A pesticide residue detection pretreatment device

Abstract

The invention relates to a pesticide residue detection pretreatment device, which comprises a base, a top plate, a controller, a crushing mechanism, a water supply mechanism, a beaker, a uniform shaking mechanism, two support plates and two placing mechanisms, wherein the crushing mechanism comprises a reciprocating assembly, a reciprocating plate, a flat plate, a cutting ring, two directional assemblies, a plurality of cutter blades and a plurality of first springs; the uniform shaking mechanism comprises a plurality of uniform shaking assemblies; each uniform shaking assembly comprises a vertical rod, a first motor, an eccentric wheel, a driving ring and a plurality of second springs. The pesticide residue detection pretreatment device has the advantages that through the crushing mechanism, vegetable samples are cut into fragments, so that juice liquid in the vegetable fragments can be conveniently dissolved into distilled water to form extraction liquid; in addition, the uniform shaking mechanism is used for vibrating and shaking the breaker, so that the juice liquid in the vegetable fragments can be fully dissolved into distilled water to form extraction liquid; operators can conveniently detect the extraction liquid through a pesticide residue detection card, so that the efficiency and the precision of the pesticide residue detection are improved; the practicability of equipment is improved.

Description

technical field [0001] The invention relates to the field of agricultural product production quality detection systems, in particular to a pesticide residue detection and pretreatment device. Background technique [0002] Pesticide residue refers to the phenomenon that part of the pesticide remains directly or indirectly in grains, vegetables, fruits, livestock products, aquatic products, soil and water after the application of pesticides in agricultural production. Therefore, pesticide residues have become a widely concerned issue, and people have put forward higher requirements for the detection of pesticide residues. [0003] However, at present, when people detect pesticide residues in vegetables, the pretreatment of vegetables is still done manually, which is not conducive to improving the detection efficiency, and at the same time, manual operations are prone to errors, so the use of manual operations will also affect the detection accuracy of pesticide residues.
