Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, and in particular to a manual screening table for processing traditional Chinese medicine. Background Technology

[0002] Manual screening tables for Chinese medicine processing are specifically designed for the primary processing stage of Chinese medicine. Their core function is to assist workers in screening out impurities (such as mud, insect-infested parts, and moldy parts) from medicinal materials, providing good raw materials for subsequent processing, slicing, and compounding. They are commonly found in Chinese medicine processing plants, Chinese medicinal material markets, and traditional Chinese medicine factories.

[0003] For example, a traditional Chinese medicine screening machine with authorization announcement number "CN211937810U" has its discharge pipe located on the lower side of the chamber, which facilitates the discharge of Chinese medicinal herbs. The feed hopper can continuously add Chinese medicinal herbs into the chamber while the screening machine is working, allowing the chamber to operate continuously and improving screening efficiency. Traditional manual screening of Chinese medicinal herbs mostly relies on a "horizontal fixed table." Workers need to repeatedly spread and disperse the herbs by hand, and then manually move the screened material to the collection area. The entire process requires bending over and lifting arms repeatedly, which is especially physically demanding when dealing with large quantities of herbs. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing a manual screening table for processing traditional Chinese medicine, thereby reducing the workload of workers.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This manual screening table for processing traditional Chinese medicine includes a box body and support legs. The four corners of the lower end of the box body are fixedly connected to the support legs. Vibration motors are installed on the left and right sides of the lower end of the box body. A screening structure is provided at the upper end of the box body. A box door is installed at the front end of the box body. Round rods are fixedly connected to both sides of the inner wall of the box body. A defective product collection structure is provided inside the box body.

[0006] To further improve the design, the screening structure includes an inclined plate. An inclined plate is fixedly connected to the upper end of the box. A filter screen is installed in the middle of the inclined plate. Baffles are fixedly connected to both the front and rear sides of the upper end of the inclined plate. Multiple speed reduction strips are installed at the upper end of the inclined plate.

[0007] To further improve the design, horizontal blocks are fixedly connected to both the front and rear sides of the right end of the housing.

[0008] To further improve the design, the inner wall of the cross block is threadedly connected to the qualified product storage box via bolts.

[0009] Further improvements include a non-conforming product collection structure comprising a storage box and a groove. The storage box is slidably connected to a round rod via protrusions machined on both sides of its outer wall. A first magnet is installed at the rear end of the storage box, and the first magnet is magnetically connected to a second magnet. A second magnet is installed on the inner wall of the box, and a groove is provided on the inner wall of the box door.

[0010] Further improvements include ensuring that the inner wall of the groove contacts the round rod.

[0011] The beneficial effects of this utility model are as follows: Through the combination of the screening structure and the box body, the Chinese medicinal materials pass through the filter screen in the middle of the inclined plate. Unqualified products with a size smaller than the filter screen aperture fall through the filter screen holes under the action of gravity and vibration and enter the storage box inside the lower box body. Qualified products with a size larger than the filter screen aperture continue to slide along the inclined plate. Multiple deceleration strips installed at the upper part of the inclined plate can increase the friction between the Chinese medicinal materials and the surface of the inclined plate, and slow down the sliding speed of the Chinese medicinal materials. This allows sufficient time for manual screening by the staff, who can visually identify and remove unqualified medicinal materials such as mold and insect infestation that remain during the sliding process. The baffles on the front and rear sides of the inclined plate can prevent the Chinese medicinal materials from falling off the sides of the inclined plate during vibration and sliding. Through the above methods, the workload of workers is reduced. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6 In this embodiment, a manual screening table for processing traditional Chinese medicine includes a box body 1 and support legs 2. The four corners of the lower end of the box body 1 are fixedly connected to the support legs 2. The support legs 2 are in contact with the ground and provide support for the box body 1. Vibration motors 4 are installed on the left and right sides of the lower end of the box body 1. The upper end of the box body 1 is provided with a screening structure 3. The front end of the box body 1 is equipped with a box door 7, which is installed inside the box body 1 by bolts.

[0021] Both sides of the inner wall of the box 1 are fixedly connected with round rods 5. The inside of the box 1 is equipped with a defective product collection structure 6. Both the front and rear sides of the right end of the box 1 are fixedly connected with horizontal blocks 9. The inner wall of the horizontal block 9 is threadedly connected to the qualified product storage box 8 by bolts. The qualified product storage box 8 is installed on the horizontal block 9 by bolts. The inner wall of the groove 604 is in contact with the round rods 5. The groove 604 provides support for the round rods 5 and prevents the round rods 5 from vibrating on a large scale due to the vibration motor 4.

[0022] See attached document Figure 1 and Figure 2 The screening structure 3 includes an inclined plate 301. An inclined plate 301 is fixedly connected to the upper end of the box body 1. A filter screen 302 is installed in the middle of the inclined plate 301. The filter screen 302 is used to screen out incomplete Chinese medicine, that is, small Chinese medicine, and can also screen out impurities such as stones. Baffles 304 are fixedly connected to the front and rear sides of the upper end of the inclined plate 301. The baffles 304 prevent the Chinese medicine above the inclined plate 301 from flying out when the inclined plate 301 vibrates. Multiple deceleration strips 303 are installed at the upper end of the inclined plate 301. The deceleration strips 303 play a deceleration role, allowing the Chinese medicine to stay for a longer time, which allows for better manual screening.

[0023] See attached document Figure 2-4 The defective product collection structure 6 includes a storage box 601 and a groove 604. The storage box 601 is slidably connected to the round rod 5 through protrusions machined on both sides of the outer wall. The storage box 601 slides on the round rod 5 through the protrusions. A first magnet 602 is installed at the rear end of the storage box 601. The first magnet 602 is magnetically connected to a second magnet 603. The second magnet 603 is installed on the inner wall of the box body 1. A groove 604 is opened on the inner wall of the box door 7. The groove 604 limits the round rod 5.

[0024] Working principle:

[0025] When using a manual screening table for processing traditional Chinese medicine:

[0026] Grading and screening using inclined plates and screens:

[0027] The staff pours the Chinese medicinal materials to be screened into the inclined plate 301 from the left end (higher side). The inclined plate 301 is designed with the left side higher than the right side. The external power supply of the vibration motor 4 is turned on and the vibration motor 4 is started. Combined with the vibration force of the vibration motor 4, the Chinese medicinal materials slide naturally to the right along the inclined plate 301. During the sliding process, the Chinese medicinal materials pass through the filter screen 302 in the middle of the inclined plate 301. Unqualified products with a size smaller than the filter screen aperture (such as small impurities and broken medicinal materials) fall out of the filter screen 302 under the action of gravity and vibration and enter the storage box 601 inside the lower box 1. Qualified products with a size larger than the filter screen aperture continue to slide along the inclined plate 301 and finally slide into the qualified product storage box 8 on the right side, completing the preliminary "size grading and screening".

[0028] The auxiliary functions of speed bumps and barriers:

[0029] Multiple deceleration strips 303 installed on the upper end of the inclined plate 301 can increase the friction between the Chinese medicinal materials and the surface of the inclined plate 301, and slow down the sliding speed of the Chinese medicinal materials. This allows sufficient time for manual screening by the staff, who can visually identify and remove unqualified medicinal materials such as mold and insect infestation that remain during the sliding process, thereby further improving the screening accuracy. At the same time, the baffles 304 on the front and rear sides of the inclined plate 301 can prevent the Chinese medicinal materials from falling off the sides of the inclined plate during vibration and sliding, avoiding material loss and ensuring that the screening process is carried out in an orderly manner.

[0030] After the screening operation is completed, turn off the vibration motor 4, remove the bolts connecting the box door 7 to the box body 1, open the box door 7 at the front of the box body 1, and slide the storage box 601 outward along the round rod 5 to separate the first magnet 602 and the second magnet 603. When the first magnet 602 and the second magnet 603 attract each other, they can prevent the storage box 601 from shifting during vibration. This allows for the cleaning or subsequent processing of the unqualified products collected inside. After cleaning, slide the storage box 601 back into the round rod 5 and fix it by the attraction of the two magnets. Close the box door 7 and turn off all power. This completes the workflow of the manual screening table for traditional Chinese medicine processing.

[0031] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
