Example 2: as shown in fig. 6, the method for operating the anti-drift drug delivery device provided in embodiment 1 includes the following steps:

The main factors influencing the drift rate of the fog drops include spraying pressure and auxiliary airflow speed, when the motor rotation speed is 1200r/min, the average wind speed of the air outlet channel is 6m/s, when the motor rotation speed is 1800r/min, the average wind speed of the air outlet channel is 10m/s, and when the motor rotation speed is 2600r/min, the average wind speed of the air outlet channel is 15m/s; by configuring the motor with three speeds: 2600r/min, 1800r/min and 1200r/min, and auxiliary air flow speeds of 15m/s, 10m/s and 6m/s can be respectively obtained.
When the ambient wind speed is less than 3.5m/s, the rotating speed of the centrifugal fan is set to be 6m/s.
When the ambient air speed is between 3.5m/s and 4.5m/s, the particle size of the fog drops is reduced under the action of auxiliary air flow, the movement speed of the fog drops is increased, the fog drops can rapidly move to the target surface, when the auxiliary air flow speed is 6-10 m/s, the drift of the fog drops can be effectively reduced, when the auxiliary air flow speed exceeds 10m/s, the drift prevention effect of the fog drops is obviously reduced, and in this case, the rotating speed of the centrifugal fan is set to be 10m/s, and the drift is gradually reduced within the effective range.
When the ambient wind speed exceeds 4.5m/s, the drift reducing effect is significantly reduced, and in order to prevent the amount of drift from being excessively large in this case, the rotational speed of the centrifugal fan is set to 15m/s.
When the wind speed reaches the surface of the crops, the speed is not higher than 8m/s and cannot be too low, and when the wind speed reaches 2m/s, the turning of the crops is not obvious. Under the action of auxiliary air flow, the particle size of the fog drops is reduced, the movement speed of the fog drops is increased, and the fog drops can move to the surface of a target rapidly. When the auxiliary air flow speed is 0-10 m/s, the drift of the fog drops can be effectively reduced, and when the auxiliary air flow speed exceeds 10m/s, the drift prevention effect of the fog drops is obviously reduced. The anti-floating effect is better when the auxiliary air flow speed is 15m/s and the ambient air speed is about 4.5m/s, and the anti-floating effect is better when the auxiliary air flow speed is 10m/s and the air speed is 3.5 m/s.
Aiming at the measurement of the drift threshold, a fog drop deposition monitoring sensor network system researched by the national academy of sciences of agriculture and forestry in Beijing is adopted, the system senses the concentration of fog drops by using a blade humidity sensor and outputs analog quantity signals, and then the fog drop deposition monitoring sensor network system acquires analog data to obtain the fog drop drift rate and control the fog drop drift rate correspondingly.
By measuring different spray pressures and drift conditions in the case of external wind speed, the spray pressure of 0.5MPa, the air flow speed of 30 m/s and the natural wind of 3.5m/s can be obtained, and the drift prevention effect is best.
As described above, although the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

6. The anti-drift delivery device of claim 4, wherein: the motor support top is equipped with hangs connecting portion, it is connected with the horizontal pole to hang connecting portion, the motor support can be followed the horizontal pole and removed so that prevent drifting and administer the medicine device lateral deviation.
7. A method of operation using the anti-drift applicator of claim 5, comprising the steps of:
s1: setting a drift threshold;
s2: acquiring wind speed and wind direction in the current environment, if the wind speed and wind direction meet the operation conditions, entering S3, and if the wind speed and wind direction do not meet the operation conditions, stopping operation;
s3: performing anti-drift control, setting the rotating speed of the motor according to the wind speed, and setting the angle of the guide cover according to the wind direction;
s4: performing spray head control, and setting spray head pressure according to the travelling speed;
s5: and collecting a current drift value, if the drift rate of the fog drops is lower than or equal to a set drift threshold value, continuing to operate, and if the drift rate of the fog drops is higher than the set drift threshold value, repeatedly executing S4 and S5 until the drift rate of the fog drops is lower than or equal to the set drift threshold value.
8. The method of operating an anti-drift applicator of claim 7, wherein: and (2) stopping working when the ambient wind speed obtained in the step (S2) exceeds 5m/S or the ambient wind direction exceeds 45 degrees in the forward direction and the backward direction.
9. The method of operating an anti-drift applicator of claim 7, wherein: dividing the ambient wind speed into a low wind speed interval, a medium wind speed interval and a high wind speed interval, wherein the motor is provided with a high-rotating-speed, medium-rotating-speed and low-rotating-speed adjustable gear, and a high auxiliary air flow speed, a medium auxiliary air flow speed and a low auxiliary air flow speed are respectively formed in the air outlet channel corresponding to the high-rotating-speed, the medium-rotating-speed and the low rotating-speed; in the step S2: when the acquired ambient wind speed is located in a low wind speed interval, setting the rotating speed of the motor to be a low rotating speed so as to form a low auxiliary airflow speed in the air outlet channel; when the acquired ambient wind speed is in a wind speed interval, setting the rotating speed of the motor to be a medium speed so as to assist the airflow speed in the formation of the wind outlet channel; when the acquired ambient wind speed is located in a high wind speed zone, setting the rotating speed of the motor to be high so as to form high auxiliary airflow speed in the air outlet channel;
dividing the environmental wind direction into a front wind direction section, a middle wind direction section and a rear wind speed section, wherein in the step S2: when the acquired ambient wind direction is located in a front wind direction zone, the motor push rod drives the guide cover to rotate forwards; when the acquired ambient wind direction is positioned in a front wind direction section, the guide cover is kept at a default angle and is not adjusted; when the acquired ambient wind direction is positioned in the rear wind direction section, the motor push rod drives the guide cover to rotate backwards.
10. The method of operating an anti-drift applicator of claim 7, wherein: the drift threshold is set to be 30%, the drift threshold is measured through a blade humidity sensor and a droplet deposition monitoring sensor network system, the blade humidity sensor senses the concentration of the droplet and outputs an analog signal, and the analog signal can be processed by the droplet deposition monitoring sensor network system to generate the drift threshold.
