Technical Field
[0001] This utility model relates to the field of Artemisia argyi processing technology, and in particular to a machine for separating Artemisia argyi stems and leaves. Background Technology
[0002] Artemisia argyi, a specialty of Qichun County, Hubei Province, is a Chinese National Geographical Indication product. The plant is tall, reaching 150-250 cm in height, and has a strong aroma. Its leaves are thick and papery, densely covered with hairs; the middle leaves are pinnately shallowly lobed, while the upper leaves are usually unlobed, elliptical or oblong, reaching a length of 7-8 cm and a width of 1.5 cm. When rubbed, the leaves often resemble cotton wool. Medicinally, it is warm, bitter, pungent, and slightly sweet in nature. The volatile oil of Artemisia argyi contains ethyl acetate, 1,8-cineole, camphene hydrote, camphor, borneol, and thujone. Pharmacological analysis shows that the volatile oil has inhibitory effects on various molds, cocci, and bacilli, and also has antiasthmatic and antitussive effects.
[0003] The main useful component of Artemisia argyi is its leaves. Therefore, after harvesting, the stems and leaves need to be separated before the leaves are collected. Currently, existing stem-and-leaf separators (i.e., defoliators) lack a sieving component for the leaves after separation. Since Artemisia argyi undergoes no pre-treatment during stem-and-leaf separation, it contains many impurities. Without sieving to remove impurities, the leaf quality is poor. Furthermore, existing stem-and-leaf separators generate significant dust during the feeding stage, affecting the health of workers. Therefore, this invention proposes an Artemisia argyi stem-and-leaf separator to address the shortcomings of existing technologies. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a separator for Artemisia argyi stems and leaves. The separator uses a reciprocating sliding blade screening and impurity removal mechanism to separate the leaves, effectively removing impurities from the leaves. The dust is removed during the feeding process by a dust extraction fan of the feeding and dust removal mechanism. After the dust is filtered through the first and second filter plates, clean air is discharged.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A stem and leaf separator for Artemisia argyi includes a frame, a separator housing, a leaf screening and impurity removal mechanism, and a feeding and dust removal mechanism.

A leaf discharge plate is located below the opening at the bottom of the separator housing. A leaf screening and impurity removal mechanism is located below the leaf discharge plate. The leaf screening and impurity removal mechanism is slidably mounted to the frame.
[0007] A further improvement is that the blade discharge plate is inclined, and the inclination angle of the blade discharge plate is 40-50°.
[0008] A further improvement is made in that: the feeding dust removal mechanism includes a dust suction pipe, a dust suction fan, a first filter plate, and a second filter plate; an installation chamber is provided above the inside of the feeding shell; a dust suction pipe is provided on one side wall of the installation chamber; multiple sets of dust suction pipes are provided, with one end of each set of dust suction pipes leading into the inside of the feeding shell; a first filter plate and a second filter plate are provided above the inside of the installation chamber; a dust suction fan is installed on the top of the feeding shell; and the input end of the dust suction fan is located above the second filter plate.
[0009] A further improvement is that a dust drawer is slidably provided below the interior of the mounting chamber, and a slot adapted to the dust drawer is provided on the front side wall of the feed shell.
[0010] A further improvement is made in that: the blade screening and impurity removal mechanism includes a screening frame, a discharge screen plate, and a tilting control component. The bottom of the screening frame is provided with a discharge screen plate, one end of which is hinged to one side of the bottom of the screening frame.

[0011] A further improvement is that the tilt control assembly includes a tilt control cylinder, which is hinged to the rotation groove, and the output end of the tilt control cylinder is hinged to the inside of the mounting groove.
[0012] The beneficial effects of this utility model are as follows: This utility model sets an inclined blade discharge plate below the opening structure at the bottom of the separator casing, and then sets a blade screening and impurity removal mechanism below the blade discharge plate. The blade screening and impurity removal mechanism is slidably installed with the frame. The blades can be screened and separated by reciprocating sliding blade screening and impurity removal mechanism, so as to fully screen out the impurities contained in the blades.
[0013] By installing a feeding dust removal mechanism inside the upper part of the feeding shell, the dust in the feeding process can be sucked away by the dust removal fan of the feeding dust removal mechanism. After the dust is filtered by the first filter plate and the second filter plate, clean air is discharged, thereby ensuring that the feeding port of the feeding shell is not affected by large amounts of dust and thus the health of the operators.

A leaf discharge plate 10 is provided below the opening at the bottom of the separator housing 2. The leaf screening and impurity removal mechanism 3 is provided below the leaf discharge plate 10. The leaf screening and impurity removal mechanism 3 is slidably installed with the frame 1.
[0019] When using the Artemisia argyi stem and leaf separator of this utility model, the tail end of the Artemisia argyi is inserted into the feed shell 5, and then the feed transmission roller 7 will transfer the Artemisia argyi into the separator shell 2. Then, the stem and leaf are separated by the leaf separation cutter roller 8. The leaf is adjusted through the opening at the bottom of the separator shell 2 and then discharged through the leaf discharge plate 10 into the leaf screening and impurity removal mechanism 3. Through reciprocating sliding, the impurities in the leaf screening and impurity removal mechanism 3 are screened out.
[0020] The blade discharge plate 10 is inclined at an angle of 45°. The inclined blade discharge plate 10 facilitates the rapid discharge of Artemisia argyi leaves, allowing them to fully enter the blade screening and impurity removal mechanism 3.
[0021] The feeding dust removal mechanism 4 includes a suction pipe 401, a suction fan 402, a first filter plate 403, and a second filter plate 404. An installation chamber 501 is located above the inside of the feeding shell 5. Multiple sets of suction pipes 401 are installed on one side wall of the installation chamber 501, with one end leading into the inside of the feeding shell 5.

The suction fan 402 is installed on the top of the feeding shell 5, with its input end located above the second filter plate 404. During the feeding stage, when the Artemisia argyi is fed into the feeding shell 5, the suction fan 402 is activated to draw dust generated during the feeding process into the installation chamber 501 through the suction pipe 401. The dust is then filtered by the first filter plate 403 and the second filter plate 404 before being discharged.
[0022] A dust drawer 11 is slidably disposed inside the lower part of the installation chamber 501, and a groove adapted to the dust drawer 11 is provided on the front side wall of the feed shell 5.

The tilting control assembly includes a tilting control cylinder 306, which is hinged to the rotating groove 305. The output end of the tilting control cylinder 306 is hinged to the interior of the mounting groove 304. After being separated, the Artemisia argyi leaves enter the screening frame 301 and are screened by the discharge screen 302. Screening can be achieved by reciprocating the screening frame 301 which is slidably connected to the frame 1. When it is necessary to pour out the Artemisia argyi leaves, the tilting control cylinder 306 is extended to drive the discharge screen 302 to flip and tilt, thereby realizing the discharge. The leaves can be collected by the collection box.
[0024] This invention features an inclined blade discharge plate 10 located below the opening structure at the bottom of the separator casing 2, and a blade screening and impurity removal mechanism 3 located below the blade discharge plate 10. The blade screening and impurity removal mechanism 3 is slidably installed with the frame 1. The blades can be screened and separated by the reciprocating sliding blade screening and impurity removal mechanism 3, effectively removing impurities contained in the blades. By setting a feeding dust removal mechanism 4 above the inside of the feeding casing 5, the dust can be sucked away by the dust suction fan 402 of the feeding dust removal mechanism 4. After the dust is filtered by the first filter plate 403 and the second filter plate 404, clean air is discharged, thus ensuring that the feed inlet of the feeding casing 5 is not affected by excessive dust, which could harm the health of the operators.
