[0013] Example 1

[0014] like Figure 1-3 As shown, a quantitative dropping experimental device for multiple reagents includes a box body 1 with a door opened at the front side, a test tube 9 and a syringe 13. A plurality of test tubes 9 are used, which are evenly placed on a test tube placement plate 8 in a circumferential direction. The number of syringes 13 is the same as the number of test tubes 9. The plurality of syringes 13 contain different reagents. A piston 14 is provided in the syringe 13. The plurality of syringes 13 are placed on a syringe placement plate 15 and are evenly arranged in a circumferential direction. The syringes 13 are limited by the top annular platform and the syringe placement plate 15. The syringe placement plate 15 is fixedly connected to a gear ring 16. The gear ring 16 is connected to the mounting plate 21 through a slewing bearing 17, and a driving gear 18 meshing with the outer teeth of the gear ring 16 is fixedly connected to a driving motor 19. The driving motor 19 is fixedly connected to the inner wall of the box body 1 through a motor frame 20. The syringe 13 can pass through the inner hole of the gear ring 16 and the inner hole set on the mounting plate 21. An electric cylinder 22 is installed on the top of the box body 1. The end of the cylinder rod of the electric cylinder 22 is fixedly connected to a cylindrical pressure block 23. The cylinder rod of the electric cylinder 22 is facing the frontmost syringe 13 and the cylinder rod can drive the piston 14 to move downward.

[0015] The controller controls the driving motor 19 to rotate, and drives the gear ring 16 to rotate through the driving gear 18, thereby realizing the rotation of the syringe 13. When the reagent to be added rotates to the bottom of the electric cylinder 22, it stops. The controller controls the lever of the electric cylinder 22 to extend, and drives the piston 14 to move downward, so as to drip the reagent into the test tube 9.

[0016] The test tube placement plate 8 is connected to the support column 7 arranged on the support plate 6 through multiple compression springs 10. A vibrator 11 is installed at the bottom of the test tube placement plate 8. The support plate 6 is installed on the output disc of the electric turntable 5. The test tube 9 or the syringe 13 can be aligned after rotation. The electric turntable 5 is installed on the lifting plate 2. The two sides of the lifting plate 2 are connected to the left and right side walls of the box body 1 through the slider guide pair 3. The middle part of the bottom side of the lifting plate 2 is connected to the cylinder rod of the electric cylinder 4, and the cylinder seat of the electric cylinder 4 is fixedly connected to the bottom plate inside the box body 1.

[0017] The controller controls the electric turntable 15 to rotate or the lifting plate 2 to rise, which is conducive to the alignment of the test tube 9 and the syringe 13 after rotation, and the reagent is accurately added to the test tube 9. The test tube placement plate 8 is connected to the support column 7 set on the support plate 6 through multiple compression springs 10. Starting the vibrator 11 can achieve shaking of the test tube 9, which is conducive to the mixing reaction of the medicine.

[0018] In order to facilitate taking out the piston 14 for adding reagents, an I-shaped connecting column 24 is installed on the top of the piston 14.

[0019] Due to the low temperature at night, a heating device 12 and a temperature sensor are installed on the rear side of the box 1. The heating device 12 adopts a serpentine heating coil. The temperature is monitored by the temperature sensor to control the heating of the heating device 12 to prevent the experimental environment temperature from being too low at night, causing a temperature difference that affects the experimental results.

[0020] Instructions for use: Place the test tube 9 containing the test reagent on the test tube placement plate 8, and place the reagent to be added during the test in the syringe 13. Through the controller parameter setting, at the set time, the drive motor 19 or the electric turntable 15 is started, the corresponding test tube 9 and the syringe 13 are rotated and aligned, and the lever of the electric cylinder 22 extends to drive the piston 14 downward to squeeze the reagent out of the syringe 13 to achieve the reagent addition. Similarly, the step-by-step addition of different reagents can be achieved. It solves the problem that the current experiment needs staff to supervise the addition of reagents when the experiment takes a long time, especially in the middle of the night without manual operation, reduces the workload of experimental operators, and liberates manpower.
