[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Reference Figures 1-6 A pharmaceutical drug pulverization and preparation device includes a supporting base plate 1, a pulverizing barrel 2 fixed to one end of the top of the supporting base plate 1, which allows the drug to be pulverized inside the pulverizing barrel 2, and a collection box 3 slidably connected to the other end of the top of the supporting base plate 1, so that when the collection box 3 is inside the supporting base plate 1, one end of the collection box 3 is in contact with the pulverizing barrel 2, which allows the pulverized drug inside the pulverizing barrel 2 to enter the collection box 3 for storage. A closing cover 5 is provided inside the top of the pulverizing barrel 2, which allows the pulverized drug to be splashed through the closing cover 5.

[0033] Preferably, a handle 4 is fixed to the top of the collection box 3, so that the collection box 3 can be moved up and down by the handle 4.

[0034] In other embodiments, the collection box 3 is connected by upper and lower threads, and a filter plate is fixed between the upper and lower layers, so that the pulverized medicine discharged from the pulverizing barrel 2 can be filtered again.

[0035] In this embodiment, the closed cover 5 is slidably connected to the inside of the top of the crushing barrel 2. In other embodiments, the inside of the top of the crushing barrel 2 and the closed cover 5 may also be threadedly connected.

[0036] A pulverizing mechanism is installed inside the top of the pulverizing barrel 2 for pulverizing drugs entering the pulverizing barrel 2. The pulverizing mechanism includes a first pulverizer 6, a second pulverizer 7, a guide fluid 8, a rotating rod 9, a first pulverizing block 12, and a second pulverizing block 13. The first pulverizer 6 is fixed inside the pulverizing barrel 2. A pulverizing groove is opened inside the top of the first pulverizer 6. The second pulverizer 7 is arranged inside the pulverizing groove, and the top of the second pulverizer 7 is lower than the top of the pulverizing groove on the first pulverizer 6, so that the drug can enter the gap between the top of the second pulverizer 7 and the pulverizing groove through the gap between the top of the second pulverizer 7 and the pulverizing groove. The shape of the pulverizing groove is an inverted frustum, and the shape of the second pulverizer 7 is also an inverted frustum. There is a gap between the second pulverizer 7 and the pulverizing groove, so that the drug can enter the gap between the second pulverizer 7 and the pulverizing groove for pulverization. A rotating rod 9 is arranged inside the first pulverizer 6. The top of the rotating rod 9 is fixed to the second pulverizer 7, so that the rotation of the rotating rod 9 drives the second pulverizer 7 to rotate.

[0037] In this embodiment, both the first crushing component 6 and the second crushing component 7 can be in the shape of a frustum or a rectangle.

[0038] The inner side of the grinding chamber is uniformly fixed with first grinding blocks 12, and the bottom of the outer side of the second grinding component 7 is uniformly fixed with second grinding blocks 13. The first grinding blocks 12 and the second grinding blocks 13 are fixed alternately, so that the rotation of the second grinding component 7 inside the grinding chamber, through the alternation of the first grinding blocks 12 and the second grinding blocks 13, pulverizes the drug. The top of the second grinding component 7 is fixed with a guide fluid 8, which is frustoconical in shape, so that the drug enters the diversion through the guide fluid 8 and enters between the second grinding component 7 and the first grinding component 6, and prevents the drug from accumulating on the top of the second grinding component 7. The inside of the first grinding component 6 and at the bottom of the grinding chamber, through holes 11 are uniformly distributed, and the through holes 11 are staggered with the first grinding blocks 12. Thus, the through holes 11 are evenly distributed in multiple annular shapes inside the first grinding component 6, allowing the pulverized drug to descend through the first grinding blocks 12.

[0039] In other embodiments, the diameter of the plurality of through holes 11 may also gradually decrease from the outside to the inside; thereby allowing the drug to fall off during the component crushing process.

[0040] A flow guiding mechanism is installed inside the pulverizing barrel 2 and at the bottom of the pulverizing mechanism. The flow guiding mechanism includes a flow guiding plate 15, a flow guiding sleeve 16, a collecting cylinder 17, a flow guiding channel 18, and a scraper 19. A flow guiding cylinder 14 is fixed inside the pulverizing barrel 2 and at the bottom of the first pulverizing component 6. The top of the flow guiding cylinder 14 is in contact with the first pulverizing component 6. A flow guiding plate 15 is fixed to one end inside the flow guiding cylinder 14. An inclined surface is provided on the top of the flow guiding plate 15 so that the medicine falling on the top of the flow guiding plate 15 slides to the other end inside the flow guiding cylinder 14 through the inclined surface. A flow guiding sleeve 16 is fixed to one end of the flow guiding plate 15. The shape of the flow guiding sleeve 16 is an inverted frustum. The inside of the flow guiding sleeve 16 is rotatably connected to the rotating rod 9 so that the rotation of the rotating rod 9 will not drive the flow guiding sleeve 16 to rotate. At the same time, the inverted frustum shape of the flow guiding sleeve 16 allows the medicine on the outside to slide and fall.

[0041] Inside the pulverizing barrel 2 and at the bottom of the guide tube 14, a collecting cylinder 17 is fixed. The top of the collecting cylinder 17 is in contact with the guide tube 14. Inside the collecting cylinder 17 and at the bottom of the guide plate 15, a rectangular groove is formed. At the bottom of the collecting cylinder 17 and at the position corresponding to the rectangular groove, a guide channel 18 is fixed, so that the pulverized medicine inside the collecting cylinder 17 falls into the guide channel 18 through the rectangular groove and enters the outer collecting box 3 through the guide channel 18. One end of the rotating rod 9 and at the inner side of the top of the collecting cylinder 17 is fixed with a scraper 19, so that the rotation of the rotating rod 9 drives the scraper 19 to rotate synchronously. The outer side of the scraper 19 is in contact with the collecting cylinder 17, so that the rotation of the scraper 19 pushes the pulverized medicine inside the collecting cylinder 17 into the rectangular groove. Inside the pulverizing barrel 2 and at the bottom of the collecting cylinder 17, a pulverizing drive motor 10 is fixed. The output end of the pulverizing drive motor 10 is connected to the rotating rod 9, so that the operation of the pulverizing drive motor 10 drives the rotating rod 9 to rotate.

[0042] In other embodiments, brushes can be evenly distributed and fixed on the outside of the scraper 19, so that the rotation of the scraper 19 can clean the pulverized drug inside the collection cylinder 17 into the rectangular groove through the brushes.

[0043] The usage process of the pharmaceutical pulverizing and preparation device provided by this utility model is as follows: During use, the collection box 3 is slidably installed inside the support base plate 1 from top to bottom, with one end of the collection box 3 in contact with the pulverizing barrel 2. Then, the closed cover 5 at the top of the pulverizing barrel 2 is removed, and the drug to be pulverized is placed inside the top of the pulverizing barrel 2. After being diverted by the guide fluid 8, the drug enters the gap between the second pulverizing element 7 and the pulverizing tank. At this time, the operation of the pulverizing drive motor 10 drives the rotating rod 9 to rotate, and the rotation of the rotating rod 9 drives the second pulverizing element 7... The pulverizer 7 rotates, causing the second pulverizer 7 to rotate, which in turn drives the second pulverizer block 13 to rotate. The incoming drug is pulverized by the alternation of the second pulverizer block 13 and the first pulverizer block 12. The pulverized drug falls through the through hole 11 and then enters one end of the collection cylinder 17 through the inclined guide plate 15. The rotation of the rotating rod 9 drives the scraper 19 to rotate at the same time. The rotation of the scraper 19 pushes the pulverized drug inside the collection cylinder 17 onto the rectangular groove, and then enters the collection box 3 through the guide channel 18.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
