Leaching oscillation device for crop pesticide residues and crop pesticide residue leaching method

Abstract

The invention discloses a leaching oscillation device for crop pesticide residues and a crop pesticide residue leaching method, and mainly relates to the field of plant protection work. The device comprises an oscillation bottle and a host, a main machine comprises a machine base, a rotating shaft is rotatably installed on the machine base, an overturning plate is fixed to the rotating shaft in acircumferential limiting mode, two rows of installation openings are formed in the overturning plate, the interiors of the installation openings are fixed to the oscillation bottles through rotating bearings, driven belt wheels are fixed to the rotating bearings, an installation shaft is rotatably connected to the overturning plate, a one-way bearing is installed on the installation shaft, the outer ring of the one-way bearing is sleeved with a driving pulley, driven bevel gears are mounted on the periphery of the outer end of the mounting shaft, a driving bevel gear is arranged at one end ofthe rotating shaft, the driven bevel gears are meshed with the driving bevel gear, and a transmission belt is wound on all the driven belt wheels and the driving belt wheel. The method has the beneficial effects that the scouring effect of the solvent on the surface of the sample is improved, the extraction effect is improved, and the adverse effect of the instability of extraction on subsequent detection data is reduced.

Description

technical field [0001] The invention relates to the field of plant protection work, in particular to an extraction vibration device for crop pesticide residues and a method for extracting crop pesticide residues. Background technique [0002] A large number of pesticides are used in modern agriculture to control the growth of diseases, insect pests and weeds during crop production. The extensive use has brought hidden dangers to the environment and food hygiene and safety, and caused many health and social problems. Therefore, the establishment of sensitive pesticide residue analysis technology is an important part of plant protection work. [0003] In the process of pesticide residue detection, the follow-up detection is generally carried out with the cooperation of mature equipment, or the standard operation of the kit, the general error is small, and the key to its accuracy lies in the sample pretreatment. That is to maximize the extraction of pesticide residue samples i...

Problems solved by technology

[0007] The commonly used devices for extraction now include oscillators. The existing oscillators are not effective in shaking and stirring the solution. They can only form the circumferential rotation of the solution in the bottle, or mix them up and down. The former’s mixing effect in depth Not good, and the latter is a natural flip, the contact between the solvent and the sample is very uneven, resulting in a random and unstable extraction effect, which affects the accuracy of the test
