Description

Technical Field

[0001] This utility model relates to the field of pesticide detection technology, specifically to a pesticide accelerated dissolution device for detecting pesticide residues in fruits and vegetables. Background Technology

[0002] Fruits and vegetables are indispensable foods in people's daily lives, providing the vitamins needed by the human body to maintain health. During the growth process of fruits and vegetables, farmers spray pesticides to avoid the harm of pests and diseases, thereby ensuring the normal growth of fruits and vegetables and increasing yield. Due to the use of pesticides, some pesticide residues will remain on the surface of fruits and vegetables. These pesticides can cause significant harm to people who consume them. To avoid excessive pesticide residues in fruits and vegetables, health agencies will use sampling to test for pesticide residues. In the testing process, a dissolution device is needed to dissolve the pesticides in the fruits and vegetables into a solvent for subsequent testing.

[0003] Currently, in the process of testing pesticide residues in agricultural products, fruits and vegetables are usually directly soaked in a solvent to dissolve the pesticides. However, since both the pesticides and the fruits and vegetables are in a static state, the solvent near the fruits and vegetables may become saturated and unable to dissolve the pesticides, leaving some pesticides still inside the fruits and vegetables, which leads to inaccurate test data. Utility Model Content

The first drive motor 16 is a forward and reverse motor, which drives the rotating cover 4 to rotate in a regular forward and reverse direction to improve the dissolution efficiency.

[0025] It also includes: several fixing bolts 19 threaded onto the sealing cover 3; several fixing grooves 18 formed on the dissolution tank 1, wherein the sealing cover 3 is fixed when the fixing bolts 19 are set inside the fixing grooves 18; at least two positioning sleeves 21 fixedly set inside the dissolution tank 1, wherein the storage cylinder 2 is slidably set inside the positioning sleeves 21; and a discharge pipe 20 fixedly connected to the dissolution tank 1 at a position near the bottom. By setting the positioning sleeves 21, the storage cylinder 2 can be positioned, thereby improving its stability during movement. The discharge port of the discharge pipe 20 can be sealed by installing accessories such as wooden plugs.

[0026] It also includes: an adjusting cylinder 9, which is fixedly mounted on the axis of the rotating cover 4, and a support plate 5 that is slidably mounted on the outer surface of the adjusting cylinder 9; an adjusting rod 10, which is slidably mounted inside the adjusting cylinder 9, and the other end of the adjusting rod 10 is fixedly mounted on the pressure plate 11; and a threaded through hole 12, which is opened on the adjusting cylinder 9, and a fastening bolt 13 is threadedly connected inside the threaded through hole 12. One end of the fastening bolt 13 presses against the surface of the adjusting rod 10. By adjusting the position of the pressure plate 11 inside the storage cylinder 2, it is convenient to squeeze different kinds of fruits and vegetables.

[0027] This invention provides a device for accelerating pesticide dissolution in the detection of pesticide residues in fruits and vegetables. The specific working principle is as follows:

[0028] During the leaching process, the staff places the fruits and vegetables to be tested into the storage cylinder 2, then covers it with the sealing cap 3. At the same time, the positioning block 8 is inserted into the slot 14, and the sealing cap 3 is fixed by the fixing bolt 19. Then, the first drive motor 16 and the second drive motor 17 are started. The first drive motor 16 drives the rotating cover 4 to rotate, so that the storage cylinder 2 moves with the rotating cover 4. The second drive motor 17 drives the eccentric roller 15 to rotate, so that the eccentric roller 15 causes the storage cylinder 2 to shake up and down intermittently during the rotation. During the shaking, the pressure plate 11 extends into the storage cylinder 2 relative to it, squeezing the fruits and vegetables so that the pesticides in the fruits and vegetables can fully combine with the solvent.
