Description
Technical field
The present invention relates to plant protection equipment technical field, more particularly to a kind of exterior mixing two-fluid sector mist spray
Head.
Background technology
Currently, biological pesticide because its is environmental-friendly, no chemical residues, sustainable control the advantages that, it is anti-in agricultural pest and disease damage
There is important development potentiality in controlling, be increasingly becoming research hotspot and important directions.
But biological pesticide pesticide application technology is backward, utilization rate is low has become the critical issue for limiting its development.With chemical agriculture
Medicine is different, and biological pesticide is active system, and in order to keep drug effect, medical liquid atomizing performance when not only will be to dispenser has sternly
Lattice requirement, and need to ensure the quantity and activity of bacterium in pesticide, but the country there is no the dispenser dedicated for biological pesticide at present
Machinery, biological pesticide activity when being unable to ensure dispenser.
In each component of Agent spraying machine, nozzle is to determine the critical piece of pesticide atomization, and cause biological agriculture
The critical component of medicine active constituent damage.The reason is that biological pesticide flow through nozzle atomization when, first, the active somatic cell in pesticide
It collides, impact with nozzle inner wall, second is that liquid stress, the two such as the liquid tensile stress generated when atomization and shear stress are equal
It can aggravate the active somatic cell damage in pesticide, cause the reduction of biological pesticide activity.
Existing fog spray head has cone nozzle and fan nozzle, fan nozzle ball head structure to be sprayed compared to circular cone mist
Head, although the activity injury to biological agent is larger, fan nozzle spray regime is wide, and because of its unique mist type point
Cloth has irreplaceable role when more nozzle combinations spray on large-scale spraying machine.
Therefore, one kind how is provided on the basis of meeting fan nozzle spray shapes and vapour inhalation, and can be reduced
Biological living damages in biological pesticide, ensures biological pesticide activity, fan-shaped to reach prevention and control of plant diseases, pest control purpose exterior mixing two-fluid
The problem of fog spray head is those skilled in the art's urgent need to resolve.
Invention content
In view of this, on the basis of meeting fan nozzle pulverability, to ensure biological pesticide activity, reduce to the greatest extent
Damage and destruction of the active somatic cell when flowing through nozzle in pesticide, the present invention provides a kind of sprays of exterior mixing two-fluid sector mist
Head.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of exterior mixing two-fluid fan nozzle, including：
Sprayer body, the sprayer body offer the first water inlet, sprayer body inside shape close to the position of its first end
It is connected to the accommodating chamber at having the accommodating chamber in axial direction running through the sprayer body both ends, first water inlet；
