Description
Technical field
The utility model is related to the devices that a kind of screw rod pushes the hidden pest of Conductivity detection grain grain.
Background technology
The case where pest infects in detection grain is the basic demand that pest control avoids loss, and grain storage pest largely has
There are 4 adult, ovum, larva and pupa worm states, wherein Main Stored Grain Insects are mostly that ovum, larva and pupa are hidden in the generation of grain intragranular portion.
The detection of pest is subject to and samples screening examination adult and a small number of larvas in grain in China's specification at present, generally do not include for
The detection of hidden pest in grain grain, the especially detection to grain storage primary pest rice weevil, sitophilus zea-mais, gelechiid larva etc..In grain
Hidden pest is not easy to detect, but its harm is very serious, and can usually miss effectively preventing opportunity etc..In the world for grain grain
In hidden pest detection method include x-ray method, it is dioxy carbon gas detection method, long-term cultivation observation, decoration method, enzyme-linked
Immunization, Near-Infrared Absorption Method etc., it is the most accurate with x-ray method in these methods, but its equipment price is expensive and operation is loaded down with trivial details,
Other methods also more to be limited to apply under laboratory condition.In production practices, grain circulation speed is fast, quantity is big, needs quick side
Just detection grain intragranular portion pest infection conditions, to determine trade decision, control measure etc..It is hidden to squeeze the broken method detection grain grain of wave
The method of pest is expected to adapt to largely, quickly, easily to detect the hidden pest in grain grain.U.S. Pearson and Brabec
(2007) have developed and the device of its conductance difference detected with two-wheeled relative rolling crushing grain grain, can in grain grain big larva and
Pupa detects.But it in the presence of medium-sized and large-scale larva and the pupa that can only be detected in grain, device volume is big and weighs, and is not easy to live carrying
And operation, can deviate because of between centers when two idler wheel opposing compression numbers are excessive influences its precision, electric signal and the grain grain conductance of foundation
Relationship deviates.More importantly its price is still up to 15600 dollars（The every price currently recognized）, this city of China still
It is not easily accepted by.
