Description
Technical field
The utility model relates to plant protection equipment technical field, more particularly to a kind of exterior mixing two-fluid sector mist
Spray head.
Background technique
Currently, biological pesticide is because of the advantages that its is environmental-friendly, no chemical residues, sustainable control, 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, in order to keep drug effect, not only to have sternly to medical liquid atomizing performance when being administered
Lattice requirement, and need to guarantee the quantity and activity of bacterium in pesticide, but the country there is no the application dedicated for biological pesticide at present
Machinery, biological pesticide activity when being unable to ensure application.
In each component of Agent spraying machine, spray head is the critical piece for determining pesticide atomization, and causes biological agriculture
The critical component of medicine active constituent damage.The reason is that biological pesticide flow through spray head atomization when, first is that the active somatic cell in pesticide
It collides, impact with spray head 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, and fan nozzle ball head structure is sprayed compared to circular cone mist
