[0017] Example: Figure 1-8 As shown, this utility model provides a special pulverizing and mixing device for drug testing, including a pulverizing mechanism 1. The pulverizing mechanism 1 includes a shell 10, a filter barrel 11 in the middle of the shell 10, a cover plate 12 at the top of the filter barrel 11, a cover plate 14 at the top of the cover plate 12, a pulverizing structure 16 rotatably installed in the middle of the cover plate 14, a feeding pipe 17 at the bottom of the filter barrel 11, the feeding pipe 17 being fixedly connected to the shell 10, a mixing barrel 2 at the bottom of the shell 10, a cover plate 21 at the top of the mixing barrel 2, the cover plate 21 being fixedly connected to the feeding pipe 17, a stirring rod 23 rotatably installed in the middle of the cover plate 21, and the shell 10 being fixedly connected to the cover plate 21 by three evenly distributed annular support rods. The outer shell 10 is provided with four ring-shaped quick-release mechanisms 3 evenly distributed on the outside. The quick-release mechanisms 3 are used to fix the cover plate 12, cover plate 14 and the outer shell 10. The outside of the mixing tank 2 is provided with four ring-shaped quick-release mechanisms 2 4, which are used to fix the cover plate 3 21 to the mixing tank 2. The filter barrel 11 is equipped with a shaking mechanism 5 on its exterior, which is used to shake the filter barrel 11. The crushing structure 16 is driven by a drive motor, and the drive end of the drive motor is connected to the crushing structure 16 through a coupling. The top of the cover plate 2 14 is equipped with a medicine feeding pipe 1. The bottom of the mixing barrel 2 is shaped like a frustum, and a discharge pipe is installed at the bottom. A control valve is installed on the outside of the discharge pipe. The upper and lower parts of the discharge pipe 17 are cylindrical, and the middle part is shaped like a frustum. The filter barrel 11 is composed of a hollow column and a screen, which are fixedly connected by screws. The mixing barrel 2 is supported by four evenly distributed ring-shaped support legs. The top of the cover plate 3 21 is equipped with a solvent (liquid) feeding pipe 2. In actual use, the bottom of the filter barrel 11 is located in the discharge pipe 17.

[0018] The quick-release mechanism 13 includes a fixed base 31, which is fixedly connected to the outer shell 10. An L-shaped rod 32 is provided in the middle of the fixed base 31. Round rods 33 are fixedly installed on both the upper and lower sides of the L-shaped rod 32. A spring 34 is provided on the outside of the L-shaped rod 32. One end of the spring 34 contacts the round rod 33, and the other end of the spring 34 is fixedly connected to the inner wall of the fixed base 31. Four evenly distributed annular insert rods 35 are fixedly installed at the bottom of the cover plate 14. The bottom end of the insert rods 35 is provided with a circular groove 36 that works with the L-shaped rod 32. Four evenly distributed annular cylinders 38 are fixedly installed on the outside of the cover plate 12. The bottom end of the cylinders 38 is provided with a circular groove 39 that works with the L-shaped rod 32. The quick-release mechanism 24 includes four evenly distributed annular insert rods 240. The bottom end of each insert rod 240 has a through-hole circular groove 341. Four evenly distributed annular fixing seats 242 are fixedly installed on the outside of the mixing tank 2. The internal structure of the fixing seat 242 is the same as that of the fixing seat 131. The L-shaped rod 32 works in conjunction with the circular groove 341. By setting up the quick-release mechanism 13, the L-shaped rod 32 is pulled to disengage from the circular groove 136 of the insert rod 135 and the circular groove 239 of the cylinder 38, and the cover plate 214 and cover plate 12 can be quickly removed. The disassembly method between the cover plate 321 and the mixing tank 2 is the same, so that the L-shaped rod 32 is disengaged from the circular groove 341, thus eliminating the need for tools, improving disassembly efficiency, and facilitating the cleaning of the filter tank 11, the pulverizing structure 16, and the stirring rod 23 by the operator.

[0019] The shaking mechanism 5 includes four evenly distributed annular fixed blocks 50. Cover plate 12 is slidably connected to the fixed blocks 50 via T-shaped blocks. The fixed blocks 50 are fixedly connected to the filter barrel 11. A moving rod 51 is fixedly installed in the middle of the fixed blocks 50. The moving rod 51 is slidably connected to cover plate 12 and cover plate 2 14. A roller 52 is rotatably installed at the bottom of the moving rod 51 via a U-shaped block. A circular ring 53 is rotatably installed on the outside of the feed pipe 17. A circular plate 54 is fixedly installed on the outside of the circular ring 53. Four evenly distributed annular wedges 55 are fixedly installed at the top of the circular plate 54. The wedges 55 cooperate with the rollers 52. By setting up the shaking mechanism 5, the rotation of the circular plate 54 drives the wedges 55 to rotate. The wedges 55 cooperate with the rollers 52 to push the moving rod 51 up and down, causing the filter barrel 11 to shake. This achieves the shaking of the filter barrel 11, preventing the pulverized medicine from failing to enter the mixing barrel 2 in time due to the filter barrel 11 being blocked, thus improving the overall efficiency.

[0020] The movable rod 51 is provided with a second spring 58. One end of the second spring 58 is fixedly connected to the cover plate 12, and the other end of the second spring 58 is fixedly connected to the fixing block 50. By setting the second spring 58, when the movable rod 51 moves up and down, the second spring 58 will also contract up and down, thereby increasing the shaking frequency of the filter barrel 11 and improving the filtration effect of the filter barrel 11.

[0021] A dual-shaft motor 25 is fixedly installed on the top of the cover plate 21. One drive end of the dual-shaft motor 25 is fixedly installed with a drive shaft 57 through a coupling. The drive shaft 57 is rotatably connected to the outer casing 10. The drive shaft 57 is connected to the ring 53 through a gear meshing transmission. The other drive end of the dual-shaft motor 25 is fixedly connected to the stirring rod 23 through a coupling. By setting the dual-shaft motor 25, the dual-shaft motor 25 can simultaneously drive the drive shaft 57 and the stirring rod 23 to rotate.

[0022] Limiting blocks 30 are fixedly installed on the inner wall surface of each fixed seat 1 31 and fixed seat 2 42. By setting the limiting blocks 30, the L-shaped rod 32 is first pulled away from the circular groove 1 36 and circular groove 2 39, and then the L-shaped rod 32 is rotated 90 degrees. Then the circular rod 33 is in contact with the limiting blocks 30, thereby preventing the spring 1 34 from causing the L-shaped rod 32 to rebound and affecting the lifting of the cover plate 1 12, cover plate 2 14 and cover plate 3 21.

[0023] A sealing ring is installed between the cover plate 21 and the mixing tank 2; by setting the sealing ring, the sealing between the cover plate 21 and the mixing tank 2 is increased, and the liquid is prevented from overflowing when the pulverized medicine is mixed with the solvent (liquid).

[0024] A handle 6 is fixedly installed on the top of the cover plate 14; by setting the handle 6, it is easy to pick up the cover plate 14 to clean the crushing structure 16.

[0025] Working principle: In actual use, when it is necessary to clean the crushing mechanism 1, manually pull the L-shaped rod 32 in the quick-release mechanism 3 to compress the spring 34, so that the L-shaped rod 32 disengages from the corresponding circular groove 36 and circular groove 39. Then rotate the L-shaped rod 32 to 90°, and the circular rod 33 fits against the internal limiting block 30 of the fixed seat 31 to prevent the spring 34 from rebounding. Then, take the cover plate 14 and the crushing structure 16 out of the filter barrel 11 through the handle 6, and take the insertion rod 35 out of the cylinder 38. Then take the cover plate 12 out of the outer shell 10. When the cover plate 12 is taken out, under the action of the T-shaped block, the filter barrel 11 is taken out of the outer shell 10 for cleaning. When removing the cover plate 321 from the mixing tank 2, pull the L-shaped rod 32 in the quick release mechanism 24 to disengage the L-shaped rod 32 from the circular groove 341. Then lift the outer shell 10 upwards, which will drive the support rod, cover plate 321, and dual-shaft motor 25 to move upwards, so that the stirring rod 23 can be taken out of the mixing tank 2 and the stirring rod 23 and the mixing tank 2 can be cleaned. A measured quantity of tablet-shaped medicine is added to the filter tank 11 through the top of the cover plate 14. The drive motor is started, driving the pulverizing structure 16 to pulverize the medicine. The pulverized medicine that meets the standards passes through the sieve of the filter tank 11 and falls into the mixing tank 2 through the feed pipe 17. The medicine that is not pulverized continues to remain in the filter tank 11 for further pulverization. During the pulverization process, the dual-shaft motor 25 is started simultaneously, driving the drive shaft 57 and the stirring rod 23 to rotate simultaneously. The drive shaft 57 drives the outer ring 53 of the feed pipe 17 to rotate through the meshing transmission of large and small gears. 53 then drives the outer circular plate 54 to rotate. The four wedges 55 at the top of the circular plate 54 rotate with the circular plate 54 and periodically contact the roller 52 at the bottom of the moving rod 51. The inclined surface of the wedge 55 pushes the roller 52 to rise, driving the moving rod 51 and the fixed block 50 and filter barrel 11 to move upward. When the roller 52 disengages from the wedge 55, the spring 2 58 outside the moving rod 51 contracts, pulling the filter barrel 11 to return to its original position. This process is repeated to achieve continuous shaking of the filter barrel 11 and prevent the crushed medicine particles from clogging the screen of the filter barrel 11. After all the medicines are crushed, they enter the mixing tank 2. Solvent is added into the mixing tank 2 through the feeding pipe at the top of the cover plate 21. Then, the rotation of the stirring rod 23 fully mixes and dissolves the medicine particles and the solvent (liquid) to form a uniform medicine solution. After the mixing is completed, the control valve is opened to discharge the mixed medicine from the mixing tank 2 for the next process.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
