Description

Technical Field

[0001] This utility model relates to the field of food safety, and in particular to a pretreatment device for rapid detection of pesticide residues. Background Technology

[0002] In the food safety regulatory system, pesticide residue testing of fruits and vegetables is a crucial link in protecting consumer health. The accuracy and efficiency of the test results largely depend on the standardization and convenience of the pretreatment process. Currently, the pretreatment process for pesticide residue testing of fruits and vegetables generally suffers from problems such as fragmented operations, low automation, and insufficient processing efficiency, making it difficult to meet the needs of large-scale and rapid testing.

[0003] Existing rapid pesticide residue detection pretreatment devices typically involve adding fruit and vegetable samples into the device and crushing them to facilitate subsequent liquid extraction and detection. However, to ensure the accuracy of the detection, the fruit and vegetable samples are usually washed before crushing. Current devices can only crush the fruit and vegetable samples and cannot wash them, requiring manual cleaning, which is cumbersome, inefficient, and inconvenient.

[0004] Therefore, it is necessary to design a pretreatment device for rapid detection of pesticide residues that can facilitate the washing, crushing, conveying, and collection of fruits and vegetables, thereby improving processing efficiency. Utility Model Content

The box 2 is slidably attached to the lower front of the base 1. The box 2 has a handle on its front side for easy gripping. The filter housing 3 is connected to the lower right of the base 1. The filter housing 3 has a slag inlet on its left side for easy entry of water and slag. The first outer shell 4 is connected to the left side of the base 1. The second outer shell 5 is connected to the upper side of the base 1 and is connected to the first outer shell 4. A water pump 6 is connected to the upper right side, and the water pump 6 is connected to the filter box 3 through a pipe. A third outer shell 8 is connected to the upper left side of the second outer shell 5. A spray frame 9 is connected to the upper part of the third outer shell 8. A water pipe 7 is connected between the spray frame 9 and the water pump 6. A first motor 10 is connected to the rear side of the third outer shell 8. The first motor 10 and the processor are electrically connected through a control module. A guide pipe 11 is connected to the lower right side of the third outer shell 8. The front and rear parts of the box 2 are slidably connected to the cover 12. A second connecting plate 19 is connected to the output shaft of the first motor 10. A locking component is provided between the covers 12. A crushing component is provided inside the first outer shell 4.

[0024] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the locking assembly includes a knob 13, a connecting rod 14, a slider 15, a first connecting plate 16, a first spring 17, and a fixing rod 18. The knob 13 is rotatably connected to the front cover 12. The knob 13 has anti-slip texture for easy gripping. The connecting rod 14 is connected to the rear side of the knob 13. The connecting rod 14 passes through the rear cover 12. The first connecting plate 16 is slidably connected to the rear of the connecting rod 14. The slider 15 is connected to the upper side of the first connecting plate 16. Two first springs 17 are connected between the first connecting plate 16 and the connecting rod 14. Two fixing rods 18 are connected to the lower rear side of the first connecting plate 16. The fixing rods 18 pass through the connecting rod 14 and engage with the rear cover 12.

[0025] like Figure 5 As shown, it also includes a crushing assembly, which includes a cutting blade 20, a spiral conveyor shaft 21, a second spring 22, a second motor 23, and a third connecting plate 24. The second motor 23 is connected to the bottom of the first housing 4. The second motor 23 and the processor are electrically connected through a control module. The spiral conveyor shaft 21 is connected to the output shaft of the second motor 23. The cutting blade 20 is connected to the upper side of the spiral conveyor shaft 21. The third connecting plate 24 is slidably connected to the lower part of the first housing 4. Four second springs 22 are connected between the third connecting plate 24 and the first housing 4.

[0026] When using this device, first place the base 1 in the fruit and vegetable processing area, then put the fruits and vegetables to be processed into the third outer shell 8, and then start the water pump 6 so that the water in the filter box 3 is sprayed out from the spray frame 9 through the water pipe 7, and the fruits and vegetables are washed by the spray frame 9. The sewage in the third outer shell 8 flows back to the filter box 3 through the guide pipe 11, and the sewage is filtered and purified by the filter box 3. After the washing is completed, the processor starts the first motor 10 through the control module, which drives the second connecting plate 19 to rotate and open, so that the fruits and vegetables fall into the first outer shell 4. Then, the second motor 23 is started to drive the spiral conveyor shaft 2. 1. The cutting blade 20 rotates, crushing the fruits and vegetables. The crushed fruits and vegetables are then conveyed downwards by the screw conveyor shaft 21, causing them to squeeze the third connecting plate 24 and move it downwards. The second spring 22 is compressed and contracts, opening the lower right part of the first outer shell 4 and allowing the crushed fruits and vegetables to be discharged into the box 2. This facilitates the washing, crushing, conveying, and collection of fruits and vegetables, improving processing efficiency. When the third connecting plate 24 is no longer squeezed, the second spring 22 returns to its original position, causing the third connecting plate 24 to move upwards and reset, sealing the discharge port on the first outer shell 4. When it is necessary to take the fruit and vegetable samples in box 2 to another location, the lid 12 can be moved inward to close, and then the slider 15 can be moved forward, causing the first connecting plate 16 and the fixing rod 18 to move forward. The first spring 17 is compressed and contracted. Then, the knob 13 is turned, causing the connecting rod 14 to rotate. After rotating to a certain position, the slider 15 is released, the first spring 17 returns to its original position, and the first connecting plate 16 and the fixing rod 18 move backward, so that the fixing rod 18 engages with its adjacent lid 12, locking the lids 12 together. Then, the box 2 can be moved forward to take it out and carry it, thus making it convenient to carry the collected fruit and vegetable samples. It is easy to use.
