Abstract
The utility model relates to an improvement on air-mixing spray-nozzle structure used to spray insecticide, and belongs to the technical field of plant protection facility. The spray-nozzle comprises a spray head body whose front end is equipped with a spray-nozzle, the back end of the spray head body is provided with a water inlet, and the middle part of the spray head body is provided with a reducing section with air holes. An air-liquid mixing chamber is formed between the reducing section and the spray-nozzle. The improvement is that: the reducing section is connected with the air-liquid mixing chamber through a divergent port, and a step column connection is formed between the air-liquid mixing chamber and the spray-nozzle. When the utility model is used, the air is sucked into the air-liquid mixing chamber through the divergent port while the physic liquid crosses through the jet flow accelerating section of the reducing section, and then the physic liquid and the air are mixed. Then the mixture is compressed to form into float resistant big drops, and these big drops are full filled with air bubbles. After the drops is ejected from the spray nozzle, the air bubbles swell to make the drops accelerate, and when the drops hit the target drones, the big drops is broken into small drops. The small drops have good covering effect, which improves the service efficiency of the agricultural chemical.
Description
Technical field
The utility model relates to a kind of nozzle, and especially a kind of air-mixing nozzle architecture advances that is used to spray insecticide belongs to plant protection facility technology field.
Background technology
In the pesticide spraying and after spraying, drift aloft is called spray drift to the phenomenon beyond the non-target zones.Spray drift causes: the invalid use of application equipment and spraying time; The sensitive crop in adjacent plot is impaired; Waste agricultural chemicals, reduction prevention effect increase the control number of times, increase cost; For the offset drift loss, guarantee preventive effect, certainly will cause excessive spray medicine; Residues of pesticides exceed standard and cause grain contamination; Cause air and pollution of waterhead.The factor that causes drifting about mainly contains: the spraying droplet size; Sprayer unit and application technique; Meteorologic factor etc.
Nearly 10 years, the research to spray drift abroad obtained remarkable progress.Done many work on flusher and spray means, under suitable meteorological condition, except adopting protective cover, strength assistant spray technology smears etc. outside the method, and the means of topmost control drift just are to use novel low drift shower nozzle.
Understand according to the applicant, two kinds of typical low drift shower nozzles are abroad arranged at present.A kind of Raindrop nozzle that is called as, its design feature is to add a preposition overcurrent chamber above common nozzle, liquid enters the overcurrent chamber through the aperture in overcurrent chamber during operation, enter sprayer body then, spray through spout, because rate of flow of fluid can fall in the overcurrent chamber, therefore the spectrum of fog drop of shower nozzle is narrowed down.Shower nozzle only produces big droplet like this, less than 30 μ m droplet numbers seldom, thereby reaches the purpose that reduces drift.Another kind is the mixed shower nozzle of so-called Turbodrop jetting type air, and it utilizes jet current principle, sucks air when soup process jet accelerating region, in the mixed flow section, soup and air mix, and form the big droplet of anti-drift again by spout, thereby improve the agricultural chemicals service efficiency.
Discover,, still might further improve the effect that suppresses drift by above prior art is improved.
Summary of the invention
The technical problem that will solve of the present utility model is: propose a kind of simple in structure, can further improve the jetting type air-mixing nozzle that suppresses the drift action effect.
In order to solve above technical problem, jetting type air-mixing nozzle of the present utility model comprises that front end is shaped on the sprayer body of nozzle, the rear end of described sprayer body is a water inlet, the middle part is for being shaped on the undergauge section of air admission hole, form the gas-liquid mixed chamber between described undergauge section and the nozzle, its improvements are: be connected by the flaring mouth between described undergauge section and the gas-liquid mixed chamber, form the step cylinder between described gas-liquid mixed chamber and the nozzle and be connected.
During use, when soup passes through the jet accelerating sections of undergauge, flow velocity increases pressure and reduces, thereby suction air, enter behind the gas-liquid mixed chamber through the flaring mouth, flow velocity reduces pressure and increases, and soup and air mix, then be compressed, form the big droplet of anti-drift by spout, and air bubble abrim in these big droplets, after droplet sprays from nozzle, air bubble expansion, droplet is quickened, and after droplet hit target, big droplet explosion formed little droplet, little droplet forms good covering, has further improved the agricultural chemicals service efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
The jetting type air-mixing nozzle of present embodiment as shown in Figure 1, sprayer body is made up of sprayer body overcoat 3 that is threaded by port and sprayer body inner core 4.Front end is shaped on nozzle 9, and the rear end is a water inlet 2, and the middle part is the undergauge section 6 that is shaped on air admission hole 5.Water inlet 2 is communicated with by hole 1, thin footpath with undergauge section 6.Form gas-liquid mixed chamber 8 between undergauge section 6 and the nozzle 9.Be connected by flaring mouth 7 between undergauge section 6 and the gas-liquid mixed chamber 8, the step column structure by the diameter sudden change between gas-liquid mixed chamber 8 and the nozzle 9 is connected.
When soup by water inlet 2 through hole 1, thin footpath during to the jet accelerating sections 6 of undergauge, pressure obviously reduces because of flow velocity increases sharply, thereby suck air by air admission hole 5, enter behind the gas-liquid mixed chamber through flaring mouth 7, flow velocity reduces gradually, and pressure increases, and soup and air fully mix, then compressed rapidly, form anti-drifts and be full of the big droplet of air bubble by spout 9.After big droplet sprayed from nozzle, air bubble expansion quickened droplet, and after droplet hit target, big droplet explosion formed little droplet, formed well to cover, and had significantly improved the agricultural chemicals service efficiency.
In brief, this special atomizing type makes on the one hand droplet in leaving the process that nozzle flies to target, has than major diameter, has reduced drift; On the other hand, after droplet drops on the target, form little droplet, improved covering quality.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
