The first screw passes through the first scraper and is threadedly driven by the first scraper. The second screw passes through the second scraper and is threadedly driven by the second scraper. The base is provided with a second drive motor that drives the second screw.

[0011] A further improvement is that the base is provided with a clearance notch for the sliding drawer's sealing plate to slide into.

[0012] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0013] With a simple structure, it prevents powder from flying around during crushing. When crushing medicinal materials, the sliding drawer seals the feed inlet, while the hinged plate seals the discharge channel. This prevents the herbs from escaping from the crushing chamber, thus eliminating dust and protecting the health of workers. The sliding drawer 7 also greatly facilitates automatic feeding of herbs; simply place the herbs into the drawer for automatic feeding, which is both convenient and safe. Attached Figure Description

[0015] Figure 2 This is an enlarged structural schematic diagram of embodiment A of this utility model. Detailed Implementation

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] refer to Figure 1-2 The present invention discloses a pharmaceutical pulverizer, comprising a base 1 and a pulverizing chamber 2 disposed on the base 1. A crushing wheel 3 is rotatably disposed within the pulverizing chamber 2. A feeding seat 5 is disposed at the upper end of the base 1. A feeding channel 6 communicating with the pulverizing chamber 2 is disposed on the feeding seat 5. A feeding inlet communicating with the feeding channel 6 is disposed on the side of the feeding seat 5. A sliding drawer 7 for placing medicinal materials is slidably disposed at the feeding inlet. A friction wheel 11 is disposed on the feeding seat 5 to drive the sliding drawer 7 to slide. The friction wheel 11 is rotatably disposed on the base 1 and located at the feeding inlet. A friction channel 10 is horizontally disposed at the bottom of the sliding drawer 7. The friction wheel 11 is located inside the friction channel 10 and resists the inner wall of the friction channel 10. After the friction wheel 11 rotates, it drives the sliding drawer 7 to slide. The base 1 is equipped with a rotating motor that drives the friction wheel 11 to rotate. The sliding drawer 7 is equipped with a push plate 9 that pushes the medicinal materials into the feeding channel 6. The outer end of the sliding drawer 7 is equipped with a push cylinder 8. The inside of the sliding drawer 7 is equipped with a push plate 9. The push cylinder 8 is connected to the push plate 9. The lower end of the base 1 is provided with a conical discharge channel 4. The base 1 is equipped with an opening and closing device for opening and closing the discharge channel 4 at the position of the discharge channel 4.

[0018] Specifically, the opening and closing device includes an opening and closing plate 16. The base 1 is located at the discharge channel 4 and has an opening and closing channel 18 opened laterally. The opening and closing plate 16 is slidably disposed in the opening and closing channel 18. A rotating screw 17 is rotatably disposed in the opening and closing channel 18. The rotating screw 17 passes through the opening and closing plate 16 and is threadedly driven by the opening and closing plate 16. The opening and closing plate 16 and the opening and closing channel 18 are rectangular. The opening and closing plate 16 is larger than the discharge channel 4 and seals the discharge channel 4. A first drive motor for driving the rotating screw 17 to rotate is disposed in the opening and closing channel 18.

[0019] In operation, when the medicinal material blocks need to be crushed, the first drive motor operates, driving the rotating screw 17 to slide the opening and closing plate 16, thereby sealing the discharge channel 4. The medicinal material blocks are then placed into the sliding drawer 7. At this time, the rotating motor operates, driving the friction wheel 11 to rotate. The friction wheel 11 abuts against the inner wall of the friction channel 10, thereby causing the sliding drawer 7 to slide into the feed inlet and seal it. Then, the cylinder 8 is pushed, causing the push plate 9 to slide, pushing the medicinal material blocks into the feed channel 6, where they fall onto the crushing wheel for crushing. After crushing, they fall to the bottom of the crushing chamber 2. At this point, the first drive motor operates again, driving the rotating screw 17 to reverse, causing the opening and closing plate 16 to return to its original position. After the opening and closing plate 16 returns to its original position, the discharge channel 4 is opened, and the crushed medicinal material exits from the discharge channel 4. In this way, by sealing the inlet and outlet channels 4, the medicinal materials will not escape from the crushing chamber 2 during crushing, thus preventing the generation of dust and avoiding any impact on the health of the workers. Furthermore, the sliding drawer 7 greatly facilitates the automatic feeding of medicinal materials by the workers; simply placing the materials into the drawer enables automatic feeding, which is both convenient and safe.

[0020] To facilitate the removal of medicinal materials from the bottom to the discharge channel 4, the system includes a first scraper 14 and a second scraper 15, a first screw 12, and a second screw 13 with the opposite thread to the first screw 12. The first scraper 14 and the second scraper 15 are slidably disposed at the bottom of the feed hopper, with their ends resisting the inner wall of the crushing channel. The first scraper 14 and the second scraper 15 abut against the bottom of the feed hopper. The first screw 12 and the second screw 13 have the same thread. The two ends of the first screw 12 and the second screw 13 are rotatably disposed at the bottom of the crushing hopper 2. The first screw 12 passes through the first scraper 14 and is threadedly driven by the first scraper 14. The second screw 13 passes through the second scraper 15 and is threadedly driven by the second scraper 15. The base 1 is equipped with a second drive motor that drives the second screw 13. In use, the rotation of the first screw 12 and the second screw 13 causes the first scraper 14 and the second scraper 15 to slide towards each other, thereby sliding towards the discharge channel 4. This scrapes the medicinal materials at the bottom of the powder hopper to the discharge channel 4 for discharge, thus better cleaning out the powder at the bottom of the powder hopper and greatly facilitating the operation of the staff.

[0021] In order to better seal the feed inlet, the base 1 is provided with a clearance notch for the sealing plate of the sliding drawer 7 to slide into.
