With the driving of the second motor 19, the first gear 16 will drive the second gear 17 to rotate, so that the turntable 2 at its upper end can rotate, so that the liquid collection cups 5 are moved one by one to the lower end of the injection bottle 24 for injection. The pneumatic injection pump 15 is connected with the injection bottle 24 under the connection of the lower external threaded seat 35. The pneumatic injection pump 15 pushes the liquid to the inner side of the liquid collection cup 5 from the upper part of the interior. After completing the dripping work, the injection bottle 24 needs to be cleaned. The first motor 6 drives the second wheel plate 22 to rotate. Under the connection of the belt 21, the first wheel plate 20 rotates synchronously. At the same time, the second cylinder 10 cooperates to rotate the first wheel plate 20. The first cylinder 9 then drives the pneumatic injection pump 15 and the threaded seat 35 to move upward, and the experimenter slides the slider 31 to one side of the injection bottle 24 and inserts the rubber rod 30 into the injection bottle 24. Under the counter-pressure of the spring 32, the rubber rod 30 fits the inner wall of the injection bottle 24. At this time, the water pipe is connected to the injection pipe 28, which not only flushes the injection pipe 28, but also flushes the inside of the injection bottle 24. Then, the first motor 6 is driven to rotate, so that the injection bottle 24 can rotate by itself and scrape against the internal rubber rod 30 to fully flush the solvent inside the injection bottle 24. Finally, the dirt can be discharged through the nozzle of the injection bottle 24.
