Food pesticide residue sampling device

Abstract

A food pesticide residue sampling device includes a housing; a basin is fixedly mounted in the housing; the top surface of the basin is open; a plurality of drain holes are formed in the bottom surface of the basin; electromagnetic valves are fixedly mounted in the drain holes; a through groove is formed in the back surface of the housing; a liquid collecting box is movably mounted in the throughgroove; the top surface of the liquid collecting box is open; the drain holes are all positioned above the liquid collecting box; the inner wall bottom surface of the basin is connected with the lowerend of a rotating shaft through a bearing; the upper end of the rotating shaft is fixedly connected with the bottom surface of a screen; the periphery of the screen is fixedly connected with the bottom of the inner wall of a pipe body; the periphery of the pipe body is fixedly connected with an inner ring of a gear ring; a motor is fixedly installed on one side of the inner wall of the basin; anoutput shaft of the motor faces downwards and is fixedly provided with a gear; the gear is engaged with the gear ring; a pressing block is arranged in the pipe body and is of a hollow structure, and the bottom face of the pressing block can make contact with the top face of the screen. According to the invention, not only can the filtering process of solvent liquid be accelerated, but also the filtered food residues can be effectively cleaned.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing, in particular to a food drug residue sampling device. Background technique [0002] During the production and cultivation of food and agricultural products, it is necessary to spray and release drugs to improve production efficiency and reduce the growth cycle. There are many drug residues in food products. The drug is sampled and checked to determine whether the drug residue exceeds the standard. In the prior art, the solvent liquid is mixed with the food sample, and then the content of the solvent liquid is detected and analyzed to determine whether the drug residue exceeds the standard. For example, the publication number CN207147803U discloses a food drug residue sampling device, which uses filtration to filter out Food residues, but food residues often adhere to a part of the solvent, people need to wait for the solvent in the food residues to filter out before taking ...

In the prior art, the solvent liquid is mixed with the food sample, and then the content of the solvent liquid is detected and analyzed to determine whether the drug residue exceeds the standard. For example, the publication number CN207147803U discloses a food drug residue sampling device, which uses filtration to filter out Food residues, but food residues often adhere to a part of the solvent, people need to wait for the solvent in the food residues to filter out before taking out the container, which takes a long time, otherwise, the solvent will not fall into the container and will drip into the device , people need to clean up the device afterwards, which is more time-consuming and laborious
