With reference to fig. 4, before the operation, the relative positions of the upper support 33 and the lower support 30 can be adjusted according to the height of the sprayed plants, when facing low plants, the upper support can be horizontally placed for near-ground spraying, and when facing higher plants, the upper support can be vertically placed or obliquely placed for high-plant profiling spraying; in the case of near-ground spraying, a low-pressure anti-floating liquid medicine recovery system can be installed on the upper bracket 33, the installation position needs to be adjusted according to actual conditions, and at the moment, a replaceable baffle plate 38 matched with the multi-degree-of-freedom spray rod mechanism needs to be installed above the outer portion of the baffle plate 18.
Referring to fig. 5, in the movable bracket 15, the upper bracket 33 and the lower bracket 30 may be respectively provided with a plurality of multi-degree-of-freedom motion unit groups 14, and the number of the multi-degree-of-freedom motion unit groups 14 is adjusted by specific factors such as a spraying mode, a spraying width of the electrostatic nozzle 19, a spraying position, and the like. When the multi-degree-of-freedom spray rod mechanism carries out high-plant profiling spraying, the inclination angle of the upper support 33, the position of the multi-degree-of-freedom motion unit group 14 and the spraying angle of the electrostatic spray head 19 can be adjusted, high-precision profiling spraying is carried out, and the spraying effect can be further improved by combining technologies such as precise spraying and the like.
Referring to fig. 6, in the operation of the horizontal spraying mechanism, the U-shaped baffle 18 is always covered above the plant, the plant enters the spraying area from the inlet 37 of the baffle, leaves the low-pressure anti-floating liquid medicine recovery system from the tail 36 of the baffle, and a replaceable baffle plate 38 matched with the horizontal spraying mechanism is required to be installed above the outer part of the baffle 18; the liquid drops sprayed by the electrostatic spray head 19 are fully deposited on the weed blades after a period of time, and the liquid drops which are not deposited in the air are sucked by the air inlet 17; because the diameter of the inner wall of the middle near-ground air inlet 35 is smaller than that of the tail near-ground air inlet 34, the air flow of the middle near-ground air inlet 35 is smaller than that of the tail near-ground air inlet 34, and the horizontal spray rod is bent in a certain radian, so that the distance between the electrostatic spray head 19 and the middle near-ground air inlet 35 is optimized, the absorbed amount of liquid medicine droplets in the air at the middle near-ground air inlet 35 is less, the liquid medicine droplets are completely absorbed at the tail near-ground air inlet 34, the deposition of the liquid medicine droplets on weed blades is ensured to be more sufficient, and the pesticide application effect can be improved. Because air inlet 17 takes out the inside air of baffle 18 for the inside atmospheric pressure of baffle 18 is lower than the external world, can prevent effectively that the inside liquid droplet of baffle 18 from drifting, endangers other plants. Due to the low air pressure inside the baffle 18, wind in a direction parallel to the baffle 18 to some extent can be resisted, and the wind speed can be resisted in relation to the maximum air flow of the air inlet 17. When the wind speed is not more than the maximum suction amount of the air inlet, the low-pressure anti-floating liquid medicine recovery system can normally operate. Horizontal spray lance level is placed, is certain radian and crooked to baffle afterbody 36, and crooked radian formulates according to actual need, can increase electrostatic spray 19 and the nearly ground air inlet 35's in middle part distance under the prerequisite of guaranteeing that liquid medicine droplet can not follow the entry and overflow, and furthest reduces the low pressure and prevents floating liquid medicine recovery system and to the deposited influence of liquid droplet, improves the effect of giving medicine to poor free of charge, also can reduce U type baffle 18's longitudinal distance, improves spraying machine's flexibility.
Referring to fig. 7, the inner side of the rectangular opening of the baffle 18 is provided with a groove for installing the replaceable baffle piece 38, and the replaceable baffle piece 38 is pushed in from one side during installation.
Referring to fig. 8, the alternative baffle plate 38 is a flat cuboid, which is provided with holes and rounded corners, and has no special requirement for the quality of the baffle plate; the replaceable baffle plate 38 is only matched with the electrostatic spray heads 19 with one size and the spray rod, holes are formed in the replaceable baffle plate 38, the diameter of each hole is the same as that of the matched electrostatic spray heads 19, and the distribution of the holes corresponds to the distribution direction of the electrostatic spray heads on the matched spray rod.
