As a preferred embodiment, Figure 2 Figure 3 and Figure 4As shown, a plurality of mounting frames 5 are evenly arranged on the outer side of the upper surface of the mounting substrate 2, and a drawing mechanism for drawing medicine is arranged in the middle of the mounting frame 5. For drawing medicine, a transmission mechanism for driving the drawing mechanism is arranged on the top of the mounting frame 5, and the transmission mechanism can drive the drawing mechanism to work by the rotation of the mixing barrel 3. The transmission mechanism includes a transmission gear 6 and a driving disk 9. The transmission gear 6 is rotatably arranged at the lower part of the right-angle extension frame 501 fixedly arranged on the top of the mounting frame 5, and the transmission gear 6 is meshed and connected with the second gear ring 302 sleeved on the top of the mixing barrel 3. A first bevel gear 7 is fixedly arranged at the lower part of the transmission gear 6, and the first bevel gear 7 is meshed and connected with the second bevel gear 8 rotatably arranged on the side of the right-angle extension frame 501. The driving disk 9 is transmission-connected with the second bevel gear 8 through a transmission shaft, and a plurality of equidistantly distributed adjustment holes 901 are opened on the outer side of the driving disk 9. Different adjustment holes 901 have different center distances from the driving disk 9, and the internal thread of one of the adjustment holes 901 is connected with a driving column 10 matched with the drawing mechanism.

[0025] When mixing medicines, the motor 4 drives the mixing barrel 3 to rotate, and the second gear ring 302 drives the transmission gear 6 to rotate. The transmission gear 6 drives the driving disk 9 to rotate through the first bevel gear 7 and the second bevel gear 8. When the driving disk 9 rotates, the driving column 10 pulls the extraction mechanism to work, so as to extract the medicine. Since the adjustment holes 901 are evenly distributed on the outside of the driving disk 9, different adjustment holes 901 have different center distances from the driving disk 9, so that the installation position of the driving column 10 and the distance at the center of the driving disk 9 can be adjusted according to the adjustment holes 901, so as to adjust the distance that the driving disk 9 pulls the extraction mechanism to run when it rotates.

[0026] The second embodiment of the utility model refers to Figure 4 and Figure 5 As shown, the material extraction mechanism includes a guide block 11 and a medicine suction barrel 12. The medicine suction barrel 12 is fixedly arranged at the outer end of a flat extension frame 502 arranged in the middle of the mounting frame 5. A piston 13 slidably arranged inside the medicine suction barrel 12 is fixedly connected to the middle of the guide block 11 through a pull rod 15. A strip opening opened in the middle of the guide block 11 is slidably connected to a driving column 10. When the driving disk 9 drives the driving column 10 to rotate, the driving column 10 slides and adjusts in the strip opening opened in the middle of the guide block 11, and the guide block 11 pulls the pull rod 15 and the lower parts move up and down, and a check valve is provided at the connecting hole 14 opened on the outside of the piston 13.

[0027] When mixing medicines, the driving disk 9 pulls the pull rod 15 through the driving column 10 and the guide block 11 to move up and down, so that the piston 13 slides up and down inside the medicine suction barrel 12. When the piston 13 slides upward, the check valve at the connecting hole 14 is closed, and the piston 13 pushes the medicine above into the mixing barrel 3 through the medicine outlet pipe 16. When the piston 13 slides downward, the medicine below the mixing barrel 3 pushes up the check valve, and the medicine enters the upper part of the mixing barrel 3 through the connecting hole 14, so that the medicine is sucked out by the up and down movement of the piston 13. When the driving column 10 is adjusted to different adjustment holes 901, the center distance between the driving column 10 and the driving disk 9 changes, so that the driving column 10 changes the distance by which the pull rod 15 and the piston below move up and down through the guide block 11, and then the volume of the medicine drawn into the mixing barrel 3 per rotation of the driving disk 9 can be adjusted, so that the driving column 10 can be adjusted to different adjustment holes 901, so that the medicine suction barrel 12 can draw different medicines into the mixing barrel 3 in proportion for mixing.

[0028] After the medicine enters the mixing barrel 3, in order to accelerate the mixing of the medicine, Figure 2 and Figure 3 In the third embodiment of the utility model, a fixed shaft 17 is fixedly provided in the middle of the upper surface of the mounting base 2, the upper end of the fixed shaft 17 is rotatably connected to the bottom of the mixing barrel 3 through a sealed bearing, and a stirring blade is provided on the top of the fixed shaft 17.

[0029] When the mixing barrel 3 rotates, the fixed shaft 17 and the stirring blades are fixed, so that the mixing barrel 3 drives the medicine to rotate while the stirring blades can stir the medicine to accelerate the mixing of the medicine.
