And to ensure the reliability of experimental data, it is usually necessary to determine the amount of chemical reagents used. Therefore, the quantitative feeding device plays a crucial role in the entire analysis process.

[0003] A quantitative feeding device for chemical analysis disclosed in the Chinese utility model patent application publication specification CN 214636219 U has accurate quantification. However, during feeding, it can only be fed manually. Manual feeding is relatively slow, and manual operation is prone to errors, resulting in errors in the feeding amount. Therefore, there is a problem of slow manual feeding speed. And when replenishing raw materials into the feeding pipe, it can only be replenished after removing the pipe cap, and this method is relatively cumbersome and not convenient enough. Therefore, there is a problem that the replenishment of raw materials is relatively cumbersome. In summary, this utility model has the problems of slow manual feeding speed and relatively cumbersome replenishment of raw materials. Content of the Utility Model

[0028] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a quantitative feeding device for chemical chemical analysis, including a fixed frame 1, a placing table 6 is fixedly connected to the top of the fixed frame 1, a feeding box 2 is fixedly connected to one end of the fixed frame 1, a first spring 17 is fixedly connected to the inner wall of the feeding box 2, a movable strip 16 is fixedly connected to the top of the first spring 17, a first blocking plate 19 is fixedly connected to the bottom of the movable strip 16, a first sealing ring 18 is movably connected to the outside of the first blocking plate 19, the first sealing ring 18 is fixedly connected to the feeding box 2 on the outside, the top of the movable strip 16 is in a cross shape, the number of the first springs 17 is two, the first springs 17 are annularly distributed on the movable strip 16, a driving motor 10 is fixedly connected to the inner wall of the feeding box 2, and a remaining amount mark 5 is arranged on the front side of the feeding box 2;

[0029] The output shaft of the driving motor 10 is fixedly connected with a second gear 9. The outer side of the second gear 9 is meshed and connected with a first gear 8. The inner wall of the first gear 8 is threadedly connected with a threaded rod 7. The bottom of the threaded rod 7 is fixedly connected with a discharge plate 11. The outer side of the discharge plate 11 is fixedly connected with a sealing strip 12. The outer side of the sealing strip 12 is slidably connected with a feeding box 2. The top of the threaded rod 7 is fixedly connected with an opposing strip 3. The inner wall of the opposing strip 3 is fixedly connected with a second electrode block 15. One end of the second electrode block 15 is movably connected with a first electrode block 14. The outer side of the first electrode block 14 is fixedly connected with the feeding box 2;

[0030] The inner wall of the discharge plate 11 is fixedly connected with a second spring 20. The bottom of the second spring 20 is fixedly connected with a connecting piece 21. The bottom of the connecting piece 21 is fixedly connected with a second blocking plate 23. The outer side of the second blocking plate 23 is fixedly connected with a second sealing ring 22.

[0031] During use, start the driving motor 10 to rotate forward through an external control panel, so that the second gear 9 rotates. Since the second gear 9 is meshed with the first gear 8, the threaded rod 7 moves downward. The discharge plate 11 pushes the raw materials inside the feeding box 2 downward. The movable strip 16 moves downward, and the first spring 17 contracts, causing the first blocking plate 19 to be misaligned with the convex block inside the discharge port at the bottom of the feeding box 2, so that the raw materials are discharged. The raw materials enter the sampling bottle on the placement table 6. Under the drive of the threaded rod 7, the opposing strip 3 makes the feeding hopper 4 move synchronously with the discharge plate 11. When the discharge plate 11 reaches the specified position, the first electrode block 14 and the second electrode block 15 come into contact, and the driving motor 10 is turned off, thereby discharging quantitatively.
