Description

Technical Field

[0001] This utility model relates to the field of pesticide residue detection technology, and in particular to a test tube oscillation device suitable for pesticide residue detection. Background Technology

[0002] Pesticide residues refer to the total amount of impurities, including derivatives, metabolites, parent pesticides, and degradation products, that remain in the environment, organisms, and food after pesticide use. The main pesticides causing excessive pesticide residues in vegetables are organophosphorus pesticides and carbamate pesticides banned in vegetable production in some countries, such as parathion, methamidophos, phorate, dimethoate, and methyl parathion. Consuming vegetables with excessive pesticide residues poses a serious threat to human health, easily causing acute poisoning and even death.

[0003] In pesticide residue detection, test tube shaking is an important step in sample pretreatment. Test tubes containing samples and mixtures are fixed on a reciprocating shaker and shaken to mix. After shaking, the solution is extracted for pesticide residue detection. During sample shaking, some samples have high viscosity and density, while others have low viscosity. The shaking amplitude is constant and cannot be adjusted according to requirements. Therefore, a test tube shaking device suitable for pesticide residue detection is proposed. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A test tube shaking device suitable for pesticide residue detection includes a shaking base, a connecting plate movably mounted on the shaking base, a rotating shaft rotatably mounted on the top of the connecting plate, a vibration placement plate fixedly mounted on the top of the rotating shaft, a test tube body placed on the vibration placement plate, a rotating disk mounted on the top of the shaking base via a rotation drive assembly, a connecting rod mounted on the rotating disk via a position adjustment and fixing assembly, the connecting rod being rotatably connected to one side of the connecting plate, and an automatic rotation assembly provided between the shaking base and the rotating shaft.

[0006] Preferably, the top of the vibration placement plate is provided with multiple placement slots, the inner wall of the placement slots is provided with protective pads, the test tube body is placed in the placement slots, and the top of the test tube body is installed with a top sealing cap.

[0007] Preferably, the rotary drive assembly includes a rotary motor mounted on the oscillation base, with the output end of the rotary motor fixedly connected to the bottom of the rotating disk.

[0008] Preferably, the position adjustment and fixing assembly includes a first threaded groove, a second threaded groove and a third threaded groove formed on the top of the rotating disk, and a fixing bolt is threaded onto the first threaded groove.

[0009] Preferably, the fixing bolt is externally fixed with an installation collar, and the end of the connecting rod is fixedly installed with a connecting sleeve, which is movably fitted onto the installation collar.

[0010] Preferably, the automatic rotation component includes a rack fixedly mounted on the top of the oscillating base, and a gear fixedly sleeved on the rotating shaft, the gear meshing with the rack.

[0011] Preferably, the top of the oscillation base is provided with a convex groove, and the bottom of the connecting plate is fixedly installed with a convex slider, which is slidably installed in the convex groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the test tube oscillation device suitable for pesticide residue detection is equipped with a rotation drive component that can drive the rotating disk to rotate. Under the driving action of the fixing bolt and connecting rod, it can drive the placed test tube body to shake. The automatic rotation component vibrates the test tube body on the placement disk to rotate. The test tube body can also shake while rotating, thereby performing effective oscillation. The position adjustment and fixing components are set up so that the vibration amplitude needs to be adjusted when the viscosity and density of some samples are high or low. The fixing bolts are fixed in different threaded grooves. When the rotating disk rotates once, the back-and-forth movement range of the vibration placement disk is different, resulting in different oscillation amplitudes. By setting the threaded grooves at different radius positions, the vibration amplitude can be adjusted to meet the oscillation of samples with different viscosities and densities and improve the oscillation speed.

[0017] Furthermore, the top of the vibrating placement tray 6 is provided with multiple placement slots 7, and protective pads 8 are provided on the inner wall of the placement slots 7. The test tube body 9 is placed in the placement slot 7, and a top sealing cap 10 is installed on the top of the test tube body 9. The product sample to be tested is placed in the test tube body 9, and a mixture is added. The top sealing cap 10 is then closed, and the test tube body 9 is placed on the vibrating placement tray 6. The protective pads 8 can play a role in protecting against shaking and avoid damage to the test tube body 9.

[0018] Furthermore, the rotary drive assembly includes a rotary motor 11 mounted on the oscillation base 1. The output end of the rotary motor 11 is fixedly connected to the bottom of the rotating disk 12. A convex groove 2 is provided on the top of the oscillation base 1. A convex slider 3 is fixedly installed on the bottom of the connecting plate 4. The convex slider 3 is slidably installed in the convex groove 2. When the rotary motor 11 is started, it drives the rotating disk 12 to rotate. At this time, under the action of the fixing bolt 16, the connecting rod 19 can be moved, and the rotating disk 12 rotates, thereby driving the connecting plate 4 to move back and forth. Through the back and forth movement, the test tube body 9 placed thereon can be shaken. The convex groove 2 and the convex slider 3 can limit the position of the connecting plate 4.

[0019] Furthermore, the automatic rotation component includes a rack 21 fixedly mounted on the top of the oscillating base 1, and a gear 20 fixedly sleeved on the rotating shaft 5. The gear 20 meshes with the rack 21. During the back-and-forth movement of the connecting plate 4, the gear 20 is driven to move. Under the meshing action of the rack 21, the gear 20 will rotate, thereby driving the rotating shaft 5 to rotate. The test tube body 9 on the vibration placement plate 6 can also rotate. While rotating, the test tube body 9 can also shake, thereby performing effective oscillation.

[0020] Furthermore, the position adjustment and fixing assembly includes a first threaded groove 13, a second threaded groove 14, and a third threaded groove 15 formed on the top of the rotating disk 12. A fixing bolt 16 is threaded onto the first threaded groove 13, and an installation collar 17 is fixedly sleeved on the outside of the fixing bolt 16. A connecting sleeve 18 is fixedly installed at the end of the connecting rod 19, and the connecting sleeve 18 is movably sleeved on the installation collar 17. When the viscosity and density of some samples are high or low, it is necessary to adjust the vibration amplitude. The rotating disk 12 is provided with the first threaded groove 13, the second threaded groove 14, and the third threaded groove 15, and the radius of the three threaded grooves gradually increases. In addition, during normal oscillation, the fixing bolt 16 is threadedly installed in the second threaded groove 14. When the sample viscosity and density are high, the fixing bolt 16 is threadedly fixed in the third threaded groove 15. When the sample viscosity and density are low, the fixing bolt 16 is threadedly fixed in the first threaded groove 13. By fixing it in different threaded grooves, the back-and-forth movement range of the vibration placement disk 6 is different when the rotating disk 12 rotates once, resulting in different oscillation amplitudes. By setting threaded grooves at different radius positions, the vibration amplitude can be adjusted to meet the oscillation requirements of samples with different viscosities and densities, thereby increasing the oscillation speed.

[0021] In use: During pesticide residue testing, the test tube body 9 is placed on the vibrating placement plate 6. The rotating motor 11 is started, driving the rotating plate 12 to rotate. Under the action of the fixing bolt 16, the connecting rod 19 can be moved, thereby driving the connecting plate 4 to move back and forth. Through the back and forth movement, the placed test tube body 9 can be shaken. During the movement of the gear 20, under the meshing action of the rack 21, the test tube body 9 on the vibrating placement plate 6 can also rotate. The test tube body 9 can shake while rotating, thus performing effective oscillation. When the viscosity and density of some samples are high or low, it is necessary to adjust the vibration amplitude. The rotating plate 12 is provided with a first threaded groove 13, a second threaded groove 14, and a third threaded groove 15. By being fixedly installed in different threaded grooves, when the rotating plate 12 rotates one revolution, the back and forth movement range of the vibrating placement plate 6 is different, thus producing different oscillation amplitudes. By setting threaded grooves at different radius positions, the vibration amplitude can be adjusted, thereby meeting the oscillation of samples with different viscosities and densities, improving the oscillation speed, and making it convenient to use.
