Description
Technical field
The invention belongs to technical field of plant protection machinery, it is related to a kind of compound device for administration of drugs for being suitable to canopy density crop high and side
Method, the medicine such as the prevention and control of plant diseases, pest control being particularly suited for when cotton, seeding corn and other crops middle and later periods form canopy density canopy high or defoliant
Agent is sprayed.
Technical background
The field crops prevention and control of plant diseases, pest control all uses common spray rod type spray pattern mostly.Spray rod type spray pattern is to crop
The prevention and control of plant diseases, pest control of Seedling Stage is more effective.But modern agriculture requirement rational close planting is to improve yield, but dense planting plant growth is arrived
Middle and later periods, form canopy density canopy high.
When crop grows into the middle and later periods forms canopy density canopy high, if still using single spray bar type spraying machine tool,
Due to being stopped by dense canopy, droplet cloud is intercepted and captured by dense top layer blade first, and the droplet not being trapped continues inside
Penetrate, but the droplet amount not being trapped is successively decreased, and plant superficial deposit rate is far below in plant internal layer deposition, and " droplet sinks for appearance
Product decay " phenomenon.
The appearance of " mist droplet deposition decay " phenomenon causes only a small amount of liquid to deposit to canopy lower target to put on, and
And the excessive fluid loss of canopy layer deposition influences the prevention and control of plant diseases, pest control effect of crop in soil, reduces the effective of agricultural chemicals
Utilization rate, pollution of ecological environment.Increase formulation rate and deteriorate mist droplet deposition harmony on plant branches and leaves on the contrary.Canopy density canopy high is applied
Medicine has turned into the bottleneck problem in chemical prevention.
Suspension time is long in the air for atomizing droplet, is easily captured by target organismses, with good penetration performance, but is easy to
Drift is produced by nature wind action.Air assisted spray mode be can secondary-atomizing, reduce fogdrop diameter distribution, and energy
Change local canopy porosity by forcing air-flow, form vent flow path, by carrying droplet secretly, easily form heavy inside crop
Product.For in the dispenser of canopy density canopy crop high, air assisted spray mode can " mist droplet deposition declines in reduction to a certain extent
Subtract " phenomenon.But air assisted spray prevents floaing and changing plant part branches and leaves porosity, it is necessary to blower fan is formed to realize droplet
Very big blast, air quantity and wind speed, therefore blower fan forms the power consumption of maximum in air assisted spray.
Therefore, for canopy density canopy crop pattern feature high, in the urgent need to a kind of power consumption of invention is smaller and can press down
The comprehensive prevention and control of plant diseases, pest control device for administration of drugs of " mist droplet deposition decay " problem of system, makes that liquid droplet deposition uniformity is good, agricultural chemicals has
Utilization rate is high has important practical significance for effect.
Found through being retrieved to prior art literature, Chinese invention patent " self-propelled pesticide spraying machine suspender spraying device ", application
Numbers 201110167637.6, there is provided a kind of self-propelled pesticide applicator suspension rod sprayer unit, by sprayer unit bracket institution and
Shower nozzle is respectively arranged on suspension rod to realize preventing and treating the pest and disease damage at each position in long-stalked crops the middle and late growth stage upper, middle and lower.
But the patent due to do not apply air-flow aid in administration, therefore its dispenser droplet above crop canopies the anti-poor-performing that floats；Make
The diffusion of Wu Zhong lower floors dispenser droplet is poor.And because the shower nozzle arranged on bracket institution and suspension rod uses same mist
Drop diameter distribution, thus its it is anti-float performance and penetration performance can not be unified, so as to be difficult to optimal deposition properties.
The content of the invention
