Problems solved by technology
[0003] In the traditional detection of pesticide residues in fruits and vegetables, when the length of fruits and vegetables is long, it is impossible to detect residual pesticides in different positions of fruits and vegetables, and it is impossible to form a comparative detection during the detection process, and the detection effect is poor. The current method to solve the problem of organophosphorus pesticide residues Chromatography is the main method. This kind of method is complicated to deal with and requires expensive instruments. It is not suitable for on-site detection. The traditional method is based on enzyme inhibition and colorimetric detection. Some vegetables are prone to errors in reagent detection. detection phenomenon, which affects the detection reliability and is not practical

Embodiment Construction
[0032] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.
[0033] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a detection device for pesticide residues in fruits and vegetables, comprising: a drug dropping mechanism 3, a groove 4, and a movable plate.
[0034] Specifically, the inside of the drug dropping mechanism 3 is provided with a plurality of drug containing chambers, and the plurality of drug containing chambers are distributed at intervals along the length direction of the drug dropping mechanism 3, and detection reagents are added in the drug containing chambers; one side of the drug dropping mechanism 3 is provided with a concave Groove 4, the clamping plate...

The invention relates to a detection device and a method for detecting residual pesticides in fruits and vegetables, comprising: a drug dropping mechanism, a groove, and a movable plate; a plurality of drug containing chambers are arranged inside the drug dropping mechanism, and the plurality of drug containing chambers are arranged along the The drug dropping mechanism is distributed at intervals in the length direction, and detection reagents are added in the drug containing chamber; a groove is arranged on one side of the drug dropping mechanism, and a slideway is arranged on the groove, and the clamping plate is movably connected to the slideway. On the road, the clamping plate can slide along the length direction of the dripping mechanism. A blade is arranged on one end surface of the clamping plate. The sliding clamping plate drives the blade to sample fruits and vegetables. The sampled samples pass through the collection port inside the blade. Send it into the sample cavity inside the card board, and drop an appropriate amount of detection reagent on the sample through the drug dropping mechanism, so as to realize the detection and analysis of pesticide residues in different positions of fruits and vegetables. It is easy to use, and the present invention also relates to the use of the detection device method.
Description
technical field [0001] The invention relates to a pesticide detection device, in particular to a detection device and a use method for residual pesticides in fruits and vegetables. Background technique [0002] Due to its strong chemical stability, pesticides are easy to remain in crops or other environments. When the residual amount reaches a certain value, they will regret being eaten and accumulate in the body, causing chronic poisoning. At present, the detection of pesticide residue pollution in my country is divided into Three types, organophosphorus pesticides, pyrethroids, and fungicides. Organophosphorus pesticides are the most widely used pesticides in my country at the present stage due to their high efficiency, safety, economy, convenience, and wide application range in the control of agricultural pests and diseases. [0003] In the traditional detection of pesticide residues in fruits and vegetables, when the length of fruits and vegetables is long, it is impossib...
