Rapid detection device for pesticide residue

Abstract

The invention discloses a rapid detection device for pesticide residue. The rapid detection device comprises an insertion pipe, a pushing rod and a pushing block, wherein the pushing rod is cooperatively inserted into the insertion pipe, the pushing block is cooperatively inserted into the pushing rod, a main body of the insertion pipe is columnar cylinder-structured insertion cylinder, and columnar hole-shaped detection holes are uniformly arrayed in the wall body of the insertion cylinder from top to bottom in a left-right symmetric manner; the insertion pipe is directly inserted into fruitsand vegetables, the pushing rod and the pushing block are pressed down, a puncture cone penetrates out of the detection holes and directly penetrate into pulps of the fruits and the vegetables, a reagent in a measuring cup is in direct contact with the pulps, and after the pushing block rebounds, the tested reagent is brought back to the measuring cup, so that a testing result is directly observed, the testing process is relatively rapid, and the testing efficiency is improved; and a measuring block I penetrates out of the detection holes at different height positions from two sides of a guide column I, the puncture testing is carried out on the pulps at different depth positions under the skins of the fruits, and the pesticide residue conditions at different depth positions in the fruitsand the vegetables can be relatively accurately measured by the whole device.

Description

Technical field [0001] The invention relates to the field of high and new technology, in particular to a rapid detection device for pesticide residues. Background technique [0002] In modern agriculture, pesticides are generally sprayed on the surface of fruits and vegetables to achieve the purpose of preventing and curing diseases and pests of fruits and vegetables. The pesticides sprayed on the surfaces of fruits and vegetables will penetrate into the interior of the fruits and vegetables through their skins. During the growth of fruits and vegetables, most of the pesticides are It is diluted, but it is inevitable that there will still be residual pesticide components on the surface or inside of the fruits and vegetables. A small amount of pesticide residue does not affect human health, but once the residual pesticide exceeds a certain value, it will cause harm to the human body. Therefore, we must detect pesticide residues in fruits and vegetables after they are mature, and d...

AI Technical Summary

Problems solved by technology

[0003] 1. The test needs to cut and process the fruits and vegetables before testing. The test process is more complicated and the efficiency is low;

[0004] 2. The test results can only show whether the pesticide residues in the fruits and vegetables exceed the standard, and cannot accurately show the specific depth of the pesticide residues in the fruits and vegetables, so the measurement results are relatively rough
