Pesticide residue quantity detection device for agricultural products

Abstract

The invention discloses a detection device for pesticide residues used in agricultural products. A heating device is arranged on a base; Unicom has a reagent adding tube and a feeding tube set at an angle; a liquid outlet pipe is provided on the lower side of the detection container, and a sealing tube is provided at the lower end of the liquid outlet pipe; a stirring shaft is provided in the detection container; a stirring blade is provided on the stirring shaft; The rotating motor is set above the detection container, and the rotating shaft of the rotating motor passes through the square groove at the upper end of the detecting container and is connected to the stirring shaft; the base is located on the side of the heating device and is also provided with a rotating shaft for driving the rotating motor to move left and right in the square groove The left and right driving mechanism of the invention can make the stirring blade move back and forth, so that the reagents and agricultural products can fully react, and at the same time, it can also be heated at the bottom of the detection container to further ensure the sufficient chemical reaction and the accuracy of detection.

Description

technical field [0001] The invention belongs to the technical field of agricultural product detection, and in particular relates to a detection device for pesticide residues used in agricultural products. Background technique [0002] Agricultural products are indispensable daily food in people's life. The quality of agricultural products is related to people's health. The existing agricultural products are often sprayed with pesticides in the production process to ensure the growth of crops. [0003] The main causes of excessive pesticide residues in crops are organophosphorus pesticides and carbamate pesticides that are banned from being used in vegetable production in some countries, such as methamidophos, omethoate, phorate, parathion, and methyl parathion etc., thereby causing harm to people. Most of the detection methods for pesticide residues use chemical rapid detection method, which is mainly based on the oxidation-reduction reaction, the hydrolyzate reacts with th...

Problems solved by technology

[0003] The main causes of excessive pesticide residues in crops are organophosphorus pesticides and carbamate pesticides that are banned from being used in vegetable production in some countries, such as methamidophos, omethoate, phorate, parathion, and methyl parathion etc., causing harm to people

Most of the detection methods for pesticide residues use chemical rapid detection method, which is mainly based on the oxidation-reduction reaction, the hydrolyzate reacts with the detection solution to change color, and is used for the rapid detection of organophosphorus pesticides. There is no special stirring structure in the machine, which leads to insufficient chemical reaction. At the same time, there is no heating device to make the chemical reaction more sufficient, which leads to inaccurate detection results and brings many problems to actual detection.
