Description

Technical Field

[0001] This utility model relates to the technical field of screening and slag removal, specifically to a processing screening and slag removal mechanism. Background Technology

[0002] Polygonatum is a precious traditional Chinese medicine with the effects of replenishing qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys. As a herb used in both medicine and food, its rhizomes are rich in active ingredients such as polysaccharides, saponins, and flavonoids, and are widely used in medicinal conditioning and health food processing, with market demand showing a continuous upward trend. In the industrial processing of Polygonatum, screening and slag removal is a key pretreatment step—the surface of fresh or minimally processed Polygonatum rhizomes is easily covered with impurities such as mud, sand, and humus. Screening and slag removal devices are usually used to filter Polygonatum to improve its cleanliness.

[0003] Chinese patent CN218591117U discloses a sieving and slag removal device for processing Polygonatum sibiricum, comprising a processing frame, a feeding frame that is fixedly installed on the right side of the top wall of the processing frame and communicates with the interior of the processing frame, a partition plate that is fixedly installed at the center of the interior of the processing frame, a collection drawer that is slidably connected to the left end of the front side wall of the processing frame, multiple connecting hinges that are provided inside the processing frame, a sorting mesh that is rotatably connected to the right side wall of the interior of the processing frame through the connecting hinges, an adjusting frame that is rotatably installed on the top wall of the partition plate through the connecting hinges, an extension spring that is provided inside the adjusting frame, and an extension rod that is slidably connected inside the adjusting frame.

[0004] In the above scheme, the extension rod is pushed by the extension spring inside the adjustment frame, so that the sorting net rotates up and down around the connecting hinge on the sorting net repeatedly, causing the Polygonatum on the top wall of the sorting net to bounce, which facilitates the screening of Polygonatum. However, this scheme has the following disadvantages: the sorting net is set at an angle and has no driving source, so the Polygonatum on its surface tends to accumulate on the right side of the sorting net, and it is impossible to effectively remove impurities from the surface of Polygonatum. Utility Model Content

[0005] The purpose of this invention is to provide a processing, screening, and slag removal mechanism to solve the problem that when the sorting mesh is tilted and has no driving source, the Polygonatum sibiricum on its surface tends to accumulate on the right side of the sorting mesh, making it impossible to effectively remove impurities from the surface of Polygonatum sibiricum.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a processing, screening, and slag removal mechanism, including a mounting plate, which is rotatably disposed within a housing. A drive motor is fixed to the outer left side of the housing, and one end of the output shaft of the drive motor extends into the housing. The mounting plate is fixed to the outer wall of the output shaft of the drive motor. Several receiving grooves are provided on the top and bottom surfaces of the mounting plate. Two L-shaped plates are provided on the inner wall of the housing, and several through holes are provided on the L-shaped plates. Several connecting columns are fixed on the L-shaped plates, and the connecting columns are inserted into the receiving grooves. A spring is connected to the connecting column, and the other end of the spring is connected to the inner bottom surface of the receiving groove. A grid plate is detachably snapped onto the inner wall of the housing, and the L-shaped plates are rotatably disposed in the holes of the grid plate. A protective cover is rotatably connected to the housing via a hinge, and a storage cylinder is rotatably disposed on the protective cover. The storage cylinder is connected to the output end of an external water supply device via a connecting pipe, and several spray nozzles are fixed on the storage cylinder.

[0007] Preferably, two sealing rings are fixed to the outer wall of the connecting column, and the sealing rings are in contact with the inner wall of the receiving groove.

[0008] Preferably, the rear side of the box body is provided with an installation groove, the inner bottom surface of the box body is provided with a sliding groove, the inner bottom surface of the sliding groove is provided with a discharge hole, the discharge hole is connected to the installation groove, the inner wall of the installation groove is slidably connected to a collection box, and the inlet of the collection box corresponds to the discharge hole.

[0009] Preferably, a sealing gasket is fixed to the top surface of the collection box, and the sealing gasket is in contact with the inner top surface of the mounting groove.

[0010] Preferably, the protective cover has a rotating hole on the left side, a rotating column is inserted into the inner wall of the rotating hole, the rotating column is connected to the storage cylinder, the outer wall of the rotating column has an external thread, a fixing ring is provided on the outer wall of the rotating column, the inner wall of the fixing ring has an internal thread, and the fixing ring is threaded to the threaded end of the rotating column.

[0011] Preferably, the top surface of the protective cover has an installation hole, and a transparent panel is fixed to the inner wall of the installation hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated action of the mounting plate, drive motor, L-shaped plate, through holes, grid plate, storage cylinder, and spray head, the system achieves the tumbling and water-fluid washing and slag removal of Polygonatum sibiricum. The linkage between mechanical drive and fluid washing effectively removes adhering mud and impurities from the surface of Polygonatum sibiricum. Simultaneously, the synergistic effect of the grid plate's screening and water-fluid washing prevents blind spots caused by Polygonatum sibiricum accumulation, significantly improving the impurity removal rate and material purity, avoiding the residue of mud and impurities, thereby increasing the purity of Polygonatum sibiricum after screening and slag removal, and thus improving the working efficiency of the screening and slag removal mechanism. The sealing ring increases the sealing between the connecting column and the receiving tank, effectively blocking impurities such as mud and sand from entering the receiving tank and affecting the internal structure.

[0014] Second, the inclined chute utilizes gravity to automatically slide the screened Polygonatum (or residue) towards the lower discharge port, directly guiding it into the collection box and preventing accumulation within the box. This achieves rapid separation and centralized collection of Polygonatum and residue, improving screening efficiency. The sealing gasket enhances the seal between the collection box and the discharge port, effectively preventing leakage of discharged residue or water.

[0015] Third, the threaded connection between the fixing ring and the rotating column allows for limiting and fixing of the storage cylinder and the rotating column after angle adjustment, ensuring the spray angle of the storage cylinder and the spray head, and effectively preventing angular deviation of the storage cylinder. The transparent panel allows operators to easily observe the slag removal process of the Polygonatum sibiricum inside the tank, enabling them to adjust the drive motor data based on the slag removal status, thereby ensuring the slag removal efficiency of the Polygonatum sibiricum.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a processing, screening, and slag removal mechanism includes a mounting plate 1, which is rotatably mounted inside a housing 2. A drive motor 3 is fixed to the outside of the left side of the housing 2, and one end of the output shaft of the drive motor 3 extends into the housing 2. The mounting plate 1 is fixed to the outer wall of the output shaft of the drive motor 3. Several receiving grooves 4 are provided on both the top and bottom surfaces of the mounting plate 1. Two L-shaped plates 5 are provided on the inner wall of the housing 2. The ends of the L-shaped plates 5 are made of rubber, and several through holes 6 are provided on the L-shaped plates 5. Several connecting posts 7 are fixed on the L-shaped plates 5 and inserted into the receiving grooves 4. A spring 8 is connected to the connecting column 7, and the other end of the spring 8 is connected to the inner bottom surface of the receiving groove 4. A grid plate 9 is detachably snapped onto the inner wall of the box body 2. An L-shaped plate 5 is rotatably set in the hole on the grid plate 9. A protective cover 10 is rotatably connected to the box body 2 via a hinge. A storage cylinder 11 is rotatably set on the protective cover 10. The storage cylinder 11 is connected to the output end of an external water supply device via a connecting pipe. Several spray heads 1101 are fixed on the storage cylinder 11. Two sealing rings 12 are fixed on the outer wall of the connecting column 7. The sealing rings 12 are in contact with the inner wall of the receiving groove 4.

[0023] When it is necessary to screen and remove slag from Polygonatum during use, firstly, spread the Polygonatum material evenly on the grid plate 9, then close the protective cover 10. Subsequently, the operator can adjust the angle of the storage cylinder 11 and the spray head 1101 by rotating the rotating column 19, so that the spray trajectory of the spray head 1101 accurately covers the Polygonatum on the grid plate 9. After the angle is calibrated, tighten the fixing ring 20 clockwise. The fixed ring 20 and the rotating column 19 are used to lock the position of the storage cylinder 11 and the spray head 1101 to ensure the angle is stable during the spraying process.

[0024] At this time, the external water supply equipment, drive motor 3 and spray head 1101 can be started: the external water supply equipment will output water to the storage cylinder 11 through the connecting pipe, and then the spray head 1101 will spray water onto the Polygonatum sibiricum. On the one hand, the surface of the Polygonatum sibiricum material is rinsed to remove the attached mud, sand and dust and other light impurities. On the other hand, the pores of the grid plate 9 and the surface of the L-shaped plate 5 are pre-cleaned to avoid pore blockage during the subsequent screening process.

[0025] At the same time, the drive motor 3 will drive the mounting plate 1 to rotate counterclockwise. The mounting plate 1 drives the two L-shaped plates 5 to move synchronously through the elastic transmission structure of the connecting column 7 and the spring 8. Under the elastic force of the spring 8, the L-shaped plates 5 always keep in contact with the inner wall of the box 2. As the mounting plate 1 continues to rotate, the L-shaped plates 5 periodically pass through the holes of the grid plate 9 to stir and disperse the Polygonatum material on the grid plate 9, ensuring that the material is fully in contact with the water flow. After stirring and rinsing, the mud and sand residues that fall off the surface of Polygonatum and the secondary Polygonatum particles with a particle size smaller than the holes of the grid plate 9 fall into the inclined chute 14 at the bottom of the box 2 through the holes of the grid plate 9. Under the gravity guidance of the chute 14, the material slides along the inclined surface to the discharge hole 15, and finally falls accurately into the corresponding collection box 16 below through the discharge hole 15, realizing the centralized recycling of residues and secondary materials.

[0026] Finally, after the screening operation is completed, turn off the water spray head 1101, drive motor 3 and external water supply equipment in sequence to ensure that the equipment gradually stops running. After the equipment has completely stopped, open the protective cover 10, check the state of residual material on the grid plate 9, and use special tools to remove the qualified Polygonatum material after screening from the grid plate 9 to complete the screening and slag removal operation of Polygonatum. If it is necessary to pause the operation later, the external water supply equipment and water spray head 1101 can be turned on again to rinse the inside of the box 2, the grid plate 9 and the L-shaped plate 5 for a short time to remove residual material and impurities and prepare for the next operation.

[0027] Through the coordinated action of mounting plate 1, drive motor 3, L-shaped plate 5, through hole 6, grid plate 9, storage cylinder 11, and spray head 1101, the tumbling and water rinsing of Polygonatum sibiricum are achieved, enabling sieving and slag removal. The linkage between mechanical drive and fluid rinsing effectively removes adhering mud and impurities from the surface of Polygonatum sibiricum. Simultaneously, the synergistic effect of the grid plate 9's sieving and water rinsing prevents blind spots caused by Polygonatum sibiricum accumulation, significantly improving impurity removal rate and material purity, avoiding the residue of mud and impurities, thereby increasing the purity of Polygonatum sibiricum after sieving and slag removal, and thus improving the working efficiency of the sieving and slag removal mechanism. The sealing ring 12 increases the sealing between the connecting column 7 and the receiving tank 4, blocking impurities such as mud and sand, effectively preventing impurities from entering the receiving tank 4 and affecting the internal structure.

[0028] like Figures 1-4As shown, a mounting groove 13 is provided on the rear side of the box body 2, a sliding groove 14 is provided on the inner bottom surface of the box body 2, and a discharge hole 15 is provided on the inner bottom surface of the sliding groove 14. The discharge hole 15 is connected to the mounting groove 13. A collection box 16 is slidably connected to the inner wall of the mounting groove 13. The inlet of the collection box 16 corresponds to the discharge hole 15. A sealing gasket 17 is fixed on the top surface of the collection box 16. The sealing gasket 17 is in contact with the inner top surface of the mounting groove 13. A rotating hole 18 is provided on the left side of the protective cover 10. A rotating column 19 is inserted into the inner wall of the rotating hole 18. The rotating column 19 is connected to the storage cylinder 11. An external thread is provided on the outer wall of the rotating column 19. A fixing ring 20 is provided on the outer wall of the rotating column 19. An internal thread is provided on the inner wall of the fixing ring 20. The fixing ring 20 is threadedly connected to the threaded end of the rotating column 19. A mounting hole 21 is provided on the top surface of the protective cover 10. A transparent panel 22 is fixed on the inner wall of the mounting hole 21.

[0029] During use, the inclined chute 14 utilizes gravity to automatically slide the screened Polygonatum (or residue) towards the lower discharge hole 15, directly guiding the screened Polygonatum (or separated residue) into the collection box 16. This prevents accumulation within the box 2, achieving rapid separation and centralized collection of Polygonatum and residue, thus improving screening efficiency. The sealing gasket 17 enhances the seal between the collection box 16 and the discharge hole 15, effectively preventing leakage of discharged residue or water. The threaded connection between the fixing ring 20 and the rotating column 19 allows for the limiting and fixing of the storage cylinder 11 and the rotating column 19 after angle adjustment, ensuring the spray angle of the storage cylinder 11 and the water spray head 1101, effectively preventing angular deviation of the storage cylinder 11. The transparent panel 22 allows operators to easily observe the residue removal process of the Polygonatum within the box 2, enabling them to adjust the data of the drive motor 3 based on the residue removal status, thereby ensuring efficient residue removal.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
