In this way, the first nozzle 320 and the second nozzle 420 can be shifted by a certain distance.

As an example, in the advancing direction of the body 11, the first nozzle 320 is located at the right side of the body 11 and is disposed toward the left side of the body 11, and the second nozzle 420 is located at the left side of the body 11 and is disposed toward the right side of the body 11.

Referring to fig. 10 and 11, in the present embodiment, the spray incidence angle of the first spray head 320 and the second spray head 420 is greater than or equal to 60 °. It should be noted that, the spraying incidence angle refers to an angle between a center line of the spray head and a forward direction (denoted by L in the drawing) of the machine body 11, or in an actual application scenario, the spraying incidence angle may be an angle between the center line of the spray head and a plant alignment direction. As an example, the spray incidence angle θ1 of the first spray head 320 refers to an angle between a center line of the first spray head 320 and a forward direction (denoted by L in the drawing) of the body 11; the spray incidence angle θ2 of the second nozzle 420 is an angle between a center line of the second nozzle 420 and a forward direction (indicated by L in the drawing) of the body 11. The spray incidence angle θ1 of the first nozzle 320 and the spray incidence angle θ2 of the second nozzle 420 may be equal, for example, may be greater than or equal to 60 °. Further, the spray incidence angle may be 90 ° according to discrete particle drift mechanics and hydrodynamic principles. In addition, considering that the first and

second sprayers

320 and 420 may alternatively use high pressure nozzles in the present embodiment, two forms may be adopted: the hollow cone spray head and the fan-shaped spray head can spray atomized fog drops, and then a certain distance is achieved to form a wide-range covering effect. And is for example around 700mm wide due to the narrow paths between rose clusters in the spray scene. In order to enlarge the atomization distance, the atomization range is sufficiently large, and the spraying incidence angle θ1 of the first nozzle 320 and the spraying incidence angle θ2 of the second nozzle 420 are both 90 degrees, namely θ1=θ2=90 degrees, so that the effective kinetic energy rate of atomized particles is improved, and the drug mist permeability is increased.
