Description

Technical Field

[0001] This utility model relates to the technical field of equipment for producing Chinese medicinal materials, and in particular to a drum structure for a dust removal machine for Chinese medicinal materials. Background Technology

[0002] In drum-type Chinese medicinal herb cleaning and dust removal equipment, the drum is generally cylindrical. Taking a drum-type Chinese medicinal herb cleaning device disclosed in patent document CN221620204U and a drum screening machine and a Chinese herbal medicine dust removal and impurity removal system containing the drum screening machine disclosed in CN101786079B as examples, multiple inclined guide plates are set on the inner side wall of the drum to realize the regular forward movement of the medicinal materials, which are finally discharged from the discharge port at the right end. The inclination angle of the guide plates directly determines the length of time the medicinal materials stay in the drum. In the above-mentioned prior art, the inclination angle of the guide plates is fixed. Therefore, when the drum speed is constant, the cleaning time of the Chinese medicinal materials in the drum cannot be adjusted. However, the total amount of dirt and impurities adhering to different batches of Chinese medicinal materials is different, resulting in incomplete cleaning or over-cleaning. In addition, traditional drums are just simple cylindrical tubes. During the tumbling of the drum, the Chinese medicinal materials are concentrated in the lower part of the drum, resulting in insufficient tumbling and low dust removal efficiency.

[0003] To address the aforementioned issues, a drum structure for a dust collector for Chinese medicinal herbs is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a drum structure for a Chinese herbal medicine dust collector, which effectively solves the problems of insufficient tumbling of Chinese herbal medicines, low dust removal efficiency, and inability to adjust the cleaning time of Chinese herbal medicines in existing drum dust collectors.

[0005] The technical solution includes a drum in a medicinal herb cleaning and dust removal device. The drum has an opening at its left end, and multiple arc structures are set on the side wall of the drum, making the cross-section of the drum shaped like a plum blossom. Each arc structure contains a spiral blade parallel to the drum. There is an annular plate on the left side of the drum. The right end of the spiral blade is fixed to the side wall of the drum, and the left end of the spiral blade is fixed to the annular plate. Multiple screws are fixed on the annular plate, and limit nuts are screwed on the screws. The limit nuts and screws can control the size of the gap between the annular plate and the left end of the drum.

[0006] Preferably, the outer edge of the helical blade contacts the arc structure on the side wall of the drum.

[0007] Preferably, each screw has at least two limiting nuts, a protrusion is provided on the outer side of the left end of the roller, the screw passes through the protrusion, and the multiple limiting nuts can clamp the protrusion.

[0008] This invention features a clever structure that elevates medicinal herbs to a considerable height before allowing them to fall, thus fully exposing the soil and impurities on the herbs and facilitating dust removal. Simultaneously, the extensibility of the spiral blades allows for adjustment of the time the herbs remain in the drum for cleaning, flexibly adapting to the dust removal requirements of herbs with varying impurity content.

[0011] Figure 3 This is an exploded view of the present invention. Detailed Implementation

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 The present invention includes a roller 1 in a medicinal herb cleaning and dust removal device. The roller 1 is open at the left end, and multiple arc structures are provided on the side wall of the roller 1, making the cross-section of the roller 1 plum blossom-shaped. Each arc structure contains a spiral blade 2 parallel to the roller 1. There is an annular plate 3 on the left side of the roller 1. The right end of the spiral blade 2 is fixed to the side wall of the roller 1, and the left end of the spiral blade 2 is fixed to the annular plate 3. Multiple screws 4 are fixed on the annular plate 3, and limit nuts 5 are screwed on the screws 4. The limit nuts 5 and the screws 4 can control the size of the gap between the annular plate 3 and the left end of the roller 1.

[0014] The outer edge of the spiral blade 2 is in contact with the arc structure on the side wall of the roller 1.

[0015] In order to better limit the position of the annular plate 3, each screw 4 has at least two limiting nuts 5, and a protrusion is provided on the outer side of the left end of the roller 1. The screw 4 passes through the protrusion, and the multiple limiting nuts 5 can clamp the protrusion.

[0016] It is worth noting that, in this scheme, similar to the traditional roller 1, the feed inlet is at the right end of the roller 1, the roller 1 is made of a screen plate, and the impurities suspended inside the roller 1 can be sucked away by the dust collector in time; unlike the traditional roller 1, in this scheme, the gap between the annular plate 3 and the left end of the roller 1 is the discharge port.

[0017] When in use, the medicinal materials are poured in from the right end of the roller 1. As the roller 1 rotates, its arc-shaped structure allows it to lift the medicinal materials to a high height and then throw them downwards, so that impurities can be removed from the medicinal materials as quickly as possible. During the throwing process, the spiral blades 2 replace the traditional guide plates, causing the medicinal materials to be continuously moved to the left. Finally, after a period of tumbling, the medicinal materials fall from the left end of the roller 1, completing the dust removal operation.

[0018] When it is necessary to adjust the cleaning and dust removal time of the medicine, the extension and retraction of the spiral blades 2 can be achieved by controlling the distance between the annular plate 3 and the drum 1. During the extension and retraction of the spiral blades 2, the lead also changes accordingly, and the speed of the axial displacement of the medicine in the drum 1 also changes, thereby adjusting the cleaning and dust removal time of the medicine in the drum 1. This method is suitable for dust removal of different batches and types of medicines.

[0019] This invention has a clever structure that can lift Chinese medicinal materials to a considerable height before they fall, fully exposing the soil and impurities in the medicinal materials and facilitating dust removal operations. At the same time, by utilizing the extensibility of the spiral blades 2, the residence time of the medicinal materials in the drum 1 can be adjusted, flexibly adapting to the dust removal requirements of medicinal materials with different impurity contents.
