Description
Technical field
The utility model relates to soup soup under simple and easy measuring apparatus, particularly atomize that the plant surface hold-up changes and belongs to the technique in using agriculture chemical field in the simple and easy measuring apparatus that the plant surface hold-up changes.
Background technology
In order to prevent and treat the harmful organism that harms the crops, often to use agricultural chemicals in the farmland.Modal method was to carry out the agricultural chemicals field spray with different sprayers during China's agricultural chemicals used.The pesticide solution of different physicochemical properties is different in the retentivity of different plant surfaces.Owing to do not know the retentivity of each kind of plant to different pesticide solutions, often can see that a large amount of the loss caused waste on the one hand because the amount of liquid medicine of spraying has exceeded the maximum retentivity on target plant surface, also polluted environment simultaneously.Therefore need understand the retentivity of different pesticide solutions, thereby be control field soup consumption, or provide foundation by the retentivity of physicochemical property raising soup that changes soup on the target plant surface on the target plant surface.
Existing method is generally, and plant leaf blade directly is immersed in the soup, measures the soup hold-up of unit area blade under the static state after weighing, but this is different with the blade soup hold-up under when spraying dynamical state.Blade directly being immersed to belong in the soup soak, is the process that solid-liquid interface replaces solid-air interface, and droplet drops on and wettingly on the blade then belongs to adhesional wetting during spraying, is the process that liquid-gas interface and solid-air interface become solid-liquid interface.Secondly, the soup that is used for spraying, the overwhelming majority contains surfactant, and surfactant has the characteristic in Interfacial Adsorption.During spraying, soup forms a large amount of tiny droplets, new liquid-gas interface expands rapidly, surfactant molecule on the liquid-gas interface is by Macrodilution, the surface tension of soup rises, the surfactant molecule of soup inside is transferred to new liquid-gas interface then needs the time, droplet drops on the blade face and then finishes in moment, therefore tend to because droplet to be connected on the surface tension of touching blade moment excessive and can not be at the adhesional wetting spread of blade surface, therefore thereby influenced the hold-up of soup, measured the actual conditions that blade soup hold-up under the atomize more can reflect the field at blade surface.If directly immerse blade in the soup, surfactant in the soup is easier of new interfacial migration, the easier blade that makes is wetting, thereby soup is bigger in the hold-up of blade surface, can not reflect correctly that soup under the field condition is in the retentivity on target plant surface.
The utility model content
The utility model purpose is to adopt different spray techniques for research to spray the retentivity of the pesticide solution of different physicochemical properties at the target plant blade surface, provides a kind of pesticide solution of field actual conditions that approaches in the loss point of target plant blade surface and the measuring apparatus of the maximum stable hold-up on the unit area blade.
In order to solve above technical matters, the spray liquor that the utility model provides is in the measuring apparatus of plant leaf blade surface detention quantitative changeization, it is characterized in that comprising: cloche, electronic balance, carry the leaf platform, carry leaf platform support bar, carry leaf platform base, tubaeform sleeve pipe, described electronic balance places cloche inside, carrying leaf platform base is placed on the electronic balance, described cloche top offers aperture, described year leaf platform support bar passes this aperture and inserts and carry a leaf platform base and supported, carry the leaf platform and be fixed in the top of carrying leaf platform support bar, described flaring pipe cover is buckled on the cloche upper surface and is enclosed within and carries outside the leaf platform support bar, its inwall and a year leaf platform support bar loose fit.
Cloche one side is provided with glass and moves door, and the chute that this glass moves door is embedded in the cloche, is used for fixing glass and moves door and make things convenient for glass to move moving of door.The leaf platform was 0 °～90 ° angle with a year leaf platform support bar in described year.Carry the leaf platform and can become 0 °～90 ° any angles in the scope, thereby simulate the target plant blade that becomes different angles with ground, carry leaf platform support bar and can be connected by the sleeve pipe that carries on the leaf platform base with year leaf platform base with ground.
Electronic balance is put into cloche, make the aperture of the pallet aligning cloche top of electronic balance.Put into the pallet of electronic balance with carrying leaf platform base.With tubaeform casing shroud on the aperture above the cloche.With double faced adhesive tape the blade of target plant is sticked on and to carry a Ye Taishang, the aperture by tubaeform sleeve pipe and cloche top inserts in the sleeve pipe that carries on the leaf platform base, carries the mouth of pipe that the leaf platform has blocked tubaeform sleeve pipe upper end.Energized, open balance, close glass and move door, just can aim at the blade that carries on the leaf platform sprays, along with the variation of reading on the balance shows the increase of soup hold-up on blade, when reaching a maximal value, the reading of balance just begins to descend, and maximal value is the loss point of soup on this target plant blade, reading continues to descend and finally reach stable then, and the reading when stablizing is the maximum stable hold-up of blade to soup.
Further, this spray liquor is provided with circular protrusion around the aperture at described cloche top in the measuring apparatus of plant leaf blade surface detention quantitative changeization, flows in the cloche from aperture in order to prevent soup.
For the ease of regulating described year leaf platform and carrying angle between the leaf platform support bar, further, the utility model measuring apparatus also is provided with an angle adjusting mechanism.Make and carry leaf platform and the angle that carries leaf platform support bar and regulate and be fixed as 0 °～90 ° arbitrarily angled
During spraying, shower nozzle is from carrying a leaf platform 30cm～50cm, the too near atomization quality that can influence soup, and the time impulse force of spraying can influence reading.The stopping of soup reason aperture circular protrusion on every side that is sprayed on the cloche top can not flow in the interior balance on goods and services of cloche, because of tubaeform sleeve pipe with carry the block effect of leaf platform to the tubaeform sleeve pipe upper end mouth of pipe, droplet can not be sprayed onto and connect on the tube wall that carries the leaf platform and influence balance reading.
Adopt the utility model measuring apparatus to measure in plant leaf blade surface detention quantitative changeization spray liquor, test findings reflects truly in the farmland operation that soup is in the lip-deep delay situation of plant leaf blade under the atomize.For the method that directly is immersed in the soup, utilize the utility model device that soup is carried out the hold-up test, its simulation process conforms to actual, and analog result is genuine and believable.
The utility model ingenious conception, simple in structure, easy to use, effective.Be well received in the field of business, have good market outlook.
