Description

Technical Field

[0001] This utility model relates to the field of pesticide detection technology, specifically a rapid pesticide residue detection and sampling device. Background Technology

[0002] In agricultural production, weeding and pest control are often necessary to ensure crop growth. However, excessive application of pesticides for these purposes can lead to pesticide residues in many crops. These residues cannot be eliminated and may unknowingly be sold on the market, resulting in food poisoning from consuming these pesticide-contaminated crops. A search reveals that Chinese patent publication number CN207248551U discloses a rapid pesticide residue detection and sampling device, including a handle, a pull ring, and a blade. A support is installed below the handle, and a connector is connected to the bottom of the cutter housing. The blade surface is equipped with a cutting plate. The rapid pesticide residue detection sampling device features threaded structures on both the inner surface of the support fixing cover and the upper surface of the cutter housing. The inner diameter of the support fixing cover is equal to the outer diameter of the cutter housing, resulting in better sealing between the support fixing cover and the cutter housing and greater accuracy during detection. The cutting plate is ring-shaped, preventing it from falling into the collector. The blades are evenly distributed inside the cutting plate with their cutting edges facing upwards, facilitating the shredding of the sample to be tested. This minimizes the cutting and detection steps and human factors, increasing the accuracy of the detection.

[0003] While the above-mentioned technical solution can achieve rapid sampling and testing, it lacks a stirring function when the crushed analyte is mixed with the test reagent, resulting in insufficient mixing of the analyte and the test reagent and inaccurate test results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rapid pesticide residue detection sampling device, which has advantages such as good mixing effect of analytes and reagents, thus solving the problem of poor mixing effect of analytes and reagents.

[0005] This invention relates to a rapid pesticide residue detection and sampling device, comprising a reaction chamber. A crushing assembly is located on the left side of the top of the reaction chamber, a detection assembly is located on the right side of the inner cavity of the reaction chamber, a filter screen is located on the right side of the inner cavity of the reaction chamber, and a stirring assembly is located on the left side of the inner cavity of the reaction chamber. The stirring assembly includes a motor, which is located on the left side of the reaction chamber. A rotating rod is located at the output end of the motor, extending through and into the inner cavity of the reaction chamber on its right side. Stirring blades are provided on the surface of the rotating rod. In this invention, the analyte and detection reagent are first poured into the crushing assembly. The detection reagent is transferred to the reaction chamber through the crushing assembly, and the analyte is crushed by the crushing assembly. The sample is then transferred to the reaction chamber, where the motor runs, driving a rotating rod to rotate, which in turn drives a stirring blade. The stirring blade agitates the analyte and reagent, improving their reaction efficiency. A filter isolates the analyte and reagent, preventing inconvenience during detection. After the reaction is complete, the sample can be tested using the detection component. This process avoids the problem of insufficient mixing and inaccurate test results when the analyte and reagent are mixed after being broken down.

[0006] This invention relates to a rapid pesticide residue detection and sampling device. The crushing component includes a crushing box, which is connected to the left side of the top of a reaction chamber.

A sliding sleeve is fitted inside the inner cavity of the box cover. A sliding rod is movably connected to the inner cavity of the sliding sleeve. A pressing plate is provided at the top of the sliding rod, and a pressure plate is fixedly connected to the bottom of the sliding rod. When the sample needs to be crushed, the box cover is first opened, and the sample is placed on the annular crushing blade. The box cover is then threaded onto the crushing box. The pressing plate is then pressed, causing the sliding rod to move downwards. The sliding sleeve assists in the downward movement of the sliding rod, which in turn causes the pressure plate to move downwards. The pressure plate crushes the sample on the annular crushing blade, and the crushed sample falls into the reaction chamber for further reaction.

[0007] The pesticide residue rapid detection and sampling device of this utility model has a fixed plate fixedly connected to the bottom of the surface of the crushing box, and the inner cavity of the fixed plate is fixedly connected to the reaction box by fixing bolts. The fixed plate and fixing bolts can fix the crushing box, so that the crushing box is more effective when used and avoids the crushing box shaking during use, which would lead to the instability of the internal components.

[0008] This utility model discloses a rapid pesticide residue detection and sampling device, wherein the detection component includes a connecting plate located on the right side of the top of the reaction chamber. The top of the connecting plate is provided with a handle, and the bottom of the connecting plate is fixedly connected to a concave plate. The bottom of the concave plate is movably fitted into the inner cavity of the reaction chamber, and a test paper is held in place within the inner cavity of the concave plate. When testing is required, the test paper is first held in place within the concave plate. Then, the user holds the handle and inserts the concave plate on the connecting plate into the reaction chamber. After the test paper and the test reagent in the concave plate have fully reacted, the test paper can be removed from the reaction chamber to observe and compare the results.

[0009] The present invention relates to a rapid pesticide residue detection and sampling device, wherein the surface of the handle is covered with an anti-slip sleeve, and the inner cavity of the anti-slip sleeve is fixedly connected to the handle by an adhesive.

[0012] 1. In this invention, the test substance and reagent are first poured into the crushing assembly. The reagent is then transferred to the reaction chamber via the crushing assembly. The test substance is crushed by the crushing assembly and transferred to the reaction chamber. At this time, the motor runs, driving the rotating rod to rotate, which in turn drives the stirring blades to rotate. The stirring blades stir the test substance and reagent to react, thus improving the reaction effect. The filter screen isolates the test substance and reagent, avoiding the inconvenience of detection by the testing assembly. After the reaction is complete, the test can be performed by the testing assembly. This invention avoids the situation where the crushed test substance and reagent are not stirred during the mixing and reaction, which could lead to insufficient mixing and inaccurate test results.

[0013] 2. When the test material needs to be crushed, the present invention first opens the box cover and places the test material on the annular crushing blade. At this time, the box cover is threaded onto the crushing box. Then, the press plate is pressed, which drives the slide rod to move downward. The slide rod moves downward with the help of the sliding sleeve. The slide rod drives the pressure plate to move downward. The pressure plate crushes the test material on the annular crushing blade. The crushed test material falls into the reaction chamber to wait for reaction.

[0014] The crushing box can be fixed by fixing plates and fixing bolts, which makes the crushing box more effective during use and avoids shaking during use, which would lead to instability of the internal components.

[0015] When testing is required, first insert the test paper into the concave plate, then the user holds the handle and inserts the concave plate on the connecting plate into the reaction chamber. After the test paper and test reagent in the concave plate have fully reacted, the test paper can be removed from the reaction chamber to observe and compare the results.
