Through the cooperation of the motor 11, the driving gear 12 and the driven gear 10, the fixed shaft 9 and the material bin 13 can be driven to rotate.

[0023] A plurality of brackets 15 are fixedly connected to the upper edge of the base 1, and a support plate 16 is fixedly connected among the plurality of brackets 15. A hydraulic cylinder 17 is fixedly installed on the upper end of the support plate 16. The piston rod of the hydraulic cylinder 17 penetrates through the support plate 16 and is slidably connected to the support plate 16. The end of the piston rod is fixedly connected to a piston disk 18, and the piston disk 18 is slidably connected inside the material bin 13. By pushing the piston disk 18 through the hydraulic cylinder 17, the solvent inside the material bin 13 can be pressurized.

[0024] An automatic opening and closing mechanism 3 is arranged inside the shunt pipe 14. Through the setting of the automatic opening and closing mechanism 3, after adding the solvent inside the material bin 13 into the extraction column 8, it can play a role in preventing overflow of materials. The automatic opening and closing mechanism 3 includes a tapered pipe 31 fixedly connected to the inside of the shunt pipe 14. A plug 32 is slidably connected to the lower inner side of the tapered pipe 31. A partition net 33 is fixedly connected to the upper part inside the shunt pipe 14. A sleeve 34 is fixedly connected to the lower end of the partition net 33. A sliding rod 35 is slidably connected to the inside of the sleeve 34.

Subsequently, the linkage disk 6 is pushed downward, causing each support base 7 to move downward. Then, the extraction columns 8 are sequentially placed into the corresponding support bases 7, and the pressure on the linkage disk 6 is removed. Subsequently, the linkage disk 6 resets under the action of the first spring 5 and drives the support base 7 to rise. The top of the extraction column 8 then abuts against the docking pipe 2. Then, the hydraulic cylinder 17 is used to push the piston disk 18 downward, and the solution in the material bin 13 is pressurized by the piston disk 18. The pressurized solution enters the current docking pipe 2 through the shunt pipe 14 and then flows downward to the extraction column 8. Subsequently, the motor 11, through the cooperation of the driving gear 12 and the driven gear 10, causes the fixed shaft 9 and the material bin 13 to rotate, and then the solution is filled into the next extraction column 8. This process is repeated, with a relatively high degree of automation and continuity. In addition, when the solution is pressurized and enters the shunt pipe 14, it will push open the plug 32 by means of the pressure. When the solution filling is completed, the plug 32 will automatically reset under the action of the second spring 36, thereby playing a role in preventing overflow of materials and avoiding waste.
