[0026] This application proposes a drum-type herbal medicine separation device, such as... Figures 1 to 3As shown, the device includes: a mounting frame 100, a drum screen 200, an anti-clogging component 300, a first support 410, and a second support 430. The drum screen 200 is rotatably mounted on the mounting frame 100. The drum has a cavity with an opening on one side. The first support 410 is fixedly mounted on the mounting frame 100 and located at the opening of the drum. The second support 430 is disposed within the cavity of the drum screen 200. One end of the anti-clogging component 300 is connected to the first support 410, and the other end of the anti-clogging component 300 extends into the drum screen 200. The housing of the 0 is connected to the second support part 430; the anti-clogging component 300 includes: support arm 310, cleaning brush 320 and connector 330; one end of support arm 310 is connected to the second support part 430, and the other end of support arm 310 is connected to the first support part 410; the cleaning brush 320 is detachably mounted on support arm 310 through connector 330, and the bristles of cleaning brush 320 are in contact with the inside of drum screen 200, which is suitable for cleaning the inner wall of drum screen 200 when drum screen 200 rotates.
[0027] It should be noted that the mounting frame 100 provides a stable mounting foundation for the entire equipment. The drum screen 200 is rotatably mounted on the mounting frame 100 and can rotate around its own axis. The rotation of the drum screen 200 allows the herbs to tumble and stir fully within the cavity, increasing the contact opportunity between the herbs and the sieve holes, and improving the uniformity and thoroughness of the separation of fine powder and qualified product. The drum wall of the drum screen 200 has a structure with a screen mesh of a specific aperture, which can be selected according to the specific requirements of herb separation to achieve the separation of qualified herb and fine powder. The first support part 410 is set on the mounting frame 100 and adjacent to the opening of the drum screen 200. The first support part 410 is used to provide stable positioning support for the anti-clogging component 300 without affecting the normal rotation of the drum screen 200. The second support part 430 is used to provide stable support for the end of the anti-clogging component 300 away from the first support part 410, so that the anti-clogging component 300 maintains a stable position inside the drum screen 200. The first support part 410 and the second support part 430... Working in tandem, the anti-clogging component 300 is fixedly installed inside the drum screen 200, enabling the cleaning brush 320 of the anti-clogging component 300 to accurately contact and clean the inner wall of the drum screen 200. The support arm 310 provides a stable mounting base for the cleaning brush 320. Both ends of the support arm 310 are connected to the first support part 410 and the second support part 430 respectively, ensuring stable support for the cleaning brush 320 to clean the inner wall of the drum screen 200 during rotation. The length of the arm is along... The axial extension of the drum screen 200 ensures that the cleaning brush 320 can cover the area of the inner wall of the drum screen 200 that needs to be cleaned. The cleaning brush 320 is detachably mounted on the support arm 310 via the connector 330 and is in contact with the inner wall of the drum screen 200. When the drum screen 200 rotates, the cleaning brush 320 can clean the inner wall of the drum screen 200 to prevent fine powder from adhering and accumulating and clogging the screen. The connector 330 is suitable for detachably mounting the cleaning brush 320 on the support arm 310, making it convenient to replace the cleaning brush 320 after it wears out.
[0028] As the drum screen 200 rotates around its own axis, the herbs tumble inside. Fine powder falls through the screen holes of the drum screen 200, while qualified products remain inside, thus separating qualified herbs from fine powder. At the same time, because the cleaning brush 320 of the anti-clogging component 300 contacts the inner wall of the drum screen 200, as the drum screen 200 rotates, the cleaning brush 320, driven by the support arm 310, continuously cleans the inner wall of the drum screen 200. Fine powder adhering to the screen surface is brushed off by the cleaning brush 320, preventing fine powder from accumulating and clogging the screen holes, ensuring the screen's permeability, and enabling the screening work to continue efficiently. When the cleaning brush 320 wears out after a period of use and affects the cleaning effect, it can be easily removed from the support arm 310 for replacement by disassembling the connector 330. This ensures that the anti-clogging component 300 always maintains a good working condition. By setting the anti-clogging component 300, this application utilizes the mechanical cleaning principle. The cleaning brush 320 will clean the inner wall of the drum screen 200 as it rotates, eliminating the need for manual tapping of the screen, greatly reducing labor input and production costs. The cleaning brush 320 continuously cleans the inner wall of the drum screen 200, effectively preventing screen clogging, ensuring the continuity and efficiency of the screening process, and improving the efficiency of herbal separation.
[0029] Furthermore, the main body of the support arm 310 is a rectangular plate structure. One end of the support arm 310 is connected to the first support part 410, and the other end of the support arm 310 is fixedly connected to the second support part 430 by welding. One side of the cleaning brush 320 is attached to the side wall of the support arm 310, and the bristles of the cleaning brush 320 are set towards the inner wall of the drum screen 200.
[0030] Furthermore, the drum screen 200 can be made by precisely opening an array of screen holes on the cylindrical drum body through mechanical processing. This drum screen 200 has a simple structure design, is sturdy and durable, and the screen holes are not easily deformed.
[0031] Furthermore, the drum screen 200 can also consist of two parts: a cylindrical frame and a mesh screen. The mesh screen is fitted over the cylindrical frame, and its fine mesh allows for the precise sieving of herbs. The material and mesh size of the mesh screen can be flexibly selected according to the characteristics of different herbs and sieving requirements.
[0032] In one possible implementation, the connector 330 includes a first bolt and a second nut. Mounting holes are provided on both the support arm 310 and the cleaning brush 320. The mounting holes are arranged opposite to each other and match the connector 330. The first bolt passes through the support arm 310 and is threadedly connected to the first nut through the mounting hole on the cleaning brush 320. By tightening the first nut, the first bolt and the first nut are matched to provide sufficient clamping force, thereby securely mounting the cleaning brush 320 on the support arm 310. The detachable connection method makes maintenance and replacement of the cleaning brush 320 more convenient and reduces the maintenance cost of the equipment.
[0033] In one possible implementation, there are two or more connectors 330, spaced apart along the length of the support arm 310. It should be noted that the multiple spaced connectors 330 provide multiple support points for the cleaning brush 320 on the support arm 310, ensuring a stable connection between the cleaning brush 320 and the support arm 310. This provides sufficient support for the cleaning brush 320 during operation, ensuring that the bristles of the cleaning brush 320 adhere to the inner wall of the drum screen 200 when in contact with it. This allows for a more comprehensive and effective cleaning of herbs and impurities on the inner wall of the drum screen 200, preventing the cleaning brush 320 from tilting due to insufficient support, thus avoiding situations where some areas are not cleaned and improving the anti-clogging effect.
[0034] Furthermore, two or more connectors 330 are equidistantly arranged along the length of the support arm 310. The equidistantly arranged connectors 330 ensure that the cleaning brush 320 receives uniform support during operation, ensuring that when the cleaning brush 320 contacts the inner wall of the drum screen 200, the bristles of the entire cleaning brush 320 can evenly adhere to the inner wall of the drum screen 200.
[0035] In one possible implementation, a mounting base 420 is provided on the first support portion 410; one end of the support arm 310 is detachably mounted on the mounting base 420. It should be noted that the mounting base 420 includes a first hinge plate and a second hinge plate disposed opposite to each other. Both the first and second hinge plates are fixedly mounted on the first support portion 410, and both the surfaces of the first and second hinge plates are vertically arranged, with a preset distance between them. One end of the support arm 310 is positioned between the first and second hinge plates. A second bolt passes sequentially through the first hinge plate, the support arm 310, and the second hinge plate before being threadedly connected to a second nut. By tightening the second nut, the second bolt and the second nut are mutually engaged to provide sufficient clamping force, thereby achieving a detachable connection between the support arm 310 and the mounting base 420.
[0036] In one possible implementation, the drum screen 200 is equipped with a hinge shaft 440 located on the axis of the drum screen 200. One end of the second support part 430 is hinged to the hinge shaft 440, and the other end of the second support part 430 is connected to the support arm 310. It should be noted that the hinge shaft 440 is fixedly installed inside the drum screen 200, and the length direction of the hinge shaft 440 coincides with the axial direction of the drum screen 200. One end of the second support part 430 is sleeved on the hinge shaft 440. The connection between the second support part 430 and the hinge shaft 440 ensures that the second support part 430 does not rotate with the drum screen 200. This allows the cleaning brush 320 to remain relatively stationary when the drum screen 200 rotates, ensuring that the cleaning brush 320 always remains in contact with the inner wall of the drum screen 200 in a specific position. This avoids blind spots or repeated cleaning caused by the rotation of the cleaning brush 320, improving cleaning efficiency and effectiveness, and better preventing clogging of the drum screen 200.
[0037] In one possible implementation, a purlin 210 is also included; the purlin 210 is fixedly disposed on the inner wall of the drum screen 200 and extends along the length of the drum screen 200.
[0038] It should be noted that the main body of the purlin 210 is columnar. The purlin 210 is fixed to the inner wall of the drum screen 200 by welding. When the drum screen 200 rotates, the cleaning brush 320 comes into contact with the purlin 210 on the inner wall of the drum screen 200. The cleaning brush 320, due to its own flexibility, will generate a certain pressure on the surface of the purlin 210. The purlin 210 can scrape off the fine powder, herbal residue, etc. attached to the cleaning brush 320. Through this scraping action, the cleaning brush 320 is kept clean, avoiding the impact of fine powder on the cleaning effect of the cleaning brush 320. This effectively prevents the cleaning effect on the inner wall of the drum screen 200 from being reduced due to fine powder attached to the cleaning brush 320, and further improves the cleaning effect.
[0039] In one possible implementation, there are two or more purlins 210; the two or more purlins 210 are equidistantly arranged along the circumference of the drum screen 200. It should be noted that the equidistantly distributed purlins 210 can fully cover the circumference of the drum screen 200, so that each part of the cleaning brush 320 can regularly contact the purlins 210 during the rotation of the drum screen 200, thereby ensuring that all parts of the cleaning brush 320 are cleaned in a timely and uniform manner.
[0040] Preferably, there are fifteen purlins 210, which are equidistantly arranged along the circumference of the drum screen 200.
[0041] In one possible implementation, a receiving port 500 is also included; the receiving port 500 is connected to the first support part 410, and the receiving port 500 is inclined. It should be noted that the discharge port is suitable for collecting qualified products falling from the drum screen 200. The receiving port 500 is fixedly connected to the first support part 410 by welding. One end of the receiving port 500 is adjacent to the drum screen 200 and located below the drum screen 200. Qualified products separated in the drum screen 200 fall from the opening of the drum screen 200 into the receiving port 500. The inclined receiving port 500 can guide the flow of qualified products by gravity. After being screened out of the drum screen 200, the qualified products slide down along the inclined receiving port 500 under the action of gravity, which makes it easy to collect the qualified products in a designated location, which is beneficial for subsequent further processing or transportation of the qualified products.
[0042] In one possible implementation, the receiving port 500 is configured to gradually narrow from one end near the drum screen 200 to the other end away from the drum screen 200. It should be noted that this gradual narrowing shape guides the qualified products falling from the drum screen 200, causing them to gradually converge at the narrower outlet. This guides the qualified products, causing them to flow in a specific direction, preventing them from scattering, and facilitating accurate collection into specific containers or conveying devices, thus improving the accuracy of the qualified product collection.
[0043] Furthermore, the narrower end of the discharge port is less than 50cm wide, and the smaller receiving port 500 can fit more tightly into the collection container, reducing the leakage of qualified products from the gap between the discharge port and the container during the loading process. This ensures that qualified products can fall into the container more accurately, thereby improving the recovery rate of qualified products.
[0044] In one possible implementation, the drum screen 200 is rotatably mounted on the mounting frame 100 via a transmission mechanism. Specifically, it includes a drive motor 610, a transmission shaft 620, and a transmission belt 630. The drive motor 610 is fixedly mounted on the mounting frame 100 and located on the side of the drum screen 200 away from the opening. The mounting frame 100 is provided with a rotating plate 621, which is also located on the side of the drum screen 200 away from the opening. The transmission shaft 620 is rotatably mounted on the rotating plate 621, with one end of the transmission shaft 620 fixedly connected to the drum screen 200. The length direction of the transmission shaft 620 is aligned with the axis of the drum screen 200. The output shaft of the drive motor 610 is provided with a drive wheel, and the transmission belt 630 is sleeved on the drive wheel and the transmission shaft 620. The drive motor 610 drives the drive wheel to rotate, thereby rotating the transmission shaft 620 and realizing the rotation of the drum screen 200.
[0045] Furthermore, driven wheels 640 are provided on the mounting frame 100, and the two driven wheels 640 are tangentially arranged with the outer wall of the drum screen 200. The driven wheels 640 are located on both sides of the opening of the drum screen 200. The drum screen 200 rotates under the drive of the drive motor 610. Since the driven wheels 640 are tangentially arranged and in close contact with the outer wall of the drum screen 200, the rotational motion of the drum screen 200 is transmitted to the driven wheels 640 through friction, so that the driven wheels 640 rotate with the rotation of the drum screen 200. The driven wheels 640 are suitable for providing support for the drum screen 200, ensuring that the drum screen 200 rotates stably around its axis, thereby ensuring the stable operation of the equipment.
