Description

Technical Field

[0001] The present application relates to the technical field of heavy metal detection devices, and in particular to a device for detecting heavy metal residues in meat. Background Art

[0002] Heavy metal pollution has long been one of the main reasons affecting China's food quality and safety. Heavy metals can accumulate in the human body. When reaching a certain threshold, they begin to destroy various biochemical reactions in the human body and cause diseases. Heavy metal pollution in meat is a serious hazard to health, especially long-term intake of excessive meat. Therefore, heavy metal testing in meat is an important part of ensuring food safety. It mainly tests harmful heavy metals such as lead, cadmium, mercury, and arsenic to ensure that the meat consumed meets the food standards.

[0003] Among them, a heavy metal detection device is needed to sample and detect meat blocks, such as a heavy metal residue detection device in meat with publication number CN111397992A, which includes an upper connecting plate, supporting legs and a lower bottom plate. The four corners of the upper end surface of the lower bottom plate are fixedly connected with supporting legs, and the supporting legs are fixed at the four corners of the lower end surface of the upper connecting plate. A support plate 1 is provided on the upper end surface of the lower bottom plate, and a detector is fixedly connected to the upper end surface of the support plate 1. A grinding barrel is embedded and fixed on the lower end surface of the upper connecting plate, and a grinding wheel is provided inside the grinding barrel. Compared with the prior art, the above-mentioned prior art has the following beneficial effects: the grinding barrel and the grinding wheel are used to grind and crush the meat blocks, the crushing efficiency is high, the digestion speed is fast, and it is convenient to support and lift the detection cup through the support plate 2, thereby improving the receiving efficiency of the minced meat and avoiding the minced meat from spilling, and it is convenient to take and put the detector and adjust the height, which is convenient for detection, viewing, and good use effect.

[0004] However, the above-mentioned prior art still has some defects in the detection of heavy metal residues in meat: 1. The above-mentioned prior art uses a grinding cylinder and a grinding wheel to grind and crush meat blocks, with high crushing efficiency and fast digestion speed, so that the detector can detect it. However, in the actual detection process, if the surface of the meat block is contaminated by the external environment before detection, it will affect the detection result of the entire meat block, which is defective.

A cutting blade 55 is arranged at the lower end of the pressing cutting plate 54. When the mounting plate 53 is pressed down, the pressing cutting plate 54 causes the cutting blade 55 to cut the meat sample in the connecting tube 42, so that the surface part and the deep part of the meat sample are separated.

[0048] After the meat sample is sucked into the connecting tube 42, the mounting plate 53 is pressed down, and the cutting blade 55 cuts the meat sample in the connecting tube 42 to separate the surface part from the deep part of the meat sample, and then under the action of the spring telescopic rod 52, the mounting plate 53 moves upward and resets.

When the mounting plate 53 is moved downward, the transmission rod 76 moves downward to trigger the control valve 75, so that the control valve 75 is opened, thereby allowing the reaction liquid to drip into the holding tank 653.

[0054] The mounting plate 53 is moved downward, and the meat sample is cut and falls into the holding tank 653. At the same time, the transmission rod 76 moves downward to trigger the control valve 75, so that the control valve 75 is opened, and then the reaction liquid drips into the holding tank 653 through the drug delivery tube 73 and the drug delivery dripper 74, so as to digest the meat sample in the holding tank 653 and precipitate and enrich the residual heavy metals. Then, the holding plate 652 is rotated to move it to the bottom of the electrochemical sensor of the heavy metal detector 18 to detect its heavy metal content.
