The output end of the first electric telescopic rod 3 slides through the inner surface of the fixed frame 2. A mounting plate 6 is arranged on the output end of the first electric telescopic rod 3. A first motor 7 is fixedly connected to the top of the mounting plate 6. The output end of the first motor 7 rotates and passes through the top of the mounting plate 6. The output end of the first motor 7 is fixedly connected to the connecting plate 4; a crushing assembly 8 is fixedly connected to the bottom of the connecting plate 4, and the crushing assembly 8 includes a first mounting block 801; a pressing assembly 9, and the pressing assembly 9 The pressing assembly 9 is fixedly connected to the bottom of the connecting plate 4, and includes a second mounting block 901. The top of the first mounting block 801 is equidistantly fixedly connected to a plurality of first connecting rods 803. The tops of the plurality of first connecting rods 803 are all fixedly connected to the bottom of the connecting plate 4. The top of the first mounting block 801 is fixedly connected to a second motor 802. The output end of the second motor 802 rotates through the top of the first mounting block 801. The output end of the second motor 802 is fixedly connected to a rotating rod 804. The outer surface of the rotating rod 804 is equidistantly provided with a plurality of blades 80 5. A plurality of second connecting rods 903 are equidistantly fixedly connected to the top of the second mounting block 901, and the tops of the plurality of second connecting rods 903 are all fixedly connected to the bottom of the connecting plate 4. A second electric telescopic rod 902 is arranged on the top of the second mounting block 901, and the output end of the second electric telescopic rod 902 slides through the top of the second mounting block 901, and a pressing plate 904 is arranged on the output end of the second electric telescopic rod 902. The inner surface of the fixing frame 2 is symmetrically fixedly connected with fixing rods 5, and the outer surfaces of the two fixing rods 5 are both slidably connected to the inner surface of the mounting plate 6.

[0025] The effect achieved by the entire embodiment 1 is that when testing agricultural products, the bottom plate 1 is first placed in a suitable location to provide stability, and then an appropriate amount of agricultural products of a certain size are placed in the filter cartridge 14. The filter cartridge 14 is threadedly connected to the placement block 13. The placement block 13 is limited in the base 12 by the square protrusion at the bottom thereof, which plays a fixing role. The initial reset of the device is that the crushing assembly 8 is above the filter cartridge 14. At this time, the first electric telescopic rod 3 set on the inner surface of the fixing frame 2 is started. When its output end is retracted, the mounting plate 6 will slide downward along the outer surface of the two fixing rods 5, so that the first mounting block 801 will be located between the plurality of first Under the connection between the connecting rod 803 and the mounting plate 6, its bottom will contact the top of the filter cartridge 14, and the crushing structure below it will be inserted into the filter cartridge 14. The second motor 802 will be started, and the output end of the second motor 802 will drive the rotating rod 804 to rotate accordingly. The multiple blades 805 equidistantly arranged on the surface will crush the agricultural products in the filter cartridge 14 during the rotation. After that, the output end of the first electric telescopic rod 3 will extend upward to separate the crushing assembly 8 from the filter cartridge 14, and the first motor 7 will be started. The output end of the first motor 7 will drive the connecting plate 4 to rotate accordingly, so that the pressing assembly 9 can be transferred to the top of the filter cartridge 14. In this process, For agricultural products with less juice, a proper amount of detection liquid is added. The detection liquid can be liquid such as water. Its function is to soak the crushed agricultural products for a certain period of time so that the pesticides that may remain inside them can be integrated into the detection liquid. Then, the output end of the first electric telescopic rod 3 is retracted again, which makes the second mounting block 901 contact the top of the filter cartridge 14 through the connection of multiple second connecting rods 903. Then, the second electric telescopic rod 902 is started. When the output end of the second electric telescopic rod 902 is extended, it pushes the pressing plate 904. Under the action of pressure, the pressing plate 904 squeezes out the juice in the agricultural products and the detection liquid after soaking. The mixed detection liquid of the juice of the agricultural product flows out from the multiple holes evenly opened on the surface of the filter cartridge 14. Since there is a gap of a certain size between the bottom of the filter cartridge 14 and the inner bottom surface of the placement block 13, the mixed detection liquid of the juice of the agricultural product can flow into the connecting tube 11, and is transported by the connecting tube 11 to the detector body 10 for pesticide residue detection. By crushing and soaking some agricultural products with less water content, and squeezing the soaked agricultural products, less agricultural products can be used to detect the pesticide residue content inside them, avoiding the problem of large amount required when testing such agricultural products with less water content, thereby improving the use effect of the agricultural product pesticide residue detector.

[0026] Embodiment 2, as Figure 1-Figure 4As shown, a square groove is provided at the top of the base 12, and a square protrusion is provided at the bottom of the placement block 13. The outer surface of the protrusion of the placement block 13 fits with the inner surface of the top groove of the base 12. Rubber pads are provided at the bottoms of the first mounting block 801 and the second mounting block 901 near the edges. The cross-sections of the first mounting block 801 and the second mounting block 901 are larger than the top cross-section of the filter cartridge 14.

[0027] The effect achieved by the entire embodiment 2 is that, when cleaning, the filter cartridge 14 is twisted to separate it from the placement block 13, and the inside of the filter cartridge 14 can be cleaned separately. At the same time, the placement block 13 can be directly picked up to separate it from the base 12, and its inner wall can be rinsed with clean water. The multiple blades 805 and the pressing plate 904 can be wiped or a proper amount of clean water can be added to the placement block 13, and normal cleaning can be carried out in conjunction with the telescopic effect of the first electric telescopic rod 3 and the rotation effect of the first motor 7. Since sealing pads are provided at the bottom of the first mounting block 801 and the second mounting block 901 near the edge, when the first mounting block 801 and the second mounting block 901 are in contact with the top of the filter cartridge 14, a sealing effect is played, thereby improving the sealing effect of the agricultural product pesticide residue detector when it is crushed or pressed.

[0028] Working principle: when testing agricultural products, put an appropriate amount of agricultural products into the filter cartridge 14, and choose to directly squeeze or crush and squeeze according to the amount of water contained in the tested agricultural products. When targeting agricultural residues with less water, start the first motor 7, and its output end will drive the connecting plate 4 to rotate accordingly, so that the crushing component 8 is transferred to the top of the filter cartridge 14, and then the first electric telescopic rod 3, when the output end of the first electric telescopic rod 3 is contracted, the mounting plate 6 will slide downward along the outer surface of the two fixed rods 5, and the bottom of the first mounting block 801 will contact the top of the filter cartridge 14, and the crushing structure below it will be inserted into the filter cartridge 14, and the second motor 802 will be started, and the output end of the second motor 802 will drive the rotating rod 804 to rotate accordingly. Multiple blades 805 will crush the agricultural products in the filter cartridge 14 during the rotation process, and the output end of the first electric telescopic rod 3 will extend upward, which will separate the crushing component 8 from the filter cartridge 14, and start the first motor 7. The output end of the first motor 7 will drive the connecting plate 4 to rotate accordingly, so that the pressing component 9 can be transferred to the top of the filter cartridge 14. In this process, An appropriate amount of detection liquid can be added to agricultural products with less juice. The detection liquid can be liquid such as water. Its function is to soak the crushed agricultural products for a certain period of time so that the pesticides that may remain inside them will be integrated into the detection liquid. Then, under the telescopic effect of the output end of the first electric telescopic rod 3, the bottom of the second mounting block 901 will be against the top of the filter cartridge 14, and then the second electric telescopic rod 902 will be started. The output end of the second electric telescopic rod 902 will move the pressing plate 904 downward in the filter cartridge 14. Under the action of pressure, the pressing plate 904 will squeeze out the juice in the agricultural products and the soaked detection liquid. The juice of the agricultural products mixed with the detection liquid flows out from a plurality of holes evenly opened on the surface of the filter cartridge 14, and is transported to the detector body 10 by the connecting pipe 11 for pesticide residue detection. By crushing and soaking some agricultural products with less water content, and squeezing the soaked agricultural products, less agricultural products can be used to detect the pesticide residue content inside them, avoiding the problem of large dosage required when detecting such agricultural products with less water content, thereby improving the use effect of the agricultural product pesticide residue detector.
