Beneficial effects of the present invention:
1, by the way that solid sodium hypochlorite and active carbon and modification are added in the wettable powder preparation process of imidacloprid
Adsorbent made of SiO2, so that prepared wettable powder can not only kill the function of sucking pest, moreover it is possible to
Spider and red worm on crops are killed using dissolved sodium hypochlorite, improves the insecticidal effect of wettable powder, desinsection
Range increases, and reduces the use of other pesticides, reduces the use type of pesticide.The number sprayed insecticide is reduced, reality is improved
Efficiency in work.And sodium hypochlorite has extremely strong penetrating power, can penetrate into cell wall, virus coat, make mycoprotein
It is denaturalized lethal.It can form ecological oxygen when decomposing, and make bacterioprotein oxidative deformation rapidly, chlorine can be done directly on thallus egg
It is white, so that its denaturation is lost vigor, there is good bactericidal and Insecticidal effect.
Adsorbent is blended in the specific surface area that pulvis is increased in pulvis, improves the adsorption capacity of pulvis, can increase interior
The absorption of portion's drug.The storage capacity of drug is increased, the internal porous of adsorbent stores drug.It is sprayed at crops
Behind outside, adsorbent is attached on the blade face of crops, and residence time is longer.The antisporadics that the time can be grown are killed
Worm improves the ability of effective drug.Using modified SiO2, increases its hydrophilic ability, drug is facilitated to mix sprinkling with water.
2, grinding preparation is carried out to wettable powder using grinding device, is ground so that various materials pass through after mixing
Mill apparatus can mix more uniform, grinding more sufficiently.The height of pressing plate be free to adjust, and different rulers are ground
Very little material adapts to different work requirements.The position-limiting cover of bottom can limit the whereabouts of material simultaneously, and material size is excessive cannot
It passes through between position-limiting cover and bearing plate, is constantly ground between pressing plate and bearing plate, until being ground thoroughly, avoided not
The material for meeting size falls into bottom, improves the efficiency of work.
Material after grinding is standard compliant to fall into bottom storage, non-compliant material after the filtering of filter screen
The inside for bringing body feed tank into can be rotated by helical axis, and quilt between pressing plate and bearing plate can be flowed back into from bottom by blowing for blower
Again grinding, until the size of grinding complies with standard.The regrinding that can be automated, working efficiency is higher, and grinding is more
Add sufficiently.Helical axis rotates on strainer simultaneously, can accelerate the speed that material passes through strainer, and material is not easy to accumulate on strainer,
Strainer is not easy to plug.

Beneficial effects of the present invention: by the wettable powder preparation process of imidacloprid be added solid sodium hypochlorite with
And adsorbent made of active carbon and modified SiO2, so that prepared wettable powder can not only kill sucking mouth parts evil
The function of worm, moreover it is possible to kill spider and red worm on crops using dissolved sodium hypochlorite, improve killing for wettable powder
The range of worm effect, desinsection increases, and reduces the use of other pesticides, reduces the use type of pesticide.Reduce time sprayed insecticide
Number, improves the efficiency in real work.And sodium hypochlorite has extremely strong penetrating power, and it is outer can to penetrate into cell wall, virus
Shell keeps mycoprotein denaturation lethal.It can form ecological oxygen when decomposing, and make bacterioprotein oxidative deformation rapidly, chlorine can be direct
Mycoprotein is acted on, its denaturation is made to lose vigor, there is good bactericidal and Insecticidal effect.
Adsorbent is blended in the specific surface area that pulvis is increased in pulvis, improves the adsorption capacity of pulvis, can increase interior
The absorption of portion's drug.The storage capacity of drug is increased, the internal porous of adsorbent stores drug.It is sprayed at crops
Behind outside, adsorbent is attached on the blade face of crops, and residence time is longer.The antisporadics that the time can be grown are killed
Worm improves the ability of effective drug.Using modified SiO2, increases its hydrophilic ability, drug is facilitated to mix sprinkling with water.
Grinding preparation is carried out to wettable powder using grinding device, so that various materials pass through grinding after mixing
Device can mix more uniform, grinding more sufficiently.The height of pressing plate 16 be free to adjust, and different rulers are ground
Very little material adapts to different work requirements.The position-limiting cover 21 of bottom can limit the whereabouts of material simultaneously, and material size is crossed very much not
It can pass through between position-limiting cover and 21 bearing plates 18, constantly be ground between pressing plate 16 and bearing plate 18, until being ground thorough
Bottom avoids and does not meet the material of size and fall into bottom, improves the efficiency of work.
Material after grinding is standard compliant to fall into bottom storage, non-compliant object after the filtering of filter screen 25
Material can be rotated the inside for bringing body feed tank 23 by helical axis 11, can flow back into pressing plate 16 from bottom by blowing for blower 9 and hold
By grinding again between weight plate 18, until the size of grinding complies with standard.The regrinding that can be automated, working efficiency is more
Height, grinding more sufficiently.Helical axis 11 rotates on strainer 25 simultaneously, can accelerate the speed that material passes through strainer 25, material
It is not easy to accumulate on strainer 25, strainer 25 is not easy to plug.
