Description

Technical Field

[0001] This utility model relates to the field of sample crusher technology, specifically a sample crusher for pesticide residue detection. Background Technology

[0002] In pesticide residue detection, the selection of a sample crusher is crucial because it helps to refine the sample to a suitable particle size for testing. Typically, the design of these crushers must consider not only the physical properties of the sample (such as hardness and moisture content) but also ensure that the crushed sample is not contaminated and can effectively release pesticide components from the sample, facilitating subsequent detection and analysis.

[0003] For example, a sample crusher for pesticide residue detection, as disclosed in announcement number CN221558591U, includes an installation box. A filter frame is rotatably connected inside the installation box, and multiple first crushing blades are fixedly connected to the inner surface of the filter frame. This sample crusher for pesticide residue detection uses a first motor to drive a first rotating shaft to rotate. The first rotating shaft drives a transmission tube and the first crushing blades to rotate via a first gear and a second gear. Subsequently, a second motor drives the filter frame and the first crushing blades inside the filter frame to rotate in opposite directions relative to the second crushing blades, thereby achieving thorough crushing of the raw materials. Then, by driving the filter frame to rotate, the juice in the crushed raw materials is fully ejected under centrifugal force, thereby collecting the juice in the test sample, facilitating subsequent detection of pesticide residues in the sample, and improving the accuracy of the detection.

[0004] The aforementioned patent proposes that the raw materials can be chopped and the juice of the chopped raw materials can be fully ejected under centrifugation to complete the collection of juice from the test sample. However, during the use of the sample crusher, since some drugs are heat-sensitive, the friction between the sample and the equipment during the crushing process will be converted into heat energy, which will cause the temperature to rise and the pesticide to decompose, affecting the accuracy of the test results. Utility Model Content
