Rapid pesticide residue detection instrument

Abstract

The invention discloses a pesticide residue rapid detection instrument, and relates to the technical field of detection device. The pesticide residue rapid detection instrument comprises a base; telescopic rods are fixedly connected to the four corners of the upper surface of the base, springs sleeve the outer sides of the telescopic rods, a bottom plate is fixedly connected to the top ends of thetelescopic rods, and a shell is fixedly connected to the middle of the upper surface of the bottom plate; a motor is fixedly connected to the inner wall of the rear side of the shell, a rotating shaft is fixedly connected to the output end of the motor, and a gear is fixedly connected to the end, away from the motor, of the rotating shaft. Through cooperation of the telescopic rods, the springs,the motor, the rotating shaft, the gear, the frame body and a gear rack, the bottom plate, a supporting plate, a top plate, a hydraulic cylinder, a lifting plate, a pipe plug, the base and reagent pipes can be driven to move up and down, so that the reagent pipes are driven to perform small-amplitude reciprocating swing, and a solution in the reagent pipes can be oscillated and mixed; therefore, the accuracy of subsequent detection results is ensured.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a rapid detection instrument for pesticide residues. Background technique [0002] Agriculture is an industry that produces food and industrial raw materials through the cultivation of animals and plants, and is an important pillar of the national economy. Pesticides play a significant role in promoting the development of forestry and animal husbandry, and can guarantee the growth of plants, but the hazards of pesticide residues are also very serious, which will lead to environmental pollution and threats to human health problems. Therefore, the problem of pesticide residue hazards has attracted more and more attention. In the detection of pesticides in agricultural products, the enzyme inhibition rate method is generally used, which uses the specific binding principle of cholinesterase to organophosphorus and carbamate pesticides.

Pesticides play a significant role in promoting the development of forestry and animal husbandry, and can guarantee the growth of plants, but the hazards of pesticide residues are also very serious, which will lead to environmental pollution and human health problems. Therefore, the problem of pesticide residue hazards has attracted more and more attention

In the detection of pesticides in agricultural products, the enzyme inhibition rate method is generally used, which uses the specific binding principle of cholinesterase to organophosphorus and carbamate pesticides. Generally, the same batch of agricultural products needs to be tested for multiple groups of test samples. To avoid the small number of test samples, making the test results unconvincing. In actual operation, the test personnel need to drop the cholinesterase solution into multiple reagent tubes one by one, and then manually shake them one by one to make the solvent and agricultural products sliced ​​or squeezed. The juice is fully mixed to ensure the accuracy of the test results. However, this operation makes the workload of the test personnel larger, and the oscillation time is not uniform, and there will be deviations in the test.
