A motor bracket 8 is connected to one side of the stirring tank 6, and a motor 9 is connected to the top of the motor bracket 8. The output end of the motor 9 is connected to... A pulverizing rod 10 is provided, with one end of the pulverizing rod 10 extending into the interior of the mixing tank 6. Multiple sets of pulverizing blades 11 are connected to the surface of the pulverizing rod 10. An arc-shaped top cover 12 is hinged to the top of the mixing tank 6. A lifting handle 13 is connected to one side of the top of the arc-shaped top cover 12. An extraction liquid drain pipe 14 is connected to the bottom of the mixing tank 6. Two mounting bases 15 are connected to the top of the workbench 1 below the extraction liquid drain pipe 14. A shelf 16 is slidably arranged between the two mounting bases 15. A detection slot 17 is opened at the top of the shelf 16. A transparent scale plate 23 is connected to the front of the storage tank 2.
[0021] A through groove 18 is provided on one side of the shelf 16, and the through groove 18 is connected to the detection card slot 17. A pull handle 19 is provided on one side of the shelf 16 below the through groove 18. Its function is to facilitate the removal of the detected card through the through groove 18, thereby making it convenient to replace the new detection card and improve the detection efficiency.
[0022] A heating lamp holder 20 is connected between the two mounting bases 15 and located below the shelf 16. A heating lamp 21 is connected inside the heating lamp holder 20. A heating component 22 is connected to one side of the liquid storage tank 2, and the heating component 22 is electrically connected to the heating lamp 21. Its function is to provide electrical energy to the heating lamp 21 through the heating component 22. The heating lamp 21 emits heat to heat the test card on the shelf 16, thereby accelerating the chemical reaction on the test card, shortening the test time, and improving work efficiency.
[0023] Three pulverizing rods 10 are each connected to a pulley 24 on the outer surface of the mixing tank 6. A transmission belt 25 is fitted between the pulleys 24. The function of the transmission belt 25 is to drive the three pulleys 24 to rotate synchronously through the transmission belt 25. When one of the motors 9 is started, the other two pulleys 24 can be driven to rotate synchronously through the transmission belt 25, thereby realizing synchronous stirring of the three mixing tanks 6, improving stirring efficiency, and ensuring that the sample processing progress in different mixing tanks 6 is consistent, which facilitates subsequent unified detection and analysis.
[0024] A one-way valve 26 is connected to the surface of the extractor drain pipe 14. A filter pipe 27 is threaded onto the bottom end of the pulley 24. Two slots 28 are formed on the surface of the filter pipe 27. A filter plate 29 is slidably installed inside the filter pipe 27 through the slots 28. A pinch plate 30 is connected to the outer ring of the filter plate 29. An extraction nozzle 31 is connected to the bottom end of the filter pipe 27. Its function is to prevent the extract from flowing back into the mixing tank 6 during the discharge process through the one-way valve 26, thus avoiding contamination. At the same time, the filter plate 29 in the filter pipe 27 can filter the extract, remove impurities, improve the purity of the extract, and thus improve the accuracy of detection. When it is necessary to clean or replace the filter plate 29, it can be pulled out of the filter pipe 27 by pinching the pinch plate 30, which is simple and quick. The design of the extraction nozzle 31 can precisely control the dripping of the extract, reduce operational errors, and improve the accuracy of detection.
[0025] A support pole 32 is connected to one side of the top of the workbench 1. A control panel 33 is rotatably mounted on the surface of the support pole 32 and is electrically connected to the heating component 22. The control panel 33 allows users to easily operate the heating component 22, turning the heating lamp 21 on and off, and adjusting its heating temperature to meet different testing needs and improve the flexibility and practicality of the equipment. At the same time, the control panel 33 makes the entire testing process more intelligent and automated, reducing the tediousness and errors of manual operation.
[0026] The bottom of the workbench 1 is connected to four support legs 34, which are arranged in a rectangular shape. Their function is to improve the stability of the entire device and ensure that it will not shake or tip over due to external forces during operation, thereby ensuring the smooth progress of the testing work and the safety of the operators.
[0027] Working Principle: In operation, firstly, add an appropriate amount of organic reagent to the storage tank 2 through the water inlet 3. Then, place the food sample to be tested into each of the three mixing tanks 6 and close the arc-shaped top cover 12. Next, start the motor 9. The output of the motor 9 drives the crushing rod 10 and the crushing blades 11 on its surface to rotate at high speed, rapidly crushing and mixing the food sample. Simultaneously, water from the storage tank 2 enters the three mixing tanks 6 through the liquid conduit 7, mixing with the crushed food sample to form an extract. During the stirring process, since each of the three crushing rods 10 is externally connected to a pulley 24, and the pulleys 24 are connected by a transmission belt 25, when one motor 9 starts, it can synchronously drive the other two pulleys 24 and the corresponding crushing rods 10 to rotate, achieving synchronous stirring of the three mixing tanks 6 and improving stirring efficiency. After stirring is complete, open the one-way valve 26 on the surface of the extract drain pipe 14. The extract is discharged through the filter pipe 27 under gravity. The filter plate 29 inside the filter pipe 27 filters the extract, removing impurities. The filtered extract drips through extraction nozzle 31 onto the detection card in detection card slot 17 on the placement plate 16 for subsequent pesticide residue testing. During the testing process, the heating component 22 can be controlled via the control panel 33 to turn the heating lamp 21 on and off and adjust the heating temperature. The heating lamp 21 emits heat to heat the detection card on the placement plate 16, accelerating the chemical reaction on the detection card and shortening the testing time. After the test is completed, the placement plate 16 can be pulled out from the mounting base 15 via the pull handle 19 for easy replacement of a new detection card for the next round of testing. At the same time, the filter plate 29 can be pulled out from the filter tube 27 via the pinch plate 30 for cleaning or replacement, ensuring the continuous and stable operation of the equipment.
