Description
Technical Field
[0001] The utility model relates to the technical field of Chinese medicinal material processing, in particular to a Chinese medicinal material crushing device. Background Art
[0002] Traditional Chinese medicine originated in China. Under the guidance of traditional Chinese medicine theory, it is used to prevent, diagnose, treat diseases or regulate human functions. Most of them are herbal medicines, but there are also animal medicines, mineral medicines and some chemical and biological products. In my country, there is a history of thousands of years of development and application of traditional Chinese medicine. In the process of making Chinese medicinal materials, it is usually necessary to crush the Chinese medicinal materials to improve the utilization of the medicinal properties of Chinese medicinal materials. Crushing is an important link in the processing of Chinese medicinal materials and the production process of Chinese medicinal preparations. After crushing, the Chinese medicinal materials can increase the surface area of the medicine, promote the dissolution of the medicine, facilitate the preparation of various drug dosage forms, accelerate the dissolution of the active ingredients in the medicinal materials, facilitate the preparation, administration and efficacy of the medicine, and facilitate the drying and storage of fresh medicinal materials.
[0003] The crushing of Chinese herbal medicine is the process of crushing large pieces of solid materials into appropriate fineness by mechanical force. The journal "Agricultural Product Processing" No. 10, 2011 introduced the HK-180 universal crusher developed and launched by Guangzhou Xulang Machinery Equipment Co., Ltd. This machine crushes the material to be crushed by the relative rotation between the movable toothed disc and the fixed toothed disc. It is suitable for the crushing of Chinese herbal medicines. However, the crushed Chinese herbal medicines will flow out from the same outlet, which affects the crushing effect of Chinese herbal medicines to a certain extent. The reason is that during the crushing process, some Chinese herbal medicines that do not meet the degree of crushing will inevitably appear in the crushed Chinese herbal medicines. If these unqualified Chinese herbal medicines are directly collected or enter the next process without any treatment, it means that the unqualified Chinese herbal medicines will inevitably be accepted, which will undoubtedly have a certain impact on the overall quality of Chinese herbal medicines, bring difficulties to the subsequent processing flow, and also affect the final quality of Chinese herbal medicines. In addition, in this case, it is not convenient to screen and select in the subsequent processing flow. Summary of the invention

[0027] In this embodiment, the bottom of the crushing box 2 is set in a slope shape, and a support plate 14 is set on the right side wall of the crushing box 2. The support plate 14 is U-shaped, and the material receiving box 8 is set on the support plate 14. The material receiving box 8 is provided with a handle 15. The bottom of the crushing box 2 is set in a slope shape, so that the Chinese medicinal materials filtered by the sieve plate 6 can fall into the first discharge port 4 and then be discharged for collection, preventing some Chinese medicinal materials from remaining at the bottom of the crushing box 2.
[0028] Please refer again Figure 2 and Figure 4 The pulverizing roller 5 is provided with a rotating shaft 16, and the number of the pulverizing roller 5 and the rotating shaft 16 are both two. The side walls on both sides of the pulverizing box 2 are respectively provided with two mounting grooves, and the two mounting grooves are respectively provided on the two rotating shafts 16. A bearing seat 17 is installed on the part of each rotating shaft 16 located outside the pulverizing box 2, and a gear 18 is provided on the side of each rotating shaft 16 away from the pulverizing box 2, and the two gears 18 are meshed with each other.
[0029] Please refer again Figure 5 The transmission assembly includes a driving pulley 19 coaxially arranged on the output shaft of the motor 11, and a driven pulley 20 is arranged on one side of the rotating shaft 16 away from the bearing seat 17, and the driving pulley 19 is connected to the driven pulley 20 through a transmission belt 21; in addition, a shield 29 is arranged on one side of the crushing box 2, and the transmission assembly, gear 18 and bearing seat 17 are all located in the shield 29.
[0030] Please refer again Figure 7A hinge 22 is connected to one side of the box door 9, and the box door 9 is hinged to the crushing box 2 through the hinge 22; a bracket 23 is provided on the other side of the box door 9, and a notch is provided on the side of the bracket 23 away from the hinge 22; a lock is provided on the other side of the crushing box 2, and the lock includes a fixed plate 24 and a threaded rod 25 hingedly arranged on the fixed plate 24, and a nut 26 is sleeved on the end of the threaded rod 25 away from the fixed plate 24, and the threaded rod 25 is clamped in the notch on the bracket 23. By setting the box door 9, it is convenient to replace the sieve plate 6 after opening the box door 9, but for safety reasons, the box door 9 needs to be kept closed when the crushing device is working.
[0031] In this embodiment, a baffle 27 is provided on the mounting plate 10, and the baffle 27 is provided perpendicular to the length direction of the long hole 12. A threaded hole is provided on the baffle 27, and a second bolt 28 is passed through the threaded hole. The rod of the second bolt 28 abuts against the base of the motor 11. When the first bolt 13 is loosened, the motor 11 can be pushed to slide along the long hole 12 by the forward or reverse rotation of the second bolt 28 in the threaded hole.
[0032] The applicant would like to explain that in actual application, the main transmission mode of the Chinese herbal medicine crusher is belt drive. However, after a long period of operation, this transmission mode will not only easily cause fatigue of the transmission belt 21, but also cause the position of the motor 11 to change, which will cause the transmission belt 21 to become loose, thereby affecting the transmission effect. In order to solve this problem, it is necessary to adjust the position of the motor 11 so that the transmission belt 21 can be tightened again.
[0033] Therefore, the utility model adopts a design in which the mounting plate 10 is tiltedly arranged on the frame 1, and the rod portion of the second bolt 28 abuts against the base of the motor 11. When adjusting, the first bolt 13 on the base of the motor 11 is loosened, and the second bolt 28 is rotated forward in the threaded hole on the baffle 27, so that the second bolt 28 pushes the base of the motor 11 to slide obliquely downward along the long hole 12, thereby realizing the adjustment of the position of the motor 11, which means that the active pulley 19 moves to the side away from the driven pulley 20, thereby realizing the operation of tightening the transmission belt 21; when the transmission belt 21 is re-tightened, the first bolt 13 is finally tightened to fix the position of the motor 11, thereby ensuring the transmission effect of the belt drive method. At the same time, in order to meet the needs of maintenance, it is sometimes necessary to disassemble or assemble the transmission belt 21. At this time, the first bolt 13 can be loosened, and then the second bolt 28 is rotated in the threaded hole on the baffle 27 in the opposite direction to release the limit on the base of the motor 11. Then, the motor 11 can be directly pushed to slide upward along the long hole 12 to make the transmission belt 21 loose, so that the transmission belt 21 can be disassembled and assembled more easily, and the operation is more convenient.
[0034] Also, please refer again to Figure 2 A rubber pad 30 is provided on the lower surface of the sieve plate 6 at one end near the receiving box 8. By providing the rubber pad 30, the receiving box 8 is squeezed when it is inserted into the second discharge port 7, thereby avoiding the problem of slipping of the receiving box 8 under the impact of the material.
[0035] It is worth mentioning that a group of guide plates 31 are arranged above the crushing assembly. The guide plates 31 are connected to the inner wall of the top of the inner cavity of the crushing box 2. The guide plates 31 are inclined toward the crushing rollers 5. The guide plates 31 guide the materials poured into the feed hopper 3.
[0036] The usage of this product is as follows:
[0037] When crushing the Chinese medicinal materials, the Chinese medicinal materials are poured into the feed hopper 3, and the staff starts the motor 11. The output shaft of the motor 11 rotates to drive the driving pulley 19 to rotate, and then drives the driven pulley 20 to rotate through the transmission belt 21. The driven pulley 20 drives the corresponding gear 18 on one of the rotating shafts 16 to rotate. Since the two gears 18 are meshed with each other, the two crushing rollers 5 can rotate relative to each other, thereby realizing the function of crushing the Chinese medicinal materials.
[0038] Furthermore, the Chinese medicinal materials crushed by the crushing roller 5 are screened by the sieve plate 6 when falling. The qualified Chinese medicinal materials can pass through the sieve plate 6 and fall into the first discharge port 4, and then be discharged for collection or entering the next process. Those unqualified Chinese medicinal materials that cannot pass through the sieve plate 6 will slide on the inclined sieve plate 6 and pass through the second discharge port 7 into the receiving box 8. Finally, the receiving box 8 is pulled out from the inside of the support plate 14 through the handle 15 and poured into the feed hopper 3 for another crushing.
[0039] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
