Description
Technical field
The utility model relates to a kind of test pre-treatment extraction element.
Background technology
China uses about 1,000,000 tons of chemical pesticides every year on crop products such as vegetable and fruit.There are 99% agricultural product in process of production, all sprayed various agricultural chemicals to some extent.Particularly concerning growth period short vegetables, melon and fruit based food, because insect pest is many, the excess dispenser causes the residues of pesticides phenomenon that exceeds standard day by day to increase the weight of.In the extensive chemical pesticide that uses of China 80% organic phosphates and carbamate chemicals for agriculture for high poison arranged approximately, mainly comprise flolimat, Folithion, acephatemet and carbofuran etc.And the amount that really is used to kill the disease and pest agricultural chemicals only accounts for the 10%-20% of amount of application, and all the other most agricultural chemicals all remain in the vegetable and fruit surface, perhaps infiltrate in soil, the water and air.The expert points out, if people long-term uses agricultural product such as vegetables that residues of pesticides are arranged, melon and fruit, and very harmful to health: the organophosphorus pesticide of low dosage can make the people produce slow poisoning, is undoubted to human carcinogen, teratogenesis, mutagenic harm; Acute poisoning can cause muscle cramp, pupil contraction, expiratory dyspnea, even causes dead.In recent years, the food poisoning that is caused by the residues of pesticides on the agricultural product such as vegetables, melon and fruit takes place again and again.
GB GB/T 5009.199-2003 " organophosphorus and carbamate pesticide residue amount fast detecting in the vegetables " has stipulated two kinds of method for quickly detecting by organophosphorus and carbamate pesticide residue amount in the enzyme inhibition method mensuration vegetables.The rapid screening that is applicable to organophosphorus and carbamate pesticide residue amount in the vegetables is measured, and has been widely used in the Fast Determination of Pesticide Residue in market, supermarket, food and drink and the place of production.
Fast Determination of Pesticide Residue sample preparation conventional method: choose representational vegetable sample, rinse out surperficial earth, be cut into the square fragment in the 1cm left and right sides; Get quantity of sample, put into beaker or extraction flask, add buffer solution; Vibration 1min～2min, or vibrate 50 times, or wash 50 times.Then extract being carried out enzyme inhibition method measures.Present sample pre-treatments mode is through manually vibrating or washing, and is time-consuming, and efficient is not high, and it is very big influenced by human factor, and it is lack of standardization that a lot of situation are that operating personnel operate, and it is insufficient that vibration is extracted, thus the accuracy that influence detects.
The utility model content
The purpose of the utility model provides a kind of Fast Determination of Pesticide Residue pre-treatment extraction element, the inadequate problem that present Fast Determination of Pesticide Residue pre-treatment manual extraction is time-consuming, efficient is not high, personnel operation is lack of standardization to solve, extract.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: said device comprises support, motor, gear train, at least one promotes muscle, a plurality of roller bearing and a plurality of extraction flask; Gear train comprises driving wheel and a plurality of engaged wheel; Support is provided with a plurality of roller bearings that laterally arrange; The output shaft of motor and the driving wheel of roller bearing are in transmission connection, and on the end of other each roller bearings engaged wheel are housed, and driving wheel directly or indirectly is connected with engaged wheel; A plurality of roller bearings rotate through drive mechanism; Extraction flask is positioned on two adjacent roller bearings, and the inwall of each extraction flask is provided with at least one lifting muscle and the two processes one or bonding, and each promotes muscle and is provided with a plurality of dripping holes or groove.
The utlity model has following beneficial effect: the utility model utilizes roller bearing that the rotational power of extraction flask is provided, and extraction flask has the lifting muscle sample is promoted, and generation is beaten and rubbed; Improve extraction efficiency; Promote muscle and be provided with dripping hole or groove, when extraction flask rotates, sample is carried out drip washing; The utility model is simple in structure, easy operating, and extraction efficiency is high, extracts fully.
