11 and extends into the threaded hole 4 to fix the base 11.

[0028] When the limiting frame 10 is located between the two supporting plates 8 , both upper and lower end surfaces of the limiting frame 10 are in contact with the pad 9 .

[0029] When adjusting the height of the high-pressure sprinkler 6, the spray rack 5 is adjusted to an appropriate height by a lifting device or a jack, and the support plate 8 on the connecting frame 1 is moved closer to the spray rack 5. During the approach, the slider 2 at the lower end of the base 11 slides in the track 12. When the limit frame 10 on one side of the spray rack 5 is inserted into the inner side of the pad 9 on one side of the support plate 8, the fastening bolts 3 and the threaded holes 4 are matched with each other to fix the base 11 and the support plate 8. Secondly, the width of the spray rack 5 is greater than the width of the limit frame 10, so that after the spray rack 5 is fixed between the support plates 8 on both sides, the support plates 8 have an obstructive effect on the lateral movement of the spray rack 5, and no lateral movement will occur. The pads 9 are distributed longitudinally on the support plates 8. In this way, the height adjustment of the high-pressure sprinkler 6 can be effectively achieved, and then the range of its spraying can be adjusted.

[0030] The working principle of the device is:

[0031] The interior of the spray rack 5 is hollow and is used for conveying liquid medicine. The spray rack 5 is connected to the liquid supply box through a hose and is externally connected to a pump body. With continuous conveying pressure, the liquid medicine is sprayed out from the high-pressure nozzle 6. At the same time, the connecting frame 1 is installed on the vehicle frame and moves between the ridges with the agricultural vehicle. This part is the existing technology and will not be elaborated here.

[0032] The width of the ridges in different areas is different, and the height of the traditional nozzle cannot be adjusted, so the crop area covered by a single high-pressure nozzle 6 is a fixed value. When the spraying area increases, it often takes multiple reciprocating movements of the agricultural vehicle to cover and spray the crops.

[0033] To this end, when adjusting the height of the high-pressure nozzle 6, the spray rack 5 is adjusted to an appropriate height by a lifting device or a jack, and the support plate 8 on the connecting frame 1 is moved closer to the spray rack 5. During the approach, the slider 2 at the lower end of the base 11 slides in the track 12. When the limit frame 10 on one side of the spray rack 5 is inserted into the inner side of the pad 9 on one side of the support plate 8, the fastening bolts 3 and the threaded holes 4 are matched with each other to fix the base 11 and the support plate 8. Secondly, the width of the spray rack 5 is greater than the width of the limit frame 10, so that after the spray rack 5 is fixed between the support plates 8 on both sides, the support plates 8 have an obstructive effect on the lateral movement of the spray rack 5, and no lateral movement will occur. The pads 9 are distributed longitudinally on the support plates 8. In this way, the height adjustment of the high-pressure nozzle 6 can be effectively achieved, and then the range of its spraying can be adjusted.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
