(5) The fog drops in the front and back directions are prevented from floating: the battery 605 supplies power to a fan (not shown in the figure) inside the air duct 103, and the air flow is sucked from the air inlets of the front wind power adjusting device 105 and the rear wind power adjusting device 108 and flows out of the middle wind power adjusting device 107.

The air inlets of the front wind power adjusting device 105 and the rear wind power adjusting device 108 can form a front wind curtain and a rear wind curtain, so that on one hand, the influence of the wind speed of the external environment on fog drops is blocked, on the other hand, fine fog drops suspended in the air can be sucked, the drifting is reduced, further sucked fine fog drops are adsorbed on the front electrostatic network 109 and the rear electrostatic network 110, the number of the fine fog drops adsorbed on the front electrostatic network 109 and the rear electrostatic network 110 is increased and gathered to form large fog drops, and the air flow field and the electrostatic field are not enough to support the weight of the large fog drops, so that the large fog drops fall on a spraying area, and the effective utilization of pesticides is realized; the air outlet of the medium wind power adjusting device 107 can wrap and spray the fog drops into the crop canopy on one hand, and on the other hand, the influence of the external environment on the fog drops can be reduced.

In addition, due to the change of the external environment, the growth height of crops and the thickness of a canopy, the speed and the direction of the air flow required to be sucked are different from those of the air flow flowing out, and if the speed and the direction of the air flow sucked by the front wind power adjusting device 105 and the rear wind power adjusting device 108 are not matched with the growth height of crops, the thickness of the canopy and the like, on one hand, the small fog drops in the air cannot be completely adsorbed, and on the other hand, the formed air curtain cannot block the influence of the external wind speed; if the speed and direction of the air flow flowing out from the wind power adjusting device 107 are not matched with the growth height of crops, the thickness of the canopy and the like, on one hand, the fog drops can not be accurately sprayed on the target, and on the other hand, the air flow can not be accurately matched with the size of the fog drops and the information of the crops. A control system (not shown in the figure) of the spraying machine detects the height and the canopy density of the soybean according to a first laser radar (not shown in the figure), detects the height and the canopy density of the corn according to a second laser radar (not shown in the figure), detects the ambient wind speed and the ambient wind direction according to a first wind speed sensor (not shown in the figure), detects the wind speed and the wind direction of a wind port of each wind power adjusting device according to a second wind speed sensor (not shown in the figure), and combines a prophase test data model to change the wind speed and the wind direction.

The wind adjustment device 105 is taken as an example to illustrate the wind direction change: the first motor 10503 is fixed on the front wind belt 104, the first motor 10503 drives the second gear 10502 to rotate, the second gear 10502 drives the first gear 10501 to rotate, the first gear 10501 is fixed on the first rotating shaft 10506, the first rotating shaft 10506 is fixed with the first rotating plate 10505, so that the first rotating plate 10505 can be driven to rotate, the first rotating plate 10505 further pushes the fixing plate 10504, the fixing plate 10504 pushes the second rotating plate 10510 to rotate around the axis of the third rotating shaft 10509, and the second motor 10516 has a self-locking function, so that the front plate 10511 and the rear plate 10518 cannot rotate freely when the second motor 10516 does not give out indication, and the second rotating plate 10510 and the first rotating plate 10505 respectively drive the front plate 10511 and the rear plate 10518 to rotate around the third rotating shaft 10509 and the first rotating shaft 10506, and meanwhile, the first soft curtain 10507 and the second soft curtain 10513 are made of flexible materials, so that the movement of each part cannot be limited, and the change of the wind direction can be realized.

The wind speed change can be realized by adjusting the rotation speed of a fan (not shown in the figure) inside the wind duct 103 to realize the integral change of the wind speeds of the air inlets of the front wind power adjusting device 105 and the rear wind power adjusting device 108 and the air outlet of the middle wind power adjusting device 107, because the wind speeds required by the air inlets of the front wind power adjusting device 105 and the rear wind power adjusting device 108 and the air outlet of the middle wind power adjusting device 107 are different, the area sizes of the air inlets of the front wind power adjusting device 105 and the rear wind power adjusting device 108 and the air outlet of the middle wind power adjusting device 107 need to be changed to realize the difference of the wind speeds, the wind speed change under the condition of not changing the rotation speed of the fan is illustrated by the wind power adjusting device 105 in the past: the motor two 10516 is installed on the fixed plate 10504, the motor two 10516 drives the gear five 10515, the gear five 10515 drives the gear four 10514, the gear four 10514 drives the gear three 10512, the gear four 10514 and the gear three 10512 are respectively fixed on the rotating shaft four 10517 and the rotating shaft two 10508, the rotating shaft four 10517 and the rotating shaft two 10508 are respectively fixed with the rear plate 10518 and the front plate 10511, so that the rear plate 10518 and the front plate 10511 can rotate around the axes thereof, and the change of the area size of the air outlet is achieved.

(6) And mist drops between rows and above the rows are prevented from floating: the fog drops sprayed by the left spray rod 507, the middle spray rod 603 and the right spray rod 707 cannot be sprayed on adjacent crops (namely, pesticide sprayed on soybeans cannot reach the corns, and pesticide sprayed on the corns cannot reach the soybeans) under the common blocking action of the first baffle 401, the second baffle 403, the third baffle 405 and the fourth baffle 407; meanwhile, under the combined action of the first cover plate 402, the second cover plate 404 and the third cover plate 406, the fog drops cannot fly from the upper part.

It should be noted that modifications and adaptations can be made by those skilled in the art without departing from the principle of the present invention, and should be considered as within the scope of the present invention. All the components not specified in the present embodiment can be realized by the prior art.
