The user can pull the collection box 4 through the groove 403 part to move the collection box 4 for taking.

[0041] In a further preferred embodiment of the present utility model, as Figure 2 , Figure 3 and Figure 4 shown, the scraping assembly 5 includes a mounting strip 501 fixedly connected to the moving frame 6. A rubber scraping plate 502 is fixedly connected to the lower surface of the mounting strip 501. The rubber scraping plate 502 is located above the first perforated plate 302 near the rectangular strip 301.

[0042] In this embodiment, the mounting strip 501 can limit the mounting position of the rubber scraping plate 502. When the moving frame 6 moves, the mounting strip 501 can drive the rubber scraping plate 502 to move. When the rubber scraping plate 502 moves down and contacts the first perforated plate 302, the traditional Chinese medicine pieces on the first perforated plate 302 can be scraped off by the movement of the first perforated plate 302. And the rubber scraping plate 502 needs to be made of a rubber material with high temperature resistance.

[0043] In a further preferred embodiment of the present utility model, as Figure 2 , Figure 3 and Figure 4 shown, the moving frame 6 includes a moving strip 601 located above the rectangular box 201. Symmetrically fixed connection strips 602 are fixedly connected to the lower surface of the moving strip 601. The symmetrically arranged connection strips 602 are both slidably connected to the inner wall of the rectangular box 201. The symmetrically arranged connection strips 602 respectively penetrate through both ends of the mounting strip 501 and are fixedly connected therebetween. A threaded hole 603 is formed in the moving strip 601 for the through hole. The wing bolt 7 passes through the interior of the threaded hole 603 and is threadedly connected therebetween.

[0044] In this embodiment, the threaded hole 603 can limit the connection position between the moving strip 601 and the wing bolt 7, so that when the user rotates the wing bolt 7, the moving strip 601 can be adjusted to move. When the moving strip 601 moves, it can drive the symmetrically arranged connection strips 602 to move at the same time. The connection strips 602 are fixedly connected to the ends of the mounting strip 501, so that the position of the mounting strip 501 can be adjusted by the movement of the connection strips 602.

[0045] The implementation principle of a traditional Chinese medicine piece steaming device in an embodiment of this application is:

[0046] During use, the operator spreads the Chinese herbal pieces to be steamed on multiple steaming racks 3, then slidably installs the steaming racks 3 into the interior of the steaming box 2. At the same time, a collection box 4 also needs to be installed inside the steaming box 2, with the collection box 4 positioned below the multiple steaming racks 3. Start the steamer 1 to heat the water. The steam after the water is heated rises into the steaming box 2, and the Chinese herbal pieces placed on the steaming racks 3 can be steamed. After the steaming process is completed, the user turns the wing bolt 7 to control the movement of the adjustment moving frame 6, which can synchronously drive the multiple scraping components 5 to move downward and contact the steaming racks 3. The operator pulls the steaming racks 3 out of the steaming box 2. While the steaming racks 3 are being pulled outwards, the scraping components 5 scrape the Chinese herbal pieces on the steaming racks 3, so that the Chinese herbal pieces can directly fall into the interior of the collection box 4 for collection. After the operator pulls out all the multiple steaming racks 3, the collection box 4 can be taken out. When taking the Chinese herbal pieces in this application, the Chinese herbal pieces on the multiple steaming racks 3 are directly scraped into the interior of the collection box 4 by the multiple scraping components 5 respectively and then can be taken out centrally, thus being able to avoid the situation where personnel are scalded when taking the Chinese herbal pieces as much as possible. At the same time, it can also improve the processing efficiency of the Chinese herbal pieces, making this application more conducive to actual use.

[0047] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
