Description

Technical Field

[0001] This utility model relates to the field of agricultural product inspection technology, and in particular to a device for detecting toxins and pesticide residues in agricultural products. Background Technology

[0002] Toxins in agricultural products refer to naturally occurring harmful substances produced by the crops themselves, while pesticide residues are trace components of pesticides used to control pests and diseases that remain on the crops. Excessive intake can harm human health and must be controlled through standardized planting and testing.

[0003] Toxin and pesticide residue detection devices for agricultural products are crucial for ensuring food safety. Natural toxins and excessive pesticide residues can harm human health, causing poisoning and chronic diseases. Detection devices can quickly identify substances exceeding the standard, strictly preventing substandard products from entering the market. This not only protects consumer health but also regulates agricultural production, promotes green planting, and provides regulatory authorities with a basis for law enforcement, thus maintaining the safety of the food supply chain.

[0004] In agricultural product safety testing, agricultural products may produce toxins and pesticide residues due to pesticide application and metabolism during the planting process. Failure to test them in a timely manner will affect food safety. In existing technologies, spectral detection is used to identify and detect specific components by observing the reaction of light of a specific wavelength with harmful substances, thereby determining the content of toxins and pesticide residues. However, in actual use, spectral detection is affected by environmental factors. If there are stains on the surface of the detector, it will hinder the reception of light, causing the detection signal to be distorted, reducing the detection accuracy, and failing to effectively guarantee the accuracy of the detection results.

Specifically, when the testing institution 3 is working, the fixing plate 31 provides the installation base. The sample is transported into the sample cell 2 by the infusion pump 471. The light source 371 of the light source assembly 37 emits light, which is filtered by the filter 372 sliding inside the fixing plate 31 and then shines on the sample in the sample cell 2. Through the cooperation of the light source 371 and the filter 372, the output of light of a specific wavelength is achieved. The glass plate 33 at the bottom of the fixing plate 31 allows the light to pass through evenly and act on the sample. The light reflected and transmitted by the sample is received by the detector 32 on the top left side of the fixing plate 31. The detector 32 converts the light signal into an electrical signal and transmits it to the display assembly 36.

[0020] Reference Figure 2 , Figure 3 and Figure 4 The processing mechanism 4 includes a grinding base 41, the bottom of which is fixedly connected to the top left side of the workbench 1. A rotor 42 is rotatably connected to the top of the grinding base 41. A protective shell 43 is fixedly connected to the top of the grinding base 41. A centrifuge cylinder 44 is fixedly connected to the top left side of the workbench 1. A cylinder cover 45 is fixedly connected to the top of the centrifuge cylinder 44. A centrifuge assembly 46 is provided inside the centrifuge cylinder 44. The centrifuge assembly 46 includes a mesh cylinder 461, the bottom of which is rotatably connected to the bottom inside the centrifuge cylinder 44. A valve 462 is fixedly connected to the bottom right side of the centrifuge cylinder 44. A transmission assembly 47 is provided on the right side of the centrifuge assembly 46. The transmission assembly 47 includes an infusion pump 471, the left side of which is fixedly connected to the right side of the valve 462. A transmission pipe 472 is fixedly connected to the right side of the infusion pump 471. Specifically, when the processing mechanism 4 is working, the crop to be processed is placed on top of the grinding seat 41, and the rotor 42 rotates on top of the grinding seat 41 to grind the material. The protective shell 43 covers the top of the grinding seat 41. Through the cooperation between the protective shell 43 and the grinding seat 41, the material is prevented from splashing during the grinding process. The ground material is transferred into the centrifuge cylinder 44, and the cylinder cover 45 is closed on the top of the centrifuge cylinder 44. The screen cylinder 461 of the centrifuge component 46 rotates at the bottom inside the centrifuge cylinder 44. The rotation of the screen cylinder 461 generates centrifugal force to separate the material, so that the liquid in the material seeps into the bottom of the centrifuge cylinder 44 through the screen cylinder 461, while the solid remains in the screen cylinder 461. After separation, open valve 462 at the bottom right side of centrifuge cylinder 44. The liquid at the bottom of centrifuge cylinder 44 flows into the infusion pump 471 of the transfer assembly 47. The infusion pump 471 starts and delivers the liquid to sample cell 2 through transfer pipe 472. The directional transfer of the separated liquid is achieved through the cooperation of valve 462 and infusion pump 471. When it is necessary to remove solid material, open cylinder cover 45 and take out the separated solid directly from the mesh cylinder 461. The cooperation between mesh cylinder 461 and centrifuge cylinder 44 facilitates the collection of solid material. The grinding of materials is completed by the cooperation of rotor 42 and grinding base 41. Solid-liquid separation of materials is achieved by the cooperation of mesh cylinder 461 and centrifuge cylinder 44. Liquid is transferred by the cooperation of infusion pump 471 and transmission pipe 472. Safety of the processing is ensured by the cooperation of protective shell 43 and cylinder cover 45.

[0021] Working principle: Place the agricultural product to be tested on the top of the grinding seat 41 of the processing mechanism 4, cover it with the protective shell 43, start the rotor 42 to make it rotate on the top of the grinding seat 41 to grind the agricultural product. The protective shell 43 can prevent the material from splashing during the grinding process. After grinding, open the protective shell 43 and transfer the ground material to the mesh cylinder 461 inside the centrifuge cylinder 44. Close the cylinder cover 45, start the mesh cylinder 461 to make it rotate at the bottom inside the centrifuge cylinder 44. Use the centrifugal force generated by the rotation to separate the solid and liquid of the material. The liquid seeps into the bottom of the centrifuge cylinder 44 through the mesh cylinder 461, while the solid remains in the mesh cylinder 461. Next, open the valve 462 at the bottom right side of the centrifuge tube 44, start the infusion pump 471 of the transfer assembly 47, and the liquid at the bottom of the centrifuge tube 44 enters the infusion pump 471 through the valve 462, and is then transported to the sample cell 2 through the transfer tube 472. Then, start the inspection mechanism 3, and the light source 371 of the light source assembly 37 emits light. After the light is filtered by the filter 372 sliding inside the fixed plate 31, it shines on the sample in the sample cell 2 through the glass plate 33 at the bottom of the fixed plate 31. The light reflected and transmitted by the sample is received by the detector 32 on the top left side of the fixed plate 31. The detector 32 converts the light signal into an electrical signal and transmits it to the display assembly 36. The display screen 361 displays the detection data, and the detection parameters can be adjusted by the operation button 362 on the top. After the test is completed, if it is necessary to clean the sample pool 2, start the water pump 35 on the top right side of the workbench 1. The water pump 35 delivers the cleaning solution to the spray bar 34 on the front side of the fixed plate 31. The spray bar 34 sprays the cleaning solution into the sample pool 2. At the same time, start the air pump 382 of the air blowing assembly 38. The airflow generated by the air pump 382 blows the air through the air outlet bar 381 to the inside of the sample pool 2, realizing the rinsing and drying of the sample pool 2. The waste liquid after cleaning is discharged into the waste liquid tank 392 through the drain valve 391 of the recovery assembly 39 on the bottom right side of the sample pool 2. Through the above steps, the detection of toxins and pesticide residues in agricultural products is finally completed.
