Problems solved by technology
[0005] Although this application solves the problems in the background technology to a certain extent, there are the following problems in this application: 1. The amount of juice produced after the crushing of different agricultural products is different. When the juice after the crushing of agricultural products is detected, there is no quantitative Measurement; 2. In the case of not knowing the amount of agricultural product juice, the added reagent is not quantitative, and cannot be added in proportion to the amount of agricultural product juice, which will cause errors in the detection results

The invention discloses a heavy metal detection device in agricultural products and a detection method thereof, relates to the technical field of heavy metal detection, and solves the problem that different amounts of juice produced after crushing different agricultural products are different in the prior art, and when detecting the juice of crushed agricultural products , there is no quantitative measurement and when the amount of agricultural product juice is not known, the added reagent is not quantitative, and the problem that it cannot be added in proportion to the amount of agricultural product juice. A heavy metal detection device in agricultural products and a detection method thereof proposed by the present invention drive the first rack and the second rack to move up and down through the gear assembly, and control the first piston to take liquid quantitatively and the second piston to release reagents in proportion, which can realize Multiple sampling tests avoid improper proportion of reagents and improve detection accuracy; when sampling, the juice of agricultural products and reagents are first mixed in the notch of the arc-shaped plug, and then flow into the detection cylinder to improve the mixing effect of reagents and facilitate operation.
Description
technical field [0001] The invention relates to the technical field of heavy metal detection, in particular to a heavy metal detection device in agricultural products and a detection method thereof. Background technique [0002] The commonly used detection methods for heavy metals in agricultural products are mostly to extract agricultural product samples and crush them, then add detection reagents to them, and compare them with color comparison cards after the reaction is completed. The whole process requires manual operation, but specific detection reagents are corrosive or other hazards , will bring harm to inspectors. [0003] Chinese patent CN215263144U discloses a heavy metal detection equipment for agricultural products, which includes a detection table and a colorimetric turntable. It is connected with a drive motor, the bottom end of the drive motor is connected with a drive shaft in rotation, the bottom end of the drive shaft is fixedly connected with a hydraulic ...
