Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine screening technology, specifically a vibrating sieve for screening medicinal materials. Background Technology
[0002] Medicinal materials are plant, animal, and mineral materials widely used in traditional Chinese medicine. They have the function of regulating human functions and treating diseases. Generally, they include animal and plant medicinal materials. Before being used in medicine, medicinal materials need to be processed, which involves washing, slicing, and sieving machines. Among them, sieving machines are used to screen and pre-select medicinal materials of different sizes of the same kind, so as to facilitate slicing, drying, and other processing.
[0003] When using a screening machine, Chinese medicinal materials are placed on a screen for screening. However, traditional screening machines generally have fixed screen holes, which can only screen medicinal materials of a fixed diameter and cannot screen out finer individual materials. This results in poor practicality, and the process of changing the screen is cumbersome, time-consuming, and labor-intensive. Therefore, a vibrating screening machine for screening medicinal materials is proposed to address the above problems. Utility Model Content

The sliding shaft and the collar are fixedly connected. The end of the sliding shaft is slidably connected through the slot. A slider is slidably connected to the surface of the base plate by a spring. Several slots are formed on the surface of the sliding shaft relative to the position of the slider.
[0012] Preferably, a protective cover is fixedly connected to the surface of the adjusting plate, the positioning mechanism is disposed on the protective cover, and a stepped groove is formed on the surface of the base plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] Please see Figure 1-6As shown, a vibrating sieve for screening medicinal materials includes a body 1, a sieve plate 3 fixedly installed on the body 1, and a discharge port 2 provided on the surface of the body 1.
[0032] The screen plate 3 has two layers, upper and lower, and the discharge port 2 is located at the bottom of the lower screen plate 3;
[0033] A bottom block 19 and a bottom plate 15 are fixedly connected to the surface of the sieve plate 3. The bottom block 19 and the bottom plate 15 have the same width and height.
[0034] An adjusting plate 5 is movably installed on the sieve plate 3. The surface of the adjusting plate 5 is also provided with mesh holes, and the mesh holes of the adjusting plate 5 are the same as those of the sieve plate 3.
[0035] A collar 9 is slidably connected between the base plate 15 and the base block 19 via a spring, and the adjusting plate 5 is mounted on the collar 9 via a positioning mechanism.
[0036] A fixing mechanism is provided on the collar 9;
[0037] The fixing mechanism includes a fixing shaft 13, which is fixedly installed on the side of the base plate 15 and the base block 19 that are close to each other. The fixing shaft 13 is hollow and a sliding shaft 21 is slidably connected inside the fixing shaft 13. A slot 12 is opened on the surface of the fixing shaft 13. A collar 9 is slidably connected in the slot 12 and the sliding shaft 21 is fixedly connected to the collar 9. The end of the sliding shaft 21 is slidably connected through the slot 12. A slider 20 is slidably connected to the surface of the base plate 15 by a spring. Several slots 22 are opened on the surface of the sliding shaft 21 relative to the position of the slider 20.
[0038] During operation, the adjusting plate 5 is placed on the sieve plate 3, and then fixed on the sieve plate 3 by the positioning mechanism. At this time, the sliding shaft 21 is slidable, which drives the collar 9 to move. At the same time, the collar 9 drives the adjusting plate 5 to move. After the collar 9 is moved to the appropriate position, the slider 20 will be inserted into the slot 22 under the action of the spring, fixing the position of the adjusting plate 5. At this time, the sieve holes on the adjusting plate 5 are misaligned with the sieve holes on the surface of the sieve plate 3, thereby achieving the purpose of adjusting the diameter of the sieve holes on the surface of the sieve plate 3, and thus achieving the purpose of screening Chinese medicinal materials of different diameters. This allows the screening machine to screen out more fine individual materials, greatly improving its practicality. Under the action of the spring on the surface of the collar 9, the slider 20 is pulled upward, and the spring drives the collar 9 to return to its original position. The collar 9 drives the adjusting plate 5 to hit the bottom block 19, and the resulting vibration can shake off the Chinese medicinal materials stuck between the adjusting plate 5 and the sieve plate 3, making it easier for the staff to clean them up.
[0039] A protective cover 11 is fixedly connected to the surface of the adjusting plate 5. A positioning mechanism is set on the protective cover 11. A stepped groove 17 is opened on the surface of the base plate 15. The positioning mechanism includes a fixing block 8, which is fixedly installed on the surface of the protective cover 11. A support rod 25 is rotatably connected to the surface of the fixing block 8 via a hinge. There are two support rods 25, which are symmetrically designed. A spring is fixedly connected between the sides of the pair of support rods 25 that are close to each other. A fixing bolt 23 is threadedly connected to the surface of the fixing block 8. A groove 18 is opened on the surface of the collar 9.
[0040] During operation, when the adjusting plate 5 is placed on the screen plate 3, the protective cover 11 will be fitted onto the base plate 15 and the base block 19. At this time, the fixing block 8 on the protective cover 11 will drive the support rod 25 to be locked on the surface of the groove 18. Then, the fixing bolt 23 is rotated, and the fixing bolt 23 moves downward through the thread, slowly opening the two support rods 25 and further fixing the adjusting plate 5 body 1 to prevent it from falling off during vibration. Through the design of the support rod 25 and the fixing bolt 23, the filter screen can be replaced more conveniently and quickly, thereby indirectly improving the screening efficiency. The spring is used to reset the two support rods 25, so that the width of the opening of the two support rods 25 is smaller than the width of the groove 18.
[0041] The end of the support rod 25 is provided with an angle, and the end of the sliding shaft 21 that passes through the fixed shaft 13 is fixedly connected to the pull rod 6. The surface of the pull rod 6 is provided with anti-slip texture. The surface of the part of the slider 20 that is inserted into the slot 22 is provided with an arc corner. The slider 20 is "T" shaped. The surface of the slider 20 is fixedly connected with a pull ring. There are two fixing mechanisms, and they are designed symmetrically with respect to the central axis of the adjusting plate 5.
[0042] During operation, the adjustment plate 5 can be installed more quickly and accurately by using the beveled end of the support rod 25 in conjunction with the stepped groove 17. The pull ring makes it easier to slide the slider 20. The design of the two fixed structures makes the adjustment plate 5 more stable and avoids displacement.
[0043] Example 2
[0044] Please see Figure 7 As shown in the first embodiment, as another implementation of this utility model, a separation strip 26 is fixedly connected between the base plate 15 and the base block 19; during operation, the separation strip 26 can prevent the residue of Chinese medicinal materials from remaining between the base block 19 and the base plate 15, which would be inconvenient for workers to clean.
