Abstract
The invention provides a device for preventing and reducing spray drift, comprising flexible fiber yarns which are arranged on nozzles of a spray device and have the length of 5 to 50 cm, and the flexible fiber yarns are connected to fiber yarn fixing heads. The fiber yarn fixing heads are arranged at the at least one of front, rear, left and right directions of the nozzles. According to the device provided by the invention, the flexible fiber yarns are fixed on one side of the nozzles, and the flexible fiber yarns form a check curtain for prolonging airflow. The droplets of the spray nozzles can be spread out more uniformly by a turbulence eddy of the high-pressure airflow of the spray nozzles and the outside wind current, and the collision and adhesion between the droplets are reduced, meanwhile the possibility that small droplets with good atomization effect change into large droplets with poor pesticide effect is also reduced. Since the droplets with good dispersion quality are obtained by eddy current, the ability of the droplets being adsorbed on the surface of the crop leaves can be increased, and the pesticide effect can be better played.
Description
Technical field
The invention belongs to agricultural machinery technological field, be specifically related to machinery and the method for a kind of applying pesticides.
Background technology
Drift is that pesticide is in use by the air phenomenon to non-predetermined target travel.In most of the cases,
Drift is only limitted to field edge or protection row, but in the case of special dispenser, drift athletic meeting impact is from the far crop of field
Or resident.Flight drift refers to that pesticide droplet flies away from the physical motion process of target, main and Pesticide use method and the machine of use
There is pass.China's Pesticide use amount of a year the most about 300,000 tons, but because drift loss, the pesticide sprayed away only has few portion
Assign to and reach on target.
The most relatively advanced pesticide application technology is to use low capacity width spraying swath to spray machinery, and for different crops with not
Same Agent spraying machine and dosage form are sprayed.But because in prior art, Agent spraying machine automaticity is the highest, use Large Copacity spray
The factors such as mist, flusher kind are single, cause the effective rate of utilization of pesticide to only have about 20%, cause the wave of a large amount of pesticide
Take.
Summary of the invention
The weak point existed for this area, an object of the present invention is to propose a kind of anti-dress subtracting spray medicine drift
Put.
Second object of the present invention is to propose a kind of anti-method subtracting spray medicine drift.
Realizing the object of the invention technical scheme is:
A kind of anti-device subtracting spray medicine drift, it includes the flexible fiber silk being arranged on the nozzle of spray medicine equipment, described
A length of the 5 of flexible fiber silk～50cm.

Part connects.
A kind of anti-method subtracting spray medicine drift, comprises the following steps:
The first step is selected: measured wind speed before dispenser, calculates nozzle bore, selected nozzle；
Second step is to calculate: determine dispenser height, calculates dispenser angle, the selected length of flexible fiber silk, quantity；
3rd step is Simulation evaluation: measure the little eddy current of wind field, calculates drift and reduces coefficient, meets and then simulates calculating when requiring
Dispenser consumption, draws the most anti-coefficient that wafts, to evaluate the anti-effect subtracting spray medicine drift；It is discontented with if the drift calculated reduces coefficient
Foot requirement, then revise dispenser height and dispenser angle, is again simulated evaluating.
In 3rd step, drift reduces coefficient and can be understood as fixed position point such as 10 meters, level altitude such as 1.8 meters
(different plants, highly different), calculate and commonly spray at same sampling location (not setting flexible fiber silk) and present invention spraying
Drift value difference is divided by the ratio of common drift value.Typically it is considered as meeting requirement when this ratio reaches 20-30%, selects " Y ".
The anti-coefficient that wafts is the drift value ratio divided by drift distance.
Nozzle bore can use formula (1) to calculate:
D={q ÷ (0.658 × p1/2×n)}1/2×η (1)
Wherein, in described 3rd step, gather drift value, in order to evaluate at distance nozzle 2～100 meters of position water sensitive paper
The anti-effect subtracting spray medicine drift.
Distribution character for flight drift pesticide droplet, it is preferable that at 5 meters of nozzle of distance, 10 meters, 15 meters of positions are used
Water sensitive paper gathers drift value, in order to evaluate the anti-effect subtracting spray medicine drift.
Wherein, in described 3rd step, detect strength of vortex with detector, by controlling device, then adjustable spraying nozzle
Expulsion pressure so that expulsion pressure is corresponding with strength of vortex change, at utmost utilizes eddy current to reduce drift.
The beneficial effects of the present invention is:
The device that the present invention proposes, is fixed on the side of nozzle by flexible fiber silk, and flexible fiber silk is formed and extends air-flow
Check apron；On the one hand the high pressure draught of spray nozzle and the turbulent eddy current that the external world is distinguished and admirable are utilized so that the droplet of nozzle can be more equal
Even scatter, and reduces the collision between droplet and adhesion, reduces the good little droplet of atomization and becomes the big droplet that drug effect is very poor
Ratio.Owing to by obtaining the good droplet of dust dispersion quality after eddy current, adding the droplet absorption energy on crop leaf surface
Power, can preferably play drug effect.
Flexible fiber silk contacts with plant top vane, during spraying machine advances, smears at plant surface brush always,
What on the one hand droplet can be scraped by flexible fiber silk is more uniform, and on the other hand flexible fiber silk will not damage crops.
