Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine screening technology, specifically a screening machine for pretreatment of traditional Chinese medicinal materials. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to natural medicines and their processed products used to prevent and treat diseases and regulate bodily functions. Its sources include plants, animals, and minerals, and it is made into various preparations through unique processes such as processing and compatibility. According to the source, it can be classified as plant medicine, animal medicine, and mineral medicine, and according to the efficacy, it can be classified as exterior-releasing medicine, heat-clearing medicine, deficiency-tonifying medicine, and blood-activating and stasis-removing medicine.

[0003] In the processing of traditional Chinese medicine, herbs of different sizes need to be classified to facilitate subsequent slicing. However, traditional vibrating screens are highly efficient at screening spherical herbs, but their screening effect is not ideal for columnar herbs, requiring repeated feeding and screening, which results in very low screening efficiency. Therefore, a screening machine for the pretreatment of traditional Chinese medicine is proposed to address the above problems. Utility Model Content

A plurality of limiting rods are fixedly connected to the surface of the support ring, and the crossbar is positioned at the limiting rods.

[0014] The surface is slidably connected by a spring, and the surface of the crossbar is rotatably connected to an adjusting rod by a hinge. The end of the adjusting rod away from the crossbar is connected to the annular plate by a hinge.

[0015] Preferably, the number of limiting rods is the same as the number of crossbars, and they are evenly distributed.

[0031] 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.

[0032] Example 1

[0033] Please see Figure 1-4 As shown, a screening machine for pretreatment of Chinese medicinal materials includes a base frame 1, a ring frame 2 and a support rod 3. The ring frame 2 is fixedly installed on the surface of the base frame 1, and the support rod 3 is arc-shaped and fixed on the surface of the ring frame 2.

[0034] Support ring 5, there are two support rings 5, a pair of support rings 5 ​​are symmetrically distributed about the central axis of the frame 2;

[0035] Several crossbars 7 are provided between a pair of support rings 5, and adjustment mechanisms are provided at both ends of the crossbars 7;

[0036] A motor is fixedly connected to the surface of the frame 2, and a connecting shaft 10 is rotatably connected to the surface of the support rod 3 via a bearing. A rubber wheel is fixedly connected to the surface of the connecting shaft 10, and the connecting shaft 10 is driven by the motor via a conveyor belt.

[0037] The rubber wheel is in contact with the support ring 5;

[0038] A receiving plate 9 is fixedly connected to the surface of the frame 2, and a discharge port 8 is provided on the surface of the receiving plate 9;

[0039] A pair of support rings are divided into a feed ring and a discharge ring, with the feed ring connected to the hopper.

[0040] An adjusting seat 11 is threadedly connected to the surface of the base frame 1;

[0041] The adjustment mechanism includes an annular plate 19, which is rotatably connected to the surface of the support ring 5. A fixed shaft 17 is fixedly connected to the surface of the annular plate 19. A through groove 16 is opened on the surface of the support ring 5. The fixed shaft 17 is slidably connected through the through groove 16. A fixing mechanism is provided on the surface of the fixed shaft 17. Several limiting rods 15 are fixedly connected to the surface of the support ring 5. A crossbar 7 is slidably connected to the surface of the limiting rods 15 by a spring. An adjusting rod 12 is rotatably connected to the surface of the crossbar 7 by a hinge. The end of the adjusting rod 12 away from the crossbar 7 is connected to the annular plate 19 by a hinge. The number of limiting rods 15 is the same as the number of crossbars 7 and they are equidistantly distributed. The cross section of the receiving plate 9 is arc-shaped and has an angle inclined towards the discharge port 8.

[0042] During operation, first place the base frame 1 stably, then adjust the entire device to the required angle using the adjusting seat 11 and start the motor. Then, place the medicinal herbs into the feed ring inlet. The motor drives the two support rings 5 ​​to rotate, sieving the columnar medicinal herbs. The design of multiple crossbars 7 allows for sieving of columnar medicinal herbs, avoiding repeated feeding and sieving, thus significantly improving sieving efficiency. If sieving of medicinal herbs of different diameters and types is required, slide the fixed shaft 17, causing it to move the annular plate 19. As the annular plate 19 moves, it drives the adjusting rod 12 to rotate at different angles. The larger the angle between the adjusting rod 12 and the limiting rod 15, the closer the crossbar 7 is to the annular plate 19 under the influence of the spring.

[0043] The larger the gap between rods 7, the more effective it is to sieve Chinese medicinal materials of different diameters and types, thus greatly improving practicality.

[0044] The fixing mechanism includes a rotating rod 6, which is rotatably connected within a fixed shaft 17. A sliding insert shaft 18 is connected to the surface of the fixed shaft 17 via a spring. Two insert shafts 18 are provided and are symmetrically designed. A pull rope is fixedly connected to the surface of the insert shaft 18, with the other end of the pull rope passing through the fixed shaft 17 and fixedly connected to the rotating shaft. Several positioning holes 25 are provided on the surface of the through groove 16 relative to the position of the insert shaft 18. During operation, after adjusting the spacing between the crossbars 7 to the required width, the spring will drive the insert shaft 18 to insert into the positioning holes 25, fixing the position of the crossbars 7. This prevents the crossbars 7 from swaying randomly when the support rod rotates, thus preventing them from losing their screening effect. If the position of the crossbars 7 needs to be adjusted, the rotating rod 6 is directly rotated, causing the rotating rod 6 to rewind the pull rope. At this time, the two insert blocks can be pulled towards each other, thereby releasing the restriction on the crossbars 7.

[0045] Example 2

[0046] Please see Figure 5-6 As shown in the first embodiment, as another implementation of this utility model, the receiving plate 9 is made of elastic material. A main magnetic block 26 is fixedly connected to the surface of the support ring 5. An impact head 27 is rotatably connected to the surface of the receiving plate 9 via a spring. A secondary magnetic block is fixedly connected to the surface of the impact head 27 relative to the position of the main magnetic block 26. During operation, the support ring 5 rotates under the drive of the motor, and at the same time, the support ring 5 drives the main magnetic block 26 on its surface to rotate. When the main magnetic block 26 rotates to the position of the secondary magnetic block, the main magnetic block 26 and the secondary magnetic block attract each other in opposite phases, causing the impact head 27 to move away from the receiving plate 9. After the main magnetic block 26 passes the secondary magnetic block, the spring drives the impact head 27 to reset and impact the receiving plate 9, causing the receiving plate 9 to vibrate. This allows the residual Chinese medicine on the surface of the receiving plate 9 to be guided to the discharge port 8 more quickly, avoiding stagnation and blockage.
