Description

Technical Field

[0001] The utility model relates to the technical field of material screening equipment, in particular to a screening equipment used for ginseng processing. Background Art

[0002] Ginseng is a precious traditional Chinese medicine, and its quality is directly related to its efficacy and safety. Therefore, screening before processing is crucial. Sorting machines can also grade ginseng according to its size, shape, and other characteristics. Different grades of ginseng vary in efficacy and price. Therefore, grading through screening machines can meet the needs of different customers.

[0003] Existing screening machines generally use mechanical screening methods to screen ginseng by size. Mechanical screening machines use screens or rollers of different sizes to grade ginseng according to diameter or length. The ginseng is rolled or vibrated inside the machine, and ginseng of different sizes is intercepted by different screens, thus achieving separation. However, ginseng varies in size and shape, and different batches of ginseng may have significant size differences. Therefore, by adjusting the spacing between the rollers, the screening machine can ensure that ginseng can adapt to different sizes and achieve more accurate grading. However, adjusting the spacing of the existing screening rollers generally requires removing the fixed roller mounting bracket from the curved plate chain inside the screening machine and re-adjusting the roller installation position. Furthermore, the distance adjustment accuracy between the two rollers cannot be further improved, which affects the ginseng size screening accuracy. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 5 As shown, the utility model provides a screening device for human participation processing, including a first-level screening machine 1, a second-level screening machine 2 and a third-level screening machine 3. A motor 4 is fixedly installed on one side of the first-level screening machine 1, the second-level screening machine 2 and the third-level screening machine 3, and the motor 4 is electrically connected to an external controller through a connecting line. A chain conveying mechanism 5 is also provided in the first-level screening machine 1, the second-level screening machine 2 and the third-level screening machine 3, respectively. The driving sprocket of the chain conveying mechanism 5 is fixedly connected to the corresponding output end of the motor 4. A plurality of screeners 9 are provided on the chain conveying mechanism 5. The screener 9 includes a mounting cylinder 10. A plurality of expansion plates 11 are movably installed on the outside of the mounting cylinder 10, and a rubber gasket 12 is fixedly connected between the two expansion plates 11. The mounting cylinder 10 is fixedly installed on the chain conveying mechanism 5. A first lower hopper 13 is fixedly installed at the lower end of the first-level screening machine 1, a second lower hopper 14 is fixedly installed at the lower end of the second-level screening machine 2, and a plurality of third lower hoppers 15 are fixedly installed at the lower end of the third-level screening machine 3.

[0022] like Figure 3-Figure 4 As shown, mounting shafts 16 are fixedly mounted at both ends of the mounting tube 10, and a plurality of slots 17 are provided on the outside of the mounting tube 10. The longitudinal cross-section of the slots 17 is T-shaped. The opening of the slots 17 provides conditions for the movable installation of the expansion piece 11.

[0023] like Figure 3-Figure 5As shown, a connecting piece 19 is provided on one side of the expansion piece 11, and a plurality of tension springs 6 are fixedly installed on one side of the connecting piece 19. A plurality of plug-in blocks 18 are fixedly installed on the side of the rubber gasket 12 relative to the expansion piece 11. The plug-in blocks 18 are inserted into the corresponding through holes in the expansion piece 11 and the connecting piece 19 and are fixedly connected by screws, and the end of the tension spring 6 away from the connecting piece 19 is inserted into the corresponding card slot 17. By connecting the two expansion pieces 11 through the rubber gasket 12, the tension spring 6 can be used to achieve synchronous expansion of the plurality of expansion pieces 11, thereby adjusting the distance between the two screeners 9 and controlling the screening size of the ginseng.

[0024] like Figure 2-Figure 4 As shown, a fixing seat 8 is inserted into one end of the mounting shaft 16, and the mounting tube 10 located between the fixing seat 8 and the expansion piece 11 is also threadedly connected to the adjustment block 7. The adjustment block 7 is a truncated cone structure. Through the setting of the two adjustment blocks 7, the tension spring 6 and the connecting piece 19 can be used to synchronously expand or contract multiple expansion pieces 11. The fixing seat 8 is fixedly installed on the bent plate chain of the chain conveying mechanism 5 by screws.

[0025] It should be noted that the present invention is a screening device for human participation in the process of processing. When the expansion of the multiple expansion pieces 11 is adjusted synchronously, the two adjustment blocks 7 can be rotated synchronously on one end of the mounting tube 10, so that the two adjustment blocks 7 can rotate relative to each other on the mounting tube 10. As a result, the two adjustment blocks 7 use the outer slope to synchronously squeeze and expand one end of the multiple connecting pieces 19, so that the multiple connecting pieces 19 synchronously drive the multiple expansion pieces 11 to expand outward. At the same time, the connecting piece 19 stretches the tension spring 6. As the expansion piece 11 expands outward, the two expansion pieces 11 will stretch the rubber gasket 12 connected to them, thereby ensuring the connectivity between the multiple expansion pieces 11, thereby reducing the distance between the two screeners 9.

[0026] When increasing the distance between the two screeners 9, it is only necessary to rotate the two adjusting blocks 7 in opposite directions on the outside of the mounting cylinder 10. As a result, the end of the slope with a smaller longitudinal cross-section on the outside of the adjusting block 7 gradually engages with the connecting piece 19, thereby cooperating with the force of the tension spring 6 to move the multiple expansion pieces 11 toward the mounting cylinder 10, thereby reducing the longitudinal cross-sectional size of the tubular structure composed of the multiple expansion pieces 11 and the rubber gasket 12, thereby increasing the distance between the two screeners 9. When screening ginseng, due to the different distances between the screeners 9 in the first-level screening machine 1, the second-level screening machine 2, and the third-level screening machine 3, the ginseng can be subjected to a conveyor-type three-level screening.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
