[0002] The development of agricultural industrialization makes the production of agricultural products more and more dependent on exogenous substances such as pesticides, antibiotics and hormones. The use of pesticides in China's agricultural products remains high, and the unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer food safety, and in severe cases, causing consumers to become ill, develop abnormally, and even directly leading to poisoning and death. There are many types of rapid detection methods for pesticide residues, which can be mainly divided into two categories according to their principles: biochemical determination method and chromatographic detection method.

[0011] Preferably, the mixing frame is rotatably connected to the extraction box, and the mixing frame is connected to the extraction box by bolts and threads.

[0012] The beneficial effects of this utility model are:

[0013] 1. The rotating frame is equipped with grinding chambers on all four sides. The rotating frame and water spray cleaning system allow for simultaneous sample grinding and cleaning of the grinding chambers. Grinding chambers are located on all four sides of the top of the rotating frame. After the sample is chopped, it is poured into the grinding chambers on the left and right sides. Motors A and B work together to grind the sample. During grinding, the valve on the feed pipe opens, and the ground sample falls into the extraction chamber below. After the sample is removed, the valve on the feed pipe closes, and the chemical pump above the rotating frame starts, drawing extractant from the chemical tank and conveying it into the grinding chamber. Motor A rotates, causing the extractant to rotate, and simultaneously rotating the remaining sample with the extractant. After a certain period of rotation, the valve on the feed pipe opens, and the remaining sample in the grinding chamber falls into the extraction chamber with the extractant. The chemical pump then draws the extractant into the grinding chamber. After the sample falls into the extraction chamber and an appropriate amount of extractant is delivered, the pump is turned off, the valve on the feed pipe is closed, and the motor d inside the base rotates, driving the connected rotating frame to rotate 90 degrees. This allows the used pulverizer to rotate 90 degrees and move above the waste liquid tank. At this time, the water spray frame is located above the pulverizer. The water pump starts to draw water from the water tank and deliver it into the water spray frame, which then delivers it into the pulverizer. The motor a rotates, causing the water to rotate inside the pulverizer, thus cleaning it. After cleaning, the valve on the feed pipe opens, and the cleaned waste liquid falls into the waste liquid tank. This allows for the cleaning of the used pulverizer. While cleaning the pulverizer, samples are placed into the pulverizer above the extraction chamber for pulverization. This allows for simultaneous cleaning and sample pulverization, resulting in high processing efficiency.

[0014] 2. After the sample is pulverized by the pulverizing blades, it is further ground by the grinding balls, resulting in complete pulverization. The chopped sample is poured into the pulverizing chamber. The motor a at the top of the pulverizing chamber rotates, driving the connected pulverizing shaft to rotate. The rotation of the pulverizing shaft drives the connected pulverizing blades to rotate. The continuous rotation of the pulverizing shaft drives the pulverizing blades to pulverize the sample in the pulverizing chamber. After pulverization, the sample falls into the grinding tank and between the grinding balls below. The motor b rotates, driving the connected rotating shaft b to rotate. The rotation of rotating shaft b continuously drives the connected grinding balls to rotate, grinding the sample between the grinding balls and the grinding tank. This process can grind the sample into smaller pieces, while further breaking down larger sample pieces, allowing them to fully contact the extraction solution for extraction.
