Description

Self-excitation liquidates fog spray head
Technical field
The invention belongs to field of plant protection machine, are related to a kind of fine-tuning variable-flow nozzle, more particularly to one kind can improve The self-excitation of the mist droplet particle size uniformity liquidates fog spray head.
Background technology
The nozzle of equipment for plant protection is the critical component in equipment for plant protection, is the atomising device of liquid, the quality of performance Determine that formulation rate, droplet size and uniformity in spray process etc. weighs the critical index such as atomization quality.Plant protection is sprayed Head is also the key for improving pesticide application technology.Therefore, research plant protection nozzle to equipment for plant protection, pesticide application technology towards accurate, low amounts, High concentration development has important meaning.It being required according to the sprinkling of pesticide, the size of droplet is a critically important performance parameter, it Be related to the medicament that nozzle sprays out penetrate and carrying capacity, and influence plant surface to " the intercepting and capturing rate " of droplet and Drift caused by covering uniformity, completeness and medicament on plant surface.Particle size uniformity is to weigh pulverability quality One important indicator.
Invention content
The technical problem to be solved by the present invention is to：For the bad control of nozzle spraying droplet particle size uniformity in the prior art The technical issues of system, atomization quality cannot be guaranteed.
The purpose of the present invention is to provide a kind of raising atomization quality and nebulization efficiency, improve liquid particle size uniformity oneself Swash the fog spray head that liquidates.
The design philosophy of the present invention, liquid is after nozzle at high speeds is injected in air, due to aerodynamic force, inertia force, viscous force With the interaction of the various power such as surface tension, fluid column breakup becomes different discrete bolus.Based on collision mode It realizes that breakup of drop theory and injection stream are theoretical, is mutually hit by flow and obtain smaller liquid-drop diameter, as shown in Figure 1, mainstream hole The injection liquid ejected homed on its target object in an axial direction, the jet stream that both sides discharge orifice sprays with axis direction due to having certain cone angle meeting Power stream liquid is impacted at a certain distance from liquid is from nozzle mouth, the injection stream for forming liquid is mutually hit, the punching of both sides discharge orifice jet stream Power stream is hit, spraying is made to divide again；Additionally, due between effluent hole injection stream and mainstream hole injection stream, there are air, in two sprays Jet hit areas adjacent forms certain vortex, and the pneumatic interaction between high-speed jet and ambient gas causes liquid level unstable Determine and rupture, further crushes drop under air self-oscillation effect, improve atomization quality.
In order to solve the above technical problems, the specific technical solution that the present invention uses is：
A kind of self-excitation liquidates fog spray head, including nozzle cover, sprinkler cap, elastic sealing gasket, spray core, spray nozzle sheet, pressure cap and spray Pipe；
Pressure cap setting is arranged in nozzle-end, spray nozzle sheet on pressure cap, and spray core is arranged on spray nozzle sheet, and sprinkler cap passes through bullet Property gasket is sleeved in spray core, nozzle cover connecting spray nozzle and by sprinkler cap, elastic sealing gasket, spray core, spray nozzle sheet and pressure cap pressure Tightly on jet pipe；
Bellmouth is arranged in the central shaft of sprinkler cap, and the small end of bellmouth is spray outlet；
Spray core is constituted by bottom plate and with the matched spraying cone of sprinkler cap bellmouth；Mainstream hole and not is set on bottom plate Effluent hole less than one, mainstream hole are located on the central shaft of bottom plate, and effluent hole is located at the surrounding in mainstream hole；It is sprayed in effluent hole The acute angle that an angular range is 30 ° -80 ° is formed in liquid axis and mainstream hole between ejection liquid axis；
The central axis in bottom plate is arranged in spraying cone in spray core, and one circle of root setting of spraying cone is for installing bullet Property gasket annular region, setting and the one-to-one spray cistern in effluent hole, spray cistern and effluent on the side wall of spraying cone Hole communicates；The top indent of spraying cone is arranged " V " font cambered-surface fan-shaped spray outlet, at center setting communicated with mainstream hole " V " font inclined-plane spray outlet；
Elastic sealing gasket setting is over an annular region and the inner ring of elastic sealing gasket is arranged two and matches with spray cistern Adjust tabletting；
Corresponding spray nozzle sheet mainstream hole and spray nozzle sheet is arranged in the mainstream hole and effluent hole corresponded on spray nozzle sheet in spray core Effluent hole；
The central axis of pressure cap is set gradually along pressure cap length direction stores discharge orifice and taper flowing hole, and storage discharge orifice, which is located at, to be leaned on Nearly jet pipe side, it is medical liquid spraying outflux that taper flowing hole, which is located at close to the small end of spray nozzle sheet side and taper flowing hole,.
Improvement to technical solution of the present invention, the effluent hole number on bottom plate is two, and two effluent holes are about mainstream hole It is symmetrical arranged or two effluent holes is arranged with mainstream hole isosceles triangle.
The bellmouth on sprinkler cap in technical solution of the present invention can be upward when nozzle cover is tightened, and causes elasticity close Packing up-regulation seamless piece inwardly squeezes upwards, realizes that side orifice discharge reduces, changes so as to cause main orifice discharge；Unclamp nozzle When cover, elastic sealing gasket restores, and side orifice discharge increases；To also make the self-excitation fog spray head internal pressure that liquidates increase or decrease, It realizes that variable is adjusted to a certain extent, changes liquid self-excitation and liquidate injection stream speed and particle size uniformity is caused to change.
Two adjustment tablettings of the inner ring setting of the elastic sealing gasket in technical solution of the present invention, adjustment tabletting is in sprinkler cap The effect of tightening is lower to be moved inward to block the spray cistern in spraying cone, to change the flow of liquid outflow side discharge orifice, into And change main orifice discharge, change outwardly or inwardly by adjusting nozzle cover (tighten or loosen).
Improvement to technical solution of the present invention, is arranged alignment pin between spray core and spray nozzle sheet.It is corresponding in spray core and spray nozzle sheet Setting contraposition pin hole, contraposition pin hole realize spray core and spray nozzle sheet installation accuracy and job requirements by alignment pin.
