Description

Technical Field

[0001] This utility model relates to the field of auxiliary testing device technology, specifically to a pesticide effervescent tablet toxicity testing device. Background Technology

[0002] Effervescent pesticide tablets, as a highly efficient and environmentally friendly pesticide formulation, offer advantages such as rapid dissolution, high utilization rate of active ingredients, and ease of use, leading to their increasingly widespread application in modern agricultural pest and disease control. However, after application, effervescent pesticide tablets can enter water bodies or soil environments through rainwater runoff and soil infiltration, potentially posing harm to non-target organisms and ecosystems. Therefore, before being marketed, effervescent pesticide tablets must undergo rigorous toxicity testing to verify their environmental safety and ensure that their toxicity to non-target organisms meets relevant national standards.

[0003] When conducting toxicity tests on pesticide effervescent tablets, the tablets are usually dissolved in water to form a test solution. Test organisms are then placed in the solution to observe their physiological reactions. However, pesticide effervescent tablets are prone to local aggregation during the dissolution process, leading to uneven concentration distribution and deviations in liquid concentration. This affects the scientific validity of pesticide safety evaluation. Furthermore, during the test, vibrations from the stirring device or accidental contact by operators can easily cause the container holding the test solution to shift or tip over, posing a safety hazard.

[0025] To facilitate uniform mixing of pesticide effervescent tablet solutions, combined with... Figure 1 Appendix Figure 2 and attached Figure 3 A pesticide effervescent tablet toxicity testing device includes a base 1, with an inverted L-shaped plate 2 on one side of the top of the base 1, and further includes an electric telescopic rod 4 and a barrel 11. The electric telescopic rod 4 is located at the top of the L-shaped plate 2, and a housing 5 is provided at the telescopic end of the electric telescopic rod 4. The barrel 11 is placed at the top of the base 1, and a barrel cover 6 is provided at the bottom of the housing 5. A stirring structure for use with the barrel 11 is provided at the bottom of the barrel cover 6. The stirring structure includes a motor 7, a stirring rod 8, and stirring blades 9. The motor 7 is located inside the housing 5, the stirring rod 8 is rotatably connected to the barrel cover 6, and the top of the stirring rod 8 extends into the housing 5 and is connected to the output end of the motor 7. Several stirring blades 9 are evenly distributed on both sides of the stirring rod 8.

[0026] By extending and retracting the electric telescopic rod 4, the box body 5 and the lid 6 can be raised and lowered synchronously, realizing the rapid docking and separation of the stirring structure and the barrel 11. Moreover, the motor 7 drives the stirring rod 8 and the stirring blade 9 to rotate continuously, which can continuously stir the pesticide effervescent tablet solution in the barrel 11 to ensure uniform mixing. The structure is simple and easy to use.

[0027] In order to fix the barrel 11 and improve the accuracy of the test data, combined with the attached... Figure 1 and attached Figure 4 The fixing components are used to reinforce the barrel 11 and are located on both sides of the top end of the base 1. The fixing components include limiting plates 12 and limiting rods 13.

The two limiting plates 12 are respectively sleeved on the limiting rods 13 on both sides, and the top end of each limiting rod 13 is provided with a threaded connecting cap 14. The top end of the base 1 is provided with a groove 10, and the barrel 11 is directly placed in the groove 10. A control panel 3 is provided on one side of the base 1.

[0028] The barrel 11 is placed directly in the groove 10, so that the limiting plates 12 on both sides are respectively fitted onto the limiting rod 13. After tightening, the limiting plates 12 can be pressed and fixed, thereby achieving a firm positioning of the barrel 11 and effectively preventing the barrel from shifting or tipping due to stirring vibration or external force.

[0029] In specific implementation of this utility model:

[0030] First, place the barrel 11 into the groove 10 of the base 1, align the limiting plates 12 on both sides of the barrel with the limiting rod 13 and put them on it; manually tighten the connecting cap 14 at the top of the limiting rod 13 until the limiting plate 12 is pressed and the barrel 11 cannot move.

[0031] Next, add a preset volume of standard dilution water into the barrel 11, then add a measured amount of pesticide effervescent tablets, start the electric telescopic rod 4, the electric telescopic rod 4 drives the box 5 and the barrel lid 6 to descend, so that the stirring rod 8 and stirring blade 9 extend into the solution in the barrel 11 until the barrel lid 6 is in contact with the opening of the barrel 11, then stop the electric telescopic rod 4.

[0032] Then, start motor 7. Motor 7 drives stirring rod 8 and stirring blade 9 to rotate continuously, which can continuously stir the pesticide effervescent tablet solution in barrel 11 to ensure uniform mixing, avoid deviations in toxicity test caused by local concentration differences, and ensure the accuracy of toxicity test data.
